Expenses Disallowed and Amounts Not Deductible (CA Final DT)
Updated 5 October 2026 · Fact-checked
Disallowed expenses are business costs you cannot deduct, or can deduct only later, because the law restricts them. To solve a question, test each expense for cash payment above the limit, TDS default, excess payment to a related person, or non-payment by the due date. Then add back the disallowed amount to the profit.
Understand Expenses Disallowed and Amounts Not Deductible
Business income is computed after deducting expenses that are incurred wholly and exclusively for the business. But the law places extra conditions on certain expenses. If you fail the condition, the expense is disallowed: you add it back to the profit shown in the books.
There are two kinds of disallowance. The first is permanent. The expense is never allowed, for example a cash payment above the limit. The second is timing. The expense is allowed, but only in the year you actually pay it, for example bonus or statutory dues paid late. A timing disallowance is added back this year and deducted in the year of payment.
The law uses these conditions as controls. Cash limits push you towards banking channels, so payments leave a trail. TDS-default rules push you to deduct and deposit tax. Related-person rules stop you from inflating payments to relatives or connected persons. Payment-basis rules stop you from claiming dues that you have only provided for in your books.
The exam approach is mechanical. Go through the expense list line by line. Ask which condition applies, whether it was met, and what amount is disallowed. Then decide whether the disallowance is permanent or only deferred. Most marks are lost by missing the year in which a deferred item becomes allowable.
Work on the tax year 2026-27 under the Income-tax Act, 2025. Quote the provision by its subject (cash payment, TDS default, and so on) unless the paper text gives you the section number.
Key rules to remember
- Cash payment disallowance
- Expenditure (including a purchase of goods) for which payment to one person in one day > ₹10,000 is made otherwise than by account payee cheque/draft, bank electronic mode or other prescribed mode → whole expenditure disallowed
- The rule applies to the expenditure incurred for which the payment is made, so it covers purchases and expenses alike, as long as the cost was debited to profit. Check how the purchase was debited. If it was routed through the trading account or stock, the disallowance still applies to that expenditure, so make the adjustment in the profit or stock figure. The limit is ₹35,000 per day for payment to a transporter for hiring goods carriage. The test is per person per day, not per year. Prescribed exceptions exist, such as payments to banks and the Government.
- TDS default on payment to a resident
- Disallowance = 30% × specified resident payment (such as interest, commission or brokerage, fees for professional or technical services, rent, contract payments), where tax was deductible but not deducted, or deducted but not deposited by the due date for filing the return
- The 30% rule applies only to the specified payments to residents, not to every expense. The 30% disallowed is allowed in the year of deposit of the tax. This holds in both cases: the tax is deducted in a later year, or it was deducted in the year of expense and deposited after the return due date. No disallowance applies if the payee has paid the tax and furnished the required certificate.
- TDS default on payment to a non-resident
- Disallowance = 100% × expense, where the sum is paid to a non-resident (or outside India), is chargeable to tax in India, and tax was deductible but not deducted, or deducted but not deposited by the due date for filing the return
- Applies to interest, royalty, fees for technical services and other sums chargeable to tax in India. The trigger is that the sum is chargeable in India and tax was deductible on it. The expense is allowed in the year of deposit of the tax, both where the tax is deducted in a later year and where it was deducted in the year of expense and deposited after the return due date.
- Payment-basis items with return-due-date relief
- Allowed in the year of provision only if actually paid on or before the due date for filing the return; otherwise allowed in the year of actual payment
- Covers statutory dues like tax, duty, cess and fee (the liability itself must actually be paid by the return due date; a mere provision is not enough); employer's own contribution to PF/ESI and similar funds; bonus or commission to employees; and interest on loans from specified banks and institutions. For this interest, actual payment by the return due date is needed. Converting unpaid interest into a loan or borrowing is not treated as payment, so it stays disallowed until actually paid. The conditions differ for each item, so check each one. Employee's contribution is not in this group; see the next rows.
- Payment-basis items with no return-due-date relief
- Leave encashment: allowed only in the year of actual payment. Sums owed to micro and small enterprises beyond the permitted period (15 or 45 days, as applicable): disallowed in the year of expense and allowed only in the year of actual payment
- Paying these after the year-end but before the return due date does not bring the deduction back into the year of provision. Do not group them with bonus or statutory dues.
- Employee's contribution
- Allowed only if deposited within the due date under the relevant Act, which is stricter than the return due date
- Employer's own contribution is different: it is allowed if deposited by the due date for filing the return. Do not apply one date to both.
