Last updated: Oct 27, 2026, 2:23 PM

To be successful with Toast Payroll and Team Management, register for all applicable tax accounts and supply the tax information to Toast Payroll.

Many tax jurisdictions no longer accept electronic filings and/or deposits with account information in an Applied For status. If not remedied, customers may be assessed penalties, interest fees, and/or additional repercussions by governing agencies.

Tax Management Overview

Many of the items on this page are maintained by your company in the Toast Payroll Tax Center. We highly recommend visiting this page at least once a quarter so you can complete outstanding tasks and help enable a successful quarterly tax filing. Failure to provide this information risks Toast Payroll's ability to remit/file on your behalf, which may result in financial penalties for your company. Visit Toast Payroll: Manage Payroll Taxes to learn all about the Tax Center.

 

After applying for and receiving your state tax account number(s), payment frequency, unemployment rate, or once you complete your third-party administrator (TPA) linking, log into Toast Payroll and select Taxes from the left-hand navigation. Complete any available tasks here, including Form 8655, missing Social Security numbers, and more. (If you do not see Taxes on the left side of the screen, select Payroll from the Toast Web navigation rail on the left to make the Toast Payroll navigation rail appear.)

Where to Find Copies of Tax Filings Processed in Toast Payroll

To find copies of tax filings processed in Toast Payroll, the quarterly tax packages are found within the Toast Payroll system under Reports > Tax Filing. When you select Reports in Toast Payroll, you should see a URL that begins with payroll.toasttab.com. Visit Navigate Toast Payroll Within Toast Web to learn how the new Toast Payroll navigation works.

 

These reports are typically available the third full week of the month following quarter-end. Toast Payroll will only generate tax packages for quarters in which a customer was actively processing payroll within the Toast Payroll system.


Note: Toast Payroll may not be able to complete and/or submit tax filings where the Toast Payroll system reflects missing, erroneous, or incomplete information in a customer's account. It is the customer's responsibility to ensure that they have provided Toast Payroll with all requisite tax information in a timely manner. Copies of tax return submissions do not guarantee that a return was submitted to or accepted by an applicable agency.

Register for Your Payroll Tax IDs

Registration with the state sets up your tax account, identified by an Employer Identification Number (EIN). This number enables Toast Payroll to file electronically on your behalf. Failure to provide this information risks Toast Payroll's ability to remit/file on your behalf, which may result in financial penalties for your company.
