At the end of each quarter, we ask that you review important payroll and tax information in isolved for accuracy.
All Q1 2025 payroll and tax information must be accurate and complete in isolved by Monday, March 31, to ensure timely filing.
Below are the recommended items to review to help you meet all requirements successfully.
Review tax setup information
It is crucial to confirm that your tax setup is accurate and complete. We recommend that you go to Client Reports > Client Profile Report to validate company information:

- Name (or DBA name) should match the legal company name registered with tax agencies
- FEIN should match the legal FEIN registered with tax agencies
- Address should match the legal company address registered with tax agencies
Then, go to Reporting > My Reports and run the Tax List report.

Review the following items:
- Federal and state tax ID numbers
- State filing frequencies and rates

Important notes:
Please remember that tax agencies do NOT send any rate or filing frequency notices to Insperity, but they do send this information to you, the employer of record. If you have received these notices or see discrepancies in your isolved setup, please forward all information to your payroll specialist.
You must have a registered ID number with all appropriate state and federal agencies in order to file. Agencies do not accept “Applied For” ID numbers for filing and payments. Submitting your filings with an “Applied For” ID could cause delays and agency penalties and fees.
Review employee identification information
Go to Employee Management > Employee Summary and review employee names and Social Security numbers for accuracy.
