Built with a CA firm, for CA firms.
Kosh makes software for Indian Chartered Accountant firms. Our first product is TACT, which runs a Section 44AB tax audit from acceptance to a locked file.
Sharma Industries
3CD Audit · FY 2025-26
Form 3CD has 44 clauses, and a firm works through them for many clients in the same few weeks each year. The work ends up spread across spreadsheets, email and shared folders, and that leaves one question hard to answer later.
Who checked this, and when?
TACT puts each clause, its work programme and its sign-offs in one place, and keeps the papers in the firm’s own SharePoint.
