A shopping mall landlord asks for an annual gross turnover certificate, but your company is already subject to a statutory audit. It is reasonable to ask: are GTO audits mandatory as well? The short answer is no, not for every business. A GTO audit is usually required because of the terms of a retail lease, not because every Singapore company must complete one under company law.

For tenants with turnover-based rent, however, the requirement can be contractual and time-sensitive. Missing the submission date, using an unapproved auditor, or providing incomplete sales records may lead to disputes with the landlord, additional charges, or delays in finalizing rent.

Are GTO audits mandatory under Singapore law?

A GTO audit is not a universal statutory requirement for companies in Singapore. Whether your company needs one depends primarily on the lease agreement, license agreement, or other contract with the property owner or mall operator.

Many retail leases require tenants to report gross turnover monthly and submit an annual auditor-certified turnover statement. This gives the landlord assurance that turnover rent, also called percentage rent, has been calculated using complete and accurate sales figures. Where the lease contains this requirement, the audit or certification becomes mandatory for that tenant under the contract.

The wording matters. Some agreements require a full GTO audit report from a public accountant. Others ask for an auditor’s certificate, a factual confirmation of annual sales, or agreed-upon procedures. A few may permit an internal management declaration unless the landlord requests further verification. The required work should always be determined from the signed lease and any subsequent addenda.

This is separate from a company’s statutory financial statement audit. A statutory audit considers the financial statements as a whole. A GTO engagement focuses specifically on sales turnover reported for a particular outlet, premises, or lease period. Even if your financial statements have been audited, the landlord may still require a separate GTO report because the scope, timing, reporting format, and definition of turnover can differ.

Why landlords require GTO verification

Turnover rent arrangements are common in shopping centers, food and beverage outlets, lifestyle concepts, and other retail locations. The tenant typically pays a base rent and, where applicable, an additional amount based on a percentage of gross turnover above an agreed threshold.

The landlord needs reliable sales information to calculate the amount due. Since sales data is generated and controlled by the tenant, independent verification helps both parties work from a documented basis. It can also reduce disagreements about matters such as refunds, discounts, delivery-platform sales, vouchers, loyalty points, staff purchases, and sales recorded at another location.

For the tenant, a properly completed GTO audit can be protective as well. It creates an independent record that the reported figures were prepared in accordance with the lease definition. If questions arise later, the tenant has supporting documentation rather than relying on informal explanations or incomplete reports.

When a GTO audit is likely required

The most reliable answer is found in the clauses dealing with rent, gross turnover, records, audit rights, and annual reporting. A requirement may be clearly stated as an obligation to submit a certificate by a fixed date after the financial year-end. In other leases, the landlord may reserve the right to inspect records or appoint an auditor, with the tenant bearing the cost if an underreporting is found.

Pay attention to four practical details:

• The definition of gross turnover. This determines which sales must be included and which deductions are permitted.
• The reporting period. It may follow the lease year, calendar year, or another period that does not match your company’s financial year.
• The required form of report. Landlords may provide a prescribed template or require specified wording from the auditor.
• The deadline and auditor qualifications. The agreement may require a Singapore public accountant or auditor acceptable to the landlord.

A retail tenant should not assume that a report prepared for one mall will be accepted by another. Each landlord may use different definitions, exclusions, and certification formats.

What does a GTO auditor review?

The exact procedures depend on the engagement terms, but the auditor generally compares the gross turnover reported to the landlord with supporting business records. The objective is to assess whether the turnover declaration agrees with records maintained by the tenant and has been prepared according to the lease requirements.

Supporting documents may include point-of-sale reports, daily sales summaries, cash register records, credit card settlement reports, bank statements, accounting ledgers, tax invoices, refund logs, e-commerce reports, delivery-platform statements, and relevant management schedules. For multi-outlet businesses, the auditor may also need evidence that sales have been allocated to the correct leased location.

Exceptions often arise from timing differences or from transactions that need careful treatment. For example, an online order may be paid for through a central website but fulfilled by a specific store. A refund may be processed after the original sale period. A gift voucher may be sold at one time and redeemed later. The lease, rather than a general accounting preference, usually determines how those items affect GTO.

This is why early preparation is more efficient than trying to reconcile a full year of sales shortly before the deadline. Clear monthly records make the final engagement faster, more accurate, and less disruptive to operations.

How to prepare for a timely GTO audit

Start by reading the lease before the reporting period ends. Confirm the due date, required report format, applicable period, and gross turnover definition. If the wording is unclear, obtain clarification from the landlord or managing agent in writing. A small ambiguity about exclusions can become a larger issue once rent calculations are finalized.

Next, reconcile monthly point-of-sale totals to your accounting records. Investigate significant differences promptly. A reconciliation does not need to be complicated, but it should explain differences caused by sales cut-off, refunds, payment processing, outlet transfers, or other identifiable factors.

Keep supporting documents organized by month and by outlet. Businesses using multiple payment channels should retain reports for cash, cards, QR payments, online platforms, and third-party delivery providers. Finance teams should also preserve documentation for unusual transactions rather than attempting to reconstruct explanations months later.

It is sensible to appoint the auditor early, particularly where several outlets have different landlord requirements or where the GTO period ends close to your statutory audit or AGM timetable. Early engagement allows the auditor to identify missing schedules, clarify scope, and plan the work around your reporting deadline.

Common mistakes that create avoidable delays

One common mistake is treating the landlord’s annual GTO form as a simple administrative document. If it requires auditor certification, it must be supported by records that can be tested. Another is using the company’s total revenue without separating sales for the leased premises. Centralized systems can make this difficult unless outlet codes and reporting controls are established from the start.

Tenants may also overlook lease-specific exclusions. For instance, a tenant may assume GST, refunds, staff discounts, delivery charges, or voucher redemptions can be excluded. That may be correct, but only if the lease definition permits it. The reverse can also happen: sales that management regards as non-store revenue may still be included for turnover-rent purposes.

Finally, do not wait until the landlord follows up. Late submission can put unnecessary pressure on finance staff and auditors, especially during busy year-end periods. A competent audit team can work efficiently, but complete records and reasonable lead time remain essential.

Choosing the right support for your GTO requirement

The right auditor should be familiar with the practical differences between statutory financial audits and lease-based turnover verification. Beyond professional qualifications, look for clear communication, a defined document request, realistic timing, and an understanding that retail teams cannot pause daily operations for an audit.

Koh & Lim Audit PAC provides GTO and sales turnover audit support with a focus on accurate work, responsive communication, and timely completion. For tenants managing multiple reporting obligations, a structured approach can reduce last-minute document chasing and help keep landlord submissions on track.

If your lease requires a GTO certificate, treat the requirement as part of your ongoing rent compliance rather than an annual surprise. Maintaining clean monthly sales records and confirming the lease terms early gives your team the best chance of completing the process correctly and on time.
