Iowa Fuel Tax Rate Changes Effective July 1, 2024
The Iowa fuel tax rate for undyed biodiesel classified as B-11 to B-19, undyed biodiesel classified as B-20 or Higher, and ethanol blended fuel classified as E-15 or Higher and Alcohol will change July 1, 2024. All other Iowa fuel tax rates will remain the same. All rates and effective dates are available under the Iowa Fuel Tax section of the Iowa Fuel Tax Rates and Descriptions page.
Fuel Tax Inventory Return for 2024
Per Iowa Code 452A.85, an Iowa Fuel Tax Inventory Return will be required for persons having title to fuels in storage and held for sale on July 1, 2024, where there is an increase in the tax rate in excess of one-half cent per gallon. Fuels classified as B-11 to B-19 and fuels classified as E-15 or Higher will have fuel tax rate increases of more than one-half cent per gallon and will be required to be reported on the 2024 Iowa Fuel Tax Inventory Return due July 31, 2024.
The 2024 Iowa Fuel Tax Inventory Return shall be submitted electronically by persons having a motor fuel retailer account or a motor fuel eligible purchaser account. The return shall be submitted on paper for persons without an account.
For retailers and eligible purchasers, the returns shall be filed electronically via GovConnectIowa by clicking on the link “File 2024 Motor Fuel Inventory Return” shown on the respective account. If you have both a retailer account and an eligible purchaser account, only one return needs to be filed, file it on the retailer account.
If you do not have a retailer account or eligible purchaser account and need to submit an inventory return, please complete and submit the paper form 2024 Fuel Tax Inventory Return (80-020).
Please note a return is not necessary for undistributed fuels in registered IRS gasoline terminals or undistributed fuels in storage facilities destined for registered IRS gasoline terminals as the appropriate fuel tax rate will attach to those fuels once they reach the point in the distribution process where the tax attaches, which is known as “withdrawn from terminal”.
Income Tax Credits and Sales/Use Tax Refunds for Use, Sale, and Production of Fuel
Income tax credits have been instituted in recent years that relate to the use, sale, and production of fuel; however, these credits do not impact fuel tax. A sales/use tax refund is also available for producers of biodiesel. To access forms and information regarding these credits and refunds, go to our forms index.
The point of taxation for fuel (except LPG, CNG, & LNG) in Iowa is the terminal rack or supplier level. All fuel leaving the pipeline distribution system must have the tax paid. Only dyed special fuel used for off-highway purposes and fuel exported outside of Iowa is sold tax-free.
Tax is imposed on three categories of fuel:
- Motor fuel: gasoline, ethanol-blended gasoline, alcohol, and aviation gasoline
- Special fuel: diesel, aviation (jet) fuel, liquefied petroleum gas (LPG), compressed natural gas (CNG), liquefied natural gas (LNG) and biodiesel
- Electric Fuel: kWh for non-residential charging
Current Iowa fuel tax rates (select Iowa Fuel Tax)
Ethanol Blended Gasoline
Ethanol blended gasoline is defined as motor fuel which has been blended with alcohol distilled from cereal grains, the end product containing a minimum percent of alcohol.
Examples:
To make a properly blended 8,000 gallons of E-10, the blend requires:
- 7,200 gallons of gasoline + 800 gallons of alcohol = 8,000 gallons of ethanol blended gasoline
- E-10 gasoline is ethanol blended gasoline that contains a minimum percentage of between 10 percent and 14 percent by volume of ethanol.
To make a properly blended 8,000 gallons of E-15, the blend requires:
- 6,800 gallons of gasoline + 1,200 gallons of alcohol = 8,000 gallons of ethanol blended gasoline
- E15 or higher gasoline is ethanol blended gasoline that contains a minimum percentage of between 15 percent and 99 percent by volume of ethanol.
