The Washington entry, field by field
This is the registry entry our engine applies for tax year 2026, rendered field by field. Where a field is blank in the registry, the row says so rather than filling the gap.
- Credit for TY2026
- Expired No. The registry records the Washington credit as expired: RCW 82.04.4452 (expired 1/1/2015 - no current credit)
- State form
- None recorded in the registry
- Statute
- RCW 82.04.4452 (expired 1/1/2015 - no current credit)
What this means for a Washington company
Our engine computes no Washington research credit for tax year 2026. The registry entry carries RCW 82.04.4452 (expired 1/1/2015 - no current credit).
That is the whole of what the registry says, and this page will not say more. What does not change is the federal position: the §41 credit is computed from the same substantiated qualified research expenses whichever state the work sits in, and a Washington company with qualifying research claims it on Form 6765 like anyone else.
Claiming it alongside the federal credit
The federal §41 credit comes first. It is computed from the qualified research expenses the study substantiates - wages for qualified services, supplies consumed in research, computer and cloud rental, and the allowable share of contract research - and it lands on Form 6765 with the return.
A Washington company still claims the federal credit in full. What changes without a state credit is only the second layer, not the first. Where the work was physically performed matters: state credits generally reach the research done in the state, so the same employee can sit inside one state's base and outside another's.
That is why the allocation work is done once, at the expense level, with the state attribution recorded as it is built rather than reverse-engineered at filing time.
One base, two computations
- 1 Qualify the activities under the four-part test and total the year's QREs.
- 2 Compute the federal §41 credit and file it on Form 6765.
- 3 Record why no Washington credit is claimed, with the citation, so the file answers the question before anyone asks it.

Registry entry version 2024.1, exported from services/study-api/app/engines/rules_engine.py (STATE_RULES_2024 + STATE_RULES_REGIME_OVERRIDES via RulesEngine.get_state_rules) on September 10, 2026. The registry is versioned per state and per tax year: the entry above governs TY2026, and a study for an earlier year is computed under that year's entry instead.
