Senior Citizen Savings Scheme vs FD vs RBI Floating Rate Bond: Post-Tax at 60

You retired last month with ₹40 lakh you want to keep safe and income-producing. Every relative has an opinion: “SCSS, 8.2%, government-backed, done.” Someone else swears by the RBI Floating Rate Bond. Your banker is quietly pushing a senior-citizen FD.

The lazy answer is “put it all in SCSS, it pays the most.” You cannot. SCSS caps a single account at ₹30 lakh. So the real question is not “which one” but “what do I do with the ₹10 lakh that will not fit in SCSS, and does the tax on all of it change the ranking?”

The short version: SCSS wins on gross rate and should be maxed first, the overflow belongs in a senior FD (not the RBI bond, at current rates), and for most retirees the whole thing is tax-free anyway because of the new-regime rebate. But the details are where money is made and lost. Let me show the numbers.

The three instruments, side by side

All three are taxed identically - at your income slab, every year, as interest income. None gives you a lower capital-gains rate. So the ranking comes down to gross yield, the cap, the payout timing, and what happens to rates from here.

A note on that 7.35% for the RBI bond. The Floating Rate Savings Bond 2020 pays the NSC rate plus 0.35%, reset every 6 months on 1 January and 1 July. At the July 2026 reset, with NSC at 7.0%, the coupon is 7.35%. That same bond paid 8.05% through 2024-25 when NSC was higher. It floats both ways - remember that, it matters later.

The Rs 30 lakh cap forces the real decision

Since April 2023 the SCSS limit is ₹30 lakh per individual, up from the old ₹15 lakh. That is the single most important number here. Your ₹40 lakh does not fit in one SCSS account, so you have to split it.

There are two clean ways to split, and one of them most people miss:

• Solo: ₹30 lakh in your SCSS + ₹10 lakh in the next-best instrument.
• Couple: if your spouse is also 60+, open ₹30 lakh in your name and ₹10 lakh (or up to ₹30 lakh) in theirs. Two accounts, two ₹30 lakh limits, so a couple can shelter up to ₹60 lakh in SCSS at 8.2%. If that applies to you, stop reading and do that - both of you get the top rate and each gets a separate ₹50,000 TDS threshold and 80TTB deduction.

For the rest of this post I will assume the solo case: ₹30 lakh in SCSS, ₹10 lakh to place. The overflow is a straight fight between the RBI bond and a senior FD.

Gross income: SCSS-max already leads

Three ways to deploy the full ₹40 lakh, annual interest before tax:

The SCSS-max portfolio produces ₹21,000 more per year than an all-FD approach and ₹27,000 more than going all-in on the RBI bond, before a rupee of tax. That gap comes entirely from SCSS’s 0.7-0.85% rate advantage on the first ₹30 lakh. The overflow choice (FD at 7.5% vs bond at 7.35%) is a smaller ₹1,500-a-year decision on the ₹10 lakh.

If your local small finance bank offers a genuinely DICGC-covered senior FD near 8.25%, the overflow FD gets more attractive - but only insure ₹5 lakh per bank, so ₹10 lakh across two such banks keeps you fully covered.

The tax situation of an actual retiree

Here is where most comparisons go wrong: they assume a 30% bracket. Most retirees are nowhere near it.

Under the new tax regime for FY 2025-26, the Section 87A rebate makes total income up to ₹12 lakh completely tax-free. A retiree whose only income is the interest on this ₹40 lakh earns roughly ₹3 lakh a year. That is not just under ₹12 lakh, it is under the ₹4 lakh basic exemption. Tax payable: zero.

So for the large group of retirees living mainly off their fixed-income corpus, the post-tax ranking equals the gross ranking, and it is not close:

If that is you, the tax section is over. Max SCSS, put the overflow in a senior FD, ignore the RBI bond, and submit Form 15H (below) so nobody deducts TDS you will only have to claim back.

The math only gets interesting for retirees with a fat pension, rental income, or a working spouse that pushes total income past ₹12 lakh, so this interest is taxed at the margin. Say the interest lands on top of income already in the 20% or 30% band. Under the new regime there is no 80TTB deduction, so the full interest is taxed:

The order never changes. SCSS-max wins at every bracket because a higher gross rate taxed at the same slab is still a higher net. Tax does not rescue the RBI bond - its lower coupon means it loses on gross and therefore loses on net. The idea that the “floating” bond is somehow more tax-efficient is a myth; it is taxed exactly like the FD, just at a worse rate today.

One lever for the higher-income retiree: the old regime still allows Section 80TTB, a ₹50,000 deduction on interest from deposits (SCSS and bank FDs qualify; the RBI bond does not, because it is not a deposit). At the 30% slab that is worth ₹15,600 a year. But the old regime also loses you the ₹12 lakh rebate and has a lower ₹3 lakh exemption, so only choose it after running both regimes in the ITR utility. For most, the new regime wins outright.

TDS and the 15H limit, done right

TDS is not extra tax - it is advance tax the payer deducts and hands to the government against your PAN. You reconcile it at filing. But for a retiree it can lock up cash you needed for monthly expenses, so manage it.

