Unfiled Tax Returns

An unfiled tax return does not go away, and it does not stay quiet. The IRS matches W-2s, 1099s and brokerage reports against what was filed, and when nothing was filed it can assess tax on its own terms. Getting current is usually straightforward. Getting current in the right order is what protects the refund, the penalties and, in some cases, the client.

Whiteford's tax controversy attorneys bring individuals and businesses current on federal and state filings, replace IRS-prepared returns with accurate ones, and resolve the balance that remains. Michael March takes calls from taxpayers directly, and initial consultations are confidential and complimentary.

What the IRS does when you do not file

When a return is not filed, the IRS can prepare one for you. Section 6020(b) authorizes the agency to build a substitute for return from third-party data such as W-2s, 1099s and brokerage reporting. That return is treated as prima facie valid, and it is almost always worse than the return you would have filed: it grants the standard deduction and little else, with no itemized deductions, no basis in securities sold, no business expenses, and no filing status more favorable than single or married filing separately.

A substitute for return is the IRS's opening number, not the end of the process. Filing your own original return after a substitute for return is permitted, and it is usually the single highest-value step in a case. It also starts a clock: under Section 6501(b)(3), a substitute for return does not begin the assessment statute of limitations, so the three-year period runs from the date you file, not from the date the IRS filed for you.

Why the assessment clock never starts

The same principle applies to the assessment period generally. A filed return typically starts a three-year window under Section 6501(a), stretched to six years under Section 6501(e) when more than 25 percent of gross income was omitted. Where no return was filed, Section 6501(c)(3) leaves the period open with no expiration, and a false or fraudulent return does the same under Section 6501(c)(1).

The practical consequence is that an unfiled year stays open indefinitely while a filed year closes in three years. Filing is what starts the clock, which is one reason an accurate return is worth more than waiting to see whether the IRS notices.

How many years you have to file

IRS Policy Statement 5-133 sets an internal enforcement norm of six years of delinquent returns, with managerial approval required to go further. The Tax Court addressed the policy in Gregg v. Commissioner, describing it as the agency's own enforcement procedure rather than a taxpayer entitlement.

The IRS routinely requires filings beyond six years when you apply for an installment agreement, an offer in compromise, or innocent spouse relief, and filing beyond six years can also work in your favor where an older year would generate a refund or a loss carryforward.

The right number for a particular taxpayer comes from the transcripts: which years show a substitute return, which show income the IRS already knows about, and which older years would produce a refund or a loss that carries forward.

Refunds on late returns and the three-year lookback

Section 6511(a) allows a refund claim within three years of the date the return was filed, or two years from the date the tax was paid, whichever is later, so filing a return years late does not by itself forfeit a refund claim.

What limits recovery is the lookback in Section 6511(b)(2)(A): a refund cannot exceed the tax paid during the three years immediately preceding the claim, plus the period of any extension of time to file. Because withholding is treated as paid on the original due date, a return filed more than three years after its due date, counting any extension, usually falls outside that window.

Penalties that accrue on an unfiled return

The failure-to-file penalty under Section 6651(a)(1) runs at 5 percent of the unpaid tax per month, capped at 25 percent, and a return filed more than 60 days late carries a minimum of the lesser of the tax due or $525 for returns due in 2026. Where tax is also unpaid, the failure-to-pay penalty runs alongside it, and interest compounds daily on everything. Our failure-to-file penalty page walks through the calculation.

Penalty relief for a nonfiler generally turns on reasonable cause, an ordinary business care and prudence standard, or first-time abatement where the prior three years were clean. Both are easier to establish when the missing returns are filed voluntarily and accurately, before the IRS has to ask. See penalty abatement for how each track works.

State returns are part of the same problem

Most nonfilers have missing state returns for the same years, and Maryland, Virginia and the District each receive federal data and issue their own assessments. Bringing the federal years current without the state years leaves the account half-fixed, and each state agency has its own penalties, collection tools and deadlines. We coordinate both sets of filings so the sequence works across agencies.

When not filing becomes a criminal matter

Most delinquent filers are never prosecuted, but the exposure is real enough to plan around. Section 7203 makes a willful failure to file a misdemeanor punishable by up to one year, and Section 7201 makes a willful attempt to evade tax a felony where there is an affirmative act beyond not filing, such as falsified records or concealed accounts. The IRS has also stepped up nonfiler enforcement in recent years.

Where the facts include unreported cash income, offshore accounts, or non-filing that follows a prior IRS contact, get counsel involved before submitting anything. A voluntary filing is not a defense once an examination or criminal referral is already underway, and privilege does not extend to a return preparer.

How we bring a nonfiler current

The sequence matters more than most people expect, and doing it out of order costs money.

• Start with the record, not the returns. Account and wage and income transcripts show which years are open, which carry a substitute return, what the IRS already knows about your income, and where each deadline falls.
• Reconstruct what is missing. Third-party data covers most of a typical return; bank and brokerage statements, prior filings and documented, reasonable estimates fill in the rest.
• File accurate original returns for every open year, replacing substitute returns, and request audit reconsideration where a substitute year has already been assessed at an inflated figure.
• Resolve the balance once the real number is established, through an installment agreement, an offer in compromise, currently not collectible status during genuine hardship, or penalty relief. Our back taxes page covers what happens once a balance exists.

Why Whiteford

Whiteford Tax Defense sits inside a full-service firm of more than 200 attorneys with 19 offices across ten states and the District of Columbia. Nonfiler cases rarely stay in one lane: a stack of missing returns becomes a substitute-return assessment, then a lien, then a question about whether the years carry criminal exposure.

Michael March practices civil and criminal tax controversy and handles matters from first notice through United States Tax Court and federal district court. The firm's work includes bringing multi-year nonfilers current, replacing substitute returns, and negotiating the resulting balance.
