Running a business is not just about selling products or offering services; it’s also about managing finances in a way that stays aligned with the law. One of the most misunderstood parts of tax compliance is the list of expenses you cannot claim as deductions.
Section 40(1) of the Income Tax Act outlines specific expenses that are not allowed as deductions while computing income under the head Profits & Gains of Business or Profession. This provision exists to prevent tax avoidance, ensure fairness in the system, and reinforce compliance — especially with Tax Deducted at Source (TDS) obligations.
What Section 40(1) Really Means
At a basic level, Section 40(1) specifies expenses which are not deductible while calculating taxable income. These are amounts the law intentionally disallows, even if the business actually paid them.
The section acts like a “checkpoint” — a filter that ensures only legitimate & compliant expenses are deducted."
This helps maintain the integrity of the tax system while preventing businesses from claiming certain outflows to artificially reduce taxable profits.
Why This Section Exists
Over the years, the government noticed a pattern: some taxpayers claimed expenses but didn’t fulfil basic compliance requirements, especially around TDS or statutory payments.
To prevent misuse, Section 40 was inserted to reinforce discipline. It ensures that tax benefits go only to those who follow the rules.
In short, it promotes:
- Transparency
- Correct reporting
- Fairness in the business ecosystem
- Reduction of loopholes used for tax avoidance

Key Disallowed Expenses Under Section 40(1)
While the Act goes into detailed categories, the spirit of the law remains simple: non-compliant expenses cannot be deducted.
Here are major scenarios where the disallowance applies:
1. Expenses with TDS defaults
If tax was required to be deducted but wasn’t, the related expense becomes disallowed.
This includes payments such as:
- Contractor charges
- Professional fees
- Rent
- Commission
Until TDS is properly deducted & deposited, the deduction remains blocked.
2. Payments that violate statutory provisions
Certain payments that go against legal, regulatory, or ethical standards also fall under disallowance.
For example:
- Penalties for unlawful activity
- Amounts paid in cash violating prescribed limits
These aren’t considered “expenses” in the true sense & thus cannot reduce taxable income.
3. Personal or capital expenses claimed as business expenditure
Some taxpayers inadvertently mix personal and business expenses.
Section 40(1) ensures:
- Personal expenses are not deducted
- Capital expenses remain capitalised & not claimed as revenue expenditure
This distinction keeps financial reporting clean and credible.

A Practical Example
A client once told me, “I’ve paid professional fees to a consultant but forgot to deduct TDS. It’s okay na? I can still claim it?”
And I had to gently remind them: No, not unless you fix the TDS part.
The law is clear — compliance with TDS is directly linked to the deductibility of the expense. Once TDS is deducted & deposited, the deduction becomes allowable in that year or in the year of correction.
This small oversight could have increased their taxable income significantly. Thankfully, awareness saved them from a steep tax bill.
How Section 40(1) Protects Businesses Too
Although it feels restrictive, this provision actually protects honest taxpayers.
It ensures:
- Non-compliant businesses don’t gain an unfair advantage
- Accurate financial statements
- Lower chances of scrutiny & penalties
- Stronger accountability in financial reporting
In a way, it encourages good habits that every business benefits from in the long run.
Tips to Avoid Disallowances
Here are practical steps businesses can follow:
- Track TDS deadlines and deposit on time
- Keep proper invoices and documentation"
- Avoid claiming personal expenses
- Maintain separate accounts for business & personal spending
- Stay updated with changes in tax laws
- Use digital modes for payments wherever possible
- Consult a tax professional for ambiguous cases
These habits significantly reduce errors and help maintain clear books of accounts.
