What is the 2026 SALT deduction cap?
The new SALT deduction cap for 2026 is $40,400. This allows taxpayers in high-tax states to deduct significantly more state and local taxes from their federal returns.
How do I calculate salt cap loss or gain?
To calculate your gain, subtract the old $10,000 limit from your total eligible taxes (up to $40,400) and multiply by your federal tax bracket.
Does this apply to NY and CA residents?
Yes, California and New York residents benefit most because their combined property and state income taxes often exceed the previous $10,000 threshold.
