Delaware S-Corp Tax Calculator

In Delaware, electing S-corp status can cut your self-employment tax by paying yourself a reasonable salary and taking the rest as distributions. Delaware charges an LLC $300 a year whether or not it elects S-corp, so the election adds no state cost and this calculator counts none. At a 60% salary and $2,500 a year of overhead, and counting the income tax the salary changes as well as payroll tax, it pays off between $57,263 and $222,474 of net profit, and again from $263,978 — above $222,474, the salary is still paying Social Security tax after a sole proprietor's has stopped at the wage base; from $263,978, the QBI wage limit takes the deduction from a sole proprietor with no payroll, and the salary keeps it. Below $263,978 of net profit, it never saves more than about $1,934 a year at these assumptions.

That assumes a salary of 60% of net profit (capped at the $184,500 Social Security wage base), $2,500 a year for payroll and the extra business return, a single filer with no other income taking the $16,100 standard deduction, a business that is not a specified service business (not consulting, law, health, financial services and the like) and an LLC you already have, so its annual fee is paid either way. It counts federal payroll tax and federal income tax (including the QBI deduction the salary changes). Your own state income tax is not in it.

The rules

Delaware self-employment & S-corp rules

  • State income tax: up to 6.6%. Self-employment tax itself (15.3%) is federal and identical in every state.
  • Annual LLC fee: Delaware charges an LLC $300 a year whether or not it elects S-corp, so the election adds no state cost and this calculator counts none.
  • Also note: Delaware imposes a gross-receipts tax on in-state business, regardless of entity type — not modeled in the savings above.
  • PTET (SALT-cap workaround): Delaware hasn't enacted a PTET election — but the federal S-corp self-employment-tax savings shown above still apply.
  • Strong LLC privacy + corporate-friendly courts make it a popular incorporation state — but Delaware LLC formation does NOT exempt you from your home state's tax obligations.
Questions

Frequently asked questions

How much self-employment tax will I pay in Delaware?
Self-employment tax is federal — 15.3% (12.4% Social Security up to the $184,500 wage base + 2.9% Medicare) on 92.35% of your net self-employment income, the same in Delaware as everywhere. Delaware then taxes that same income at its state income-tax rate (up to 6.6%). The calculator above shows your SE tax at any income.
Is an S-corp worth it for a Delaware freelancer or LLC owner?
In Delaware, at this calculator's default assumptions, it pays off between $57,263 and $222,474 of net profit, and again from $263,978 — above $222,474, the salary is still paying Social Security tax after a sole proprietor's has stopped at the wage base; from $263,978, the QBI wage limit takes the deduction from a sole proprietor with no payroll, and the salary keeps it. Below $263,978 of net profit, it never saves more than about $1,934 a year at these assumptions. That assumes a salary of 60% of net profit (capped at the $184,500 Social Security wage base), $2,500 a year for payroll and the extra business return, a single filer with no other income taking the $16,100 standard deduction, a business that is not a specified service business (not consulting, law, health, financial services and the like) and an LLC you already have, so its annual fee is paid either way. It counts federal payroll tax and federal income tax (including the QBI deduction the salary changes). Your own state income tax is not in it. A lower defensible salary moves the answer, and so do your own payroll and return quotes.
Does Delaware have a PTET (SALT-cap workaround)?
Delaware does not currently offer a pass-through entity tax (PTET) election, so the federal SALT cap ($40,400 for 2026, phasing down toward $10,000 above ~$505,000 of MAGI) applies to state taxes paid personally.
How is my "reasonable salary" set for an S-corp?
The IRS requires S-corp owner-employees to pay themselves a reasonable salary (subject to FICA) before taking distributions. This calculator assumes a salary of 60% of net profit (capped at the $184,500 Social Security wage base), with the rest taken as distributions, as an illustration — your actual reasonable compensation depends on your role and industry and should be set with a CPA.
