If you just moved to Oregon, you’ve probably noticed something weird. No sales tax. You can walk into a store, buy a $1,000 laptop, and pay exactly $1,000. It feels like a glitch in the matrix. But then, you get your first paycheck and reality hits. Oregon’s income tax is hefty. Honestly, it’s one of the highest in the country, especially when you hit the top brackets.
Getting a handle on an oregon state income tax calculator isn’t just about plugging in your salary and hitting enter. It’s about the "kicker." It’s about the transit taxes. It’s about why your neighbor might be getting a massive refund while you’re writing a check to the Department of Revenue.
How Oregon Actually Taxes Your Paycheck
Oregon doesn't play the "flat tax" game. It’s a progressive system. Basically, the more you make, the bigger the slice the state takes.
For the 2025 and 2026 tax years, the rates generally look like this:
- 4.75% on the first few thousand dollars.
- 6.75% for the next chunk.
- 8.75% for most middle-income earners.
- 9.9% on anything over $125,000 (for single filers) or $250,000 (for joint filers).
That 9.9% is the part that usually shocks people. It’s high. But there is a silver lining. Oregon allows you to subtract a portion of your federal income taxes from your state taxable income. Most states don’t do that. For 2025, that subtraction is capped at $8,500. It’s not a total wash, but it helps.
The Weird Math of Withholding
When you use a calculator, you’re usually looking for your "take-home" pay. But Oregon has these "stealth" taxes. There’s a statewide transit tax of 0.1%. It's tiny, but it's there. If you work in the Portland metro area, you might also be hit with the TriMet transit tax or the Supportive Housing Services (SHS) tax.
The SHS tax is a 1% tax on taxable income over $125,000 for individuals. It catches people off guard every single year.
The Oregon Kicker: The State’s "Oops" Fund
You cannot talk about an oregon state income tax calculator without mentioning the kicker. This is Oregon's most famous—and confusing—tax quirk.

Here is the deal: Every two years, Oregon economists guess how much tax revenue the state will collect. If they are wrong by more than 2%, the state has to give the excess back to the taxpayers.
For the 2025 tax year (the returns you file in 2026), the kicker is officially happening. The state confirmed a $1.41 billion surplus.
Calculating Your Share
Your kicker isn't a flat check in the mail. It’s a credit on your tax return.
- Look at your 2024 tax return.
- Find your "tax liability before credits" (usually line 24 on Form OR-40).
- Multiply that number by 9.863%.
If you paid $5,000 in Oregon taxes in 2024, your 2025 credit would be roughly $493. If you owe the state money, the kicker reduces your bill. If you’re getting a refund, the kicker makes it bigger. Just remember: if you didn't file a 2024 return, you aren't getting a kicker. Period.
Deductions and Credits: The "Standard" Problem
For 2026, things are changing for the better regarding the standard deduction. A recent bill (HB 3753) is set to significantly bump these numbers.
For years, Oregon’s standard deduction was surprisingly low compared to the federal government. For 2026, the proposed jump is massive:
- Single filers: Moving from around $2,835 to potentially **$4,840**.
- Joint filers: Jumping to $9,680.
This change is designed to help lower-income Oregonians who currently pay taxes on almost every dollar they earn. Unlike the federal government, which gives you a huge "0% bracket" via the standard deduction, Oregon starts taxing you almost immediately.

Credits You Might Actually Use
- The Oregon Kids Credit: This is huge for 2025. If you make less than $31,550, you could get up to $1,050 per child under age 6.
- Working Family Household and Dependent Care (WFHDC): This helps cover childcare costs while you work or go to school.
- Oregon College Savings Plan: You don't get a deduction for contributions anymore; instead, you get a refundable credit of up to $180 ($360 for joint filers) depending on your income.
Don't Forget the Local Surcharges
If you live in Multnomah County, your oregon state income tax calculator results will look very different from someone in Bend or Medford.
Portland residents are subject to the Arts Tax. It’s a flat $35. It sounds simple, but the city is aggressive about collecting it. Then there’s the Multnomah County Preschool for All tax. This is another 1.5% to 3% on high earners.
When you add the 9.9% state rate, the 1% Metro SHS tax, and the 1.5% Preschool tax, top earners in Portland can face a marginal state and local rate of over 12%. That puts the area in the same conversation as NYC and California.
Putting It All Together: A Practical Example
Let’s say you’re single, living in Eugene, making $75,000.
You’ll take your $75,000 and subtract your federal tax (up to the $8,500 cap) and your Oregon standard deduction. Your "taxable income" for the state will likely be around $64,000.
The first few thousand are taxed at the low rates (4.75% and 6.75%), but the vast majority of that $64,000 will be hit with the 8.75% rate.
Total tax? You’re looking at roughly $5,000 to $5,500.

But wait! If you had a tax liability of $5,000 last year, you’d subtract your ~10% kicker credit (about $500). Now your bill is down to $4,500.
Common Misconceptions
People often think the kicker is "free money." It's not. It's your money. The state just overcollected.
Another big one: "I don't need to file because I don't owe anything." If you are eligible for the kicker or the Oregon Kids Credit, you must file a return to get that money. Even if your income was zero, filing is the only way to trigger those refundable credits.
Your Next Steps for Tax Season
First, go find your 2024 tax return. You need that "tax liability" number to estimate your kicker. Without it, any oregon state income tax calculator you use is just guessing.
Second, check if you're eligible for the new 2025/2026 credits. If you have kids under 6 or contributed to a 529 plan, those credits are "refundable," meaning they can pay you even if you owe zero tax.
Finally, if you live in the Portland metro area, double-check your employer's withholding for the SHS and Preschool for All taxes. These are often not withheld automatically unless you specifically request it or hit a certain income threshold, leading to a nasty surprise in April.
Gather your 2024 Form OR-40, check line 24, and multiply by 0.09863 to see your 2026 kicker credit today.
