Quick Answer: What Is the Rule 86B 1% Cash Liability Restriction?

Rule 86B limits Input Tax Credit usage to a maximum of 99% of monthly output tax liability if monthly taxable sales exceed ₹50 Lakhs. The remaining 1% liability must be paid in cash via Electronic Cash Ledger, unless exempt (e.g. Income Tax > ₹1L paid, export refunds received).

  • Applies on monthly taxable turnover > ₹50 Lakhs (excluding exempt & exports).
  • Mandates minimum 1% output tax payment through Electronic Cash Ledger.
  • Exempt if proprietor/partners paid > ₹1L Income Tax in previous 2 fiscal years.
