MUMBAI — It was hailed as a revolutionary shield for India’s micro and small enterprises. When the government strictly enforced Section 43B(h) of the Income Tax Act—mandating that larger companies must pay their registered Micro and Small Enterprise (MSE) suppliers within 45 days—small business owners celebrated. The perennial nightmare of waiting 90, 120, or even 180 days for invoices to clear was supposed to end.
Now that the tax cycles have passed and the ground reality has set in, the verdict from India’s SME corridors is mixed. While the law has successfully injected liquidity into many supply chains, it has also triggered unintended consequences, forcing owners to walk a tightrope between protecting their cash flow and preserving vital client relationships.
The Tax Teeth Behind the Law
Unlike previous iterations of MSME protection laws that lacked real consequences, Section 43B(h) has immense structural power. If a large corporate buyer fails to pay a registered micro or small vendor within 15 days (or up to 45 days if a written agreement exists), the buyer cannot claim that expense as a tax deduction for that financial year.
The unpaid amount is added directly back to the buyer’s taxable income, forcing them to pay a massive tax penalty on money they still owe. This sudden fiscal pressure caused panic in corporate procurement departments, triggering a wave of delayed clearances.
The Unintended Backlash: Squeezing Out Small Vendors
While many large corporates complied and cleared backlogs, a more worrisome trend has emerged in industrial hubs like Pune, Ahmedabad, and Chennai. To avoid the rigid 45-day tracking hassle, some large corporations have quietly begun shifting their procurement contracts away from registered Micro and Small enterprises.
Instead, they are redirecting orders toward Medium enterprises or non-registered businesses that fall outside the ambit of Section 43B(h), leaving law-abiding small business owners in a bizarre dilemma.
According to Economic Times, Rs 8.1 lakh crore is locked in delayed payments to MSMEs, impacting working capital and restricting growth. This persistent challenge underscores why the 45-day rule remains critical even as corporates seek loopholes.
“We fought for years to get paid on time, but now some of our oldest clients are asking us to either cancel our Udyam registration or lose the contract,” says an auto-component manufacturer based in Maharashtra. “They tell us frankly that their accounts department cannot handle the compliance burden of the 45-day window.”
Survival Strategies for SME Owners
To navigate this shifting landscape, successful small businesses are shifting from a purely defensive stance to strategic positioning:
• Leveraging TReDS (Trade Receivables Discounting System): Smart SMEs are onboarding onto digital platforms like TReDS. This allows them to upload invoices and get paid within 24 to 48 hours by financial institutions, while the large corporate buyer gets their extended credit period, keeping both parties happy.
Industry experts expect continued momentum through TReDS expansion in 2026, further improving access to working capital for small businesses.
• The “Premium Supplier” Pivot: Rather than relying solely on the law to enforce behavior, small firms are focusing on high-spec, proprietary, or highly customized products that corporations cannot easily source from a non-registered alternative.
• Open Financial Dialogue: SME founders are initiating transparent conversations with corporate purchasing heads before shipping orders, aligning payment milestones directly with the buyer’s internal compliance calendars to minimize friction.
The Long-Term Outlook
Section 43B(h) has successfully shifted delayed payments from an administrative afterthought to a boardroom-level compliance issue for India’s biggest companies. However, for small businesses, the true test of survival is no longer just manufacturing a great product—it is masterfully managing the compliance politics of the cash flow timeline.
As SMEs strengthen their financial resilience and optimize cash flow management, leveraging a global b2b portal can help them connect with verified buyers, diversify customer bases, and reduce dependence on a limited number of large corporate clients.
