IRS says W-2 “not received,” claims $0 federal withholding, now demanding double — employer already filed W-2 via Paycor. What should I do before hiring an attorney?

Hi everyone — I’m looking for guidance on next steps with an IRS issue that seems to be caused by missing/incorrect wage & withholding data on the IRS side.

Situation:

  • The IRS is claiming they never received my W-2 for a prior tax year and is now demanding about 2x what we already paid for that year.

  • The W-2 was filed by the employer through Paycor (employer says it was submitted as required).

  • We also mailed our return with a complete Form 1040 and the W-2 attached.

  • The IRS first claimed they never received the original filing, but we have USPS tracking proof showing delivery.

  • We then mailed a second identical copy of the same return (again with tracking), also delivered.

  • The IRS appears to have entered the return incorrectly and is treating it as if we had $0 federal withholding, even though the 1040 clearly reflects roughly $30,000 already paid/withheld.

  • They have now seized our most recent year’s refund to offset the balance they say we owe.

  • Based on our records, the IRS actually owes us roughly $10,000 across the two years once the W-2/withholding is properly credited.

Problem:

  • The IRS is refusing to accept another copy of the W-2 from us and says it must come directly from the employer.

  • The employer says it was already sent via Paycor.

  • I’ve gone to the local IRS office twice and spent 10+ hours on the phone, with no resolution.

  • The IRS tax transcript doesn't show a W2. I'd does show they made a revision, because at one point it showed we were owed a refund.

Questions:

  1. What is the most effective way to get the IRS to properly post the W-2 and federal withholding (or correct their data entry error)?

  2. Is there a recommended process to have the employer/Paycor re-file or re-transmit the W-2 if the IRS insists it’s missing?

  3. Given they already offset our refund, should I contact the Taxpayer Advocate Service (TAS), and what qualifies as “economic hardship” or urgency?

  4. At what point does it make sense to involve a tax attorney or enrolled agent, and is there anything I should do first that typically resolves this faster?

I can provide redacted copies of notices and dates if needed. Thank you for any guidance.
