PPF vs ELSS vs SIP: Which Tax-Saving Investment Actually Wins in 2026?

Better at what — they're not substitutes. ELSS offers higher long-term growth potential with market risk and a 3-year lock-in; PPF offers a government-guaranteed, fixed return with a 15-year lock-in. Many investors hold both for different jobs within their 80C bucket.

Yes — they draw from the same combined ₹1.5 lakh limit, so you can split contributions between them (and other 80C instruments) however you like up to that ceiling.

No. An SIP is a payment method. It only contributes to 80C if the underlying fund is an ELSS scheme.

You simply stop claiming it going forward — but money already in PPF or ELSS stays invested under its own rules (PPF keeps earning its declared rate to maturity; ELSS stays locked for its original 3 years from each investment date).

Under current law, yes — PPF is an EEE instrument: the contribution (up to the 80C limit), the interest earned, and the maturity amount are all exempt from tax. This is a feature of today's tax law and could only change through a future Finance Act.

7.1% a year, compounded annually. The government kept small savings rates unchanged for the October-December 2026 quarter, so PPF stays at 7.1%, Sukanya Samriddhi at 8.2% and NSC at 7.7%. Rates are reviewed every quarter, so a 15-year PPF account will not necessarily earn 7.1% throughout.

Each SIP instalment is locked in for 3 years from its own investment date. An ELSS SIP started in January 2026 therefore unlocks month by month from January 2029, not all at once. Gains are long-term when redeemed, taxed at 12.5% above ₹1.25 lakh a year.
