17% - beginning,
not the whole calculation

01

Territorial features without a simple offshore rule

Singapore taxes income arising in or originating in Singapore and certain foreign income when received in Singapore. First, the flow and source are classified, then residence, exemption, foreign tax credit and contract.

Tax authority

Inland Revenue Authority of Singapore — IRAS

Basis

Chargeable income for the corresponding Year of Assessment

Capital gains

There is no general capital gains tax, but income from trading is taxed based on the facts

Dividends

Singapore company dividends are usually one-tier tax exempt for the participant

Treaties

Benefits require applicable DTA and verified residency

02

The 17% rate is reduced only according to the rules

Corporate income tax is 17% of normal chargeable income. A qualifying new company can apply a start-up tax exemption, the rest can apply a partial tax exemption. Annual rebates and grants vary by budget, so they are calculated separately for a specific YA and are not built into the long-term model as a permanent rate.

Headline rate

17%

Start-up exemption

For the qualifying company and the first three YAs; conditions are checked

Partial exemption

Applies to part of normal chargeable income

Incentives

EDB, Enterprise Singapore and sector regimes require approval and substance

Effective rate

Depends on the composition of income, benefits and expenses

03

Control and management is more important than the place of incorporation

A company is considered Singapore resident tax when the control and management of the business is carried out in Singapore. IRAS evaluates strategic decisions and board process, and not just the registered office or resident director. A Certificate of Residence is requested for a treaty claim and is supported by the facts of the relevant year.

04

Foreign income is analyzed for each flow

A Singapore tax resident company can obtain an exemption for foreign-sourced dividends, foreign branch profits and foreign-sourced service income received in Singapore if the statutory conditions are met: income subject to tax, foreign headline rate not lower than 15% and benefit test. If an exemption is not available, the foreign tax credit is checked.

Specified income

Dividends, branch profits, service income

Subject to tax

Income must meet foreign taxation conditions

Headline rate

At least 15% in the relevant foreign jurisdiction

Beneficial

Comptroller should consider the release beneficial

Evidence

Tax vouchers, returns, incentive approval and tracking schedule

05

GST 9% and separate supplies card

GST-registered business charges 9% on local taxable supplies if the transaction is not zero-rated or exempt. Mandatory registration usually arises with taxable turnover in excess of S$1 million according to a retrospective or prospective test. Export of goods and international services require precise qualifications and supporting documents.

06

Deduction follows production of income

The expense must be wholly and exclusively incurred in the production of income and not fall under capital/private restrictions. For fixed assets, capital allowances apply, for bad debts, financing, R&D and IP - separate conditions. Tax computation is carried out separately from accounting profit.

07

Arm's length is documented before the IRAS request

Related-party goods, services, IP, loans, guarantees and cash pooling are assessed according to the arm’s length principle. Section 34F documentation is usually required if gross trade/business revenue exceeds S$10 million or documentation was required in the previous basis period unless an exception applies. If requested by IRAS, the file will be submitted within 30 days.

Documentation

Group overview + entity and transaction analysis

Timing

No later than the deadline for filing corporate tax return

Retention

At least 5 years from the end of the basis period

RPT reporting

Form for Reporting RPT above S$15 million

Defence

Contracts, FAR, method, comparables and actual conduct

08

Payment to a non-resident is verified before transfer

Interest, royalties, technical/management services, rent of movable property and other payments to non-residents can create a withholding tax. The nature of income, place of performance of services, permanent establishment, beneficial ownership and DTA are analyzed before the payment date and contractual gross-up.
