How Much Is $100,000 Taxed in Washington, DC?

When it comes to taxation, Washington, D.C. has a progressive income tax system that increases based on income brackets. If you're earning $100,000 in Washington, D.C., understanding how much of your income will be taxed can help you plan your finances better.

Here’s a breakdown of how much tax you can expect to pay on a $100K income as of 2025:

Federal Income Tax

First, you’ll need to pay federal income tax. The federal tax system is also progressive, meaning the more you earn, the higher the rate at which your income is taxed. For 2025, here are the applicable tax brackets for a single filer:

• 10% on income up to $11,000
• 12% on income from $11,001 to $44,725
• 22% on income from $44,726 to $95,375
• 24% on income from $95,376 to $182,100

Since $100,000 falls into the 24% bracket, you would owe taxes in the following way:

• The first $11,000 is taxed at 10% → $1,100
• The next $33,725 (from $11,001 to $44,725) is taxed at 12% → $4,047
• The next $50,650 (from $44,726 to $95,375) is taxed at 22% → $11,143
• The remaining $4,625 (from $95,376 to $100,000) is taxed at 24% → $1,110

Adding it all together, your federal tax liability would be approximately $17,400.

D.C. Income Tax

Washington, D.C. also has a progressive income tax system, with tax brackets that range from 4% to 10.75%. The 2025 tax rates for D.C. are as follows:

• 4% on income up to $10,000
• 6% on income from $10,001 to $40,000
• 6.5% on income from $40,001 to $60,000
• 8.5% on income from $60,001 to $250,000
• 9.25% on income from $250,001 to $500,000
• 10.75% on income over $500,000

For a $100,000 income, you would fall into the 8.5% bracket, with taxes calculated as follows:

• The first $10,000 is taxed at 4% → $400
• The next $30,000 (from $10,001 to $40,000) is taxed at 6% → $1,800
• The next $20,000 (from $40,001 to $60,000) is taxed at 6.5% → $1,300
• The remaining $40,000 (from $60,001 to $100,000) is taxed at 8.5% → $3,400

Adding these up, your D.C. income tax liability would be $6,900.

Social Security and Medicare Taxes

In addition to federal and D.C. income taxes, you also have to pay payroll taxes for Social Security and Medicare. These taxes are set at fixed rates:

• Social Security: 6.2% on income up to $160,200 for 2025 → $6,200 on your $100,000 income
• Medicare: 1.45% on all income → $1,450 on your $100,000 income

So, your total Social Security and Medicare tax liability would be $7,650.

Total Tax Liability

Now, let’s calculate your total tax burden by adding up all the taxes:

• Federal Income Tax: $17,400
• D.C. Income Tax: $6,900
• Social Security and Medicare Taxes: $7,650

The total tax liability on your $100,000 income would be $31,950.