Biodiesel
"Biodiesel" means an oxygenated product derived from soybean oil, vegetable oil, or animal fats that can be used in diesel engines including aircraft. Biodiesel may be a blend with diesel fuel or it may be 100 percent soybean oil, vegetable oil, or animal fats. Any biodiesel product is taxed as a special fuel. B-20 or higher is a special fuel that contains a minimum percentage of 20 percent by volume of biodiesel.
Supplier
A person who:
- Acquires motor fuel or special fuel by pipeline or marine vessel from a state, territory, or possession of the United States or from a foreign country for storage at and distribution from a terminal and who is registered under 26 U.S.C. 4101 for tax-free transactions in gasoline or
- Produces alcohol or alcohol derivative substances in this state or acquires it by truck, railcar, or barge for storage at and distribution from a terminal or
- Produces or acquires biofuel or biodiesel for storage at and distribution from a terminal or
- Produces, manufactures, or refines motor fuel or special fuel in this state.
"Supplier" also includes a person who does not meet the jurisdictional connection to this state but voluntarily agrees to act as a supplier for purposes of collecting and reporting the motor fuel or special fuel tax.
Note: A retail dealer or wholesaler who merely blends alcohol with gasoline or biodiesel with diesel before the sale or distribution of the product or a terminal operator who merely handles, in a terminal, motor fuel, or special fuel consigned to the terminal operator does not qualify as a supplier.
Importer
A person who imports untaxed motor fuel or non-dyed special fuel in bulk or transports loads into the state by truck, rail, or barge.
Restrictive Supplier
A person not licensed as an importer but who imports untaxed motor fuel or non-dyed special fuel into this state in amounts of less than 4,000 gallons in tank wagons or in small tanks.
Blender
A person who owns and blends alcohol with gasoline to produce ethanol blended gasoline at a non-terminal location. A blender is also a person who blends special fuel products at a non-terminal location where the tax has not been paid on all of the products blended.
Examples:
- Gas + Alcohol = gasohol or ethanol blended gasoline
- Diesel + Soy Oil = biodiesel
Exporter
A person who acquires fuel in this state for export to another state. This person must be licensed in the state the fuel is exported to, so the tax can be paid to that state.
Eligible Purchaser
A distributor of motor fuel or special fuel who elects to make delayed tax payments to a licensed supplier by EFT.
Eligible Purchaser End User
An end user of special fuel who has purchased a minimum of 240,000 gallons of special fuel in each of the preceding two years who elects to make delayed payments to a licensed supplier by EFT.
Licensed compressed natural gas (CNG), liquefied natural gas (LNG), liquefied petroleum gas (LPG), or hydrogen dealer
A person in the business of handling untaxed compressed natural gas, liquefied natural gas, liquefied petroleum gas, or hydrogen who delivers any part of the fuel into a fuel supply tank of any motor vehicle. A dealer may also fuel the dealer’s own vehicles under this license.
Licensed compressed natural gas (CNG), liquefied natural gas (LNG), liquefied petroleum gas (LPG), or hydrogen user
A person who dispenses compressed natural gas, liquefied natural gas, liquefied petroleum gas, or hydrogen for highway use, upon which the special fuel tax has not been previously paid, from fuel sources owned and controlled by the person into the fuel supply tank of a motor vehicle or commercial vehicle owned or controlled by the person.
Licensed compressed natural gas (CNG), liquefied natural gas, liquefied petroleum gas (LPG), or hydrogen consolidated
A separate license is required for each location where CNG, LNG, LPG, or hydrogen is delivered into the fuel supply tank of a motor vehicle. For reporting purposes a licensee may file a separate return for each separately licensed location; or, if arrangements have been made with the Department, the licensee may file a consolidated return reporting all sales made at all locations for which a license is held. However, a consolidated return may not be used to combine dealer and user operations.
Storage Facility
A motor fuel, alcohol, or special fuel storage and distribution facility (IRS registered terminal or non-terminal) which fuel is delivered into, stored within, withdrawn from or sold from. This includes ethanol plants and biodiesel plants. (see ethanol plant and biodiesel plant information)
Transportation (Common Carrier or Contract Carrier)
A person involved in the movement of motor fuel or special fuel imported into the state, who is not the owner of the motor fuel or special fuel.
