Every “PPF vs FD vs SCSS” Article Compares Gross Rates. This One Shows You the Exact Post-Tax Yield at YOUR Bracket — and Why the Obvious Choice Is Often Wrong.
PPF: 7.1%. SCSS: 8.2%. SBI FD: 6.05%.
You have seen these numbers. SCSS looks like the winner. Financial advisors tell retirees to max out SCSS first. Internet articles rank SCSS above PPF because 8.2 > 7.1.
They are comparing pre-tax rates. You earn post-tax returns.
At the 30% bracket, SCSS yields 5.74%. PPF yields 7.10%. The “lower rate” instrument wins by 136 basis points.
This guide shows the exact post-tax return of PPF, FD, and SCSS at every tax bracket under both old and new regimes — with the Rs 12.2 lakh SCSS allocation trick, the PPF extension trap that costs lakhs, and the split strategy that yields 7.55% for senior citizens.
Current Rates: April-June 2026 (Q1 FY 2026-27)
Small savings rates were announced on March 30, 2026 — all rates unchanged.
| Instrument | Rate (p.a.) | Compounding | Tax Status | Lock-in |
|---|---|---|---|---|
| PPF | 7.10% | Annual | Tax-free (EEE) | 15 years |
| SCSS | 8.20% | Quarterly payout | Taxable at slab | 5 years |
| Post Office TD (5-yr) | 7.50% | Quarterly, credited annually | Taxable at slab | 5 years |
| NSC | 7.70% | Annual (reinvested) | Taxable at slab | 5 years |
| SBI FD (5-yr, regular) | 6.05% | Quarterly | Taxable at slab | 5 years |
| SBI FD (5-yr, senior) | 7.05% | Quarterly | Taxable at slab | 5 years |
PPF rate has been 7.1% since April 2020 — unchanged for over 6 years. SCSS rate has held at 8.2% since April 2023.
Bank FD Rates vs Government Schemes
| Bank/Issuer | 5-Year Rate (Regular) | 5-Year Rate (Senior Citizen) | Sovereign Guarantee? |
|---|---|---|---|
| SBI | 6.05% | 7.05% | No (DICGC Rs 5L) |
| HDFC Bank | 6.10% | 6.95% | No (DICGC Rs 5L) |
| Post Office TD | 7.50% | 7.50% | Yes |
| Unity SFB | 7.50% | 9.00% | No (DICGC Rs 5L) |
| Ujjivan SFB | 7.45% | 7.95% | No (DICGC Rs 5L) |
| PPF | 7.10% | 7.10% | Yes |
| SCSS | 8.20% | 8.20% | Yes |
Post Office 5-year TD pays 7.50% with sovereign guarantee — 145 basis points more than SBI FD. Both qualify for 80C. The post office option is massively underutilized. For a full breakdown of current FD rates across 40+ banks, SFBs, and NBFCs, see our FD rates comparison.
The Post-Tax Yield Table: Where the Real Comparison Happens
This is the table that changes everything. All calculations use FY 2026-27 new tax regime slabs.
New Tax Regime — Post-Tax Returns
| Marginal Tax Rate | PPF (7.10%) | SCSS (8.20%) | SBI FD 5yr (6.05%) | Post Office TD 5yr (7.50%) |
|---|---|---|---|---|
| 0% (up to Rs 4L) | 7.10% | 8.20% | 6.05% | 7.50% |
| 5% (Rs 4-8L) | 7.10% | 7.79% | 5.75% | 7.13% |
| 10% (Rs 8-12L) | 7.10% | 7.38% | 5.45% | 6.75% |
| 15% (Rs 12-16L) | 7.10% | 6.97% | 5.14% | 6.38% |
| 20% (Rs 16-20L) | 7.10% | 6.56% | 4.84% | 6.00% |
| 25% (Rs 20-24L) | 7.10% | 6.15% | 4.54% | 5.63% |
| 30% (above Rs 24L) | 7.10% | 5.74% | 4.24% | 5.25% |
The crossover point is at 10%. Above the 10% marginal rate, PPF beats SCSS on post-tax returns. SCSS wins only at 0% and 5% brackets.
