California and New Jersey Tax the $4,400 a $65,000 Filer Puts in an HSA for 2026

· 6 min read

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 the 2026 tax year, eight states tax some Social Security benefits: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah and Vermont. Pension and IRA rules spread wider, from Illinois, which subtracts every retirement dollar at any age, to California, which taxes all of it.

Taxpayers 65 and older deduct an extra $6,000 each through 2028, stacked on the standard deduction and the age-65 addition: for 2026 the layers total $24,150 for a single filer and $47,500 for a couple who are both 65. 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).

Section 530A builds the Trump Account as a traditional IRA for children: a one-time $1,000 Treasury deposit for children born 2025 through 2028, after-tax contributions capped at $5,000 a year, and ordinary income tax on the earnings at withdrawal. Growth is tax-deferred, and the widely reported 'tax-free' label is wrong.

Illinois's Tax Overhaul Never Touched the Flat 4.95%

· 6 min read

Illinois's overhaul of apportionment and foreign-income deductions lives on corporate schedules; the IL-1040 still charges a flat 4.95%, unchanged since July 2017 and constitutionally required to stay non-graduated. What moves an Illinois bill is the exemption allowance ($2,925 for 2026, gone in one step above $250,000 of AGI), the retirement subtraction, and the 5% property tax credit.
