NSC Pays 7.7%. PPF Pays 7.1%. But After Tax, PPF Wins by Rs 58,000 on Every Lakh Over 15 Years.
National Savings Certificate looks like the smarter pick. Higher rate than PPF. Only 5-year lock-in instead of 15. Same Section 80C benefit.
But NSC interest is taxable. PPF interest is not.
At the 30% bracket, NSC’s 7.7% becomes 5.39% post-tax. PPF’s 7.1% stays 7.1%.
And there is a lesser-known trick — NSC’s accrued interest in Years 1-4 qualifies for additional 80C deductions without you investing a single extra rupee. This partially offsets the tax drag. But it works only under the old regime, and Year 5 has no such shield.
This guide shows the exact post-tax yield of NSC compared to PPF, SCSS, and bank FDs at every tax bracket — with the 80C accrued interest trick, the Year 5 tax bomb, and the regime-switching trap that nobody talks about.
Current Rates: Q1 FY 2026-27 (April-June 2026)
All rates unchanged for the eighth consecutive quarter.
| Instrument | Rate (p.a.) | Compounding | Tax on Interest | Lock-in | TDS? |
|---|---|---|---|---|---|
| NSC | 7.70% | Annual (reinvested) | Taxable at slab | 5 years | No |
| PPF | 7.10% | Annual | Tax-free (EEE) | 15 years | No |
| SCSS | 8.20% | Quarterly payout | Taxable at slab | 5 years | Yes (above Rs 1L) |
| SBI FD (5-yr) | 6.40% | Quarterly | Taxable at slab | 5 years | Yes (above Rs 50K) |
| HDFC FD (5-yr) | 6.50% | Quarterly | Taxable at slab | 5 years | Yes (above Rs 50K) |
| Post Office TD (5-yr) | 7.50% | Quarterly | Taxable at slab | 5 years | No |
Key difference most tables hide: NSC and Post Office TD have zero TDS. Bank FDs deduct 10% TDS when interest crosses Rs 50,000/year (Rs 1 lakh for senior citizens). This means FD interest compounds at 90% efficiency while NSC compounds at 100% — the gap adds up over 5 years. Check current bank FD rates across 40+ institutions to compare with NSC before deciding.
The Post-Tax Yield Table: NSC vs PPF vs SCSS vs Bank FD
New Tax Regime — Post-Tax Annualized Returns (No 80C Available)
Under the new regime, Section 80C does not apply. NSC loses both its principal deduction and the accrued interest trick. Only the raw rate minus tax matters.
| Marginal Tax Rate | NSC (7.70%) | PPF (7.10%) | SCSS (8.20%) | SBI FD (6.40%) |
|---|---|---|---|---|
| 0% (up to Rs 4L) | 7.70% | 7.10% | 8.20% | 6.40% |
| 5% (Rs 4-8L) | 7.32% | 7.10% | 7.79% | 6.08% |
| 10% (Rs 8-12L) | 6.93% | 7.10% | 7.38% | 5.76% |
| 15% (Rs 12-16L) | 6.55% | 7.10% | 6.97% | 5.44% |
| 20% (Rs 16-20L) | 6.16% | 7.10% | 6.56% | 5.12% |
| 25% (Rs 20-24L) | 5.78% | 7.10% | 6.15% | 4.80% |
| 30% (above Rs 24L) | 5.39% | 7.10% | 5.74% | 4.48% |
The crossover: at 10% marginal rate, PPF overtakes NSC. Above 10%, PPF beats every other instrument in this table.
At the 30% bracket:
- PPF beats NSC by 171 bps (7.10% vs 5.39%)
- PPF beats SCSS by 136 bps (7.10% vs 5.74%)
- PPF beats SBI FD by 262 bps (7.10% vs 4.48%)
- To match PPF’s 7.10% post-tax, you need a taxable instrument paying 10.14% pre-tax
No government scheme or major bank FD offers 10.14%.
