DataPulse is a composite B2B SaaS company. 22 engineers, 6 sales reps, 4 founders — all in Indiranagar, Bengaluru. Annual revenue ~₹18 crore by 2015. The founders' CA brought a strategy: "Set up a unit in a Sikkim SEZ. Section 10AA gives you a 100% tax holiday on export profits for 5 years, then 50% for another 5. Plus another 50% for 5 more if you reinvest. Total 15 years of preferential tax."
DataPulse formed "DataPulse SEZ Unit" in the Pakyong industrial park in East Sikkim. Rented a 220 sq ft cabin. Bought three plastic chairs, a printer, a router. Hired a part-time admin for ₹8,000/month to receive mail. All software was still coded in Bengaluru. The "SEZ unit" exported invoices to overseas clients showing the Pakyong address.
For five years it worked. Then a Joint Commissioner visited Pakyong on a routine SEZ verification round. The cabin was empty. The admin was watching cable TV. The printer hadn't been turned on for 11 months.
The next 18 months brought a Sec 132 search, ₹14 crore demand, GAAR invocation. And it would have happened to many similar setups if the 2020 sunset hadn't quietly ended the route for new entrants.
- Sections 10A, 10AA, 80-IB, 80-IC, 80-IE — collectively the "geography-based tax holidays" — gave 5 to 15 years of tax exemption to units set up in SEZs, software technology parks, backward areas, north-east states, etc.
- The genuine policy aim: industrial dispersal away from coastal metros, employment in remote areas, export promotion. Worked partially — Bengaluru's STPI, Hyderabad's HITEC City, the SEZ boom of 2005-2015.
- The abuse pattern: shell unit in the eligible area, real work elsewhere. Or "substantial expansion" of an existing unit recharacterised as a new unit to restart the holiday clock. Or "split" units to skirt size limits.
- India closed the route in phases. Sec 10A sunsetted 2011. 80-IB / 80-IC mostly sunsetted by 2014. Sec 10AA SEZ: no new units after 31 March 2020. Existing eligible units continue to enjoy the holiday for the remaining years of their original 15-year window.
- The replacement: Sec 115BAB — flat 15% rate for new manufacturing companies set up before 31 March 2024 (extended); Sec 115BAA — 22% rate for any domestic company; Sec 80-IAC — startup deduction for DPIIT-recognised startups. Geographic holidays gone, sector + form holidays remain.
The five geography-based holidays — what each was
Sec 10A (STPI)
Sunset 2011
Software Technology Park (STP) units exporting software. 100% deduction for 10 years. Powered Bengaluru / Hyderabad / Pune software boom. Sunsetted 31 March 2011.
Sec 10AA (SEZ)
Sunset Mar 2020
Special Economic Zone units. 100% deduction first 5 years, 50% next 5, 50% of reinvested profits for further 5. No new units after 31 March 2020; existing units continue. The big SEZ developments — Mumbai NaviSEZ, Cochin, Mahindra World City — all ride this regime for remaining years.
Sec 80-IB / 80-IC
Backward areas, sunset
Industrial units in notified backward areas (Himachal, Uttarakhand, J&K, North-East). 100% / 30% deductions for varying periods. Phased sunset mostly by 31 March 2014. Created the Baddi (HP) and Pantnagar (UK) industrial corridors of the 2000s.
Sec 80-IE (NE)
Sunset 2017
Manufacturing in eight North-Eastern states + Sikkim. 100% deduction for 10 years. Sunset 31 March 2017. DataPulse's Sikkim location originally pitched under this scheme; pivoted later to claim Sec 10AA via a registered SEZ unit.
Sec 80-IAC
Active (FY 25-26)
DPIIT-recognised eligible startup deduction. 100% profit deduction for any 3 consecutive years out of 10. Conditions: incorporated 1 Apr 2016 onwards, turnover ≤ ₹100cr, eligible-business category. Currently active and growing in popularity.
Sec 80LA (GIFT IFSC)
Active
Units in International Financial Services Centre (currently GIFT City Gandhinagar). 100% deduction for 10 out of 15 years. Plus full GST exemption + light-touch regulation. The modern domestic SEZ alternative.
The DataPulse playbook — and what went wrong
Lease 220 sq ft cabin in Pakyong SEZ. Register as DataPulse SEZ Unit. Get the SEZ-letter-of-approval. Pakyong became operational around 2010 as a notified SEZ.
Foreign clients pay invoices issued by "DataPulse SEZ Unit, Pakyong". Bank account in Sikkim. Books prepared at Pakyong "office". Revenue recognised in the SEZ books.
FY 2015-16 to 2019-20: ₹14 crore of taxable profit reduced to ₹0 via Sec 10AA. Tax saved ≈ ₹4.2 crore at 30% rate.
Joint Commissioner audit. Findings: 1 admin at the cabin, no actual development team, no salary payments to Sikkim addresses, all engineering UPIs to Bengaluru, all client calls from Bengaluru phone records. The "unit" exists only on paper.
AO holds the SEZ unit had no commercial substance. Sec 10AA deduction reversed retroactively. ₹14cr addition + 100% penalty under Sec 74 (fraud / willful misstatement) + 18% interest from each FY. Total exposure: ~₹35 crore.
From 1 April 2017, GAAR (Sec 95-102) explicitly addresses "lack of commercial substance" as a ground for treating an arrangement as impermissible. The shell SEZ unit is the classic example. The AO doesn't need GAAR to disallow Sec 10AA — the section itself requires the unit to actually exist and operate. But GAAR adds an explicit "main-purpose-is-tax-benefit" test that closes residual ambiguity.
