Rule 86B of GST: What Every Business With ₹50 Lakh+ Monthly Turnover Must Know

If your business crosses ₹50 lakh in monthly taxable turnover, Rule 86B of the CGST Rules directly affects how you can use your Input Tax Credit (ITC). Introduced on 1st January 2021, this rule prevents businesses from settling 100% of their GST liability through ITC alone – requiring at least 1% to be paid in cash every month. In this article, you will learn exactly who this rule applies to, how to calculate your cash payment obligation, what exemptions are available, and what happens if you do not comply.

Key Facts About Rule 86B at a Glance

What Is Rule 86B and Why Was It Introduced?

Before Rule 86B came into effect, businesses could discharge their entire GST output tax liability using ITC – with no minimum cash payment required. While this was efficient for working capital, it opened the door for fraudsters who created fake invoices to generate bogus ITC and avoid paying actual tax in cash.

The government introduced Rule 86B under Notification No. 94/2020 – Central Tax specifically to curb fake invoicing and tax evasion. By making a minimum 1% cash payment mandatory, the rule ensures that large taxpayers have genuine business activity and are not solely relying on fraudulent ITC to settle their tax dues.

In simple terms: if you have a large turnover and plenty of ITC, you still have to pay at least a small portion of your GST in real cash every month.

Who Does Rule 86B Apply To?

Rule 86B applies to any registered person whose value of taxable supply in a month exceeds ₹50 lakh. This is assessed on a month-by-month basis – not on annual turnover.

What Counts as “Taxable Supply” for This Purpose?

Only domestic taxable supplies are considered. The following are excluded from the ₹50 lakh threshold calculation:

• Exempt supplies (nil-rated goods/services)
• Zero-rated supplies (exports and SEZ supplies under LUT)
• Non-GST supplies

So if your total supplies in a month are ₹70 lakh but ₹25 lakh are exempt, only ₹45 lakh is counted – and Rule 86B does not apply that month.

Practical Example

A manufacturer has ₹1 crore in taxable sales in a month at 18% GST, creating an output tax liability of ₹18 lakh. Under Rule 86B, a maximum of ₹17,82,000 (99%) can be paid using ITC. The remaining ₹18,000 (1%) must be deposited via the Electronic Cash Ledger. This check must be performed before filing GSTR-3B every month.

Exemptions From Rule 86B – Who Gets Relief?

Rule 86B does not apply in all cases. The following categories of registered persons are specifically excluded:

1. Income Tax Payment Criterion

If the registered person – or their proprietor, karta, managing director, whole-time director, or partners – has paid more than ₹1 lakh in income tax under the Income Tax Act, 1961, in each of the last two financial years (for which the due date to file returns under Section 139(1) has passed), Rule 86B does not apply.

2. GST Refund Criterion

If the registered person received a GST refund exceeding ₹1 lakh in the previous financial year on account of:

• Unutilised ITC from exports under Letter of Undertaking (LUT), or
• Inverted duty structure (where the input tax rate is higher than the output tax rate)

then the 1% cash payment condition is waived.

3. Prior Cash Payment in Current Financial Year

If the taxpayer has already cumulatively paid more than 1% of total output tax liability in cash through the Electronic Cash Ledger during the current financial year up to that month, Rule 86B does not apply for the said month.

4. Government and Public Sector Entities

Government departments, public sector undertakings (PSUs), local authorities, and statutory bodies are entirely exempt from Rule 86B.

5. Commissioner’s Discretion

The Commissioner may, upon application and with recorded reasons, remove the Rule 86B restriction for a specific taxpayer after due verification.

Consequences of Non-Compliance With Rule 86B

Ignoring Rule 86B is not just a paperwork issue – it carries serious financial and legal consequences.

Importantly, Rule 21 of the CGST Rules was amended to explicitly include violation of Rule 86B as a ground for GST registration cancellation. A cancelled GST registration means a business cannot issue tax invoices, collect GST, or claim ITC – effectively shutting down GST operations.

Legal Challenge to Rule 86B – What Businesses Should Know

In a notable development, the Himachal Pradesh High Court ruled in the case of A.M. Enterprises v. State of Himachal Pradesh that Rule 86B lacks sufficient statutory backing under the CGST Act and is ultra vires (beyond the legal authority of) the Act. The court held that restricting access to ITC – which represents the taxpayer’s own funds already paid to the government – without clear legislative authority is unjustified.

However, this ruling applies to the jurisdiction of Himachal Pradesh and is subject to further appeals. Rule 86B remains in force nationally. Businesses should continue to comply unless specifically advised otherwise by their tax counsel, especially given the risk of notices and registration cancellation.

Practical Compliance Checklist for Rule 86B

1. Before filing GSTR-3B each month, calculate your total taxable supply for that month (excluding exempt and zero-rated turnover).
2. If taxable supply exceeds ₹50 lakh, verify whether you qualify for any of the four exemptions listed above.
3. If no exemption applies, ensure at least 1% of your output tax liability is available and deposited via the Electronic Cash Ledger before filing.
4. Maintain documentation of income tax payments for the last 2 financial years to support exemption claims.
5. If you received GST refunds exceeding ₹1 lakh in the previous year (exports/inverted duty), record this as an exemption basis in your compliance file.
6. Track cumulative cash payments made in the current financial year – once you cross 1% of cumulative output tax, you are exempt for the rest of that year.

Conclusion

Rule 86B is one of the most significant compliance requirements introduced under GST for larger businesses and one of the most overlooked. If your monthly taxable turnover crosses ₹50 lakh, you are required to pay at least 1% of your GST liability in cash every month, regardless of available ITC. Failing to do so can trigger GST notices, demand proceedings, or even registration cancellation. The rule does provide meaningful exemptions – particularly for businesses with a clean income tax payment history or those who have received substantial GST refunds but these must be tracked and documented proactively. The safest approach is a monthly pre-filing compliance check against Rule 86B before submitting your GSTR-3B return.

Frequently Asked Questions (FAQs)

Does Rule 86B apply if my turnover exceeds ₹50 lakh annually but not monthly?

No. Rule 86B is evaluated on a monthly basis. If your taxable supply in any individual month does not cross ₹50 lakh, the rule does not apply for that particular month, regardless of your annual turnover.

Can RCM payments be counted toward the 1% cash payment under Rule 86B?

No. Payments made under the Reverse Charge Mechanism (RCM) are not considered part of the output tax liability for the purpose of calculating the 1% minimum cash payment requirement under Rule 86B.

What if I have enough ITC to cover 100% of my liability – do I still need to pay 1% in cash?

Yes, unless you qualify for one of the listed exemptions. Having surplus ITC does not override the Rule 86B requirement. You must still pay at least 1% in cash via the Electronic Cash Ledger if the rule applies.

Does Rule 86B apply to both CGST and SGST separately?

The rule applies to the combined output tax liability. The 1% cash payment is calculated on total output tax liability (CGST + SGST/UTGST + IGST) for the month.
