What MasterTax is

MasterTax is cloud-based payroll tax software for businesses and payroll providers managing federal, state, and local tax obligations. From one dashboard, users can import payroll data, schedule payments, prepare returns, and manage reporting across more than 11,000 U.S. payroll tax jurisdictions. The software creates original and amended returns, along with agency-specific payment coupons and vouchers, in paper, e-file, and removable media formats. Its workflows also cover agency notices, customizable reports, and payment scheduling. MasterTax says it integrates with most payroll systems and offers APIs for importing files, retrieving files, and sending data extracts to external systems.

Optional modules include Tax Locator, Wage Attachment, New Hire Reporting, Cash Care, and Bank Reconciliation. New Hire Reporting supports all 50 states through fax, e-file, or secure FTP. A dedicated implementation specialist assists with discovery, migration, configuration, and setup. After launch, customers can reach support by email or phone, submit tickets, and use a client portal with 24-hour access to materials and updates. Payroll service providers can also use a nonproduction environment for scenarios, payment workflows, and employee training. MasterTax is based in Tempe, Arizona, and says it operates independently after its 2010 acquisition by ADP.
