Businesses operating in Washington, D.C., should begin preparing for another change to the District’s general sales and use tax rate.
Beginning October 1, 2026, the general D.C. sales tax rate will increase from 6.5% to 7%. The change will generally affect taxable sales of tangible personal property, digital goods, and taxable services.
The increase may appear small, but businesses that fail to update their systems on time could collect the wrong amount from customers, create inaccurate invoices, underpay the District, or be required to cover the difference themselves.
What Is Changing on October 1?
The District’s general sales tax rate was previously 6%. It increased to 6.5% on October 1, 2025, and will increase again to 7% for taxable periods beginning on or after October 1, 2026.
The D.C. Office of Tax and Revenue announced the scheduled increase in its official notice regarding D.C. tax changes.
The current D.C. Code also provides that the general rate is:
- 6% before October 1, 2025.
- 6.5% from October 1, 2025, through September 30, 2026.
- 7% beginning October 1, 2026.
The statutory language can be reviewed in the D.C. Code provision imposing the sales and use tax.
What Types of Sales Will Be Affected?
The 7% general rate will generally apply to taxable sales involving:
- Tangible personal property.
- Digital goods.
- Certain taxable services.
- Taxable retail merchandise.
- Equipment and supplies sold to customers.
- Certain software, digital products, and electronic content.
- Other transactions subject to the D.C. general sales and use tax.
Whether a particular transaction is taxable depends on what is being sold, where the sale occurs, where the customer receives the product or service, and whether a specific exemption or special rate applies.
The rate increase does not mean that every transaction in Washington, D.C., will automatically be taxed at 7%. Some products and industries are subject to special rates, while other transactions may qualify for an exemption.
Businesses should not assume that the general rate applies to every sale without first reviewing the tax treatment of their products or services.
How Much Difference Will the Increase Make?
Under the current 6.5% general rate, a business making a taxable sale of $100 collects $6.50 in D.C. sales tax.
Beginning October 1, the same $100 taxable sale will require the business to collect $7 in sales tax.
For one transaction, the difference is only 50 cents. However, the difference becomes more significant when a business processes hundreds or thousands of transactions.
For example, a business with $10,000 in sales subject to the general rate would collect:
- $650 under the 6.5% rate.
- $700 under the new 7% rate.
The difference would be $50 for every $10,000 of taxable sales.
A business that continues collecting 6.5% after the new rate becomes effective may still owe D.C. the full 7%. Depending on the circumstances, the business may have to pay the uncollected difference from its own funds.
Which Businesses Should Prepare for the Change?
The increase may affect many businesses that make taxable sales in Washington, D.C., including:
- Retail stores.
- Online sellers.
- Contractors who sell taxable materials or products.
- Technology and software businesses.
- Businesses selling digital goods.
- Beauty and personal-service businesses with taxable retail sales.
- Event vendors.
- Food businesses that sell items subject to the general rate.
- Consultants and service providers offering taxable services.
- Businesses located outside D.C. that have a sales tax collection obligation in the District.
A business does not necessarily have to maintain a physical storefront in Washington, D.C., to have a D.C. sales tax responsibility.
Online sellers and businesses located in Maryland, Virginia, or another jurisdiction may need to collect D.C. tax when they have sufficient business activity in the District and make taxable sales to D.C. customers.
What Should Businesses Update?
Businesses should review every system used to calculate, collect, record, or report sales tax.
Before October 1, businesses should consider updating:
- Cash registers.
- Point-of-sale systems.
- Online stores.
- E-commerce platforms.
- Accounting and bookkeeping software.
- Invoicing programs.
- Payment terminals.
- Recurring billing systems.
- Written price lists.
- Customer contracts.
- Sales-tax calculation settings.
- Internal bookkeeping procedures.
Businesses using programs such as QuickBooks, Square, Shopify, Stripe, PayPal, or other payment and accounting platforms should confirm whether the rate will update automatically.
An automatic update should never be assumed. The business should test its system before processing sales under the new rate.
Review Contracts and Invoices That Cross the Effective Date
Businesses should pay special attention to projects that begin before October 1 but are invoiced, delivered, or completed after the rate change.
