TL;DR
DC taxes most residential property at $0.85 per $100 of assessed value. The Office of Tax and Revenue sets assessments every January 1, and homeowners appeal first through an OTR administrative review, then to the Real Property Tax Appeals Commission. The first-level deadline is April 1. No attorney or contingency firm required.
What is the DC property tax rate and how does it work?
Washington, DC taxes real property under a tiered classification system. Most owner-occupied homes and condos fall into Class 1 and pay $0.85 per $100 of assessed value. [1] Rental residential property with five or more units falls into Class 2 at $1.65 per $100. Commercial property, Class 3 vacant land, and Class 4 blighted property carry much higher rates.
The tax hits the assessed value, not the price you paid. DC law requires the Office of Tax and Revenue (OTR) to assess property at 100% of estimated market value. [9] In practice, assessments often trail the market by six to twelve months because OTR uses a single January 1 valuation date each year.
Your bill arrives in two installments. The first half is due March 31, the second September 15. [1] Miss either and interest runs at 1.5% per month.
Here's a distinction that trips people up. The assessment is the dollar value OTR places on your home. The property tax is the bill you actually pay: that assessed value times the rate per $100, minus any exemptions. A high assessment doesn't automatically mean you overpay. It does mean you probably will unless you act.
DC collected roughly $4.1 billion in real property taxes in fiscal year 2023, one of the District's largest revenue sources. [3]
How does the DC property tax assessment process work?
Every January 1, OTR values every parcel in the District as of that date. Notices go out in late winter or early spring, and the assessment you receive applies to the tax bill you start paying the following March. [2]
OTR runs a mass appraisal model. Assessors don't walk through every home every year. They feed comparable sales, neighborhood data, square footage, lot size, condition codes, and permit records into valuation software. Efficient, yes. Error-prone, also yes. A bathroom remodel that skipped the permit process might not register in the model. A lot next to a sinkhole might get treated like the flat one across the street.
The notice OTR mails you lists three things: last year's assessed value, the proposed new value, and the first-level appeal deadline of April 1. [2] Keep that notice. It's the starting point for any appeal.
You can check your current assessment any time through OTR's public real property database. [4] It shows the sales history and the property characteristics OTR is working from. Pull your record before you appeal and read every field: square footage, bedroom count, bathroom count, lot size, condition. Wrong numbers in those fields are the easiest wins there are.
What DC property tax exemptions can lower your bill before you appeal?
Before you fight the assessment, check whether an exemption already applies to you. Several DC programs cut the bill on their own.
The Homestead Deduction gives owner-occupants a flat $84,900 reduction in assessed value and caps the annual assessment increase at 10%, no matter what the market does. [5] Own it, live in it, and haven't filed the one-time application? You're overpaying right now. The form is DC Form FP-100.
The Senior Citizen or Disabled Property Owner relief program caps the annual tax increase at 5% for qualifying owners. [5] Income limits apply, so confirm the current threshold with OTR.
Veterans with a 100% service-connected disability pay no DC property tax on their primary residence. [5]
Low-income homeowners and renters may qualify for the Schedule H property tax credit, claimed on the DC individual income tax return. [5]
None of this is automatic. You have to apply. Homeowners leave thousands on the table for years because nobody told them the application existed. File the Homestead Deduction the week you close on a DC home.
| Exemption / Benefit | Who Qualifies | Annual Benefit |
|---|---|---|
| Homestead Deduction | Owner-occupants | $84,900 off assessed value + 10% assessment cap [5] |
| Senior / Disabled Relief | Age 65+ or disabled, income limits | 5% annual tax increase cap [5] |
| 100% Disabled Veteran | VA-certified 100% disability | Full exemption on primary residence [5] |
| Schedule H Credit | Low-to-moderate income renters/owners | Credit against DC income tax [5] |
Should I appeal my property tax assessment in DC?
Yes, if your assessment sits higher than what comparable homes actually sold for near January 1 of the valuation year. That's the whole test.
Appeals win a real share of the time in DC. The Real Property Tax Appeals Commission (RPTAC) reduces assessments in a meaningful portion of contested cases, and OTR's own administrative review settles many disputes before they ever reach a formal hearing. Nobody publishes a clean annual win rate. The honest answer is that no one has reliable public data on it, and practitioner estimates land somewhere in the 30% to 50% range for cases that get contested with solid evidence.
