What is GST and why should a pet business care?
GST (Goods and Services Tax) is one tax that replaced the old mix of VAT, service tax and excise. Every product you sell and every service you offer has a GST rate attached. When you buy stock - food, shampoo, collars, medicines - you pay GST to your supplier. When you sell, you collect GST from the customer.
The part most small pet businesses miss: if you're GST-registered, the GST you paid on purchases comes back to you as credit. If you're not registered, it's just a cost. That one difference changes your margins, and it's what this calculator is built to show.
Registered or not: what changes for your business
GST-registered
- You charge GST on every sale (grooming, boarding, products)
- You claim back the GST you paid on stock and supplies (Input Tax Credit)
- You pay the government only the difference: GST collected minus GST paid
- You can sell to other businesses, on marketplaces, and across states
- You file monthly or quarterly returns
Not registered
- You cannot charge GST on sales
- The GST you pay on stock is a cost you absorb - no credit
- You keep the full amount the customer pays
- You can't sell inter-state or on most marketplaces
- No GST returns to file
Registration is mandatory once your turnover crosses ₹40 lakh for goods or ₹20 lakh for services in most states (lower in some north-eastern and hill states), or immediately if you sell inter-state or through an online marketplace. Confirm with your CA.
GST slabs in India for 2026 (in force since 22 September 2025)
The old five slabs (0, 5, 12, 18, 28%) were replaced by four. Here's where pet-industry items land:
0%
Exempt
Vet consultation by a registered vet, cattle/poultry feed
5%
Everyday
Pet shampoo, vet medicines, vaccines, pet toys, diagnostic kits
18%
Standard
Pet food, collars, leashes, bowls, crates, grooming, boarding, daycare
40%
Luxury & sin
Not applicable to typical pet businesses
Note: Pet food (HSN 2309) is taxed at 18% even though cattle and poultry feed is exempt - a common point of confusion.
Pet-industry GST rates for 2026, and what they replaced
These are the rates in force today. The previous column is the regime that ran until 21 September 2025 - four pet-industry lines came down, the rest held.
| Item | HSN / SAC | Before 22 Sep 2025 | Rate now (2026) | What it means for you |
|---|---|---|---|---|
| Pet food (dog, cat) | 2309 | 18% | 18% | No change |
| Pet shampoo & grooming products | 3305 | 5% | Cheaper to stock | |
| Veterinary medicines | 3003 / 3004 | 5% | Cheaper for clinics | |
| Vaccines | 3002 | 5% | 5% | No change |
| Pet toys | 9503 | 5% | Cheaper to stock | |
| Collars, leashes, harnesses | 4201 | 18% | 18% | No change |
| Bowls, crates, carriers | 3924 / 3926 | 18% | 18% | No change |
| Diagnostic kits | 3822 | 5% | Cheaper for clinics | |
| Grooming services | 9997 | 18% | 18% | No change |
| Boarding & daycare | 9997 | 18% | 18% | No change |
| Vet consultation (registered vet) | 9983 | Exempt | Exempt | No change |
Rates as notified by CBIC effective 22 September 2025 and unchanged since - there is no separate 2026 revision. Classification can vary by product (e.g. medicated vs cosmetic shampoo). Check the HSN on your supplier invoice and confirm with your CA.
What the 2026 rates are worth to you, in rupees
Rate tables are abstract until you put an order behind them. Below is the same ₹10,000 of stock (before GST) bought under the old rate and today's rate.
| Item | Rate change | You used to pay | You pay now | Cash saved per order |
|---|---|---|---|---|
| Pet shampoo & grooming products | 18% → 5% | ₹11,800 | ₹10,500 | ₹1,300 |
| Veterinary medicines | 12% → 5% | ₹11,200 | ₹10,500 | ₹700 |
| Pet toys | 12% → 5% | ₹11,200 | ₹10,500 | ₹700 |
| Diagnostic kits | 12% → 5% | ₹11,200 | ₹10,500 | ₹700 |
| One order of each, ₹10,000 apiece | ₹3,400 | |||
If you're registered
You were always getting that GST back as input tax credit, so the cut doesn't change your profit on a sale. What it changes is cash flow: ₹3,400 less is parked with the government waiting to be set off. Buying at 5% while selling grooming at 18% means more net GST each month, not less - the credit side just got smaller.
If you're not registered
This is a straight cost saving. You never could claim that GST back, so ₹3,400 less leaving the business is ₹3,400 more profit on the same shelf price. Put your own numbers in the calculator to see where you now land.
CGST, SGST and IGST - which one shows up on your bill?
CGST + SGST (same-state sales)
When you sell within your state, the GST splits in half: one half to the Centre, one half to the State. A ₹1,000 grooming session at 18% shows ₹90 CGST + ₹90 SGST.
IGST (inter-state sales)
When you sell to another state - say a Bengaluru store shipping to Chennai - the full rate goes as IGST. Same ₹1,000 at 18% shows ₹180 IGST.
Does it change what you pay?
No. The total is identical. It only changes how the invoice is labelled. Your billing software should handle this automatically.
The two formulas behind every GST calculation
Adding GST (you know the base price)
GST amount = Base price × Rate ÷ 100
Total = Base price + GST amount
Example
Grooming session priced at ₹1,000 base, 18% GST
GST = 1,000 × 18 ÷ 100 = ₹180
Customer pays = ₹1,180
Removing GST (you know the price the customer paid)
Base price = Total × 100 ÷ (100 + Rate)
GST amount = Total − Base price
Example
A 3 kg bag of dog food sold at ₹1,180 (GST included), 18%
Base = 1,180 × 100 ÷ 118 = ₹1,000
GST = 1,180 − 1,000 = ₹180
How to use this calculator
- 1
Tell us if you're GST-registered.
This decides whether input tax credit applies.
- 2
Enter what you paid and what you sell for.
The purchase price is treated as the base price before GST, the way supplier invoices quote it - tick “includes GST” if your figure already has tax in it. The sale price is treated as GST-inclusive, since that's what the customer pays.
- 3
Read your results.
Profit, margin, GST paid, GST collected, credit you can claim and what you owe - in one panel.

Frequently Asked Questions
Registration becomes mandatory once turnover crosses ₹40 lakh for goods or ₹20 lakh for services in most states (₹20 lakh / ₹10 lakh in some special-category states). It's mandatory from day one if you sell inter-state or through an online marketplace, regardless of turnover. Many businesses register voluntarily below the threshold to claim input tax credit and sell to other businesses.
