On a transcript, the substitute for return announces itself: a TC 150 posting with no return you ever signed behind it, built from every W-2, 1099, and broker statement third parties reported. The construction rules guarantee the maximum tax: single or married filing separately, no dependents, standard deduction only, and zero basis on everything you sold - the IRS taxes the entire proceeds of that stock sale as gain.

Then the assessment is real, collection follows, and the trap closes around people who assume a fake return creates a fake debt. It does not. It creates a real debt from fake math.

The Repair Is a Real Return

File the actual return for the SFR year and the IRS processes it through reconsideration, adjusting the assessment to reality - true filing status, dependents, deductions, business expenses, actual basis. The reductions are routinely dramatic. A client whose SFR taxed $180,000 of stock proceeds owed almost nothing once the basis showed the actual gain was a few thousand dollars. The IRS's own wage and income transcripts provide the data to rebuild the year.

Three Clocks, Three Different Answers

Here is the insider layer. The SFR assessment starts the collection statute - the IRS put itself on its own 10-year clock, which eventually works for you. But the SFR does not start the refund statute: refunds die three years from the original due date whether or not the IRS filed anything, so withholding from a decade ago is gone. And for bankruptcy, the news is worse: in several federal circuits, a return filed after the IRS assessed via SFR may never count as a return for discharge purposes, locking that debt out of bankruptcy forever. The same year can be collectible by the IRS, unrefundable to you, and undischargeable in court - all because of filing timing.

The Moral Is Speed

Every month between the SFR and your real return forecloses something. If your transcripts show SFR years - or you suspect they might - get the actual returns built and filed now, then resolve whatever balance survives contact with the truth. Both steps are standard work in my office. Let's talk.
