Applying contrarian thinking to taxes

We provide tax professionals with the tools they need to build a successful tax firm, and we help individuals and businesses make better financial decisions and achieve the best tax outcomes.

Portrait of ZipperTax Founder, Jack Mao

I dropped out of Stanford, where I studied Computer Science, to build ZipperTax after becoming increasingly frustrated with the inefficiencies I faced as a tax professional of 5 years and the amount of tax savings people missed out on (upwards of $60,000+) because they weren't tax efficient. ZipperTax is built for every American who values their time and money.
