This webpage provides information on IRAS’ audit and enforcement efforts, and shares some recent audit cases and the taxes and penalties imposed on businesses found to be non-compliant. It also explains the common GST errors and compliance issues that businesses should avoid.

IRAS conducts regular GST audits using a risk-based approach to select businesses for review. In FY2024/2025, more than 2,800 GST audits were completed across various industries, resulting in a recovery of $205 million, including penalties.

Businesses, regardless of size or type (e.g. sole-proprietors, partnerships, corporates), are at higher risk of GST errors and penalties if they lack proper oversight of their GST compliance. Conversely, businesses with strong GST governance can avoid costly mistakes.

Key elements of good GST compliance include personnel with sound GST knowledge, effective records management, robust internal controls and systems, and regular reviews.

IRAS shares selected audit cases and compliance programmes to illustrate common GST errors and compliance gaps, enabling other GST-registered businesses to proactively avoid these mistakes and make voluntary disclosures to IRAS if similar errors have been made. Voluntary disclosures incur no penalty or lower penalties than errors uncovered by IRAS.

Furthermore, individuals can report suspected malpractices via this form. A reward, equivalent to 15% of the recovered tax (capped at $100,000), is available upon request if the provided information and/or documents lead to the recovery of lost tax.

 

The following are examples of non-compliance detected from recent IRAS GST audits:

FY 2024/2025 Case Highlights

Case 1: Failure to display GST-inclusive prices

Company A has repeatedly failed to display GST-inclusive prices on its signages showing car park rates and wheel-clamp release fees at various car park sites on multiple occasions.

 

For these repeated offences, a penalty of $5,000 was imposed on Company A. 


GST-registered businesses must show GST-inclusive prices on all price displays to the public. Prices that are quoted, whether written or verbal, must be GST-inclusive as the public needs to know the final price they have to pay upfront. If both GST-inclusive and GST-exclusive prices are displayed, the GST-inclusive price must be displayed at least as prominently as the GST-exclusive price.

An exception is granted to hotels and food & beverage (F&B) establishments that impose service charge on their goods and services. They are not required to display GST-inclusive prices to ease their operations. However, they must show a prominent statement informing customers that the prices displayed are subject to GST and service charge.

Failure to comply with the price display requirements can result in a fine of up to $5,000.

Case 2: Non-genuine input tax claims and corresponding zero-rated supplies

Company B claimed to have purchased storage devices (e.g. microSD cards and flash drives) and camera add-on accessories from newly incorporated GST-registered suppliers to be sold to ready customers overseas assigned by Person C. Company B then claimed GST refunds incurred on the purchases and reported the onward supply as its zero-rated supplies. For these back-to-back purchases and sales, Company B was promised a pre-determined profit margin with ready customers; it was also not required to hold inventory. Company B was not vigilant to the too-good-to-be-true deal and did not perform due diligence checks on the suppliers. Subsequently, it was found to be involved in a Missing Trader Fraud arrangement and had its input tax claims disallowed and zero-rated supplies nullified.

 

As a result, Company B had to repay more than $10 million of input tax previously claimed and penalties.


IRAS identifies Missing Trader Fraud arrangements (“MTF”) to be a key compliance risk area and conducts extensive audits and investigations on businesses and individuals involved in such arrangements. Businesses found to be involved in MTF arrangements will be held accountable and may face consequences including denied input tax claims, penalties and cancellation of their GST registration.  To protect themselves, businesses are advised to be alert and avoid participating in any arrangement that is organised with the intention to defraud GST, knowingly or not.

MTF masterminds, co-conspirators and syndicate members who participate in MTF arrangements are liable to imprisonment of up to 10 years and/or fine of up to $500,000 upon conviction. Current or former sole-proprietors, partners or directors of business entities who are involved in MTF arrangements will be liable to an imprisonment of up to 12 months and/or a fine of up to $50,000 upon conviction.

IRAS will not hesitate to take decisive actions against businesses engaging in fraudulent activities, including investigating and prosecuting those intentionally making fictitious tax declarations. For recent prosecution cases related to tax crime, please refer to this section on our website.

 

Case 4: Incorrect GST treatment on supply of media sales

Company F is a game developer who also supplies media sales (advertising spaces) within its game applications. Company F was found to have made several errors including the incorrect zero-rating of advertising spaces within its game applications. Although the GST treatment of media sales has changed with effect from 1 Jan 2022, Company F continued to determine if its sales should be standard-rated or zero-rated based on where the advertisements were circulated. Under the new GST treatment from 1 Jan 2022, Company F should rely on the belonging status of the contracting party and the party directly benefiting from the sale of the advertisement spaces to determine the GST treatment. Hence, Company F had wrongly zero-rated its supply of media sales to Company G who belongs in Singapore.

Following IRAS’ audit, a total of more than $2 million of GST and penalties was recovered from Company F for the errors made.

 

With effect from 1 Jan 2022, the GST treatment of media sales will no longer depend on the place of circulation of the advertisement. Instead, the supply of media sales will be zero-rated under section 21(3)(j) if the supply is contractually made to an overseas person and directly benefit an overseas person and/or a GST-registered person belonging in Singapore. The service will not be regarded as directly in connection with the advertising media in circulation nor the subject matter of the advertisement.

Case 5: Poor record keeping and failure to account for GST on the lease of furniture and fittings

Person H is a sole proprietor who is in the business of providing manpower services. Due to poor record keeping practices, Person H had failed to account for output tax on the sales relating to some invoices kept in a separate file. She also did not maintain valid tax invoices to support several of her input tax claims. In addition, Person H carried on a property leasing business where she failed to account for output tax on the lease of furniture and fittings in a residential property.

