When someone does not file, the IRS can prepare an IRS substitute for return, often called an SFR, using wage and income reports it receives from employers, banks and brokers. The result is a tax bill built without your deductions, credits or expenses. In many cases an original return can still be filed to replace the SFR, which may reduce the balance.

What an IRS Substitute for Return Actually Is
Federal tax law allows the IRS to prepare a return when a taxpayer fails to file one. The SFR process is largely automated. The IRS gathers Forms W-2, 1099 and similar reports for the year, computes tax from those numbers, and proposes an assessment. It is a starting point for collection, not a careful reconstruction of your finances.
Why the SFR Usually Overstates the Tax
An SFR is built from income information, so anything that would lower the tax tends to be missing.
Filing status and household
The IRS typically uses single or married filing separately status and does not include dependents. A taxpayer who would qualify for joint or head of household status, or for child-related credits, loses those benefits on the SFR.
Deductions and business expenses
The standard deduction is generally applied, but itemized deductions are not. For self-employed people the gap is often larger: Form 1099 receipts may be taxed as gross income with no offset for business expenses, while self-employment tax is still added.
Investment sales with no cost basis
When a broker reports the proceeds of a sale without the purchase price, the SFR may treat the entire amount as gain. A home sale, stock sale or retirement distribution can look far more taxable than it is.
Penalties layered on top
Because no return was filed, failure-to-file and failure-to-pay penalties, and sometimes an estimated tax penalty, are calculated on the inflated tax, which magnifies the difference.
The Notice Trail and the Deadlines That Matter
The SFR process moves through specific letters, and each one changes what can be done.
The proposed assessment letter
The IRS usually first sends a proposed assessment, commonly a CP2566, showing the proposed tax and inviting the taxpayer to file a return or explain why none was required. Responding at this stage, with a complete original return, is often the simplest way to replace the SFR figures.
The statutory notice of deficiency
If there is no adequate response, the IRS issues a statutory notice of deficiency, often a CP3219N in automated SFR cases. It generally gives 90 days, or 150 days if addressed to someone outside the United States, to petition the U.S. Tax Court. Our article on the Tax Court petition and notice of deficiency explains that step. During that window, the IRS may also consider an original return.
After the tax is assessed
Once the Tax Court window passes, the IRS assesses the tax and begins collection notices. At that point, an original return can still be submitted, and the IRS generally reviews it through its audit reconsideration process. Collection does not automatically stop while that review happens.
Replacing the SFR With an Original Return
Replacing an SFR usually means preparing an accurate, signed original return for the year, not an amended return, because the taxpayer never filed one. The return reports the income the IRS already knows about, along with the deductions, credits, expenses and basis the taxpayer can support.
- IRS wage and income transcripts show what was reported for the year.
- Bank statements, invoices and receipts support business expenses.
- Brokerage records and closing statements establish cost basis.
- Records of dependents support status and credits.

Limitations Periods and Collection Consequences
A substitute for return prepared by the IRS generally does not start the normal limitations period for assessing tax on that year. That period typically begins only when the taxpayer files a return, which leaves an unfiled year open. Once tax is assessed, the IRS generally has ten years to collect it.
SFR years can also complicate a bankruptcy. Older income taxes can sometimes be discharged, but courts have been strict about returns filed after the IRS has already assessed tax, so the timing of a late return can matter. Our article on discharging tax debt in bankruptcy discusses the rules.
How Our Firm Helps With SFR Assessments
The Somal Law Firm in Pleasanton represents individuals and small businesses in IRS disputes, audits and appeals across the Tri-Valley and the East Bay. In an SFR matter, we compare the IRS figures with the taxpayer's records, coordinate the original returns, and address any collection activity while the IRS reviews them.
A first meeting goes further when it includes every IRS letter about the year, any wage and income transcripts already downloaded, and whatever records exist for income, expenses and dependents. Missing paperwork is common in these cases, and part of the work is identifying which records can still be recovered from banks, brokers and former employers.
Frequently asked questions
Can I file my own return after the IRS files an SFR?
Generally yes. The IRS accepts original returns after an SFR, though the procedure and timing depend on what stage the account has reached.
Does an SFR mean I committed a crime?
An SFR is a civil procedure for assessing tax. In the typical case, the focus is on filing accurate returns and then resolving whatever balance remains.
Will filing a return reduce the penalties?
Penalties are usually recalculated on the corrected tax, so a lower tax often means lower penalties. Separate relief may be available in some cases.
Does California do the same thing?
The Franchise Tax Board can also estimate income and issue a proposed assessment when a state return is missing.