Retail Dealer (Dealer)
A person, other than a distributor, who engages in the business of selling or distributing motor fuel or special fuel to the end user in this state.
The only method of determining gallons of any purchase or sale of motor fuel or special fuel and distillate fuel is on a gross volume basis. Iowa fuel tax computations are based on gross gallons, not net gallons. A temperature-adjusted or other method may not be used except as it applies to liquefied petroleum gas and the sale or exchange of petroleum products between petroleum refineries.
Iowa allows for the sale of ethanol from the ethanol storage of an Iowa licensed supplier in an IRS gasoline/diesel terminal to another Iowa licensed supplier within the terminal as a tax free transaction. The tax shall be paid by the licensed supplier when the invoiced gross gallonage of the alcohol or the alcohol part of the ethanol blended gasoline is withdrawn from a terminal for delivery in this state. This makes the licensed supplier responsible for the tax on both the alcohol and the gasoline portions of the ethanol blended gasoline and allows for the reporting and accounting of this fuel at the proper ethanol blended gasoline percentage and tax rate on the supplier report.
Iowa allows for the sale of B100 or B99.9 from the B100 storage of an Iowa licensed supplier in an IRS gasoline/diesel terminal to another Iowa licensed supplier within the terminal as a tax free transaction. The purchasing Iowa licensed supplier will be responsible for collecting and remitting the Iowa fuel tax when the fuel is withdrawn from the terminal.
Any fuel including denatured alcohol and B100 or B99.9 or imported into Iowa with destination of an IRS gasoline/diesel terminal (IRS gasoline terminal number on invoice or bill of lading) is not subject to Iowa fuel tax. The tax is due when withdrawn from the terminal.
Note: Manly Terminal LLC is not an IRS terminal.
Any fuel, except dyed diesel, but including denatured alcohol imported into Iowa with destination other than an IRS gasoline/diesel terminal, is subject to Iowa fuel tax. An importers license is the proper license to report and pay the Iowa fuel tax due. Tax is due when the shipment comes across state line. B100 may be exempt - refer to biodiesel plant section.
Who Collects and Remits the Tax?
For motor fuel and special fuel (except LPG, CNG, and LNG), the tax attaches when the fuel is "withdrawn from terminal." Withdrawn from terminal means physical movement from a supplier to a distributor or eligible end user or from an alcohol manufacturer to a non-terminal location, and includes an importer going out of state and obtaining fuel from a terminal and bringing the fuel into the state, and a restrictive supplier bringing fuel into the state even though not purchased directly from a terminal. Exchange of product by suppliers while in the distribution channel is not to be considered withdrawn from terminal.
The tax is payable to the Department by the supplier, restrictive supplier, importer, blender, or any other person who possesses taxable fuel upon which the tax has not been paid.
LPG, CNG, and LNG: These fuels are not taxed until the use is determined. Tax attaches to LPG, CNG, and LNG when:
- The LPG or LNG is placed in a fuel supply tank of a motor vehicle or
- The CNG is delivered into equipment for compressing the gas for subsequent delivery into the fuel supply tank of a motor vehicle
Exemptions
Motor fuel or undyed special fuel, except LPG, CNG, or LNG, sold for export to a person holding a valid Iowa exporters license is exempt from the fuel tax. The fuel is considered sold for export only if the bill of lading or manifest indicates that the destination of the fuel withdrawn from the terminal is outside the state of Iowa. Dyed diesel fuel used for off-highway purposes is also exempt from fuel tax.
LPG, CNG, or LNG sold by dealers from highway storage may be sold tax free provided it is sold for one of the following uses:
- Reefer unit, provided there is no possible connection to the power source of the vehicle or
- Fuel supply tank of a non-highway vehicle or
- Carry out container.
When LPG, CNG, or LNG is sold from highway storage for any of the above purposes, an exemption certificate must be prepared and retained by the seller. The exemption certificate must include the date, seller's name and license number, invoice number, use of the fuel, type of vehicle or container, and the name, address, and signature of the purchaser.
