Remitian has raised $7m in seed funding and launched a tax payment application programming interface (API) aimed at tax software providers and accounting practices.

Headquartered in Miami, Florida, US, the company provides an AI-powered remittance engine to automate how businesses collect, pay and reconcile taxes.

In a statement, Remitian said that the new API is designed to address the “final mile” of tax payments.

The API lets partners embed payment initiation, validation and confirmation within their existing platforms. It acts as a unified access point for multiple tax authorities, removing the need for manual entries in bank portals.

By routing payments through a single gateway, Remitian said it also aims to reduce errors that can lead to penalties.

Remitian CEO Solon Angel said: “The journey from ‘Ready to File’ to ‘Ready to Pay’ has historically been a broken, manual process.

“Our new API allows our partners to streamline the entire tax payment experience, providing real-time updates via webhooks and bank-grade audit logs to ensure every payment is tracked from start to finish.”

The company’s funding round saw participation from a group of accounting and fintech executives including Ryan Lazanis, Aprio CEO Richard Kopelman and Koho CEO Daniel Eberhard.

The round has also seen participation from Cambrian founding partner Rex Salisbury, and the chief executives of HubSync and Aiwyn.

Remitian said the capital will be used to grow its network of North American partners.

Targeted partners include accounting practices, wealth management firms and global financial institutions.

Angel added: “Our team has spent more than a decade building AI products for accountants.

“We are bringing that experience to the tax payment layer so firms can move money compliantly, reconcile faster and serve clients with confidence. We want firms to be able to focus on their bottom line, not tax deadlines.”
