Included with the book

The tracking spreadsheet

Every reader gets a tracking spreadsheet: one line per transaction, and it keeps your holdings, your average cost, what your portfolio is worth today, and how long you have held each purchase. It then exports the list of your transactions as a plain file, ready for the Schedule VDA section of your return or for handing straight to a chartered accountant. The access code is printed in the book.

Frequently asked questions

From what amount do I pay tax on crypto in India?

There is no exemption threshold in India. The very first rupee of gain on a transfer of a Virtual Digital Asset (VDA) is taxable at 30 %, plus 4 % health and education cess. This is unlike some other countries that have a small-sale allowance.

What is the tax rate on crypto gains in India?

A flat 30 % on the gain from every VDA transfer (sale for rupees, crypto-to-crypto swap, stablecoin conversion, or payment in crypto), plus 4 % health and education cess on the tax, making an effective floor of 31.2 % for most taxpayers. A surcharge applies only above ₹5 crore of total annual income. There is no option to choose the regular slab rates instead.

Is swapping one crypto for another (or into a stablecoin) taxable in India?

Yes. Every transfer of a VDA is a taxable event in India. Swapping Bitcoin for Ethereum, moving into USDT, or paying for goods in crypto all trigger the 30 % tax on any gain. There is no crypto-to-crypto deferral like in some other jurisdictions.

Do I need to file anything if I only held crypto and did not sell?

No capital gain arises without a transfer. However, if you held crypto on a platform based outside India (Binance, Kraken, Coinbase, etc.) at any point during the calendar year (1 January – 31 December), even for a single day and even with no gain, you must declare that account in Schedule FA (Foreign Assets) of your Income Tax Return. Your own wallets (Ledger, MetaMask, etc.) are not accounts held with anyone else and are not reported on Schedule FA.

How much money do I need to start?

A few hundred rupees are enough to learn the gesture. The right amount is one whose total loss would not change your daily life, and it comes after your emergency savings.

Where do I keep my seed phrase (recovery phrase)?

Offline, never in a photo, never in the cloud, never shared with anyone. Paper is enough for learning with small amounts; beyond that, a metal plate resists fire and water.
