A mortgage lender asks for your "tax transcript." You pull the tax return transcript and send it. Six months later the IRS sends you a bill for the same year, and you are confused, because the transcript showed a refund.

Nothing was wrong with the transcript. It did exactly what it is designed to do: show the original return. It was never designed to show what happened next.

What the tax return transcript contains

IRM 21.2.3.2.1 describes the tax return transcript as containing "significant data transcribed from the original return." The list of items includes the type of return, filing status, tax shown on the return, adjusted gross income, taxable income, withholding, earned income credit, self-employment income and tax, tax due or refund per return, refundable credits, total income, business expenses and wages paid.

Then the IRM states the limitation plainly: tax return transcripts "will not show amendments or adjustments made to the account after the original return has posted." If adjustments were made, the IRM directs employees to offer the record of account instead.

There are display quirks worth knowing. The IRM notes that the transcript is programmed to show only four dependents, so a family with five children may think the preparer dropped one. It also notes that only up to three Schedule Cs are transcribed; when there are more, the remaining ones are consolidated so the totals are complete.

Per return vs. per computer

This is the most useful line-level feature on the return transcript, and most people skip right past it.

The IRM explains that the IRS sometimes changes the taxpayer's reported figures during processing "due to input errors, incomplete or missing information, or computational errors." When that happens, the tax return transcript shows both: the taxpayer's original figure labeled "per return," and the IRS's corrected figure labeled "per computer."

So if you see two numbers for the same line, the IRS changed it when the return posted. That is usually a math error or processing correction, not an audit. Document 6209's freeze code table describes a condition set by "posting of an original return which contains a math error code." Freeze codes are internal alpha codes, not transaction lines, so the per return and per computer split is the place a taxpayer can actually see that a processing change happened.

Why it matters: a math error correction is assessed differently from an exam deficiency, and your response options are different. Knowing which one you are dealing with tells you which rules to read next.

What the record of account adds

IRM 21.2.3.2.3 says the record of account transcript "combines the information from the tax account and tax return transcripts." The IRM also says why people request it: account changes occurred after the original return was processed, such as amendments and subsequent payments.

In practice, the record of account gives you the original return data plus the full transaction history from the account transcript. That means you see the TC 150 with the original tax, any TC 290 additional assessment from an adjustment, any TC 300 assessment from an exam, any TC 291 or TC 301 abatement, every payment and every refund.

Amended returns are where people get burned

Say you filed an amended return. The tax return transcript will still show the original numbers. The IRM is explicit about that for individual returns.

On the account side, Document 6209 says an amended return posts as TC 977, and that "an amount posted with TC 977 is a remittance amount and does not reflect adjustment in liability." The actual change in tax, if the IRS accepts the amendment, posts later as a TC 29X or TC 30X transaction. So an amended return can be sitting on the account with no change to the tax yet. That distinction is the subject of TC 977 and TC 976.

There is one exception noted in the IRM on the business side: the newer Form 94X series transcripts for employment tax returns do display adjustments from amended returns. For the Form 1040, the rule stands. The return transcript is the original return, full stop.

Business return transcripts

The IRM lists the business returns covered by the standard tax return transcript: Form 1065, Form 1120, Form 1120-H, Form 1120-L and Form 1120-S. It also describes seven newer business return transcripts funded under the Inflation Reduction Act: Forms 940, 941, 943, 944, 945, 990-T and 1041. Those newer transcripts are masked, and the Form 94X series versions show adjustments from amended returns, which the individual return transcript does not.

If you are trying to reconcile a payroll tax balance, that difference is useful. The 94X return transcript can show the amended figures; the account transcript shows the assessments and payments. Read them together, the same way you would read an individual record of account.

A simple comparison routine

When I have both documents for an individual year, I do three checks.

  • Tax per return on the return transcript against the TC 150 amount on the account. They should line up, allowing for how credits are presented. If they do not, find the processing change.
  • Every per computer figure on the return transcript. Each one is a change the IRS made when the return posted, and each one needs an explanation.
  • Every later assessment on the account, such as a TC 290 or TC 300. None of these appear on the return transcript, and they are usually why the bill does not match the return. See TC 300: Examination Assessments.

If all three checks come out clean, the year probably is what it looks like. If any of them does not, you have found the place to start asking questions.

Masked transcripts

Since September 2018 for individuals and December 2020 for businesses, the IRS has produced masked transcripts that remove or shorten personally identifiable information. Per IRM 21.2.3.3, some PII, such as city, state and ZIP code, is removed entirely, and other items, such as the SSN or EIN, are shortened to the last four digits. Financial amounts are shown in full.

Masking does not change the numbers. It changes how easily a third party can match the transcript to you. The IRM notes an optional Customer File Number field that a third party can supply to help associate a masked transcript with the right customer.

The verification of non-filing letter is not a transcript of anything

One more product causes confusion. IRM 21.2.3.2.5 describes the verification of non-filing letter as confirming that the IRS has no record of a processed individual return for the period at that time. The IRM adds a sentence people should read twice: "This letter does not provide any status of the taxpayer's filing requirement."

In other words, the letter says the IRS has not processed a return. It does not say you were not required to file one. If you need to know whether the IRS thinks a return is missing, the account transcript and its delinquency codes are the better source.

Which one should you pull?

One more practical point. People often order one product, find it confusing, and assume the IRS records are wrong. Before you reach that conclusion, ask whether you are holding the right document for the question. A return transcript that shows a refund and an account that shows a balance due can both be correct at the same time. The return transcript is frozen at the moment the original return posted. The account kept moving. Exams, underreporter adjustments, math corrections, offsets to other years and penalties all happen on the account, and none of them rewrite the original return data.

If you are representing yourself in any dispute with the IRS, keep a copy of each product you pull with the date you pulled it. The account changes week to week as cycles post. A dated copy lets you show what the IRS's own records said at a particular time, which matters when you are arguing about when something happened.

For a loan application, the lender will tell you which one it wants, and it usually wants the return transcript. For understanding your own case, the record of account or the account transcript is the document that tells the truth about where the year stands now. Read the return transcript for what you said. Read the account for what happened.
