Payroll Tax Filing

Payroll Tax Filing

Payroll tax filing is the filing of employment tax returns such as quarterly 941s, state DE9/9C, and annual W2s. This service is also known as After-the-Fact Payroll tax filing, Furthermore, it mostly applies to CPA firms and payroll professionals who use calculation methods or software which does not have filing capabilities. 

When AccuPay launched under CCH in the 1980s, payroll tax filing was the only service we offered. As a result, our only client base was CPA firms and small payroll bureaus.

If you process payroll in-house and need to file payroll taxes, we would love to help. We file all the necessary quarterly and annual returns. We also process 1099s and 1098s. If you would like to switch to full service payroll which includes tax filing, call us at 949-202-0078 for more information.
