Business Registrations in India: The Complete PAN, GST, MSME & IEC Checklist (2026)

Skip your registrations now, and you'll pay for it during your first fundraise or your first big customer contract.

Business registrations in India aren't bureaucratic paperwork — they're infrastructure. PAN, GST, MSME, IEC, and Shop & Establishment each unlock something specific: tax compliance, government scheme eligibility, faster payment protection, or the ability to operate legally in a given state. This guide covers every registration that actually matters, when each one is required, and what happens if you skip them.

The complete registration roadmap

• PAN (Permanent Account Number). Required for every company from day one — every financial transaction, bank account, and tax filing depends on it.

• TAN (Tax Deduction and Collection Account Number). Required as soon as the company deducts TDS on any payment — salaries, rent, professional fees. Apply alongside PAN if you'll have employees or vendors from the start.

• GST Registration. Mandatory once turnover crosses ₹20 lakh (₹10 lakh in special category states) for services, or ₹40 lakh for goods in most states. Required immediately, regardless of turnover, for inter-state supply or e-commerce sellers.

• MSME / Udyam Registration. Free, fast, and worth doing on day one regardless of size. Unlocks priority lending, government tender eligibility, and — critically — the 45-day payment protection under the MSMED Act, which legally obligates larger buyers to pay MSME-registered vendors within 45 days.

• IEC (Import Export Code). Required before any company's first international transaction — exporting goods or services, or importing. A 1-2 day online process through DGFT, but easy to forget until a deal is already in motion.

• Shop & Establishment Registration. State-specific, usually required within 30 days of starting operations at a physical location. Often the most overlooked registration for digital-first startups operating from a co-working space or office.

• Professional Tax Registration. State-specific, relevant once the company has employees — applicable rates and thresholds vary significantly by state.

• Industry-specific licenses. FSSAI for food businesses, drug licenses for pharma, NBFC registration for lending — required based on sector, often before operations can legally begin.

What happens when these get skipped

• GST registration delayed past the turnover threshold — penalties plus interest on unpaid tax, and the inability to claim input tax credit retroactively

• MSME registration skipped — losing the 45-day payment protection, meaning larger buyers can legally delay payment far longer, directly hurting cash flow

• IEC missed before a first export — the transaction stalls at customs while the registration is rushed through, costing days or weeks of delay

• Shop & Establishment ignored — fines during a labour department inspection, which also surfaces during investor due diligence as a compliance gap

Why this matters beyond legal compliance

The right registrations don't just keep a business legal — they unlock tax benefits, government scheme eligibility, and investor confidence. A clean registration trail is one of the items investors check early in due diligence; gaps here read as operational immaturity even in an otherwise strong business. For B2B businesses specifically, many larger customers and government tenders require a valid GST number and MSME registration before they'll even issue a purchase order.

Getting the sequence right

Most founders don't get the order wrong on purpose — they simply don't know one registration depends on another. A practical sequence:

• PAN and TAN immediately after incorporation

• MSME/Udyam registration in the same week — it's free and fast, no reason to delay

• Bank account opening, which requires PAN and incorporation documents

• GST registration before crossing the threshold, not after

• Shop & Establishment within 30 days of starting operations at a physical address

• IEC before the first cross-border transaction is even negotiated, not after a deal is signed
