Delaware Income Tax Calculator

Calculate your Delaware state income tax using the official 2024 brackets.

Compute Delaware state income tax using the current progressive brackets from 0% to 6.6%, the standard deduction, the extra age-65 deduction, itemized deductions, and the $110 personal credit per exemption. Shows marginal and effective rates.

What are Delaware's income tax brackets?

Delaware uses seven progressive brackets: 0% on the first $2,000, 2.2% up to $5,000, 3.9% up to $10,000, 4.8% up to $20,000, 5.2% up to $25,000, 5.55% up to $60,000, and a top rate of 6.6% on income over $60,000. The same brackets apply to single and married-joint filers.

The Delaware Income Tax Calculator computes your Delaware state income tax using the state’s seven progressive brackets, the standard or itemized deduction, and the $110 personal credit per exemption. Delaware’s top rate of 6.6% kicks in at just $60,000 of taxable income, and uniquely the brackets are the same for single and married-joint filers, which makes Delaware’s structure simpler than the federal one.

How it works

The calculation follows Delaware Form 200-01:

  1. Deduction — subtract the larger of your itemized deductions or the standard deduction ($3,250 single / $6,500 married-joint), plus an extra $2,500 if you are 65+ or blind, to get Delaware taxable income.
  2. Bracket tax — apply the progressive rates to taxable income. Each slice of income is taxed at its own rate; only the portion above $60,000 is taxed at the top 6.6%.
  3. Personal credits — subtract $110 per exemption directly from the tax. This is a credit, not a deduction, so it reduces the tax dollar-for-dollar (but not below zero).

The brackets

$0      – $2,000   : 0.00%
$2,001  – $5,000   : 2.20%
$5,001  – $10,000  : 3.90%
$10,001 – $20,000  : 4.80%
$20,001 – $25,000  : 5.20%
$25,001 – $60,000  : 5.55%
over    $60,000    : 6.60%

Example

A single filer with $65,000 of income subtracts the $3,250 standard deduction for $61,750 of taxable income. The bracket tax is about $3,151, and one $110 personal credit lowers it to roughly $3,041 — an effective rate near 4.7% even though the marginal rate is 6.6%.
