The 2026 Festive Calendar
Onam through to Bhai Dooj with the dates that matter, plus a buying clock that works backwards from Diwali on 8 November.
An 11-page guide to planning the 2026 festive season, working backwards from Diwali on 8 November. The buying clock, the ₹2,500 GST rate line that decides 5% or 18% per garment, the markdown ladder, supplier credit notes, and returns. Every rule cited with its section or notification number.
Onam through to Bhai Dooj with the dates that matter, plus a buying clock that works backwards from Diwali on 8 November.
Why apparel is 5% at or below ₹2,500 per piece and 18% above, why it is tested per garment and not per bill, and what changed on 22 September 2025.
How Section 15(1) and 15(3)(a) mean the rate is tested on the discounted price, with a worked example on a ₹2,999 kurta.
Sell-through, size curves, carry-forward and realised margin, computed from your own last-season numbers rather than someone else's benchmark.
A five-step ladder timed to Navratri, Dussehra and Diwali, so each cut is smaller and earlier instead of deep and late.
The difference between a GST credit note and a financial credit note, when you must reverse input tax credit, and how to handle festive exchanges.
Petpooja Invoice applies the right GST rate to each garment from its billed value, records on-invoice discounts the way Section 15(3)(a) requires, and gives you item-wise and size-wise sales through the peak so the reorder decision is made on data.
Explore Petpooja InvoiceDiwali falls on 8 November 2026. That is late, and it moves every other date with it. The buying decisions that determine how the season goes are being made right now, in August, months before a single festive garment is sold.
There is also a number that changed under most retailers’ feet. On 22 September 2025 apparel GST was restructured. The 12% slab was abolished. A garment is now taxed at 5% if its sale value is up to ₹2,500 a piece, and 18% above that. The change took effect on 22 September 2025, and it applies per piece, not per bill.
That distinction is being got wrong at counters. Four kurtas at ₹900 each is four items at 5%. It is not one ₹3,600 sale at 18%. A customer who is overcharged on a festive bill tends to photograph it.
The more interesting consequence is what happens when you discount. Section 15(1) of the CGST Act sets the value of a supply as the transaction value, the price actually paid. Section 15(3)(a) then excludes a discount from that value where it is given at or before the time of supply and recorded on the invoice. So the ₹2,500 test is applied to the discounted price, not to the tag.
A kurta tagged ₹2,999, discounted 20% on the bill to ₹2,399, is taxed at 5% rather than 18%. If your festive range is priced between ₹2,600 and ₹2,900, you are sitting just the wrong side of a rate boundary and paying 18% on all of it. That is a pricing decision worth making deliberately in August, not discovering in your GST returns in December.
None of this helps if the billing system decides the rate from the tag price instead of the billed value, or if discounts are handed over off the bill. Both are common, and both quietly cost margin for eight weeks. It is the sort of thing that separates proper billing software from manual billing when volumes triple.
This guide works backwards from 8 November: when to close the buy, how to build a markdown ladder around Dussehra and Diwali, how supplier credit notes affect your input tax credit, and how to handle the wave of exchanges that arrives after the festival. Every rule carries its section or notification number so you can check it at CBIC yourself.
Here's a preview of what you'll get inside:
The rate line. A garment sold at or below this is taxed at 5%. Above it, 18%. Tested on each piece separately, never on the invoice total.

Source: Standard panchang references, read 03-Aug-2026The 12% slab was abolished on 22 September 2025. Garments that sat there moved either down to 5% or up to 18%, depending purely on whether they cross ₹2,500.
Source: Press Information Bureau, GST Reforms 2025, dated 04-Sep-2025Four kurtas at ₹900 each are four items at 5%, not one ₹3,600 supply at 18%. The ₹2,500 test is applied per piece. Over-collecting on a festive bill is the kind of error customers photograph and share.
Section 15(1) values a supply at the price actually paid. Ring up a ₹2,999 item with a 20% discount and check the bill. If it charges 18% rather than 5%, your system is testing the wrong number. Worth checking against your billing software options.
A discount reduces taxable value only if it is given at or before supply and recorded on the invoice, under Section 15(3)(a). A cash reduction outside the bill means you collected less and still owe GST on the higher value.
This band sits just above the rate line and attracts 18%. A modest planned on-invoice discount moves it to 5%. Decide that in August rather than finding it in the return.
Holding nothing back means you cannot chase whatever turns out to be selling in October. Agree the reorder terms with your main suppliers before the season, not during the peak.
Demand peaks in the days before 8 November. Cutting price then gives away margin on stock that had buyers at full price. Plan the ladder so cuts land in late October and after 12 November.
A GST credit note under Section 34 reduces your taxable value and requires you to reverse input tax credit. A financial credit note does neither. CBIC clarified this in Circular 251/08/2025-GST dated 12 September 2025. Ask in writing in September, not in December across a dozen suppliers.
