Calculate my capital gains taxWhat this calculator shows you
Most tax calculators ask you to enter numbers manually. This one reads your actual broker data — so the output reflects your real portfolio, not an estimate.
Your current LTCG and STCG
Exact tax liability based on your actual trades, calculated using the mandatory FIFO method.
How much of the Rs 1.25L exemption remains
See instantly whether you should be booking more gains before year-end — or protecting what's left.
Which positions to sell for loss harvesting
Ranked by tax savings, not just rupee loss amount. STCL vs LTCL correctly distinguished.
Estimated tax saved per action
Specific numbers for each recommended sell. Not vague suggestions — actual rupee impact.
A downloadable PDF report
Share directly with your CA or use for your own records. Covers your full tax position.
How it works
Upload your reports
Export your Tradebook, Holdings, or Tax P&L report from Zerodha Console or Groww. Upload directly — no copy-pasting required.
We calculate your tax position
TaxHarvestLab applies the FIFO method to every transaction and classifies each gain or loss as LTCG, STCG, LTCL, or STCL. It maps your full picture for the current financial year.
Get your recommendations
Based on your current position, the tool identifies specific actions: which stocks to sell for gain harvesting, which to book for loss offset, and which to leave alone.
Execute or share with your CA
Download the PDF report and act on it directly, or hand it to your Chartered Accountant. The output is yours.
Built for DIY investors on Zerodha and Groww
This tool is designed for self-directed equity investors who:
- Trade listed stocks and ETFs on Indian exchanges
- Use Zerodha, Groww, or similar brokers with downloadable reports
- Want to plan their tax before the financial year ends — not after
- Currently rely on spreadsheets or annual CA consultations to understand their tax position
This tool does not provide investment advice. It calculates your tax math and shows the consequences of each action before you take it.
Common questions
Is this the same as my broker's Tax P&L report?
No. Your broker's Tax P&L shows what tax you've already triggered from completed trades. TaxHarvestLab shows your current realized position and what you can still do with unrealized positions before March 31 to reduce it.
Do I need to be a tax expert to use this?
No. The output is plain language: "Sell X shares of [Stock] to save approximately Rs Y in tax." You don't need to know what FIFO means to act on the recommendations.
Is my portfolio data safe?
Your files are processed on our servers to generate the report and are not permanently stored. Nothing is shared with third parties. Sign in with your Google account to access the tool securely.
Is it free?
Yes. Completely free. No subscription, no credit card, no hidden fees.
