Is Sales Tax Deductible in Washington?
Short answer: Yes, and it's usually your best option: Washington has no income tax, so itemizers deduct sales tax instead (6.5% state rate, about 9.57% with local taxes). Vehicles owe an additional 0.5% motor vehicle sales/use tax (up from 0.3% on Jan. 1, 2026) on top of state and local sales tax.
Use the IRS Sales Tax Deduction Calculator or your receipts, add sales tax paid on a car, boat, or home-building materials, and stay within the $40,400 SALT cap (Schedule A line 5a).
Records to keep: Keep your state return, W-2s and 1099s (1099-R, SSA-1099), and any state credit worksheets. Check your state revenue department's current-year instructions before you file.
