Section 43B of the Income Tax Act is a provision that governs how certain business expenses are treated for tax deduction purposes. It impacts how MSMEs (Micro, Small, and Medium Enterprises) manage their payments and financial records. This section allows deductions for certain statutory expenses only when they are actually paid, regardless of the year they were incurred.
In this article, we’ll break down what Section 43B entails, how it works in practice, and why it holds particular significance for MSMEs.
The Union Budget 2024 introduced a key update to Section 43B through clause 43B(h), aimed at improving MSME cash flow.
This provision encourages businesses to pay MSMEs on time and helps small enterprises maintain healthier working capital. The amendment is applicable from FY 2024-25 onwards.
Section 43B of the Income Tax Act, 1961 falls under the category of "Income from Business and Profession". It ensures certain expenses are allowed as deductions only when they are paid and not merely when they accrue.
This helps in creating transparency and promotes prompt settlement of dues, particularly for MSMEs. For example:
This provision is especially important for enterprises seeking a business or MSME loan, as timely tax compliance and clear financial records can significantly improve loan eligibility and creditworthiness.

Here are some key deductions allowed only on actual payment under Section 43B:
Failure to comply with these timelines results in such expenses being disallowed under Section 43B of the Income Tax Act, meaning the deduction will be deferred to the financial year in which the payment is actually made.
A taxpayer can claim deductions under Section 43B only if they meet specific conditions while following the accrual system of accounting:
Here are the basic conditions to claim deductions:
Section 43B of the Income Tax Act significantly influences how businesses plan their cash flow and manage liabilities. Since certain expenses are allowed as deductions only when actually paid, businesses must prioritise timely payments to optimise tax benefits.
This creates a need for disciplined financial management, especially during peak expense cycles or when facing delayed receivables. In such situations, taking a business loan can be a strategic move. It helps ensure that statutory dues and other eligible expenses are settled within the required timelines, preserving your ability to claim deductions in the same financial year.
Moreover, eligible enterprises with strong creditworthiness can avail of competitive business loan interest rates, which help lower the overall cost of borrowing and redirect more funds towards their core operations or future growth.
Section 43B of the Income Tax Act encourages responsible financial behaviour by allowing deductions only upon actual payments. With the introduction of Section 43B(h), timely payments to micro and small enterprises have become even more important for businesses seeking to maximise tax benefits and avoid deduction delays. For MSMEs, timely payment of statutory dues and employee benefits helps in maintaining cash flow, staying tax compliant, and improving eligibility for external funding.

Section 43B of the Income Tax Act allows deductions for specific expenses only when they are actually paid. These include statutory dues, taxes, employee contributions, and loan interest. It promotes timely payments and accurate financial reporting, especially relevant for MSMEs managing cash flow.
43B disallowance refers to the rejection of deductions for expenses if not paid within the prescribed timeline. Such disallowed expenses under Section 43B of the Income Tax Act may include GST, PF, or interest payments, which must be settled to claim tax benefits.
The 2024 amendment introduced Section 43B(h) of the Income Tax Act, requiring payments to MSMEs to be made within 45 days to qualify for deductions in the same year. This change improves MSME cash flows and enforces timely vendor payments.
Under Section 43B(h), any business purchasing goods or services from registered MSMEs is subject to the 45-day payment rule. This includes all taxpayers, regardless of MSME registration, ensuring timely settlements to micro and small enterprises.
Deferred tax liabilities are not considered for deduction under Section 43B, as only actual payments qualify. Hence, deferred tax is not deductible unless paid, as per 43B disallowance of Income Tax Act rules.
Disallowed expenses in income tax include those not paid within the due dates under relevant provisions like Section 43B. These may cover unpaid statutory dues, interest, and employee benefits if not cleared in the same financial year.
To claim a deduction under Section 43B of the Income Tax Act, the payment must be made either within the financial year or by the due date for filing the income tax return.
Under the MSME 43B(h) provision, payments to micro and small enterprises must be made within 45 days to be eligible for tax deductions in the same year. Delays result in disallowance until payment is made.
No, TDS (Tax Deducted at Source) is not covered under Section 43B. This section deals with actual payments like GST, PF, interest, and dues to MSMEs, not tax deductions made on behalf of others.
Yes, if an advance payment is made toward an eligible Section 43B expense, it can be claimed as a deduction. The key condition is that the payment must be made before the income tax return filing due date.
Yes, employer contributions to the National Pension Scheme (NPS) are deductible under Section 43B of the Income Tax Act 1961, provided the payment is made before the due date of filing the income tax return.
The provision of Section 43B allows deductions for certain expenses paid before the due date of filing the return, even if they were not paid during the financial year. This offers flexibility while maintaining compliance.
Section 43B impacts deferred payments by disallowing expense deductions unless the payment is actually made. For MSMEs under Section 43B(h), delayed vendor payments beyond 45 days will only be deductible in the year of actual settlement.
