Tax Environment in South Carolina
This state uses a progressive income tax system with multiple brackets, similar to the federal system. Only the income within each bracket is taxed at that rate, so your effective state rate is lower than the top bracket. Tax planning strategies include maximizing pre-tax retirement contributions to reduce state-taxable income.
Tip: In a progressive-bracket state, pre-tax 401(k) and HSA contributions reduce your state tax bill along with federal tax. If you are near a bracket boundary, an additional contribution can drop you into a lower state bracket.

What to know at this income level
Between $45,000 and $80,000, most of your taxable income falls in the 12% bracket with some crossing into the 22% bracket at $48,475 (single, after standard deduction starts around $64,000 gross). This is the income range where the US median household income sits (~$80,000 in 2024), so you are in the mainstream of American earners. Tax-advantaged retirement accounts — 401(k) and IRA — become your most effective tax planning tools.
22% bracket threshold
The 22% bracket starts at $48,475 of taxable income (about $64,000 gross salary for single filers). Each dollar above this threshold costs 10 cents more in tax than the 12% bracket below it. Contributing to a pre-tax 401(k) can keep more income in the 12% bracket. Use calculator →
Pre-tax 401(k) strategy
At the 22% bracket, every $1,000 contributed to a pre-tax 401(k) saves $220 in federal tax immediately. The 2025 limit is $23,500. If you cannot max it out, aim for at least the employer match — typically 3-6% of salary. Use calculator →
Roth vs Traditional IRA
At the 12-22% bracket range, a Roth IRA may be optimal. You pay tax now at a relatively low rate and withdraw tax-free in retirement when you may be in a higher bracket. The 2025 IRA contribution limit is $7,000 ($8,000 if age 50+). Use calculator →
Typical roles at this level: Mid-level office and administrative workers, skilled trades, teachers, police officers, retail managers, and early-career professionals in most fields.

Should I choose Roth or Traditional for my retirement accounts?

If you expect higher income in retirement (pensions, Social Security, investment income), Roth is especially compelling. Traditional pre-tax contributions make more sense if you need the immediate tax deduction to manage cash flow.
