How Gambling Winnings Can Trigger IRS Collections in Missouri

Winning money from gambling can feel like hitting the jackpot in more ways than one. Whether the money comes from a casino, sports betting, poker tournaments, or an online betting platform, the excitement of a big win can make it feel like easy money. However, what many taxpayers don’t realize is that gambling winnings are fully taxable income. When those winnings aren’t reported properly on a tax return, it can trigger IRS notices, unexpected tax bills, and eventually IRS collection actions.

At ALTA Tax Relief, we have experience helping taxpayers who find themselves facing IRS tax debt related to gambling winnings. If, after reading this blog, you still have questions or need help resolving your tax issue, call us at 314-202-4342 or visit our website.

Gambling Winnings Are Always Taxable

Under federal tax law, gambling winnings must be reported as income on your tax return. This includes winnings from:

• Casinos

• Sports betting

• Poker tournaments

• Slot machines

• Horse racing

• Online gambling platforms

• Lotteries and raffles

Casinos and gambling institutions often issue Form W-2G, which reports winnings directly to both the taxpayer and the IRS. Even if you do not receive a W-2G, the income is still taxable and must be reported. The IRS uses computer matching programs to compare third-party reports with what taxpayers report on their returns. When gambling income reported to the IRS does not appear on a tax return, the discrepancy is flagged, and the IRS may contact the taxpayer.

New Rules for 2026: The 90% Loss Deduction Cap

Starting January 1, 2026, a significant change in tax law—enacted by the "One Big Beautiful Bill"—impacts how recreational gamblers deduct their losses. Under previous rules, taxpayers could deduct 100% of their gambling losses up to the amount of their winnings. As of 2026, the IRS will limit the deduction of gambling losses to 90% of winnings.

This means even if you break even for the year, you may still owe taxes on "phantom income". For example, if you won $100,000 but lost $100,000, you can now only deduct $90,000 in losses, leaving $10,000 in taxable income. This change makes it more important than ever to consult with ALTA Tax Relief to ensure your filings are accurate and your tax liability is minimized.

The CP2000 Notice: A Common Starting Point

One of the most common notices issued in these situations is a CP2000 Notice, which informs the taxpayer that income reported to the IRS by a third party does not match what was reported on their tax return. The CP2000 typically proposes additional tax based on the unreported income.

If the notice is ignored or not handled properly, the IRS may assess the additional tax along with:

• Accuracy-related penalties

• Failure-to-pay penalties

• Interest that continues to accumulate daily

What started as a gambling win can quickly turn into a growing tax balance owed to the IRS.

When IRS Collections Begin

Once the tax is assessed and the balance remains unpaid, the IRS collection process begins. The IRS sends a series of increasingly serious notices designed to encourage payment. Typically, the notices progress in stages:

• CP14: The first notice showing the balance due.

• CP501 or CP503: Reminder notices.

• CP504: Notice of intent to levy certain assets.

• Letter 1058 or LT11: Final Notice of Intent to Levy.

By the time a taxpayer receives the final notice, the IRS has the legal authority to begin taking aggressive collection actions. These actions can include wage garnishments, bank account levies, and the filing of a federal tax lien.

Gambling Losses Can Help Reduce the Tax

One important rule many taxpayers overlook is that gambling losses can offset gambling winnings, but only if they are properly documented and reported. To claim these losses, you must itemize your deductions on Schedule A. If you take the standard deduction, you cannot deduct your losses, even though you must still report 100% of your winnings.

The IRS generally expects taxpayers to keep detailed records, such as:

• Betting slips or tickets

• Casino player card statements

• Online betting records

• Bank or credit card records related to gambling activity

• A daily or session-based win/loss log

In many CP2000 situations, the IRS initially assumes the entire amount of winnings is taxable because losses were not reported on the return. With proper documentation, a tax professional at ALTA Tax Relief may be able to reconstruct the gambling activity and reduce the tax owed.

Professional vs. Recreational Gambler Status

For those who gamble "regularly and continuously" with the primary purpose of earning a profit, the IRS may classify you as a professional gambler. Professionals report their activity on Schedule C as a business. This status offers significant advantages:

• Deductions for "ordinary and necessary" business expenses like travel, lodging, and subscriptions.

• Avoids the need to itemize on Schedule A.

• Allows the netting of wins and losses to arrive at a net profit, which avoids inflating your Adjusted Gross Income (AGI).

However, qualifying is difficult and requires meticulous record-keeping. ALTA Tax Relief can evaluate your activity to see if you qualify for professional status to lower your tax burden.

The Problem Often Gets Worse Over Time

Taxpayers often ignore IRS notices because they are unsure how to respond or believe the problem will resolve itself. Unfortunately, IRS tax debt rarely goes away on its own. As time passes, penalties and interest continue to accumulate, making the balance larger and harder to resolve. Even if the IRS has already begun collection actions, solutions are often still available.

IRS Resolution Options May Be Available

Depending on the taxpayer’s financial circumstances, several IRS resolution options may help resolve gambling-related tax debt:

• Installment Agreements: Monthly payment plans that fit your budget.

• Penalty Abatement: Requesting the removal of penalties due to "reasonable cause".

• Offer in Compromise (OIC): Settling your tax debt for less than the full amount owed if you can demonstrate an inability to pay.

• Currently Not Collectible (CNC) Status: Temporarily pausing collection actions if paying would create an economic hardship.

Each case is unique, and the best solution depends on the taxpayer’s financial situation and the details of the tax liability.
