Years of unfiled returns. Still fixable.

The two penalties are not the same size

Failure to file runs at 5% of the unpaid tax for each month or part of a month the return is late, capped at 25%. Failure to pay runs at 0.5% on the same base, with the same cap. That is a factor of ten, and it is the arithmetic behind advice that sounds strange the first time you hear it: file even when you cannot pay.

Where both penalties run in the same month, the failure-to-file penalty is reduced by the failure-to-pay amount for that month, so the combined rate is 5% rather than 5.5%. It does not change the conclusion.

There is also a floor. A return more than 60 days late carries a minimum penalty of the lesser of a set dollar amount, adjusted annually for inflation, or 100% of the tax required to be shown on the return. A small balance does not produce a small penalty.

The clock that never starts

The IRS generally has three years from the date a return is filed to assess additional tax. On a year where no return was ever filed, that period never begins. The year stays open indefinitely.

This is the single most important fact on this page, and it cuts one way only. Waiting does not run out any clock in your favour. It runs out a different one: a refund is generally recoverable only within three years of filing the return or two years of paying the tax, whichever is later. Refunds on years filed later than that are simply lost, and we have seen people forfeit real money by not filing years in which they were owed it.

Substitute for Return

When enough time passes, the IRS may prepare a return for you under its own authority, using the income reported about you by employers, banks, and brokers. This is a Substitute for Return, and it is built to be adverse:

• No itemised deductions and no business expenses — gross receipts on a 1099 become profit.
• Filing status set to single or married filing separately, whichever produces more tax.
• No dependents, no credits.
• No basis on securities sales, so the entire proceeds are treated as gain.

The assessed number is therefore usually far higher than the real liability, sometimes by a multiple. A filed original return replacing an SFR routinely reduces the balance substantially — not through negotiation, but because the actual return has the deductions in it. That is the most common good news in this work.

Someone eight years behind asks the same question every time: do I have to file all of them? The short answer is that the IRS generally asks for six. The useful answer is that six is a policy, not a right, and the number of years worth filing is often different from the number required.

Where the six comes from

Internal Revenue Manual policy provides that delinquent return enforcement generally covers the six most recent years, with discretion to require more or accept fewer depending on the facts. It is an administrative practice. It is not a statutory limit, and it does not close the earlier years — those remain open indefinitely because no return was ever filed on them.

File more than six when

• A refund is still recoverable. The three-year window under the refund statute is measured per year. If a year inside it shows an overpayment, filing it puts money back; leaving it unfiled forfeits that money permanently.
• A year carries something forward. A net operating loss, a capital loss carryover, basis in a partnership or S corporation, suspended passive losses. The carryforward has to originate on a filed return to be usable later.
• Self-employment earnings matter. Social Security credits for a self-employed year are recorded from the filed return. Unfiled years are missing years on the earnings record, and there is a limit on how far back that can be corrected.
• Somebody else needs the year. Mortgage underwriting, an immigration application, a professional licence, a divorce settlement, a business sale in diligence. The requirement is whatever that party asks for, not what the IRS would settle for.
• An SFR was assessed on an older year. If the IRS already assessed a bad number, that year has a live balance being collected. Filing the real return is how the number comes down, whether or not it falls inside the six.

Six is usually enough when

• The older years show no refund and no carryforward worth having.
• No substitute return was ever assessed on them, so there is no balance being collected.
• Income in those years was modest and the reconstruction cost would exceed anything it produces.

What changes the answer

Three things move it, and all three need checking before the scope is set:

• A substantial understatement. Once a return is filed, the assessment period is extended to six years where more than 25% of gross income was omitted. That is a reason to get the numbers right on filing, not a reason to delay.
• Fraud. Where a return is false or fraudulent with intent to evade, there is no limitation period at all. Cases with that shape need a lawyer involved before anything is filed, and we will say so rather than proceed.
• Foreign accounts. Unreported offshore accounts change both the procedure and the exposure, and the streamlined filing compliance procedures have their own year counts and certification requirements. They are not compatible with quietly filing six years and hoping.

What the process actually looks like

Authorisation and transcripts first, so the scope is set against what the IRS actually holds rather than against memory. Then the returns, oldest first where carryforwards are involved. Then the balance, once it is a real number. Then penalty relief, which is requested after compliance is restored because that is when eligibility exists.

It usually takes months rather than weeks, and the first month is the one that changes the situation: filed returns replace assessed estimates, and the file stops being a delinquency and becomes a balance with options attached to it.

We will tell you what the years are likely to show before you commit to preparing them, and we will not offer you a figure for what the balance will settle at. That number does not exist until the returns are filed.
