The Qualified Business Income deduction (20% deduction on qualified business income) was enacted in 2017 and is set to expire after December 31, 2025, unless Congress extends it. If not extended, self-employed workers will lose a significant income tax reduction starting in 2026. Watch for legislative developments.
Impact of the Higher SS Wage Base
The $7,500 increase in the Social Security wage base means self-employed workers earning between $168,600 and $176,100 now pay the full 15.3% SE tax on an additional $7,500 of income in 2025 (vs. 2.9% in 2024). Maximum additional SE tax: $7,500 × (12.4% Social Security component) × 92.35% = approximately $860 more for high earners.
What This Means for Quarterly Payments
For most freelancers: adjust quarterly estimates for the slightly higher retirement contribution limits and slightly higher standard deduction. The net effect for most is a modest reduction in taxable income and slightly lower income tax (but unchanged SE tax rate). Recalculate your quarterly payment in Q1 2025 using the updated parameters.
