Nothing slashes an April headache like a December plan. Below you’ll find the year-end tax-saving money moves for freelancers, small-business owners, and W-2 pros—each totally legal, fast to implement, and laser-focused on 2025 rules.
1. Year-End Tax-Saving Money Moves for Freelancers
| Move | Deadline | How It Works | Tax Impact |
|---|---|---|---|
| Load a SEP-IRA | 4/15/26 (fund ASAP) | Up to 20 % of net Schedule C profit, max $69 k. | Lowers AGI; may trim QBI phaseouts. |
| Prepay deductible expenses | 12/31/25 | Buy 2026 supplies & software now (cash basis). | Pulls write-offs into 2025. |
| Invoice early / defer cash | 12/31/25 | Bill Dec 15, request Jan 2 payment. | Shifts revenue to 2026. |
| Fund an HSA | 4/15/26 | $4,300 single / $8,550 family (+$1 k catch-up 55+). | Deduction, tax-free growth & use. |
2. Retirement-Account Money Moves to Maximize Tax Deductions
| Account | 2025 Limit | Catch-Up (50+) | Deadline (2025) |
|---|---|---|---|
| 401(k) / 403(b) / TSP | $23,500 | $7,500 (60-63: $11,250) |
12/31 payroll |
| Traditional / Roth IRA | $7,000 | $1,000 | 4/15/26 |
| HSA (self / family) | $4,300 / $8,550 | $1,000 (55+) | 4/15/26 |
