Map the business before choosing forms
Start with the legal entity, federal tax classification, ownership, DC activities and revenue sources. Corporations may need the DC corporate franchise return. Other businesses may fall under the unincorporated business franchise tax, subject to filing rules and exemptions. A federal S election does not by itself answer the DC franchise-tax question.
The DC Office of Tax and Revenue describes a personal-services exemption for certain unincorporated businesses. Review its income and capital tests instead of assuming every consultant or LLC is exempt.
Separate the recurring accounts
Sales and use tax, employer withholding and franchise tax are different obligations. Register applicable accounts through the District’s tax system and keep the registration confirmations. Filing a business-license application is not a substitute for completing tax registration.
Create a calendar from the actual filing frequency assigned to each account. Record both return deadlines and payment requirements. An extension to submit a return generally does not extend the time to pay the underlying tax.
Keep evidence for the local return
Use a reconciled ledger and retain payroll reports, customer invoices, expense records and owner-payment details. Track where services are performed and where business activity occurs if the company also operates in Maryland or Virginia. Multistate allocation requires more than the address printed on an invoice.
Read notices promptly and compare them with filed returns and payment confirmations. Bring unresolved notices and account history to your preparer. Keep the account list current when the entity adds owners, employees or another line of business.
