Before you get started
This guide is for customers who have received a notice of assessment (NOA) for one of the following:
- Dyed diesel or biodiesel you used in registered vehicles that drove on Washington highways
- Washington fuel tax you underpaid
If you’re a service agent acting on behalf of someone who has received an NOA letter, you can follow the same instructions as the taxpayer.
Gather the required information
To pay a dyed diesel violation or notice of assessment in License Express, you’ll need:
- The Letter ID in the upper right corner of the NOA letter we sent you
- Your bank account and routing numbers or your credit card number, depending on how you want to pay the fee
If you don't have your NOA letter, email us at DOL-PRFTCompliance@dol.wa.gov to get help finding your Letter ID.
