Use the corrected 2026 SALT limits
For tax year 2026, the IRS states that the overall limit on the itemized deduction for state and local taxes is $40,400, or $20,200 for a married taxpayer filing separately. The limit begins to decrease when modified adjusted gross income exceeds $505,000, or $252,500 for married filing separately.
The IRS says the reduced limit cannot fall below $10,000, or $5,000 for married filing separately. These figures are deduction ceilings, not automatic deductions or dollar-for-dollar tax credits. The allowable amount still depends on eligible taxes, filing status, income, and whether itemizing is advantageous under the applicable rules.
Start with the 2026 filing baseline
The IRS lists 2026 standard deductions of $32,200 for married couples filing jointly, $16,100 for single filers and married taxpayers filing separately, and $24,150 for heads of household. Tax-year 2026 amounts generally apply to returns filed in 2027.
Collect current records before comparing the standard deduction with permitted itemized deductions. A larger deduction does not reduce tax by the same dollar amount, and the option that produces the lower liability depends on the full return rather than a single expense category.
Retirement limits are not universal deductions
For 2026, the employee elective-deferral limit for 401(k), 403(b), and governmental 457 plans is $24,500, while the annual IRA contribution limit is $7,500 before any applicable age-based catch-up amount. A contribution limit is not a recommendation to contribute that amount.
Tax treatment varies by account type and taxpayer circumstances. Roth IRA contributions are not deductible, Traditional IRA deductibility can be limited, workplace-plan contributions depend on plan terms, and income-based eligibility rules can apply. Confirm the current IRS rule and the account’s terms before moving money.
Use a documentation-first year-end review
Review filing status, expected income, withholding or estimated payments, eligible deductions and credits, account contribution records, and any major life or business changes. Keep source documents and note the tax year to which each payment or contribution applies.
Tax outcomes are highly fact-specific. For questions involving business income, multiple states, equity compensation, retirement-plan eligibility, or a large change in income, a credentialed tax professional can apply the current law to the complete facts.
