Follow these simple steps to allow Taxually to file tax returns for your company:

Finding the Required Onboarding Information

• Log in to MyTaxIllinois

  • Confirm the settings are as follows:

    • Allowed: Yes

  • Navigate to the Summary tab

  • Locate your ST-1 Sales/Use Tax account 

  • Provide the 8-digit code listed under “Account” (format 1234-5678) 

• Zip/Postal Code

  • For US Zip Codes: Provide the 9-digit zip/postal code provided on your ST-1 Sales/Use Tax account tile (format 12345-1234)

  • For Other Postal Codes: Confirm that the postal code matches the legal address you provided to Taxually in the Business Details section. If different, please provide Taxually with the zip/postal code of your registered address in Illinois.

  • If you do not have a zip/postal code (due to your registered country), enter "N/A" and follow the alternative third-party access instructions below.

• Filing Frequency

  • Click File a Return on the ST-1 Sales/Use Tax account tile

  • Review the Periods listed to determine the filing frequency

• For Accounts with a Payment History: Skip to the next section if you do not have a payment history

  • Click Manage Payments and Returns on the ST-1 Sales/Use Tax account tile

  • From the Show dropdown fields select Payments and Posted

  • Provide the Payment Amount from the most recently posted payment

ALTERNATIVE THIRD-PARTY SETUP INSTRUCTIONS: 

For Accounts without a Payment History or Zip/Postal Code:

For accounts without a payment history or a zip/postal code, we are unable to request standard third-party access from our existing Taxually third-party account. Instead, you need to create a temporary additional logon for Taxually. If you have a zip/postal code but no payment history, Taxually will request standard third-party access after your first payment is processed.

Effective Registration Date

You are only required to provide this date if Taxually is submitting your first return. 

Your effective registration date can be found in the mailed registration confirmation documents for your ST-1 Sales/Use Tax account. You should receive a "Taxpayer Notification - Electronic Filing" letter. This letter will include your "Electronic filing effective" date. Please provide this date formatted as MM/DD/YYYY.

Alternative: If you do not have access to this letter, you can provide the "Start Date" you used for your Illinois Sales Tax registration application (the date you created a tax obligation).

Ideally, you should provide the date listed on the Electronic Filing letter mentioned above.
