## Overview of Dyed Fuel Excise Tax Changes
Under the One, Big, Beautiful Bill (OBBB), starting **December 31, 2025**, U.S. law has changed how excise taxes on dyed fuel are treated. Entities that paid excise taxes on fuel (such as diesel or kerosene) and then removed fuel from terminals as dyed fuel for **nontaxable** uses may now claim a **refund via updated Form 8849 and Schedule 5** under temporary regulations effective immediately ([irs.gov](https://www.irs.gov/newsroom/treasury-irs-provide-guidance-on-a-new-method-for-recovering-federal-excise-tax-paid-on-dyed-fuel-established-under-the-one-big-beautiful-bill?utm_source=openai)).
## Who’s Affected & What Qualifies
Entities that should pay attention include:
- Farms, construction companies, municipalities, generators, and any business using dyed diesel in off-road or exemption contexts.
- Traders or fuel distributors who handle fuel removed from terminals and later dyed for exempt purposes.
Criteria to qualify:
1. Fuel was taxed originally and **not already credited or refunded**.
2. Fuel must have been **indelibly dyed** by mechanical injection and removed for **nontaxable use** on or after **Dec 31, 2025**.
3. Claimant must have **originally paid** the excise tax.
4. Claim sight must follow all reporting and documentation requirements using Form 8849 & Schedule 5 ([irs.gov](https://www.irs.gov/newsroom/treasury-irs-provide-guidance-on-a-new-method-for-recovering-federal-excise-tax-paid-on-dyed-fuel-established-under-the-one-big-beautiful-bill?utm_source=openai)).
## Steps to Setup Your Entity To Comply
### Structuring your fuel accounting system
- Track fuel purchases at terminals and invoices showing excise tax paid.
- Maintain logs for dyed fuel removal, including date, terminal ID, use type, and documentation of dyeing method.
- Update accounting or ERP systems to segregate taxable and nontaxable fuel usage.
### Filing for Refunds
- Use the new updated **Form 8849** and **Schedule 5**, including required documentation.
- Ensure reports accurately reflect fuel originally taxed, dyed, and removed appropriately.
- File timely; since regulations are temporary (expire in up to 3 years unless made permanent), act quickly ([irs.gov](https://www.irs.gov/newsroom/treasury-irs-provide-guidance-on-a-new-method-for-recovering-federal-excise-tax-paid-on-dyed-fuel-established-under-the-one-big-beautiful-bill?utm_source=openai)).
### Operational adjustments
- Educate staff about keeping chain-of-custody for fuel from purchase through use.
- Confirm that terminals used are “approved terminals.”
- Review insurance and environmental rules—dyed fuel often signals exempt usage, regulators may inspect.
## Example: Municipal Road Department
*Township Roads, Inc.* operates in rural county and buys clear diesel fuel, pays excise tax. After removals from terminal, they dye fuel for off-road maintenance equipment usage (not taxed). Under the new rules:
- They document purchase invoice, the dyeing event at approved terminal, and use as exempt.
- In 2026, they submit Form 8849 and Schedule 5 claiming refund for the excise tax paid.
- Their accountant adjusts internal budget forecasting to account for anticipated refunds, reducing operating costs.
## Risk Factors & Penalties
- Missing documentation may lead to rejection of refund.
- Non-indelible dye, non-approved terminals, or incorrect form use will disqualify claim.
- False claims may attract excise tax penalties and interest.
## Actionable Checklist for Entities Considering Claims
| Action | Deadline or Timing |
|--------|----------------------|
| Review fuel use, invoices post-Dec 2025 | ASAP |
| Determine eligibility and perfect documentation | Before filing refund claim |
| Submit updated Form 8849 + Schedule 5 | Within operating cycle or before temporary regs expire |
| Confirm dye method and terminal approval | Permanent practice moving forward |
With proper processes in place, entities can realize important refunds under new law and avoid risk associated with non-compliance.