At the 30% bracket, the gap is massive:
- PPF beats SCSS by 136 bps (7.10% vs 5.74%)
- PPF beats SBI FD by 286 bps (7.10% vs 4.24%)
- To match PPF’s 7.10% tax-free, you need an FD paying 10.14% pre-tax at 30% slab
No major bank offers 10.14%. Not even close.
What Budget 2026 Changed — and Why Old Comparisons Are Wrong
| Change | Before | After (FY 2026-27) | Impact |
|---|---|---|---|
| PPF annual deposit limit | Rs 1,50,000 | Rs 2,00,000 | Rs 7.27L more over 15 years at 7.1% |
| 80TTB deduction (seniors) | Rs 50,000 | Rs 1,00,000 | Shields Rs 1L of FD/SCSS interest from tax |
| TDS threshold (seniors) | Rs 50,000 | Rs 1,00,000 | Less TDS deduction, better cash flow |
| Form 15G/15H | Active | Replaced by Form 121 | New unified declaration from April 2026 |
| PPF partial withdrawal | From 7th year | From 7th year (confirmed, not changed further) | Earlier access to locked funds |
If you are reading a PPF vs SCSS comparison that shows the old Rs 1.5L PPF limit or Rs 50K 80TTB deduction, the numbers are outdated.
The Tax Treatment That Changes Everything
PPF: EEE (Exempt-Exempt-Exempt)
- Deposit: Deductible under 80C up to Rs 1.5L (old regime only)
- Interest: Completely tax-free — regardless of regime
- Maturity: Completely tax-free
- TDS: Never. Zero. In any situation.
PPF is the only fixed-income instrument where your post-tax return equals your pre-tax return. At every bracket. Under both regimes. Your choice of old vs new tax regime determines whether you get the 80C deduction on contributions — but the tax-free interest benefit works regardless.
SCSS: EET (Exempt on deposit, Exempt — no, Taxable on interest)
- Deposit: 80C deduction up to Rs 1.5L (old regime only)
- Interest: Fully taxable at your slab rate
- TDS: 10% on interest exceeding Rs 1L/year (senior citizens)
- Trap: TDS at 10% ≠ your actual tax. If you are in the 30% bracket, you owe an additional 20% on assessment.
Many retirees assume TDS is the final tax. It is not. The TDS-to-actual-tax mismatch is the single most common SCSS complaint on investor forums.
FD: Fully Taxable
- Deposit: 80C for 5-year tax-saver FD only (old regime)
- Interest: Taxable at slab rate — on accrual basis, not at maturity
- TDS: 10% on interest exceeding Rs 50K/year (Rs 1L for seniors from April 2025)
The accrual taxation is the FD trap nobody warns about. A Rs 10L cumulative FD at 7% generates ~Rs 70,000/year in phantom taxable income. You owe tax each year even though you receive nothing until maturity. For a complete post-tax FD yield table at every bracket, see our FD post-tax yield guide.
Old Regime vs New Regime: Which Benefits These Instruments More?
| Benefit | Old Regime | New Regime |
|---|---|---|
| 80C (PPF/SCSS/FD principal, up to Rs 1.5L) | Available | Not available |
| 80TTB (senior interest deduction, up to Rs 1L) | Available | Not available |
| PPF interest tax-free | Yes | Yes |
| FD/SCSS interest taxable at slab | Yes | Yes |
| Standard deduction | Rs 50,000 | Rs 75,000 |
For PPF investors: Old regime gives you the 80C deduction on contributions. New regime does not. But the interest is tax-free in both — that is the bigger benefit.
For SCSS investors: Old regime gives you both 80C on principal AND 80TTB on interest. New regime gives you neither. SCSS is dramatically worse under new regime for taxpaying seniors.
