Tips to Maximize Your Take-Home Pay in South Carolina
- Contribute to a 401(k) or 403(b) — Pre-tax retirement contributions reduce both your federal and state taxable income (up to $23,500 for 2025).
- Use a Health Savings Account (HSA) — If eligible, HSA contributions (up to $4,300 individual / $8,550 family in 2025) are tax-deductible at both federal and state levels.
- Review your W-4 — Make sure your withholding allowances match your actual tax situation to avoid over-withholding.
- Consider itemized deductions — If your mortgage interest, state/local taxes (up to $10,000 SALT cap), and charitable contributions exceed the standard deduction, itemizing could save you money.
