(a) In general. Section 4401 imposes a tax on all wagers, as defined in section 4421. See section 4421 and § 44.4421-1 for definition of the term “wager.”

(b) Rate of tax; amount of wager—(1) Rate of tax. The tax is imposed at the rate of 10 percent of the amount of any taxable wager.

(2) Amount of wager. (i) The amount of the wager is the amount risked by the bettor, including any charge or fee incident to the placing of the wager as provided in subdivision (iv) of this subparagraph, rather than the amount which he stands to win. Thus, if a bettor bets $5 against a bookmaker's $7 with respect to the outcome of a prize fight, the amount of the wager subject to tax is $5.

(ii) In the case of a “parlay” wager (i.e., a single wager made by a bettor on the outcome of a series of events, usually horse races), the amount of the taxable wager is the amount initially wagered by the bettor irrespective of whether the parlay is successful. In the case of an “if” wager, the amount of the taxable wager is the total of all amounts wagered on each selection of the bettor. For example, A makes a $10 wager on horse R with the understanding that if horse R wins, $5 is to be wagered on horse S and $5 on horse T. If horse R wins, the taxable wager is $20. If horse R loses, the taxable wager is $10. In determining the amount of a taxable wager involving the features of, or a combination of, “parlay” and “if” bets, such as wagers sometimes referred to as a “whipsaw” or an “if and reverse” bet, the rules set forth above relating to “parlay” and “if” bets are to be followed. For example, assume B wagers $10 on horse R with the understanding that if horse R wins, $5 is to be placed as a parlay wager on horses S and T. In such a case, if horse R loses, the taxable wager is $10; if horse R wins, there are two taxable wagers amounting in the aggregate to $15.

(iii) In the case of punchboards with prizes of merchandise, cash, or free plays listed thereon, the amount of the taxable wager is the amount risked by the bettor for all chances taken by him, including the chances taken by the bettor in lieu of the acceptance of an equivalent amount in cash or merchandise.

(iv) In determining the amount of any wager subject to tax there shall be included any charge or fee incident to the placing of the wager. For example, in the case of a wager with respect to a horse race, any amount paid to a bookmaker for the purpose of guaranteeing the bettor a pay-off based on actual track odds is to be included as a part of the wager. Similarly, in the case of a lottery, any amount paid to the operator thereof by the bettor for the privilege of making a contribution to the pool or bank is also to be included in the amount of the wager. However, the amount of the wager subject to tax shall not include the amount of the tax where it is established by actual records of the taxpayer that such amount of tax was collected from the bettor as a separate charge.

(a) In general. (1) Every person engaged in the business of accepting wagers with respect to a sports event or a contest is liable for the tax on any such wager accepted by him. Every person who operates a wagering pool or lottery conducted for profit is liable for the tax with respect to any wager or contribution placed in such pool or lottery. To be liable for the tax, it is not necessary that the person engaged in the business of accepting wagers or operating a wagering pool or lottery physically receive the wager or contribution. Any wager or contribution received by an agent or employee on behalf of such person shall be considered to have been accepted by and placed with such person.

(2) Any person required to register under section 4412 by reason of having received wagers for or on behalf of another person, but who fails to register the name and place of residence of such other person (hereinafter in this subparagraph referred to as principal), shall be liable for the tax on all wagers received by him during the period in which he has failed to so register the name and place of residence of such principal. Subsequent compliance with section 4412 by the person receiving wagers for another does not relieve him of his liability and duty to pay such tax, nor will the fact that such person incurs liability with respect to the tax on such wagers, relieve his principal of liability for the tax imposed under section 4401 with respect to such wagers. Accordingly, both the person receiving the wagers and his principal shall be liable for the tax on such wagers until the tax is paid. Payment of the tax on such wagers shall not relieve the person receiving wagers of any penalty for failure to register as required by section 4412. This subparagraph has application only to wagers received after September 2, 1958.

(b) In business of accepting wagers. A person is engaged in the business of accepting wagers if he makes it a practice to accept wagers with respect to which he assumes the risk of profit or loss depending upon the outcome of the event or the contest with respect to which the wager is accepted. It is not intended that to be engaged in the business of accepting wagers a person must be either so engaged to the exclusion of all other activities or even primarily so engaged. Thus, for example, an individual may be primarily engaged in business as a salesman, and also for the purpose of the tax be engaged in the business of accepting wagers.

