Transfer pricing rules in Singapore ask one thing: price deals with related parties as you would with a stranger. IRAS, the tax authority, checks this and requires a written file once a taxpayer's gross revenue passes S$10 million. Checked on .
What does transfer pricing mean in Singapore?
IRAS says two parties are related if either controls the other, or both are under the common control of another party, directly or indirectly. Branches and head offices count as related. If your Singapore company buys goods from a sister company in Hong Kong, borrows from its parent in the UK or pays a group service fee, those are related-party transactions.
IRAS follows the arm's length principle. Transfer prices should match what unrelated parties would have charged under the same or comparable circumstances. IRAS says profit should be taxed where the real economic activity happens and value is created.
How should you set an arm's length price?
IRAS recommends a 3-step approach:
- Comparability analysis. Find deals between unrelated parties that look like yours.
- Method and tested party. Pick the most appropriate method. IRAS names the comparable uncontrolled price and the transactional net margin method as examples.
- Arm's length result. Work out the price or margin from steps one and two.
The decision on method belongs in your documentation, with reasons. Many companies ask a tax agent to do this step.
Who must keep transfer pricing documentation?
Under Section 34F of the Income Tax Act, you must prepare documentation if either of these is true:
- Your gross revenue from trade or business is more than S$10 million for the basis period, or
- You had to prepare documentation for the basis period just before.
Exemptions are set out in the Income Tax (Transfer Pricing Documentation) Rules. They cover some domestic related-party deals at the same tax rate, and some deals whose value is below set thresholds. This page does not repeat those thresholds. Read the Rules on Singapore Statutes Online or ask your tax agent.
If you are under the revenue line, IRAS still encourages documentation to manage your risk. A short file now saves time if an overseas tax office asks about the same deal.
What goes in the documentation and when is it due?
| Point | IRAS rule |
|---|---|
| Content | An overview of the group's businesses relevant to Singapore, plus detail on your business and related-party deals, including a functional analysis and a transfer pricing analysis |
| Deadline | By the filing due date of the Income Tax Return |
| Submission | Not filed with the return. Give it to IRAS within 30 days of a request |
| Retention | At least 5 years from the end of the basis period in which the deal took place |
| Refresh | May be refreshed once every 3 years if details stay accurate, with a simplified document when conditions are met |
IRAS accepts documentation as contemporaneous if it was done before or at the time of the deal, or by the return filing deadline for that financial year. Use the latest data available at the time.
Can you rely on the group's documentation?
Only if it supports your Singapore pricing. IRAS says a Singapore company in a multinational group must still understand how the group policy is applied to its deals, check it matches IRAS guidelines and review it regularly with head office. If the group file lacks the detail the Rules require, you must prepare your own or add to the group file.
For group service charges, IRAS suggests a written contract with the overseas party. It should list the services and how the charge is worked out, and someone should check the terms before each bill is paid.
What are the penalties?
Two separate penalties exist:
- Surcharge. If IRAS adjusts your profit because prices were not arm's length, it adds a 5% surcharge on the adjustment, even where no extra tax results. IRAS may waive all or part of it for good cause.
- Fine. Up to S$10,000 for failing to prepare documentation on time or properly, failing to submit it within 30 days, failing to keep it for 5 years, or giving false or misleading documents.
Without a file, IRAS warns of other consequences, including double taxation if a foreign tax office also adjusts the deal.
What do related-party deals look like in practice?
Some everyday examples a small Singapore company may meet:
- A management fee paid to a parent abroad for admin or IT support.
- A loan from a director's overseas company, with interest charged.
- Stock bought from a sister company that then goes to local customers.
- Staff costs shared between group members.
For each one, ask what an outside party would have charged, then write down how you got the number. IRAS says a single bundled price can be tested too, by looking at what the goods would sell for without the service element. Withholding tax may also apply when you pay interest or royalties to a non-resident, so read withholding tax alongside this page.

If you want a tax agent to review your related-party deals and write the documentation, use the quote form. We pass your request to suitable providers, and they quote their own fees.
