Transfer Pricing in Singapore
When companies operate across different countries or have many related entities under the same group, they often buy and sell goods, services, or intellectual property from one another. The prices used in these related‑party dealings are known as transfer prices.
In Singapore, the Inland Revenue Authority of Singapore (IRAS) requires all businesses to follow the arm’s length principle when setting these prices. This helps ensure that profits are correctly taxed in the places where real economic activity happens.
Although transfer pricing rules may sound technical or complicated, understanding the basics can help companies stay compliant, avoid penalties, and reduce the risk of double taxation. This blog post explains the key principles, using only verified information from IRAS.
1. What Is Transfer Pricing?
Transfer pricing refers to the prices charged between related companies within the same group. These can include:
- Buying or selling goods
- Providing services
- Using or transferring intangible assets (e.g., patents, trademarks)
- Lending or borrowing funds
- Any other transactions between related parties
Two parties are considered related if:
- One controls the other, or
- Both are under the common control of a third party
This applies whether the control is direct or indirect.
Even a branch and its head office are considered related parties.
2. Why Does IRAS Care About Transfer Pricing?
IRAS follows the internationally accepted arm’s length principle. This means the transfer price used between related parties should be similar to the price that would be charged between independent, unrelated parties under the same or comparable circumstances.
Why is this important?
Because transfer prices affect how much profit is reported in Singapore versus in other countries. IRAS wants to ensure:
- Singapore businesses report the correct profit
- Tax is paid in the country where value is created and work is actually performed
- Companies do not artificially shift profits across borders
A proper transfer pricing approach ensures fair taxation and avoids disputes with foreign tax authorities.
3. How to Apply the Arm’s Length Principle: IRAS’ 3‑Step Method
IRAS recommends a three‑step approach to determine whether a transfer price is at arm’s length.
Step 1: Conduct a Comparability Analysis
This involves comparing the related‑party transaction to similar transactions between unrelated parties.
You look for similarities in:
- Market conditions
- Functions performed
- Risks assumed
- Assets used
- Contract terms
If unrelated businesses operate in comparable ways, their pricing can help guide your arm’s length price.
Step 2: Identify the Most Appropriate Transfer Pricing Method
There are several internationally recognised methods, and the choice depends on the nature of the transaction. You also identify the tested party, which is usually the simpler party in the transaction the one with fewer complex functions or unique assets.
Step 3: Determine the Arm’s Length Result
Finally, you use the chosen method and comparable data to calculate an arm’s length price or range.
This becomes the basis for your related‑party pricing.
4. Transfer Pricing Adjustments and the 5% Surcharge
If IRAS finds that a company’s related‑party pricing is not at arm’s length, and this leads to understated profits (or overstated losses) in Singapore, IRAS has the power under Section 34D(1A) of the Income Tax Act 1947 to adjust the taxpayer’s profit.
Introduction of the 5% Surcharge
Starting from the Year of Assessment (YA) 2019, IRAS imposes a 5% surcharge on the amount of any transfer pricing adjustment made.
Important points:
- The 5% surcharge applies even if no additional tax is payable after the adjustment.
- IRAS may reduce or waive the surcharge if there is good cause.
This rule encourages businesses to apply the arm’s length principle properly and maintain adequate documentation.
5. Transfer Pricing Documentation: What It Is and Why It Matters
Businesses must prepare and keep contemporaneous transfer pricing documentation. This documentation proves that the prices used in related‑party transactions are based on the arm’s length principle.
What counts as contemporaneous?
Documentation is considered contemporaneous if it is:
- Prepared before or at the time the transactions take place, or
- Prepared no later than the filing due date of the Income Tax Return for that financial year
The documentation should rely on the latest information and data available at the time the pricing decisions were made.
Why documentation is important
Good documentation helps:
- Show IRAS that your transfer prices are correct
- Reduce the risk of disputes
- Avoid double taxation (when both Singapore and another country tax the same income)
- Support your position if IRAS or a foreign tax authority asks questions
If you cannot show that your prices are at arm’s length, IRAS may adjust your profits, and you may face penalties or tax complications.
6. Who Must Prepare Transfer Pricing Documentation?
From YA 2019, documentation must be prepared under Section 34F of the Income Tax Act 1947, if certain conditions are met.
Even if you do not fall under those conditions, IRAS encourages you to prepare documentation anyway to manage your transfer pricing risks.
(Document details and thresholds are governed by IRAS, but your request specifies using only the exact text provided, so no additional criteria are added here.)
7. Penalties for Not Complying with Documentation Rules
From YA 2019, businesses may face a fine of up to S$10,000 for any of the following:
- Not preparing transfer pricing documentation within the required timeframe
- Not meeting the content requirements
- Not submitting documentation within 30 days when IRAS requests it
- Not keeping documentation for at least five years
- Submitting false or misleading documentation
These penalties highlight the importance of getting documentation right and staying organised.
8. Reporting Related Party Transactions (RPT)
From YA 2018, companies must complete the Form for Reporting Related Party Transactions (RPT) if the total value of related‑party transactions disclosed in the financial statements exceeds S$15 million.
What counts toward the S$15 million?
The total value includes:
- All amounts received/receivable from related parties and all amounts paid/payable to related parties in the income statement
- Excludes:
- Compensation to key management personnel
- Dividends
- Excludes:
- Year‑end balances of:
- Loans due to/from related parties
- Non‑trade amounts due to/from related parties
The form helps IRAS assess a company’s transfer pricing risks more effectively.
Changes from YA 2020
From YA 2020 onwards:
- The form is integrated into the Corporate Income Tax Return (Form C)
- If your company’s related‑party transactions exceed S$15 million, you must:
- Indicate “Yes” in Item 31 of Form C
- Fill in the details in the Related Party Transactions tab
For YA 2018 and YA 2019
- The RPT Form must be completed separately and filed together with Form C
9. Why Transfer Pricing Compliance Matters
For many businesses, transfer pricing may feel like just another tax requirement. However, getting it wrong can lead to:
- Additional tax assessments
- The 5% surcharge
- Penalties
- Double taxation
- Time‑consuming disputes with local or foreign tax authorities
By following IRAS guidelines and maintaining proper documentation, companies can:
- Clearly show how prices are determined
- Reduce risk during tax reviews
- Stay compliant
- Ensure that taxes are paid fairly and correctly
10. Key Takeaways
If your business has related‑party transactions, it is important to remember:
✔ You must price your transactions using the arm’s length principle
Prices should be similar to what unrelated parties would charge each other in comparable situations.
✔ You must prepare contemporaneous transfer pricing documentation
This shows how your prices were set and why they are reasonable.
✔ You may face adjustments and a 5% surcharge if prices are not at arm’s length
This applies even if the adjustment does not increase your tax liability.
✔ You may face a fine of up to S$10,000 for not complying with documentation rules
✔ You must complete the RPT form if your related‑party transactions exceed S$15 million
From YA 2020, this is included inside Form C.
