GST for MSMEs: the twelve decisions that matter

A smaller business cannot afford a tax department. It can afford twelve decisions taken properly.

The short answer

For a smaller business the exposure is concentrated in a few decisions: whether to register and when, whether to opt for composition, how to verify suppliers, how to reconcile credit monthly, how to handle e-way bills, how to answer a notice, and what to do when a registration is cancelled. Getting those right removes most of the risk without a tax function.

The first six decisions

One. Register when aggregate turnover crosses the threshold, computed on an all India basis including exempt supplies — not at the year end. And register immediately where Section 24 applies, including for any inter state supply of goods or any e-commerce channel.

Two. Composition or normal. Composition is simpler and cheaper for business to consumer trade with low input tax; it is wrong for business to business supply, because your customer gets no credit.

Three. Supplier verification. A dated GSTIN status extract and a bank payment for every material supplier. This single habit prevents most credit demands.

Four. Monthly reconciliation. Books against GSTR-2B against GSTR-3B, before filing. Ten minutes a month prevents a three year dispute.

Five. E-way bills from the invoicing system, with Part B before the vehicle leaves, and a printed roadside checklist for the driver.

Six. Portal monitoring. One named person checks the portal weekly. Almost every catastrophe in this sector begins with a notice nobody saw.

The next six

Seven. Never ignore a notice, including ASMT-10 and DRC-01A. Answer it in writing on the portal within the time stated, with documents.

Eight. Pay what is genuinely payable under Section 73(5) before a notice; it eliminates penalty.

Nine. Never make a payment during a search or an inspection without a letter recording that it is under protest.

Ten. Diarise the two dates that lose money: 30 November for credit and credit notes, and three months from an order for an appeal.

Eleven. If the registration is cancelled, apply for revocation within thirty days, with the returns filed and dues paid.

Twelve. Keep the records for six years, including monthly downloads of GSTR-2B and the ledgers, because the audit arrives late.

What not to spend money on

Elaborate advisory on positions that do not affect you. Most MSME exposure is procedural, not interpretive.

Litigating a small genuine liability. Pay it, take the Section 73(5) benefit, and move on.

Multiple registrations you do not need. Each one carries returns, audits and cancellation risk.

What is worth paying for is a one page annual review of these twelve decisions, and counsel at the first notice rather than the third.

What to do on Monday

  1. Compute aggregate turnover monthly and register at the threshold, not at the year end.

  2. Take a dated GSTIN extract and pay through banking channels for every material supplier.

  3. Reconcile books, GSTR-2B and GSTR-3B before filing, every month.

  4. Assign one person to check the portal weekly and to diarise 30 November and appeal dates.

Questions we are asked on this

Should we opt for composition?

Only for business to consumer trade with low input tax. For business to business supply it makes you uncompetitive because your customer gets no credit.

Do we need registration to sell online?

Registration is compulsory for most sellers supplying through a platform required to collect tax at source.

What is the single most valuable habit?

The monthly GSTR-2B to books reconciliation, and the dated supplier GSTIN extract.

What if we cannot afford an appeal pre-deposit?

Check whether a rectification reduces the demand, and take advice on the writ route where the order is jurisdictionally defective.

How long must records be kept?

Seventy two months from the annual return due date, and longer for a contested year.