The math favors a DIY appeal even on a modest home. Say OTR overvalued your $700,000 rowhouse by 10%. That's $70,000 in excess assessed value. At the Class 1 rate of $0.85 per $100, you're overpaying about $595 a year. [1] Worse, that inflated number becomes the base for future increases under the Homestead cap.
When should you skip it? If real comparables support your assessed value, or if your assessment already sits below what similar homes sold for, filing wastes your time. DC's process rarely raises an assessment unless you hand them new value evidence yourself, but there's no upside in poking at a number that's already fair.
Run one check before filing. Pull three to five arm's-length sales of homes like yours that closed between July 1 and December 31 of the year before your valuation date. If they average below your assessed value, you have a case.
What are the DC property tax appeal deadlines?
Miss the deadline and your appeal for that year is over. There is no grace period.
| Appeal Stage | Deadline | Where to File |
|---|---|---|
| First-level Administrative Review (OTR) | April 1 following receipt of assessment notice [2] | OTR online portal or in person |
| Real Property Tax Appeals Commission (RPTAC) | Within 90 days of OTR's decision on the admin review [6] | RPTAC, 441 4th St NW |
| DC Superior Court (final appeal) | Within 6 months of RPTAC final order [6] | DC Superior Court |
The April 1 date applies to the assessment notice you get in late winter or early spring. If April 1 lands on a weekend or holiday, the deadline moves to the next business day. [2]
A separate track exists. You can also contest the assessed value on a prior tax bill you believe was excessive, but that window is shorter (usually six months from the bill date). Most homeowners should build their case around the spring assessment notice.
New construction or a property that got a supplemental mid-year assessment gets its own notice and its own 60-day appeal window. [2] Watch the mail for those.
How do I appeal my DC property tax assessment: step by step
The DC appeal has two formal tiers before court. Most cases end at the first one.
Step 1: Pull your property record. Open OTR's public property database and confirm the data for your parcel. [4] Write down every error: wrong square footage, a bathroom that doesn't exist, a "finished" basement that's really bare concrete. Photograph anything that shows condition problems.
Step 2: Gather comparable sales. You want arm's-length sales of similar homes that closed between July 1 and December 31 of the year before your valuation date. Use the DC Recorder of Deeds records, Zillow's sold filter, or Redfin's sold listings. [10] Stay within a half mile, same property type, similar size and age. Three to five solid comps is enough. A wide gap between those sale prices and your assessed value is your whole argument.
Step 3: File the first-level administrative review with OTR. Free and informal. Submit online through the MyTax portal or mail Form FP-31. [8] Attach your comp printouts and any condition photos. Add a short written explanation of why the assessment is too high. Keep it factual.
Step 4: Let OTR review it (or attend if asked). An OTR assessor reviews your submission. Many reductions happen right here, no hearing needed. If OTR drops the assessment to something reasonable, you're done.
Step 5: Appeal to RPTAC if the OTR result falls short. File a petition with the Real Property Tax Appeals Commission within 90 days of OTR's final determination. [6] RPTAC hearings are more formal. You present evidence, the OTR assessor responds, and a hearing officer decides. Represent yourself. RPTAC's procedures are posted on its site. [6]
Step 6: DC Superior Court, only if you must. After the administrative process, you can appeal to Superior Court. This step really does call for an attorney for most people. Almost no homeowner gets here.

Can I appeal my DC property tax assessment online?
Yes. OTR's first-level administrative review files through the MyTax portal. [8] You create an account, find your property, and submit the appeal form with digital attachments (PDFs of comp sales, photos, any appraisal you have). The portal runs year-round, but your submission only counts if it lands before April 1.
RPTAC filings aren't fully online as of 2025. RPTAC takes petitions by mail or in person at 441 4th Street NW, Suite 360S. [6] Check its site for any changes to filing procedures.
One warning. The MyTax portal chokes near the April 1 deadline when everyone files at once. Don't wait until March 31. File at least a week early and save the confirmation email or a screenshot of the confirmation screen.
What evidence wins a DC property tax appeal?
Comparable sales win appeals. An arm's-length sale is the best evidence of market value, and DC's assessment standards lean on the sales comparison approach for residential property. [9] Your comps need to be close in time (within six months of the January 1 valuation date, ideally), close in location, and close in size and type.
