By Rick Yandle, Esq., CPA — federal criminal & civil tax defense
It usually arrives as a letter from the IRS, and it makes no sense at first. Deductions you never took. A credit you never asked for. A business loss for a business you do not have. Slowly it dawns on you: the tax preparer you paid to handle this put things on your return that were not true. Now the IRS is asking you about it — and the fear underneath every question is the same. Am I the one in trouble for what someone else did?
Here is the honest answer, in the order that matters: yes, you are generally still responsible for the correct tax and the interest, because a signed return is treated as yours — but the penalties are a separate question, and a taxpayer who genuinely relied in good faith on a professional can often avoid them.
The hard part: it is still your return
Start with the part no one likes to hear. When you sign a tax return, the law generally treats it as yours — including the numbers a preparer put on it. If those numbers were wrong and you actually owed more, you are generally responsible for the correct tax and the interest that built up on it. "My preparer did it" does not erase the underlying tax, because that tax was always yours to pay in the first place.
That is the floor. But it is not the whole story, and the rest of the story is where having someone in your corner matters.
The better part: penalties are a different question
The tax itself is one thing; the penalties on top of it are another — and that is where innocent taxpayers often get real relief. The IRS can pile accuracy and fraud penalties onto an underpayment, but a taxpayer who genuinely did not know and reasonably relied in good faith on a competent professional may be able to avoid those penalties. The key word is reasonably: handing everything to a credentialed preparer and honestly not knowing they invented deductions is very different from signing a return claiming a business you have never heard of without a second glance. Whether your reliance was reasonable is fact-specific, and it is exactly the kind of showing worth making carefully rather than in an off-the-cuff phone call with the examiner.
The unsettled part: how long the IRS has
There is one genuinely open question that can matter enormously, and you should know it is disputed. Normally the IRS has a limited number of years to come after a return. But that clock disappears if the return was fraudulent. So the question becomes: if the fraud was the preparer's and not yours, does the IRS still get unlimited time against you?
The courts do not fully agree, and the differences matter. The Tax Court has said a return preparer's fraud can hold the year open indefinitely even when the taxpayer was innocent (Allen v. Commissioner, 2007), and the Second Circuit has applied the same idea where the person who prepared and filed the returns acted fraudulently (City Wide Transit, 2013). The Federal Circuit went the other way — but in a case involving fraud by an outside tax-shelter lawyer rather than the return preparer, it held that the unlimited period requires the taxpayer's own intent to evade (BASR Partnership, 2015), while noting it was not deciding every preparer or agent scenario. So the controlling rule can turn on the forum and the exact facts. For you, the practical takeaway is simple: do not assume an old year is safely closed just because the fraud was not yours — and do not assume it is hopelessly open either. This is unsettled ground, and it is worth real analysis.
What to actually do
If you think your preparer falsified your return, a few steps protect you. Preserve everything — engagement letters, what you handed over, what came back, how you paid. Do not sign anything else or have an unguarded conversation with the IRS before you understand your exposure. Get the corrected numbers figured out so you know what you truly owe versus what the fraud inflated. And know that the IRS has formal procedures for reporting preparer misconduct — putting the misconduct on the record — though filing a complaint by itself does not change what you owe.
You may have been the victim here. But to the IRS you are, at least at first, just the name on the return — so the goal is to move quickly from "name on the return" to "taxpayer who reasonably relied on a professional and is fixing it the right way."
