📈 Smart Tax Planning Strategies to Boost Your Future Benefits
1. Don’t Underreport Your Income
While deducting expenses reduces taxable income, underreporting profits can reduce your lifetime Social Security benefits. Aim to report a consistent and realistic level of income year after year.
2. Plan for Full 35 Years of Earnings
The Social Security Administration uses your 35 highest-earning years to calculate benefits. Years with no income will be counted as zero and reduce your benefit, so consider keeping your business active even part-time to fill in missing years.
3. Maximize Earnings Up to the Cap
For 2025, only the first $168,600 of self-employment income is subject to Social Security tax. If you’re able to reach or approach this cap, your future benefits will be maximized.
4. Consider Delaying Retirement
Delaying your Social Security benefit past full retirement age (FRA) can boost your monthly check by up to 8% annually. Continue self-employment beyond FRA to boost your average earnings and take advantage of delayed retirement credits.
5. Use Estimated Tax Payments
Pay self-employment tax quarterly using Form 1040-ES to avoid penalties and stay on track. You’ll also avoid year-end surprises and ensure your Social Security credits are properly reported.
