When I first review an SFR, I do not expect every number to be wrong. Quite often, the W-2 matches down to the dollar, and the interest is right. The surprise is the bottom line. Payer reports gave the IRS a slice of the year, but not the facts I still need to ask about: business costs, the purchase price of investments, dependents, and filing status.
That is often how an IRS Substitute for Return begins. The agency is working from records supplied by employers, banks, brokers, and other payers. It has not sat down with the taxpayer, reviewed the household, or reconstructed a business. Before paying the amount on the letter, find out whether the IRS is still proposing the tax or has already assessed it. The notice number will usually tell you where the case stands.
Quick Answer: The IRS Filed a Return for Me—What Should I Do?
If the IRS filed a return for you, read the notice before sending a payment or another tax form. CP2566 usually presents a proposed calculation. CP3219N is a Notice of Deficiency with a Tax Court deadline. Once the IRS has assessed the SFR, the correction is handled differently. When a return was required, the taxpayer normally files the missing original return—not Form 1040-X—and the IRS reviews whether the assessment should be changed.
| Notice or stage | What it generally means | Immediate priority |
|---|---|---|
| CP59 | The IRS says a return is missing | File the return or explain why no return was required |
| CP2566 | The IRS has proposed a calculation | Compare the proposal with the records and respond by the notice date |
| CP3219N | The IRS issued a Notice of Deficiency | Protect the 90- or 150-day Tax Court deadline |
| SFR already assessed | The balance has entered the account and may be in collection | File the original delinquent return and address collection deadlines separately |
What Is an IRS Substitute for Return?
Internal Revenue Code Section 6020(b) permits the IRS to prepare a return when a required return has not been filed. The result is called a Substitute for Return, commonly shortened to SFR. Cases produced by the automated non-filer program are also referred to as ASFR cases.
What is actually in the government file? Usually, it is a collection of forms: W-2s, 1099s, withholding entries, retirement distributions, and investment-sale reports. The SFR is built from those forms. It is not the product of a conversation with the taxpayer or a review of the taxpayer’s books.
The IRS may have no reliable way to identify business costs, missing investment basis, dependents, a more favorable filing status, or credits that require taxpayer information. An American living overseas may need to claim a foreign tax credit or another international provision that cannot be determined from an ordinary income report. That missing information is why the SFR balance deserves a careful review.
Start With the Number Printed on the Notice
People often use “SFR” to describe the entire non-filers process. In practice, there is a major difference between a return the IRS is discussing, a proposed deficiency, and tax that has been formally assessed.
CP59: The IRS Says a Return Is Missing
CP59 is an early non-filers notice. It does not mean that the IRS has completed an SFR assessment. The notice asks for the return or an explanation of why no return was required. A taxpayer who receives it still has an opportunity to address the missing year before the case proceeds further in the SFR process.
CP2566: The IRS Has Calculated a Proposed Amount
CP2566 shows tax, penalties, and interest calculated from information available to the IRS. Read the response form as closely as the dollar amount. It identifies the year in question, the response date, and the address to which the reply must be sent.
CP3219N: The Statutory Deadline Has Arrived
CP3219N is the non-filer Notice of Deficiency. It usually gives the taxpayer 90 days from the date on the notice to petition the U.S. Tax Court. The period is generally 150 days when the notice is addressed to a person outside the United States. The IRS cannot extend that statutory deadline.
A taxpayer who disagrees may be able to file the missing return by the response date. A Tax Court petition may also need consideration. Waiting until day 91 can eliminate an important way to contest the tax before payment.
After the Assessment
Once the deficiency window closes, the case takes on a different character. The IRS may assess its calculation and begin sending collection letters. At that point, “please file” and “please pay” occur simultaneously.
Why the IRS Number May Be Wrong
Information returns usually show amounts paid to or received by the taxpayer. They often do not show all the deductions, cost basis, household facts, and credits needed to calculate the final tax.
Picture a roofer whose 1099s total $143,700. That is the number in the IRS file. Back in his office are receipts for shingles, flashing, dump charges, insurance, a helper’s pay, and one costly compressor repair. Whether every item is deductible depends on the records and the tax rules. But ignoring the entire expense side treats receipts as profit, which can severely distort Schedule C.
Investment accounts produce a different problem. A Form 1099-B may report the sale proceeds while cost basis is missing or incomplete. Tax on the proceeds is not the same as tax on the gain. The purchase records may considerably affect the result.
Don’t treat the W-2 as the whole tax file. It won’t show whether a child qualifies as a dependent or whether college expenses belong on the return. Estimated payments deserve a closer look, too. The taxpayer may have made the payment, but the IRS could have credited it to a different year.
I also would not tell a taxpayer that the balance is certain to drop. The bookkeeping may turn up additional income. Until the year is actually prepared, there is no honest way to know the result.
Can You File Your Own Return After an SFR?
Yes, in most cases, the taxpayer may still file the return originally due. The IRS states that it will generally adjust the account when the taxpayer’s return establishes the correct figures.
Tax professionals sometimes refer to this as “filing over an SFR.” After the IRS has made the assessment, its procedural term is SFR reconsideration. Neither phrase automatically requires the taxpayer to prepare an amended return. Form 1040-X changes an original return previously filed by the taxpayer. In the ordinary SFR case, the taxpayer never filed that original return.
