IRS Audit of a $3 Million Lottery Prize Resolved With No Additional Tax or Penalties
Our firm recently represented a taxpayer in an IRS examination that began with a $3 million lottery prize and an amended federal income tax return prepared and filed before we were involved. The examination closed with no additional tax, no penalties, and the taxpayer’s original tax liability left unchanged.
Here is how that happened, and why the strategy matters for anyone walking into an audit with a problem return already on file.
How a Lottery Win Became an IRS Examination
The taxpayer won a $3 million lottery prize and reported it correctly on the original federal income tax return as gambling income.
A prior tax preparer then filed an amended return that attempted to treat the taxpayer as being engaged in the trade or business of professional gambling. That amended return claimed approximately $1.15 million in purported gambling-related business expenses and sought to reduce the taxpayer’s federal income tax liability by approximately $358,000.
The IRS opened an examination.
Why We Did Not Defend the Amended Return
When we became involved, we made a deliberate choice. We were not going to defend positions that could not be substantiated.
Instead, we worked through the IRS examination process to establish the proper tax treatment of the winnings, address the issues the amended filing had created, and keep the examination from generating additional exposure for the taxpayer. In an audit, the fight you pick matters as much as how hard you fight it. Defending an indefensible return invites penalties. Controlling the examination and steering it to the correct result protects the client.
The Result
The IRS examination concluded that the taxpayer was not engaged in the trade or business of professional gambling and disallowed the amended-return claim. What matters is what the examination did not do. It closed with
- $0 in additional tax assessed
- $0 in examination penalties assessed
- The tax liability reported on the taxpayer’s original return left unchanged
The examination also identified an additional income-reporting issue, but the IRS made no additional adjustment to the taxpayer’s liability as part of the examination.
What This Case Teaches
The best strategy in a tax controversy is not always to defend every position taken on a previously filed return. When a taxpayer comes to us after a problematic return or amended return has already been filed, the first step is to independently analyze the underlying facts, determine the correct tax treatment, and build a strategy for limiting additional civil tax and penalty exposure.
That is the core of how we approach IRS audit representation. The goal is not to win an argument. The goal is to end the examination with the smallest possible damage to the client, and in this case that meant zero.
Gambling and lottery income has its own set of reporting rules and traps, which is why we maintain a dedicated practice in the taxation of gambling winnings.
After the Audit
With the examination phase concluded without additional tax or penalties, our firm is now assisting the taxpayer with correcting subsequent tax filings and analyzing available collection alternatives for the remaining back tax liability, including options such as an offer in compromise where the facts support one.
An audit that closes well is not always the end of the story. Getting the follow-through right is part of the representation.
Frequently Asked Questions
Are lottery winnings taxed as gambling income?
Yes. Lottery winnings are taxable income and are generally reported as gambling winnings on a federal income tax return. For a casual player, gambling losses can only be deducted up to the amount of winnings, and only as an itemized deduction.
Can a lottery winner claim professional gambler status?
Only in rare circumstances. Professional gambler treatment requires being genuinely engaged in gambling as a trade or business, which the IRS and the courts evaluate on the full facts and circumstances. A one-time prize almost never supports it, and claiming it without substantiation invites an examination.
What if a preparer already filed a return I am worried about?
Do not wait for the IRS to find it. Have the return independently reviewed, understand the exposure it creates, and get a strategy in place before an examination starts. The earlier that work happens, the more options exist for limiting tax and penalty exposure.
Every tax matter depends on its individual facts and circumstances. Past results do not guarantee a similar outcome in any other matter.
