Delaware's Progressive Income Tax Brackets
Delaware uses 7 tax brackets ranging from 0% to 6.6%, with a $3,250 standard deduction. The top 6.6% rate kicks in at $60,000 of taxable income. Like the federal system, Delaware's brackets are marginal — only income within each range is taxed at that bracket's rate. An $85,000 earner in Delaware pays an effective state rate well below 6.6% because the first dollars flow through lower brackets. The bracket visualization in the calculator above shows exactly how your income is distributed across Delaware's brackets.
Local Income Taxes in Delaware
Several Delaware jurisdictions levy their own income taxes on top of the state rate: Wilmington: 1.25% flat rate. These local taxes can add $1,000-$5,000+ to your annual tax bill depending on income level and jurisdiction. The calculator above includes all 1 local tax jurisdictions we track for Delaware — select your city or county from the dropdown to see the combined impact. If you're considering relocating within Delaware, the local tax difference between jurisdictions can shift your take-home pay by $50-$200+ per paycheck.
Maximizing Your Take-Home Pay in Delaware
The most effective lever for increasing take-home pay in Delaware is pre-tax retirement contributions. A traditional 401(k) contribution reduces your taxable income for both federal and state taxes. At $85,000 in Delaware, your combined marginal rate (federal + state) is approximately 29%. Every $100 directed to a pre-tax 401(k) saves $29 in taxes — you sacrifice $71 in take-home pay, not $100. HSA contributions (if you have a high-deductible health plan) go further — they reduce federal, state, AND FICA taxes, saving roughly 37% on every contributed dollar.

How are Social Security and Medicare taxes calculated on my Delaware paycheck?
FICA taxes are federal — they're the same in every state. Social Security: 6.2% on wages up to $176,100 ($10,918 max/year). Medicare: 1.45% on all wages, plus an additional 0.9% on wages above $200,000. On $85,000, FICA totals $6,502/year ($250/biweekly paycheck). FICA is calculated on gross wages before any deductions — pre-tax 401(k) and health insurance contributions don't reduce FICA. Your employer pays a matching 7.65% on top of what you see on your pay stub.
