Delaware Paycheck Calculator

Delaware's income tax uses six brackets — 2.20%, 3.90%, 4.80%, 5.20%, 5.55%, and 6.60% — and unlike most progressive-tax states on this site, the dollar thresholds for each bracket are identical regardless of filing status. Multiple independent sources confirm this directly: Delaware simply doesn't widen (typically doesn't double) its bracket thresholds for married filing jointly the way a state like Kansas or Nebraska does.

The practical consequence is a genuine marriage-penalty effect: a married couple filing jointly reaches the same $60,000 top-bracket threshold that a single filer would reach alone, meaning two working spouses with combined income above that level pay tax at Delaware's top 6.60% rate on a meaningfully larger share of their combined income than they would if each could somehow file as an independent single filer at half the income.

This is the same structural pattern seen in Rhode Island's unwidened brackets elsewhere on this site, though Delaware's effect is arguably more pronounced given its six-bracket schedule spans a wider range of rates than Rhode Island's three-bracket structure.

Delaware's rate schedule has a subtle feature worth understanding: the lowest 2.20% bracket doesn't begin at $0 of taxable income — it begins at $2,000. That means the first $2,000 of taxable income (after the standard deduction has already been subtracted) is effectively untaxed, a small built-in zero-bracket similar in spirit, though much smaller in scale, to North Dakota's much larger 0% bracket elsewhere on this site.

Combined with Delaware's $3,250 single standard deduction, this means a Delaware filer's first $5,250 of gross income ($3,250 deduction + $2,000 zero-bracket) faces no state income tax at all, before the 2.20% rate begins to apply on the next slice.

This calculator's bracket configuration starts the first rate tier at the $2,000 threshold directly, matching Delaware's own published rate schedule rather than assuming every bracket schedule starts its lowest rate immediately at $0 the way most other states on this site do.

This calculator's Delaware figures cover federal income tax, Delaware's six-bracket state income tax, and the two federal FICA taxes — the complete set of withholding categories that apply broadly to Delaware wage earners. Delaware has no state-run disability insurance or paid-family-leave payroll premium as of 2026, unlike states such as Colorado, Rhode Island, or Maine that layer a genuine second payroll deduction on top of income tax.

Delaware does not levy statewide local income taxes on top of the state rate for most residents, but Wilmington is the one real exception: it levies its own 1.25% City Wage Tax on both residents and non-residents whose income is earned within city limits, a figure confirmed across multiple independent payroll-tax reference sources. That is a genuine local-tax gap this calculator does not model — the engine has no Wilmington-specific input or bracket — similar in spirit to the local-tax disclosures for Missouri and Maryland elsewhere on this site.

A worker comparing take-home pay for a job specifically within Wilmington should manually add roughly 1.25% of their Wilmington-sourced wages on top of the numbers shown here, since this calculator's stateTax figure reflects Delaware's statewide income tax only and stops there.
