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.
Frequently asked questions
What can self-employed plumbers deduct on their taxes?
Self-employed plumbers can deduct tools, equipment, pipe and fittings inventory, work vehicle expenses, license fees, bonding and insurance costs, safety gear, advertising, and a home office if used exclusively for business. Section 179 expensing allows full deduction of qualifying equipment purchases (like drain cameras or pipe threaders) in the year of purchase rather than depreciating over time.
How do plumbers deduct vehicle expenses?
Self-employed plumbers can choose between the standard mileage rate (70 cents per mile in 2025) or actual vehicle expenses (fuel, insurance, repairs, depreciation). For work vans and trucks carrying tools and materials, the actual expense method is often more beneficial. Keep a detailed mileage log for all business trips between job sites. Commuting from home to a regular shop location is not deductible.
Should plumbers set up a retirement plan?
Self-employed plumbers should consider a SEP-IRA (contribute up to 25% of net self-employment income, max $70,000 in 2025) or a Solo 401(k) for even higher contribution limits. Union plumbers often have multi-employer pension plans and annuity funds. Contributing to retirement accounts reduces taxable income dollar-for-dollar and builds long-term wealth.
Should I choose Roth or Traditional for my retirement accounts?
At the 12-22% bracket, Roth contributions are often advantageous because you pay tax at a historically low rate now and withdraw tax-free later. 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.
