State Income Tax in Delaware

Delaware imposes a progressive income tax, which means that the tax rate increases with higher income levels. The state has six tax brackets that range from 0% to 6.6%. The state's tax schedule mandates that all individuals earning more than $2,000 annually from Delaware sources must file a tax return. Those earning less than $2,000 are exempt from filing returns but may need to file if federal income tax is withheld from their earnings.

Delaware Non-Resident Income Tax Returns

Individuals who live outside Delaware but earn income within the state's borders must file a non-resident income tax return. Nonresidents earning income from Delaware sources have to file their tax returns using Form 200-02. This form is available online and can be downloaded and printed.

Filing Methods and Deadlines

Delaware's tax forms must be filed by April 30th of each year. It is important to note that the state has extended the filing deadline temporarily due to the ongoing COVID-19 pandemic. Delaware residents can file their returns electronically or on paper. There are several options for e-filing, which include free online tax preparation software and paid tax preparation services.

For those who prefer paper returns, all necessary forms are available on the Delaware Tax Center website. Ensure that the correct form is filled out and all required information is provided in a timely manner. Filing erroneous or incomplete returns may lead to penalties.

Credits and Deductions

Delaware offers numerous tax credits and deductions for taxpayers. These credits and deductions lower the taxable income, resulting in a lower tax liability. Some available credits and deductions include:

1. Personal Exemption

Delaware taxpayers are entitled to a personal exemption of $110 for the tax year 2021, which reduces the amount of taxable income.

2. Standard Deduction

Single filers can claim a standard deduction of $1,250 while married couples can claim $2,500.

3. Itemized Deductions

Taxpayers who opt not to utilize the standard deduction can itemize deductions to reduce their taxable income. Common itemized deductions include medical expenses, charitable contributions, and state and local taxes paid.

4. Child Care Credit

Delaware provides a child care credit to taxpayers who have paid expenses related to child care. The credit is capped at $150 per child, with a limit of $300.

5. Earned Income Tax Credit

The Earned Income Tax Credit (EITC) is available to eligible taxpayers with low to moderate incomes. Delaware's EITC is 20% of the federal credit, or 3.9% of the value of earned income, whichever is higher.
