These calculators give quick, educational estimates based on rules in effect as
of September 2026 - they are not tax advice and don't account for every
exception (surcharge, marginal relief, indexation edge-cases, etc.). For your
actual filing, please talk to a Compdesk expert.
Business Registration & Compliance Starter Checklist
A free, practical checklist covering business registration, GST, ROC annual compliance and income tax deadlines for Indian startups & small businesses.
Why not just file it yourself?
These calculators give you a solid estimate - but tax law has exceptions, and getting it wrong costs more than getting it filed right. Compdesk's experts double-check every number before it goes to the department.
