Books of Account under explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Section 128 is the accounting-records provision of the Companies Act, and it says four things: keep proper books, at the registered office, on an accrual, double-entry basis, for eight years.
Then it does something unusual — it makes named individuals personally liable for the failure. Not the company, not the board generally. The MD, the whole-time director in charge of finance, the CFO, or whoever the Board specifically charged.
If your company has none of those, read the penalty section carefully.
Books at the registered office — or anywhere in India by Board decision, with AOC-5 filed within seven days. Electronic is fine, but your accounting software must have an unremovable audit trail, and the back-up must be on servers physically in India, daily. Eight financial years of retention. And the fine is personal: ₹50,000 to ₹5,00,000.
The obligation
Every company must prepare and keep, at its registered office, books of account, other relevant books and papers, and financial statements for every financial year that give a true and fair view — including of any branch offices — kept on an accrual basis and double-entry system.
The proviso lets you keep them elsewhere in India by Board decision. But then: file Form AOC-5 within seven days of that decision, giving the full address.
Seven days is genuinely short and it's routinely missed. If your accounts live at the CFO's office, the auditor's premises, or a shared services centre rather than at the registered office, AOC-5 is due within a week of the Board resolution — not at year end.
"Books of account" covers records of all money received and expended and the matters those relate to; all sales and purchases of goods and services; the assets and liabilities; and the cost items prescribed under Section 148 where cost records apply.
Branch offices are covered if proper books for the branch's transactions are kept at that branch, and periodic summarised returns are sent to the registered office or the other place.
Electronic books, and the audit trail
Books may be kept in electronic mode, on conditions:
- they must remain accessible in India and usable for later reference;
- they must be retained in the format originally generated, sent or received — or one that presents the information accurately — and remain complete and unaltered;
- information received from branches must not be altered, and must show what was originally received;
- the records must be displayable in legible form;
- there must be a proper system for storage, retrieval, display and printout, and the records must not be disposed of or rendered unusable unless the law permits;
- a back-up must be kept on servers physically located in India, daily — including where the books are maintained on cloud or outside India.
And the audit trail. Every company using accounting software must use only software that records an audit trail of every transaction, creates an edit log of every change with the date, and ensures the audit trail cannot be disabled.
Your auditor reports on it — whether the software had the feature, whether it operated throughout the year for all transactions, whether it was tampered with, and whether the audit trail has been preserved as the retention rules require.
That "throughout the year" wording is the one that produces qualifications. Software switched on in month four fails it.
One more filing: intimate to the Registrar annually, with the financial statements, the name of the service provider, its IP address, its location, and where the books are on cloud, the address provided by the service provider.
Retention — eight years
Books of account, together with the vouchers relevant to any entry, must be preserved in good order for not less than eight financial years immediately preceding the current one — or for all preceding years, if the company is younger than that.
So in FY 2026-27, the books from FY 2018-19 onwards must survive.
And longer where an investigation is ordered — the Central Government may direct retention for such longer period as it thinks fit.
Inspection by directors
Books and papers maintained within India are open to inspection at the registered office or the other place by any director, during business hours.
Financial information maintained outside India works differently: summarised returns go to the registered office quarterly and stay open for inspection; and where a director asks to see information held abroad, the company must produce it within fifteen days.
The request must come from the director personally — not through a power of attorney holder, agent or representative. That restriction is deliberate and it's enforced.
Officers and employees must give all reasonable assistance with any such inspection.
The penalty is personal
If the managing director, the whole-time director in charge of finance, the CFO, or any other person charged by the Board with complying with Section 128 contravenes it, that individual is punishable with a fine of not less than ₹50,000, up to ₹5,00,000.
Two features worth dwelling on:
The liability is individual and named. It doesn't fall on the company, or on all the directors generally.
It's a fine, not a penalty. So it isn't adjudicated under Section 454, and Section 446B relief doesn't apply — a small company gets no reduction.
And here's the practical point. Where a company has no MD, no WTD in charge of finance and no CFO — which describes most small private companies — the Board should specifically charge a named director with the Section 128 responsibility, by resolution.
Without that, the position is ambiguous and the exposure is diffuse. It's the same five-minute agenda item as naming the officer in default under Section 2(60)(iii), and it belongs in the same board meeting. Officer in default →
