Electronic Credit Ledger in GST: Rule 86B, Blocks & Refunds

The electronic credit ledger in GST is the digital account on the GST portal that holds your accumulated input tax credit and governs how you can spend it against output tax. It opens automatically the day you register under GST, updates every time a return is filed, and is the single record the portal treats as the source of truth when it processes your monthly liability.

What Sits Inside the Ledger

Under Section 49 of the Central Goods and Services Tax Act, self-assessed input tax credit flows into the electronic credit ledger when you file your returns.1CBIC-Tax Information. CGST Act Section 49 The balance is not one pool. It is split into three sub-accounts, one for each type of GST:

  • Integrated Tax (IGST), from interstate purchases.
  • Central Tax (CGST), from the central share on intrastate transactions.
  • State or Union Territory Tax (SGST/UTGST), from the state share on intrastate transactions.

The separation exists because GST revenue is shared between the central and state governments. Keeping the buckets distinct prevents credit meant for one from paying the other’s dues, and every entry links back to a specific invoice and return so the trail can be followed either way.

How Credit Reaches the Ledger

Paying tax on a purchase is not enough. Section 16 of the CGST Act lists four conditions, and all four must be satisfied before credit lands in your ledger:

  • A valid tax invoice or debit note from a registered supplier, showing the supplier’s GSTIN, description, and tax charged.
  • Actual receipt of the goods or services. For goods delivered in installments, credit is available only after the last installment arrives.
  • The supplier has actually deposited the tax with the government. If they collected but never paid, your credit is at risk.
  • You have filed your own return under Section 39.

There is a hard deadline. Credit for an invoice cannot be claimed after the due date of the September return following the financial year the invoice belongs to, or after the annual return for that year is filed, whichever is earlier.2Government of India. CGST Act Section 16 – Eligibility and Conditions for Taking Input Tax Credit Miss it and the credit is lost.

One trap catches many taxpayers. If you do not pay the supplier the full invoice amount, including tax, within 180 days, the credit already claimed is added back to your output tax liability with interest. You can reclaim it once you eventually pay, but the cash flow hit lasts until then.

The mechanics of the return flow matter here. Form GSTR-2B is auto-generated on the 14th of each month from invoices your suppliers uploaded, and eligible credit from it auto-populates into your GSTR-3B, the summary return where you declare liability and claim credit.3GST Portal. GSTR-3B – Goods and Services Tax Mismatches between what you claim and what GSTR-2B shows trigger a portal notification.

Credits That Cannot Enter the Ledger

Section 17(5) of the CGST Act permanently blocks input tax credit on certain categories, whether or not the purchase is used for business.4CBIC-Tax Information. CGST Act Section 17 The main ones:

  • Motor vehicles with seating capacity of 13 or fewer (including the driver), unless you resell vehicles, transport passengers, or provide driving instruction.
  • Food and beverages, beauty treatments, health services, cosmetic surgery, and club or gym memberships.
  • Works contract services and goods or services used to construct immovable property on your own account, other than plant and machinery.
  • Leave or home travel concessions for employees, unless the employer is legally required to provide them.
  • General insurance, repair, and maintenance for blocked motor vehicles or aircraft, unless they qualify under an exception.

The portal does not stop you from claiming blocked credit. If you claim it and use it, you owe the full amount back with interest of up to 24% per year, so the responsibility to filter these out is yours.

How You Can Spend the Balance

Section 49(5), refined by Rule 88A, sets a strict order for using credit.1CBIC-Tax Information. CGST Act Section 49 Each type of credit first pays its own type of liability, and the buckets between central and state credit stay walled off.5Goods and Services Tax. GST Tutorial – Utilization Principles

IGST credit is the most flexible. It pays IGST liability first, then anything left over can go against CGST and SGST in any order. All available IGST must be exhausted before you touch CGST or SGST.

CGST credit pays CGST first, then IGST. It can never pay SGST or UTGST.

SGST credit pays SGST first, then IGST, but only after CGST credit has been fully used for IGST. SGST can never pay CGST.

The portal enforces this sequence when you file GSTR-3B. Knowing the logic in advance is how you forecast the cash portion of each month’s payment rather than being surprised by it.

What the Balance Cannot Pay

Credit in the ledger only covers output tax on sales of goods or services. Interest on late payments, penalties, late fees, and any other charges under the Act must come from the electronic cash ledger, which holds actual deposits made to the portal.

The 99% Cap Under Rule 86B

If your taxable supplies, excluding exempt and zero-rated ones, cross ₹50 lakh in any month, credit cannot pay more than 99% of your output tax liability for that month. At least 1% has to come from cash.6CBIC-Tax Information. CGST Rules Rule 86B The rule targets businesses running entirely on credit, a pattern used by fraudulent operators.

You are outside the cap if any of the following applies:

  • The proprietor, managing director, or partners paid more than ₹1 lakh in income tax in each of the last two financial years.
  • The business received more than ₹1 lakh in ITC refunds in the preceding financial year, for zero-rated supplies or inverted duty structure.
  • The business has already paid more than 1% of its cumulative output tax liability in cash during the current financial year.
  • The taxpayer is a government department, public sector undertaking, local authority, or statutory body.

When the Department Can Freeze Your Credit

Rule 86A of the CGST Rules lets a tax officer at or above the rank of Assistant Commissioner block the credit in your ledger where there is reason to believe it was improperly claimed. The grounds:

  • The invoice came from a supplier who does not exist or is not operating from the registered address.
  • You claimed credit on an invoice for goods or services you never received.
  • Tax shown on the invoice was never paid to the government.
  • You do not hold the invoice or debit note supporting the credit.

The officer must record reasons in writing. The block stays in place for up to one year, though the Commissioner can lift it earlier if the grounds no longer apply. While blocked, the amount cannot pay any liability, so responding quickly with documentation matters.

Interest on Getting It Wrong

Section 50 of the CGST Act sets two rates depending on the error:7CBIC-Tax Information. CGST Act Section 50

  • Up to 18% per year on tax paid late.
  • Up to 24% per year on credit that was both wrongly availed and utilized.

The trigger for the higher rate is utilization. Claiming credit you were not entitled to but never using it does not attract the 24% figure. The moment that credit offsets an output liability, the higher rate applies, running from the date of utilization until the amount is paid back. Catching the mistake before you file is what keeps the cheaper rate.

Getting Unused Credit Refunded

Accumulated credit can be refunded under Section 54 of the CGST Act in only two situations:8GST Council. Refund of Unutilised ITC

  • Zero-rated supplies made without payment of tax, meaning exports or supplies to a Special Economic Zone under a bond or Letter of Undertaking. The accumulated input tax credit is refundable.
  • Inverted duty structure, where the tax rate on your inputs is higher than on your outputs, so credit builds up faster than you can use it.

Refund is not available if the exported goods carry an export duty, or if you have already claimed drawback on the central tax component. Construction services are excluded from the inverted duty structure refund. If you have been prosecuted for tax evasion exceeding ₹2.5 crore in the preceding five years, provisional refund is not granted.

Viewing the Ledger on the GST Portal

Checking your balance takes under a minute. After logging in, go to Services, open Ledgers from the dropdown, and click Electronic Credit Ledger.9Goods and Services Tax. Electronic Credit Ledger Pick a date range, view the statement, and every credit and debit entry appears broken down by IGST, CGST, and SGST sub-accounts. Reviewing it before you file each return period is how discrepancies get caught early rather than in a demand notice arriving months later with interest already running.
