When Are Washington DC Property Taxes Due? 2026 Dates, Rates & Exemptions

If you own property in Washington DC, knowing your tax due dates can save you hundreds in late penalties and stress. Washington DC property taxes are due twice yearly—March 31 and September 15—on a semi-annual schedule, with an effective tax rate of 0.56% that applies to most residential homeowners.

When Are Washington DC Property Taxes Due?

Washington DC property taxes follow a semi-annual payment schedule, not a single annual deadline like many other states. Your two payment dates are:

Payment Schedule	Due Date	Notes
First installment	March 31	Confirm with county treasurer
Second installment	September 15	Confirm with county treasurer

Missing either deadline can trigger late fees and tax liens. The District's tax year runs from January 1 to December 31, and assessments typically reflect property values as of the previous July.

Washington DC Property Tax Rates

Washington DC has an effective property tax rate of 0.56%, which is moderate compared to national averages. This means a homeowner with a $650,000 property—the current average home price in DC—would owe approximately $3,640 annually in property taxes, or about $1,820 per semi-annual payment.

The 0.56% rate applies to most residential properties, though specific rates can vary slightly depending on property classification and recent assessment updates. The District regularly reassesses properties, so your individual rate may differ based on your home's assessed value.

Washington DC Property Tax Exemptions

Washington DC offers several exemptions and deductions to reduce your tax burden. The most significant is the homestead deduction, which provides up to $84,000 in deductible value (2026—verify with your assessor).

To qualify for the homestead exemption, you must occupy the property as your primary residence and file a claim with the DC Office of the Assessor. Other exemptions include:

• Senior and disabled homeowner credits for eligible residents over 65 or with disabilities
• Religious organization exemptions for qualifying nonprofit properties
• Government property exemptions for federal, state, and local government buildings

Eligibility requirements and deduction amounts change annually, so contact the DC Office of the Assessor or visit their website to confirm current limits and file on time.

How to Pay Washington DC Property Taxes

You can pay your Washington DC property taxes directly to the DC Office of the Assessor or the DC Department of Finance and Revenue. Payment options include:

• Online: through the DC government's official payment portal
• By mail: send checks to the DC Department of Finance and Revenue
• In person: visit the office at 1101 4th Street SW, Washington, DC 20024
• Phone: call to arrange payment over the phone during business hours

Many homeowners with mortgages don't pay property taxes directly—their lender handles this through an escrow account as part of their monthly PITI (principal, interest, taxes, insurance) payment.

If you're unsure whether your taxes are included in your mortgage escrow, review your loan documents or contact your mortgage servicer.

What Happens If You Miss the Deadline?

Late property tax payments in Washington DC trigger significant penalties and potential legal consequences. The District typically charges 1%–2% in late fees per month on unpaid balances. If you miss a deadline, expect:

• First 30 days late: 1% monthly penalty begins accruing
• 60+ days late: penalty may increase; interest compounds
• Extended delinquency: DC can file a tax lien against your property, affecting your credit and ability to refinance or sell

A tax lien gives the District a legal claim on your home's equity. If unpaid taxes remain outstanding long enough, the property could potentially be sold at a tax sale. The best protection is to set calendar reminders for March 31 and September 15 and pay on time.

If you struggle to pay the full amount by the deadline, contact the DC Department of Finance and Revenue immediately to discuss payment plans or hardship options.

Property Taxes and Your Mortgage Payment

If you financed your DC home with a mortgage, your property taxes are likely bundled into your monthly payment through an escrow account. Your lender collects a portion each month and pays your taxes on your behalf when they're due.

Understanding your escrow breakdown helps you budget accurately. Use our free mortgage calculator for Washington DC to estimate your total monthly payment, including taxes and insurance. If your property value increases significantly, your escrow payment may rise at your loan's annual review.

First-time homebuyers in DC should know about the DCHFA/DHCD Home Purchase Assistance Program (HPAP), which offers down payment assistance up to $202,000 and can reduce your overall borrowing costs. Learn more about property tax exemptions and how they impact your long-term affordability.

Frequently Asked Questions

Q: Can I pay my Washington DC property taxes in one lump sum instead of two installments?
A: The District's semi-annual system is mandated, so you must pay twice yearly—March 31 and September 15. However, you may contact the DC Department of Finance and Revenue to discuss alternative payment arrangements if you face hardship. Paying early (before the deadline) is always allowed and recommended.

Q: What is the homestead exemption cap in Washington DC, and how do I apply?
A: The homestead deduction is up to $84,000 in assessed value (2026—verify current limits with the assessor). You must own and occupy the property as your primary residence. File a claim with the DC Office of the Assessor; deadlines and required documents are posted on their website annually. Missing the filing deadline may forfeit that year's exemption.

Q: Are Washington DC property taxes paid separately from my mortgage, or included in escrow?
A: If you have a mortgage, your lender almost certainly collects property taxes through an escrow account and pays them on your behalf. Check your loan papers or mortgage statement to confirm. Self-employed or all-cash buyers pay taxes directly to the District on the semi-annual schedule. See when property taxes are due for more details on payment methods.

Q: What should I do if I can't pay by the March 31 or September 15 deadline?
A: Contact the DC Department of Finance and Revenue immediately—do not ignore the bill. Late fees begin at 1%–2% per month, and a tax lien can be filed after extended delinquency, harming your credit and ability to refinance. The District may offer a payment plan or hardship deferral if you communicate early.
