The 2026 standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household. The estate and gift tax basic exclusion is $15 million per person, and the annual gift exclusion is $19,000.
For payments made in 2026, Form 1099-NEC and 1099-MISC are generally required only when payments to a payee reach $2,000, up from $600. The forms you file by February 1, 2027 are the first under the new threshold. Keep collecting W-9s from every contractor.
The SALT deduction cap rose to $40,000 starting with 2025 and increases 1% a year through 2029. It is reduced for higher incomes, but not below $10,000. Many California homeowners who stopped itemizing should recheck.
Qualifying property acquired and placed in service after January 19, 2025 can be fully expensed in the first year on the federal return. California does not conform. Section 179 expensing also rose, to $2.56 million for 2026.
The qualified opportunity zone program was made permanent, with a new round of zones and rules beginning in 2027. Investors with large capital gains should review timing.
