Working capital is the difference between current assets and current liabilities, showing a company’s ability to meet short-term obligations. It is rightly called the lifeblood of business as it ensures smooth daily operations. Many firms wrongly see working capital management as only invoice collections, but it actually requires a holistic approach covering receivables, payables, inventory, taxation, and compliance.

For instance, under the MSMED Act, payments to MSMEs must be made within 45 days, failing which interest applies. The Income Tax Act (Section 43B(h)) disallows late MSME payments as deductible expenses. Similarly, GST law requires input tax credit reversal if invoices are unpaid beyond 180 days, while the Companies Act mandates MSME-1 filings and ageing disclosures. Thus, optimizing working capital means not only freeing cash but also staying legally compliant and financially efficient.

In this article, CA Manish Mishra talks about Optimizing Working Capital: Strategies Beyond Just Invoice Collections.

Legal Frameworks Governing Working Capital

MSMED Act, 2006

The Micro, Small and Medium Enterprises Development Act, 2006 is designed to protect micro and small vendors from delayed payments. Under Section 15, buyers must pay suppliers within 45 days of accepting goods or services. If they don’t, they are legally bound to pay interest at three times the RBI bank rate. This interest cannot be claimed as a tax-deductible expense, so companies not only pay more but also face a higher tax burden. This law forces businesses to give priority to MSME payments, ensuring fairness and financial discipline.

Section 43B(h) of the Income Tax Act (2024 amendment)

Introduced by the Finance Act 2023, Section 43B(h) came into effect on 1 April 2024. It links MSME payments directly with income tax compliance. If dues to micro or small enterprises are not cleared within MSMED timelines, businesses cannot claim them as deductible expenses in that financial year. The deduction is allowed only after actual payment. This measure ensures companies restructure their payment cycles because unpaid MSME dues directly increase their taxable income and tax liability.

Companies Act & MCA Reporting

The Companies Act, 2013 also addresses MSME dues through stricter reporting and transparency rules:

• Companies must file MSME-1 returns twice a year if they owe MSMEs for more than 45 days.

• Schedule III of the Act requires financial statements to disclose detailed ageing of trade payables and any related MSME interest obligations.

• Sections 185 and 186 regulate inter-corporate loans, guarantees, and investments, ensuring that group companies cannot misuse liquidity under the garb of working capital adjustments.

• Section 188 makes sure that extended credit terms to related parties are conducted at arm’s length, preventing unfair or hidden transactions.

Insolvency and Bankruptcy Code (IBC)

The Insolvency and Bankruptcy Code (IBC), 2016 provides a powerful recovery tool to suppliers. If a company defaults on payments of ₹1 crore or more, operational creditors, including MSMEs, can file for insolvency proceedings against the defaulting company in the NCLT. However, before filing, the creditor must issue a demand notice, giving the buyer a final opportunity to pay or raise a dispute. This provision makes payment delays risky, since even small vendors can escalate matters legally, leading to insolvency proceedings and reputational damage for the buyer.

GST-Linked Working Capital Triggers

Under the Goods and Services Tax (GST) regime, compliance rules directly affect a company’s working capital cycle. Delays in payments, vendor non-compliance, or restrictions on ITC (Input Tax Credit) can lock up significant funds, making GST a crucial factor in liquidity management.

ITC and Payment Terms

• Rule 37: If a business claims ITC on a supplier invoice but does not pay the supplier within 180 days, the ITC must be reversed with interest. ITC can be reclaimed once the payment is made.

• Rule 37A: Even if the buyer has paid, ITC will be disallowed if the supplier fails to deposit GST or file returns. The buyer must reverse ITC until the supplier complies.

Rule 86B – 1% Cash Rule

Rule 86B mandates that businesses with monthly taxable supplies above ₹50 lakh must pay at least 1% of their GST liability in cash, regardless of ITC balance. While exceptions exist (like exporters or firms with sufficient income tax history), this rule compels companies to maintain cash reserves, directly affecting working capital planning.

E-Invoicing & Vendor Compliance

E-invoicing is mandatory for businesses with turnover ₹5 crore or more. Suppliers must generate invoices through the IRP with a valid IRN and QR code. If not, buyers cannot claim Input Tax Credit (ITC), causing mismatches and cash blockage. Timely invoice acceptance ensures smooth credit flow and liquidity. 

Receivables Management Beyond Collections

Trade Receivables Discounting System (TReDS)

The TReDS platform, regulated by the RBI, allows MSME suppliers to discount invoices approved by large buyers with banks or NBFCs. A notification in November 2024 made TReDS onboarding mandatory for companies with turnover above ₹250 crore and for CPSEs. This ensures that MSMEs receive quicker liquidity, while buyers gain credibility for supporting timely payments and improving supply chain trust.

Factoring Regulation (Amendment) Act, 2021

Earlier, only banks could act as factors, but the 2021 amendment widened access by allowing more NBFCs to provide factoring services. This change significantly expanded the receivable financing ecosystem in India, enabling businesses to sell their unpaid invoices to multiple financial institutions for immediate working capital. It reduces dependence on traditional collections and helps companies manage liquidity effectively.