The legitimate Sec 10AA story — what worked
The geography-based holidays weren't all abuse. Many genuine industrial / IT corridors are direct results:
- Baddi (Himachal) — Sec 80-IC built a real pharma manufacturing belt. Dabur, Cipla, Cadila, Glenmark all have manufacturing units there. ₹40,000+ crore of pharma capacity that wouldn't have existed otherwise.
- Pantnagar (Uttarakhand) — Sec 80-IC powered the auto-component industry there. Tata Motors' Sanand-region plants benefited from parallel state-level holidays.
- NaviSEZ (Mumbai), Mahindra World City (Chennai) — Sec 10AA-driven IT and engineering services capacity expansion.
- STPIs of the 1990s-2000s — Sec 10A enabled the entire Indian software-services-export boom. TCS, Infosys, Wipro built large units; most major Indian IT cities became what they are.
The policy paid off where units were genuine — actual buildings, actual employees, actual investment. The shell-unit abuse was a side effect, not the main story.
The post-2020 replacement architecture
India's tax-incentive design has moved from geography to sector + form. The three replacements:
Sec 115BAB
15% for new mfg
New manufacturing companies set up after Oct 2019. Flat 15% corporate tax rate (plus surcharge + cess → ~17.5% effective). No deductions; pure rate concession. Sunset for setting up extended to 31 Mar 2024 by various Finance Acts; further extension under discussion.
Sec 115BAA
22% any domestic co
Any domestic company opting in. 22% rate (vs 30% otherwise). No new investment required; existing companies can opt in. No restrictions on geography / sector. Most listed Indian companies have opted in since FY 19-20.
Sec 80-IAC
Startup 100%
DPIIT-recognised eligible startups. 100% profit deduction for any 3 consecutive years out of first 10 years. Conditions: incorporated since 1 Apr 2016, turnover ≤ ₹100 crore, eligible-business category. Companies typically time the 3-year window to peak-profitability years.
What the abuse closed and what remains
No longer works
Closed routes
Pure paper-shell SEZ unit (substance test fails). New 10AA unit after Mar 2020 (sunset). Backward-area shell company in Himachal / NE (10C / 80-IB / 80-IE all sunsetted). "Substantial expansion" re-characterised as new unit (anti-abuse case law solidified).
Still works
Legitimate routes
Existing 10AA units (residual years of original 15-year window). 115BAB for genuine new manufacturing investment. 115BAA opt-in for general domestic companies. 80-IAC for genuine DPIIT-recognised startups. GIFT City 80LA for IFSC units with real operations. All require real commercial substance.
The funny historical wrinkle
India's geography-based tax incentives followed roughly the same arc twice:
- 1989-2011 (STPI / Sec 10A) — created the Indian software export industry. By 2011, the IT majors were profitable enough that the holiday was withdrawn. Industry argued it would die; instead, it kept growing.
- 2005-2020 (SEZ / Sec 10AA) — created the SEZ developer industry + IT services capacity expansion. By 2020, SEZs were heavily criticised for shell-unit abuse and revenue loss. Sunset for new units; existing units grandfathered.
The pattern: 5-10 years of policy-driven boom, 5 years of refinement, sunset for new entrants, transition to a different incentive design. The Indian tax-incentive architecture is now in its "sector + form" phase — 115BAB for manufacturing, 80-IAC for startups, 80LA for IFSC — replacing "set up here and we'll spare you" with "do this kind of business and we'll spare you". Whether this is more robust against abuse is the open question for the next decade.
What founders should think about today
- Sec 115BAB is the closest analogue to the old geography holidays — but requires actual manufacturing investment, no leverage on services-only businesses.
- Sec 80-IAC is the underused gem — DPIIT recognition is largely procedural; the 3-year profit-deduction window is materially valuable to fast-growing startups.
- GIFT City IFSC under Sec 80LA is the new "domestic Singapore" for fund management, fintech, insurance. Real building, real employees, real tax shelter.
- SEZ / 10AA window is closed for new units but if you're an existing eligible unit, plan the 15-year cycle carefully. Year 11-15 (50% reinvestment) is the most-missed lever.
- The "lift a shell company into an eligible zone" play is firmly dead. Substance test + GAAR + Sec 132 search risk + 100% penalty under Sec 74 — the risk-reward has inverted vs the early 2010s.
Quick answers
No — the sunset of 31 March 2020 closed new units. Existing units that obtained their letter-of-approval before that date continue to enjoy their original 15-year holiday window. New investment goes via 115BAB (manufacturing) or 80-IAC (startup) instead.
Same spirit, different execution. GIFT IFSC has its own regulator (IFSCA), targets fund management / fintech / insurance / banking, and Sec 80LA gives 100% deduction for 10 of 15 years. Located in Gandhinagar, Gujarat. Real commercial substance is non-negotiable.
The holiday period ends and your unit's profits become taxable at the normal corporate rate (or 115BAA's 22% if you opt in). Some companies wind down the SEZ unit post-15 years and shift operations to the parent's books to avoid SEZ compliance overhead.
Yes — the recognition itself is largely procedural (online application, documents). The Sec 80-IAC certificate of eligibility is separately granted by Inter-Ministerial Board, more selective. Plan the certification cycle to align with peak-profit years.
The original 31 March 2024 deadline was extended; Finance Bills have considered further extension. Check the latest notification. If your manufacturing investment is in pipeline, monitor closely; the rate concession is worth ₹100s of crore over the lifecycle.
When you might want help
Two situations: (1) Existing 10AA unit nearing year 15 — winding down vs continuing strategy + opt-in to 115BAA. (2) New investment evaluating 115BAB vs 80-IAC vs 80LA route + DPIIT certification + IFSC setup support.
Evaluating tax-incentive strategy?
115BAB / 80-IAC / 80LA fit analysis + DPIIT certification + GAAR substance documentation. Fixed scope.
