What MasterTax does
MasterTax, LLC is a Scottsdale/Tempe, Arizona-based software vendor that builds cloud-based payroll tax filing and compliance technology for U.S. employers operating across multiple jurisdictions. The company's core product automates the end-to-end payroll tax workflow — scheduling payments based on agency mandates, creating returns and vouchers, balancing deposits against liabilities, and filing electronically — with built-in compliance coverage for more than 11,000 federal, state, and local jurisdictions, supported by an internal team that monitors legislative and regulatory changes. Around this core, MasterTax offers add-on modules including a Tax Locator Tool (local code/rate identification), Wage Attachment Tool (garnishments), New Hire Reporting (all 50 states via fax, e-file, or secure FTP), Cash Care (NACHA-formatted ACH disbursement), Bank Reconciliation, an Agency Notice Manager, and a Nonproduction Testing Environment, plus three APIs (File Import, File Retrieval, Data Extract) for integration with payroll, HR, and ERP systems.
The platform is sold primarily on a quote-based subscription model targeting three customer segments: individual companies with multi-jurisdictional payroll complexity (small employers to large corporations with 30 to 300,000 employees), third-party payroll service providers, and professional employer organizations (PEOs). Distribution is through an enterprise field sales motion (dedicated phone line, 'Speak to Sales' form) supplemented by a partner referral program for ERP and software providers. MasterTax was acquired by ADP in 2010 and continues to operate as a separate and independent subsidiary, leveraging ADP's enterprise reach while maintaining its specialized payroll tax compliance focus and brand.
