Filing a tax return can be overwhelming, especially when dealing with prior tax years. If you lived or did business in Washington, DC, during 2015, understanding how to file the District of Columbia tax return correctly is essential for staying compliant and possibly reclaiming money owed to you. This guide is designed to walk you through the whole process, step by step.
Whether you're an individual filing your taxes for the first time, a small business owner catching up on past filings, or someone simply looking to check if you still qualify for a refund, this article will help you confidently navigate DC’s 2015 tax rules. It shows which forms to use, how to fill them out, where to send them, and how to avoid errors that could delay your return.
You don’t need to be a tax expert or use complex tax software to understand the process. With the proper guidance and a bit of effort, filing your 2015 DC tax return is manageable. Even if it’s been several years, you may still be eligible to file and receive a refund if you act in time.
Whether you must file a 2015 District of Columbia tax return depends on several factors, including residency status, income level, and federal filing obligations. This section will walk you through each scenario to help you determine if filing is necessary.
You’re considered a District of Columbia resident for tax purposes in 2015 if any of the following applied:
This 183-day rule is significant for people with temporary or dual residences. If you have kept a home in DC and spent more than half the year there, the Office of Tax and Revenue may consider you a resident, even if your driver’s license or voter registration is from another state.
If you were a DC resident and required to file a federal income tax return (Form 1040, 1040A, or 1040EZ) in 2015, you likely needed to file a DC tax return. The DC return works with your federal return, using much of the same income information to determine your DC tax liability.
If you weren't required to file a federal return, DC usually doesn’t need one either—though there are some exceptions if you had tax withheld or qualify for certain local credits.
You may not need to file a 2015 DC tax return if:
These exemptions apply to federal government employees and congressional staff under special residency laws. DC taxes function similarly to other state income taxes for most working residents.
If you moved in or out of DC during 2015, your part-year residency may still trigger a filing requirement. You’ll likely need to report only the income earned while living in DC. Military service members with DC as their home of record must file, even if stationed elsewhere during the year.
Deadlines and Tax Changes for 2015
When preparing to file your 2015 DC tax return, knowing the correct deadlines and changes for that year can help you avoid penalties and file with confidence. While 2015 may seem distant, the District of Columbia has strict guidelines for filing past returns, including cutoff dates for refund eligibility.
The official filing deadline for the 2015 tax year was April 18, 2016. This adjusted date took Emancipation Day into account, which fell on Tuesday, April 15, pushing the federal and DC tax due dates to the following Monday.
Here are the original deadlines and available extensions for different return types:
If you didn’t file by these deadlines and are due a refund, you generally have three years from the original due date to submit your return. Thereafter, you may lose your right to claim any refund.
Several vital updates were introduced for 2015:
These changes impacted how much individuals owed or received back, especially for those using older tax software or relying on previous-year calculations.
Before you begin the filing process, gathering the proper tax forms based on your filing status and income type is essential. DC uses different forms for individuals, sole proprietors, and businesses, so using the correct one will help prevent delays and avoid rejections.
Form D-40EZ
Best for:
You cannot use this form if you:
This form is simpler to complete, making it a helpful option for those filing independently for the first time.
Form D-40
Best for:
This standard individual income tax form offers more flexibility for reporting credits, deductions, and complex income.

Used by:
This form is strictly for refund purposes if you weren’t required to file a regular DC return.

2. Form D-20 (Corporate Franchise Return)
3. Form D-65 (Partnership Return)
If you need more time to file (but not to pay), use:
Always use DC-specific forms for extensions. Submitting a federal extension form will not apply to your DC taxes.
Filing your District of Columbia tax return for 2015 requires accuracy, attention to detail, and the proper documents. Whether you're filling out the individual Form D-40 or the business Form D-30, following a structured process will reduce the chance of errors and help you file confidently.
Before starting, collect the following:
Everything on hand will make the preparation process smoother and save time during data entry.
Use capital letters and black ink when completing your form by hand. Start by entering:
For 2015, DC added a new filing status: qualifying widow(er) with a dependent child.
Transfer income information directly from your federal return:
Avoid recalculating federal totals. Simply copy the appropriate values onto your DC return.
Your exemption amount for 2015 is $1,775 per person. Multiply this by the number of exemptions you're claiming.
If your adjusted gross income (AGI) exceeds $150,000, your exemption will be reduced by 2% for every $2,500 over that threshold. No exemption is allowed if AGI exceeds $275,000.
Choose between:
Use the 2015 DC tax rate schedule or the tax tables in the instruction booklet to compute your tax liability. Apply the correct rate based on your DC taxable income after deductions and exemptions.
