Every person who has lived in the District for part or all of 2019, has earned income, or intends to claim a refund must follow the rules set by the DC tax department.

By the end of this guide, you will have the information and resources needed to meet your obligations and protect your financial interests.
The District of Columbia income tax system operates under rules set by the DC tax department, with rates and requirements that differ from federal tax laws. Every taxpayer who earned income in 2019 and meets the filing criteria must submit a DC income tax return, regardless of whether they also filed a federal return. The process involves using the correct forms, calculating your income accurately, applying deductions, and determining the tax credits you can claim. Filing ensures that any payment due is made promptly and any refund owed is issued promptly.
While the Internal Revenue Service processes federal returns, DC returns are handled directly by the local tax department. Some deductions and income credits available at the federal level may not apply in DC, and the reverse is also true. Taxpayers should review DC-specific rules before filing to avoid errors. For example, certain income tax credits, such as the Earned Income Tax Credit, have different eligibility requirements in DC compared to federal guidelines. In some cases, amended returns may be necessary if adjustments are made to your federal filing.
For 2019, the main form for individuals is Form D-40, which replaced the retired D-40EZ. Additional schedules may be required depending on deductions, credits, and income sources. Forms must be submitted by the filing deadline, either electronically using approved tax software or by mail to the correct address. Taxpayers can visit the District of Columbia Office of Tax and Revenue for official instructions, forms, and payment options. Reliable financial institutions should be used for direct deposits or electronic payments to ensure that accounts are credited accurately. Keeping copies of all submitted documents is essential in case of a notice or review.
Individuals who meet specific residency and income criteria must file a 2019 District of Columbia income tax return. The DC tax department sets these rules to ensure all qualifying taxpayers report their earnings, pay the tax owed, and claim eligible income tax credits. Filing also ensures refunds are issued to those entitled to them and helps avoid penalties from missed deadlines or incomplete forms.
Meeting these conditions requires completing the correct forms, using approved tax software or paper filing, and sending them to the correct mailing address. Reviewing documentation, verifying account details, and ensuring clear records ensures the filing process is accurate and efficient.
For the 2019 tax year, the DC tax department eliminated the simplified Form D-40EZ. All taxpayers, regardless of income or filing complexity, must use Form D-40. This change affected many individuals who previously filed shorter forms and meant additional schedules might be necessary for deductions, income credits, or other reporting requirements. Taxpayers had to review their forms carefully before submission to ensure accuracy and avoid processing delays.
Starting in 2019, District of Columbia residents had to maintain qualifying health insurance coverage, qualify for an exemption, or pay a penalty. This rule applied to every household member, including dependents, and was reported on Schedule HSR. The penalty amount was calculated based on household income or a flat fee, whichever was higher, and added to the total amount owed. Individuals without coverage for part or all of the year needed to review exemption categories and determine if they qualified for relief from this payment. More details on exemptions, penalties, and related policy impacts can be found at the DC Policy Center.
The standard deduction amounts increased for all filing statuses in 2019, giving taxpayers higher reductions in taxable income. Changes were also made to the property tax credit, raising maximum amounts and expanding eligibility thresholds. The Early Learning Tax Credit was also renamed the Keep Child Care Affordable Tax Credit, reflecting updated income limitations and credit amounts. These adjustments meant taxpayers could claim more benefits, but only if they completed the necessary forms and met all qualifications. Reviewing updated instructions helped ensure no credit or deduction was overlooked during the filing process.
For the 2019 tax year, the standard filing deadline for District of Columbia income tax returns was April 15, 2020. However, in response to the COVID-19 public health emergency, the DC tax department extended the due date to July 15, 2020. This change provided taxpayers additional time to gather documents, calculate deductions, and claim applicable income tax credits without incurring late filing penalties. Taxpayers who owed money were still encouraged to make payments as early as possible to avoid accumulating interest charges. This extension aligned with changes to the federal tax calendar, helping individuals and households manage both filing requirements during an uncertain period.
Taxpayers who need more time beyond the July deadline can request a formal extension by submitting Form FR-127. This filing allowed an additional six months to send in the required forms, with the extended due date falling in October 2020. It is important to note that extending the filing does not extend the time to pay tax owed. Payments must be made by the original deadline to prevent interest and penalties from accruing. Individuals submitting an extension request were advised to review their account details, confirm payment amounts, and mail or submit the form using approved electronic methods. Clear communication with the tax department and timely submission of required documents helped ensure the extension process proceeded smoothly.
Filing your 2019 District of Columbia income tax return requires careful preparation and attention to detail. The process includes gathering the correct forms, entering accurate information, applying deductions, and claiming eligible income tax credits. Whether you file electronically or by mail, the DC tax department requires all taxpayers to follow established procedures to ensure accurate processing.
