How Delaware State Income Tax Works

Delaware uses a progressive bracket system with seven brackets ranging from 0% to 6.6% in 2026. For a full annual breakdown, see our Delaware income tax calculator. Like the federal system, only the dollars within each bracket are taxed at that bracket's rate — your marginal rate applies to the next dollar earned, while your effective rate (total tax ÷ income) is always lower.

• Standard deduction — $3,250 single / $6,500 MFJ / $3,250 married filing separately / $3,250 head of household. Significantly smaller than the federal standard deduction, meaning more of your income is taxable at the state level.
• Personal exemption credit — $110 per exemption (single filers claim 1, MFJ claim 2), applied directly as a credit against tax owed. Plus $110 per dependent. Note this is a credit, not a deduction.
• 401(k) and Section 125 deductions — pre-tax for both federal and DE state income tax. They reduce your state taxable wages before brackets apply.

The Wilmington City Wage Tax

Wilmington, Delaware is one of the few mid-Atlantic cities to impose a local income tax. The Wilmington city wage tax is 1.25% on all earned income, and — unlike most city income taxes — it applies to both residents and non-residents working within city limits.

Who Owes the Wilmington Wage Tax?

• Wilmington residents: 1.25% on all earned income, regardless of where you work.
• Non-residents who work in Wilmington: 1.25% on wages earned while physically working in Wilmington. Many Delaware corporate workers and financial industry employees who live in suburbs but work downtown are subject to this tax.
• Remote workers: If you work entirely from home outside Wilmington city limits, you do not owe the Wilmington wage tax — even if your employer is based in Wilmington.

For a worker earning $75,000/year inside Wilmington, the city wage tax adds $938/year (~$36/biweekly paycheck) on top of state and federal taxes.

FICA Taxes — Social Security and Medicare

FICA is federal and applies on every Delaware paycheck.

• Social Security: 6.2% on wages up to $176,100 (2025) or $184,500 (2026). No further withholding once you cross the wage base for the year.
• Medicare: 1.45% on all wages with no cap. Additional 0.9% Medicare surtax on wages above $200,000 single / $250,000 MFJ.
• Employer match: your employer matches Social Security and base Medicare; the Additional Medicare surtax is employee-only.

Step-by-Step Example — $75,000 Delaware Single Filer (Outside Wilmington)

1. Gross annual pay: $75,000
2. Federal taxable income: $75,000 − $16,100 = $58,900. Federal tax: ~$5,765.
3. DE state taxable income: $75,000 − $3,250 (standard deduction) = $71,750.
4. DE state tax (before credit): 0% on $2,000 + 2.2% on $3,000 + 3.9% on $5,000 + 4.8% on $10,000 + 5.2% on $5,000 + 5.55% on $35,000 + 6.6% on $11,750 = approximately $3,530.
5. Subtract personal exemption credit: $3,530 − $110 = ~$3,420 DE state tax.
6. FICA: 7.65% on $75,000 = $5,738.
7. Net take-home: ~$60,077/year (~$2,311 biweekly).

How to Reduce Your Delaware Tax Withholding

Pre-tax payroll deductions save both federal and Delaware state income tax — a double-stacked benefit.

• Max your 401(k) — $23,500 in 2026 ($31,000 age 50+). A $20,000 contribution for a Delaware resident in the 22% federal / 5.55% DE bracket saves roughly $5,510 in total annual tax.
• Contribute to an HSA — $4,300 individual / $8,550 family in 2026. Delaware honors HSA contributions as pre-tax for state purposes.
• Use commuter benefits — up to $325/month in pre-tax transit/parking deductions reduces both federal and Delaware state tax.
• Adjust your Delaware withholding — use the Delaware Division of Revenue withholding calculator or update your state W-4 equivalent if your circumstances change. Compare your result with this paycheck calculator.
