W-2 Filing requirements

All businesses and all payroll service providers are required to report W-2 information electronically [
OAR 150-316.202(3)].

The Oregon Department of Revenue uses the same file specification for the W-2 information as the Social Security Administration with minor modifications to the state record.  Visit the Social Security Administration's website for more information about their EFW2 and EFW2C programs.

For Oregon file specifications and more information about iWire, go to the 2015 iWire file specifications for Form W-2.

The transmittal due date is March 31, 2016. We will only accept electronically filed W-2 information; paper W-2s or other forms of media are not accepted.

For additional information about filing information returns, see our FAQ and troubleshooting tips.

If you would like to contact us directly please e-mail us at iWire.DOR@oregon.gov or call us at (503) 945-8127.

1099 Filing requirements
Businesses with 11 or more of any one type of information return are required to report return information electronically (
OAR 150-314.360).

The Oregon Department of Revenue uses the Internal Revenue Service's (IRS) Publication 1220, with minor modifications to the state records. For Oregon specific file specifications, download Publication 1220 Addendum.

The transmittal due date is March 31, 2016. Forms 1099-MISC, 1099-G, 1099-R, and W-2G are filed electronically only; paper 1099s will not be accepted.

Payers issuing fewer than 11 information returns are not required to file 1099s either electronically or via paper. However, payers may file them electronically if they choose to.
