What is the GST threshold for service providers?

Service providers must register for GST if their aggregate annual turnover exceeds ₹20 lakh in normal states or ₹10 lakh in special category states. If a business supplies both goods and services, the lower threshold (services threshold) applies. Aggregate turnover includes all taxable, exempt, export, and inter-state supplies on a PAN-India basis.

Who must register for GST regardless of turnover?

Under Section 24 of the CGST Act, certain persons must register for GST irrespective of turnover. These include: persons making inter-state taxable supplies, casual taxable persons, non-resident taxable persons, those liable to pay tax under reverse charge, e-commerce operators and sellers on e-commerce platforms, TDS deductors, input service distributors, and agents supplying on behalf of others.

What is the penalty for not registering for GST when required?

Under Section 122 of the CGST Act, if a person who is required to register for GST fails to do so, they face a penalty of 100% of the tax due or ₹10,000, whichever is higher. In cases of deliberate tax evasion, prosecution proceedings can also be initiated under Section 132. Additionally, the person cannot claim input tax credit for the period they were unregistered.

Should I register for GST voluntarily even if below threshold?

Voluntary GST registration below the threshold can be beneficial if: (1) You sell to B2B customers who need your GSTIN to claim input tax credit. (2) Your GST-bearing purchases are significant and you want to claim ITC. (3) You plan to make inter-state sales. However, voluntary registration means mandatory compliance — filing GSTR-1 and GSTR-3B regularly. For B2C businesses with low purchases, the compliance cost may outweigh the ITC benefit. Registration is irrevocable for 1 year.

Q: What is the GST registration threshold for goods in India?

For suppliers of goods in normal category states, the GST registration threshold is ₹40 lakh aggregate annual turnover. In special category states (Arunachal Pradesh, Assam, Himachal Pradesh, Jammu & Kashmir, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, Uttarakhand), the threshold is ₹20 lakh. These thresholds were set by Notification No. 10/2019-Central Tax and remain unchanged for FY 2025-26.

Check if your business needs GST registration based on turnover, state, and business type. Track your proximity to the threshold, understand mandatory registration categories under Section 24, and evaluate whether voluntary registration is worth it for ITC claims. Updated for FY 2025-26.

How to Use This Calculator

Do I Need GST? tab

Select your business type (goods, services, or both), your state, and enter your annual aggregate turnover. The calculator instantly tells you whether GST registration is required, the applicable threshold for your state, and your margin to the threshold. It also checks for mandatory registration triggers like inter-state supply and e-commerce selling.

Threshold Tracker tab

Enter your average monthly turnover to project when you will cross the GST threshold during the financial year. The calculator estimates your cumulative annual turnover, shows the remaining margin, and tells you the month you are likely to cross the threshold. This helps you prepare for registration before the deadline.

Voluntary Registration tab

If you are below the threshold, should you still register? Enter your annual purchases with GST and customer type (B2B or B2C). The calculator estimates your Input Tax Credit (ITC) recovery, compliance costs, and gives a net benefit recommendation. B2B sellers especially benefit from voluntary registration as their customers need GSTIN invoices to claim their own ITC.

The Formula

GST Registration Required = Aggregate Turnover > Threshold

Threshold (Normal States):
Goods: &rupee;40,00,000 (₹40 lakh)
Services: &rupee;20,00,000 (₹20 lakh)

Threshold (Special Category States):
Goods: &rupee;20,00,000 (₹20 lakh)
Services: &rupee;10,00,000 (₹10 lakh)

Aggregate Turnover =
Taxable supplies + Exempt supplies + Exports + Inter-state supplies
(Excludes: Inward supplies under reverse charge, CGST/SGST/IGST/cess)
Calculated on PAN-India basis (all businesses under same PAN)

Mandatory Registration (Section 24):
Required regardless of turnover for inter-state supply, e-commerce sellers, casual taxable persons, NRI taxable persons, reverse charge payers, TDS deductors, input service distributors, and agents.

