Substitute for Return (SFR): Why the IRS's Number Is Almost Always Too High
When you don't file, the IRS files an SFR on your behalf using 1099s/W-2s — with ZERO deductions or exemptions. Learn how preparing an original return reduces or eliminates that balance.

An IRS Substitute for Return (SFR) is prepared using single filing status with zero itemized deductions, zero business expenses, and zero dependent credits. Filing an original, accurate tax return replaces the SFR assessment and significantly reduces your balance.
When you neglect to file a required federal income tax return, the IRS will eventually prepare one for you under Internal Revenue Code § 6020(b). This official document is called a Substitute for Return (SFR). While taxpayers are relieved that a return was filed, the resulting tax bill is almost always artificially astronomical.
# Why Substitute for Return Assessments Are Extremely Inflated
The IRS calculates an SFR using reported 1099, W-2, and 1098 information sent by third parties.
If you are self-employed (1099-NEC), the IRS taxes 100% of your gross receipts without deducting mileage, office rent, supplies, or contractor expenses.
In addition, statutory Failure-to-File and Failure-to-Pay penalties are calculated on this inflated figure, doubling or tripling what you actually owe.
Critical CPA Takeaway
The IRS explicitly advises in IRM guidelines that taxpayers retain the right to file an original return to replace an SFR assessment at any time.
