Set up your Connecticut filing

When setting up your Connecticut return, you'll need to enter the following information.

If you're unsure about any of this information, check your state tax registration certificate or call the Connecticut Department of Revenue at 800-382-9463 (press 3, then 6).

Do you have a physical presence in Connecticut?

Physical presence may include: an office, storefront, employee, salesperson, contractor, warehouse, inventory, or trade show attendance.

  • If you answer YES, you'll be asked how many physical locations you have. You’ll then be asked to provide the address for your in-state physical location.
    • Note: TaxJar only supports users who have a single physical location in the state of Connecticut.

Your Connecticut tax account details

You'll need your sales tax registration information, provided to you by the state when you received your sales tax permit.

When did your tax registration take effect?

Enter the date your business first became liable for Connecticut sales tax. This is when your collection obligations began and should match the date you gave the state when you registered.

State Tax ID

Enter the 10–12 digit sales and use tax ID listed as CT Tax Reg No. in your myconneCT account.

Amount of your last payment to Connecticut

Enter the amount of the last payment you made to the Connecticut Department of Revenue Services in USD. If you haven’t made a payment, enter 0.

Tax filing frequency

Select the frequency assigned to you by the state.

You'll then see the first tax return we expect to file for you, based on the current date and the filing frequency you selected.
