Where to Mail Your Oregon Tax Return: Addresses and Instructions

Filing your Oregon tax return accurately and on time is crucial to avoid penalties or delays in processing. Knowing the correct mailing address for your specific type of return ensures it reaches the appropriate department efficiently, streamlining the tax filing process.

Approved Mailing Addresses

Selecting the correct address when mailing your Oregon tax return is essential to avoid delays. The Oregon Department of Revenue has designated specific addresses based on the type of return and whether a payment is included. For individual income tax returns without a payment, send to: Oregon Department of Revenue, PO Box 14700, Salem, OR 97309-0930. If including a payment, use: Oregon Department of Revenue, PO Box 14555, Salem, OR 97309-0940. Sending documents to the wrong address can result in processing delays and penalties.

For business tax returns, the address depends on the business entity and return type. Corporate excise tax returns should be sent to: Oregon Department of Revenue, PO Box 14790, Salem, OR 97309-0470. If a payment is included, use: Oregon Department of Revenue, PO Box 14777, Salem, OR 97309-0960. These specific addresses ensure business-related tax documents are handled efficiently.

Additional Documents to Include

Filing your Oregon tax return requires more than completing forms. Individual filers should attach copies of federal W-2 forms, which report wages and tax withholdings, and any 1099 forms that reflect additional income, such as freelance work or investments. These documents ensure accurate income reporting and tax calculations.

Business entities must include different supporting documents. Corporations should attach a copy of their federal tax return, IRS Form 1120, to ensure consistency between federal and state filings. Partnerships need to include IRS Form 1065 and any Schedule K-1s issued to partners. These documents help verify reported figures and facilitate the review process.

Confirming Delivery

After preparing and mailing your Oregon tax return, confirming its delivery is essential. Using certified mail with a return receipt provides proof of delivery and peace of mind that your documents have reached the Oregon Department of Revenue.

Private courier services like UPS or FedEx also offer tracking and delivery confirmations. These services are particularly helpful if filing close to the deadline and needing expedited delivery. While more expensive than standard postal services, they provide added assurance and help avoid late filing penalties.
