Ever wondered whether a brand‑new startup can dodge taxes in India? The short answer is: not completely free, but the government does hand out a hefty bundle of reliefs that can slash your tax bill for the first few years. Below we break down who qualifies, which sections of law apply, what the actual savings look like, and how to keep the paperwork straight.
Key Takeaways
- Startups meeting the Startup India Initiative criteria - age ≤ 7 years, annual turnover ≤₹100crore, and innovative focus - can claim a 100% rebate on income tax for three out of the first ten years.
- Section 80I of the Income Tax Act provides the legal framework for the rebate and other concessions. applies only after registration with the Startup India portal.
- Angel investors and venture capital funds enjoy a capital‑gains exemption on profits from startup shares, encouraging early‑stage funding.
- GST on export‑linked services remains nil, and intra‑state supplies to other startups get a reduced GST compliance burden.
- Compliance is simple but strict: you must file the startup tax exemption India claim within the first filing year and retain all supporting documents for seven years.
What Exactly Is a “Startup” Under Indian Law?
Before you chase tax breaks, you need to confirm that your business fits the legal definition. The government uses a clear set of parameters:
- Established less than seven years ago.
- Annual turnover (revenue) not exceeding ₹100crore in any fiscal year.
- Working on an innovative product, process, or service that has the potential to generate employment.
When a company meets these points, it can register on the Startup India portal. Registration grants a unique Startup Identification Number (SIN), which you’ll need when filing tax returns.
Core Tax Benefits Explained
The primary reliefs come from two fronts: income tax and capital gains tax.
Income Tax Relief - Section 80I
Section 80I, a clause of the Income Tax Act (the cornerstone legislation governing taxation in India). offers a 100% rebate on taxable income for three out of the first ten years, provided the startup is certified by the Ministry of Commerce & Industry.
How the three years are chosen:
- First year of operation (if turnover <₹50crore).
- Any two subsequent years where the profit‑after‑tax is below the prescribed ceiling (currently ₹5crore).
If you cross the profit ceiling, you can still claim the rebate for the remaining eligible years, but the exemption stops once the three-year limit is exhausted.
Capital Gains Exemption for Early Investors
Angel investors and registered venture capital (VC) funds receive a full exemption on long‑term capital gains (LTCG) when they sell their equity stakes in a certified startup, provided the holding period is at least two years. This is laid out in Section 54EE of the Income Tax Act, and it’s a big incentive for seed‑stage money.

Corporate Tax Rate Reduction - Numbers That Matter
Regular domestic companies in India face a flat corporate tax rate of 25% (30% for those not opting for the concessional regime). Startups, however, can enjoy a reduced rate of 15% for the years they claim the 100% rebate under Section 80I.
Entity Type | Applicable Tax Rate | Rebate Eligibility | Effective Rate After Rebate |
---|---|---|---|
Regular Domestic Company | 25% (30% for non‑concessional) | None | 25% / 30% |
Certified Startup (Year1‑3 of rebate) | 25% | Section80I - 100% rebate | 0% (effective) |
Certified Startup (Post‑rebate years) | 25% | None | 25% |
In plain terms, a startup that qualifies can pay zero income tax on its profit for up to three years-an immediate cash‑flow boost that many founders use to reinvest in product development.
GST and Other Indirect Tax Reliefs
Goods and Services Tax (GST) applies to most businesses, but startups get a few shortcuts:
- If your startup exports services, GST is zero‑rated, meaning you charge no GST to foreign clients and can claim input‑tax credit on purchases.
- Startups with an annual turnover below ₹40lakhs (₹20lakhs for service providers) are exempt from GST registration altogether.
- Through the Special Economic Zone (SEZ) framework, companies set up in designated zones can enjoy a 100% GST exemption on supplies made within the SEZ.
These provisions don’t eliminate GST, but they significantly lower the administrative load for early‑stage ventures.
Step‑by‑Step Compliance Checklist
Getting the tax break is straightforward if you follow a clear process. Here’s a practical checklist you can print out:
- Register on the Startup India portal and obtain a SIN.
- Secure certification from the Department for Promotion of Industry and Internal Trade (DPIIT).
- Maintain audited financial statements for every fiscal year.
- File your income‑tax return using ITR‑3 (or ITR‑4 for presumptive taxation) and attach the certification letter.
- If claiming the 100% rebate, mark the “Tax Relief under Section80I” box and specify the applicable financial year.
- Keep all supporting documents-incorporation certificate, SIN, DPIIT letter, audit reports-for at least seven years.
- For angel or VC investors, ensure the share purchase agreement references Section54EE eligibility and the two‑year holding period.
Missing any of these steps can delay the rebate or lead to a denial, so double‑check before you hit “Submit”.

Common Pitfalls and How to Avoid Them
- Missing the DPIIT certification. Without the official letter, the tax department treats you as a regular company.
- Exceeding the turnover ceiling. If your revenue jumps past ₹100crore, you instantly lose startup status.
- Improper classification of profit. The rebate only applies to profits after all deductions; disguising expenses can raise red flags.
- Late filing. The claim must be made in the same financial year the profit is earned; delayed filing means you miss the window.
- Skipping GST registration when required. Even if you’re exempt from paying GST, you may still need to register to claim input credits.
Next Steps for Founders
If you’re ready to claim the tax break, start by uploading your incorporation documents to the Startup India portal. Most founders find it helpful to loop in a chartered accountant who’s familiar with Section80I. The accountant can also prepare the audit report in the format the Income Tax Department expects.
Beyond taxes, consider leveraging other government schemes-such as the Fund of Funds for Startups (FFS) and credit guarantee funds-to fuel growth without diluting equity.
Frequently Asked Questions
Can a startup claim the 100% tax rebate every year?
No. The rebate is limited to three years out of the first ten years of operation, and only if the profit stays below the prescribed ceiling. Once the three-year quota is used, the startup pays the regular corporate tax rate.
Do I need to register for GST if my turnover is below ₹40lakhs?
You’re exempt from charging GST, but you may still register voluntarily to claim input tax credit on purchases. Voluntary registration can be beneficial if you incur significant GST on inputs.
What happens if my startup’s turnover exceeds ₹100crore?
Exceeding the ₹100crore limit automatically revokes your startup status. You’ll lose any pending tax rebates and must start filing returns as a regular company from the next financial year.
Are foreign investors eligible for the capital‑gains exemption?
Yes, provided the foreign investor is classified as a “specified person” under Section54EE and meets the two‑year holding requirement. The exemption applies to both Indian and non‑resident investors.
Do I need to re‑apply for the tax rebate each year?
No separate application is needed after the initial certification. You simply claim the rebate in the income‑tax return for each eligible year, attaching the same DPIIT certification.
