Delaware state tax quick facts
  • Income tax: 0% - 6.6%
  • Sales tax: None
  • Property tax: 0.56% average effective rate
  • Gas tax: 23 cents per gallon of regular gasoline, 22 cents per gallon of diesel

Delaware’s state and local taxes are among the lowest in the nation. There is no state sales tax in Delaware, which makes it a popular place for holiday season shopping. It also has some of the lowest property taxes around: Delaware’s effective property tax rate of 0.56% ranks as the fifth lowest in the country. The most significant tax is the state income tax, with rates ranging from 0% for low earners to 6.6% for earners in the top income tax bracket.

Delaware Income Tax

The state of Delaware collects income taxes based on seven tax brackets, with rates ranging from 0% to 6.6%. Additionally, the city of Wilmington collects its own income tax, at a flat rate of 1.25%. For everyone who does not live or work in Wilmington, however, only the state tax is due. The table below shows tax brackets and rates for the Delaware income tax. Brackets are the same for all filing statuses.

Income Tax Brackets

All Filers
Delaware Taxable IncomeRate
$0 - $2,0000.00%
$2,000 - $5,0002.20%
$5,000 - $10,0003.90%
$10,000 - $20,0004.80%
$20,000 - $25,0005.20%
$25,000 - $60,0005.55%

A Delaware income tax return must be filed by any Delaware resident with a Delaware adjusted gross income (AGI) of $9,400 or more (for single filers or married persons filing separately) or $15,450 or more for joint filers.

Delaware AGI is very similar to federal AGI, but with a few differences. The largest difference is the state’s treatment of retirement income. Social Security income is not taxable in Delaware and can be subtracted from income, as can eligible income from a pension, up to a maximum of $2,000. Income from U.S. obligations (like U.S. Savings Bonds) can also be subtracted.

Itemized deductions in Delaware adhere to federal itemized deduction rules, and you can only claim itemized deductions if you did so on your federal tax return. The amount claimed on your federal return will be equal to the amount on your Delaware return, with a few small differences. For example, the credit for state and local taxes must be subtracted from the total if you claimed it on your federal taxes.

It you did not itemize deductions federally, then you can claim the Delaware standard deduction. That is $6,500 for joint filers and $3,250 for all other filers. For filers claiming the standard deduction, additional deductions of $2,500 may be claimed if either they or their spouse is 65 or older or blind.

Delaware Tax Credits

There are a number of income tax credits in Delaware that can be used to lower your total tax bill. The most significant is the personal credit, which is equal to $110 for every exemption claimed on your federal income tax return. So, for example, if you have exemptions for yourself, your spouse and two dependents, you would have a total personal credit of $440 (4 x $110). Additional credits of $110 may be claimed if you or your spouse is 60 or over.

Other commonly claimed credits include:

  • The Child Care Credit – 50% of the federal credit
  • The Earned Income Tax Credit – 20% of the federal credit
  • The Volunteer Firefighter’s Credit – $400 for active volunteer firefighters
  • Historic Preservation Tax Credit – available to residents who “promote community revitalization and restoration, and the rehabilitation of historic properties,” as certified by the Delaware State Historic Preservation Office

Delaware Capital Gains Tax

Most capital gains in Delaware are taxable at the full personal income tax rates listed above. This applies to both long- and short-term capital gains. However, gains realized from real estate sales in Delaware by those who live in another state are taxed at a rate of 6.6%. This rate applies to the gain less any selling expenses.

Delaware Sales Tax

Shoppers rejoice! There is no sales tax in Delaware.

If those rates have you thinking of purchasing a vacation home or a full-time residence in Delaware, read our Delaware mortgage guide for information on rates and getting a mortgage in the First State. There’s also valuable information for any current Delaware residents thinking of refinancing their home.

While there is no sales tax collected on purchases of alcohol in Delaware, some excise taxes still apply. These are generally close to or lower than the national averages, however. The tax on beer is 26 cents a gallon, or about 2.4 cents per beer. That’s the 24th highest rate in the U.S. The tax on liquor is $4.50 per gallon, 18th lowest in the country.

Places with the Lowest Tax Burden

Are you curious how your tax burden stacks up against others in your state? SmartAsset’s interactive map highlights the counties with the lowest tax burden. Scroll over any county in the state to learn about taxes in that specific area.

Rank County Income Tax Sales Tax Property Tax Fuel Tax


Where you live can have a big impact on both which types of taxes you have to pay each year and how much money you spend on them. SmartAsset calculated the amount of money a specific person would pay in income, sales, property and fuel taxes in each county in the country and ranked the lowest to highest tax burden.

To better compare income tax burdens across counties, we used the national median household income. We then applied relevant deductions and exemptions before calculating federal, state and local income taxes.

In order to determine sales tax burden we estimated that 35% of take-home (after-tax) pay is spent on taxable goods. We multiplied the average sales tax rate for a county by the household income less income tax. This product is then multiplied by 35% to estimate the sales tax paid.

For property taxes, we compared the median property taxes paid in each county.

For fuel taxes, we first distributed statewide vehicle miles traveled down to the county level using the number of vehicles in each county. We then calculated the total number of licensed drivers within each county. The countywide miles were then distributed amongst the licensed drivers in the county, which gave us the miles driven per licensed driver. Using the nationwide average fuel economy, we calculated the average gallons of gas used per driver in each county and multiplied that by the fuel tax.

We then added the dollar amount for income, sales, property and fuel taxes to calculate a total tax burden. Finally, we created the Tax Burden Index in order to show how each county in the country compares to the county with the lowest tax burden (that is the county with a Tax Burden Index of 100).