Old Tax Regime — Post-Tax Returns With 80C Benefit
Under the old regime, NSC unlocks a unique advantage: the accrued interest 80C trick (explained below). This partially offsets the tax drag in Years 1-4.
| Marginal Tax Rate | NSC (7.70%)* | PPF (7.10%) | SCSS (8.20%)** | SBI FD (6.40%) |
|---|---|---|---|---|
| 0% | 7.70% | 7.10% | 8.20% | 6.40% |
| 10% | 7.22% | 7.10% | 7.38% | 5.76% |
| 20% | 6.75% | 7.10% | 6.56% | 5.12% |
| 30% | 6.27% | 7.10% | 5.74% | 4.48% |
*NSC old regime returns include the tax benefit of 80C on accrued interest in Years 1-4. Year 5 interest is fully taxable.
**SCSS old regime returns for seniors include 80TTB deduction of Rs 1 lakh on interest income.
Even with the 80C trick, PPF still wins at 20% and above. The trick narrows the gap from 171 bps to 83 bps at 30% — meaningful, but not enough to flip the result.
NSC’s Hidden 80C Trick: Rs 33,500 in Extra Deductions on Rs 1 Lakh
This is the most underutilized tax feature in Indian small savings — and almost no comparison article calculates it correctly.
How It Works
NSC interest is compounded annually and reinvested into the certificate. This “deemed reinvestment” qualifies as a fresh Section 80C investment each year.
On Rs 1,00,000 invested at 7.7%:
| Year | Opening Balance | Interest Accrued | 80C Claim on Accrued Interest | Tax Saved (30% slab) |
|---|---|---|---|---|
| Year 1 | Rs 1,00,000 | Rs 7,700 | Rs 7,700 | Rs 2,310 |
| Year 2 | Rs 1,07,700 | Rs 8,293 | Rs 8,293 | Rs 2,488 |
| Year 3 | Rs 1,15,993 | Rs 8,931 | Rs 8,931 | Rs 2,679 |
| Year 4 | Rs 1,24,924 | Rs 9,619 | Rs 9,619 | Rs 2,886 |
| Year 5 | Rs 1,34,543 | Rs 10,360 | Rs 0 (no deduction) | Rs 0 |
| Total | Rs 44,903 | Rs 34,543 | Rs 10,363 |
Year 5 is the trap. The final Rs 10,360 in interest has no 80C offset — it is fully taxable at your slab rate.
The Fine Print
- This trick only works under the old tax regime. New regime taxpayers get zero benefit.
- The accrued interest 80C claim is subject to the overall Rs 1.5 lakh annual limit. If your EPF, PPF, ELSS, and insurance premiums already exhaust the limit, the NSC accrued interest deduction is wasted.
- You must declare accrued interest as income from other sources each year in your ITR, then claim the 80C deduction separately. Many investors skip both steps — then get hit with the full Year 5 tax.
The Year 5 Tax Bomb
NSC does not deduct TDS. The post office pays you the full maturity amount without withholding anything.
This creates a dangerous pattern:
- Years 1-4: You claim 80C on accrued interest → net tax effect is near-zero
- Year 5: Rs 10,360 in interest per lakh invested hits your income with no 80C offset
On a larger investment of Rs 10 lakh, the Year 5 interest is approximately Rs 1,03,600. At the 30% slab, that is Rs 31,080 in tax — due as a lump sum in your ITR filing.
If you hold multiple NSC certificates maturing in the same year, the cumulative Year 5 interest can push you into a higher tax bracket.
Planning tip: Stagger your NSC purchases across different years. Buy Rs 2 lakh/year for 5 years instead of Rs 10 lakh in one shot. This spreads the Year 5 tax impact across 5 different assessment years.
The Regime-Switching Trap
Nobody discusses this scenario. But it affects anyone who changes their mind mid-tenure.