- Related person payments
- Disallowed = Amount paid − Amount that would be reasonable as per fair market value or the business need
- Only the excess or unreasonable part is disallowed. Apply it to an expense paid to a related person, as defined, for goods, services or facilities.
- Other amounts not deductible
- Income-tax and its surcharge or cess, and fines or penalties for breach of law: not deductible
- Do not confuse these with allowable business levies such as GST on inputs, which follow their own treatment.
How to solve Expenses Disallowed and Amounts Not Deductible questions
Use this method for any question that gives a profit figure and a list of expenses and asks for business income or the disallowance.
- 1Note the starting figure. Check whether the listed expenses were already debited to the profit and loss account. Add back only what was debited.
- 2Go through each expense in order. Ask which category it falls in: cash payment, TDS default, related person, payment-basis item, or an ordinary allowable expense.
- 3For cash payments, apply the rule to the expenditure (including a purchase of goods) for which the payment was made. Check the per-person, per-day total, the mode of payment and the limit (₹10,000, or ₹35,000 for transporters). If it fails, add back the whole expenditure that was paid for.
- 4For TDS, check whether tax was deductible, whether it was deducted, when it was deposited, and whether the payee is a resident (30%) or non-resident (100%).
- 5For payment-basis items, find the payment date. Compare it with the required date (the return due date or the due date under the specific law). Add back what was unpaid. For leave encashment and overdue micro and small enterprise dues, only actual payment counts. For interest on loans from specified banks and institutions, converting unpaid interest into a loan is not payment.
- 6For related persons, compare the amount with a reasonable or fair market amount. Add back only the excess.
- 7Total the add-backs and state which are permanent and which are allowed in a later year, naming that year.
- 8Present the final computation clearly and note any assumption, such as the return due date.
Quickest way: Three-question screen per expense
When to use it: Use it when a question lists many expenses and you have only a few minutes.
- Question 1: Was it paid in cash above the daily limit to one person? If yes, disallow the full amount.
- Question 2: Was tax deductible on it, and was it deducted and deposited in time? If not, disallow 30% for a resident, 100% for a non-resident.
- Question 3: Is it a payment-basis item or a payment to a related person? If yes, check the payment date or the reasonableness.
- Tick each expense as 'clean' or note the add-back beside it. Add the amounts at the end and mark any item that becomes allowable next year.
Common mistakes in Expenses Disallowed and Amounts Not Deductible
Applying 30% to a payment to a non-resident where TDS was not deducted.
Students remember '30%' as the TDS-default rule and apply it to every payee.
Fix: Look at the residential status of the payee first. The 30% rate is for residents. For non-residents the whole amount is disallowed.
Testing the cash limit on the annual total or on each bill instead of per person per day.
The question gives several payments, and students either add them all up or treat each separately.
Fix: Group payments by person and by date. Add up the same-day payments to that one person and compare with the limit. Payments to different persons or on different days are not added.
Disallowing a timing item permanently.
Students stop after adding back the amount and forget that it is deductible when paid.
Fix: For payment-basis items and TDS defaults, state the year in which the deduction will be available once the payment or deposit is made.
Disallowing only the amount of TDS that was not deducted, rather than the expense.
The words 'non-deduction of tax' make students think of the tax amount.
Fix: The disallowance is a percentage of the expense on which tax was deductible, not the tax itself.
Disallowing the whole payment to a related person.
Students treat any related-party payment as suspect.
Fix: Disallow only the part that is excessive or unreasonable compared with the fair market value or business need. If it is reasonable, nothing is disallowed.
Adding back an expense that was never debited to the profit and loss account.
Students apply the rule mechanically without checking how the books treated the item.
Fix: Start every add-back with the question: was this charged to profit? If not, there is nothing to add back.
Worked examples
Example 1
For tax year 2026-27, Ravi Traders Pvt. Ltd. shows a net profit of ₹12,00,000 after charging the following: (a) professional fees of ₹5,00,000 to a resident consultant, on which tax was deductible but not deducted, and the payee has not paid the tax; (b) goods purchased for ₹45,000 from one supplier, paid in cash on a single day; (c) cash payments of ₹9,000 each on the same day to two different suppliers; (d) bonus of ₹2,00,000 to employees, provided in the books and paid on 20 December 2027, after the return due date of 31 October 2027. Compute the profit after the necessary adjustments, ignoring all other items.
Show the solution
- Item (a): tax was deductible on a payment to a resident but was not deducted, so 30% of ₹5,00,000 is disallowed = ₹1,50,000.
- Item (b): ₹45,000 was paid in cash to one person on one day, which exceeds ₹10,000. The question states that the purchase was charged to profit, so the whole ₹45,000 is disallowed. If a purchase is routed through the trading account or stock, the disallowance still applies to that expenditure and you adjust the profit or stock figure accordingly.
