IRC §225 reaches only the overtime the Fair Labor Standards Act requires, meaning hours past 40 in a workweek, and only the premium half of it. California's daily overtime after the eighth hour produces $0 of federal deduction on a week that never reaches 40 hours.
For tax years beginning after December 31, 2025, IRC §165(d) allows a deduction for only 90% of wagering losses, still capped at wagering gains. A bettor who wins $120,000 and loses $118,000 clears $2,000 and gets taxed on $13,800.
IRC §83(i) lets a qualified employee defer federal income tax on vested private company stock for up to 5 years. The 80% employee rule and a mandatory escrow keep most plans out, and the deferral locks in the vest-date value even if the shares fall to a quarter of it.
A decade of Form 8582 carryforwards comes loose in a single year when you sell, but only if the sale clears three tests. Here is what §469(g) requires, the four transactions that quietly fail it, and what the freed losses are worth on a 2026 return.
Contributing appreciated company shares to a donor-advised fund deducts the full market value and erases the capital gains tax you would have paid to sell them. The deduction lands in the year you fund the account, and the grants can go out for the next decade.
The One Big Beautiful Bill Act repealed the limits on repaying excess advance ACA subsidies for tax years beginning after 2025. A self-employed filer who guessed low now hands back every dollar instead of stopping at $1,625.
A Roth conversion is ordinary income, and Social Security counts it when it sets your Medicare Part B and Part D premiums two years later. For 2026 premiums the first joint threshold is $218,000, and crossing it by a dollar costs a married couple $2,296.80.
For 2026 the 20% pass-through deduction starts phasing out at $201,750 of taxable income for singles and $403,500 for joint filers, and for service businesses it hits zero at $276,750 and $553,500. The One Big Beautiful Bill widened the band, so the deduction now falls more slowly.
For 2026 the QCD limit rises to $111,000 per person. Sent straight from your IRA to a charity, it satisfies your required minimum distribution and never lands in your adjusted gross income, which a normal donation cannot do.
The One Big Beautiful Bill made 100% bonus depreciation permanent, but only for property acquired after January 19, 2025. Sign the contract a day early and you are capped at 40%. The date you committed to buy matters more than the date the asset shows up.
A trust hits the top 37% bracket at just $16,000 of income in 2026, plus a 3.8% surtax. The 65-day rule lets you move that income onto a beneficiary's return at a lower rate, if you distribute in time and check the box on Form 1041.
The One Big Beautiful Bill created a deduction of up to $10,000 a year for interest on a new car loan, but only for a vehicle with final assembly in the United States. The write-off phases out above $100,000 of income and requires the VIN on your return.
