Self-Employed Tax Calculator — Delaware (2026)
Self-employed in Delaware? Your tax bill has three layers that a W-2 employee never sees in full: 15.3% self-employment tax on 92.35% of net profit, federal income tax, and Delaware state income tax. This calculator applies all three to your 2026 net profit and shows the quarterly amount you should be setting aside. Delaware uses a progressive income tax with 7 brackets running from 0.00% up to 6.60%, applied after a state standard deduction of $3,250.

Self-employment tax vs Delaware income tax
Self-employment tax is federal and identical in all 50 states: 12.4% Social Security up to $184,500 of net earnings plus 2.9% Medicare with no cap. Half of it is deductible against income tax, which is why the calculator subtracts it before applying brackets.
Delaware then taxes essentially the same profit figure at 0.00%–6.60%. On $80,000 of net profit that adds roughly $3,676 to the bill.
Wilmington residents pay an additional 1.25% city wage tax.
Deductions that matter for Delaware freelancers
Net profit — not gross revenue — drives every number here. Ordinary and necessary business expenses reduce SE tax, federal tax, and Delaware tax simultaneously: the 2026 standard mileage rate of $0.67/mile, home-office square footage, software, equipment, professional insurance, and the self-employed health insurance deduction.
Retirement plans go further. A SEP-IRA or solo 401(k) reduces income tax (though not SE tax) and is often the largest single deduction available to a profitable banking contractor in Wilmington.
Working for yourself in Delaware
Delaware's economy leans on banking, chemicals, and legal services, which shapes the contractor market around Wilmington — and your fixed costs. With one-bedroom rent near $1,400, a freelancer needs meaningfully more gross revenue than an employee to reach the same lifestyle, because there is no employer paying half of FICA.
Delaware has no state or local sales tax — one of only five 'NOMAD' states with zero sales tax.
Local and payroll taxes Delaware adds on top
Delaware Paid Leave contributions of roughly 0.4% are split with your employer. That deduction sits outside the federal and state income tax lines, so build it into your own budget on top of the numbers above.
Wilmington residents pay an additional 1.25% city wage tax.
Nobody withholds these for you when you are self-employed in Delaware. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from Delaware
Delaware has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Wilmington resident spending part of the year at a client site in Pennsylvania may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Delaware tax bill
Delaware charges no general sales tax, homeowners pay an average effective property tax of 0.58% of market value, and the minimum wage in force during 2026 is $15.00 an hour.
No sales tax at all; a gross receipts tax falls on businesses instead.
Income tax is only one part of a state's take. Delaware recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Delaware excludes up to $12,500 of pension and retirement income at 60+ and does not tax Social Security.
Delaware vs Pennsylvania on the same salary
On a $90,000 salary, a single filer keeps about $67,436 a year in Delaware against roughly $69,382 in Pennsylvania — a difference of $1,946, or $162 a month.
Effective combined rates are 25.1% in Delaware and 22.9% in Pennsylvania. Set that gap against living costs: index 101 here versus 95 there, with property tax at 0.58% and 1.49% respectively.
