A recurring deposit and a SIP (Systematic Investment Plan) look structurally identical — both involve depositing a fixed amount monthly and receiving a return over time — but the return mechanisms, risk profiles, and appropriate use cases are fundamentally different, and confusing them leads to choosing the wrong instrument for the goal
The previous articles on this site covered RD maturity calculation, building savings goals with RDs, RDs vs SIPs vs savings accounts, the quarterly compounding formula, and RDs vs paying down debt. This article addresses RD in the context of tax efficiency — specifically how RD interest is taxed, the implications for net returns, and how to evaluate an RD against post-tax alternatives.
How RD interest is taxed in India
RD interest is taxable as income — it's added to the depositor's total income for the financial year and taxed at the applicable income tax slab rate, not at a preferential capital gains rate.
TDS on RD interest:
- Banks deduct TDS (Tax Deducted at Source) at 10% if the aggregate interest from all deposits with that bank exceeds ₹40,000 in a financial year (₹50,000 for senior citizens, FY2024-25 threshold)
- If total income is below the taxable threshold, Form 15G (under 60 years) or Form 15H (60+) can be submitted to the bank to avoid TDS deduction
- TDS is not the final tax liability — if the depositor's slab rate is 30%, they owe 30% on the interest, with the 10% TDS credited; if slab rate is below 10%, the excess TDS is refunded via ITR filing
Practical example:
- Monthly RD deposit: ₹10,000 for 5 years at 7% p.a. (quarterly compounding)
- Maturity amount: approximately ₹7,18,000 (principal ₹6,00,000 + interest ~₹1,18,000)
- For a 30% slab taxpayer: tax on ₹1,18,000 = ₹35,400 → net interest after tax: ₹82,600
- Effective post-tax annual return: approximately 4.9% (on the invested amount)
Post-tax return comparison: RD vs alternatives
The post-tax RD return depends heavily on the depositor's income tax slab:
| Slab rate | Pre-tax RD return | Post-tax RD return |
|---|---|---|
| Nil (below threshold) | 7% | 7.0% |
| 5% | 7% | 6.65% |
| 20% | 7% | 5.6% |
| 30% | 7% | 4.9% |
Comparison with alternatives:
- PPF (Public Provident Fund): EEE exempt (contributions deductible, returns tax-free, maturity tax-free). Current rate ~7.1% p.a. → 7.1% post-tax for all slab rates. Better than RD for high-slab taxpayers at the same nominal rate.
- Sukanya Samriddhi Yojana (SSY): similarly EEE exempt at ~8.2% → 8.2% post-tax. Restricted to girl children (account holder).
- Equity mutual fund SIP (long-term): returns are taxable as Long-Term Capital Gains (LTCG) at 10% (above ₹1 lakh exempt). Higher potential returns but with equity risk.
- Liquid funds: short-duration debt funds, returns taxed as STCG/LTCG depending on holding period; post-tax efficiency comparable to RD at high slabs.
For high-slab taxpayers with long time horizons, PPF or SSY offer better post-tax returns than RD at similar nominal rates — with the tradeoff of lower liquidity (PPF has 15-year lock-in with limited partial withdrawal provisions).
Why RD still makes sense despite tax drag
Despite the tax efficiency gap, RDs remain appropriate for specific use cases:
Short-to-medium term goals (1-5 years): PPF's 15-year lock-in makes it unsuitable for goals within 5 years. An RD for a down payment, home renovation, or car purchase keeps funds accessible on the exact required date.
Emergency fund laddering: splitting emergency fund across multiple RDs with staggered maturity dates provides both the guaranteed capital (unlike equity) and the scheduled liquidity without sacrificing too much return to a completely liquid savings account.
Capital preservation requirement: for amounts where capital loss is unacceptable (unlike equity investments), the guaranteed maturity amount of an RD provides certainty that PPF's sovereign guarantee also provides — but with shorter tenures.
Senior citizens: higher TDS exemption threshold (₹50,000) and senior citizen rate premiums (typically 0.25-0.5% higher than regular rates at most banks) improve RD's relative attractiveness for this segment.
Comparing across bank rates: the spread matters
Different banks offer different RD rates, and the spread is meaningful in compound terms:
- SBI regular RD rate (2024): approximately 6.5-7.0% for 1-5 year terms
- Small finance banks (AU, Ujjivan, Jana): often 7.5-8.5% for similar tenures
- Post Office RD: 6.7% for 5-year term (backed by Government of India)
DICGC insurance: deposits up to ₹5 lakh per depositor per bank are insured by DICGC (Deposit Insurance and Credit Guarantee Corporation). Small finance banks and cooperative banks carry somewhat higher risk than PSU banks — the higher rate represents a risk premium, though within the ₹5 lakh DICGC limit, the practical risk is minimal.
How to use the RD Calculator on sadiqbd.com
- Calculate maturity amount and total interest for your planned deposit amount, tenure, and bank's offered rate
- Apply your tax slab to the interest component to find post-tax interest — multiply the calculated interest by (1 − your slab rate) for the net after-tax figure
- Compare post-tax RD return against PPF or SSY rates if your investment horizon is 5+ years — the tax efficiency gap may favor the 80C-eligible alternatives at similar nominal rates
Frequently Asked Questions
If I have multiple RDs at the same bank, does TDS apply on each separately or on the total? TDS is calculated on the aggregate interest from all deposits at the same bank in a financial year. If you have five RDs each earning ₹9,000 interest annually, the aggregate ₹45,000 exceeds the ₹40,000 threshold and TDS applies on the total. Spreading deposits across multiple banks doesn't help within TDS threshold calculation — each bank calculates independently across all your deposits at that bank, so the threshold applies per-bank. Spreading across banks (e.g., ₹20,000 interest at Bank A, ₹20,000 at Bank B) keeps each below the threshold, with no TDS at either, if each bank's total stays under the limit.