All other sales must include the Iowa fuel tax.
The tax computation for a supplier includes a distribution allowance of 1.6 percent of the motor fuel gallonage and 0.7 percent of the undyed special fuel gallonage removed from the terminal during the reporting period. The supplier should pass this allowance to the distributor or dealer.
The distributor purchasing the fuel from the supplier is entitled to 1.2 percent of the motor fuel distribution allowance. The distributor or dealer purchasing fuel from a supplier is entitled to 0.35 percent of the undyed special fuel distribution allowance. The distribution allowance does not apply to fuel exported. The distribution allowance is not available for importers, restrictive suppliers and blenders.
Iowa Fuel Tax Deduction for Blended Fuel Sales
Following Governor Reynolds signature of House File 2128 on May 17, 2022, the Department released guidance to explain this tax change. This new deduction, added to Iowa Code section 452A.8, is intended to promote the use of biofuels by allowing a lower tax rate to be charged when the fuel is withdrawn from the terminal when it is known that the fuel is going to be blended into a biofuel with the lower tax rate after it has been withdrawn. The deduction is for gasoline or diesel fuel withdrawn from a terminal by a licensee to be blended with a biofuel after it is withdrawn from the terminal when the tax rate on the gasoline or diesel fuel exceeds the tax rate which would be due on the biofuel-blended fuel. This tax change is effective July 1, 2022.
This chart below only covers the movement of alcohol from an Iowa ethanol plant to an IRS gasoline terminal, for export outside of Iowa or for sale in Iowa.
Iowa Alcohol Manufacturer (Ethanol Plant) | |||
---|---|---|---|
Marketer, Broker | Iowa Licensed Supplier or Blender | Marketer, Broker | Marketer, Broker |
Export | Non-Terminal Location in Iowa (Ex: Bulk Plant, Retailer, Consumer) | IRS Gasoline Terminal | |
No Iowa Fuel Tax Due | No Iowa Fuel Tax Due | Iowa Fuel Tax Due | No Iowa Fuel Tax Due |
Tax due by Supplier or Blender | Tax reporter and due by Ethanol Plant as Supplier | Tax due when withdrawn from terminal |
Sale for Export
If an ethanol plant is selling for export out of Iowa, whether through a middleman or not, there is no Iowa fuel tax collected or due to state of Iowa. The out-of-state purchaser needs an Iowa exporters license.
Sale in Iowa to Non-Terminal Location
If the middle scenario shown above exists, the ethanol plant is required to collect and pay Iowa fuel tax under a supplier license.
Sale for IRS Gasoline Terminal
If an ethanol plant is selling ethanol bound for an IRS gasoline terminal, then no Iowa fuel tax is due at this point. The Iowa fuel tax is imposed when it is withdrawn from the IRS terminal. Persons with alcohol storage in the IRS terminal and those who own the alcohol in the IRS terminal up to and including withdrawal will be required to be registered as a storage facility and file with the Department. If the middleman or marketer or broker has no ownership of the product when leaving the ethanol plant or later, they do not need a license if the ethanol plant is reporting all transactions properly. If the middleman or marketer or broker does take ownership of product, then two options are available:
- No license needed if the ethanol plant is reporting all transactions with all detail properly.
- If due to proprietary or other contractual arrangements, the ethanol plant does not know all detail to report, then the marketer must have a storage facility license and file a schedule of receipts of all loads of ethanol or E85 received and a schedule of disbursements for all loads of ethanol or E85 sold.
Other persons in the middle scenario above such as a bulk plant, jobber, retailer, or consumer who may later own this ethanol do not normally need a license or file returns or schedules since the Iowa fuel tax should have been charged and collected as required. However, if no Iowa fuel tax is charged and collected; they can be held liable for the tax.
The following Iowa fuel tax licenses are or may be required:
- Storage facility license required for each location. Register on GovConnectIowa.
