ModernTax is the tax infrastructure for the fintech economy.

About Us

Tax records are in a black box. As more consumers move to online financial services, banks, lenders, mortgage underwriters, and insurers lack real-time access to their tax records. Consumers have no way to instantly allow their tax records to be used for faster, more efficient financial services. This is where ModernTax comes in.

ModernTax is the tax infrastructure for the fintech economy. We enable consumers to access their tax information and share it with the financial services ecosystem. This provides digital finance companies the ability to build embedded tax products within their native experiences. Our API layer is built on top of IRS infrastructure and provides a consumer-permissioned access point to read and write functions such as instantly verifying historical tax records, income and identity. ModernTax is democratizing access to every form of consumer and business tax data to enable a bevy of growing applications and use cases.

Today, we're growing fast and excited for new teammates to join us who are the best at what they do. We're passionate about building a company that represents diversity, inclusion, and a shared commitment to our mission.
