Your federal marginal rate is 22.0% and your Missouri marginal rate is 4.8%.
Tax Environment in Missouri
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
At $80,000 to $130,000 you are solidly in the 22% bracket, with some high-end earners touching the 24% bracket at $103,350 taxable income (about $119,000 gross). FICA remains a significant tax — at $100,000, you pay $7,650 in Social Security and Medicare combined. This is the income range where maximizing tax-advantaged accounts, Health Savings Accounts, and the Child Tax Credit have the most impact on your overall tax bill.
Max out tax-advantaged accounts
Between 401(k) ($23,500), IRA ($7,000), and HSA ($4,300 individual / $8,550 family), you can shelter up to $35,000+ from federal income tax. At the 22% bracket, that is over $7,700 in annual tax savings. Prioritize the 401(k) match first, then HSA, then IRA, then additional 401(k). Use calculator →
Health Savings Account (HSA)
If you have a high-deductible health plan, the HSA is the most tax-efficient account available — contributions are pre-tax, growth is tax-free, and withdrawals for medical expenses are tax-free. The 2025 limit is $4,300 (individual) or $8,550 (family). Unlike FSAs, HSA funds roll over indefinitely. Use calculator →
Child Tax Credit
Each qualifying child under 17 gives you a $2,000 credit that directly reduces your tax bill. With two children, that is $4,000 off your federal tax. The credit starts phasing out at $200,000 (single) or $400,000 (MFJ), so you receive the full amount at this income level. Use calculator →
Typical roles at this level: Experienced professionals, mid-career engineers and developers, accountants, registered nurses, project managers, federal employees at GS-11 to GS-13, and small business owners.
