Manufacturing & R&D in Qualifying Counties — Sales/Use Tax Deferral

Provides tax deferral support for Washington manufacturers and research facilities investing in qualifying counties.

Eligibility · United States · US-WA

Washington state's Manufacturing and R&D in Qualifying Counties Sales and Use Tax Deferral allows manufacturing businesses and research and development facilities to postpone payment of sales and use taxes on qualifying capital investments made in Washington counties with populations under 650,000. The program is administered by the Washington Department of Revenue (DOR) and is currently active, with applications accepted through June 30, 2032. The maximum deferral available per applicant is $400,000. Businesses must file an application through the DOR's My DOR online portal before beginning qualifying investment activity, at which point they receive a deferral certificate to provide to vendors and contractors.

Eligibility is restricted to for-profit manufacturing entities and R&D facilities making qualified investments in counties meeting the sub-650,000-population threshold, which excludes Washington's most densely populated counties such as King and Pierce. Universities and research organizations may also qualify under the R&D pathway. Nonprofit organizations do not qualify. The population cap requirement makes this incentive specifically targeted at rural and smaller-metro investment, consistent with Washington's broader policy of directing tax preferences toward under-served economic development areas. There is no competitive scoring process — eligibility is determined by meeting statutory criteria, and qualifying businesses are entitled to the deferral upon approval.

Repayment terms vary by program version but generally require equal installments over several years following the project's operational completion. Businesses should contact DOR's Deferral Program Lead at DORDeferrals@dor.wa.gov before filing to confirm county eligibility and qualifying investment definitions. Because the program functions as an entitlement-style statutory preference rather than a competitive grant, there are no review panels or award cycles — the principal risk is failing to apply before construction begins, which can disqualify an otherwise eligible project.
