You’ll learn who needs to file, which forms apply to your situation, how to calculate your Oregon taxable income, and how to submit your return to the Department of Revenue properly. It also outlines payment options, refund tracking, and avoiding common errors.

If you lived or worked in Oregon during 2016—even for part of the year—this article will help you understand your income tax responsibilities and walk you through the filing process using official guidance. Whether you file electronically or by paper, you'll find everything you need here to stay compliant and get any refund owed to you.

Who Needs to File a 2016 Oregon Tax Return

Not everyone must file a 2016 Oregon tax return, but many taxpayers are. In most cases, if you were required to file a federal tax return, you’ll likely need to file a state return. Oregon’s filing rules depend on your residency status, income level, and whether Oregon income tax was withheld during the year.

Basic Filing Requirements

You must file your 2016 Oregon tax return if you meet any of the following criteria:

  • You were required to file a federal tax return for 2016.
  • Oregon income tax was withheld from your wages or other payments.
  • Your total income is above Oregon’s residency and filing status thresholds.

These thresholds vary based on your federal taxable income and whether you were a full-year, part-year, or nonresident.

Income Thresholds for Full-Year Residents

  • Single: $5,900

  • Married Filing Jointly: $11,805

  • Married Filing Separately: $6,900

  • Head of Household: $8,575

  • Qualifying Widow(er): $8,215

You must file an Oregon return if your gross income was at or above the threshold for your filing status.

Filing Rules for Part-Year Residents and Nonresidents

The thresholds are lower for part-year residents and nonresidents. If your Oregon-source income was more than:

  • $2,155 as a single filer
  • You must file $4,315 as joint filers, even if you're only subject to Oregon income tax for part of the year.

Other Filing Situations

You should also file if you're claiming a refund of Oregon taxes withheld or if you qualify for any state tax credits. E-filing ensures you receive either a refund or a tax benefit. Even if you're otherwise exempt based on income

If you're sure, check whether your income was subject to Oregon tax and compare it against these thresholds. The Department of Revenue provides detailed instructions to help taxpayers verify their filing requirements.

Forms You Need to File Your Oregon Return

Before you can complete your Oregon tax return for 2016, you’ll need to choose the correct form based on your residency status. Oregon provides three primary forms for individual taxpayers and several supporting schedules.

Main Individual Tax Forms

  • Form OR-40 (Full-Year Resident): For Oregon residents who lived in the state the entire year.
  • Form OR-40-P (Part-Year Resident): For those who moved into or out of Oregon during 2016, or for joint filers where only one spouse was a full-year resident.
  • Form OR-40-N (Nonresident): For those who lived outside Oregon for the entire year but had Oregon-source income.

Each form starts with your federal adjusted gross income and is used to calculate your Oregon taxable income, apply deductions or credits, and report contributions to qualifying programs like the Oregon 529 College Savings Plan.

Supporting Schedules and Vouchers

  • The Supporting Schedules, Schedule OR-ASC (OR-40) and Schedule OR-ASC-NP (OR-40-P and OR-40-N), report additions, subtractions, and credits: Report additions, subtractions, and credits here.
  • Form OR-40-V: Use this payment voucher if you are sending a check or money order.
  • Form OR-EXT: Submit this if you’re requesting an extension to file.

For Small Business Owners

Depending on how your business is structured, additional forms may be required:

  • Sole Proprietorship: Report business income directly on your return using information from your federal Schedule C.
  • Partnerships: Must file Form OR-65 if there’s income from Oregon sources or Oregon-based partners.
  • S Corporations: File Form OR-20-S if doing business in Oregon.
  • LLCs: Follow federal classification. Single-member LLCs usually file as sole proprietors; multi-member LLCs typically file as partnerships.

All forms and instructions are available through the Oregon Department of Revenue’s official website and can be obtained through registered tax professionals or authorized agents.

Step-by-Step Instructions to Complete Your Return

Filing your Oregon tax return starts with one crucial task: completing your federal return. Oregon begins its calculations with your federal adjusted gross income (AGI), so you’ll need that finalized before proceeding.

