Tax and Investing, LTCG, STCG, and 80C Simplified
Most Indians think about tax exactly twice a year. Once in March when their employer asks for proofs. Again in July when the ITR is due. Investing tax is even less understood, which is why so many people get blindsided by it at the worst time, right when they need their money.
This lesson fixes that. We'll cover what taxes apply to which investments, how to legally minimise them, and the simple Section 80C move that gives you ₹46,800 back from the government every year if you're in the 30% bracket.
The two kinds of investment tax
Almost every investment is taxed in one of two ways. Knowing which one applies tells you almost everything.
1. Capital gains tax. Charged when you sell an investment for more than you paid. Different rates apply depending on whether you held for a short period (STCG, short-term capital gains) or a long period (LTCG, long-term capital gains).
2. Income tax (slab rates). Some income from investments (FD interest, savings interest, some debt fund returns) is added to your annual income and taxed at your slab rate.
That's the entire system. Two buckets. Let's break down each asset class.
Equity (stocks and equity mutual funds) after the 2024 budget
The big shake-up came with Union Budget 2024. Rules now:
| Holding period | Type | Tax rate | Exemption |
|---|---|---|---|
| Less than 12 months | STCG | 20% flat | None |
| 12 months or more | LTCG | 12.5% flat | ₹1.25 lakh per year, free |
A worked example. You bought ₹3 lakh of a Nifty 50 index fund in March 2025. In May 2026 (14 months later) you sell it for ₹4 lakh. Your gain is ₹1 lakh. Since you held it for 12+ months, this is LTCG. The first ₹1.25 lakh of LTCG gains every financial year is tax-free. So your entire ₹1 lakh gain pays zero tax.
If instead you'd sold in November 2025 (8 months) for the same ₹4 lakh, the ₹1 lakh gain would be STCG and taxed at 20%, so ₹20,000 in tax. (Note: the post-Budget-2024 rates above apply to transfers on or after 23 July 2024; sales before that date used the old 15% STCG / 10% LTCG schedule.)
Debt mutual funds: the painful 2023 change
Before April 2023, debt mutual funds had a wonderful tax structure. Hold for 3+ years and pay 20% with indexation benefit (which adjusted your cost for inflation, often dropping effective tax to single digits).
After April 2023, the government removed this. Debt mutual fund gains, regardless of holding period, are now taxed at your slab rate. Just like FD interest.
This single change made FDs and debt mutual funds roughly tax-equivalent. For long-term debt allocation, the choice is now mostly about flexibility (debt funds win on liquidity, FDs win on simplicity).
Other asset taxes, quickly
- FD interest. Slab rate, every year, deducted automatically as TDS by the bank.
- Savings account interest. Under the old tax regime, the first ₹10,000 per year is tax-free under Section 80TTA (₹50,000 for senior citizens under 80TTB). Under the new tax regime (default since FY 2023-24), 80TTA is not available and savings interest is fully taxed at slab. Beyond the exemption (when applicable), slab rate.
- Gold (physical, ETF, mutual fund). Same as debt funds now. Slab rate regardless of holding period.
- Sovereign Gold Bonds (SGB). Special. The 2.5% annual interest is taxed at slab rate. But if held to maturity (8 years), capital gains on the gold price appreciation are completely tax-free. Until 2024 this made SGBs the most tax-efficient gold instrument in India. RBI stopped issuing new tranches in February 2024, so you can no longer subscribe to fresh SGBs in the primary market; existing units still trade on NSE/BSE secondary market.
- Real estate. STCG (under 24 months) at slab rate. LTCG (24+ months) at 12.5%. Tax-free if reinvested in another residential property (Section 54).
- Crypto. Brutal: 30% flat on gains, plus 1% TDS on every transaction, no offset of losses against other gains.
Section 80C: the ₹46,800 freebie
If you're in the 30% tax bracket and following the old tax regime, Section 80C allows you to invest up to ₹1.5 lakh per year in specific instruments and deduct that amount from your taxable income. At 30% slab, that's ₹46,800 you don't pay as tax. Free money, every year.
Eligible 80C instruments:
- ELSS (Equity Linked Savings Scheme): equity mutual funds with a 3-year lock-in. Same long-term returns as regular equity funds (~12%), with the 80C deduction on top. Most efficient choice for under-50 investors.