(c) Lay-offs. If a person engaged in the business of accepting wagers or conducting a lottery or betting pool for profits lays off all or part of the wagers placed with him with another person engaged in the business of accepting wagers or conducting a betting pool or lottery for profit, he shall, notwithstanding such lay-off, be liable for the tax on the wagers or contributions initially accepted by him. See § 44.6419-2 for credit and refund provisions applicable with respect to laid-off wagers.

The tax attaches when (a) a person engaged in the business of accepting wagers with respect to a sports event or a contest, or (b) a person who operates a wagering pool or lottery for profit, accepts a wager or contribution from a bettor. In the case of a wager on credit, the tax attaches whether or not the amount of the wager is actually collected from the bettor. However, if an amount equivalent to the amount of the wager is paid to the bettor prior to the close of the calendar month in which such wager was accepted, either because of the cancellation of the event upon which the wager was placed, or because the wager was cancelled or rescinded by mutual agreement, the wager need not be reported on the taxpayer's return for such month. Where such cancellation or rescission takes place in a month subsequent to the month in which the wager was accepted, credit or refund of the tax paid with respect to such wager may be made subject to the provisions of § 44.6419-1.

(a) Parimutuel wagering enterprises. Section 4402 provides that no tax shall be imposed by section 4401 on any wager placed with, or on any wager placed in a wagering pool conducted by, a parimutuel wagering enterprise licensed under State law.

(b) Wagering machines—(1) In general. Section 4402 provides that no tax shall be imposed by section 4401 on any wager placed in a coin-operated device (as defined in section 4462 as in effect for years beginning before July 1, 1980), or on any amount paid, in lieu of inserting a coin, token, or similar object, to operate a device described in section 4462(a)(2) (as so in effect). These devices include:

(i) So-called “slot” machines that operate by means of the insertion of a coin, token, or similar object and that, by application of the element of chance, may deliver, or entitle the person playing or operating the machine to receive cash, premiums, merchandise, or tokens; and

(ii) Machines that are similar to machines described in paragraph (b)(1)(i) of this section and are operated without the insertion of a coin, token, or similar object.

(2) Examples. The following devices and machines are examples of the devices referred to in paragraph (b)(1) of this section:

(i) A machine that is operated by means of the insertion of a coin, token, or similar object and that, even though it does not dispense cash or tokens, has the features and characteristics of a gaming device whether or not evidence exists as to actual payoffs.

(ii) A so-called crane machine, claw, digger, or rotary merchandising type device that is operated by the insertion of a coin and adjustment of a control lever for the purpose or removing from the machine, by gripping, pushing, or other manipulation articles such as figurines, lighters, etc., in the machine.

(iii) A pinball machine equipped with a pushbutton for releasing free plays and a meter for recording the plays so released, or equipped with provisions for multiple coin insertion for increasing the odds.

(iv) Pinball machines in connection with which free plays are redeemed in cash, tokens, or merchandise, or prizes are offered to any person for the attainment of designated scores.

(v) A coin-operated machine that displays a poker hand or delivers a ticket with a poker hand symbolized on it that entitles the player to a prize if the poker hand displayed by the machine or symbolized on the ticket constitutes a winning hand.

Every person liable for tax under section 4401 shall keep such records as will clearly show as to each day's operations:

(a) The gross amount of all wagers accepted;

(b) The gross amount of each class or type of wager accepted on each separate event, contest, or other wagering medium. For example, in the case of wagers accepted on a horse race, the daily record shall show separately the gross amount of each class or type of wagers (straight bets, parlays, “if” bets, etc.) accepted on each horse in the race. Similarly, in the case of the numbers game, the daily record shall show the gross amount of each class or type of wager accepted on each number.

(a) In general. The tax imposed by section 4401 applies to wagers (1) accepted in the United States, or (2) placed by a person who is in the United States (i) with a person who is a citizen or resident of the United States, or (ii) in a wagering pool or lottery conducted by a person who is a citizen or resident of the United States. All wagers made within the United States are taxable irrespective of the citizenship or place of residence of the parties to the wager. Thus, the tax applies to wagers placed within the United States, even though the person for whom or on whose behalf the wagers are received is located in a foreign country and is not a citizen or resident of the United States. Likewise, a wager accepted outside the United States by a citizen or resident of the United States is taxable if the person making such wager is within the United States at the time the wager is made.

(b) Examples. The following examples illustrate the application of paragraph (a) of this section:
