Washington State offers voluntary disclosure programme to international remote sellers

December 5, 2025

Washington State will open a temporary amnesty route, known as a voluntary disclosure programme, for international businesses that sell to customers in the state but have not met their tax obligations. The initiative, aimed at non-US companies, will run from 1 February to 31 May 2026 and gives qualifying businesses the chance to settle past liabilities on more favourable terms than usual.

Who the programme is for

The disclosure option is designed for foreign companies that have created a tax presence—known as nexus—either by operating in Washington physically or by generating more than USD 100,000 in annual sales to customers there, with Business & Occupation tax and potentially sales tax filing obligations in the state. To join the programme, a business must satisfy several conditions:

  • It must be based outside the United States.
  • It must not have registered or filed tax returns in Washington during the current year or the previous four years.
  • The Department of Revenue must not have contacted the business for compliance or enforcement during that same period.
  • The business must not have taken steps to conceal or misstate its tax position.

What participants gain

Businesses accepted into the programme will only need to address unpaid business and occupation (B&O) tax for the current year and the four years before it, plus one year of uncollected retail sales tax, if sales tax applies to their goods and/or services. Businesses that do not use the programme and are later identified by the state face a standard seven-year lookback for both taxes.

Penalties— which can normally reach 39%—will be waived. Interest still applies at statutory rates.

Washington’s B&O tax applies broadly to businesses with nexus, even where no retail sales tax is due. It is charged on gross income at rates between 0.471% and 2.1% and is paid by the business, not passed to customers.

Applying to the programme

Applications must be submitted online once the window opens on 1 February 2026. Businesses should prepare:

  • Basic business details. Anonymous submissions may be made initially, but the company must reveal its identity within 15 calendar days or restart the process.
  • A gross income schedule in the Department’s required format.
  • A completed Washington Business Activities Questionnaire.
  • An authorisation allowing the Department to communicate with the business or its representative by email or fax.
  • Any supporting documents, such as exemption certificates or reseller permits.

Next steps and timelines

After applying, businesses will need to register formally with the Department through the online Business Licensing Wizard to ensure future reporting is in place.

If the Department accepts an application, it will issue an agreement that must be signed and returned within 30 days. Missing this deadline may cancel the application and reinstate the usual seven-year lookback and penalties.

If additional information is needed, the examiner will request it. Any outstanding documents must be provided within 60 days of the original application. Once everything is complete, the Department will issue a draft assessment, followed by a final assessment through the applicant’s online account. Payment must be made by the deadline shown to avoid extra charges.

If an application is not approved

Applicants who do not meet the programme criteria will receive written reasons and advice on alternative routes. Businesses that already have a Washington registration may still qualify for a small (5%) penalty reduction, and those with unregistered activity predating their initial registration may receive some programme benefits if the other rules are met.

Foreign businesses selling to customers in Washington should first check the Department of Revenue’s website to confirm whether they are already listed.
