📌 1% Cash Payment Rule in GST (Rule 86B)
The 1% cash rule under GST comes from Rule 86B GST, introduced by the government to curb fake invoicing and ITC misuse.
🔍 What does the rule say?
👉 If your monthly taxable turnover exceeds ₹50 lakh, then:
➡️ You cannot use ITC fully to pay GST liability
➡️ You must pay at least 1% of output tax liability in cash
🧾 Simple Example
Output GST liability = ₹10,00,000
ITC available = ₹10,00,000
👉 Normally: Pay full via ITC
👉 Under Rule 86B:
Minimum ₹10,000 (1%) must be paid in cash
Remaining ₹9,90,000 via ITC
🚫 When Rule 86B does NOT apply (Exceptions)
You are exempt from 1% rule if ANY of these apply:
✔️ Income tax paid > ₹1 lakh in last 2 years (by proprietor/partner/director)
✔️ Received refund > ₹1 lakh in preceding FY (ITC or export refund)
✔️ Output tax already paid in cash ≥ 1% cumulatively
✔️ Government department / PSU / local authority
✔️ Registered person is exempted by Commissioner
⚠️ Important Points
Applies per GSTIN, not PAN level
Checked monthly (turnover > ₹50 lakh in a month)
Only for taxable supplies (not exempt/export without tax)
🎯 Practical Insight (Very Important)
👉 This rule mainly targets:
Fake billing businesses
High ITC claim without real transactions
👉 Genuine businesses usually fall under exemptions.
