Substitute for Return (SFR) — When the IRS Files a Return for You

Direct answer

A substitute for return (SFR) is a return the IRS prepares when you did not file — using W-2s, 1099s, and other payor documents it received. The IRS then assesses tax, often with no deductions or credits you would claim on a real return.

SFR is not always a mailed CP notice — it shows up on your account transcript as an IRS-prepared assessment. The balance can look shocking because the IRS usually omits expenses, dependents, and credits you would include if you filed.

What a substitute for return means

When you do not file after delinquent notices (CP59, CP515), the IRS may prepare a return under its authority using third-party income documents. It assesses tax, penalties, and interest — then collection can follow like any other balance.

How SFR appears on your account transcript

  • TC 150 (assessment) with language indicating substitute or IRS-prepared return.
  • TC 971 with Action Code 141 often indicates ASFR/SFR posted.
  • Assessment date long after the original due date with no matching return transcript you filed.
  • Balance higher than expected with wage & income showing income but no taxpayer return on file.

Verify with wage & income and account transcripts

  • Wage & income transcript lists what payors reported — compare to the SFR assessment.
  • Account transcript shows the assessed balance and collection path after SFR.
  • See our CP59 and CP515 guides if you received delinquent filing notices before SFR.

What to do if the IRS filed an SFR

  • File an accurate original return for the year — not only Form 1040-X in many SFR situations; professional help may be appropriate.
  • Gather W-2s, 1099s, and deduction records the IRS did not use.
  • After your return processes, pull a fresh transcript — TC 150 from your filed return should replace the SFR story.
  • Do not ignore the balance — SFR assessments can lead to CP14, levy notices, and liens.

SFR vs a return you filed

If you filed but the IRS shows SFR, your return may still be processing or may have been rejected. Compare notice dates to posting dates and respond with proof of filing if TC 150 from your return is missing.

Common questions

Is SFR the same as CP59?

No. CP59 is a delinquent filing notice asking you to file. SFR is what the IRS may do if you do not file — it prepares and assesses a return using income documents it has.

Why is my SFR balance so high?

IRS-prepared returns typically use single filing status, omit deductions and credits, and may not reflect withholding accurately. Filing your own return often lowers the tax — but it must be processed.

What is TC 971 AC 141?

On many transcripts, Action Code 141 with TC 971 indicates a substitute return (ASFR) posted. See our IRS transcript codes guide for TC 971 action codes.
