Ordinary non-speculative business loss can be carried forward for eight tax years and set off against future business/professional profit. Timely filing is generally required to preserve carry-forward.

Legal or Computational Framework

Governing rule

Current-year business loss can be set off against eligible heads other than salary, subject to restrictions. Brought-forward business loss cannot be set off against salary or capital gains and is applied before unabsorbed depreciation.

Correct calculation method

Compute current loss; perform current-year set-off; file the loss return by the due date; maintain origin-year schedule; set off against future business profit before depreciation.

Step-by-step workflow

  1. Compute current loss.
  2. perform current-year set-off.
  3. file the loss return by the due date.
  4. maintain origin-year schedule.
  5. set off against future business profit before depreciation.

Worked example

Business loss ₹6 lakh and house-property income ₹2 lakh allow eligible current-year set-off, leaving ₹4 lakh to carry forward if the return is timely.

The example is an illustration, not a substitute for the taxpayer's facts. A change in status, period, payment mode, document, city, asset, relationship or scheme can change the result.

Why generic pages get this wrong

Search pages often state a rate or limit without identifying the governing base. The calculation must distinguish gross receipt from taxable profit, tax from TDS, a deduction from an exemption, salary from business income, and an accounting entry from the tax treatment.
