You must withhold Oregon tax from all wages paid to
employees who are residents of Oregon, including any wages earned
outside of Oregon. Employers who pay wages to Oregon residents may be
relieved of the duty to withhold if it can be shown to the satisfaction
of the department that each employee will receive $300 or less from the

amount for their filing status. Nonresident employees with wages greater
than their standard deduction amount are required to file an Oregon
nonresident return. The standard deduction changes each year.
Note: Nonresident employees may earn
less then their standard deduction, but still request withholding
because they have additional Oregon income.

employees working in Oregon. However, we do ask employers to register
and withhold taxes as a convenience to the employee.

agree. You must fill out the Combined Employer's Registration and the
employee must complete federal Form W-4 (Employee's Withholding

As an Employer, you are required to submit form WR
(Oregon Withholding Annual Reconciliation Report) to reconcile the
information you previously submitted throughout the year. You will need
to report the actual amount of withholding on your employee's W2/1099s.
2. I correctly filed form OQ for all four quarters. Is it still necessary to file form WR as well?
Yes. Like the federal form W3, form WR verifies the
actual withholding reported and matches that information with the
quarterly reports (form OQ).
Form WR is due by February 28. If submitting W2s
electronically, you can submit form WR by the extended due date of March
31. However, if you stop business anytime during the year, form WR is
due within 30 days after your final payroll.
4. If I file my withholding using form WA (Oregon Annual Agricultural Report)? Do I need to submit form WR also?
Yes. Even though you file an annual return, you're still required to submit form WR.

Yes. Even though you file an annual return, you're still required to submit form WR.
6. I'm required to submit my W2s electronically. Do I still need to file form WR?
7. Is it necessary for an owner/officer to sign form WR?
No. However, the person completing and signing form WR must be able to provide additional information.
8. When completing boxes 1 through 4 on form
WR, do I include Employment and WBF payments, as well as my quarterly
No, boxes 1 through 4 should only have the tax actually reported on form OQ for withholding each quarter. You then enter the total in box 5.
9. Isn't the amount I put in box 5 the same as box 6?
Not necessarily. Box 5 is the total withholding reported on your OQ, WA, or OA reports for the year. Line 6 is the ACTUAL amount of withholding you reported on all W2/1009s issued to your employees. These numbers may not always be the same.
10. Do I need to send my W2/1099s with form WR?
No, but you will need to keep them on file in case we ask for them later.
11. I don't have four quarters to report because I file form WA (or OA), how do I fill out lines 1 - 4?
Take the annual amount reported on form WA (or OA) and insert that number on line 4 of form WR.
12. What if there's a difference between what I filed on form OQ (line 5) and the W2/1099s (line 6)?
Report any difference between line 5 (total withholding tax reported) and line 6 (total tax shown on the W2s or 1099s) on line 7. If line 6 is larger than line 5, you will owe additional tax. If line 6 is smaller than
line 5, you've overpaid and will have a credit balance. Please provide a
detailed explanation of the differences below line 7.
13. I've discovered an error after I submitted form WR. How do I make a correction?
Make corrections on a copy of your previously submitted form WR. Write "Amended"
across the top in blue or black ink. Explain the reason for the
correction on line 7. Include any amended OQs for each quarter you are
correcting and mail these together with the amended form WR.
14. Do I need to submit any substantiation for the change?
Yes, you'll need to substantiate changes if you're
reporting a significant change on form WR or are requesting a large
refund due to errors that occurred during the year. Your refund request
may be delayed if a sustantiation is not submitted.
15. What type of substantiation or documentation should be included?
Substantiation should include such information as:
A detailed explanation on line 7.
W2C and/or W3 transmittals showing the correct
information reported to the IRS for state withholding taxes.
Company reconciliation reports (other than the W3
transmittal) verifying what had been reported to the IRS for Oregon
If withholding was corrected because an employee relocated, send a record of when that occurred.
W4 showing the corrected number of allowances claimed.
Any other substantiation that verifies the changes being reported on form WR.
16. We merged several companies last year. IRS
allows that all W2 information can be reported under the successor
company and reported under one FEIN. How do we correctly complete form
Form WRs should be completed for each BIN (Business
Identification Number) involved in the merger, even though all W-2s are
being reported under the successor companies' FEIN/BIN to allow for the
correct reconciliation of accounts.
If not possible, send an explanation with the following:
When the merger took place.
A list of the companies involved in the merger, including their BINs.
