How to Register for a Maine Seller’s Certificate
MRegister online through Maine Revenue Service:
- Complete the online registration.
- Provide your business information and EIN or SSN.
- Receive your Seller’s Certificate.
- Begin collecting sales tax.
Registration is free and is typically processed within a few business days. Don’t start collecting tax before your certificate is issued: collecting sales tax without authorization is itself a violation.
Pro tip: open a separate bank account or sub-account specifically for sales tax funds you collect. This money isn’t yours. It belongs to the state, and commingling it with operating funds is how businesses end up unable to pay when filing deadlines arrive.
