Mandatory Retention Period for Account Books

Every company keeps a mountain of financial paperwork, invoices, receipts, ledgers, bank statements, and journal entries. But how long is a company actually supposed to hold on to this paperwork before it can be shredded or deleted? This is not a matter of internal preference. The Companies Act, 2013 lays down a specific, mandatory retention period, and getting it wrong can mean real financial and legal trouble for the people running the company.

The legal foundation: Section 128 of the Companies Act, 2013 🔗

The retention requirement comes from Section 128 of the Companies Act, 2013, which deals broadly with how a company must prepare, maintain, and preserve its books of account. Sub-section (5) of this provision is the specific rule that answers our question: for how long must these records be kept?

The section states that the books of account, along with the vouchers relevant to any entry in them, must be preserved in good order for a minimum of eight financial years. This is not a suggestion or a best practice; it is a statutory obligation binding on every registered company, whether private, public, or a one-person company.

The eight-year rule explained 🔗

In simple terms, at any given point, a company must be able to produce its books of account for the eight financial years immediately preceding the current one. So if a company is preparing its accounts for FY 2025-26, it must still have on record the books relating to FY 2017-18 through FY 2024-25, in addition to the current year. Once a financial year moves beyond this eight-year window, the company is generally free to dispose of that year’s records, unless another rule requires otherwise.

What if the company is younger than eight years? 🔗

Newer companies do not get a shorter obligation just because they have not existed for eight years. The law is clear that where a company has been in existence for less than eight years, it must retain the books of account for the entire period since its incorporation. So a company that is three years old must simply preserve every year’s records it has generated so far, since none of it has yet crossed the eight-year threshold.

What exactly counts as “books of account”? 🔗

The retention rule is not limited to a vague idea of “financial records.” The Companies Act gives an inclusive definition covering records of money received and spent, along with the matters to which the receipts and expenditure relate, records of sales and purchases of goods and services, the assets and liabilities of the company, and, where applicable, cost records for companies engaged in production, processing, manufacturing, or mining. This definition is intentionally broad so that no company can argue a particular financial document falls outside its compliance duty.

Vouchers matter just as much as the books themselves 🔗

A detail that is often overlooked is that the eight-year retention rule applies not only to the books of account themselves but also to the vouchers relevant to any entry in them. A voucher is the supporting document, such as a bill, receipt, or invoice, that substantiates a particular transaction recorded in the books. Without these vouchers, an auditor or investigator cannot verify whether an entry in the books is genuine. This is why companies are expected to preserve source documents alongside ledgers and journals, not just the summarised figures.

Where and how must these records be kept? 🔗

Books of account are ordinarily required to be kept at the company’s registered office. However, the Board of Directors can decide to keep them at another location within India, provided the Registrar of Companies is informed through Form AOC-5 within seven days of that decision, as explained in this overview of Section 128 compliance requirements.

Companies are also permitted to maintain their books in electronic form. When records are kept digitally, the law requires that they remain accessible in India for future reference, that they are retained in the format in which they were originally generated or received, and that the information stays complete, unaltered, and traceable in the event any entry is corrected. A backup of electronic records must additionally be kept on servers physically located in India, as clarified in a review of recent amendments to the Companies (Accounts) Rules.

Can the retention period be extended beyond eight years? 🔗

Yes. The eight-year figure is a floor, not necessarily a ceiling. If the Central Government orders an investigation into the affairs of a company under Chapter XIV of the Act, it can direct that the books of account be preserved for a period longer than eight years, for as long as it considers necessary for that investigation. This ensures that a company under scrutiny cannot simply wait out the standard retention window and dispose of potentially relevant evidence.

What happens if a company does not comply? 🔗

Responsibility for maintaining and preserving books of account rests with specific individuals: the managing director, the whole-time director in charge of finance, the Chief Financial Officer, or any other person the Board specifically charges with this duty. If these provisions are contravened, the responsible person is punishable with a fine that is not less than fifty thousand rupees and which may extend to five lakh rupees, according to Section 128(6) of the Act. It is worth noting that an earlier version of this provision also carried a possible term of imprisonment of up to one year, but that clause was removed following the Companies (Amendment) Act, 2020, which decriminalised several minor procedural lapses under company law, as tracked in this annotated reading of Section 128.

Beyond the direct penalty, poor record retention creates a bigger problem during statutory audits. Auditors are required to report whether proper books of account, as mandated by law, have actually been kept by the company. Missing records for any of the mandatory eight years can lead to an adverse remark in the audit report, which affects the company’s credibility with regulators, banks, and investors.

Why does the law insist on eight years specifically? 🔗

This period is not arbitrary. It aligns closely with the broader window within which financial irregularities are typically investigated, reopened, or challenged. For instance, the Companies Act itself provides that books of account cannot be ordered to be reopened for a period earlier than eight financial years immediately preceding the current one, except in narrow, specified circumstances. Keeping the retention rule and the reopening rule in sync means a company is never asked to produce records that it was legally entitled to destroy. It also gives auditors, regulators, and courts a reliable, predictable stretch of history to examine whenever questions about a company’s financial conduct arise.

How this compares with other record-keeping laws 🔗

Students sometimes confuse the Companies Act retention period with requirements under tax law, so it helps to see them side by side.

The overlap between these timelines means most companies end up designing their record-retention policy around the longer eight-year window under company law, since that automatically satisfies the shorter income-tax requirement as well. This kind of layered compliance thinking is a good habit to build early, and platforms supporting business accounting, such as those discussed in this overview of mandatory accounting records, often build retention reminders directly into their systems for exactly this reason.

A quick compliance checklist 🔗

For a company (or a student trying to remember this topic for an exam), the retention rule can be reduced to a few practical points:

• Minimum period: Eight financial years immediately preceding the current one.
• Younger companies: Retain records from the date of incorporation until the eight-year threshold is reached.
• Vouchers included: Supporting documents for every entry must be preserved, not just the ledgers.
• Location: Registered office, or another Indian location approved by the Board and reported via Form AOC-5.
• Electronic records: Must remain accessible in India, unaltered, and backed up on Indian servers.
• Extension: The Central Government can extend the period during an ongoing investigation.
• Non-compliance: Fine between fifty thousand and five lakh rupees for the officer responsible.

This provision might look like a small technical detail buried inside a large Act, but it plays a quiet, important role in corporate governance. It ensures that when a shareholder, auditor, tax officer, or investigator needs to trace how a company’s money moved eight years ago, the trail has not gone cold.

What do you think? If a company shifts to fully digital record-keeping, do you think the eight-year rule is still adequate, or should the retention period be reconsidered for the digital era? And should smaller private companies genuinely face the same eight-year burden as large listed companies?
