Tax harvesting before March 31, 2026? Watch these three hidden costs that can reduce your tax savings

You can reduce your income tax by using tax gain harvesting and loss harvesting, but before you dive into these methods, it’s important to evaluate the costs involved. When we talk about the cost, we are referring to the direct expenses you’ll face when you sell and buy equity assets as part of these harvesting strategies (both gains and losses).

With tax gains harvesting, you can save up to Rs 15,625 in income tax if your long term capital gains (LTCG) are up to Rs 1.25 lakh. This approach is based on a simple principle that if you sell your listed equity shares and equity mutual funds after holding them after holding over than 12 months, then long-term gains from that sale are tax exempt up to Rs 1.25 lakh.

So, in tax gains harvesting, you sell your listed equity shares and equity-oriented mutual funds that have gained value, up to the limit, allowing you to realize Rs 1.25 lakh in long-term profit. After booking that profit, it’s crucial to buy back the same fund or listed shares to keep your financial strategy intact. Just keep in mind that doing this can also increase your acquisition cost, which can be helpful in later years when you sell the asset.


Tax-loss harvesting is a different ball-game. It refers to the practice of reviewing the portfolio and selling identified investments that are currently at a loss to offset capital gains realised during the financial year. To use the tax-loss harvesting process, you need to sell the listed shares and equity mutual funds that are in loss and then repurchase them. By doing so, you can reduce the overall tax liability since capital losses can be set off against capital gains under the provisions of the Income-Tax Act, 1961.

Suppose an investor has the following investments:

Investments in shares	Gain/(Loss)
Stock A	50,000
Stock B	(20,000)

Particulars	Without Tax Loss Harvesting (in Rs)	With Tax Loss Harvesting (in Rs)
Short-Term Capital Gain on Stock A	50,000	50,000
Short-Term Capital Loss on Stock B	–	(20,000)
NetTaxable Short-Term Capital Gains	50,000	30,000
TaxRate (STCG)	20%	20%
Tax Liability	10,000	6,000
Tax Saved	–	4,000

Hidden charges to watch out for

Many investors focus on headline tax-saving instruments and deductions but often overlook the hidden costs that can silently erode post-tax returns. Chartered Accountant Suresh Surana says that these charges may not be immediately visible, but they materially impact the effectiveness of any tax-saving strategy over the long term. Some of the key ones to watch out for include:

Hidden Charge / Cost	Where It Applies	Detailed Impact on Tax-Saving Strategy
Securities Transaction Tax (STT)	Equity shares, equity mutual funds	STT is levied on every buy/sell transaction and cannot be claimed as a deduction or set-off. While individually small, frequent trading or portfolio churn leads to cumulative outflow, directly reducing net returns and undermining long-term tax-efficient compounding.
Stamp Duty & Transaction Charges	Mutual fund purchases, equity trades	Stamp duty and brokerage/transaction fees may seem negligible per transaction, but over multiple investments they add up, increasing the cost base and lowering net returns.
Exit Load	Mutual funds (including ELSS)	Exit loads (typically up to 1% if redeemed early) penalise premature withdrawals. Investors exiting before optimal holding periods not only lose potential tax-efficient gains but also incur this additional cost, reducing effective returns.

In simple terms, an investment should not be judged only by the tax it helps you save, but by how much money you retain after accounting for all taxes and costs. Many investments come with hidden charges, so it’s important to be aware of them and avoid frequent buying and selling.

Surana says: “A good strategy is not just about picking the right tax-saving products, but also understanding their costs, how they work, and any exit conditions. Keeping these costs low can help you grow your wealth more effectively over time.”