 

For these errors, a total of close to $400,000 of GST and penalties was recovered from Person H.

 

Record Keeping Requirements

Businesses are mandated by tax laws to maintain comprehensive and accurate business records, including but not limited to receipts, invoices, bank statements, and accounting ledgers, for a minimum of 5 years. It is crucial for businesses to establish a robust record-keeping system to substantiate their tax declarations with the necessary documents.

Leasing of residential property with furniture and fittings


If you are carrying on a leasing business and let out a furnished residential property, only the bare rental of the residential property is exempt from GST and you must charge GST on the supply of movable furniture and fittings.

 

However, fixtures such as built-in cabinets and wardrobes, kitchen and sanitary wares, wall-mounted air conditioners that are attached permanently to the residential property can be exempted from GST together with the property.

FY 2023/2024 Case Highlights

Case 1: Incorrect GST treatment of counter-supplies / barter trade

Company A (‘Co. A’) trades in fuels and provides intercompany services. Co. A sells and buys from Company B (‘Co. B’). Both are GST-registered businesses. Under a one-off business arrangement, both companies agreed to net off their respective supplies whereby Co. A issued a credit note to Co. B for the net difference on the purchases made from Co. B. Co. A reported the credit note in its GST return by reducing its output tax liability, and its routine GST processes did not detect this irregularity.

Following IRAS’ audit, both companies eventually revised the documentation issued for the counter-supplies and rectified the output tax that was under-accounted.

The output tax shortfall and penalties of close to $5 million was recovered from Co. A and Co. B was also required to account for output tax on its supplies to Co. A in full.

Every GST-registered business must account for GST on its taxable supplies. Co. A and Co. B, as separate GST-registered entities, are required to levy GST on the full selling price of their goods (and/or services) and issue tax invoices to each other. Subsequently, Co. A and Co. B need to report the output tax based on their respective gross value of goods sold and can claim input tax on their purchases, subject to the input tax claiming conditions.

Errors similar to those outlined in Cases 1 and 2 (detailed below) often result from deficiencies in the businesses' GST processes, such as inadequate oversight of tax classification for sales and purchases, lack of GST training for staff, or misapplication of tax laws.

Hence, it is crucial for businesses to provide regular GST training and updates for their staff and establish handover procedures to ensure continuity of GST knowledge and control practices. This is particularly vital for businesses with complex transactions. Additionally, businesses should implement internal procedures to flag exceptional transactions for further review and regularly reassess internal controls and systems to identify and address potential gaps. More information on IRAS’ Voluntary Compliance Initiatives can be found here.

Case 2: Failure to account for GST on services procured from overseas suppliers and other GST errors

Company C (‘Co. C’) is a financial institution. Co. C was found to have made several errors including the omission of output tax on the recovery of expenses from local related companies, overclaiming of input tax and omission of output tax for overseas purchases subject to Reverse Charge. These errors occurred as a result of staff unfamiliarity with new business transactions and Reverse Charge rules, and misapplication of GST treatment for the recovery of expenses. An error also arose from incorrect GST tax coding in the accounting system.

For these errors, a total of close to $3 million of GST and penalties was recovered from Co. C.

Reverse Charge

Since 1 Jan 2020, the Reverse Charge mechanism mandates that GST-registered businesses account for GST on services procured from overseas if the purchaser is not entitled to full input tax credit. This was implemented to ensure equal treatment of all services consumed in Singapore, irrespective of their origin.

As of 1 Jan 2023, the reverse charge has been expanded to include the purchase of low-value goods. This requirement applies to all low-value goods, regardless of whether they are purchased from local or overseas suppliers, electronic marketplaces, or redeliverers, and irrespective of the suppliers' GST registration status.

Recovery of expenses

Businesses frequently recover a portion of expenses from related or third parties. The GST treatment varies based on whether the expense recovery is classified as a reimbursement or a disbursement. Hence, it is essential for businesses to discern between reimbursements and disbursements and apply the appropriate GST treatment accordingly.

Case 3: Failure to produce supporting documentation for input tax claims

Company D (‘Co. D’) trades in computer hardware and peripheral equipment. Majority of Co. D’s input tax on purported purchases of goods from businesses suspected to be involved in Missing Trader Fraud. Co. D could neither provide complete details of these purchases nor able to produce the purchase documentation (e.g. tax invoices) to substantiate its input tax claims. Additionally, Co. D also omitted to account for output tax for certain taxable supplies.

As a result, Co. D had to repay more than $5 million of input tax wrongfully claimed and output tax that was omitted.

 

Businesses are mandated by tax laws to maintain comprehensive and accur ate business records , including but not limited to receipts, invoices, bank statements, and accounting ledgers, for a minimum of 5 years. It is crucial for businesses to establish a robust record-keeping system to substantiate their tax declarations with the necessary documents. Additionally, businesses should ensure that their internal record-keeping processes are well-documented and easily transferable in the event of staff changes handling GST matters.

Furthermore, staff at all levels and functions should be educated and trained to identify indicators of Missing Trader Fraud (MTF), perform due diligence checks, and respond to the risks and results of these checks to avoid being involved in MTF, which can significantly impact the business.

Case 4: Fictitious input tax claims

Company E (‘Co. E’) trades in mobile phones. Co. E had claimed a refund of the GST incurred on the purchase of goods from Company F (‘Co. F’). Subsequent audit findings showed that Co. F did not sell any goods to Co. E. The business arrangement and the documents provided by Co. E could not conclusively support Co. E’s purported transactions with and payments to Co. F.

Hence, the refund claim of over $7 million was disallowed.