Filing electronically through approved tax software offers faster processing and fewer errors. This option also allows taxpayers to review entries and correct mistakes before submission. Paper filers must use black ink, attach all required documents, and mail the return to the correct address for returns with or without payments.
By following these steps, taxpayers can complete the filing process efficiently, avoid delays, and ensure they receive any refunds or credits they are entitled to claim.
Missing Signatures
One of the most common errors is forgetting to sign the tax return. Both spouses must sign if filing jointly. An unsigned return is considered incomplete and will not be processed by the tax department, delaying any refund or notice of balance due.
Incorrect Mailing Address
Using the wrong mailing address when sending a paper return can cause significant delays. DC has separate addresses for returns with payments and those expecting refunds. Always review the current instructions before mailing your forms.
Failing to Claim Available Income Tax Credits
Taxpayers often miss credits they are entitled to, such as the Earned Income Tax Credit or homeowner property tax credits. These credits can reduce the amount you owe or increase your refund. Ensure that all qualifying income credits are calculated and entered accurately.
Math and Calculation Errors
Errors in calculating taxable income, deductions, or credits can change the amount owed or refunded. Using approved tax software or having your return reviewed can help avoid these mistakes.
Ignoring Tax Department Notices
If the tax department sends a notice or letter, respond promptly. Ignoring correspondence can result in penalties, additional interest, or the loss of an opportunity to resolve an issue quickly.
Omitting Required Forms or Schedules
Missing schedules or attachments, such as Schedule HSR for health coverage reporting, can result in processing delays or the rejection of your return.
Your 2019 District of Columbia income tax return can be filed electronically or by mailing a paper return. Choosing the correct method depends on speed, convenience, and recordkeeping preference. The DC tax department encourages taxpayers to use electronic filing whenever possible to reduce errors and receive refunds faster.
Filing online allows taxpayers to track submission status, receive confirmation, and avoid mailing delays. It also ensures the secure transfer of sensitive account and payment information to the tax department.
Paper filing requires careful completion of all forms, attachment of W-2s and other documentation, and mailing in time to meet the deadline. Taxpayers should verify that the correct mailing address is used to prevent processing delays.
Selecting a filing and payment method that meets your needs helps ensure the process is completed accurately and on time.
Taxpayers can track the status of their 2019 District of Columbia income tax refund by visiting the tax department’s secure online portal. To use this tool, you will need your Social Security number, the exact refund amount, and the tax year. The system updates whether your return has been received, is under review, or has been approved for payment.
E-filed returns are typically processed within 7–10 business days, while paper returns may take four to six weeks. Returns requiring additional review, such as those with amended returns or income credit claims, can take longer. The processing timeline can also be affected by missing forms, calculation errors, or mismatches with federal records.
The online system can confirm payment posting dates and outstanding balances if you owe money instead of receiving a refund. Any notice or letter from the tax department should be reviewed carefully, as it may request additional documentation or clarification. Prompt action can help prevent further interest or penalties and ensure your account remains in good standing.
Contact the DC tax department by phone, email, or in person. Corporations must file Form D-20, while unincorporated businesses, including sole proprietors and partnerships, must file Form D-30 if their gross receipts exceed $12,000. Even if a company has no tax liability, filing is necessary when income thresholds are met. Entities organized outside DC but conducting business in the District may also be required to file, depending on their activity level.
The corporate and unincorporated business tax rate 2019 was 8.25 percent of taxable income. A minimum tax is applied to businesses based on gross receipts: $250 for those with receipts under $1 million, and $1,000 for those above this amount. Certain small retailers could qualify for the Small Retailer Property Tax Relief Credit, which refunded a portion of rent or property tax paid. The filing deadline for business returns matched the individual tax filing date of July 15, 2020, for calendar-year filers, reflecting the COVID-19 extension. Businesses with fiscal years were required to file by the 15th day of the fourth month following the end of their fiscal year. Accurate account records, verified deductions, and reviewed forms helped ensure compliance and prevent delays in processing or receipt of refunds.
The Earned Income Tax Credit (EITC) in the District of Columbia is available to qualifying taxpayers who meet income, filing status, and dependent requirements. For 2019, eligibility was based on earned income and adjusted gross income limits that varied according to household size. A person with qualifying children and some taxpayers without children could claim the credit if they met all the rules. Taxpayers must also have a valid Social Security number, file a DC income tax return, and not be claimed as a dependent on another person’s return.
DC’s EITC amount is 40 percent of the federal EITC, meaning taxpayers who qualify for the federal credit automatically qualify for the DC version, subject to income limitations. The credit is refundable, allowing taxpayers to receive money even if their tax liability is reduced to zero. This income credit can be applied directly to reduce the amount owed or increase a refund. Those who later submit amended returns may adjust their EITC claim if federal changes affect their eligibility.
