Employment expenses can be deducted from employment income if they are wholly and exclusively incurred in the production of the income in Singapore. These expenses must have been incurred by the employee in carrying out one's official duties, and cannot have been reimbursed by the employer, of a capital/private nature, or incurred on public transport.
Generally, a 250% deduction may be claimed for qualifying donations to approved charities, foundations, and grantmakers.
Life insurance premiums
Life insurance premiums are deductible but subject to certain conditions, and the total deduction (i.e. contributions to the CPF and life insurance premium) is restricted to SGD 5,000.
Interest expense may be deductible, provided it is incurred wholly and exclusively in the production of taxable income. Mortgage interest is, therefore, deductible only where the property concerned yields income.
An individual can deduct annual subscriptions paid to professional institutes or societies in which membership is generally required as a condition of employment.
No deductions are allowed for medical expenses or for any other personal or household expenditure.
Singapore citizens and permanent residents are allowed deductions against their taxable income for contributions made to the CPF or an approved pension/provident fund but subject to the following limits:
- Contributions made up to the limit prescribed in the CPF Act.
- For a self-employed individual, the deduction for contributions made for each year of assessment is restricted to the lower of SGD 37,740 (i.e. CPF contributions up to the specified income ceiling of SGD 102,000) and the CPF contribution rate of 37% applied to the individual's assessable business income.
A deduction for SRS contributions of up to 15% of income (for Singapore citizens and permanent residents) and up to 35% (for foreigners) can be claimed against the income earned in the year in which the contributions are made (subject to income capping rules).
Spouses can no longer elect to transfer qualifying deductions (including excess capital allowances, trade losses, donations, and rental deficits) to each other.
Any unabsorbed trade losses or capital allowances can still be carried forward to future years to be offset against the future income of the taxpayer until the amount is fully utilised, subject to existing rules. Any unutilised donations can also be carried forward to future years to be offset against the future income of the taxpayer, up to a maximum of five years.

- CPF cash top-up relief: Lower of SGD 7,000 per year or the actual amount of cash top-up by the taxpayer or the employer to the taxpayer’s CPF retirement account. The taxpayer can claim a further relief of up to SGD 7,000 for top-ups made to the accounts of one's siblings, parents, parents-in-law, grandparents, grandparents-in-law, and spouse. For the taxpayer’s siblings and spouse, they must have derived income of not more than SGD 4,000. In addition, individuals who make voluntary contributions to their own CPF healthcare accounts (Medisave) will be allowed tax relief. For year 2017, the relief is up to a cap of SGD 37,740 less mandatory contributions for year of assessment 2018 (income year 2017).
Additional reliefs are granted for dependant great-grandparents and handicapped siblings.
With effect from the year of assessment 2018, personal income tax (PIT) reliefs are subject to a cap of SGD 80,000 per year of assessment.
Where an individual carries on a trade, business, profession, or vocation, deductions are allowed for all outgoings and expenses incurred wholly and exclusively in the production of the income being assessed (except expenses specifically prohibited under the Income Tax Act), including capital allowances (fiscal depreciation) on most fixed assets except for land and non-industrial buildings.
An approved angel investor who commits an equity investment of at least SGD 100,000 in a qualifying start-up between 1 March 2010 and 31 March 2020 will be allowed to deduct 50% of the investment at the end of the second year of holding of the investment. The deduction is subject to a cap of SGD 500,000 of investment per year of assessment.
Business losses and unutilised capital allowances may be offset against other sources of income such as employment, interest, dividend, and rental income in the same year. Any remaining unabsorbed losses and capital allowances can be carried forward, subject to certain conditions.
Current year unutilised business losses and capital allowances of up to SGD 100,000 can also be carried back to the year of assessment immediately preceding the year of assessment in which the loss and capital allowance arose.