Voluntary Registration Benefit:
Net Benefit = ITC Recoverable − Annual Compliance Cost

Worked Example

Priya — freelance designer in Maharashtra approaching ₹20L threshold

Priya (28) is a freelance UI/UX designer in Mumbai. She provides services only within Maharashtra. Her monthly billing has been growing steadily.

Step 1: Determine threshold

Business typeServices

StateMaharashtra (normal category)

Applicable threshold&rupee;20,00,000

Step 2: Calculate aggregate turnover

Average monthly billing&rupee;1,80,000

Projected annual turnover&rupee;1,80,000 × 12 = &rupee;21,60,000

Exceeds threshold by&rupee;1,60,000

Step 3: When will she cross?

Months to reach ₹20L&rupee;20,00,000 ÷ &rupee;1,80,000 = 11.1 months

Crossing monthFebruary (month 11 of FY)

Step 4: Voluntary registration analysis

Annual purchases with GST&rupee;3,00,000 (software, equipment, hosting)

ITC recoverable (at 18%)&rupee;54,000/year

Compliance cost&rupee;24,000/year (CA fees + filing)

Net benefit&rupee;30,000/year

Verdict: Priya will cross the threshold by February. Since she also has significant GST-bearing purchases and her clients are B2B (startups who need GSTIN invoices), she should register now rather than wait. The ITC benefit alone is ₹54,000/year, and B2B clients prefer GST-registered vendors.

FAQ

How is aggregate turnover calculated for GST registration? ▼

Aggregate turnover includes the value of all taxable supplies, exempt supplies, exports, and inter-state supplies made by persons with the same PAN across India. It is calculated on a PAN-India basis, not state-wise. It excludes the value of inward supplies under reverse charge and the taxes (CGST, SGST, IGST, Cess) themselves. For a person with multiple businesses under one PAN, all turnover is combined. For example, if you have a goods business earning ₹25L and a consulting service earning ₹10L under the same PAN, your aggregate turnover is ₹35L.

Can I register for GST voluntarily even if my turnover is below the threshold? ▼

Yes. Under Section 25(3) of the CGST Act, any person can voluntarily register for GST even if their turnover is below the threshold. Benefits include: ability to claim Input Tax Credit (ITC) on purchases, ability to make inter-state sales, and credibility with B2B customers who need GSTIN invoices. However, once registered voluntarily, you must comply with all GST filing requirements (GSTR-1, GSTR-3B) and the registration is irrevocable for 1 year. After 1 year, you can apply for cancellation if turnover remains below threshold.

What are the special category states and why do they have lower thresholds? ▼

Special category states have lower GST thresholds (₹20L for goods, ₹10L for services vs ₹40L/₹20L for normal states). The 11 special category states are: Arunachal Pradesh, Assam, Himachal Pradesh, Jammu & Kashmir, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, and Uttarakhand. These states receive special consideration due to their geographical challenges, lower economic development, and strategic border locations. The lower threshold brings more businesses into the GST net in these regions.

What happens if I don't register for GST when I should? ▼

Failure to register for GST when required attracts penalties under Section 122 of the CGST Act. The penalty is 100% of the tax due or ₹10,000, whichever is higher. In cases of deliberate tax evasion, the penalty can be even higher, and prosecution may be initiated under Section 132. Additionally, you lose the ability to claim ITC for the period you were unregistered. You must apply for registration within 30 days of becoming liable (i.e., 30 days from crossing the threshold or starting inter-state supply).

Can I opt for the GST Composition Scheme? What are the limits? ▼

The GST Composition Scheme is available for businesses with turnover up to ₹1.5 crore for goods (₹75 lakh in special category states) and ₹50 lakh for service providers or mixed suppliers. Under the scheme, you pay a lower flat tax rate (1%–2% for goods, 6% for services) but cannot claim Input Tax Credit, cannot make inter-state supplies, cannot sell through e-commerce, and must issue a “Bill of Supply” instead of a tax invoice. It suits small businesses with minimal purchases and local B2C customers. You must opt in at the beginning of the financial year.
