## §6435 Recovery of Excise Tax on Dyed Fuel—Basics
Under the One, Big, Beautiful Bill, new provisions let businesses recover federal excise tax previously paid under §4081 when diesel or kerosene fuel later qualifies as **indelibly dyed fuel** under §4082(a). You must be the person who initially paid the §4081 tax and meet certain conditions.

These rules apply to substances removed from a terminal **on or after December 31, 2025**. That’s when eligibility begins.

## Eligibility Criteria & Filing Requirements
To claim under §6435, a business must:
- Have paid §4081 tax on the diesel or kerosene in question (and not claimed credit or refund),
- Removed the fuel from a terminal as eligible dyed fuel on or after Dec 31, 2025,
- Use updated **Form 8849** and **Schedule 5 (Form 8849)** for the claim, providing all required documentation.
- Follow reporting and procedure requirements laid out in the temporary regulations. ([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))

## Temporary Regulations & Effective Dates
- The temporary regulations and proposed rulemaking are **effective immediately** and apply to claims for fuel removed on or after **December 31, 2025**.

## Practical Example
A trucking company purchased clear diesel fuel in November 2025, paid §4081 excise tax. In **January 2026**, that same fuel is removed from a terminal as indelibly dyed fuel for agricultural use (nontaxable under §4082):
- Because removal happened after Dec 31, 2025, the company may file a claim under §6435 for the §4081 tax paid, using Form 8849 and Schedule 5.
- Must be the person who paid the tax originally.
- Ensure records show dyeing procedure and terminal removal fairly.