For FD investors: Old regime gives 80C on 5-year tax-saver FD. New regime gives nothing. But the 80C benefit caps at Rs 1.5L — shared with EPF, PPF, LIC, ELSS, and children’s tuition. FD rarely gets any share of this limit.
Bottom line: If you hold SCSS and pay tax on the interest, the old regime is almost always better because of the Rs 1L 80TTB deduction. Switching to new regime and holding SCSS is one of the most expensive mistakes retirees make. See the complete old vs new regime comparison for the breakeven at every salary level.
The Rs 12.2 Lakh SCSS Sweet Spot
This is the number that changes how senior citizens should allocate.
The math:
- SCSS rate: 8.2%
- 80TTB deduction (old regime, Budget 2026): Rs 1,00,000
- SCSS investment needed to generate Rs 1,00,000 interest: Rs 12,19,512 (round to Rs 12.2 lakh)
At Rs 12.2 lakh in SCSS:
- Annual interest: ~Rs 1,00,040
- 80TTB covers the entire amount
- Tax on SCSS interest: Rs 0
- Effective yield: 8.2% (full pre-tax rate, because no tax is paid)
At Rs 30 lakh in SCSS (max limit):
- Annual interest: Rs 2,46,000
- 80TTB covers Rs 1,00,000
- Taxable interest: Rs 1,46,000
- Tax at 30% bracket: Rs 43,800
- Effective yield: 6.74%
The jump from Rs 12.2L to Rs 30L in SCSS costs you Rs 43,800/year in tax and drops your effective yield from 8.2% to 6.74%.
The Optimal Split for a Rs 30L Corpus (Senior Citizen, 30% Bracket, Old Regime)
| Strategy | Annual Income | Tax Paid | Post-Tax Income | Effective Yield |
|---|---|---|---|---|
| 100% SCSS (Rs 30L) | Rs 2,46,000 | Rs 43,800 | Rs 2,02,200 | 6.74% |
| 100% PPF extension (Rs 30L) | Rs 2,13,000 | Rs 0 | Rs 2,13,000 | 7.10% |
| Rs 12.2L SCSS + Rs 17.8L PPF | Rs 2,26,420 | Rs 0 | Rs 2,26,420 | 7.55% |
The split strategy yields 7.55% — beating both pure SCSS (6.74%) and pure PPF (7.10%).
This works because:
- SCSS interest up to Rs 1L is sheltered by 80TTB (zero tax)
- PPF interest is inherently tax-free (zero tax)
- Combined: Rs 2,26,420 in annual income with zero tax liability
PPF Liquidity Is Better Than You Think
The “15-year lock-in” is the most cited reason people avoid PPF. Here is what actually happens:
| Year | What You Can Do |
|---|---|
| Year 1-2 | Nothing. Fully locked. |
| Year 3-6 | Take a loan against PPF (up to 25% of balance at end of 2nd preceding year). Interest: PPF rate + 1%. |
| Year 5+ | Premature closure for medical emergency or higher education. 1% interest penalty on entire balance. |
| Year 7+ | Partial withdrawal: 50% of balance at end of 4th preceding year. One withdrawal per year. No penalty. |
| Year 15+ | Full withdrawal (tax-free). Or extend with/without contributions. |
After year 7, PPF is partially liquid. After year 15, it is fully liquid. The actual hard lock-in period is 5-6 years — not 15.
SCSS Liquidity
| Timeline | What Happens |
|---|---|
| Before 1 year | No premature closure allowed |
| 1-2 years | Premature closure with 1.5% of deposit penalty |
| 2-5 years | Premature closure with 1% of deposit penalty |
| At maturity (5 years) | Withdraw or extend for 3 more years |
| During extension | Premature closure allowed after 1 year with no penalty |
FD Liquidity
Regular FDs offer the best liquidity — break anytime with a 0.5-1% rate penalty. But 5-year tax-saver FDs cannot be broken at all. No premature withdrawal. No loan facility. Zero liquidity for 5 full years.
