How to Pay Your DC Property Tax and Understand What You Owe

Where and How to Pay DC Property Tax

DC property tax payments go to the Office of the Chief Financial Officer (OCFO), which is the only place that accepts them. You can pay online through the DC government website, by mail, in person at their office, or by phone. Online payment is the fastest route — you can pay immediately and get a confirmation number the same day.

To pay online, you will need your property's square number (a unique identifier for DC real estate) or your account number, which appears on your tax bill. The DC OCFO website has a payment portal where you enter these details, choose your payment method (debit card, credit card, or bank account), and submit. If you pay by mail, send a check or money order to the DC OCFO at the address listed on your bill. Payments by mail typically take 7 to 10 business days to post to your account.

Key Takeaways

• DC property tax bills are mailed twice a year — one bill covers July through December, and another covers January through June.
• You can pay online, by mail, by phone, or in person at the OCFO office, and online payment posts to your account the same day.
• If you miss a payment deadline, a penalty of 10 percent is added to the unpaid amount, plus interest that accrues daily.
• Homeowners over 65, disabled homeowners, and those with low incomes may may have access to for tax relief programs that reduce what you owe.
• Your property tax bill includes both the city tax and the water and sewer charges, which are billed together.

When DC Property Tax Is Due

DC property tax bills are issued twice per year. The first bill covers the period from July 1 through December 31, and the second covers January 1 through June 30. Each bill has a due date printed on it — typically 30 days after the bill is mailed. If you do not pay by the due date, a 10 percent penalty is added to the unpaid amount, and interest begins to accrue at a rate set by DC law (this rate changes annually).

The interest compounds daily, which means the longer you wait, the more you owe beyond the original tax. If your bill is not paid within a certain period, the OCFO can place a lien on your property, which means the city has a legal claim against it. This lien can affect your ability to sell or refinance the property until the debt is paid.

Understanding Your Property Tax Bill

Your DC property tax bill shows the assessed value of your property, the tax rate applied to that value, and the total amount due. The assessed value is determined by the DC Office of the Assessor, which estimates what your property is worth based on recent sales of similar properties in your neighborhood. This assessment happens every three years, though you can request a reassessment if you believe the value is wrong.

Your bill also includes water and sewer charges, which are billed together with property tax. These charges are based on your water meter reading and are calculated separately from the property tax itself. The bill will break down each charge so you can see what portion is property tax and what portion is water and sewer.

Tax Relief and Exemption Programs

DC offers several programs that can reduce or eliminate your property tax bill. The Homestead Property Tax Deduction is available to owner-occupants and reduces the assessed value of your home by up to $75,000, which lowers your tax bill. To use this deduction, you must own and live in the property as your primary residence and file a form with the OCFO.

The Senior Citizen Real Property Tax Relief Program provides reduced taxes for homeowners age 65 and older with household incomes below a certain threshold (the income limit changes yearly). The Disabled Individual Real Property Tax Relief Program offers similar relief for homeowners with disabilities. Both programs require you to file an application and provide proof of age, disability status, or income. The Low-Income Homeowner Property Tax Relief Program helps homeowners with incomes below 80 percent of the area median income. Each program has different income limits and benefit amounts, so contact the OCFO to learn which one fits your situation.

What Happens If You Cannot Pay on Time

If you cannot pay your full bill by the due date, contact the OCFO before the deadline. The office can sometimes arrange a payment plan that spreads your bill across several months, though you will still owe the 10 percent penalty and interest on the unpaid balance. Payment plans are not automatic — you must request one and the OCFO must approve it based on your circumstances.

If your property tax debt becomes very large and remains unpaid for an extended period, DC can sell your property at a tax sale to recover the money owed. This is a last resort and typically happens only after years of non-payment and multiple notices, but it is a real consequence. If you are struggling with your bill, reaching out early gives you more options than waiting until a lien or sale process begins.

How to Check Your Property Tax Account

You can look up your property tax account online through the DC OCFO website using your square number or account number. The online portal shows your current bill, payment history, and any penalties or interest owed. This is useful if you want to verify that a payment you made has posted or if you need to check how much you still owe.

If you cannot find your square number, you can search for it using your street address on the DC Assessor's website. The Assessor's site also shows the assessed value of your property and the date of your last assessment, which can help you understand how your tax bill was calculated.

Disputing Your Assessed Value

If you believe your property's assessed value is too high, you can file a Petition for Reconsideration with the DC Office of the Assessor. This petition must be filed within 45 days of the date your assessment notice was mailed. You will need to provide evidence that the assessed value is wrong — this might include recent appraisals, comparable sales in your neighborhood, or documentation of property defects that lower the value.

The Assessor's office will review your petition and either uphold the assessment, lower it, or raise it. If you disagree with their decision, you can appeal to the DC Board of Equalization and Assessment Appeals, though this process takes longer and may require you to present your case in person or through a hearing.

Frequently Asked Questions

Can I pay my DC property tax with a credit card?

Yes, the DC OCFO online payment portal accepts credit and debit cards. Be aware that the OCFO may charge a processing fee for credit card payments, so check the portal for the current fee before you submit. Paying by bank account transfer (ACH) typically has no fee.

What if I own property in DC but live out of state?

You still owe DC property tax on any real estate you own in the city, regardless of where you live. You can pay online or by mail using the same methods available to DC residents. If you have a property manager or attorney handling the property, you can authorize them to receive bills and make payments on your behalf.

Does DC property tax include homeowners insurance?

No. Your property tax bill covers only the city tax and water and sewer charges. Homeowners insurance is a separate bill that you pay directly to your insurance company. If you have a mortgage, your lender may require you to pay insurance and property tax into an escrow account, but these are still separate charges.

How often does DC reassess property values?

DC reassesses all properties every three years. You will receive a notice in the mail when your property is reassessed. If your assessed value went up significantly, you can file a Petition for Reconsideration within 45 days of the notice to challenge it.

What happens if I inherit property in DC?

You become responsible for the property tax on inherited property once the property is transferred to your name. The tax bill will continue to be based on the assessed value at the time you inherit it, unless the Assessor's office reassesses it as part of their regular cycle. Contact the OCFO to make sure the bill is sent to your address and to set up payment if needed.
