Portland and Vancouver sit ten minutes apart across the Columbia River, in two states with opposite tax structures. Oregon has one of the highest state income tax burdens on middle incomes in the country; Washington has none. Here is what that looks like at four salary levels, computed exactly the way our salary calculator does it.

The pattern worth noticing
This is the widest gap of any pair here at every salary level, and it is wide from the very bottom — Oregon’s brackets reach 8.75% at income levels where most states are still in low single digits. The offsetting fact every local knows: Oregon has no sales tax and Washington’s is high, so shopping habits genuinely claw some of this back. At $75,000 the difference is about $402.90 a month; at $250,000 it is $1,783.30 a month.
What this comparison doesn’t include
State income tax is one line in a much larger budget. Housing costs, sales tax, property tax rates, and general cost of living all move independently of income tax and can comfortably outweigh it in either direction — a smaller state tax bill does not automatically mean more money left at the end of the month once rent or a mortgage is paid. This comparison isolates income tax because that is the part with a precise, calculable answer.
A note on precision: these figures apply each state’s bracket schedule to your federal taxable income. Washington levies no personal income tax on wages, so its column is federal tax and FICA only. Oregon’s figure comes from its own published brackets. States also have their own credits, exemptions and deductions that this model does not carry, so treat the numbers as a close estimate of the gap rather than a filled-in tax return. The methodology page sets out exactly what is and is not modelled.
Run your own numbers
Every figure above assumes a single filer taking the standard federal deduction and nothing else. Your own result will move with filing status, deductions, and your actual salary — put your real number into the salary calculator for Oregon, Washington, or any other state, and you can share or bookmark the result straight from the page.
