If your winnings are reported on a Form W-2G, federal taxes are withheld at a flat rate of 24%. If you didn’t give the payer your tax ID number, the withholding rate is also 24%. Withholding is required when the winnings, minus the bet, are: More than $5,000 from sweepstakes, wagering pools, lotteries, At least 300 times the amount of the bet. Apart from slot machines, the same applies to winnings from lottery, bingo, keno, poker or other games of chance. So, if the amount won on a slot machine is higher than $1200, the casino is required to report it. In other words, all your gambling winnings have to be reported on your tax return as 'other income' on Schedule 1 (Form 1040), line 8.

HARRISBURG, Pa. (CN) — The Pennsylvania Supreme Court ruled that a municipal tax on slot machines outside Philadelphia violates the state constitution because it imposes different rates on casinos depending on their size.
The Mount Airy Casino Resort, in the Poconos, sued the Pennsylvania Department of Revenue, claiming it “imposes grossly unequal local share assessments” based on gross revenue from slot machines, or terminals.
The court agreed, but stayed its Sept. 28 ruling for 120 days to give the Pennsylvania General Assembly time to fix the law that legalized casino gaming.
“We think it most appropriate to leave to the legislative branch the responsibility of fashioning a constitutional local share assessment,” Justice David Wecht wrote for the majority.
The state’s gaming act allows for two different assessments: a $10 million lump sum or a tax of 2 percent of gross terminal revenues, subject to an exemption for the first $500 million of each casino’s gross terminal revenue.
“The non-uniformity inherent in such a scheme is unmistakable,” Wecht wrote.
Mount Airy asked the court to strike the $10 million minimum local share assessment, leaving a uniform 4 percent tax rate for all casinos. The Department of Revenue proposed the opposite. It suggested that the court leave the $10 million minimum local share assessment intact, but eliminate any additional taxes for casinos with gross terminal revenues above $500 million.
“This court is not in the business of drafting complex tax statutes, nor are we experts on the financial condition of Pennsylvania’s casinos or the financial needs of Pennsylvania’s municipalities,” Wecht wrote.
“Under the circumstances presented, we think it most appropriate to leave to the legislative branch the responsibility of fashioning a constitutional local share assessment.”
The General Assembly will have until the last week in January to decide how to tax casinos.

Totaling a taxpayer's Forms W-2G, Certain Gambling Winnings, for the year would seem to be the straightforward way to determine the amount of gambling winnings to report on a tax return. Forms W-2G, however, do not necessarily capture all of a taxpayer's gambling winnings and losses for the year. How are these amounts reported and substantiated on a tax return? Does the answer change if the taxpayer seeks to make a living as a poker player? Do states tax gambling differently?

There are many nuances and recent developments under federal and state tax laws about gambling and other similar activities. With proper recordkeeping and guidance, a taxpayer with gambling winnings may significantly reduce audit exposure.

Income and Permitted Deductions

Under Sec. 61(a), all income from whatever source derived is includible in a U.S. resident's gross income. Whether the gambling winnings are $5 or $500,000, all amounts are taxable.

A taxpayer may deduct losses from wagering transactions to the extent of gains from those transactions under Sec. 165(d). For amateur gamblers, gambling losses are reported as an itemized deduction on Schedule A, Itemized Deductions. The law is not as kind to nonresidents: While nonresidents must also include U.S.-source gambling winnings as income, they cannot deduct gambling losses against those winnings. Nonresidents whose gambling winnings are connected to a trade or business may deduct gambling losses to the extent of winnings, however, under Sec. 873.

Case law and IRS guidance have established that a taxpayer may determine gambling winnings and losses on a session basis.

Neither the Code nor the regulations define the term 'transactions' as stated in Sec. 165(d). Tax Court cases have recognized that gross income from slot machine transactions is determined on a session basis (see Shollenberger, T.C. Memo. 2009-306; LaPlante, T.C. Memo. 2009-226).

What Is a Session?

In 2008, the IRS Chief Counsel opined that a slot machine player recognizes a wagering gain or loss at the time she redeems her tokens because fluctuating wins and losses left in play are not accessions to wealth until the taxpayer can definitely calculate the amount realized (Advice Memorandum 2008-011). This method is also recognized in both Schollenberger and LaPlante, as a by-bet method would be unduly burdensome and unreasonable for taxpayers. To this end, the IRS issued Notice 2015-21, which provides taxpayers a proposed safe harbor to determine gains or losses from electronically tracked slot machine play.

Under Notice 2015-21, a taxpayer determines wagering gain or loss from electronically tracked slot machine play at the end of a single session of play, rather than on a by-bet basis. Electronically tracked slot machine play uses an electronic player system controlled by the gaming establishment—such as the use of a player's card—that records the amount a specific individual won and wagered on slot machine play. A single session of play begins when a taxpayer places a wager on a particular type of game and ends when the taxpayer completes his or her last wager on the same type of game before the end of the same calendar day.

Statistics also show that has made things worse, as some players are quitting the slots altogether.Casinos and slot manufacturers are responding by creating new types of games, many with elements that allow players to use skill to increase their return on games.