Step 1: Complete Your Federal Return First

Use your federal return (Form 1040, 1040A, or 1040EZ) to determine your starting point. Oregon relies on the AGI reported on your federal return to calculate your Oregon taxable income.

Step 2: Determine Your Filing Status and Residency

Your Oregon filing status must match your federal status. You’ll also need to confirm your residency status—this determines which Oregon form to use and what portion of your income is subject to Oregon tax.

Step 3: Enter Personal Information

Fill out your name, address, Social Security number, and filing status on your Oregon form. Joint filers must include information for both spouses.

Step 4: Report Your Income

Begin with your federal taxable income, as shown on your federal return. Oregon will apply its additions and subtractions to adjust your total income.

Step 5: Additions to Income

Some income not taxed at the federal level is added back on your Oregon return. Examples include:

  • Interest income from out-of-state municipal bonds
  • Oregon does not recognize specific federal adjustments
  • Other state-specific additions listed on Schedule OR-ASC or OR-ASC-NP

Step 6: Subtractions from Income

Now subtract items Oregon does not tax. These might include:

  • Federal income tax paid (limited to $6,500 for 2016)
  • Social Security benefits
  • Oregon 529 College Savings Plan contributions
  • Medical expenses (for taxpayers age 64 or older)
  • Other allowable subtractions are listed on the adjustment schedules

Step 7: Calculate Oregon Taxable Income

Your Oregon taxable income results from your federal AGI plus additions, minus subtractions, and applicable deductions. This is the amount you’ll use to determine your state tax liability.

Step 8: Choose Standard or Itemized Deductions

Oregon allows you to claim either:

  • A standard deduction (amount depends on filing status), or
  • Itemized deductions based on your federal Schedule A, minus any Oregon state income tax you included.

Be sure to choose the method that gives you the greater tax benefit.

Step 9: Calculate Tax Using Tables or Rates

Use the tax tables or rate charts in the official instructions to calculate your tax due. Oregon’s income tax system is progressive, so the rate increases as your income rises.

Step 10: Apply Available Tax Credits

Credits reduce the amount of tax you owe. Some common 2016 credits include:

  • Personal exemption credit
  • Retirement income credit
  • Credit for income taxes paid to other states
  • Working Family Household and Dependent Care credit

Details on each credit can be found on the Department of Revenue website or the applicable instruction page.

Step 11: Report Payments and Withholding

Include all Oregon income tax withheld as shown on your W-2s and 1099s. Also, enter any estimated payments or overpayments carried forward from prior years.

Step 12: Determine Refund or Amount Owed

After subtracting payments and credits from your calculated tax, you’ll know whether you’re due a refund or owe additional tax.

Double-Check Before Filing

Before submitting your return, review and verify every entry for accuracy. Common issues include math errors, missing Social Security numbers, unsigned forms, or incorrect deductions.

Include all required supporting documentation:

  • Copy of your federal return (front and back)
  • W-2s and 1099s with Oregon tax withheld
  • All completed Oregon schedules (e.g., OR-ASC)
  • Any documentation for deductions, such as retirement account contributions or medical expense records

Being thorough can help prevent delays in processing or receiving your refund.

Filing Methods: How to Submit Your Oregon Return

Once you’ve completed your 2016 Oregon tax return, the next step is choosing how to submit it. Oregon offers different filing methods, each with benefits depending on your situation.

Electronic Filing (E-file)

E-filing is the fastest and most efficient way to file your return. You can file electronically using:

  • Commercial tax preparation software
  • A tax professional
  • The IRS Free File system (for eligible taxpayers)

Many Oregon taxpayers qualify to file electronically for free through these tools. E-filing also reduces the chance of errors, confirms that your return was received, and helps you get your refund faster—especially if you choose direct deposit.

Paper Filing by Mail

If you prefer to file a paper return, make sure to:

  • Use black or blue ink (not pencil or red ink)
  • Include all required forms and schedules
  • Attach a copy of your federal return (front and back)
  • Sign the return
  • Include payment if you owe tax

Use the correct mailing address:

  • With a payment:
    Oregon Department of Revenue
    PO Box 14555
    Salem, OR 97309-0940
  • Without a payment:
    Oregon Department of Revenue
    PO Box 14700
    Salem, OR 97309-0930

2-D Barcode Filing

If you use tax software to prepare your return but don’t e-file, the printout will include a 2-D barcode. This helps the Department of Revenue scan and process your return more efficiently.

