Can Avalara assist with my weekly Illinois prepayments?


You are required to make weekly prepayments to IL and would like to know if Avalara can assist with making them.


Avalara Returns



  • Avalara currently does not support weekly prepayments or filings.

  • To make sure that you are compliant with this requirement, please 

    • Make the prepayments directly with the state

    • Add those payment amounts as prior payments to your liability worksheet.

  • Please contact Illinois state for any questions on making prepayments.

  • If you have already made these payments to the state and need to reduce the amount due on your return, please add the total amount of your prior payments to your liability worksheet.

    • These payments will not automatically pull onto your worksheet.
