DC Property Tax Guide: Pay, Search, Due Dates & Exemptions
DC property tax is easier to handle when you start with the correct real property account instead of jumping straight to payment. A wrong Square/Suffix/Lot, old bill, mortgage escrow assumption, Homestead issue, senior or disabled relief question, vacant classification, or tax lien notice can change what you should do next.
This guide explains the important steps in plain English. Use it to understand the bill, tax rate, payment options, due dates, exemptions, appeals, and tax-sale risk, then use the official DC Office of Tax and Revenue portal only when you are ready to search, pay, file, appeal, or confirm account-specific details.
Quick Answer
To handle DC property tax safely, search the real property account through MyTax.DC.gov or OTR’s real property database, confirm the address and Square/Suffix/Lot, review the bill period, check payment status, verify any Homestead or tax-relief benefit, then pay only through an official DC payment option. Real property bills are generally paid twice a year: first half by March 31 and second half by September 15.

Before You Pay: 7 Checks That Prevent Most DC Property Tax Problems
Most payment problems happen because the owner pays too quickly. Use these checks before entering bank or card details.
How to Search DC Property Tax Records
DC real property can be searched through MyTax.DC.gov and OTR’s real property tax database. The most important identifiers are the property address and the Square/Suffix/Lot, often called SSL. Some properties may use Parcel and Lot.
- Open MyTax.DC.gov or the OTR real property tax database.
- Choose the real property search or payment option.
- Enter the property address or Square/Suffix/Lot.
- Click the property result carefully and confirm the address.
- Review billing, assessment, ownership, classification, and payment information before paying or filing.
- Open the OTR Real Property Tax Database Search page.
- Use available search options for property value, assessment roll, and parcel details.
- Compare the record with your bill, deed, mortgage statement, or closing documents.
- Use the result to decide whether the issue is billing, payment, assessment, or tax relief.
Search tips if the property does not appear
- Try the street number and street name without apartment or unit details first.
- Try the Square/Suffix/Lot from your deed, tax bill, settlement statement, or prior record.
- Check whether a suffix is blank instead of zero, or whether the property uses Parcel and Lot.
- Confirm that you are searching a real property account, not personal property tax.
- If the property has a condo unit, parking space, or abutting lot, confirm each account separately.
How to Pay DC Property Tax Online, by ACH/eCheck, Card, Check or Money Order
DC OTR allows real property and BID tax bills to be paid online through MyTax.DC.gov. Online payments before 5 p.m. Eastern are effective the same day they are authorized, and payments cannot be scheduled for a later date.
- Open MyTax.DC.gov.
- Under Real Property, choose “Make a Real Property Payment.”
- Enter the Square, Suffix and Lot, or search by property address.
- Click the property hyperlink to retrieve the account information.
- Select the tax account and payment type.
- Submit payment and keep the submission confirmation number.
| Payment Method | What to Know | Best Use |
|---|---|---|
| ACH/eCheck online | OTR lists ACH/eCheck payments on MyTax.DC.gov as free. | Good for most owners who want a direct online bank payment. |
| Credit or debit card | A 2.25% non-refundable convenience fee applies through the processor. | Useful when a card is preferred, but review the fee before paying. |
| Check or money order | Make it payable to “DC Treasurer” and include Square/Suffix/Lot or Parcel/Lot details. | Useful for mailed payments when you include the payment coupon. |
| ACH Credit | The payer sends a bank file using required EFT/NACHA instructions. | Usually used by businesses, bulk payers, or professional payment workflows. |
| Mortgage escrow | Escrow collection is not the same as posted payment. | Check posted OTR payment status before paying personally. |
Duplicate payment warning: If your lender usually pays through escrow, check MyTax.DC.gov before paying yourself. If both you and the lender pay, you may have to wait for correction or refund handling.
DC Property Tax Due Dates
DC real property tax bills are generally issued twice a year. The first-half bill covers October 1 through March 31 and is due by March 31. The second-half bill covers April 1 through September 30 and is due by September 15.
- Open the OTR due-date page or MyTax.DC.gov.
- Search your real property account.
- Confirm whether the bill is first-half, second-half, BID, delayed, or prior-year.
- Check whether a delayed bill has an adjusted due date.
- Pay before the deadline to avoid penalty and interest.
| Bill Period | General Due Date | What to Do |
|---|---|---|
| First half | March 31. | Check the February bill, confirm payment status, and verify escrow before paying. |
| Second half | September 15. | Check the August bill and confirm that credits or assessment changes are reflected. |
| Delayed bill | Adjusted by OTR when mailing is delayed. | Read the bill and OTR notice instead of assuming the normal date. |
| BID tax or other charge | May appear with real property billing or separate instructions. | Confirm the exact account and charge type before paying. |
| Prior-year or delinquent balance | Past due. | Check penalty, interest, lien sale, and redemption risk immediately. |
DC Property Tax Rates and How the Bill Is Calculated
DC property tax rates depend on property class. Residential property is generally taxed differently from commercial, vacant, and blighted property. The final bill can also be affected by Homestead, assessment cap credit, senior or disabled relief, BID tax, trash credit, late charges, and other account-specific items.
- Find the assessed value from your OTR record or bill.
- Confirm the property class.
- Divide the taxable assessed value by 100.
- Multiply by the applicable tax rate.
- Subtract eligible credits or deductions shown on the bill.
