Section 33 of Income Tax Act: Development Rebate 

When people hear Section 33 of the Income Tax Act, confusion is very common.

Some say it is about depreciation.
Some link it to development allowance.
Others say it no longer applies at all.

And honestly, all of them are partly right.

Section 33 is one of those provisions that makes sense only when you understand its historical context. It played a very important role in encouraging industrial growth in India—but over time, it was phased out and replaced with more practical tax incentives.

In this article, I’ll explain Section 33 of the Income Tax Act in a clear, non-technical, and real-world manner:

  • What it originally provided
  • Why it existed
  • What “development rebate” really meant
  • How it was replaced
  • And whether it has any relevance today

What Is Section 33 of the Income Tax Act?

Section 33 of the Income Tax Act originally dealt with:

👉 Development rebate (also referred to as development allowance in common language)

In simple terms, it allowed:

  • An additional deduction to businesses
  • For acquiring new machinery or plant
  • Used for business or professional purposes

This deduction was over and above normal depreciation.


The Core Idea Behind Section 33

The government’s thinking was simple:

“If businesses invest in new assets and expand production, the economy grows. Let’s reward that investment through tax benefits.”

So Section 33:

  • Encouraged industrial development
  • Rewarded capital investment
  • Reduced effective tax burden for growing businesses

Development Rebate: What Did It Mean?

Development rebate was a special tax deduction allowed on:

  • Newly installed plant and machinery

It was not the same as depreciation.

Difference Between Depreciation and Development Rebate

Aspect

Depreciation

Development Rebate

Nature

Regular deduction

Incentive deduction

Purpose

Wear and tear

Encourage expansion

Frequency

Every year

One-time benefit

Section

Section 32

Section 33

So, Section 33 did not replace depreciation—it worked alongside it.


Assets Covered Under Section 33

Originally, Section 33:

  • Provided for deduction in respect of tangible and intangible assets
  • Mainly focused on plant and machinery

It did not apply to:

  • Land
  • Buildings (except certain cases)
  • Second-hand machinery

Only new assets qualified.


Conditions for Claiming Development Rebate (Earlier)

To prevent misuse, Section 33 imposed strict conditions:

  • The asset must be new
  • Asset must be used for business
  • A portion of profits had to be transferred to a development rebate reserve
  • The asset could not be sold within a specified period

If conditions were violated, the deduction could be withdrawn.


Why Section 33 Was Introduced in the First Place

Post-independence, India needed:

  • Industrial growth
  • Manufacturing capacity
  • Infrastructure development

Section 33 was a policy tool, not just a tax provision.

It was meant to:

  • Push businesses to modernize.
  • Encourage capital formation
  • Reduce reliance on imports

When Was the Development Rebate Discontinued?

This is a key point many people miss.

👉 The development rebate provision under Section 33 was discontinued after May 31, 1974.

That means:

  • Assets acquired after this date no longer qualified
  • Section 33 stopped operating in its original form

So today, Section 33 is largely of historical relevance.


What Replaced Section 33?

After discontinuing the development rebate, the government introduced:

  • Higher depreciation rates
  • Investment allowance
  • Additional depreciation (later under Section 32)

These newer provisions were

  • Simpler to administer
  • Easier to comply with
  • Better aligned with modern business needs

That’s why many people now confuse Section 33 with depreciation—it influenced what came later.


Is Section 33 Still Applicable Today?

In practical terms:

  • No, Section 33 is not actively used for current assets
  • It applies only to legacy cases where:
    • Assets were acquired before the cutoff date
    • Claims were already in progress

For modern taxpayers:

  • Section 32 (Depreciation)
  • Section 32(1)(iia) (Additional depreciation)

are the relevant provisions.


Why Section 33 Is Still Studied

If it’s discontinued, why does Section 33 still matter?

Because:

  • It explains the evolution of depreciation law
  • It appears in:
    • Exams
    • Academic discussions
    • Old litigation cases

Understanding Section 33 helps you understand why current depreciation rules exist.


Section 33 vs Section 32 (Modern Context)

Many summaries loosely say:

“Section 33 pertains to deduction for depreciation on tangible and intangible assets.”

That statement is conceptually correct but legally outdated.

Today:

  • Section 32 governs depreciation
  • Section 33 historically governed development rebate

But Section 33 laid the groundwork for modern depreciation incentives.


Development Allowance: Is It the Same as Development Rebate?

In common usage:

  • “Development allowance” is often used interchangeably with “development rebate.”

Legally:

  • Section 33 spoke of development rebate
  • Later incentive provisions refined the concept

So when people say:

“Development allowance under Section 33”

They are usually referring to the same historical benefit.


Example to Understand Section 33 (Historical)

Imagine a manufacturing company in 1972:

  • Buys new machinery worth ₹10 lakh
  • Claims normal depreciation
  • Also claims development rebate under Section 33

This:

  • Reduced taxable income significantly
  • Encouraged reinvestment of profits

That’s how Section 33 worked in practice.


Why Development Rebate Was Phased Out

Over time, problems emerged:

  • Complex compliance
  • Reserve maintenance issues
  • Asset sale restrictions
  • Administrative burden

The tax system needed simplification.

So instead of one-time rebates, the law shifted to:

  • Higher depreciation
  • Automatic deductions

Which is what we see today.


Common Misconceptions About Section 33

Let’s clear a few myths:

Section 33 currently allows depreciation
Depreciation is under Section 32

Section 33 applies to all assets
It applied mainly to new plant and machinery

Section 33 is still widely used
It is largely discontinued


Key Takeaways

  • Section 33 of Income Tax Act dealt with development rebate
  • It provided for deduction in respect of tangible and intangible assets, mainly machinery
  • It was introduced to promote industrial growth
  • The development rebate was discontinued after May 31, 1974
  • Section 33 influenced modern depreciation provisions
  • Today, it has mostly historical relevance

Final Thoughts

Section 33 is a reminder that tax law evolves with economic needs.

What once helped build factories and industries later became outdated—and was replaced by more efficient mechanisms. Understanding Section 33 is not about claiming deductions today but about understanding how India’s tax incentives for business growth developed over time.

If you’re a student, this section gives you conceptual clarity.
If you’re a professional, it helps you understand the logic behind modern depreciation law.

And if you’re a business owner, the real takeaway is this:

Tax law doesn’t just collect revenue—it shapes economic behavior.
