Understanding Income Tax Loss Setoff and Carry Forward
Income tax laws provide a facility called "loss setoff" and "carry forward" to help taxpayers adjust losses against income to reduce tax liabilities. This means if you incur a loss under specific heads of income, you can offset that loss against income from other sources or carry it forward to future years to save tax.
Types of Losses and Setoff Rules
-
House Property Loss:
Loss from house property can only be adjusted against income from house property. It can be carried forward for up to 8 years if not fully adjusted in the loss year. Timely filing of Income Tax Return (ITR) is mandatory to carry forward the loss. -
Speculative Business Loss:
This loss is only set off against speculative business income. It can be carried forward for 4 years and again timely filing is required. -
Non-Speculative Business Loss:
Losses from regular business activities can be set off against any other head of income, except salary. If not fully adjusted, they can be carried forward for 8 years and only when the return is filed on time. -
Capital Loss:
Capital losses are of two types—short term and long term. Short-term capital loss can be set off against any capital gain (short or long term), whereas long-term capital loss can only be set off against long-term capital gains. Both can be carried forward for 8 years.
Importance of Filing ITR on Time
Filing the income tax return before the due date is important to be eligible for carrying forward losses. If the return is filed late, the benefit of carry forward may be lost, resulting in paying higher tax.
