Rule 86B (ITC Utilisation Restriction)

Rule 86B (ITC Utilisation Restriction) is an anti-evasion provision under the Central Goods and Services Tax (CGST) Rules, 2017. It mandates that registered businesses with monthly taxable supplies exceeding 50 lakh rupees cannot utilize their electronic credit ledger balance to discharge more than 99% of their output tax liability, requiring at least 1% payment in cash.

The Central Board of Indirect Taxes and Customs (CBIC) introduced Rule 86B through Notification No. 94/2020-Central Tax to tackle circular trading networks and fake invoicing cartels that used fraudulent input tax credit (ITC) to eliminate cash tax payments entirely. Grounded in Section 49(12) of the CGST Act, the provision enforces a floor for liquidity without dismantling a taxpayer's entitlement to legitimate tax credits.

How Does Rule 86B (ITC Utilisation Restriction) Work?

The core mechanic of Rule 86B restricts the portion of output tax liability that you can clear using accumulated credits in your electronic credit ledger, maintained in Form GST PMT-02. Crucially, the rule does not block, forfeit, or cancel unutilised credit. Any credit remaining after satisfying the 99% limit stays in your ledger for use in subsequent tax periods.

The 50 Lakh Rupee Monthly Threshold

The restriction activates only in tax periods where your total value of taxable supplies exceeds 50 lakh rupees. Under the rule, you must exclude two categories of turnover from this calculation: exempt supplies and zero-rated supplies. Zero-rated supplies comprise both physical exports of goods or services and supplies made to Special Economic Zone (SEZ) developers or units. Because the calculation is monthly, a taxpayer might be subject to Rule 86B in October when seasonal turnover spikes, but remain free from it in November when turnover drops below the 50 lakh rupee mark.

Exclusion of Reverse Charge Liabilities

The 1% cash payment mandate applies solely to forward-charge output tax. Section 2(82) of the CGST Act expressly excludes tax payable under the reverse charge mechanism (RCM) from the definition of output tax. Because RCM liabilities under Section 9(3) and Section 9(4) must already be paid entirely through the electronic cash ledger pursuant to Section 49(4), RCM payments cannot be counted toward the 1% cash settlement demanded by Rule 86B.

Entity-Level vs GSTIN-Level Application

Taxpayers with operations across multiple states must track Rule 86B separately for every registered Goods and Services Tax Identification Number (GSTIN). The 50 lakh rupee threshold and output tax caps are evaluated on each state return independently, not aggregated across the corporate Permanent Account Number (PAN).

What Are the Key Exceptions to Rule 86B?

To ensure established commercial enterprises and capital-intensive manufacturers do not suffer arbitrary cash-flow burdens, the first proviso to Rule 86B establishes five statutory carve-outs. Meeting any one of these conditions lifts the restriction, allowing you to settle up to 100% of your output tax through eligible ITC:

• Income Tax Filing History (Clause a): The restriction does not apply if the registered person, proprietor, Karta, managing director, or any two whole-time directors, partners, or members of the board of trustees have paid more than 1 lakh rupees in income tax under the Income-tax Act, 1961. This payment threshold must be met in each of the two preceding financial years for which the return filing deadline under Section 139(1) has expired.
• Export Refund on Unutilised ITC (Clause b): The restriction is lifted if the taxpayer received a refund exceeding 1 lakh rupees in the preceding financial year under Section 54(3) on account of zero-rated supplies made without payment of tax.
• Inverted Duty Structure Refund (Clause c): Taxpayers who received a refund of unutilised ITC exceeding 1 lakh rupees in the preceding financial year under Section 54(3) due to an inverted duty structure are exempt.
• Cumulative Cash Payment Ratio (Clause d): If the cumulative output tax liability discharged through the electronic cash ledger from the beginning of the financial year up to the current tax period exceeds 1% of the cumulative output tax liability over that same timeframe, the restriction does not apply for that month.
• Specified Entities (Clause e): Government departments, Public Sector Undertakings (PSUs), local authorities, and statutory bodies established under central or state statutes are fully exempt.

