MEZAccountax provides professional research and development tax credit services to startups, entrepreneurs, and other U.S. businesses. The company helps clients identify qualifying innovation activities, calculate potential credits, prepare claims, and assemble documentation designed to support compliance with IRS requirements. Its guidance covers eligibility, qualified expenses, and the records needed for a claim, including payroll details, expense ledgers, project notes, prototypes, test results, and contracts for outside research.

The service focuses on work to develop or improve products, processes, software, and other technical solutions through experimentation to resolve uncertainty. Potentially eligible costs may include employee wages, research supplies, certain computer rental or cloud expenses, and contract research. MEZAccountax also offers a calculator to estimate credits using the Alternative Simplified Credit method, a free application and consultation, and support with retroactive claims for eligible businesses. Clients can choose fee arrangements based on cash flow, including upfront, contingency, or deferred fees, subject to a retainer. Tax preparers can also contact the company about referral partnerships.
