TC 806: Withholding Credits and Why They Do Not Always Match Your W-2

For most wage earners, the biggest credit on the account is not a check they wrote. It is the federal income tax withheld from their paychecks. On the transcript, that is a TC 806. When it is wrong, the whole year is wrong.

The definition

Document 6209 titles TC 806 "Credit for Withheld Taxes and Excess FICA" and says it "credits the tax module for the amount of withholding taxes and excess FICA claimed on a Form 1040 or 1041 return." It "may also be generated by appropriate line adjustment on an Examination or DP Tax Adjustment."

Note the word claimed. The TC 806 reflects the withholding you claimed on the return, as processed. It is not pulled directly from the W-2s. That is the root of most withholding disputes.

Its reversal is TC 807, "Reversed Credit for Withheld Taxes," which "reverses the TC 800 or 806 credits in whole or in part by posting a debit to the tax module" and is generated from the appropriate line adjustment of an examination or data processing adjustment. TC 800 is the manually prepared version of the withholding credit, and TC 802 corrects a TC 800 processed in error.

Comparing TC 806 to the wage and income transcript

The wage and income transcript shows federal income tax withholding by document, as each payer reported it. IRM 21.2.3.2.4 lists federal income tax withholding among the data it displays. It does not show state or local withholding.

Add up the federal withholding on every W-2 and 1099 on the wage and income transcript. Compare that to the TC 806 on the account. Three outcomes are possible.

• They match. Good. Withholding is not the problem.
• The TC 806 is higher than the payer data. The return claimed more withholding than payers reported. Expect the IRS to question it.
• The TC 806 is lower than the payer data. The return may have missed a W-2 or 1099 with withholding. That is money you paid and did not claim.

The first mismatch is the dangerous one. A return that claims withholding payers did not report is exactly the kind of discrepancy the IRS review programs described below are built to catch. The second is the one people miss, and it is usually a straightforward claim, subject to the refund statute in IRC 6511.

Remember the IRM's caution: the wage and income transcript shows only information returns filed with the IRS, which may not be every document issued to you. A missing W-2 on the transcript does not prove the withholding was not taken from your pay. Your pay stubs and the W-2 itself are the evidence. See Account Transcript vs. Wage and Income Transcript.

How the IRS reverses withholding

When the IRS disagrees with claimed withholding, the reversal posts as TC 807. It can come from several directions.

From the underreporter program. Document 6209's underreporter process code tables include a pre-notice closure described as an adjustment using TC 29X with reference numbers 806 and 807 for withholding discrepancies. The reference numbers point to the withholding credit lines. If your transcript shows TC 922 activity followed by a TC 807, the matching program reduced your withholding credit. See TC 922 and the Underreporter Program.

From a credit review. Document 6209 lists TC 971 action code 140 for cases selected by the Automated Questionable Credit unit due to "potential non-compliant withholding or refundable credit," with the refund frozen until the review is complete. A TC 570 hold often travels with it. If the review concludes the withholding was overstated, a TC 807 and an adjusted refund follow.

From an examination. An exam that disallows withholding posts the reversal through the exam adjustment, with the generated TC 807 reflecting the line change.

A worked comparison

The account credited 600 dollars less than payers reported. The most likely explanation is that the return left off the 1099-R withholding. That 600 dollars was taken from the distribution and sent to the IRS on the taxpayer's behalf, and the return never claimed it. Fixing it is an amended return or claim, filed within the IRC 6511 period.

Run the same comparison the other way, too. If the TC 806 had been 6,550, the return would have claimed 600 dollars more than payers reported, and the taxpayer should expect a question.

What the TC 806 does not include

State and local withholding never appear here. The wage and income transcript does not show them either, per the IRM. Social Security and Medicare tax withheld from wages is not an income tax credit, except to the extent of excess FICA claimed on the return, which the TC 806 title expressly includes. Estimated tax payments are not withholding; they post as TC 660. Payments with the return are TC 610. Keep the categories separate and the math gets easier.

When withholding counts as paid

Timing matters for refund claims. IRC 6513(b)(1) says tax actually deducted and withheld at the source during a calendar year is deemed paid by the recipient "on the 15th day of the fourth month following the close of his taxable year." For a calendar-year individual, that is April 15 of the following year.

Why that matters: IRC 6511(b)(2) limits a refund to the tax paid within a lookback period before the claim. Because withholding is deemed paid on the return due date, even if it came out of your pay a year earlier, the deemed date is what you measure from. If you are filing a late return to claim back withholding, count from that date, not from the paycheck dates.

The same section treats estimated tax payments as paid on the last day prescribed for filing the return, determined without regard to extensions, under IRC 6513(b)(2).

Excess Social Security tax

The TC 806 title includes excess FICA. If you worked for more than one employer and too much Social Security tax was withheld in total, the excess claimed on the return is credited through the same code. Document 6209's credit reference numbers also include 252, "Excess Social Security or Railroad Retirement taxes withheld," used in adjustments. If a claim for excess Social Security tax is disallowed, the reversal posts the same way as any other withholding reversal.

Withholding compliance codes

If the IRS believes your withholding is too low going forward, it can tell your employer how much to withhold. Document 6209 lists TC 971 action codes for that program: 146, "Withholding Lock-in Letter sent," 147, "Withholding Compliance (WHC) transcript created," and 148, "Withholding Lock-in modification."

Those codes do not change the year they post on. They are about your future paychecks. But if you see them, the IRS has noticed a pattern of under-withholding, and that pattern usually shows up on the account as balance due years.

A practical review

• Total the federal withholding from the wage and income transcript.
• Compare it to the TC 806 on the account transcript.
• Check for a TC 807 and match it to a notice.
• If withholding was under-claimed, consider a claim within the IRC 6511 period, measured from the deemed payment date under IRC 6513(b)(1).
• If withholding was over-claimed, fix it before the IRS does, and understand that interest and penalties may follow.

Keep your last pay stub for each job and every W-2 and 1099 you received. If the IRS's records and yours disagree, those documents are the evidence that settles it, and the IRS will ask for them.

Withholding is your money. The transcript tells you whether the IRS has given you credit for all of it, and no more.