The PPF Extension Trap: Form H and the Irreversible Mistake
When PPF matures after 15 years, you get three options:
- Withdraw everything — tax-free, no questions asked
- Extend without contributions — balance earns 7.1%, withdraw anytime, no restrictions
- Extend with contributions — continue depositing up to Rs 2L/year, one withdrawal per year (max 60% of balance)
Option 3 requires submitting Form H to your bank or post office within 1 year of maturity.
If you miss this 1-year window, you are permanently locked into Option 2. You can never switch to deposits mode. This is irreversible. No appeal. No exception.
Investor forums have dozens of posts from retirees who missed this deadline. Their PPF account earns 7.1% on the existing balance — which is good — but they can never add to it again. With the new Rs 2L annual limit, this mistake costs up to Rs 14,200/year in lost tax-free interest.
Action item: If your PPF is maturing in the next 12 months, mark the Form H deadline on your calendar. Submit it in the first month, not the last.
SCSS Gotchas Most Advisors Don’t Mention
1. No Auto-Renewal
Unlike FDs, SCSS does not auto-renew. At maturity, if you do nothing, your money sits in a non-interest-bearing account. You must actively visit the branch to extend or withdraw.
2. Extension Rate Reset
When you extend SCSS for another 3 years, the interest rate resets to the prevailing rate at the time of extension — not your original rate. If SCSS rate drops from 8.2% to 7.0% by the time you extend, you get 7.0%.
3. Multiple Extensions Now Allowed
The November 2023 amendment allows unlimited 3-year extensions (previously only one extension was permitted). This is a recent change — many advisors still tell clients it is a one-time extension.
4. Quarterly Payout Creates Tax Complexity
SCSS pays interest quarterly (March 31, June 30, September 30, December 31). This is income in the quarter it is credited — not when you withdraw it. At Rs 30L invested, that is Rs 61,500 per quarter of taxable income to track and declare.
5. The Rs 30 Lakh Cap Is Across All Accounts
The maximum SCSS investment is Rs 30 lakh total — across all SCSS accounts in your name, at all branches and banks combined. You cannot open multiple accounts at different banks to bypass this.
Form 121: The New Declaration That Replaces 15G/15H
From April 1, 2026, Form 121 replaces both Form 15G and Form 15H as a unified self-declaration to request no TDS on deposit interest.
Who needs to file: Anyone whose total income is below the taxable limit and wants to avoid TDS on FD/SCSS/post office deposit interest.
What changes:
- Single form instead of two
- Must be filed at the start of each financial year
- Submitted to your bank, post office, or financial institution
What happens if you don’t file: Your bank deducts 10% TDS automatically on interest exceeding Rs 1L/year (for seniors). You can claim it back via ITR, but your money is blocked for 6-18 months until the refund arrives.
Most senior citizens have not heard of Form 121. If your total income is below the taxable limit, file this form at every institution where you hold deposits — in April, not December.
When Each Instrument Actually Wins
PPF Wins When:
- Your marginal tax rate is 10% or higher
- You want guaranteed, zero-risk, tax-free compounding
- You don’t need regular income (no payout option)
- You are under 60 and have a 15+ year horizon
- You want estate planning benefits (tax-free to nominees, no probate)
SCSS Wins When:
- You are 60+ and in the 0% or 5% tax bracket
- You need quarterly income (Rs 61,500/quarter at Rs 30L)
- You can shelter the interest under 80TTB (invest Rs 12.2L or less)
- You want the highest sovereign-backed rate with a 5-year horizon
FD Wins When:
- You need liquidity (break anytime)
- Your investment exceeds SCSS cap (Rs 30L) and PPF limit (Rs 2L/year)
- You are in the 0% tax bracket (full rate retained, no lock-in)
- You want a loan against your deposit (80-90% of FD value at most banks)
- You need tenure flexibility (7 days to 10 years)
The Split Strategy Wins When:
- You are a senior citizen with a significant corpus (Rs 10L+)
- You are in the 20%+ tax bracket
- You file under old regime (80TTB available)
- You can dedicate Rs 12.2L to SCSS and the rest to PPF extension
Small Finance Bank FDs: The Yield Trap
Unity Small Finance Bank offers 9% for senior citizens. Suryoday SFB offers up to 7.9% for regular depositors. These rates are 200-300 bps above large banks.
