Washington R&D Tax Credit Services

No. Washington's Business & Occupation tax credit for R&D expired on December 31, 2014, and has not been reinstated. No legislation has been enacted to restore this state-level incentive as of 2026. Washington companies should focus on claiming the Federal R&D Tax Credit under IRC Section 41, which remains available and can provide significant tax savings.

Yes. Qualified small businesses meeting specific eligibility criteria can elect to apply a portion of their federal R&D credit against payroll taxes instead of income tax. This makes the credit valuable even for pre-revenue or pre-profitable startups that have no income tax liability but do have payroll tax obligations. Maximum credit amounts apply annually, and specific eligibility requirements must be met.

The Federal R&D Tax Credit remains one of the most valuable federal tax incentives available. Washington companies can still achieve significant tax savings through federal credits alone. Additionally, since Washington has no state income tax, companies can focus entirely on optimizing their federal claim without navigating competing state requirements or credit stacking considerations.

Activities must satisfy the four-part test: permitted purpose (developing new/improved business components), technological in nature, eliminates technical uncertainty, and involves systematic experimentation. Common qualifying activities at Washington companies include software development, aerospace engineering, manufacturing process improvements, biotechnology research, clean energy innovation, and video game development.

You can generally amend federal returns to claim R&D credits for the past three years (within the statute of limitations). Many Washington companies discover substantial credits from prior years through lookback studies. Additionally, if you're still within the four-year statute for 2011-2014, you may be able to claim the expired Washington state B&O tax credit through amended state returns.

Maintain comprehensive records including: project-level documentation describing technical uncertainties and experimentation processes, employee time records showing hours devoted to qualified research (including remote workers), detailed financial records supporting wage, supply, and contractor expenses, and technical materials like design documents, test results, and development records. For software companies, include cloud computing expenses and source code repositories.

Yes. Research conducted by employees anywhere in the United States qualifies for the federal credit. Washington companies with remote workers in other states can include those employees' qualifying wages in their federal R&D credit calculation. Maintain documentation of where employees work and what research they perform.

Absolutely. While manufacturing companies often receive significant R&D credits, service companies—especially software, engineering, and technology services firms—regularly qualify. Many Washington SaaS companies, consulting firms, and technology services providers qualify. The determining factor is whether activities satisfy the four-part test, not the industry classification.

Since Washington has no state income tax, the federal credit provides a dollar-for-dollar reduction in federal income tax liability or, for qualifying startups, a reduction in payroll tax obligations. Credits can be carried back one year and forward multiple years if not used immediately. The credit has been made permanent and includes enhanced benefits for startups and small businesses.

While legislators have periodically considered bills to revive the state R&D credit, no legislation has been enacted as of 2026. Companies should monitor state legislative developments but focus current efforts on maximizing federal R&D tax credits, which provide substantial and reliable benefits regardless of state-level changes.
