- 7.5% Effective (Top 9.9%)

- 4.75% to 9.90%
Oregon has a high top marginal rate of 9.90% spread across four brackets, and uniquely no sales tax at all, which it replaced with a slightly higher income tax. Oregon is the only state in the country with neither a general sales tax nor a gross receipts tax, which makes it a genuine consideration for a contractor whose spending is business-heavy rather than consumption-heavy.
Local taxes: Oregon has no local income tax and no local sales tax, so the state rate applies uniformly to a Portland or Eugene contractor. TriMet and other transit districts levy small payroll taxes on wages only.
State revenue agency: Oregon Department of Revenue.Oregon requires quarterly estimated payments if you expect to owe $1,000 or more, with the standard four federal deadlines. The Oregon Department of Revenue does not issue a separate voucher form; payments are made through the federal Form 1040-ES schedule B instructions.
Tax Strategy for freelance developers
For a software contractor the deductions are unusually clean: a home office deduction calculated on the business share of square footage, a computer and peripherals, and software subscriptions. The home office deduction is the highest-value item because it applies even if you work on a leased laptop, and it reduces the business income on which both self-employment tax and federal income tax are computed.
Contract revenue is lumpy and often back-loaded, with large invoices paid 30 to 60 days after delivery. If you invoice in December and get paid in January, the income belongs to the year it was received, so watch the accrual timing when you compare a strong year against your 1040-ES safe harbour.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.

How much should a freelance developer set aside for quarterly taxes in Oregon?
Set aside about 28.4% of everything you bill — 28.4% of $115,000 in gross income is $32,614 a year, or $8,154 per quarter. That total covers self-employment tax (15.3% on 92.35% of net profit), federal income tax on the remainder after your standard deduction, and Oregon adds roughly 7.5% on your taxable Oregon income. The percentage is measured against gross income rather than net profit because that is the number that actually reaches your bank account and the number you can safely divert.

IRS Form 1040-ES estimated payments for 2026 are due April 15 (Q1), June 15 (Q2), September 15 (Q3), and January 15, 2027 (Q4). Oregon requires quarterly estimated payments if you expect to owe $1,000 or more, with the standard four federal deadlines.