Filing Centers and Authorized Agents

Some taxpayers prefer in-person help. Oregon has local tax assistance centers and works with authorized agents to help process returns. Check the Department of Revenue’s website for up-to-date hours and service locations.

When to File

The original deadline to submit your 2016 Oregon return was April 18, 2017. If you're filing late, send your return as soon as possible to reduce penalties and interest.

Even though the due date has passed, if you’re owed a refund, you can still claim it by filing within three years of the original deadline.

How to Make a Payment (or Set Up a Plan)

You must pay the Oregon Department of Revenue if you owe taxes on your 2016 Oregon return. Several options are available to help you pay securely and on time.

Payment Methods

1. Electronic Payment

You can pay directly from your checking or savings account using Revenue Online:

This method is free, available 24/7, and confirms your records.

2. Credit or Debit Card

Payments can also be made using Visa, MasterCard, Discover, or American Express:

  • Use Revenue Online or call 1-888-972-9673
  • A small convenience fee may apply

3. Check or Money Order

If mailing a payment:

  • Make your check payable to the Oregon Department of Revenue
  • Write “2016 Income Tax” and the last four digits of your Social Security number on the check
  • Include Form OR-40-V (the payment voucher)
  • Mail to:
    Oregon Department of Revenue
    PO Box 14555
    Salem, OR 97309-0940

Do not send cash. Be sure your envelope has proper postage and is mailed by the due date.

If You Can't Pay in Full

If you cannot pay the full amount you owe, it’s still best to submit what you can by April 18, 2017. This reduces interest and penalties.

Once you receive a billing notice, you can request a payment plan through Revenue Online. Oregon will work with you to set up monthly payments based on your situation.

Penalties and Interest

Failure to pay on time leads to additional charges:

  • Interest: Begins accruing on unpaid taxes the day after the deadline
  • Late payment penalty: 5% of the unpaid balance
  • Late filing penalty: 20% if your return is more than three months late

Paying even part of your bill by the deadline can reduce what you owe after tax penalties and interest are applied.

Tracking Refunds and Balances: What Happens After You File

After submitting your 2016 Oregon tax return, you can track your refund or check if there’s any balance due through the state’s online system. It’s a good idea to monitor your account activity, especially if you’re expecting a refund or have made a payment arrangement.

Checking Your Refund Status

The fastest way to check your refund is through Revenue Online:

  • Go to oregon.gov/dor
  • Click Revenue Online
  • Select “Where’s My Refund?”
  • Enter your Social Security number, filing status, and expected refund amount

You can also call:

  • 1-800-356-4222 (toll-free from Oregon)
  • 503-378-4988 (outside Oregon or within Salem)

Refunds sent via direct deposit typically arrive within 7–10 days of filing electronically. Paper check refunds or returns filed by mail can take 3–4 weeks. Processing times may increase if your return is selected for review, has errors, or is incomplete.

Why Refunds May Be Delayed

  • Your return was selected for manual review
  • You filed a paper return
  • You requested a check rather than direct deposit
  • You owe debts to other agencies or governments
  • There are math errors or missing information

Checking Account Balances

To see if you owe anything or to verify a payment was applied:

  • Log in to Revenue Online
  • View your account status and transaction history

If your refund is applied to existing balances, it will appear there. For example, if you have unpaid interest or penalties from past years, part of your refund may cover those before the rest is issued.

Common Mistakes to Avoid When Filing

Even experienced filers can make mistakes when preparing a state return. These errors often lead to processing delays, rejected forms, or unexpected tax bills. Understanding what to avoid can save time and help you stay in line with Oregon’s tax regulations.

1. Missing or Incomplete Federal Return

Your Oregon return must include a complete copy of your federal return, including all pages. Failing to attach this is one of the most common reasons for delay.

