Presumptive Tax Shakeup: New Income Tax Act 2025 Barring Losses Could Skyrocket Tax Burden for Small Businesses

Presumptive Tax Shakeup: New Income Tax Act 2025 Barring Losses Could Skyrocket Tax Burden for Small Businesses​

The newly introduced provisions within the Income Tax Act, 2025 are set to fundamentally alter how small businesses and professionals calculate their tax liability. While the basic structure of presumptive taxation remains, a critical change bars taxpayers from utilizing various losses, allowances, and deductions against income calculated under this scheme.

This consolidation, intended to streamline compliance, has significant implications for those who rely on presumptive income to mitigate risk and reduce taxable earnings. Experts warn that this tight restriction could translate directly into a higher tax burden across the SME sector.

Section 58 Replaces Multiple Presumptive Taxation Provisions​

Prior to the new law, presumptive taxation was managed through three distinct sections: Section 44AD for eligible businesses, Section 44ADA for specified professionals, and Section 44AE for transport operators. These provisions offered prescribed fixed income rates, such as 6 percent or 8 percent of turnover for some businesses, and 50 percent for designated professions.

The Income Tax Act, 2025 now consolidates all these functions under a singular Section 58. Furthermore, the terminology has been updated from 'previous year' and 'assessment year' to the modern concept of a 'Tax Year'. Crucially, the core presumptive income rates and turnover thresholds have not been drastically altered.

The Game Changer: No Loss Set-offs Against Presumptive Income​

The most impactful modification introduced by Section 58(4) is the absolute prohibition on claiming any loss, allowance, or deduction against income computed under the presumptive taxation scheme. This represents a major shift from the previous framework of the Income Tax Act, 1961.

Under the older law, taxpayers could utilize specific deductions and set-offs to reduce their taxable income even when opting for presumptive tax. Section 58(4) eliminates this option entirely.

How the New Act Could Increase Tax Liability​

This legislative change is poised to lead to higher tax liabilities because the mechanism by which presumptive income could be reduced through financial mitigation strategies has been removed. This means that taxpayers' taxable income will stand at the calculated presumptive amount, regardless of their overall economic positioning or pre-existing losses.

Tax experts illustrate this risk with a practical scenario. A resident freelancer generating ₹3 crore in gross digital receipts, who also holds a short-term capital loss of ₹6 lakh, highlights the impact. Under previous law, the presumptive income (calculated at 6 percent, amounting to ₹18 lakh) could have been reduced by the capital loss and eligible Chapter VI-A deductions, potentially lowering the tax bill significantly.

Under the Income Tax Act, 2025, however, that reduction is disallowed. The taxable income remains at ₹18 lakh, resulting in a higher tax liability for the taxpayer despite their ability to financially offset losses elsewhere.

Deductions and Loss Carry-Forward Are Now Inoperable​

Previously, taxpayers opting for presumptive taxation could access various benefits beyond standard business expense deductions. These included inter-head set-offs of house property losses, carry-forward and set-off of brought-forward business losses, and applicable Chapter VI-A deductions such as those related to medical insurance premium under Section 80D.

Section 58(4) explicitly states that any loss, allowance, or deduction permissible under the Act cannot be claimed against income computed via presumptive taxation provisions. Consequently, these existing tax planning tools can no longer be used to bring down the taxable income when using presumptive schemes.

Audit Compliance and Stricter Scrutiny Under Section 58​

The turnover-based audit thresholds remain broadly consistent with the previous framework. Businesses crossing prescribed limits are still subject to a tax audit; the higher ₹10 crore threshold remains available where cash receipts and payments do not exceed 5 percent of total transactions.

However, the interaction between presumptive taxation and audit has become considerably more stringent. Under the Income Tax Act, 2025, taxpayers who declare profits below the prescribed rates are subject to heightened compliance requirements. They face increased pressure to maintain proper books of account and undergo audits where applicable. In essence, while the quantitative thresholds remain similar, the regulatory scrutiny under the new regime is significantly tighter.