- Supplier license may also be required. Register on GovConnectIowa.
- Refund Permit - Ethanol plants typically purchase a denaturing product for the alcohol. Since this denaturing product is usually a fuel on which Iowa fuel tax was paid, they are entitled to file for a refund for this fuel tax paid. A refund permit is required before refunds can be issued. Complete the Register on GovConnectIowa. Type of permit: Denaturing Alcohol (54).
Other requirements for storage facility and supplier licenses:
- Must report ALL fuel transactions electronically.
- Storage facility license must report ALL fuel transactions, both disbursements and receipts. Include receipts of fuel which become part of the ethanol sold.
- Supplier license for ethanol plants report only transactions where Iowa fuel tax is due.
- Ethanol plant is required to have either the state to which the fuel is being exported (delivery address, not billing address) or if delivered to an Iowa location, the IRS gasoline terminal code on each invoice; if neither of these requirements is met, Iowa fuel tax is due. Iowa fuel tax computations are based on gross gallons, not net gallons.
An ethanol plant may also be a producer of E-10 to E-14 or E15 or higher.
They could either sell the E-10 to E-14, or E-15 or higher acting like a wholesaler or sell as a retailer directly to the final consumer. Ethanol plants report these sales of E-10 to E-14 or E15 or higher on their supplier license and pay the appropriate Iowa fuel tax to the Department (fuel tax due on untaxed portion of the sale).
Ethanol plants should have purchased the gasoline portion (in addition to the denaturant portion) of the ethanol with Iowa fuel tax paid. If Iowa fuel tax paid on the gasoline portion was greater than the rate charged to the consumer, the ethanol plant would be entitled to a tax overpaid on blended fuel refund. Tax Overpaid or Underpaid on Blended Fuel (82-012) (within GovConnectIowa), must be filed to claim this refund. This is separate from the denaturant refund.
If the ethanol plant also produces and sells E-10 to E-14 or E15 or higher, their schedule of receipts should include all the fuel purchased to make the E-10 to E-14 or E15 or higher.
Alcohol manufacturer (B) sells unfinished alcohol (no denaturant and not fuel ready) to another alcohol manufacturer (C) for further processing. C puts the alcohol somewhere in the middle of their process to further refine the alcohol, then later adds the denaturant to produce ethanol. B reports the alcohol sales under their storage facility license on a schedule of disbursements with product code 123 (alcohol). This is a nontaxable sale. C reports this alcohol under their storage facility license on schedule of receipts with product code 123 (alcohol). These are also nontaxable.
This chart below only covers the movement of B100 from an Iowa biodiesel plant to an IRS gasoline/diesel terminal, for export outside of Iowa or for sale in Iowa.
Iowa Biodiesel Manufacturer (B100 Plant) | |||
---|---|---|---|
Marketer, Broker | Iowa Licensed Supplier or Blender | Non-Iowa Licensed Supplier or Blender | Marketer, Broker |
Export | IRS Gasoline Terminal | ||
No Iowa Fuel Tax Due | No Iowa Fuel Tax Due | Iowa Fuel Tax Due | No Iowa Fuel Tax Due |
Tax due by Supplier or Blender (if not dyed) | Tax due by B100 Plant as Supplier | Tax due when withdrawn from terminal |
Nonterminal Storage Facility license (714) required per Iowa Code section 452A.15 (3). This license requires monthly electronic filing of a schedule of disbursements (schedule code 15B) detailing all B100 or B99 sold. It also requires schedule of receipts (Schedule code 15A) of any fuel purchased which is blended with B100 or B99. Penalties for failure to file start at $100 a month and increase by $100 a month.
Sale for Export
If a biodiesel plant is selling for export out of Iowa, whether through a middleman or not, no Iowa fuel tax collected or due to state of Iowa. The out-of-state purchaser must provide seller with copy of their Iowa exporters license (711). Out of state location must be on the bill of lading or invoice.