2. Using the Wrong Form

Oregon has different forms for full-year residents, part-year residents, and nonresidents. If you moved during the year, select the correct version. Choosing the wrong form may cause issues with how your income is taxed.

3. Not Reporting Oregon-Source Income

Part-year residents or nonresidents must report Oregon-source income. This includes earnings from rental property, a business based in Oregon, or the sale of real estate within the state—even if you no longer live there.

4. Omitting Investment or Capital Gains

Income from investing or capital gains, such as when you sell stock or land in Oregon, may be taxable. Even if federal rules provide an exception, Oregon may still tax it depending on how and where you earn it.

5. Not Double-Checking Deductions and Credits

Incorrect entries for credits or forgetting to apply for deductions can result in a higher tax bill. Before filing, visit the Oregon Department of Revenue site to confirm which credits or subtractions apply to your situation.

6. Forgetting to Sign or Date the Return

An unsigned return is not valid. If you’re filing jointly, both spouses must sign the return for it to be accepted by the state.

Final Filing Checklist for Individuals and Small Businesses

Before you submit your 2016 Oregon tax return, it’s worth going through a checklist to avoid missed items, rejected returns, or delays. Whether you’re filing as an individual or a registered small business owner, use this list to stay organized.

For All Individual Filers

  • Completed Return: Confirm that all income, deductions, and credits are correctly reported.
  • Federal Return: Include a complete copy of your Form 1040, 1040A, or 1040EZ.
  • Supporting Documents: Attach all W-2s and 1099s that show Oregon tax withheld.
  • Schedules and Forms: Include OR-ASC or OR-ASC-NP and any required
  • Oregon-specific schedules.
  • Signatures: Make sure the return is signed and dated. Joint filers must include both signatures.
  • Direct Deposit Info: Double-check bank routing and account numbers for direct deposit.
  • Correct Mailing Address: Use the correct address depending on whether you're sending a payment.

For Small Business Owners

  • Federal Schedule C: Required if you report income from self-employment or a sole proprietorship.
  • Form OR-65 or OR-20-S: File if you run a partnership or S corporation in Oregon.
  • Documented Transactions: If you had a sale of property or reported income from short-term rentals, keep detailed records.
  • Special Taxes: Remember that Oregon imposes specific taxes, such as the estate tax and the transient lodging tax, in some instances. These are separate from the income tax return but may apply depending on your activity.

For example, if you operated a short-term rental in Portland, the transient lodging tax likely applies, and local rates vary by jurisdiction.

  • Exceptions or Exemptions: Confirm whether any exception to filing or payment applies to your circumstances.

The Oregon Department of Revenue website offers printable resources and detailed instructions for most situations. Use these tools to avoid errors and file with confidence.

Frequently Asked Questions

Does Oregon have a sales tax or general sales tax?

Oregon does not impose a general sales tax on consumer goods or services. Unlike many other states, residents and visitors in Oregon typically do not pay sales tax when making retail purchases. However, certain local taxes may apply depending on the transaction type or location.

What is the transient lodging tax, x, and who needs to pay it?

The transient lodging tax applies to short-term stays in hotels, motels, vacation rentals, and similar accommodations. If you operate a rental property or manage bookings, you may be responsible for collecting and remitting this tax to the state or local authority. It is separate from your individual income tax return.

Am I subject to the Oregon estate tax if I inherit property?

Oregon has its estate tax, which applies when the total value of an estate exceeds a certain threshold (typically $1 million). The tax may be due if you inherit property and the estate is large enough. This is separate from any income tax you might owe on income the property generates afterward.

Do I still need to file in Oregon if I also paid taxes to other states?

You may still need to file in Oregon even if you lived or worked in other states. Oregon allows a credit for income taxes paid to another state, but you must report all Oregon-source income. Filing requirements vary based on residency status and income sources.

Is Oregon income tax different from a general sales tax?

Oregon uses a personal income tax system instead of a general sales tax. This means taxes are based on earnings rather than purchases. If you live or work in Oregon, your income tax filing is typically required even though you don’t pay sales tax on retail goods.