Scenario: You buy NSC in April 2026 under the old regime. You claim 80C on principal (Year 1) and accrued interest (Years 2-3). In FY 2029-30, you switch to the new regime.
What happens:
- Years 1-3: You benefited from 80C deductions on principal + accrued interest. This benefit is gone — you cannot reclaim it, but you also do not have to return it.
- Year 4 (new regime): Accrued interest is taxable. No 80C offset available. Full tax at slab rate.
- Year 5 (new regime): Same — full tax, no offset.
The effective post-tax yield on this NSC drops below 5% — worse than if you had been on the new regime the entire time (because at least then you would not have bothered with NSC at all).
Rule: If you invest in NSC for the 80C benefit, commit to the old regime for the full 5-year tenure.
NSC vs Tax-Saving 5-Year Bank FD: Clear Winner
Both NSC and tax-saving FDs have a 5-year lock-in and qualify for 80C. But NSC wins on every metric that matters.
| Feature | NSC (7.7%) | SBI Tax-Saving FD (6.40%) | HDFC Tax-Saving FD (6.50%) |
|---|---|---|---|
| Interest rate | 7.70% | 6.40% | 6.50% |
| Compounding | Annual | Quarterly | Quarterly |
| TDS | None | 10% above Rs 50K | 10% above Rs 50K |
| Premature withdrawal | Not allowed | Not allowed | Not allowed |
| Sovereign guarantee | Yes | No (DICGC Rs 5L) | No (DICGC Rs 5L) |
| 80C (old regime) | Yes + accrued interest trick | Yes (principal only) | Yes (principal only) |
| Maturity on Rs 5L (0% slab) | Rs 7,24,515 | Rs 6,87,120 | Rs 6,90,340 |
| Maturity on Rs 5L (30% slab) | Rs 6,37,160 | Rs 6,14,060 | Rs 6,16,350 |
NSC earns Rs 37,400 more than SBI FD on Rs 5 lakh at the 0% bracket. Even at 30%, NSC leads by Rs 23,100. For detailed FD post-tax calculations at every slab, see the complete FD yield breakdown.
The only advantage of a tax-saving FD over NSC: you can open it online in 5 minutes at your bank. NSC requires a visit to the post office (or an online purchase at India Post’s portal, which is functional but slow).
Rs 1 Lakh Over 5 Years: The Full Comparison
What Rs 1,00,000 actually becomes after tax, at every slab.
At 0% Tax Bracket (Income Below Taxable Limit)
| Instrument | Maturity Value | Post-Tax Gain |
|---|---|---|
| SCSS (8.20%) | Rs 1,49,456 | Rs 49,456 |
| NSC (7.70%) | Rs 1,44,903 | Rs 44,903 |
| Post Office TD (7.50%) | Rs 1,43,563 | Rs 43,563 |
| PPF (7.10%) | Rs 1,40,710 | Rs 40,710 |
| SBI FD (6.40%) | Rs 1,36,581 | Rs 36,581 |
At zero tax, SCSS wins. Higher rate + quarterly payouts (if reinvested). NSC comes second.
At 20% Tax Bracket
| Instrument | Effective Maturity | Post-Tax Gain |
|---|---|---|
| PPF (7.10%) | Rs 1,40,710 | Rs 40,710 |
| NSC (7.70%)* | Rs 1,38,600 | Rs 38,600 |
| SCSS (8.20%) | Rs 1,37,240 | Rs 37,240 |
| Post Office TD (7.50%) | Rs 1,34,850 | Rs 34,850 |
| SBI FD (6.40%) | Rs 1,29,265 | Rs 29,265 |
*With 80C accrued interest trick under old regime.
PPF takes the lead. NSC’s 80C trick keeps it competitive — without the trick, NSC drops to Rs 1,35,922.
