Goods and Services Tax (GST) was designed to simplify India’s indirect taxation system, but for many small businesses, it has created unexpected working capital challenges. In particular, issues around Input Tax Credit (ITC), rate mismatches, and delayed refunds have tied up much-needed funds.
This blog post explores how GST impacts working capital, especially for MSMEs, and what businesses can do to mitigate these effects.
💡 Understanding Working Capital
Working capital = Current Assets – Current Liabilities
For small businesses, it includes:
- Cash
- Inventory
- Receivables
- Payables
Any delay in converting input (purchases) into output (sales and collections) directly affects liquidity.
🔍 How GST Impacts Working Capital
1. Blocking of Input Tax Credit (ITC)
Input Tax Credit allows businesses to claim a credit on taxes paid on purchases. However, there are several issues that result in blocked or unusable ITC:
Common Reasons for ITC Blocking:
- Purchase from unregistered vendors
- Supplier did not file GSTR-1 or paid GST
- Goods/services not used for business
- Ineligible categories like motor vehicles, employee expenses, etc.
- Goods in transit or capital goods not yet capitalized
➡️ This ties up cash in the GST ledger, creating a shortfall in working capital.
2. Rate Mismatches in Input vs Output
A business may pay higher GST on purchases but charge lower GST on sales, creating an accumulation of ITC:
Example:
- Raw material taxed at 18%, but finished goods sold at 5%
- Input tax = ₹18,000; Output tax = ₹5,000
- Balance ₹13,000 is blocked unless eligible for refund
This accumulated credit cannot always be claimed as a refund, especially for traders, leading to locked-up capital.
3. Delayed Refunds in Exports or Inverted Duty Structure
- Exporters are eligible for GST refunds on zero-rated supplies
- Businesses under Inverted Duty Structure (inputs taxed higher than outputs) can also claim refunds
But the refund process is slow and paperwork-intensive:
- Manual interventions
- Scrutiny by officers
- Delays in processing
➡️ This blocks significant liquidity for weeks or months.
4. Monthly GST Payments (GSTR-3B)
Even before collecting payments from clients, businesses must pay GST by the 20th of the following month.
- Creates a cash flow mismatch
- Many MSMEs operate on credit sales with 30–90 day terms
➡️ Paying tax in advance of collections hurts working capital.
🚫 Consequences of GST-Induced Working Capital Crunch
- Delay in supplier payments
- Missed growth opportunities due to fund shortage
- Dependency on expensive credit (overdrafts or NBFC loans)
- Increased financial stress and compliance costs
✅ How to Resolve Working Capital Challenges Under GST
1. Vendor Management & Compliance
- Purchase only from GST-compliant vendors
- Check vendor filings through GSTR-2B reconciliation
- Block list defaulting vendors from future orders
2. Regular ITC Reconciliation
- Monthly matching of ITC in books vs GSTR-2B
- Identify mismatches early to take corrective action
3. File Refunds Timely
- For export and inverted duty structure refunds
- Maintain complete documentation
- Use automated filing tools to reduce errors
4. Consider Working Capital Loan Options
- Apply for GST-based loan products (e.g. GST Invoice Financing)
- Opt for NBFCs offering quick disbursements
5. Cash Flow Planning
- Create a monthly GST outflow calendar
- Forecast tax liabilities and buffer working capital accordingly
- Align collections with GST payment due dates
6. Utilize GST Exemptions & Composition Scheme (if eligible)
- Small businesses under ₹1.5 crore turnover can opt for Composition Scheme to pay tax at a fixed rate without ITC hassles
💼 Expert Tip