- PPF (Public Provident Fund): 7.1% currently, 15-year lock-in, completely tax-free (interest + maturity). Excellent debt-side instrument for safety + tax efficiency.
- NPS: retirement-focused, offers an extra ₹50,000 deduction beyond 80C under Section 80CCD(1B).
- Life insurance premium: counts for 80C, but mixing insurance with investment is usually a bad idea. Buy term insurance separately (very cheap) and invest the rest separately. Skip endowment/ULIP for 80C.
- Tax-saving FDs (5-year lock-in): counts for 80C but lower return than ELSS or PPF. Use only if you absolutely need full safety.
- Sukanya Samriddhi (for girl child): 8% tax-free, good if you have a daughter under 10.
The simple Section 80C plan for most under-50 Indians:
- ELSS SIP of ₹10,000 per month (₹1.2 lakh annual) for the wealth-building portion
- PPF contribution of ₹30,000 (top up to ₹1.5 lakh)
- That hits the full ₹1.5 lakh 80C limit, gives you ₹46,800 back from the government, and the ELSS portion is doing real long-term wealth building
Old regime vs new regime: the meta-question
In 2020 the government introduced a New Tax Regime. Default for new taxpayers since 2023. Lower slab rates, but no 80C, no HRA, no home-loan interest deduction.
Quick rule of thumb:
- If your total deductions (80C + 80D + home loan interest + HRA + others) exceed roughly ₹3 lakh, stick with old regime to keep the deductions.
- If your deductions are minimal (you rent without HRA, no home loan, no 80C investments), new regime is simpler and slightly better.
Most salaried professionals with 80C ELSS + home loan interest are better off in the old regime. Use the income tax department's free comparison calculator on incometax.gov.in to check your specific case.
Tax-loss harvesting: the legal trick
End of the financial year approaches. You have ₹2 lakh in gains from one fund (taxable). You have ₹50,000 in unrealised losses on another fund. Sell the loss-making fund. Now your net realised gain for the year is ₹1.5 lakh instead of ₹2 lakh. Then buy a similar fund back (not the same one to avoid wash-sale-style issues). You've harvested ₹50,000 of losses against your gains, saving you ~₹6,250 in tax.
This is fully legal. Most retail investors don't bother, but if you have a sizeable portfolio at year-end, it's worth a 30-minute exercise in March.
A real Indian story
For the first 8 years of their careers, Kavitha and Suresh did 80C through whatever their employer's "tax advisor" recommended. That meant ULIPs with 2% fees, an endowment policy with poor returns, and a small ₹40,000 LIC premium. Together they were claiming ₹1.5 lakh each in 80C, getting their ₹46,800 back, and feeling clever.
In 2023 they sat down and actually looked at the returns on those instruments. The ULIPs were giving 5% to 6% net after fees. The endowment was giving 4%. Over 8 years, while they'd saved roughly ₹3.74 lakh in taxes through 80C, their underlying investments had grown at half the rate of a basic ELSS fund.
They quietly stopped the ULIP and endowment (taking minor surrender losses), redirected everything into ELSS funds for the next year's 80C, and kept their existing PPF running. Six months in, the ELSS returns were already showing 14% growth. The total 80C savings stayed the same (₹46,800 a year). But the underlying ₹1.5 lakh was now compounding meaningfully.
The lesson: 80C is a great government subsidy, but only if you put the money into instruments that actually grow. ELSS plus PPF beats almost every other 80C combination for working-age investors.
Key Takeaways
- Equity tax (post-2024): STCG 20% if held under 12 months, LTCG 12.5% with ₹1.25 lakh annual exemption if held 12+ months. Hold longer.
- Debt mutual funds (post-2023): taxed at slab rate, no indexation. Now roughly equivalent to FDs in tax treatment.
- SGBs are tax-magic when you can get them: 8-year hold gives tax-free capital gains on gold appreciation. RBI stopped new SGB issuance in Feb 2024, so this only applies to existing units bought on the secondary market. For fresh gold allocation today, Gold ETFs or Gold Mutual Funds are the realistic options.
- Section 80C saves you up to ₹46,800 per year (30% slab) on ₹1.5 lakh invested. Use ELSS for the wealth-building portion, PPF for the safety portion. Skip ULIPs and endowment.
- Old vs new regime: stick with old if your deductions exceed ~₹3 lakh, otherwise new is simpler.
- Tax-loss harvesting in March can save thousands. Sell losers to offset winners.