Second best is a licensed appraisal. A full USPAP-compliant appraisal from a DC-licensed appraiser carries weight at RPTAC because it's a professional value opinion built on the same method assessors use. Appraisals run $400 to $800 in the DC market, so weigh that against your projected tax savings first.
Photos matter for condition disputes. If OTR assumes "average" condition but your home has a cracked foundation, dead HVAC, or years of deferred maintenance, photos plus contractor repair estimates justify a condition adjustment.
Data errors are free money. If OTR's record says 2,100 square feet and your actual interior is 1,750, that gap directly inflates the assessment. A floor plan, the original building permit, or a tape measure and a hand sketch documents it.
What falls flat: complaints about the economy, your personal finances, or what you paid five years ago. Assessors care about current market value near the valuation date. Nothing else.

How to write a property tax assessment appeal letter for DC
The OTR first-level review doesn't demand a formal letter, but a clear written statement stapled to your Form FP-31 submission helps the assessor grasp your case fast.
Keep it to one page. State your name, address, parcel (square and lot number), the assessed value you're contesting, and the value you believe is correct. Then give two or three reasons, each tied to an attachment.
A clean structure looks like this:
1. Identify the assessment and the reduction you want (specific numbers). 2. Lead with your strongest comparable sale: address, sale date, price, and how it stacks against your home. 3. Note any OTR data errors you found in your record. 4. Point to condition issues with photos or estimates attached. 5. Close with the value you believe is correct and ask OTR to adjust.
Skip the emotion. Don't write about how much you've poured into the home or how unfair the jump feels. Assessors move on market data, not hardship.
At the RPTAC stage the petition form is more structured, but the rule holds: every claim points to a specific piece of evidence in your package. RPTAC's hearing examiners read stacks of these. Brevity backed by specifics reads well.
What happens after you win a DC property tax appeal?
If OTR lowers your assessed value at the administrative review stage, the corrected number flows into your next bill on its own. Already paid the higher bill? OTR issues a refund or credits your next payment. Refunds generally process within 30 to 60 days of the adjustment, though OTR notes processing times vary. [2]
Win at RPTAC and the Commission issues a final order directing OTR to adjust. Same refund process follows.
Here's what people miss. A win in one year doesn't lock in that lower value forever. OTR reassesses every January 1, and your value can jump again the next spring. The Homestead Deduction's 10% cap softens the blow, but only if you've filed it. Because the cap applies to assessed value, a lower starting point from a successful appeal compounds into lower taxes down the road.
Read your notice every February. If the new value runs past what comparables support, the process resets and you file again. Repeat appeals in a rising market are normal for DC owners who stay on top of their bills.

How does DC property tax compare to other major cities?
DC's nominal residential rate of $0.85 per $100 sits low next to many large US cities. [1] But the real burden depends on how closely assessments track market value and what exemptions exist.
| Jurisdiction | Residential Rate (per $100 AV) | Notes |
|---|---|---|
| Washington, DC | $0.85 [1] | Homestead cap limits annual assessment growth to 10% |
| New York City (Class 1) | ~$0.21 (effective) | Very low nominal rate, assessments far below market value |
| Chicago (Cook County) | ~$6.60 (per $100 EAV at 10% level) | Complex equalizer system; see Cook County property tax |
| Los Angeles County | ~$1.00 base rate | Prop 13 caps growth at 2%/year; see Los Angeles County property tax |
| Fairfax County, VA | ~$1.135 per $100 | No annual assessment cap like DC's Homestead; see Fairfax County property tax |
The headline rate lies. A city with a low rate but assessments pinned at 100% of market value (DC's aim) can produce a higher effective tax than a city with a fat nominal rate on heavily discounted assessments. The effective rate, annual taxes divided by sale price, is the honest comparison. The Lincoln Institute of Land Policy runs an annual survey of effective rates that lets you line up cities side by side. [7]
Frequently asked questions
Should I appeal my property tax assessment in DC?
Appeal if comparable homes in your neighborhood sold for less than your assessed value near the January 1 valuation date. The OTR first-level review is free and takes about an hour to prepare. If your assessed value already sits conservative against sales, skip it. A 10% overassessment on a $700,000 DC rowhouse costs roughly $595 a year at the Class 1 rate of $0.85 per $100, so the math usually favors filing.
How do I appeal my DC property tax assessment?
