Delaware personal income tax is a crucial part of doing business in this state as a non-resident. In this article, let BBCIncorp guide you through the process of filing your personal income tax.

Delaware personal income tax cover

Please be noted that this guide is devoted to non-resident personal income tax at the state level only. For the federal level, please consult an expert.

1. Who is subjected to personal income tax in Delaware?

You are only subjected to personal income tax in Delaware if you have income from sources within the state.

Non-residents. If you have any gross income from sources inside the state during the tax year, then it is compulsory for you to file a tax return.

Note: If you don’t have any income that is generated inside of Delaware and your spouse files a married separate return, then you do not have to file a Delaware tax return.

Part-year residents. You are obligated to file the tax return if:

  • While being a resident of Delaware, you have income that is generated within the state, or
  • As a non-resident, you had income from Delaware sources.

Note: To part-year residents, you can choose whether non-resident form or resident form to file. Therefore, opt for the one that brings more benefits.

Now, the important question arises: which one is more beneficial?

Let’s take a quick example to best illustrate this situation:

Vivian is a part-year resident in Delaware. She has streams of income from Delaware during her period of non-residency of the tax year. In this case, filing Form 200-01 R will bring her more benefits.

However, if during her period of non-residency, she earns her income from other states or even outside of the US, filing Form 200-02 NR will be more beneficial.

2. What form to file and when to file?

To non-residents, you need to file the 200-02 NR form to comply with the personal income tax law in Delaware.

However, as mentioned above, as a part-year resident, you can choose between 200-01 R or 200-02 NR form to file, whichever is more advantageous to you.

The due date for filing your individual income tax return is on or before April 30th each year. You can extend the time of filing by submitting Form 200EX prior to the due date.

3. What is the process for filing your personal income tax in Delaware?

Step 1: Complete the federal income tax and other states’ taxes

In order to prepare to file your personal income tax in Delaware, you have to finish your federal tax return as well as that of other states. This is a crucial step to prepare for filing your individual income tax in Delaware.

Step 2: File the top boxes with the most essential information

File your names and address then mark the corresponding boxes.

You are eligible to file as a single taxpayer if on December 31st of the last year. In this case, please use Filing status 1.

Filing status 2 and 3 are for married taxpayers. You can file joint or separate returns. However, if only one of you works in Delaware or both your gross income in Delaware exceeds $9,400, you should opt for separate returns as it brings more benefits.

Lastly, if you pay taxes as the head of household, choose Filing status 5.

Step 3: Proceed to fill the back of the form

After finishing the front, turn the form over and start filing the back of it. Here is a quick instruction of how to file it:

Column 1 – Your federal tax
From Line 1 to Line 17 of this Column 1 should match each line of your Federal Form 1040 and 1040 schedules (except for Filing status 3).

Column 2 – Delaware Source Income and/or Loss
List out all streams of income, gain, loss, or adjustment that are generated inside of Delaware. To part-year residents, don’t forget to include all your income from any other sources besides Delaware.

Step 4 – Finish your filing with the attached documents

After filling in all the necessary information, don’t forget to attach the corresponding documents to your Delaware tax return. Please read the next part to get insights into what documents should be included.

Step 5 – Send your Delaware income tax return

The last step to finalize your tax return is to sign and date your report. Then send it to the addresses below.

  • Submitting with the payment or balance due: State of Delaware, Division of Revenue, P.O. Box 508, Wilmington, DE 19899-508
  • Submitting with the refund due: State of Delaware, Division of Revenue, P.O. Box 8710, Wilmington, DE 19899-8710
  • Submitting the tax return alone: State of Delaware, Division of Revenue, P.O. Box 8711, Wilmington, DE 19899-8711

Please keep in mind that your income tax return is not considered complete if it is not signed and dated. Plus, it is advisable to enclose your phone number to the tax return.

4. What documents to include with your Delaware income tax return?

The following documents are necessary to attach with your Delaware income tax return:

  • DE Schedules I and III, if completed.
  • W-2 Form(s) issued by your employer and all 1099R Forms to receive credit for Delaware tax withheld.
  • A copy of your Federal 1040 Page 1 and 2 and all 1040 schedules (1, 2, 3, etc.).
  • A copy of all federal schedules you are required to file with your federal return (for example, Schedule C, D, E, etc.).
  • Delaware Schedule A (PIT-NSA), if itemizing deductions.
  • A signed copy of other state’s income tax return(s), if you claim credit for taxes paid to another state. Note: Don’t use the amount from your W-2 form(s).
  • A copy of Form 1100S, Schedule A-1, if you take a credit for taxes paid by an S corporation.
  • A copy of Form DE2210, pages 1 and 2, if you completed Part 3 of the DE2210 or if the calculated estimated tax penalty is greater than zero.
  • A copy of Form 700, Delaware Income Tax Credit Schedule, and Form 1801AC and/or Form 2001AC, if applicable.
  • A copy of Delaware Schedule W Apportionment Worksheet, if applicable. You must include pages 1 and 2.
  • A copy of Form 5403, Real Estate Tax Return, if you declared and paid estimated taxes on the sale of real estate owned in Delaware.

5. What is the possibility to extend the time of filing?

Though there is no way you can extend the time of the payment of tax, the extension for the time of filing is possible.

You can extend the time of filing by filing the Application for Automatic Extension (Form 200EX) prior to the due date of your income tax return.

Above are the five most crucial questions that can help you have a good look at the Delaware personal income tax: who has to file and how to file. If you wish to know more about Delaware taxes, it is advisable to speak to experts.