- Use the official bill as final because credits and charges can change the amount.
| Class | Current Rate Structure | What It Means |
|---|---|---|
| Class 1A | $0.85 per $100 of assessed value. | Residential real property, including multifamily, under OTR’s classification. |
| Class 1B | No more than two dwelling units: first $2.558 million at $0.85 per $100; amount above that at $1.00 per $100. | Applies to certain residential property with no more than two dwelling units. |
| Class 2 | Commercial and industrial rates vary by value tier. | Hotels, motels, commercial, and industrial property may have higher rates. |
| Class 3 | $5.00 per $100 of assessed value. | Vacant real property classification can create a much larger bill. |
| Class 4 | $10.00 per $100 of assessed value. | Blighted real property classification can be extremely costly. |
Important: If your property is classified as vacant or blighted, do not treat it like a normal residential bill. Classification questions involving Class 3 or Class 4 may require contact with the proper DC agency and official appeal steps.
DC Property Tax Exemptions, Deductions and Relief Programs
DC property tax help can come through deductions, credits, relief programs, and deferrals. The most common owner-occupied residential program is the Homestead Deduction, but seniors, disabled owners, disabled veterans, surviving spouses, low-income seniors, and certain condo or cooperative owners may need to review additional programs.
| Program | Who Should Review It | Key Official Detail |
|---|---|---|
| Homestead Deduction | Owner-occupants using the DC property as their principal residence. | For TY 2026, OTR lists a $91,950 assessed-value reduction, saving $781.58 annually. |
| Senior Citizen or Disabled Property Owner Relief | Owners age 65 or older, or disabled owners, who qualify for Homestead and meet ownership/income rules. | Qualified owners may receive a 50% property tax reduction. |
| Senior Assessment Cap Credit | Properties receiving Homestead and senior or disabled owner relief. | OTR describes an automatic credit that generally limits taxable assessed value increases to 2%. |
| Disabled Veterans’ Homestead Deduction | Qualifying veterans with total and permanent disability or 100% unemployability rating. | OTR lists a $445,000 assessed-value reduction for qualifying properties. |
| Disabled Veteran’s Spouse Homestead Deduction | Eligible surviving spouses of disabled veterans. | Effective October 1, 2025, qualifying property may receive a $445,000 assessed-value reduction. |
| Low-Income Senior Tax Deferral | Low-income seniors who want to defer property tax instead of paying immediately. | OTR lists household AGI under $50,000 and additional ownership, occupancy, and age rules. |
| Trash Credit | Certain condo, cooperative, or homeowner association owners who pay for private trash collection. | OTR lists a $136 trash credit for 2026 where conditions are met. |
- Open MyTax.DC.gov.
- Go to Real Property and choose the application option for Homestead Deduction, including Senior Citizen or Disabled Tax Relief.
- Search by address or Square/Suffix/Lot.
- Complete the application and submit it online.
- Save the submission confirmation number and confirmation email.
Eligibility reminder: If the property stops being your principal residence, ownership changes, the property is rented, or you otherwise become ineligible, OTR rules may require cancellation within 30 days. Failure to cancel can lead to additional tax, interest, and penalties.
New DC Homeowner Checklist
New owners should not assume the old owner’s bill, Homestead status, mailing address, or escrow setup is correct. Review your property record soon after settlement.
- Search the property using the address or Square/Suffix/Lot from your settlement documents.
- Compare the tax bill with your closing disclosure and lender escrow setup.
- Check whether Homestead is present and whether you must apply in your own name.
- Confirm the mailing address for future tax bills and benefit notices.
- Review whether you need a new-owner assessment appeal.
- Save settlement papers, bill copies, benefit applications, and payment proof together.
Closing warning: A seller credit on your settlement statement is not the same as a posted OTR tax payment. Check the official account after closing.
Mortgage Escrow Checklist
If your mortgage company pays DC property taxes, you should still monitor the OTR record. Escrow money collected by a lender is not the same as a real property payment being posted to your DC tax account.
- Check the first-half bill before March 31.
- Check the second-half bill before September 15.
- Compare the OTR bill with your mortgage escrow statement.
- Ask your servicer for proof if payment has not posted close to the due date.
- Do not pay personally until you know whether the servicer is paying.
- Save OTR payment status and servicer proof together.
DC Assessment Appeals and Benefit Appeals
If the issue is assessed value, property classification, or a denied Homestead or senior/disabled benefit, the payment screen will not solve the problem. You may need an appeal through OTR, RPTAC, or another official route depending on the decision and stage.
- Review the proposed or final assessment notice.
- Start with the First Level Administrative Review when required.
- File by the stated deadline, such as April 1 or the new-owner deadline where applicable.
- If you disagree with the administrative decision, review RPTAC appeal rules.
- Keep payment deadlines separate from assessment appeal deadlines.
- Open MyTax.DC.gov.
- Search the real property by address or SSL.
- Open “Applications and Actions.”
- Choose the benefit appeal option if Homestead or Senior/Disabled relief was denied.
- Submit the appeal within the official 45-day decision-letter window where applicable.
Late Taxes, Penalty, Interest and DC Tax Lien Sale Risk
If DC real property taxes, BID taxes, vault rent, penalties, interest, or certified taxes remain unpaid, the property can move toward tax lien sale procedures. Treat any tax-sale or delinquency notice as urgent.
- Search your real property account on MyTax.DC.gov.
- Confirm the delinquent period, balance, penalty, and interest.
- Compare any notice with the official OTR tax sale page.
- Contact OTR before the sale date if you are trying to prevent sale.
- If a certificate has been sold, review redemption rights and deadlines immediately.
Urgent note: Tax lien sale, redemption, bankruptcy, probate, foreclosure, business ownership, trust ownership, or court disputes can be legal and time-sensitive. Use OTR instructions and qualified professional help if a deadline or legal notice is involved.
Common DC Property Tax Mistakes to Avoid

March 31 and September 15 relate to different bill periods.
Owner-occupants should verify Homestead status and apply if eligible.
If eligibility changes, relief may need to be canceled within 30 days.
Escrow collection does not guarantee posted OTR payment.
Tax lien sale notices need immediate official review.
