Health Insurance GST Is Zero Now — But Your Premium Still Rose. Where Did the 18% Go?

It's been one full year since the government cut GST on health insurance premiums from 18% to zero. On paper, your premium bill should have dropped sharply in September 2025. Yet millions of Indians are opening renewal notices in 2026 and staring at bills that are the same — or higher — than before. What happened to the 18%? This is the story of a well-intentioned tax cut, an accounting reality insurers call the ITC problem, and a market where premiums were already climbing fast. Let's decode it step by step — and then talk about what you can actually do at your next renewal.

What changed on September 22, 2025

At its 56th meeting in early September 2025, the GST Council announced that all individual health insurance policies — including family floater plans and policies for senior citizens, plus reinsurance on such plans — would be exempt from GST. The new rate took effect on September 22, 2025. Before that, a ₹25,000 base premium meant paying ₹29,500 after 18% GST. After the change, the same base premium should show ₹25,000 with the GST line at zero. Employer-paid group health policies, however, continued to carry 18% GST — the exemption applies only to individual policies.

So why didn't your renewal get 18% cheaper?

Because insurers don't just lose the GST they used to collect — they also lose the GST they used to claim back. Under the old system, insurers collected 18% GST from you but also claimed input tax credit (ITC) on the GST they paid to vendors: IT systems, third-party administrators (TPAs), call centres, marketing, agent commissions, office rent. The two offset each other. Under the CGST Act, once a service becomes exempt, the ITC on inputs is blocked (Section 17(2)). The vendor GST that insurers used to adjust against collections now sits inside their operating cost — and a portion of it can flow into base premiums. Analysts flagged this at the time. A Kotak Institutional Equities report projected in March 2026 that insurers could raise base tariffs by 3–5% to compensate for lost ITC. That's a projection, not a confirmed universal hike — but it explains why “₹20,000 + 18% GST” didn't simply become “₹20,000 flat”. If your insurer revised the base to ₹20,600, you'd pay ₹20,600 instead of ₹23,600 — still less than before, but not the full 18% saving.

The bigger story: premiums were already rising fast

The GST cut landed in a market where health premiums were climbing sharply. A nationwide LocalCircles survey of 17,200+ respondents across 320 districts found that more than 70% of policyholders saw cumulative premium increases of 50–200% over three years (2022–2025): 21% saw their premiums rise 200% or more, 11% saw 150–200%, and 21% saw 100–150%. A separate LocalCircles survey found 52% of respondents had seen premiums rise by more than 25% in just the last 12 months. Insurers attribute the hikes to medical inflation, costlier hospital bills, and in some cases the repricing of older, loss-making products. Claim experiences, meanwhile, haven't kept pace — which is exactly why the regulator is now tightening timelines.

What the numbers say one year later

The GST relief did move the market. In a story published on September 28, 2026, ET/BFSI reported that Star Health — India's largest standalone health insurer — saw its retail policy base grow 11% between October 2025 and August 2026, up from barely 2% a year earlier. The average sum insured on fresh retail policies rose ₹1.4 lakh to ₹13.7 lakh, and buyers aged 26–50 drove more than 80% of net policy additions. Cheaper headline premiums are pulling younger buyers in. Across the industry, Business Standard reported non-life insurers logged roughly 9.3% premium growth in FY26 after the GST relief, with health now the largest line of business. Star Health's premium rose 11.3% to ₹18,605.5 crore, Care Health grew 20.91% to ₹10,031 crore, and Niva Bupa surged 27% to ₹8,585.9 crore. ICRA expects 9.7–10.6% growth in FY27, with health the primary driver.

What IRDAI guarantees you on claims

Rising premiums sting less when claims are honoured promptly. IRDAI's health insurance norms set firm timelines: for cashless claims, the insurer must decide on pre-authorisation within 1 hour and give final discharge authorisation within 3 hours; reimbursement claims must be settled within 15 days. Other guardrails every policyholder should know: waiting period for pre-existing diseases (PED) capped at 36 months; moratorium period of 60 months, after which claims generally can't be rejected on non-disclosure grounds except proven fraud; free-look period of 30 days to return a new policy for a refund; grace period for renewal of 30 days; and portability notice of 45 days before renewal if you want to switch insurers. IRDAI's claim settlement data (FY2024–25, released February 2026) shows Aditya Birla Health, Galaxy, Narayana and Niva Bupa each settled 100% of claims within three months; Acko was at 99.98%. A faster-settling insurer is one data point — not a reason to buy — but it's worth checking before you renew.

Special protection for senior citizens

IRDAI has capped the annual premium increase at 10% for senior citizen health policies — a meaningful guardrail, since premiums in retirement are typically the highest. If your parent's renewal jumps more than that, question it in writing and escalate through the insurer's grievance channel.

Your 5-point renewal checklist

1. Check the invoice break-up. Look for a clean base premium line and a GST line at 0%. If the base moved up, ask what changed. 2. Know your policy type. The 0% rate covers individual policies including family floaters. Employer group plans still carry 18% GST. 3. Watch the payment date. For instalments, the rate depends on when the payment is posted in the insurer's system. 4. Compare like for like. Don't chase the lowest premium — compare sum insured, room-rent caps, co-pay clauses, waiting periods, and claim-settlement speed. 5. Use the free-look and portability windows. 30 days to return a new policy, 45 days' notice to port. These are rights, not favours.

The bottom line

The GST exemption was real relief — but it removed only the tax line, not the forces pushing base premiums up: medical inflation, richer hospital bills, and the blocked input credits insurers absorbed. Whether your renewal actually costs less depends on your insurer's base revision. Ask for the break-up, know your IRDAI timelines, and renew with eyes open.
