Incentives and income categories
Section 13A covers qualifying income from Singapore-registered ships operating internationally; MSI-AIS under section 13E covers approved international shipping companies. The source lists time/voyage/slot/bareboat charter fees, freight, ship disposal gains, foreign-exchange and risk-management activities, ship management, mobilisation/demobilisation, holding fees and incidental container rental as generally qualifying, subject to the applicable conditions. Other income such as interest falls under the normal rate. In the targeted 2020 review, shipping companies made up 66% of cases with incorrect treatment, not 66% of all shipping companies.
Mistakes 1–3: losses and exempt receipts
Unused losses and allowances of section 13A exempt activities must be disregarded, not shifted to normal-rate income or carried forward. Foreign-ship charter income, including a Singapore ship with suspended registration flying a foreign flag, is not section 13A exempt; only Singapore ships operating outside local waters qualify for that charter exemption. For foreign ships, freight exemption requires goods uplifted from Singapore and operations outside Singapore waters. Prescribed management services require a section 13A(16) qualifying company and its owned or operated Singapore ship under section 13A(1CD) and the 2017 Rules.
Mistakes 4–6: costs and common assets
Directly identified foreign-vessel loan interest belongs to that vessel’s income; a loan financing a wholly exempt vessel offsets only exempt income and is not a common expense. Identify each vessel’s direct costs; if its income is mixed, allocate by that vessel’s turnover. Operating exchange gains and office costs of a wholly exempt shipping operation cannot simply be placed under normal-rate income. Company common costs such as office rent, utilities, stationery and audit fees use an appropriate basis, without allocation to passive interest or dividends. Common-asset allowances use company turnover; mixed-vessel allowances use that vessel’s turnover.
Mistake 7: reflagged ship residue
After a Singapore ship becomes foreign, allowances use residue of expenditure (ROE), not original cost, under section 13A(11), even if allowances were never actually claimed while Singapore-registered. Where notional section 19 allowances are used, calculate both initial and annual notional allowances to establish ROE.
Mistake 8: disposal adjustments
Section 20(1) determines balancing allowance or charge; do not apportion sale proceeds without statutory authority. Balancing allowances follow basis-period vessel turnover between exempt and normal income, or entirely normal-rate where all vessel income is normal-rate. Section 10(4) normally taxes a balancing charge at the normal rate, except its proportion attributable to allowances against sections 13A/13E/13P exempt income, capped by X÷Y×Z: X is exempt-income allowances, Y all allowances during ownership, Z the balancing charge.
Generic errors and recordkeeping
Excess medical expenses above the specified remuneration percentage are added to normal-rate income under section 14(6), not exempt income. Improper claims include holding-company staff’s office rent, private-car costs, non-trade exchange losses, non-trade receivable provisions and unused-leave provisions. Sections 13A(2) and 13E(5) require separate operating accounts for each Singapore and foreign ship to identify income and direct expenses.
Disclosure rules in the audit publication
The source describes section 95 penalties up to twice undercharged tax and possible prosecution. Qualifying voluntary disclosures within one year of the 30 November statutory filing date can have penalties waived; after the grace period the stated reduced rate is 5% per annum. These conditions and incentive provisions reflect the linked audit publication, not an unconditional exemption for all shipping income.
