Before setting up payroll in Atto, you’ll need to gather specific documents that verify your company’s tax IDs. Having this information ready helps ensure a smooth and compliant onboarding experience.
What You’ll Need
1. Employer Identification Number (EIN)
Used to report income taxes and employer payroll taxes to the IRS.
Look for your EIN on:
Form 941 – Employer’s Quarterly Federal Tax Return
IRS Letters or Notices
Online IRS Account
Or call the IRS Business & Specialty Tax Line: 1-800-829-4933
2. State and Local Tax ID Numbers
These are required for state income tax, state unemployment tax, and local tax compliance.
Look for your State ID(s) on:
State Quarterly Wage Reports
State Unemployment Tax (SUTA) Forms
Previous State or Local Tax Filings
Or contact your state’s Department of Revenue or Taxation
Missing a State ID?
If you’ve applied but haven’t received your State Tax ID yet, you can proceed by selecting “Applied for but not yet received” during setup.
📌 Just remember to update it in your Atto account as soon as it’s issued to avoid processing delays or penalties.
