The federal return excludes a 2026 health savings account contribution of up to $4,400 for self-only coverage. California and New Jersey do not: a $65,000 single filer who contributes the maximum is still taxed by either state on all $65,000, whether the money went through payroll or not, and California taxes the account's earnings every year as well.

For tax year 2026 the $40,400 SALT cap loses 30 cents for every dollar of MAGI above $505,000 and lands on its $10,000 floor at $606,334. Inside that band an itemizer's next dollar of income is taxed as $1.30, a 45.5 percent federal rate in the 35 percent bracket.

The 2025 Schedule 1-A computes one modified AGI, runs the tip, overtime, car-loan-interest, and senior deductions through four separate phase-outs, and sends a single total to Form 1040 line 13b.

Each $6,000 shrinks by six cents per dollar of modified AGI over $75,000 ($150,000 joint) and is gone at $175,000 ($250,000 joint).

For tax years 2025 through 2028, up to $10,000 a year of interest on the loan behind a new, US-assembled, personal-use vehicle comes off taxable income on Schedule 1-A, stacked on the standard deduction.

The OBBBA added four temporary federal deductions, all claimed on new Schedule 1-A with or without itemizing: up to $25,000 of reported tips, $12,500 of overtime premium, $10,000 of car-loan interest, and $6,000 per filer 65 or older. None of them reduces AGI, and all four expire after 2028. The same law set the 2026 SALT cap at $40,400, the child tax credit at $2,200, and the estate exclusion at $15 million.