• SCSS: TDS at 10% once annual interest crosses ₹50,000. On ₹30 lakh at 8.2% you earn ₹2.46 lakh, so TDS applies unless you file 15H.
• RBI Floating Rate Bond: TDS applies on the coupon; the old TDS-free status of these bonds is gone. Crosses the ₹50,000 threshold easily on ₹40 lakh.
• Senior FD: TDS at 10% once interest per bank crosses ₹50,000 in a year (this senior threshold is ₹50,000, versus ₹40,000 for those under 60).

Form 15H is the retiree’s tool. A senior citizen can submit it to stop TDS if their final tax liability for the year is nil. Crucially, under the new regime that means total income up to ₹12 lakh - because the rebate zeroes the tax even though the income is well above the basic exemption. So the nil-tax retiree earning ₹3 lakh of interest is squarely eligible: file 15H at each bank and at the RBI Retail Direct portal in April, and no TDS gets deducted at all.

Two traps:

• 15H is per financial year and per institution. A 15H filed last April does not carry over. Re-file every April, at every bank and for the bond.
• Do not file 15H if your tax liability is actually not nil (income genuinely above ₹12 lakh under the new regime). A false declaration is a punishable offence, and you would only be deferring TDS you owe anyway.

The quarterly cash-flow difference nobody mentions

For a retiree, when the money arrives matters as much as how much. This is the RBI bond’s quiet weakness.

• SCSS pays interest quarterly, on the last working day of each quarter. On ₹30 lakh at 8.2% that is ₹61,500 every three months, like clockwork.
• RBI bond pays only semi-annually, on 1 January and 1 July. On ₹40 lakh at 7.35% that is ₹1,47,000, but only twice a year - nothing in between.
• Senior FD is the most flexible: you can choose monthly, quarterly, or cumulative payout. Monthly payout suits a retiree matching household expenses.

Line up the SCSS-max portfolio’s cash flow (₹30L SCSS quarterly + ₹10L FD on monthly payout) against an all-RBI-bond retiree:

The bond hands you a lump every six months and silence in between. A retiree living off this income then has to park the ₹1.47 lakh in a savings account earning 3% and drip it out themselves. The SCSS-max mix delivers a smoother, near-monthly stream at a higher total. For income-matching, the payout cadence alone is a reason to skip the bond.

When the RBI bond actually earns its place

I have been hard on the bond, so here is the honest case for it. It has one feature the other two lack: the rate floats. If the RBI enters a hiking cycle and small-savings rates climb, the bond resets upward every six months. It paid 8.05% as recently as 2024-25. SCSS and FD lock your rate at booking, so a rising-rate world leaves them behind while the bond keeps up.

So the bond is a bet that rates rise from here. At today’s 7.35% reset it is the worst of the three on both yield and payout timing. If you are convinced rates have bottomed and will climb, a slice in the floating bond hedges that - but you are giving up ~0.85% versus SCSS for the option, and you cannot exit early (see below) to act on it anyway. For most retirees prioritising certainty, that trade is not worth it.

Liquidity and lock-in: read this before you commit

Certainty of income is only useful if you do not need the principal back early.

• SCSS: 5-year term. Premature closure allowed - before 1 year you forfeit interest paid, between 1-2 years a 1.5% penalty on principal, after 2 years a 1% penalty. Reasonable flexibility.
• RBI bond: 7-year lock, and premature exit is barred except for seniors, on an age ladder - a 60-70 year old can exit only after 6 years, 70-80 after 5, and 80+ after 4, each with a penalty of 50% of the last coupon. Effectively illiquid for most of its life. This is the bond’s biggest hidden cost.
• Senior FD: break any time for a 0.5-1% rate penalty. Most flexible of the three, and the reason the FD is the right home for your emergency-accessible overflow.

If there is any chance you need a chunk of the ₹40 lakh back within a few years, weight toward SCSS (accessible after year 2 at low cost) and FD (accessible any time), and keep the near-illiquid RBI bond small or skip it.

Bottom line

For a retiree parking ₹40 lakh in 2026:

• Max SCSS first. ₹30 lakh at 8.2%, quarterly payout, is the best risk-free rate available to you. If your spouse is 60+, open a second ₹30 lakh account in their name and you may not need anything else.
• Put the ₹10 lakh overflow in a senior-citizen FD, not the RBI bond. The FD pays more today (7.5% vs 7.35%), lets you choose monthly payout, and can be broken in an emergency. Spread it across banks if you want full DICGC cover.
• The RBI Floating Rate Bond is a rate-hike bet, not a default. At 7.35% with a 7-year lock and only semi-annual payouts, it loses on yield, cash-flow timing, and liquidity. Buy it only if you specifically want to hedge rising rates and can leave the money untouched.
• Most retirees pay zero tax on all of this thanks to the new-regime ₹12 lakh rebate. If that is you, file Form 15H everywhere in April so no TDS is deducted, and stop worrying about the tax column.
• Higher-income retirees: the ranking does not change - SCSS-max still wins post-tax at every bracket - but check whether the old regime’s 80TTB deduction beats the new regime’s rebate for your numbers.

The naive “just buy the highest-rate thing” instinct is right about SCSS and wrong about the overflow. The ₹30 lakh cap is the whole game, and the RBI bond’s floating headline hides a lower coupon, worse cash flow, and a long lock-in.

Figures here are illustrative, use representative 2026 rates, and are not investment advice. SCSS and small-savings rates are revised quarterly, the RBI bond coupon resets every six months, and FD rates vary by bank. Verify current rates before you invest.
