District of Columbia Small Business Taxes: A 2026 Guide for LLCs and Corporations

Running a business in the District of Columbia means staying on top of more than just sales, hiring, and growth. You also need to understand which taxes apply to your business, how they are calculated, where to file, and when payments are due.

For many owners, DC tax compliance feels complicated because the rules depend on your entity type, payroll activity, and whether you sell taxable goods or services. The good news is that the system is manageable once you break it into the major tax categories.

This guide explains the main District of Columbia small business taxes, the common filing forms, the due dates that matter most, and the records you should keep so tax season is easier to handle.

What taxes can apply to a DC small business?

Most District businesses may need to deal with one or more of the following:

• Corporate franchise tax
• Unincorporated business franchise tax
• Sales and use tax
• Withholding tax for employees
• Unemployment insurance tax
• Estimated tax payments
• Industry-specific taxes or credits, depending on your business activity

Not every business owes every tax. Your obligations depend on whether you operate as a corporation, LLC, partnership, sole proprietorship, or other business structure, and whether you have employees or taxable sales.

Start with your entity type

The first step in figuring out DC business taxes is identifying how your business is classified for tax purposes.

In general:

• Corporations file a corporate franchise tax return.
• Many unincorporated businesses, including LLCs taxed as pass-through entities, partnerships, and sole proprietorships, may file an unincorporated business franchise tax return.
• Businesses with employees usually have payroll-related obligations.
• Businesses selling taxable goods or taxable services may also need to collect and remit sales and use tax.

Because DC tax obligations can overlap, it is common for one business to file multiple returns during the year.

Corporate franchise tax in DC

The District imposes a corporate franchise tax on corporations doing business in DC or earning DC-source income.

For tax year 2025 returns filed in 2026, the corporate franchise tax rate is 8.25%.

A corporation may also owe a minimum tax based on gross receipts:

• $250 minimum tax if DC gross receipts are $1 million or less
• $1,000 minimum tax if DC gross receipts are more than $1 million

Filing deadline

For calendar-year filers, corporate franchise tax returns are generally due on or before April 15.

If your business uses a fiscal year, the return is generally due on the 15th day of the fourth month after the close of the taxable year.

Common forms

• Form D-20, Corporation Franchise Tax Return
• Form FR-120, extension request for corporation returns
• Form D-20ES, estimated franchise tax vouchers

If your business operates within a unitary group, combined reporting rules may also apply.

Unincorporated business franchise tax

Many unincorporated businesses operating in DC may owe unincorporated business franchise tax.

For tax year 2025 returns filed in 2026, the unincorporated business franchise tax rate is also 8.25%.

The same minimum tax structure applies:

• $250 minimum tax if DC gross receipts are $1 million or less
• $1,000 minimum tax if DC gross receipts are more than $1 million

In addition, DC has specific rules for unincorporated businesses, including a filing threshold tied to gross income. If your business has more than $12,000 of gross income, you may need to file Form D-30.

Some businesses may qualify for exceptions or special treatment, so it is worth reviewing the rules carefully before filing.

Filing deadline

For calendar-year filers, the return is generally due on or before April 15.

For fiscal-year filers, the return is generally due on the 15th day of the fourth month after the close of the taxable year.

Common forms

• Form D-30, Unincorporated Business Franchise Tax Return
• Form FR-130, extension request for unincorporated business returns
• Form D-30ES, estimated tax vouchers

Sales and use tax

If your business sells taxable goods or services in the District, you may need to collect and remit sales and use tax.

The DC sales and use tax system applies to the sale, lease, or rental of tangible personal property and certain services. Standard tax rates vary by item or service, so do not assume every sale is taxed at the same rate.

Common rates include:

• 6% for many general sales
• 10% for food and certain prepared beverage sales
• 10.25% for some vehicle rentals and alcohol sold for off-premises consumption
• 15.95% for rooms, lodgings, or accommodations

Use tax may apply when sales tax was not collected on an out-of-state or online purchase used in the District.

Filing deadline

Sales and use tax returns are generally due by the 20th day of the month following the end of your filing period.

For annual filers, the return is generally due by October 20.

Practical tip

If you sell through a marketplace or deliver products into DC from outside the District, review whether nexus rules apply. A business can create a filing obligation even without a physical storefront.

Withholding tax for employees

If your business has employees working in DC, you may need to withhold District income tax from wages.

Employment tax compliance usually starts when you hire your first employee. At that point, you should make sure your payroll system is set up to handle:

• Federal income tax withholding
• DC withholding tax
• Required employee forms
• Periodic tax deposits and filings

DC employers generally use the MyTax.DC.gov portal to manage withholding tax accounts and filing obligations.

Forms and setup

Employers commonly need to keep payroll records and employee withholding forms on file. Make sure your onboarding process is consistent so payroll deductions are correct from the first paycheck.

Unemployment insurance tax

If you have employees, you may also owe unemployment insurance tax through the District of Columbia Department of Employment Services.

The District unemployment tax applies to the first $9,000 of wages paid to each employee.

For newly liable employers, the standard tax rate is the average contribution rate from the prior year or 2.7%, whichever is higher.

That rate remains in effect until the employer is rated based on experience.

Estimated tax payments

If your business expects to owe enough tax during the year, you may need to make estimated payments instead of waiting until the annual return is filed.

Estimated tax helps spread your tax liability throughout the year and can reduce the chance of underpayment penalties.

For both corporate and unincorporated business filers, estimated tax vouchers are generally due:

• April 15
• June 15
• September 15
• December 15

If your business has fluctuating revenue, estimated taxes are especially important to monitor.

How to file and pay DC business taxes

Most business tax filings in the District are handled through the Office of Tax and Revenue.

The main online portal is MyTax.DC.gov. Through it, you can generally:

• File returns
• Make payments
• View account activity
• Manage certain tax accounts and notices

DC also offers forms and instructions for business taxpayers, including franchise tax, sales tax, withholding, and combined reporting documents.

Filing options

Depending on the tax type, you may be able to file:

• Electronically through MyTax.DC.gov
• By mail using the correct paper forms
• Through approved tax software, where available

Electronic filing is usually the most efficient option because it reduces processing delays and helps you keep records in one place.

Recordkeeping that makes tax season easier

Tax filing becomes much simpler when your records are organized throughout the year.

Keep these items in a secure, searchable system:

• Bank statements
• Receipts
• Invoices
• Payroll records
• Sales summaries
• Contractor payments
• Prior-year returns
• Business formation documents
• State and local tax notices

Good recordkeeping is not just about filing a return. It also helps you respond quickly if the District sends a notice or requests verification.

Common mistakes DC business owners make

A few errors show up repeatedly in small business tax filings:

• Missing a filing deadline
• Using the wrong entity type on the return
• Forgetting to register for a required tax account
• Misclassifying taxable sales
• Overlooking estimated tax payments
• Failing to update payroll withholding after hiring employees
• Keeping incomplete books and receipts

These mistakes can lead to penalties, interest, or unnecessary follow-up from the tax authorities.