At 30% Tax Bracket
| Instrument | Effective Maturity | Post-Tax Gain |
|---|---|---|
| PPF (7.10%) | Rs 1,40,710 | Rs 40,710 |
| NSC (7.70%)* | Rs 1,35,900 | Rs 35,900 |
| SCSS (8.20%) | Rs 1,34,619 | Rs 34,619 |
| Post Office TD (7.50%) | Rs 1,30,494 | Rs 30,494 |
| SBI FD (6.40%) | Rs 1,25,607 | Rs 25,607 |
PPF wins by Rs 4,810 over NSC and Rs 6,091 over SCSS — on just Rs 1 lakh. Scale this to Rs 10 lakh and the gap is Rs 48,000-61,000.
Inflation-Adjusted Real Returns: The Uncomfortable Truth
CPI inflation has averaged 5.5% over the past 5 years. Here is what each instrument actually earns in purchasing power.
| Instrument | Pre-Tax Nominal | Post-Tax (30% slab) | Real Return (After Inflation) |
|---|---|---|---|
| PPF (7.10%) | 7.10% | 7.10% | +1.60% |
| NSC (7.70%) | 7.70% | 5.39% | -0.11% |
| SCSS (8.20%) | 8.20% | 5.74% | +0.24% |
| SBI FD (6.40%) | 6.40% | 4.48% | -1.02% |
At the 30% slab, NSC and bank FDs deliver negative real returns. Your money grows in nominal terms but buys less each year.
PPF is the only instrument that comfortably beats inflation after tax at every bracket.
SCSS barely survives at 30% — and only if you ignore the compounding disadvantage of quarterly payouts sitting idle in a 2.7% savings account.
When NSC Actually Makes Sense
Despite the tax drag, NSC is the right choice in specific situations:
1. You Are in the 0-5% Tax Bracket
At these slabs, NSC’s 7.7% suffers minimal tax leakage (Rs 0 to Rs 3,850 per lakh over 5 years). It beats PPF by 60 bps with a shorter lock-in.
2. You Have Already Maxed PPF (Rs 2 Lakh/Year)
After depositing the maximum Rs 2 lakh in PPF, NSC is the next-best sovereign-guaranteed option. It beats every major bank FD and has no TDS.
3. You Need Sovereign Guarantee but Cannot Wait 15 Years
PPF locks you in for 15 years (partial withdrawal from 7th year). NSC locks you for exactly 5 years. If your goal is in the 5-7 year range, NSC with government backing beats bank FDs on both yield and safety.
4. Your 80C Limit Is Not Exhausted
If your EPF + insurance + ELSS does not hit the Rs 1.5 lakh 80C ceiling, the accrued interest trick gives NSC a meaningful tax advantage over FDs. But only under the old regime.
5. You Are Building a Staggered Maturity Ladder
Buy Rs 2 lakh NSC each year for 5 years. Starting Year 6, one certificate matures every year — creating a self-renewing 5-year sovereign bond ladder with annual liquidity. This is an underrated strategy for conservative investors who want to avoid the PPF 15-year commitment.
When NSC Does NOT Make Sense
1. You Are in the 20%+ Bracket and Have PPF Room
PPF beats NSC by 83-171 bps post-tax at these brackets. Fill PPF first — always.
2. You Are Under the New Tax Regime
No 80C on principal. No 80C on accrued interest. You are paying full tax on a 7.7% instrument that loses to PPF (tax-free under both regimes). There is zero reason to choose NSC over PPF under the new regime.
3. You Are a Senior Citizen
SCSS at 8.2% pays more, offers quarterly income, and the first Rs 1 lakh of interest is shielded by 80TTB. NSC has no 80TTB benefit and no quarterly payouts. SCSS is strictly superior for 60+ investors (up to the Rs 30 lakh limit).
4. You Might Need the Money Before 5 Years
NSC has zero premature withdrawal. No loan facility. No partial redemption. Even PPF allows partial withdrawal from Year 7 and loans from Year 3. If liquidity matters, NSC is the worst choice in this entire comparison.