An additional provision allows noncustodial parents with specific support and income requirements to claim a version of the EITC. This helps encourage consistent child support payments while providing financial relief to eligible taxpayers. Determining whether you qualify for this option requires reviewing the specific rules and ensuring all documentation is accurate before filing.
The District of Columbia offers a refundable property tax credit for homeowners and renters who meet specific income and residency requirements. For 2019, the maximum credit was $1,200, with eligibility thresholds based on adjusted gross income. Homeowners qualified if they paid property tax on their primary residence, while renters qualified if they paid rent on a taxable property. In calculating eligibility, the DC tax department considers a percentage of rent as equivalent to property tax paid. This credit can reduce the amount you owe or increase your refund.
Formerly known as the Early Learning Tax Credit, this program provides financial assistance to families with children enrolled in licensed childcare facilities in DC. For 2019, credit amounts varied based on income and the number of eligible dependents. Taxpayers claiming this credit must submit Schedule ELC and their DC income tax return. The credit is refundable, allowing families to receive money without tax liability, which can be especially valuable for households managing tight budgets.
Other income credits include incentives for qualified high-technology company investments and specific environmental programs. Each credit has its own eligibility requirements, forms, and limitations. Taxpayers should review all available credits before filing to ensure they do not miss opportunities to reduce their tax liability. The DC tax department’s official resources offer guidance on credit calculations, supporting documentation, and claim procedures. Keeping detailed records and submitting accurate forms helps ensure that all qualifying credits are applied correctly, which can improve the overall financial outcome of your return.
Some taxpayers who lived in the District of Columbia for part of 2019 may also have filing obligations in another state, such as California. You may need to file returns in each location if you earned income in both DC and another jurisdiction. This can involve determining which income is taxable in each jurisdiction, applying credits to avoid double taxation, and ensuring compliance with DC and out-of-state rules. Accurate records and reviewed forms are critical for meeting all filing requirements.
In certain situations, a person may need to visit the DC tax department in person to resolve account issues, submit documentation, or clarify notices. This can be necessary if online or mail options do not address a specific problem, or if time-sensitive matters require direct resolution. Bringing all relevant documents, identification, and copies of correspondence ensures the process is handled efficiently. Taxpayers can also contact the department in advance to confirm hours, required materials, and the best methods for addressing their concerns.
Verify Personal and Tax Information
Ensure your name, Social Security number, filing status, and dependent details are accurate. Even a minor error can delay processing or lead to notices from the tax department.
Confirm All Forms and Schedules Are Included
Attach all required forms, such as Form D-40, W-2s, 1099s, and schedules for deductions or credits. Missing documentation can result in a rejected return or a request for additional information.
Review Deductions and Credits
Double-check that all eligible income tax credits and deductions have been claimed, including property tax credits and the Earned Income Tax Credit. This helps maximize your refund or reduce the amount you owe.
Choose and Verify Payment or Refund Method
If you owe tax, confirm the payment amount and method. For refunds, verify account information for direct deposit to ensure funds are sent to the correct financial institution.
Retain Copies of All Documents
Keep a complete copy of your return, supporting records, and correspondence for at least three years. This is essential if you need to respond to a notice, file amended returns, or verify prior filings.
If you miss the deadline, the DC tax department may assess penalties and interest on any amount you owe. File as soon as possible to reduce these charges. If you are due a refund, you must still file within three years of the original deadline to claim it.
To file an amended return, use Form D-40, check the “Amended Return” box, and include all required schedules. Explain the changes in the space provided. If the change results from a federal adjustment, submit your amended DC return within 90 days of receiving the federal notice.
Yes, renters may qualify for the property tax credit. DC treats 20 percent of annual rent as equivalent to property tax paid. You must meet income limits and residency requirements for 2019 to claim the credit. Submit Schedule H with your return to apply for this benefit.
You may qualify for the DC Earned Income Tax Credit if you meet income limits, have a valid Social Security number, and file a DC tax return. The credit equals 40 percent of the federal EITC. Both taxpayers with and without qualifying children may be eligible.
Review the bill carefully to confirm the amount owed and the reason for the charge. If you agree, pay by the date shown to avoid further interest. If you disagree, immediately contact the DC tax department to request clarification or file an appeal with supporting documentation.
Yes, as long as you file within three years of the original deadline. To receive a refund, your return must be filed for the 2019 tax year by July 15, 2023. After this date, the refund amount will be forfeited under DC law.
You can contact the DC tax department by phone, email, or in person. Visit their website for contact information, hours, and service options. If visiting in person, bring all necessary documents, identification, and copies of prior correspondence for faster service.
