Fixed deposits and debt mutual funds are both relatively safe, fixed-income options — and after recent changes, both are largely taxed at your slab. But how and when the tax applies differs. Here's the comparison.

Quick answer
Both fixed-deposit interest and debt-fund gains are now taxed at your slab, but the timing of the tax differs. Here's the comparison.
Interest on a fixed deposit is taxable at your slab rate, and it's taxed as it accrues each year — whether or not you withdraw it. So you pay tax annually on FD interest, and the bank may deduct TDS along the way.
Gains on debt mutual funds are generally taxed at your slab rate, without the long-term capital-gains concession that equity funds get. So in rate terms, debt funds and FDs are now broadly similar — both ultimately taxed at your slab.
The key difference is timing: FD interest is taxed every year as it accrues, while debt-fund gains are taxed only when you redeem the units. That deferral can be useful — you control the year of redemption, and can choose a lower-income year to realise the gain.
Banks deduct TDS on FD interest above the threshold; debt-fund redemptions are reported in your AIS. Either way, reconcile against your AIS and report fully — FD interest is a common omission since it isn't "received" until maturity.
FDs offer guaranteed returns and simplicity; debt funds offer the tax-timing flexibility of redemption-based taxation and potentially better post-cost returns, with slightly more variability. Choose by your need for certainty versus flexibility — and remember both are taxed at your slab.
Broadly yes in rate terms — both are generally taxed at your slab , as debt funds no longer get the long-term concession. The main difference is timing: FD interest is taxed yearly, debt-fund gains only on redemption.
Every year as it accrues, whether or not you withdraw it — at your slab rate, often with TDS deducted by the bank. It's a common omission since it isn't received until maturity.
Debt funds offer tax-timing flexibility — gains are taxed only on redemption, so you can choose a lower-income year — while FDs are taxed annually. Both are ultimately taxed at your slab.
