What changed by line
Line 5e now limits state and local income, sales and property taxes to $40,000, or $20,000 married filing separately. The limit shrinks once modified AGI passes $500,000 ($250,000 married filing separately), but not below $10,000 ($5,000 married filing separately).
The IRS says the tips, overtime, car loan interest and senior deductions are claimed on Schedule 1-A, not Schedule A, even for clients who itemize. Line 8d on the 2025 form is still marked reserved for future use.