Some common credits include:
You may only claim one EITC or Low Income Credit—not both.
Add up the following:
This total will determine whether you’re owed a refund or must pay additional tax.
You can receive your refund by:
Be sure your routing and account numbers are accurate if you choose a direct deposit.
Carefully sign and date the return. If filing jointly, both spouses or domestic partners must sign. Review all calculations and attachments before submission.
Avoiding these issues will help ensure your return is accepted and processed quickly.
Filing your District of Columbia tax return for 2015 can be done in two main ways: electronically or by paper. Each option has its own process, benefits, and tools. Choosing the correct method depends on your preferences, available resources, and how comfortable you are using tax software or online platforms.
Many individuals and small businesses prefer electronic filing. It’s generally quicker and more secure and helps reduce errors, thanks to built-in validation checks in most tax preparation software.
DC residents had access to several tax software platforms that support e-filing. These include well-known providers like Intuit (TurboTax), H&R Block, and other companies approved by the IRS. Many of these platforms work on any internet-connected device, such as a laptop or tablet, and offer guided instructions to simplify the process.
If you’re filing a past return for 2015, be aware that not all software will support prior-year filings directly. You may need to download older forms or use free fillable options if your software doesn’t offer full access.
The DCfreefile program allowed eligible taxpayers to file their DC return online at no cost. Even if you're filing late, you may still be able to access free fillable forms through DC's taxpayer portal, provided you have the necessary documents from 2015.
These tools are invaluable for first-time filers, offering guidance at each step to avoid mistakes and maximize efficiency.
If you prefer paper filing, be sure to:
Include only one return per envelope, and use the correct address based on whether you're submitting a payment. While paper filing can be more time-consuming and involve more effort, some individuals still find it reassuring for recordkeeping or personal control.
If your 2015 DC tax return shows that you owe money, paying promptly is essential—even if you're filing late. Paying as soon as possible helps avoid penalties and interest accumulating over time. The District of Columbia offers multiple ways to submit payments, with traditional and digital options available.
You can choose from several secure methods:
Submitting your payment on time is a smart way to avoid unnecessary stress or hassle. It also shows you're taking responsibility for your tax obligations with minimal effort.
Once you've filed your 2015 District of Columbia tax return, you may be expecting a refund or checking whether you still have a balance due. DC offers a few ways to monitor your account, but timelines may vary depending on how you filed and the accuracy of your return.
If you're owed money, you may have chosen one of these three methods when you filed:
To track your refund:
Electronic returns are usually processed more quickly than paper ones. However, it may take longer if your return had errors, missing documentation, or triggered a manual review.
The District has recently added extra identity verification steps, which, while occasionally slower, offer reassuring protection against refund fraud. These safeguards help build trust with taxpayers and ensure refunds reach the right people.
If you still owe taxes after filing, visit the same portal to check your balance and make secure payments.
Before sending off your 2015 DC tax return, take a moment to review this checklist. These last steps can help you prepare your documents correctly and avoid the hassle of corrections or delays.
Whether filing on paper or electronically, this list will help ensure you’ve covered the essentials.
These steps may seem small, but they can make a big difference. A careful review helps determine whether anything is missing and reduces the effort required for corrections. Following this checklist provides a helpful structure for a smoother filing experience.
If you’re new to tax filing, it’s best to start by reviewing your 2015 federal return and gathering DC-specific forms. DC offers helpful resources, and many users prefer using tax preparation software with step-by-step guidance. These tools simplify the process for beginners, reduce errors, and make tracking what you owe or might receive as a refund easier.
Many people have successfully filed their taxes, even in past years. If your 2015 return is simple and you have records, you can download the necessary forms and instructions from DC’s tax site. Just be sure to follow the checklist carefully. However, having expert help might save time and reduce filing errors for more complex returns.
While most modern tax preparation software focuses on current-year returns, some platforms still support prior years, including 2015. You may need to download the forms manually or use fillable PDFs. Still, tax software can guide your entries, offer expert help, and help identify common credits and deductions. It’s especially valuable for those filing late and aiming for accuracy.
Both options can work. Tax experts are helpful if you have multiple income sources, have moved states, or own a business. They can also assist if you’re unsure which forms or deductions apply. On the other hand, using software with built-in expert help is often more affordable and convenient for standard returns. Choose what makes you feel most confident.
To get the max refund, make sure you report all withholdings from W-2s or 1099s and claim every eligible credit—such as the DC Earned Income Tax Credit or property tax relief. Review the instructions carefully and consider using tax filing tools or consulting an expert to check for missed opportunities. Even small details can make a big difference in what you receive.
