Property taxes are one of the largest ongoing costs of DC homeownership, yet many buyers don't fully understand how they work until after closing. Here's what you need to know about DC property taxes — from assessment to payment.
DC Property Tax Rate
DC's residential property tax rate for 2026 is $0.85 per $100 of assessed value (0.85%). This applies to the first $2.5 million of assessed value. Above that, the rate increases.
How It Compares
| Jurisdiction | Effective Rate |
|---|---|
| Washington DC | ~0.85% |
| Arlington, VA | ~1.0% |
| Fairfax County, VA | ~1.1% |
| Montgomery County, MD | ~0.8% |
| Prince George's County, MD | ~1.4% |
DC's rate is competitive for the region, especially after accounting for the homestead deduction.
The Homestead Deduction
DC's homestead deduction is the most important tax benefit for owner-occupants. It reduces your property's assessed value by $91,950 for tax year 2026 before calculating taxes. DC raises the deduction most years, so check the current figure with the Office of Tax and Revenue.
Impact
| Assessed Value | Without Homestead | With Homestead | Annual Savings |
|---|---|---|---|
| $400,000 | $3,400 | $2,618 | $782 |
| $500,000 | $4,250 | $3,468 | $782 |
| $600,000 | $5,100 | $4,318 | $782 |
| $800,000 | $6,800 | $6,018 | $782 |
The savings are the same regardless of your home's value: $782/year (0.85% × $91,950).
How to Apply
- Apply through the DC Office of Tax and Revenue (OTR) website
- Must be filed within one year of purchase
- Takes effect the tax year after approval
- Not automatic — you must apply
- One homestead per person; must be your primary residence
Common Mistake
Many new homeowners forget to apply or assume it happens automatically. If you close in March, you need to apply before March of the following year. Set a reminder.
How DC Assesses Property Value
The DC Office of Tax and Revenue (OTR) assesses all properties annually. Assessed values are based on:
- Recent comparable sales in your area
- Property characteristics (size, age, condition, lot size)
- Market conditions as of January 1 of the tax year
Assessment Cap
DC limits annual assessment increases to 10% for owner-occupied properties with the homestead deduction. If your home's market value jumped 20% in one year, your assessed value can only increase by 10%. This cap provides predictability.
Note: The cap resets when the property sells. New buyers are assessed at the current market value.
Assessment Timeline
- January 1: Valuation date (assessments reflect market as of this date)
- March: Proposed assessments published
- April 1: Deadline to appeal proposed assessments
- October 1: Tax year begins (DC's fiscal year runs Oct 1 - Sept 30)
Appealing Your Assessment
If you believe your assessment is too high, you can appeal:
First Level: OTR Administrative Review
- File by April 1 (deadline for the upcoming tax year)
- Submit comparable sales data showing lower values
- No cost to file
- Decision typically within 60-90 days
Second Level: Board of Real Property Assessments and Appeals (BRPAA)
- If you disagree with the OTR review result
- More formal process with a hearing
- Can submit additional evidence
- Still no cost to file
When to Appeal
Consider appealing if:
- Your assessment increased significantly more than comparable properties
- Comparable homes sold for less than your assessed value
- Your property has condition issues not reflected in the assessment
- An error exists (wrong square footage, lot size, or property characteristics)
Evidence to Gather
- Recent sales of comparable properties (same size, age, neighborhood)
- Photos of condition issues affecting value
- Professional appraisal (if you recently refinanced or purchased)
- Any documentation of problems (structural issues, needed repairs)
How Property Tax Affects Your Mortgage
Escrow Account
Most lenders require an escrow account for property taxes and insurance. Instead of paying taxes directly, you pay 1/12 of the annual amount each month as part of your mortgage payment.
Example: $4,000 annual property tax = $333/month added to your mortgage payment.
Escrow Analysis
Your lender reviews the escrow account annually. If taxes increase, your monthly payment increases to cover the difference. If taxes decrease, your payment may decrease (or you'll receive a refund).
Impact on Qualification
Lenders include property taxes in your DTI calculation. Higher taxes reduce the loan amount you qualify for.
Example: A $500/month property tax obligation reduces your maximum loan amount by approximately $70,000 compared to a property with $200/month in taxes.
Tax Benefits of DC Homeownership
Mortgage Interest Deduction
Deduct interest on up to $750,000 of mortgage debt on your federal taxes. For most DC homeowners, this is a significant deduction in the early years of the mortgage.
Property Tax Deduction
Deduct up to $10,000 in combined state and local taxes (SALT) on your federal return. DC property taxes count toward this cap.
Capital Gains Exclusion
When you sell your primary residence, you can exclude up to $250,000 (single) or $500,000 (married) of capital gains from federal taxes, provided you've lived there for at least 2 of the past 5 years.
Special Situations
Senior Citizen / Disabled Owner
DC offers additional property tax relief:
- Senior citizen tax credit: 50% reduction for qualifying seniors (65+ with income under $143,000)
- Disabled homeowner relief: Similar reductions for qualifying disabled residents
New Construction
Newly constructed or significantly renovated properties may see higher initial assessments. If you buy a new condo, your first full assessment will be based on the purchase price.
Investment Property
Investment properties (rentals) do not qualify for the homestead deduction and pay the full tax rate. They also don't receive the 10% assessment cap. This can result in significantly higher taxes — sometimes 20-25% more than an identical owner-occupied property.
Key Takeaways
- Apply for the homestead deduction immediately after closing — it saves $782/year
- Budget for taxes based on the full assessed value, not a previous owner's capped assessment (the cap resets on sale)
- Review your assessment each March and appeal if it seems too high
- Expect your mortgage payment to change as property taxes adjust annually
- Factor property taxes into your buying decision — they directly affect your monthly payment and qualification amount
DC property taxes are straightforward once you understand the system. The homestead deduction is the single most important action to take after closing — don't forget to apply.