But there is a catch: DICGC insurance covers only Rs 5 lakh per depositor per bank — including both principal and accumulated interest.
| Deposit Size | DICGC Coverage | Uninsured Amount | Risk |
|---|---|---|---|
| Rs 5,00,000 | Rs 5,00,000 | Rs 0 | Fully insured |
| Rs 10,00,000 | Rs 5,00,000 | Rs 5,00,000 | 50% at risk |
| Rs 30,00,000 | Rs 5,00,000 | Rs 25,00,000 | 83% at risk |
No small finance bank has defaulted on FDs yet. But “yet” is doing a lot of work in that sentence. The extra 2-3% yield on Rs 25 lakh of uninsured deposit does not price in the tail risk.
If you want SFB rates: Split deposits across 6 different small finance banks at Rs 5L each. Fully insured. Full high-yield benefit. More paperwork, but zero default risk up to the insured limit. See the FD laddering strategy guide for exactly how to build a multi-bank FD ladder with full DICGC coverage.
Decision Matrix: Your Situation, Your Best Instrument
| Your Situation | Best Primary Instrument | Why |
|---|---|---|
| Salaried, 30% bracket, under 40 | PPF | Tax-free compounding over 15+ years; max Rs 2L/year |
| Salaried, 20% bracket, 40-55 | PPF + debt MFs | PPF for tax-free fixed income; debt MFs for liquidity — see how to start SIP and direct vs regular plan fees |
| Retired, 60+, no taxable income | SCSS (max Rs 30L) | Highest rate (8.2%), quarterly income, zero tax impact |
| Retired, 60+, 20-30% bracket | Rs 12.2L SCSS + PPF extension | Split strategy yields 7.55%, zero tax on combined income |
| Emergency fund / short-term | FD laddering | Split across 1-5 year tenures for liquidity + reasonable yield |
| Rs 50L+ corpus, senior citizen | Rs 12.2L SCSS + PPF extension + FD ladder | SCSS for sheltered income, PPF for tax-free growth, FDs for overflow and liquidity |
The Deposit Timing Rule That Adds Free Returns
PPF interest is calculated on the minimum balance between the 5th and last day of each month.
If you deposit Rs 2 lakh on April 6, you earn interest from May. If you deposit it on April 4, you earn interest from April itself.
At 7.1%, one month’s interest on Rs 2 lakh = Rs 1,183. Over 15 years of annual deposits, this timing discipline adds approximately Rs 17,750 in extra interest — for doing nothing differently except depositing 2 days earlier.
Set a reminder: deposit before the 5th of the month. Every month you contribute, every year.
What This Means for Your Money
Stop comparing gross rates. Start comparing post-tax yields at your bracket.
If you are in the 20%+ bracket, PPF’s 7.1% tax-free return beats everything in the sovereign-backed fixed-income space. SCSS looks higher on paper but delivers less after the government takes its share.
If you are a senior citizen, the Rs 12.2 lakh SCSS allocation is the most important number in your financial plan. Get this right, and you pay zero tax on your fixed-income returns while earning 7.55% blended yield.
If you are filing under old regime with SCSS or FD interest, file Form 121 in April 2026. Not later. Not when your CA reminds you. In April.
And if your PPF is maturing — submit Form H now. Not next quarter. Now.
Thinking about “higher return” alternatives like invoice discounting? At the 30% bracket, invoice discounting’s 12% IRR becomes just 8.4% post-tax — only 1.3% above PPF’s 7.1% tax-free, with real default risk and no regulatory protection.
