SALT Cap and AMT: What High Earners Need to Know in 2026
The SALT cap and AMT are two of the most significant tax provisions affecting high earners - and both frequently create unexpected tax bills.
The SALT Cap
SALT stands for State and Local Taxes. Before the $10,000 cap, these were fully deductible on your federal return. A California resident paying $25,000 in state income taxes can only deduct $10,000 federally - the other $15,000 gets no federal benefit.
The bottom line
For high earners in California, New York, and New Jersey, the SALT cap effectively raises their federal tax bill by thousands per year.
The Standard Deduction vs. Itemizing
The 2026 standard deduction is $32,200 for married filing jointly. With SALT capped at $10,000, many high earners find their itemized deductions are close to or below the standard deduction - meaning mortgage interest and charitable giving provide little additional benefit.
Charitable Bunching
The Alternative Minimum Tax
AMT is a parallel tax calculation - you compute taxes under both the regular system and AMT, and pay whichever is higher.
What would you do?
Priya earns $290,000 and lives in California. She has a mortgage with $18,000 in interest, $25,000 in state income taxes paid, and $8,000 in charitable donations.
Your Move
Add your mortgage interest + property taxes + state income taxes (capped at $10,000 SALT total) + charitable contributions. If above $32,200 (MFJ) or $16,100 (single), itemizing is likely beneficial. If below, charitable bunching may help.
