Tax burden on Washington rentals

Property tax

0.87%

effective rate on median home value

At 0.87% effective, the property tax burden sits in the lower half nationally (rank 24 of 51). Modest annual carrying cost keeps cash flow projections realistic on median-priced homes.

State income tax

None

top marginal rate

No state income tax means rental income and gains from sales flow through your federal return without a state surcharge. This is a structural tailwind for long-term portfolio compounding, especially if you plan to sell into gains later.

Security deposit rule

No statutory cap on security deposits. Landlords set the deposit at whatever the market accepts — typically one to two months' rent, sometimes more for higher-risk applicants or pets. Local ordinances may still apply.

Note: no state income tax; capital gains tax over $250K applies

Deposit rules change; verify current statute before drafting a lease.
