Learn how to calculate aggregate turnover for GST registration in India. Understand what counts, state-wise thresholds, and when you must register.
What Is Aggregate Turnover?
Aggregate turnover is the total value of all supplies you make in a financial year — excluding GST you've collected and returned goods. It's the single number that determines whether you must register for GST or can continue operating without it.
Understanding this is critical because:
• You might already be above the threshold without realizing it • Different states have different thresholds for services • Exceeding the limit even once can trigger mandatory registration from the next day
National vs. State-Wise Thresholds
India uses a two-tier threshold system:
For goods (all states): • Threshold: ₹40 lakh per financial year • You must register once this limit is crossed
For services: • Most states: ₹20 lakh per financial year • Special-category states (Assam, Himachal Pradesh, Uttarakhand, Jammu & Kashmir, Tripura): ₹10 lakh per financial year • States offer a ₹5 lakh exemption for startups and entities located in these regions
If your business spans multiple states, apply the ₹40 lakh (goods) or ₹20 lakh (services) national threshold — not state-by-state limits.
What Counts in Aggregate Turnover?
Include every rupee from:
• Sales of goods or services (your main revenue) • Rental income or lease payments • Job work charges (if you're processing someone else's raw materials) • Commissions or brokerage fees • Franchise fees or royalties • Interest earned on delayed payments • Gifts or grants to your business (treated as supplies in some cases)
Do NOT include: • GST collected (you pass this to the government) • Value of returned goods (if accepted by you) • Sales of capital assets (old machinery, furniture) — unless you deal in them • Inter-company transfers or internal restructuring
How to Calculate for Your Business
Step 1: List all revenue sources for the financial year (April to March).
Step 2: Add them up, excluding GST charged.
Step 3: Cross-check your bank statements and invoices to ensure accuracy.
Step 4: Compare against the relevant threshold (₹40 lakh for goods, ₹20 lakh or ₹10 lakh for services).
Example: A freelance consultant in Punjab earned ₹22 lakh from 5 clients. Threshold for services = ₹20 lakh. Mandatory registration required from day one of the next financial year.
Timing and Deadlines
Once you cross the threshold:
• You must apply for registration within 30 days of exceeding the limit • Registration takes effect from the day you cross the threshold (not from approval date) • Failure to register on time invites penalties of ₹10,000 or 10% of tax due — whichever is higher
If you're expecting to hit the threshold soon, register voluntarily. It positions you professionally and prevents last-minute compliance chaos.