The correct tax rate may depend on factors such as:
- When the sale occurs.
- When the product is delivered.
- When the customer takes possession.
- When the taxable service is performed.
- When the invoice is issued.
- Whether a deposit was collected.
- Whether the agreement includes taxable materials.
- Whether the business uses cash- or accrual-based records.
A contract signed in September does not necessarily guarantee that the 6.5% rate will apply if the taxable transaction occurs after October 1.
Businesses with deposits, installment payments, recurring subscriptions, or long-term projects should review the timing of each transaction instead of relying only on the date the agreement was signed.
Sales Tax Collected Is Not Business Income
Sales tax collected from customers is not generally money that belongs to the business. The business collects the tax on behalf of the District and must report and remit it properly.
For example, if a business charges a customer $107 for a $100 taxable item after October 1:
- $100 represents the business’s taxable sale.
- $7 represents D.C. sales tax collected from the customer.
The full $107 may enter the business’s bank account, but the $7 should be recorded separately as sales tax payable rather than ordinary business revenue.
Failing to separate sales tax from income can make financial records inaccurate and may cause the business to spend money that must later be paid to the District.
Businesses Must Continue Filing Required Returns
Every individual or business required to collect D.C. sales tax must file the applicable sales and use tax returns, even when the business had little or no taxable activity during the filing period.
The D.C. Office of Tax and Revenue explains its general filing requirements in the official Sales and Use Tax Frequently Asked Questions.
Businesses should verify:
- Their required filing frequency.
- The correct tax period.
- The applicable tax rate.
- The amount of gross sales.
- The amount of taxable sales.
- Exempt sales.
- Tax collected from customers.
- Credits or adjustments.
- The payment deadline.
Returns and payments are generally managed through the District’s online tax portal, MyTax.DC.gov.
Special Sales Tax Rates May Still Apply
The change to 7% applies to the general D.C. sales and use tax rate. Washington, D.C., also maintains separate rates for certain categories of transactions.
Depending on the business activity, different rates may apply to areas such as:
- Restaurant meals and certain prepared food.
- Alcoholic beverages consumed on the premises.
- Hotels and transient accommodations.
- Parking and vehicle storage.
- Rental vehicles.
- Commercial bingo.
- Other specially classified transactions.
A business currently collecting a special rate should not automatically replace that rate with 7%.
The business should first determine whether its transactions are subject to the general rate or a separate rate established under D.C. law.
What Happens If a Business Collects the Wrong Rate?
Collecting too little sales tax does not necessarily eliminate the business’s obligation to pay the correct amount to D.C.
If the business collects 6.5% when it should have collected 7%, the Office of Tax and Revenue may still assess the additional tax. Interest and penalties may also apply when taxes are reported or paid late.
Collecting too much can also create problems. A business should not intentionally charge customers more than the legally applicable rate.
When an incorrect rate has been used, the business should review the affected transactions, correct its systems promptly, preserve its records, and determine whether amended returns or customer refunds may be necessary.
Steps Businesses Should Take Before October 1
D.C. businesses should begin preparing before the effective date instead of waiting until the first day of the new rate.
A practical preparation process should include:
- Identify every product and service the business sells.
- Determine which transactions are subject to D.C. sales tax.
- Separate transactions taxed at the general rate from those subject to special rates.
- Update accounting, invoicing, and point-of-sale systems.
- Review recurring invoices and subscriptions.
- Test the new 7% calculation.
- Train employees who prepare invoices or accept payments.
- Review contracts that cross the October 1 effective date.
- Confirm that sales tax is recorded separately from business income.
- Retain reports showing when the system was updated.
Businesses with locations or customers in Maryland, Virginia, and Washington, D.C., should be especially careful. Each jurisdiction has its own rules, rates, exemptions, filing systems, and deadlines.
The Most Important Point
Beginning October 1, 2026, Washington, D.C.’s general sales tax rate will increase from 6.5% to 7%.
Businesses should not wait until October to review their systems. Point-of-sale programs, online stores, invoices, accounting software, recurring billing arrangements, and employee procedures should be reviewed before the new rate takes effect.
A small rate difference can become a substantial liability when applied across months of taxable sales.
