What is the property tax rate in Washington DC?

For owner-occupied and most residential property (Class 1), DC's tax rate is $0.85 per $100 of assessed value, one of the lowest residential property tax rates in the region. Commercial and other Class 2 property is taxed at higher rates of $1.65 or $1.89 per $100 depending on value. DC assesses property at 100% of estimated market value.

What is the DC homestead deduction?

The homestead deduction reduces the assessed value of an owner-occupied principal residence before tax is calculated, lowering your bill. For 2025 the deduction is about $89,850 off the assessed value. To qualify, the home must be your principal residence and you must file a homestead application with the DC Office of Tax and Revenue.

How is DC property tax calculated?

Subtract the homestead deduction (if you qualify) from the assessed value to get the taxable assessed value, then multiply by the class rate and divide by 100. For example, a $600,000 home with the homestead deduction has a taxable value of about $510,150, times $0.85 per $100 equals roughly $4,336 per year.

Does DC offer an assessment cap or senior relief?

Yes. DC caps the annual increase in taxable assessment for owner-occupied homes (the homestead cap), and qualifying seniors and disabled residents can receive a 50% property tax reduction through the senior citizen or disabled property owner relief program. These programs can lower your bill below the basic estimate shown here.

Is this DC property tax estimate exact?

It is a close estimate using the published class rates and the standard homestead deduction. Your actual bill depends on the District's assessed value, your homestead and assessment-cap status, special assessments, and any senior or disability relief. Confirm with your assessment notice and the DC Office of Tax and Revenue.

This estimator calculates annual property tax in the District of Columbia using the real Class 1 residential rate of $0.85 per $100 of assessed value and the homestead deduction for owner-occupied homes. DC assesses property at 100% of market value, and the residential rate is among the lowest in the region.

How it works

DC taxes assessed value at a rate per $100, after the homestead deduction:

Taxable value = Assessed value − homestead deduction (if owner-occupied) Annual tax = Taxable value × rate ÷ 100

Because DC assesses at full market value, there is no separate assessment ratio to apply. The homestead deduction (about $89,850 for 2025) reduces the taxable value for an owner-occupied principal residence, and the class rate depends on whether the property is residential or commercial.

DC property tax rules explained

Class 1 (residential): $0.85 per $100 of assessed value.
Class 2 (commercial): $1.65 per $100 (up to $10M value) or $1.89 above.
Homestead deduction: about $89,850 off assessed value for owner-occupied homes.
DC assesses property at 100% of market value — no fractional assessment ratio.

Worked example

A $600,000 owner-occupied home with the homestead deduction:

Taxable value = $600,000 − $89,850 = $510,150
Annual tax = $510,150 × $0.85 ÷ 100 ≈ $4,336
Monthly ≈ $361