The Optimal Allocation: How to Use All Four Instruments
For a 40-year-old in the 30% bracket under the old regime with Rs 10 lakh to deploy:
| Instrument | Amount | Why |
|---|---|---|
| PPF | Rs 2,00,000 | Max out the annual limit. Tax-free compounding for 15+ years. |
| NSC | Rs 2,00,000 | Fill remaining 80C room. 5-year sovereign guarantee. Accrued interest 80C trick. |
| Post Office TD (5-yr) | Rs 3,00,000 | 7.50% with sovereign guarantee. Better than any major bank FD. |
| Debt Mutual Fund | Rs 3,00,000 | Indexation benefit on LTCG (after 3 years). More flexible than NSC. |
For a 62-year-old retiree with Rs 30 lakh under the old regime:
| Instrument | Amount | Why |
|---|---|---|
| SCSS | Rs 12,20,000 | Interest (~Rs 1L) fully covered by 80TTB. Zero effective tax. |
| PPF (extension) | Rs 2,00,000/year | Tax-free compounding. No upper age limit for extensions. |
| NSC | Rs 5,00,000 | After SCSS max, sovereign-backed 80C eligible. |
| Post Office MIS | Rs 9,00,000 | 7.4% monthly income for expenses. |
| SBI FD (senior) | Rs 1,80,000 | Short-term liquidity. 7.05% rate. |
How NSC Rate Is Set — and Why It Might Drop
NSC’s 7.7% is not permanent. The rate is reviewed quarterly and benchmarked to the 5-year G-Sec yield in the secondary market.
| Quarter | Formula-Implied Rate | Actual Rate Set | Government Subsidy |
|---|---|---|---|
| Q1 FY25 | ~7.35% | 7.70% | +35 bps |
| Q2 FY25 | ~7.30% | 7.70% | +40 bps |
| Q3 FY25 | ~7.20% | 7.70% | +50 bps |
| Q4 FY25 | ~7.15% | 7.70% | +55 bps |
| Q1 FY26 | ~7.05% | 7.70% | +65 bps |
| Q1 FY27 | ~7.00% | 7.70% | +70 bps |
The government has been subsidizing NSC by 35-70 bps above the formula rate for over 2 years. G-Sec yields have been falling while small savings rates stay frozen. This gap cannot widen indefinitely.
When the cut comes — and it will — existing NSC certificates retain their original rate. Only new purchases get the lower rate. If you are considering NSC, buying now locks in 7.7% for 5 years regardless of future revisions.
Step-by-Step: How to Buy NSC
At Post Office (In-Person)
- Visit any post office with KYC documents (Aadhaar, PAN, passport photo)
- Fill NSC purchase form
- Pay by cheque or demand draft (minimum Rs 1,000, no maximum)
- Receive NSC certificate — now electronic (e-NSC), no paper certificates since 2016
Online via India Post
- Register at India Post’s portal or DOP (Department of Posts) mobile app
- Link your post office savings account
- Purchase NSC electronically
- Certificate credited to your post office account
Important: NSC purchased in the last few days of March still qualifies for that financial year’s 80C deduction. Many investors use this as a last-minute 80C top-up.
Bottom Line: The Decision Framework
Choose PPF if: You are in the 10%+ bracket, can lock money for 15 years, and want the highest post-tax yield with zero risk.
Choose NSC if: You have maxed PPF, are in the 0-10% bracket, want a 5-year sovereign guarantee, and are on the old regime where the 80C trick works.
Choose SCSS if: You are 60+, want quarterly income, and can limit your investment to Rs 12.2 lakh (the 80TTB sweet spot).
Choose bank FD if: You need liquidity, are in the 0% bracket, or need amounts above the government scheme limits.
The instrument with the highest pre-tax rate is not the one that puts the most money in your pocket. Tax treatment is the single biggest variable in fixed-income investing — and the one most comparison articles get wrong.
