Our story
Why we started Cosomtax
Cosomtax began with a simple observation: growing businesses spend too much time chasing compliance deadlines and too little time growing. Owners juggle a tax consultant, an auditor and a software vendor who rarely talk to each other.
We set out to be one dependable partner for all three. Our compliance team handles GST, income tax, company registration and audit support, while our technology division builds web applications, mobile apps and ERP tools. Because both teams sit together, the software we build understands invoices, credit, deductions and reporting, and our advisors understand the systems your data comes from.
From our office in Guduvanchery, Chennai, we work with startups, professionals and established businesses across Tamil Nadu and beyond, mostly through a paperless process.
