GST turnover, banking turnover and ITR turnover: why the three numbers differ

Updated September 2026 2 min read

What each number is

• GST turnover — the value of taxable supplies you have reported in your GST returns. It counts sales when invoiced, not when paid, and excludes anything outside GST.
• Banking turnover — the credits actually landing in your current accounts. It counts money when received, includes advances, and excludes anything paid in cash.
• ITR turnover — the revenue figure in your income tax return and financial statements, on an accrual basis.

Why they legitimately differ

All three can be correct and still not match:

• Timing. An invoice raised in March and paid in May is in one year for GST and ITR, another for banking.
• Exempt or zero-rated supplies sit outside GST turnover but inside ITR turnover.
• Cash sales appear in ITR but not in banking.
• Advances received appear in banking before they appear anywhere else.
• Multiple accounts split banking turnover across statements the lender has not seen.

What lenders accept

A variance of ten to twenty per cent between the three is normal and rarely questioned hard. Beyond thirty per cent, expect a conversation. Beyond fifty per cent, most lenders will size the loan on the lowest number, because that is the conservative reading — and that lowest number is usually the one you least wanted them to use.

How to handle a real gap

Do not hope it goes unnoticed. Reconciliation is one of the first things an underwriter does.

• Give every account statement upfront if the business banks in more than one place.
• Prepare a one-page reconciliation showing the bridge from GST turnover to banking turnover to ITR turnover. Underwriters value this enormously and it is rarely provided.
• Explain cash sales honestly where they exist. Lenders understand cash businesses; they just lend against what they can verify.
• Bring GST filings up to date if they are behind. Gaps in filing cost real eligibility.

The businesses that get funded quickly are not the ones with perfect numbers. They are the ones whose numbers are explained before anyone has to ask.
