You could save real money with an S-Corp
After ~$1,200–$2,500 in payroll and filing costs, that's about $1,556–$2,856 net — likely worth electing, as long as the salary stays reasonable.

What freelancers actually owe
Does Delaware tax self-employment income?
Yes. Delaware taxes self-employment income at 2.2%–6.6%, on top of your federal tax. Delaware taxes your business profit as ordinary income, stacked on top of the federal self-employment tax and federal income tax.
The estimate above combines all three: federal income tax, federal self-employment tax, and Delaware state income tax — so you can see your full Delaware picture in one number.
What you owe as a Delaware freelancer
First, federal: self-employment tax of 15.3% on 92.35% of net profit, plus federal income tax after the standard deduction and 20% QBI deduction.
Then Delaware state income tax starting at 2.2%. Note that Delaware doesn't offer the 20% QBI deduction, so your state taxable income is higher than your federal taxable income — this tool accounts for that.
Your 2026 quarterly due dates
Federal estimated taxes are due four times a year (shown above). Delaware exempts the first $2,000 of income. Wilmington residents owe an additional 1.25% city wage tax not included here.
Would an S-Corp help in Delaware?
An S-Corp cuts the 15.3% self-employment tax on the profit you take as distributions instead of salary — a federal saving that applies in Delaware too. Use the comparison above to weigh it against the $1,200–$2,500 yearly cost of payroll and a separate return.
