If you run a business or practice a profession, you already know how complicated income calculations can get. Between expenses, deductions, depreciation, allowances, and employee benefits, the final “taxable income” never looks like the income you see in your bank account.
Section 29 of the Income Tax Act acts as the starting point — the doorway that guides how income from business or profession is computed. It plays a much bigger role than people realise. Essentially, it states that the income referred to in Section 28 (profits and gains of business or profession) shall be computed in accordance with the provisions contained in Sections 30 to 43D.
In other words, Section 29 is a computational section that deals with how to calculate the ‘Profits and Gains of Business or Profession’ by pointing you toward the detailed rules that follow.
What Exactly Is Section 29 of the Income Tax Act?
Section 29 doesn’t compute anything itself. Instead, it acts like a signpost. It tell us, to understand how income from business or profession profits and gains are computed, you must follow Sections 30 to 43D."
That’s it.
Simple.
But extremely powerful.
It links Section 28 (which defines what business income is) to the deductions, allowances, depreciation rules, & expense provisions laid out later in the Act.
Without this link, the computation of business income would be vague and inconsistent.
Why Section 29 Is So Important
If you think of business taxation like solving a math problem, then:
- Section 28 tells you what numbers to start with.
- Section 29 tells you which rules to apply.
- Sections 30–43D show you how to reach the final answer.
This structure ensures two things:
- Uniformity — every business follows the same rules.
- Fairness — legitimate expenses & deductions are considered.

How Income Is Computed Under Sections 30 to 43D
Section 29 essentially opens the door to these key areas:
1. Rent, repairs, and insurance (Section 30)
Expenses for business premises.
2. Repairs and insurance of machinery/plant (Section 31)
3. Depreciation (Section 32)
One of the most commonly claimed deductions.
4. Scientific research expenditure (Section 35)
5. Deductions related to employee welfare
This is important — Section 29 seeks to provide deductions related to employee welfare through subsequent sections such as:
-
PF and superannuation contributions (36(1)(iv))
-
Bonus & commission payments (36(1)(ii))
-
Medical benefits
-
Leave encashment (subject to rules)
6. Interest, taxes, and other payments (Sections 36 & 37)
7. Special deductions for banking, NBFCs, and insurance sectors
8. Disallowance sections (40, 40A, 43B)
These ensure only legitimate, timely expenses are allowed.
Everything you include or exclude when computing business income comes from these sections.
A Small Real-Life Moment
I remember helping a small manufacturing business with their first tax computation. The owner said, “My income is ₹42 lakh. Will I pay tax on all of it?”
When we applied depreciation, employee welfare deductions, interest on business loans, & rent for factory premises… the taxable income dropped by almost half.
He looked at me, genuinely surprised, and said, “Why doesn’t anyone explain this clearly?”
That’s when I realised how important Section 29 is — it connects every allowed deduction to the final number.
How Section 29 Helps Employers
A lot of employers don’t know this, but Section 29 indirectly allows them to:
- Deduct PF contributions
- Deduct superannuation contributions
- Deduct employee welfare expenses
- Claim benefits for medical & insurance expenses
- Deduct bonus and incentives
Because Sections 36 and 37 fall under the computational range of 30 to 43D, these deductions are allowed because Section 29 points toward them.
This encourages better working conditions — the law rewards employers who care about their people.

How Section 29 Helps Professionals
For professionals (lawyers, doctors, freelancers, consultants), expenses like:
- Office rent
- Internet bills
- Equipment purchases
- Depreciation on laptops
- Staff salaries
- Travel for work
- Repairs & maintenance
…all become deductible through the rules under Section 29’s umbrella.
A graphic designer once told me,
"My laptop is my life — can I claim it?"
And the answer was yes — depreciation under Section 32.
What Section 29 Doesn’t Cover
It’s important to know what Section 29 does not do:
- It does not define business income (Section 28 does that).
- It does not give the actual deductions (Sections 30–43D do).
- It does not compute the final figure on its own.
It simply directs you to the right computation mechanism.
Why Section 29 Matters Even if You’re Not a Tax Expert
Because it ensures:
- You don’t pay tax on gross receipts
- Your legitimate expenses reduce taxable income"
- You understand your true profits
- Every rupee spent on business is accounted for properly
And most importantly:
You only pay tax on your real income — not an inflated number.
