The provision is in the final bill:
?SEC. 70114. EXTENSION AND MODIFICATION OF LIMITATION ON WAGERINGLOSSES.
(a) In General.--Section 165 is amended by striking subsection (d)
and inserting the following:
``(d) Wagering Losses.--
``(1) In general.--For purposes of losses from wagering
transactions, the amount allowed as a deduction for any taxable
year--
``(A) shall be equal to 90 percent of the amount of
such losses during such taxable year, and
``(B) shall be allowed only to the extent of the
gains from such transactions during such taxable year.
``(2) Special rule.--For purposes of paragraph (1), the
term `losses from wagering transactions' includes any deduction
otherwise allowable under this chapter incurred in carrying on
any wagering transaction.''.
(b) Effective Date.--The amendment made by this section shall apply
to taxable years beginning after December 31, 2025.
I opened my H&R Block tax program and recalculated my tax due for 2024 by simply reducing the total losses for the year by 10%. The new figure for total taxes due increased by $214,121 (Form 1040-SR line 24). That is actually the good news. This assumes that the IRS allows session accounting where the sessions are an entire day at each online property. This is how I have been reporting my income. If each session is the length of a single login, then the session wins and losses would be much higher. If the wins or losses from each individual wager were totaled, the tax bill for 2024 would increase by almost $1M.
So the IRS definitions of a win, a loss, and a session are really critical. Also, I file Schedule C as a business. I report my gambling losses as 'returns and allowances' on Schedule C. The tax program does not know these are gambling losses. The tax program will not automatically reduce the losses by 10%.
I am desperate for accurate expert legal interpretations of the new bill. The articles that I have seen so far have not been written by tax experts, and I don't even think anyone in the Senate has a clue as to the implications of this bill for professional gamblers.
