Federal law stops the state you left from taxing your deferred compensation, but only if the plan pays it out over at least 10 years. Take the same balance in one check and California can bill the whole thing.
The One Big Beautiful Bill Act ended the 30% residential clean energy credit for expenditures made after December 31, 2025. Section 25D treats the expenditure as made when installation is completed, so a deposit paid in 2025 on a system finished in 2026 buys nothing.
Repaying a signing bonus in a later year does not undo the tax on its own. IRC §1341 offers a deduction or a credit, and on a $120,000 repayment the choice between them was worth $14,828.
Section 1042 defers every dollar of capital gains tax on a sale of company stock to an employee stock ownership plan, but only for C corporation stock. S corporation owners get nothing until sales after December 31, 2027, and then only on 10% of the proceeds.
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.
The One Big Beautiful Bill Act repealed the limits on repaying excess advance ACA subsidies for tax years beginning after 2025.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.