- Item (c): the payments are to two different persons, and each is ₹9,000, which is within the ₹10,000 limit. Nothing is disallowed.
- Item (d): bonus is allowed in the year of provision only if paid on or before the return due date, which is 31 October 2027. It was paid on 20 December 2027, after that date, so the full ₹2,00,000 is disallowed in tax year 2026-27. It is allowed in tax year 2027-28, the year of payment.
- Total add-backs = ₹1,50,000 + ₹45,000 + ₹2,00,000 = ₹3,95,000.
- Adjusted profit = ₹12,00,000 + ₹3,95,000 = ₹15,95,000.
Answer: Profit after adjustments is ₹15,95,000. Add-backs are ₹1,50,000 (TDS default), ₹45,000 (cash payment) and ₹2,00,000 (bonus). The bonus is deductible in tax year 2027-28, the year of payment. The ₹1,50,000 is allowed only in the year the tax is deposited. The ₹45,000 cash payment is never allowed.
Example 2
Meera Exports Ltd. debited ₹4,00,000 of interest to a lender for tax year 2026-27. Tax was deductible on it, and was deducted on 31 January 2027 but deposited only on 15 November 2027. Assume the due date for filing the return is 31 October 2027, and that the interest is chargeable to tax in India even if the lender is a non-resident. What is the disallowance for tax year 2026-27 if the lender is (i) a non-resident, and (ii) a resident? In which year is the amount allowed?
Show the solution
- Tax was deducted in tax year 2026-27, but the deposit on 15 November 2027 is after the return due date of 31 October 2027.
- So the TDS condition is not met for tax year 2026-27, and the disallowance applies.
- Case (i), non-resident: the interest is a sum chargeable in India on which tax was deductible, so the whole expense is disallowed = ₹4,00,000.
- Case (ii), resident: interest is a specified payment, so 30% of the expense is disallowed = 30% × ₹4,00,000 = ₹1,20,000.
- Year of allowance: here the tax was deducted in the year of expense and deposited after the return due date. In this case, as where tax is deducted in a later year, the disallowed amount is allowed in the tax year in which the tax is deposited. The deposit on 15 November 2027 falls in tax year 2027-28 (1 April 2027 to 31 March 2028).
- So ₹4,00,000 (non-resident) or ₹1,20,000 (resident) is deductible in tax year 2027-28.
Answer: Disallowance in tax year 2026-27 is ₹4,00,000 if the lender is a non-resident and ₹1,20,000 if a resident. Each amount is allowed in tax year 2027-28, the year in which the tax is deposited.
Exam tips
- In the written answer, show the expense, the rule, the test applied and the amount disallowed, one line per item. This follows the provision-facts-conclusion pattern and earns step marks even if one figure is wrong.
- State your assumptions plainly, for example the return due date or that the expense was debited to profit. Examiners accept reasonable stated assumptions.
- For case-scenario MCQs, read dates and payee status first. The trap is usually the payee (resident or non-resident), the mode of payment or a single day of payment. There is no negative marking, so always attempt.
- Always say when a deferred item becomes allowable. This is a separate mark in many answers.
- Do not quote old Act section numbers. Name the rule by its subject, and quote a 2025 Act section only if your paper text gives it.

Expenses Disallowed and Amounts Not Deductible: frequently asked questions
What is the cash payment disallowance limit for CA Final DT?
The rule applies to expenditure, including purchases, for which payment to one person in one day exceeds ₹10,000 and is not made by account payee cheque, draft or a permitted electronic mode. The whole expenditure paid for is then disallowed. For payment to a transporter for goods carriage the limit is ₹35,000 per day. Some prescribed payments are exempt from the rule.
What is the 30% disallowance for TDS default?
If tax was deductible on a specified payment to a resident (such as interest, commission, professional or contract fees, or rent) but was not deducted, or was deducted but not deposited by the return due date, 30% of that expense is disallowed. The 30% is allowed in the year in which the tax is deposited. For sums chargeable to tax in India paid to a non-resident, the disallowance is 100%, and it is also allowed in the year of deposit.
What is the difference between disallowance and deduction on payment basis?
A permanent disallowance means the expense is never allowed, such as a cash payment above the limit. A payment-basis item is allowed, but only in the year you actually pay it, such as bonus or statutory dues. So it is added back now and deducted later.
Are payments to relatives always disallowed?
No. Only the part of a payment to a related person that is excessive or unreasonable, judged against fair market value or the business need, is disallowed. A reasonable payment is allowed as usual.
