What Information Do You Need to Register for Sales Tax?
Why states ask for detailed information during sales tax registration
Sales tax registration creates your state sales tax account so you can collect, report, and remit sales tax when required. States use your registration details to:
- Confirm your business identity and responsible parties
- Determine filing frequency and account type (sales tax, seller’s permit, vendor certificate)
- Assign the correct jurisdictions (state, county, city, special districts)
- Validate nexus triggers and the date you must begin collecting tax
- Set up payment and compliance notices for returns and due dates
Core business information you should have ready
Legal identity and entity details
- Legal business name (as filed with your state) and any DBA/assumed name
- Entity type (sole proprietor, partnership, LLC, corporation, nonprofit)
- State of formation and formation date (if applicable)
- Business start date and the date you will begin making taxable sales
- NAICS code or business activity description (what you sell and how you sell it)
Federal and state identification numbers
- Employer Identification Number (EIN) or Social Security Number (for certain sole proprietors)
- State business registration number (if your state issues one)
- Other state tax IDs (withholding, unemployment) if already established
Ownership and responsible party information
Most states require details for owners, members, partners, officers, or other “responsible persons.” Prepare:
- Full legal name and title/role
- Home address and phone number
- Date of birth
- SSN/ITIN (commonly requested for identity verification and compliance)
- Ownership percentage (especially for LLCs and corporations)
Business locations and contact details
Physical locations
- Primary business address (physical location, not only a mailing address)
- All additional locations, warehouses, storage, or offices in the state
- Location opening dates (if new locations are planned)
Mailing address and contacts
- Mailing address for notices and returns
- Primary contact name, phone, and email
- Authorized representative details (accountant, payroll provider, or tax professional), if applicable
What you sell and how you sell it
Registration questions often focus on taxable products/services and sales channels. Be ready to describe:
- Products/services sold (including whether you sell taxable goods, taxable services, or exempt items)
- Sales channels (in-store, online, marketplace, wholesale, direct-to-consumer)
- Whether you make sales for resale and issue/accept resale certificates
- Whether you sell to exempt customers (government, nonprofits) and how you document exemptions
Sales tax collection start date and nexus triggers
States typically ask when you began or will begin making taxable sales in the state. You may also be asked what created your obligation to register, such as:
- Physical presence (office, store, warehouse, employees, inventory)
- Economic nexus (sales revenue or transaction count thresholds)
- Temporary presence (trade shows, events, pop-up sales)
- Marketplace activity (whether a marketplace facilitator collects on your behalf)
Estimated sales and filing preferences
Projected taxable sales
Many applications request an estimate of monthly or annual taxable sales. This helps determine filing frequency (monthly, quarterly, annual) and payment requirements.
Return filing and payment setup
- Preferred filing method (online account, paper filing where available)
- Banking details for electronic payment (some states require ACH debit/credit enrollment)
- Third-party access (if you want your accountant to file on your behalf)
Industry-specific details that may be required
Depending on your business activity, you may need additional information such as:
- Alcohol, tobacco, cannabis, fuel, lodging, or other regulated product licensing details
- Contractor information (job sites, project-based work, subcontractors)
- Restaurant/food service details (prepared food, catering, delivery models)
- Drop shipping and fulfillment arrangements (where inventory is stored and shipped)
Practical checklist: gather these items before you start
- Legal name, DBA, entity type, formation details
- EIN/SSN and any existing state tax account numbers
- Owner/responsible party personal details and ownership percentages
- All business locations and contact information
- Description of products/services and sales channels
- Sales tax collection start date and nexus explanation
- Estimated taxable sales volume
- Banking/payment setup details (if required)
State example: New York sales tax registration information
New York generally requests standard identification, ownership, and business activity details, along with information about locations and when sales will begin. If you are registering in New York, review the specific application requirements and fields in the New York sales tax vendor registration application to ensure you have the right information ready.
Submitting your registration: what to expect after you apply
After submission, states may issue your sales tax account number, confirm your filing frequency, and provide instructions for accessing your online account. Keep a copy of your submission confirmation for your records. If you want to see what a confirmation page may look like, visit Application Submitted Successfully.
FAQ: Sales Tax Registration Information Requirements
1) Do I need an EIN to register for sales tax?
Many states allow sole proprietors to use an SSN, but an EIN is commonly preferred and often required for entities like LLCs and corporations. Having an EIN ready can simplify registration and future tax account setup.
2) What address should I use if I run an online business from home?
Use your actual physical business location if requested, even if it is your home office. If you use a separate mailing address for privacy or mail handling, provide that where the application asks for mailing information.
3) Will the state ask for owner SSNs and dates of birth?
Frequently, yes. States use responsible party information to verify identity, assign accountability, and manage compliance for tax collection and remittance.
4) What if I have more than one location in the state?
Be prepared to list each location and its address. Some states create a single account with multiple locations, while others may issue location-based identifiers or require separate location registrations.
5) What start date should I enter for “first taxable sale” if I haven’t opened yet?
Use your planned opening date or the date you expect to begin making taxable sales. If your plans change, update your account promptly so your filing obligations align with actual activity.
6) Do I need to list every product I sell?
Usually not every SKU, but you should provide a clear description of the categories of goods or services you sell and whether they are typically taxable or exempt in that state.
7) What if I sell through a marketplace that collects sales tax for me?
You may still need to register depending on the state and your activities. The application may ask whether a marketplace facilitator collects tax, and you should be ready to explain your sales channels and in-state activities.
8) Why does the application ask for estimated sales?
Estimated taxable sales help the state assign a filing frequency and determine whether additional payment requirements apply. Use a reasonable estimate based on your projections or recent sales history.
9) What banking information might be required during registration?
Some states request bank details for electronic payments or require enrollment for ACH payments. If you do not have banking details available, check whether the state allows you to add payment information after the account is created.
10) Can my accountant or payroll provider submit the registration for me?
Often yes, but the state may require a power of attorney or authorization setup. Have your representative’s contact details ready and confirm whether the state needs additional authorization forms.
