TaxSaaS

Automated sales tax compliance for SaaS businesses.

● The Problem

SaaS companies owe sales tax in every state where they have customers (economic nexus). Most founders ignore this until they get a notice. Avalara and TaxJar are enterprise-priced. The compliance burden falls hardest on small businesses.

● The Solution

A Stripe integration that automatically calculates, collects, and files sales tax for digital products. Monitors your nexus obligations, applies correct tax rates, and generates filing-ready reports.

Competitive Landscape

Avalara ($200+/mo) and TaxJar (acquired by Stripe but still expensive) dominate. Stripe Tax exists but lacks filing. An affordable, SaaS-specific solution with filing support is the gap.

Why Now?

More states are enforcing digital product tax collection. Stripe Tax handles calculation but not filing. The compliance gap between calculation and filing is where the pain is.