Export Receivables

For exporters, receivable management is critical due to payment risks from overseas buyers. The Export Credit Guarantee Corporation (ECGC) provides insurance cover against defaults, political risks, and delays in foreign payments. Additionally, under the RBI’s trade credit framework, importers can avail supplier’s or buyer’s credit up to 1 year for non-capital goods and up to 3 years for capital goods, offering flexibility in financing international transactions.

Payables Strategy and Legal Safeguards

MSME Vendors

When dealing with micro and small enterprises, businesses must comply with the MSMED Act, 2006, which requires payments within 45 days. To avoid defaults and penalties, companies should maintain an updated database of vendors’ Udyam registration status. This helps identify which suppliers qualify as MSMEs. Automating invoice alerts ensures finance teams are reminded before the 45-day deadline, reducing the risk of interest liability and tax disallowances under Section 43B(h) of the Income Tax Act.

Contractual Clauses

Contracts play a vital role in protecting working capital. Clear acceptance timelines should be built into agreements through systems like Goods Receipt Notes (GRN) or Service Entry Sheets (SES), which confirm when the 45-day clock for MSME payments begins. Agreements should also include enforceable set-off and retention money clauses to allow adjustments against damages or defects, without breaching statutory obligations. Additionally, businesses must safeguard against unilateral debit notes issued by customers, as these can arbitrarily reduce receivables and disrupt cash flow. Strong drafting of terms ensures fair treatment for both parties.

Inventory Financing

Working capital is often tied up in unsold inventory. To unlock this, businesses can use Negotiable Warehouse Receipts (NWRs) issued under the Warehouse Development and Regulation Authority (WDRA) framework. These receipts certify ownership of stored goods and can be pledged with banks for financing. This mechanism allows companies to raise funds without liquidating stock, converting idle inventory into working capital while ensuring legal recognition and security for lenders.

Tax Provisions Impacting Working Capital

TDS/TCS on Trade Transactions

Two important provisions of the Income Tax Act directly influence working capital:

• Section 194Q: Buyers whose turnover exceeds ₹10 crore in the previous financial year must deduct 0.1% TDS on purchases of goods from a seller if the value crosses ₹50 lakh in a year. This reduces immediate cash outflow for sellers, as part of the invoice value is withheld until tax credit is adjusted.

• Section 206C(1H): Sellers with turnover above ₹10 crore must collect 0.1% TCS on receipts from a buyer exceeding ₹50 lakh in a year. This increases upfront cash burden for buyers.

Since both provisions can apply simultaneously, businesses must ensure PAN validation and proper ERP configuration to avoid double levy of TDS and TCS. These small percentages, though seemingly minor, impact cash flows and reconciliation cycles, thus affecting working capital planning.

Advances & Deposits under Companies Act

The Companies (Acceptance of Deposits) Rules, 2014, framed under the Companies Act, 2013, classify customer advances as potential “deposits” if not adjusted in time. Specifically, advances received for goods or services must be appropriated within 365 days; otherwise, they may be treated as deposits, attracting stringent compliance requirements, restrictions, and penalties.

For businesses, this means advances cannot be used indefinitely as a source of working capital. Companies must align their sales, delivery, and accounting systems to ensure advances are cleared within the statutory period. This provision prevents misuse of customer funds but also restricts how much flexibility businesses have in managing liquidity.

Challenges in Implementation

Even with strong frameworks for working capital optimization, businesses face practical challenges in execution.

• Data Overload and Vendor Master Mismatches: Large organizations deal with thousands of invoices and vendors. Errors in vendor master data such as incorrect GSTIN, Udyam registration details, or PAN can cause compliance failures. Managing this data load while keeping it updated is a significant hurdle.

• Risk of ITC Reversal Due to Vendor Non-Compliance: Under GST, buyers can lose input tax credit (ITC) if suppliers fail to file returns or deposit tax (Rule 37A). Even if the buyer has paid, ITC must be reversed until the vendor complies, creating uncertainty and blocking working capital.

• Time Pressure for GST Filings and Reconciliations: GST requires timely filing of monthly/quarterly returns and reconciliations between purchase invoices and GSTR-2B. Any delay or mismatch risks penalties, late fees, and ITC reversals. Finance teams face constant time pressure to meet statutory deadlines.

• Balancing Liquidity Needs with Legal Restrictions: Companies often delay payments to preserve cash, but laws like the MSMED Act (45-day rule) and Section 43B(h) of the Income Tax Act prohibit excessive delays. This creates tension between treasury goals and legal compliance, requiring careful planning.

Conclusion

Optimizing working capital today requires far more than chasing collections; it demands a compliance-driven strategy that blends finance with legal obligations. Businesses must align supplier payments with the MSMED Act’s 45-day rule, as delays attract interest penalties and disallowances under Section 43B(h) of the Income Tax Act. On the indirect tax side, GST provisions like Rule 37 and Rule 37A force companies to settle invoices on time and monitor vendor compliance, since unpaid dues or non-filing by suppliers can lead to input tax credit (ITC) reversals, blocking essential liquidity.

Beyond tax compliance, effective receivables management through TReDS, factoring, and export credit mechanisms ensures steady cash inflows, while strategies like Negotiable Warehouse Receipts (NWRs) unlock value from inventory. The Companies Act further reinforces discipline through deposit rules, MSME disclosures, and reporting requirements. Rather than a burden, these frameworks create a structured financial ecosystem that reduces risks, builds supplier confidence, and enhances trust with lenders and regulators.
