It is, of course, not only sunshine & roses running a business in India. Small size units frequently encounter unforeseen disturbances on account of natural calamities, political turmoil, or government initiative. For the purpose of providing financial solace to such concerns, Section 33B is laid down in the Income Tax Act, 1961.

This section details relief or allowance in rehabilitation in particular cases. In brief, it permits impacted businesses to take a special deduction when their enterprise is destroyed, damaged or made unusable. This is an important provision especially for the small businesses which constitute the backbone of the Indian economy.


What is Section 33B of the Income Tax Act?

Rehabilitation allowance in certain cases – Section 33B provides for rehabilitation allowance, where an industrial undertaking, business or profession is discontinued on account of damages caused by floods, cyclones, riots, fires and accidents.

This section provides that if an enterprise is recommenced or re-established within a prescribed period, it would be entitled to rehabilitation allowance. This allowance is considered as an expenditure in calculating the taxable income & as such lessens the tax liability during the period of revival.

This subsidy promotes reconstruction of small unitsindustrial ventures rather than winding them up after loss.


Conditions for Claiming Rehabilitation Allowance

For eligibility to the benefits under Section 33B of Income Tax Act, 1961:

  • The business must have been suspended because of catastrophe, riot, flood, fire, explosion or government request.
  • The project must be re-established, re-built, or resumed within three years after being abandoned.
  • You can only claim the rehabilitation allowance in the year you re-establish."
  • The claim has to be backed up by evidenceverified accounts.

These restrictions ensure that only bona fide entities confronted with actual adversity benefit.

How Rehabilitation Allowance Works

Imagine a small textile unit in Gujarat was washed away by a flood in 2022. The unit had to be shut down, but resumed operations in 2024 after rebuilding.

For the purposes of Section 33B, the unit qualifies for a deduction for rehabilitation allowance in the year it is reinstated (2024–25). This deduction results in less taxable income, providing financial breathing room as it gets back on its feet.

Hence, the rehabilitation allowance is a tax palliative stimulus for resuming but not renouncing the business.


Benefits to Small Scale Units

Small scale units are the main beneficiaries of Section 33B.

Relief under this section:

  • Reduces immediate tax liability.
  • Encourages reinvestment in infrastructure.
  • Gives business owners peace of mind.
  • Protects jobs dependent on these units.

The rehabilitation allowance under Section 33B of the Income Tax Act, 1961 is to support Small Scale Industries as a financial crutch to bounce back.


What Section 33B Allotments are Permissible?

The law is clear – small scale units & others fulfilling eligibility conditions are given rehabilitation allowance under Section 33B.

This deduction is the lesser of either 60% of amount invested to re-start the business or certain limitations. It can be claimed only once, in the year of resumption.

It’s essentially a one-off tax break meant to lessen the pain for businesses hit by calamity.