A taxpayer recognizes a wagering gain if, at the end of a single session of play, the total dollar amount of payouts from electronically tracked slot machine play during that session exceeds the total dollar amount of wagers placed by the taxpayer on the electronically tracked slot machine play during that session. A taxpayer recognizes a wagering loss if, at the end of a single session of play, the total dollar amount of wagers placed by the taxpayer on electronically tracked slot machine play exceeds the total dollar amount of payouts from electronically tracked slot machine play during the session.

There is little to no guidance defining a session for other casino games, such as poker. Furthermore, because there are different poker game formats (cash and tournament) and game types (Texas hold 'em, pot limit Omaha, etc.), it is unclear whether the one-session-per-day analysis would apply to poker in general. A taxpayer who plays different types of poker games may have to record separate sessions for each type of poker game played each day.

In a 2015 Chief Counsel memorandum (CCM), the IRS concluded that a taxpayer's multiple buy-ins for the same poker tournament could not be aggregated for purposes of determining the reportable amount on a taxpayer's Form W-2G (CCM 20153601F). This analysis implies that the IRS may view each poker tournament buy-in as a separate gambling session. A key point leading to the conclusion was that the buy-ins were not identical because the tournament circumstances were different each time the taxpayer made an additional buy-in.

Requirement to Maintain Accurate Records

In Rev. Proc. 77-29, the IRS states that a taxpayer must keep an accurate diary or other similar record of all losses and winnings. According to Rev. Proc. 77-29, the diary should contain:

• The date and type of the specific wager or wagering activity;
• The name and address or location of the gambling establishment;
• The names of other persons present at the gambling establishment; and
• The amounts won or lost.

It is hard to believe the IRS would disallow a taxpayer's gambling loss deduction solely because the taxpayer did not write down in her diary the names of other persons at her blackjack table. The IRS does acknowledge that a taxpayer may prove winnings and losses with other documentation, such as statements of actual winnings from the gambling establishment.

Special Rules for Professional Gamblers

The professional gambler reports gambling winnings and losses for federal purposes on Schedule C, Profit or Loss From Business. A professional gambler is viewed as engaged in the trade or business of gambling. To compute business income, the taxpayer may net all wagering activity but cannot report an overall wagering loss. In addition, the taxpayer may deduct 'ordinary and necessary' business expenses (expenses other than wagers) incurred in connection with the business.

Whether a gambler is an amateur or a professional for tax purposes is based on the 'facts and circumstances.' In Groetzinger, 480 U.S. 23 (1987), the Supreme Court established the professional gambler standard: 'If one's gambling activity is pursued full time, in good faith, and with regularity, to the production of income for a livelihood, and is not a mere hobby, it is a trade or business.' The burden of proof is on the professional gambler to prove this status.

Despite receiving other forms of income in 1978, Robert Groetzinger was held to be a professional gambler for the year because he spent 60 to 80 hours per week gambling at dog races. Gambling was his full-time job and livelihood. Notably, Groetzinger had a net gambling loss in 1978. Thus, actual profit is not a requirement for professional gambler status.

In addition to applying the standard established in Groetzinger, courts sometimes apply the following nonexhaustive nine-factor test in Regs. Sec. 1.183-2(b)(1) used to determine intent to make a profit under the hobby loss rules to decide whether a taxpayer is a professional gambler:

• Manner in which the taxpayer carries on the activity;
• The expertise of the taxpayer or his advisers;
• The time and effort the taxpayer expended in carrying on the activity;
• Expectation that assets used in the activity may appreciate in value;
• The taxpayer's success in carrying on other similar or dissimilar activities;
• The taxpayer's history of income or losses with respect to the activity;
• The amount of occasional profits, if any, that are earned;
• The financial status of the taxpayer; and
• Elements of personal pleasure or recreation.

What if a professional gambler's ordinary and necessary business expenses exceed the net gambling winnings for the year? In Mayo, 136 T.C. 81 (2011), the court held the limitation on deducting gambling losses does not apply to ordinary and necessary business expenses incurred in connection with the trade or business of gambling. Therefore, a professional gambler may report a business loss, which may be applied against other income from the year.

Limitations on Loss Deductions

Some states do not permit amateur taxpayers to deduct gambling losses as an itemized deduction at all. These states include Connecticut, Illinois, Indiana, Kansas, Massachusetts, Michigan, North Carolina, Ohio, Rhode Island, West Virginia, and Wisconsin. A taxpayer who has $50,000 of gambling winnings and $50,000 of gambling losses in Wisconsin for a tax year, for example, must pay Wisconsin income tax on the $50,000 of gambling winnings despite breaking even from gambling for the year.

Because professional gamblers may deduct gambling losses for state income tax purposes, some state tax agencies aggressively challenge a taxpayer's professional gambler status. A taxpayer whose professional gambler status is disallowed could face a particularly egregious state income tax deficiency if the taxpayer reported on Schedule C the total of Forms W-2G instead of using the session method under Notice 2015-21. In this situation, the state may be willing to consider adjusting the assessment based on the session method if the taxpayer provides sufficient documentation.

Changes Ahead Likely

Tax laws addressing gambling and other similar activities will continue to evolve as new types of games and technologies emerge. Some related tax issues that will come to the forefront include session treatment for online gambling activity and whether daily fantasy sports are considered gambling. As more and more states legalize online gambling and daily fantasy sports, Congress or the IRS will have no choice but to address these issues.
