GST 2.0, Rising Food Inflation, and What It Means for Your FY27 Compliance Calendar

Two macro threads are worth tracking together if you run a small or growing business in India right now: the GST 2.0 rate rationalisation that took effect in September 2025, and a steady, monthly climb in retail inflation through the first half of 2026.

GST got simpler, but your product mix may have moved tax slabs

The GST Council’s 2.0 reform collapsed the old multi-slab structure (0%, 5%, 12%, 18%, 28%, plus cess complications) into essentially two main slabs, 5% and 18%, with a 40% slab reserved for luxury and “sin” goods, and a couple of niche residual rates surviving for specific items. Several everyday categories moved down: household items like soap, shampoo, and toothpaste shifted from 18% to 5%, and a number of essential goods and medicines moved to nil-rated. If you sell, manufacture, or distribute physical goods, it’s worth re-checking your full product catalogue against the new slab list rather than assuming your old classifications still hold. A product that moved slabs affects your pricing, your input tax credit math, and potentially your invoicing templates.

Inflation has been creeping up every month this year

Headline retail inflation (CPI) has risen in each of the first five months of 2026, from roughly 2.75% in January to just under 4% by May, and food inflation has run noticeably hotter than the headline number. Rural inflation has already crossed the RBI’s 4% medium-term target, even though the national average hasn’t quite breached it. For a business, this shows up less as a single dramatic event and more as steady upward pressure on raw material costs, logistics, and wages, the kind of drift that’s easy to under-budget for if you’re still working off last year’s cost assumptions.

Practical takeaways for FY27 budgeting

• Re-run your product/input GST classification against the 2.0 slab list. Don’t assume nothing changed just because your business wasn’t directly in the headlines about the reform.
• Build a modestly higher input-cost inflation assumption into FY27 budgets than you used last year, particularly for raw materials and logistics-heavy categories.
• If your business runs a Global Capability Centre or is evaluating one, the Budget 2026 transfer pricing safe harbour (broadly around 15.5%) is worth a specific conversation with your advisor. It changes the documentation and pricing conversation for a large number of existing and new GCC units.
• Keep your compliance calendar (GST returns, advance tax instalments, ROC filings) reviewed against current rates rather than relying on muscle memory from FY26.

Individually, none of these are dramatic shifts. Together, they’re the kind of quiet, compounding changes that show up in margins six months later if nobody is specifically watching them.
