Eight months in, what GST 2.0 actually did to small-business pricing

When the GST Council announced the move to a three-slab structure last September — 5%, 18% and a 40% “sin and luxury” band — most of the WhatsApp commentary was about how clean it would be. Eight months in, the cleanness is real for the consumer. For the MSME owner sending out 200 invoices a month, the picture is more mixed.

What the rate move actually did

The 22 September 2025 notification collapsed the old 12% slab into either 5% or 18% depending on the item, and moved a small luxury basket to the new 40% band. The much-feared end-consumer price shock did not materialise, mostly because the items that moved down were the everyday ones (packaged staples, school supplies, generic medicines) and the items that moved up were the ones people buy occasionally.

That much was predicted. What was not predicted, at least not in the news cycle, was the input-credit cliff for businesses that sit at the boundary.

The boundary problem nobody warned about

If you sell a product that moved from 12% to 5%, your output liability halved overnight. Wonderful. But the raw materials you used to make that product? Some of those stayed at 18%. Now your accumulated input tax credit grows faster than you can absorb it.

For larger units this is a refund claim. For an MSME with patchy filing history, it is a refund claim that takes months and ties up working capital while it waits.

The three sectors I have seen this hit hardest:

• Local FMCG packers — output at 5%, packaging material at 18%, freight at 5%. The maths only works at scale.
• Education-content publishers — printed material moved to 5% but the digital licensing layer stayed at 18%. Mixed-supply invoices are now a minefield.
• Restaurants that took the composition route — nothing changed for them on output, but their suppliers' rate changes are now flowing through.

The billing software is the slow part

Every accounting platform I work with rolled out an “auto-remap” tool by October. They all do roughly the same thing — scan your item master, suggest the new HSN-to-rate mapping, ask you to confirm. The trouble is what they cannot do automatically:

Old purchase invoices, already booked at the old rate, that come back as credit notes after 22 September. Your software does not know whether to honour them at the old rate or the new one. The answer is the old rate — the rate is fixed as of the date of the original supply — but most platforms will let you cheerfully book it wrong.

I have had to manually adjust credit-note rates in three client files this quarter. None of the clients had done anything wrong; their software just defaulted to today's rate.

What to actually check on your June books

1. Reconcile your output rate against GSTR-1 line by line for September and October 2025. The cut-over month is where mismatches hide.
2. Check GSTR-2B against your purchase register for the same months. Vendor side errors are common.
3. If you have accumulated ITC, file the refund claim now. The eight-month window from the date of accumulation is shorter than it sounds.
4. Update your e-invoice item master. Several clients still have a few legacy SKUs sitting on the old 12% rate, which is a cancellation-and-reissue waiting to happen.

Was the rationalisation worth it?

For the end consumer, yes. The 5% slab is closer to a real consumption tax now, and the everyday basket is genuinely cheaper. For the MSME middle — the businesses that file every quarter, that do not have a CFO, that learned the old rate table by heart — this is still a tax compliance year. The pricing benefit will come. The bookkeeping cost is now.

The Council's job was structural. The work of moving the structure through 80 lakh MSME books falls on us. Eight months in, we are perhaps halfway there.