In addition, the second proviso empowers the jurisdictional Commissioner or an authorized officer to lift the restriction after conducting suitable verifications and establishing proper safeguards.

Step-by-Step Calculation: Rule 86B in Practice

Understanding how the 1% cash obligation interacts with ledger balances requires looking at both standard monthly filings and cumulative adjustments across quarters.

Scenario A: Standard Monthly Liability Discharge

Suppose a manufacturing company registered on the GST portal reports domestic taxable turnover of 80 lakh rupees in August. The company does not meet the income tax or refund exemption criteria. Its output tax liability at 18% GST is 14,40,000 rupees, and it holds 20,00,000 rupees of eligible credit in its electronic credit ledger.

Even though the enterprise possessed more than enough credit to clear the full liability, Rule 86B mandated a cash deposit of 14,400 rupees before filing Form GSTR-3B.

Scenario B: Applying the Cumulative Cash Exemption

Now consider how Clause (d) of the first proviso functions later in the financial year. Assume the same company paid 1,00,000 rupees in cash against output tax in April and May due to temporary ITC shortages. By October, its cumulative output tax liability for the financial year reaches 60,00,000 rupees. The 1% threshold on 60,00,000 rupees is 60,000 rupees. Because the company already deposited 1,00,000 rupees in cash cumulatively, its cash discharge ratio stands at 1.67%. In October, even if monthly taxable turnover exceeds 50 lakh rupees, the company qualifies for the cumulative exemption and can discharge 100% of October's output tax using available ITC.

Rectifying Non-Compliance and Handling Audit Scrutiny

The GST portal does not always trigger a hard validation block when a taxpayer offsets 100% of their liability with ITC despite breaching the 50 lakh rupee turnover mark. As a result, accounting teams often overlook the 1% requirement during manual return preparation. Such oversights trigger scrutiny notices under Form GST ASMT-10 or demand notices under Section 73 or Section 74 of the CGST Act.

The Institute of Chartered Accountants of India (ICAI) and tax authorities have outlined the standard procedure for regularizing this error. If you utilised ITC in excess of 99%, the underlying credit itself remains legitimate. However, you face a procedural shortfall in cash discharge. To regularize the period, you must deposit the unpaid 1% cash balance along with interest under Section 50(1) calculated from the return due date to the actual date of cash deposit. You can remit this payment using Form GST DRC-03, while simultaneously reversing or adjusting the excess credit utilized in your ledger.

To defend against GST audit objections, companies claiming exemption under the income tax proviso must maintain an audit trail. Retain copies of Form ITR-V acknowledgements, tax computation sheets, and challans showing tax payments above 1 lakh rupees for the company or two qualifying directors on the Income Tax department portal.

Frequently Asked Questions

Does Rule 86B apply separately to each GSTIN in a multi-state company?

Yes. Rule 86B applies independently to each GSTIN. If your company operates across five states, you must evaluate the 50 lakh rupee monthly taxable turnover threshold and exception eligibility for each state registration separately.

Can reverse charge tax payments fulfill the 1% cash requirement?

No. Under Section 2(82) of the CGST Act, reverse charge liabilities do not constitute output tax. RCM taxes must be paid in cash under Section 49(4) and cannot be counted toward the 1% cash settlement demanded under Rule 86B.

Does Rule 86B cause unutilised input tax credit to expire?

No. Rule 86B only restricts the proportion of output tax you can clear using ITC in a given month. Any unutilised credit remains in your electronic credit ledger and carries forward indefinitely for future tax periods.

How does the cumulative cash exception work under Rule 86B?

Under Clause (d) of the first proviso, you calculate total output tax paid in cash from 1 April of the current financial year through the current month, divided by total cumulative output tax liability for the same period. If this ratio exceeds 1%, the restriction does not apply for that month.
