TAX LOSS HARVESTING: ONE USE OF A BOOKED LOSS

Setting off a loss against a gain, and its rules

Published by The Retail Trader · JUL 25, 2026 · Features

Some positions in a portfolio are at a loss and some are in profit. Booking those losses and setting them off against gains is legitimate planning, not a loophole.

THE SET-OFF FRAMEWORK

Capital losses made within a year can be set off against capital gains of the same year, with certain rules on which loss can go against which gain.

A loss that is not set off that year can often be carried forward — but for that, it is necessary to file the return on time.

THINGS TO KEEP IN MIND

These points keep this exercise from going wrong:
• Do this only when that position is worth selling anyway — the tax is the tail, not the dog.
• If you sell and buy back immediately, charges apply both times.
• For carry forward, the return filing timeline matters.
• Rules and limits change — confirm the final calculation only with a CA or an official source.

A PRACTICAL POINT

The biggest benefit is often not tax but cleanup. This exercise forces you to look at positions you had been ignoring for years — and often many of them should have been let go anyway.
