Answered August 2026

If you mailed Form 843, call the IRS at 800-829-1040 now because the IRS publishes no fixed FICA-claim processing time and its online return tracker is not described as a Form 843 tracker.

I applied for a FICA tax refund 6 months ago and haven't received it yet. How long does the IRS usually take to process these, and how can I check the status?

Summary

A six-month wait does not by itself mean your claim was denied. It is long enough to act now: the IRS recognizes six months as the point when a refund claimant may go to court if the agency has not decided the claim.

Your status route depends on what you actually submitted six months ago.

You mailed Form 843call now

This is the usual IRS claim route when an employer will not refund FICA withheld in error. Because the IRS tracker is described in terms of a tax return and does not list , call the IRS individual line at 800-829-1040 for the claim status.

You claimed a return credittrack online

If multiple employers together withheld Social Security tax above the annual limit, Publication 519 allows the excess as a credit on your income tax return. Track that return at using your SSN or ITIN, filing status, tax year, and exact refund amount.

You only asked your employernot at IRS

An employer request by itself is not an IRS claim to track. IRS Publication 519 says to ask the employer first; if you cannot get the full refund, file with the required support.

If the IRS has taken no action for six months, Publication 556 says a refund suit becomes legally available, but a phone inquiry and possible TAS escalation are the practical first steps.

Watch out for

No published processing promiseThe official IRS materials fetched do not give a normal completion time for a stand-alone FICA claim. Six months is nevertheless a meaningful point: IRS Publication 556 says you may file a refund suit once the IRS has not acted for six months, so you should escalate the status inquiry now rather than keep waiting without contact.
The online tracker may be the wrong toolThe IRS describes as tracking a return through Return Received, Refund Approved, and Refund Sent; it does not list stand-alone Form 843 claims. If you mailed Form 843, use the IRS individual phone line instead of treating an empty tracker result as a denial.
One employer and several employers use different routesIf one employer wrongly withheld or over-withheld Social Security or Medicare tax and will not correct it, the IRS route is Form 843. If several employers together withheld Social Security tax above the annual limit, IRS Publication 519 says to claim the credit on your income tax return; if any one employer alone withheld too much, ask that employer first and use Form 843 if it will not refund the excess.
A denial starts a court deadlineIf the IRS mails a , Publication 556 says the usual deadline to file a refund suit is two years from that mailing date. Court is optional and is not the ordinary status-check route, but do not ignore that notice or its date.

Next steps

These steps identify where your claim sits, use the correct tracker, and escalate the six-month delay in the right order.

First

Identify what you submitted

If your copy shows (often with Form 8316 for an eligible F, J, or M nonresident), follow the phone step. If the amount appears as excess Social Security tax on Form 1040 or 1040-NR, follow the online-tracker step. If you only asked your employer, there is not yet an IRS claim to track; Publication 519 says to file Form 843 if the employer will not provide the full refund.

Excess Social Security Tax

You can claim a credit for excess social security tax on your income tax return if you have more than one employer and the amount deducted from your combined wages for 2025 is more than $10,918.20. If any one employer deducted more than $10,918.20, you cannot claim a credit for that amount. Ask your employer to refund the excess. If your employer does not refund the excess, you can file a claim for refund using Form 843.
