Guide: Self-employment tax in Oregon - graduated rates, the federal subtraction, and QBI
Oregon freelancers owe three layers of tax: federal self-employment tax, federal income tax, and Oregon tax. The 2025 single-filer brackets are 4.75% to $4,400, 6.75% to $11,100, 8.75% to $125,000, and 9.90% above that. These thresholds are verified against the official 2025 OR-40 Chart S; older published thresholds of $4,300 and $10,750 are wrong and are not used here.
A single filer subtracts a $2,835 standard deduction for 2025. Oregon also allows a subtraction for federal income tax, capped at $8,500 for 2025 ($4,250 married filing separately) and further limited by AGI, and a $256 credit per exemption. Oregon is disconnected from IRC section 199A, so the federal 20% QBI deduction does not reduce Oregon taxable income. A kicker surplus credit can apply on the 2025 return.
Worked example, before the federal subtraction and exemption credits. On $50,000 of Oregon taxable income, the tax is 4.75% of $4,400 ($209) plus 6.75% of $6,700 ($452.25) plus 8.75% of $38,900 ($3,403.75) = $4,065. That matches the official 2025 OR-40 Chart S. On $100,000 of Oregon taxable income the tax is $209 + $452.25 + 8.75% of $88,900 ($7,778.75) = $8,440.

FAQ
Start from Oregon AGI, subtract the $2,835 standard deduction (single filer, 2025) and the federal tax subtraction, capped at $8,500 and limited by AGI. The worked examples above start from Oregon taxable income, so they are before the $256 per-exemption credits, which reduce the tax itself.
Oregon surplus credit that can apply when state revenues exceed forecasts. It is claimed on the return for the relevant year, and the data sheet notes it applies on the 2025 return. It is a credit, not a rate change, so it does not change the bracket math above.
Some secondary summaries show $4,300 and $10,750, but the official 2025 OR-40 Chart S gives $4,065 of tax at $50,000 of taxable income, which only matches the $4,400 and $11,100 thresholds used here. This page uses the official chart.
Federal estimated payments are generally required if you expect to owe $1,000 or more in federal tax after withholding and credits. Oregon has its own estimated-payment rules and forms, so check the Oregon Department of Revenue for its thresholds and due dates before you skip a quarter.

For 2025 you can subtract federal income tax up to $8,500 ($4,250 for married filing separately), further limited by AGI. The worked examples in the guide below are before that subtraction and before the $256 per-exemption credits.