The delinquent original return is processed differently from an amendment and may be examined when it includes items the IRS could not verify.
Before Preparing the Return, Confirm the Filing Requirement
First confirm that a return was required. Check for a mistyped Social Security number, a duplicate form, and the filing threshold that applied to this taxpayer in that year.
If no return was required, the better response may be a written explanation with supporting documents. Filing an unnecessary return to answer a notice can create a different set of problems.
Rebuilding the Missing Year
I normally pull two transcripts. The wage and income transcript becomes my checklist for W-2s, 1099s, and other payer reports. I read the account transcript chronologically. It shows assessments, credits, payments, reversals, and adjustments—essentially, the IRS history of that tax year.
Next, turn to records the IRS does not have: bank statements, brokerage confirmations, prior depreciation schedules, and corrected payer forms. Document how any reconstructed figure was reached; a convenient round estimate is not a workpaper. Use that year’s forms, then reconcile the result against the wage and income transcript.
Where Should the Return Be Sent?
The address on a current CP2566 or CP3219N should not be replaced with an address found in an old article or a general filing chart. Follow the response instructions printed on the taxpayer’s notice.
Then watch the account. Delivery does not prove that the return was accepted or the tax changed. Look for the revised figures on the transcript.
What If the Correct Return Still Shows Tax Due?
File it anyway. A taxpayer does not solve an inability to pay by leaving an inflated or uncertain assessment in place.
Match the corrected balance to the taxpayer’s finances:
- Affordable monthly cash flow may support an installment agreement.
- An Offer in Compromise requires analysis of equity, future income, and the time left to collect.
- A household unable to cover necessary living costs may qualify for Currently Not Collectible treatment.
Currently Not Collectible status pauses active collection; it does not erase the debt. Penalties and interest may continue accruing, and the IRS may review the taxpayer’s finances later.
The label is less important than the math behind it. The IRS will consider income, allowable living expenses, property, filing compliance, and the time remaining to collect. First correct the tax. Then use the financial record—not guesswork—to choose the collection route.
What Happens to Penalties and Interest?
Correcting the underlying tax should also correct charges calculated from that tax. It does not, however, make a late return timely. The ordinary starting rates are:
- Failure to file: 5% of unpaid tax for each month or part of a month, with a 25% ceiling.
- Failure to pay: 0.5% per month, also limited to 25%.
The two charges may overlap for a given month, and coordination rules change the arithmetic. After the account is adjusted, check the revised penalty figures rather than assuming the computer handled all downstream changes.
Penalty relief is a separate request. Administrative relief may be available in some cases; other taxpayers may be able to document reasonable cause. Interest is harder. It generally continues on tax that was not paid when due.
An SFR Involves Three Different Clocks
The assessment period, collection period, and refund period are often conflated, even though each addresses a different question.
An IRS-prepared SFR does not start the ordinary three-year period for assessing additional tax. A later valid return generally starts it.
The usual ten-year collection period starts with assessment, not the return’s due date. Suspensions can alter it, and tax assessed later may carry a different expiration date. Review the transcript before calculating the deadline.
Refunds follow a separate deadline. A claim generally must be filed within three years after the return was filed or two years after the tax was paid, whichever is later. Lookback rules can still limit the amount available for refund. Because withholding and estimated tax payments are generally treated as paid on the return’s original due date, the IRS may accept an old delinquent return even when some or all of the refund is no longer available.
U.S. Taxpayers Living Abroad
An SFR can be particularly misleading for an American living overseas. Foreign wages may appear in IRS files without the information needed to determine a Foreign Tax Credit, Foreign Earned Income Exclusion, foreign housing amount, or treaty-based position. Those provisions have separate eligibility and filing requirements; they are not automatically added to an IRS calculation.
When CP3219N is addressed to a person outside the United States, the petition period is generally 150 days instead of 90. The date printed on the notice still controls.
New York Requires a Separate Review
Correcting a federal SFR does not automatically file or correct a New York return. A New York taxpayer may still need to file an original or amended state return, and a federal adjustment may not flow through immediately. Compare the two accounts, identify any missing state returns, and follow the instructions in the New York notice.
When Does an SFR Case Need Professional Help?
A wage-only return with good records may not require representation. Several missing years, reconstructed books, absent investment basis, foreign income, or an expiring CP3219N make the work harder.
Help may also be warranted after collection begins. Bankruptcy, a deceased taxpayer, disputed marital status, identity theft, and possible willful nonfiling add issues beyond return preparation.
IRS Substitute for Return FAQs
The IRS prepared a tax calculation from the information it had. That calculation can support an assessment, but it may not include facts that would appear on a return prepared from your records.
CP2566 normally presents a proposed amount and gives response instructions. Ignoring it can lead to CP3219N and a formal assessment.
The usual Tax Court petition period is 90 days from the notice date. It is generally 150 days for a person outside the United States. The IRS cannot extend the statutory deadline.
Usually, no. If the taxpayer never filed the original return, the normal response is the missing Form 1040 for that year, not Form 1040-X. Account history can create exceptions, so verify what the IRS has on file first.
No automatic stop applies merely because a return was mailed. Follow the deadline on any levy or hearing notice while the SFR correction is being processed.
Paying may make the current bill go away. It does not answer whether the bill was correct. Compare the SFR with a properly prepared return first, especially when credits, a state filing, or a possible future bankruptcy analysis may be affected.
