Every state. Every law. Always current.

Tax software is fragmented. TurboTax doesn't talk to Drake. H&R Block doesn't sync with the IRS in real-time. TaxNexus connects them all into one compliance layer that never falls behind.

The Problem

Tax professionals juggle five tools that don't talk to each other.

Siloed platforms

TurboTax, H&R Block, Drake Tax, ProConnect. Each one a walled garden. Moving data between them means manual exports, reformatting, and hoping nothing breaks.

Laws change constantly

Thousands of state and federal tax law updates every year. Most software lags weeks behind. One missed update means a compliance violation or an incorrect filing.

IRS systems are disconnected

The IRS is modernizing its APIs, but no commercial platform connects in real-time. Tax pros are still downloading PDFs and cross-referencing manually.

Multi-state is a nightmare

Economic nexus thresholds differ by state. Filing requirements change by jurisdiction. Managing compliance across all 50 states takes armies of accountants.

The Solution

One integration layer for the entire tax ecosystem.

🔗

Universal Connector

Plug into TurboTax, H&R Block, Drake, ProConnect, and more. One API that reads from and writes to every major platform.

Real-Time Law Sync

Automatically tracks tax law changes across all 50 states and federal regulations. Alerts you the moment something shifts.

🏛

IRS Direct Link

Connects to IRS systems as APIs become available. No more manual lookups. Compliance data flows directly into your workflow.

Tax compliance shouldn't require five logins and a prayer.

TaxNexus is building the connective tissue the tax industry has needed for decades. One platform. Every jurisdiction. Always current.
