One Step Ahead
The most common mistake in a multi-year filing gap is starting with the earliest year and working forward. It feels orderly. It is usually the wrong sequence, and it occasionally means preparing returns that were never required.
Before any return is prepared, three things need to be established: which years the IRS considers open, what income was already reported to the IRS by third parties, and whether the agency has already filed returns on your behalf.
Resolving unfiled tax returns begins with IRS transcripts, not with tax preparation. Transcripts show which years carry a filing requirement, what third-party income the IRS has on record, and whether a Substitute for Return has already been filed. IRS Policy Statement 5-133 generally treats six years of filed returns as sufficient for compliance, though the required number depends on the facts.
three steps to success
What This Engagement Covers
A filing gap is easier to scope accurately than most people expect, and the scope is usually narrower than feared.
- Full transcript retrieval — account, return, record of account, and wage and income transcripts for every year at issue
- Filing requirement analysis — determining which years actually require a return, and which do not
- Scope determination — how many years must be filed, with the reasoning documented rather than assumed
- Income reconstruction — rebuilding records where documentation is incomplete, using wage and income transcripts, bank and brokerage records, and business books
- Substitute for Return replacement — preparing the correct return where the IRS has already assessed under IRC §6020(b)
- Refund preservation — identifying years where a refund is still claimable under the three-year window in IRC §6511, and prioritizing those filings
Wage and income transcripts show every information return filed under your Social Security number — Forms W-2, 1099-NEC, 1099-B, 1099-DIV, 1099-INT, 1099-DA for digital assets, K-1s, 1098s, and more.
For a technology executive with equity compensation, that record can be substantial: brokerage 1099-Bs reporting gross proceeds from RSU sell-to-cover transactions and option exercises, with no cost basis adjustment. Left unfiled, the IRS may compute tax on the full proceeds as though basis were zero. The assessed balance can be several multiples of the correct liability.
The same pattern appears with rental activity, partnership K-1s, and cryptocurrency proceeds. In each case, filing an accurate return is the mechanism that corrects it.
Who Benefits Most From This Work
- Taxpayers with two or more unfiled years, particularly where income varied significantly across them
- High earners whose gap includes years with equity compensation, property sales, or large brokerage activity
- Business owners whose personal and entity filings both lapsed and must be reconstructed in the correct order
- Anyone who has received IRS Letter 5972C, CP59, CP63, or a Substitute for Return notice
- Taxpayers whose prior preparer became unresponsive mid-engagement
Our Approach
- Transcripts first. We obtain the full transcript set before discussing preparation scope. Nothing is estimated at this stage.
- Scope memo. A written determination of which years will be filed and why, including any year deliberately excluded and the basis for excluding it.
- Reconstruction and preparation. Returns prepared in the sequence that protects refund years and addresses Substitute for Return assessments first.
- Filing and balance position. Returns filed, resulting balances identified, and the file handed to penalty and payment work where a balance remains.

IRS Policy Statement 5-133 generally treats six years as sufficient for compliance, subject to the facts and to IRS management discretion. More years may be required where there is significant income, business activity, or an open examination. Fewer may be required where filing requirements did not exist in some years.
No. Under IRC §6501(c)(3), where no return was filed, the assessment period never begins to run. The year remains open indefinitely. The ten-year collection period in IRC §6502 only starts once tax is assessed.
Yes. A Substitute for Return under IRC §6020(b) is an IRS estimate, not a final determination. Filing an accurate original return afterward is permitted and is the standard corrective step.
Possibly. IRC §6511 generally requires a refund claim within three years of the return’s due date. Refunds from years outside that window are forfeited. This is why refund years are prioritized in the filing sequence.