Sale to IRS Gasoline/Diesel Terminal
If a biodiesel plant is selling B100 bound for an Iowa IRS gasoline/diesel terminal (IRS gasoline terminal number on invoice or bill of lading), then no Iowa fuel tax is due at this point. The Iowa fuel tax is imposed when it is withdrawn from the IRS terminal. Persons with biodiesel storage in the IRS terminal must be licensed as a supplier and file with the Department. Schedules filed should include an IRS terminal number in one of the destination fields.
Sale in Iowa to Non IRS Terminal Location
If either two of the middle scenarios shown above exists, the biodiesel plant may be required to collect and pay Iowa fuel tax under a supplier license. If purchaser has an Iowa suppliers (704) or blenders (707) license, then no Iowa fuel tax due. Note: The person with the blender license can choose to have the plant charge the tax, instead of paying on their blender's license. If purchaser does not have either of these licenses, Iowa fuel tax due at diesel fuel tax rate.
If Iowa fuel tax is due, then biodiesel plant is required to have an Iowa supplier’s license (704). Monthly electronic filing required. Report only those sales where Iowa fuel tax is due on this supplier’s license.
Dyed biodiesel
B100 or B99 which becomes dyed special fuel is exempt from Iowa fuel tax or subject to refund if Iowa fuel tax was already paid.
B100 or B99 imported into Iowa
Iowa fuel tax is due on the B100 or B99 when it enters the state unless going to an IRS gasoline/diesel terminal (IRS terminal number on invoice or bill of lading) or being sold to an Iowa licensed blender or sold to an Iowa licensed supplier.
If sold to the licensed supplier or blender, they would be responsible for the tax. Tax is due when the shipment comes across the state line.
If the destination is IA when it’s pulled from the out of state IRS terminal, then the supplier in the terminal should collect and pay the Iowa fuel tax. However if pulled from a NE terminal and the destination is NE, but the customer imports the fuel into Iowa, then Iowa fuel tax is due.
The license status of your customer can make a difference. If they are an Iowa licensed blender, they can choose to be the person responsible for the Iowa fuel tax on B100.
If the middleman or marketer or broker has no ownership of the product when leaving the biodiesel plant or later, they do not need a license if the biodiesel plant is reporting all transactions properly. If the middleman or marketer or broker does take ownership of product, then two options are available:
- No license needed if the biodiesel plant is reporting all transactions with all detail properly.
- If due to proprietary or other contractual arrangements, the biodiesel plant does not know all detail to report, then the marketer must have a storage facility license and file a schedule of receipts of all loads of diesel or biodiesel received and a schedule of disbursements for all loads of biodiesel sold.
Other persons (non suppliers and blenders) in the middle scenario above such as a bulk plant, jobber, retailer, or consumer who may later own this biodiesel do not normally need a license or file returns or schedules since the Iowa fuel tax should have been charged and collected as required. However, if no Iowa fuel tax is charged and collected; they can be held liable for the tax.
The following Iowa fuel tax licenses are or may be required:
- Storage facility license required for each location. Register on GovConnectIowa.
- Supplier license may also be required. Register on GovConnectIowa.
Other requirements for storage facility and supplier licenses:
- Must report ALL fuel transactions electronically.
- Storage facility license must report ALL fuel transactions, both disbursements and receipts. Include receipts of fuel which become part of the biodiesel sold.
- Supplier license for biodiesel plants report only transactions where Iowa fuel tax is due.
- Invoices - Biodiesel plant is required to have either the state to which the fuel is being exported (delivery address, not billing address) or if delivered to an Iowa location, the IRS gasoline/diesel terminal code on each invoice or if sold to a licensed supplier or blender at an Iowa location include their name and delivery address; if none of these requirements is met, Iowa fuel tax is due.

The Iowa Department of Revenue is modernizing technology and processes to better serve Iowa taxpayers. As part of this modernization effort, there are changes to the way retailers submit their annual report of the gallons of fuel they have sold during each calendar year for each retail location.
