- What are Delaware income tax brackets for 2026?
- Delaware has 6 brackets for single filers, starting at 2.2% and reaching 6.6% at the top. The full table is listed above, with the standard deduction subtracted before those rates apply.
- What is the top Delaware income tax rate?
- The top Delaware rate is 6.6%, and it only applies to income above the highest bracket threshold shown above — not to your whole salary. The rate on your first dollars is 2.2%.
- What is the Delaware standard deduction for 2026?
- $3,250 for single filers and $6,500 for married couples filing jointly; there is no separate dependent exemption. Taxable income is what remains after that deduction, and it is what the brackets are applied to.
- What is the take-home pay on $100,000 in Delaware?
- For a single filer paid biweekly with no 401(k) deferral and no health premiums, a $100,000 salary in Delaware leaves $2,838.88 per paycheck — $73,811.00 a year, an effective rate of 26.2% after $13,170 of federal income tax, $5,369 of Delaware tax and $7,650 of FICA.
- Do remote workers pay Delaware income tax?
- A Delaware resident is generally taxed by Delaware on wages earned anywhere, including wages for a remote job whose employer sits in another state. Days worked physically outside Delaware can matter in some cases, and a non-resident working in Delaware is generally taxed on income earned here. Nothing here is tax advice — the details depend on your situation.
- Does Delaware have local income taxes?
- Wilmington has a 1.25% wage tax; New Castle County a 1.25% county option tax. This calculator does not model that layer — treat the number above as state plus federal only.
