How this calculator works
Like the Texas calculator, this estimates federal tax and FICA the same way; Delaware doesn’t change those. On top of that, it computes Delaware’s own state income tax: a flat standard deduction ($3,250 single, $6,500 joint), Delaware’s own seven-bracket rate table (0% to 6.6%, with dollar thresholds that stay the same whether you file single or jointly), and then a $110-per-exemption personal credit subtracted directly from the computed tax.
The formula
(federal tax, FICA, and net-pay assembly are identical to the Texas calculator)
deTaxableIncome = max(0, wagesAfterPretax − deStandardDeduction)
($3,250 single / $6,500 joint)
deGrossTax = 2026 DE bracket schedule applied to deTaxableIncome
(0% / 2.2% / 3.9% / 4.8% / 5.2% / 5.55% / 6.6%,
SAME dollar thresholds for single and joint filers)
dePersonalCredit = $110 × number of personal exemptions
(1 single, 2 joint — no dependents modeled)
deIncomeTax = max(0, deGrossTax − dePersonalCredit)
stateTax = deIncomeTax
Worked example
A single filer earning $60,000/year, paid biweekly, with no 401(k) or extra deductions:
- FICA: $4,590.00/year (same as any state)
- Federal tax: $5,020.00/year (same as any state)
- Delaware taxable income: $60,000 − $3,250 standard deduction = $56,750
- Delaware gross tax: $1,001.00 (cumulative tax through $25,000) + 5.55% × $31,750 = $1,001.00 + $1,762.13 = $2,763.13
- Delaware personal credit: 1 exemption × $110 = $110.00
- Delaware income tax: $2,763.13 − $110.00 = $2,653.13/year
- Net pay: $60,000 − $4,590 − $5,020 − $2,653.13 = $47,736.87/year, or $1,836.03 per biweekly paycheck
We cross-checked this against SmartAsset’s Delaware Paycheck Calculator for the same inputs (accessed 2026-08-25): it showed a gross paycheck of $2,308, Delaware state income tax of $102/period (4.42%, about $2,652/year), federal tax of $195/period, and a combined “FICA and State Insurance Taxes” line of exactly 7.65% (plain FICA, confirming that tool doesn’t add any extra Delaware payroll tax either). Our state-tax figure is within about $1/year of that estimate, and the small remainder is the same annual-liability-vs-per-paycheck-withholding gap described on our Texas calculator.
Frequently asked questions (FAQ)
Why doesn't Delaware's standard deduction change based on how much I earn?
Some states, like Alabama, shrink the standard deduction as income rises. Delaware doesn't: it's a flat $3,250 for single filers or $6,500 for joint filers, no matter your income. The only thing that changes it is your filing status, not how much you earn.
What is Delaware's "personal credit," and how is it different from a deduction?
A deduction reduces the income you're taxed on, before the bracket math runs. Delaware's personal credit is applied the opposite way: it's a flat $110 per exemption (1 for single, 2 for joint filers) subtracted directly from your computed tax, after the brackets have already been applied.
Do Delaware's tax brackets double for married couples filing jointly?
No, and this is unusual. Most states with brackets (like California and Connecticut) double every dollar threshold for joint filers. Delaware doesn't: the same $0-$2,000, $2,000-$5,000, and so on thresholds apply whether you file single or jointly. Only the standard deduction and personal credit change by filing status.
Does Wilmington add its own city income tax on top of Delaware's state tax?
Yes, if you live or work in Wilmington. It's the only Delaware municipality with a local income tax: a flat 1.25% on earned income, charged to both residents and nonresidents who work there. This calculator doesn't include it, so a Wilmington worker's actual take-home pay will be a bit lower than shown here.
Is Delaware Paid Leave taken out of my paycheck?
It can be, but the amount isn't fixed by law the way it is in some other states. Delaware Paid Leave costs 0.8% of wages total, split between employer and employee; your employer can deduct up to 0.4% from your paycheck, or choose to cover some or all of that themselves. This calculator doesn't model it since there's no single guaranteed rate.
Are tips and overtime tax-free in Delaware?
No. The federal 2025-2028 "no tax on tips" and "no tax on overtime" deductions only reduce your federal taxable income. Delaware has not adopted matching state deductions, so tips and overtime remain fully taxable on your Delaware return.