In consultation with the Renewable Fuels Infrastructure Board, motor fuel retailers, and other interested parties, the Iowa Department of Revenue established an annual reporting requirement by Administrative Code rule 701—259.27.
The Annual Fuel Gallons Report can be filed beginning January 1 using the Department’s online portal, GovConnectIowa.
Steps for filing your Annual Fuel Gallons Report:
- Sign into your GovConnectIowa account.
- Don’t have your logon yet? Learn more about signing up for GovConnectIowa and connecting to your current tax accounts.
- After signing in, locate the correct tax account on the Summary screen
- Select the File, Amend, or View Returns link
- Your Annual Fuel Gallons Report will be filed on the Motor Fuel Retailer Return. Locate the correct return for the current year and select the File Now link
- Follow the on-screen instructions to file your Annual Fuel Gallons
- To key in your information for each location, select Manual Entry on the Reporting Method screen.
- To upload your information using an Excel spreadsheet, select Excel Spreadsheet on the Reporting Method screen. You must use the template provided on GovConnectIowa to upload your information
- Review and confirm your information to ensure you correctly keyed the gallons sold for each fuel blend.
After reviewing, select Submit to complete your report.
Failure to timely file a return
A penalty of 10 percent will be added to the tax due for failure to timely file a return if at least 90 percent of the correct amount of tax is not paid by the due date. The penalty can only be waived under limited circumstances.
For each month the required tax is not paid, interest accrues on the unpaid tax at a rate prescribed by law from the due date of the return until payment is received. For purposes of computing interest, each fraction of a month constitutes a whole month. Where the failure to file penalty and one of the other penalties are applicable, the failure to file penalty shall take precedence. No penalty is assessed for late filed reports if no tax is due; however, recurring instances of failure to file reports timely or failure to pay tax timely will result in the imposition of a bond requirement or revocation of the permit.
Failure to timely pay the tax due
A penalty of 5 percent will be added to the tax if at least 90 percent of the correct amount of tax is not paid by the due date. The penalty can only be waived under limited circumstances. For each month the required tax is not paid, interest accrues on the unpaid tax at a rate prescribed by law from the due date of the return until payment is received. For purposes of computing interest, each fraction of a month constitutes a whole month. Recurring instances of failure to file reports timely or failure to pay tax timely will result in the imposition of a bond requirement or revocation of the permit.
Failure to pay electronically
A penalty of 5 percent will be added to the tax due if the payment is not received electronically through ePay or ACH credit as required.
Failure to use the required method of filing
Fuel and LPG tax returns, schedules and reports must be filed through GovConnectIowa. If not, a penalty of 5 percent of the amount of tax due will be added.
Failure to file a transportation, terminal or nonterminal storage facility report
A penalty of $100 for the first violation, and an additional $100 for each subsequent violation occurring within the same calendar year, is imposed for failure to file the required transportation, terminal or nonterminal storage facility reports.
Penalty for improper receipt of refund
If a person files an incorrect refund claim, in addition to the excess amount of the claim, a penalty of 10 percent shall be added to the amount by which the amount claimed and refunded exceeds the amount actually due. If a person knowingly files a fraudulent refund claim with the intent to evade the tax, the penalty shall be 75 percent in lieu of the 10 percent.
Failure to file a Retailer's Annual Fuel Gallons Report
Each dealer is required to file with the Department the Annual Fuel Gallons Report, which details the number of fuel gallons sold during the previous calendar year on both a companywide basis and a site-by-site basis. The Annual Fuel Gallons Report is due by January 31 following the close of the calendar year. A penalty of $100 per location is assessed when a retailer neglects to timely submit the Annual Fuel Gallons Report.
When necessary and advisable to secure payment of tax, the Department may require a bond of any license holder. The Department generally requires a bond on a new applicant only if the applicant has established an unfavorable filing or remittance record on a previous license or if the Department feels the applicant's financial status is such that timely payment of taxes is questionable.
If the license holder is a corporation, an officer of the corporation may assume personal responsibility for the payment of the fuel tax.