File a first-level administrative review with OTR by April 1. Submit Form FP-31 with comparable sales showing your home's market value is below the assessed figure. If OTR doesn't cut it enough, file a petition with the Real Property Tax Appeals Commission (RPTAC) within 90 days of OTR's decision. You can represent yourself at both stages. No attorney required.
How can I appeal my property tax assessment in DC?
Online through the MyTax portal for the OTR first-level review, or by mailing Form FP-31 to OTR. Attach comparable sales, photos documenting condition issues, and a short written explanation of the error. For the second level, petition RPTAC at 441 4th Street NW, Suite 360S. Both are self-service and both are free.
Can I appeal my property tax assessment online in DC?
Yes. The OTR first-level administrative review files through the MyTax portal. You create an account, find your parcel, and upload your documents. RPTAC filings aren't fully online as of 2025 and go by mail or in person. Don't file the OTR appeal on the last day. The portal gets congested near the April 1 deadline.
What is the DC property tax appeal deadline?
April 1 following receipt of your annual assessment notice for the OTR first-level review. After OTR decides, you have 90 days to file with RPTAC. After RPTAC, you have 6 months to appeal to DC Superior Court. All deadlines are firm. If April 1 falls on a weekend or holiday, the next business day applies.
What is the DC residential property tax rate?
Class 1 residential property (owner-occupied homes and condos with 1-4 units) is taxed at $0.85 per $100 of assessed value. Rental residential with 5+ units is Class 2 at $1.65 per $100. Vacant commercial property is Class 3 at $5.00 per $100. The rate applies to the full assessed value minus any approved deductions or exemptions.
What is the DC Homestead Deduction and how do I apply?
The Homestead Deduction reduces your assessed value by $84,900 and caps annual assessment increases at 10% for owner-occupied primary residences. It's a one-time application using DC Form FP-100 from OTR. Apply as soon as you move into a DC home you own. Many owners miss years of savings by not knowing the application is required.
What evidence do I need for a DC property tax appeal?
Comparable sales are strongest: three to five arm's-length sales of similar homes that closed within six months of January 1 of the valuation year. Also useful: a licensed appraisal ($400 to $800 in DC), photos and contractor estimates for condition issues, and documentation of errors in OTR's property record (wrong square footage, wrong bedroom count, and the like).
What is the difference between property tax and a tax assessment in DC?
The tax assessment is the dollar value OTR places on your property, meant to reflect 100% of market value as of January 1. The property tax is the bill you pay: your assessed value times the rate per $100, minus exemptions. A high assessment drives a high bill, which is why contesting the assessment directly lowers what you owe.
How long does a DC property tax appeal take?
OTR first-level administrative reviews typically take 4 to 8 weeks after the filing deadline. RPTAC hearings get scheduled after OTR issues its decision and can add several months. Total time from an April filing to a final RPTAC decision often runs 6 to 10 months. Refunds or credits for overpaid taxes generally process within 30 to 60 days of a favorable final decision.
Do I need a lawyer or tax agent to appeal my DC property tax?
No. Both the OTR administrative review and RPTAC hearings are built for self-service. You don't need an attorney at either stage. Contingency firms typically take 25% to 50% of the first year's tax savings for work you can do yourself. The DC Superior Court appeal is different and likely does require legal representation if you reach it.
Can seniors get a lower property tax rate in DC?
Yes. DC's Senior Citizen or Disabled Property Owner Tax Relief caps annual property tax increases at 5% for qualifying owners age 65 or older. Income limits apply. Separately, the standard Homestead Deduction (open to all owner-occupants) caps assessment increases at 10%. Seniors who qualify for both get the more favorable 5% cap. Applications go through OTR.
What happens if I win my DC property tax appeal?
OTR adjusts your assessed value, which lowers your bill going forward. If you already paid the higher amount, OTR issues a refund or credits your next bill, typically within 30 to 60 days of the adjustment. Winning one year doesn't freeze your assessment permanently. OTR reassesses every January 1, so watch your notice each spring.
Where do I find comparable sales for a DC property tax appeal?
OTR's public real property database includes recent sales by neighborhood. The DC Recorder of Deeds lists recorded sale prices. Zillow, Redfin, and Realtor.com all have sold filters. Target homes within half a mile, same property type, similar square footage, that closed between July 1 and December 31 of the year before your valuation date.
