What Happens If the IRS Files a Substitute for Return in Illinois or Nevada?
January 2, 2026

A Substitute for Return, often called an SFR, is one of the most misunderstood IRS actions. For taxpayers in Illinois and Nevada, receiving notices based on an SFR often feels sudden and unfair, especially when deductions and credits were never claimed.

This guide explains what a Substitute for Return is, why the IRS files one, how it affects tax balances, and what Peoria and Las Vegas taxpayers can do to replace an SFR with an accurate return and reduce liability.

What a Substitute for Return Actually Is

A Substitute for Return is a tax return prepared by the IRS when a taxpayer fails to file. The IRS uses income information reported by third parties such as employers and banks to calculate tax.

SFRs do not include itemized deductions, business expenses, dependents, or credits unless specifically reported to the IRS. As a result, SFR balances are usually inflated.

Why the IRS Files SFRs

The IRS files SFRs to create an assessable tax balance when compliance is missing. Once a balance is assessed, the IRS can pursue collection actions.

For taxpayers in Peoria and Las Vegas, this often marks the transition from noncompliance to active enforcement.

How an SFR Affects Your Tax Debt

Once assessed, an SFR-based balance becomes legally enforceable. Penalties and interest begin accruing immediately. The IRS may file liens or issue levies based on the SFR amount.

If left uncorrected, the SFR can lock in a much higher debt than necessary.

Replacing an SFR With a Correct Return

Taxpayers have the right to file an original return to replace an SFR. When a correct return is accepted, the IRS adjusts the balance to reflect accurate income, deductions, and credits.

However, timing matters. Filing after enforcement begins can complicate negotiations.

Common Mistakes After an SFR Is Filed

Many taxpayers ignore SFR notices, assuming the IRS will correct itself. Others rush to file without documentation, triggering audits or disputes.

A controlled filing strategy often produces better outcomes.
