Short-term vs long-term capital loss: set-off and carry-forward rules in India 

Given the uncertain nature of financial markets, trading and investing are always characterised by both profits and losses. Just as there is a chance of earning gains, there is also a possibility of incurring losses. Fortunately, Indian tax laws allow taxpayers to set off and carry forward capital losses, thereby reducing their overall tax liability. 

Capital loss arises when a capital asset is sold for a price lower than its purchase price. Based on the holding period of the asset, capital losses are classified as Short-term Capital Loss (STCL) or Long-term Capital Loss (LTCL). This article explains how these losses can be set off, carried forward, and strategically used for tax optimisation.  

Short-term vs. long-term capital loss: Set-off and carry-forward rules

The Indian tax system offers two mechanisms to reduce the impact of capital losses: set-off and carry forward. 

1. Set-off 

Set-off means adjusting a loss against income or gains in the same financial year. This effectively brings down the taxable income and, in turn, lowers tax liability. 

Set-off can be of two types: 

• Intra-head set-off: Losses can be adjusted only against income under the same head. For instance, capital losses can be set off only against capital gains.
• Inter-head set-off: Losses under one head may be adjusted against income from another head, subject to restrictions. For instance, loss from house property can be set off against business income, subject to limits. 

2. Carry forward 

If losses cannot be fully set off in the same financial year due to insufficient gains, they may be carried forward to future years and adjusted later, subject to specific conditions prescribed under the Income Tax Act. 

The golden rules of capital loss set-off 

Here are some essential rules every taxpayer must know: 

1. Intra-head adjustments must be made first before exploring inter-head set-off options.
2. Short-term capital loss can be set off against both Short-term Capital Gains (STCG) and Long-term Capital Gains (LTCG).
3. Long-term capital loss can be set off only against long-term capital gains.
4. Capital losses cannot be set off against income from salary or other non-capital heads.
5. Loss from house property can be set off against other income only to the extent of ₹2 lakh in a financial year.
6. Loss from business or profession cannot be set off against salary income.
7. Speculative business losses can be set off only against speculative business gains.
8. Non-speculative business losses can be set off against other income (except salary) in the same year.
9. No loss can be set off against income from lotteries, races, card games, or any other form of gambling or betting. 

How to carry forward capital losses 

The Income Tax Act allows most capital losses to be carried forward, provided certain conditions are met. 

• STCL and LTCL can be carried forward for eight assessment years and adjusted as per applicable rules.
• Losses from speculative business can be carried forward for four assessment years and set off only against speculative business income.
• Non-speculative business losses can be carried forward for eight assessment years, but can be set off only against business income.
• Loss from house property can be carried forward for eight assessment years, but can be set off only against income from house property in subsequent years.  

Important note: You must file your Income Tax Return (ITR) on or before the due date under Section 139 (1) to be able to carry forward losses. However, there is one exemption. Loss under the head ‘House Property’ can be carried forward even if a belated return under Section 139 (4) is filed. 

Tax-loss harvesting: Portfolio red into tax green 

Tax loss harvesting is an effective technique for reducing tax liability. It involves selling underperforming assets to realise losses and use them to offset capital gains. 

Steps involved: 

1. Review your portfolio to identify underperforming assets.
2. Sell those assets to book capital losses.
3. Offset the losses against capital gains earned in the same year.

Example:  

• STCG from listed equity shares: ₹5,00,000
• LTCG from listed equity shares: ₹20,00,000
• STCL on selling an underperforming stock: ₹1,00,000 

Bottom line: Tax-loss harvesting reduced the overall tax liability by ₹20,000.

Key differences: short-term vs long-term capital loss 

*Holding period varies by asset class.

Common pitfalls to avoid 

To maximise the benefit of set-off and carry forward rules, avoid these mistakes: 

• Missing the ITR filing deadline
• Not classifying STCL and LTCL accurately
• Not maintaining clear purchase and sale records
• Ignoring small losses that can add up
• Not keeping a track of carry-forward periods and expiry timelines
• Not seeking professional advice when needed 

Conclusion

Set-off and carry-forward rules are powerful tools for reducing tax liability when used correctly. Understanding the conditions and using strategic tools like tax loss harvesting can significantly improve post-tax investment returns.
