The Deduction Cap Most Employers Only Discover at Tax Filing Time
Singapore employers who provide medical benefits to staff, whether through direct reimbursement, a company clinic panel, or an insured group medical plan, generally assume the cost is a straightforward deductible business expense. It usually is, but only up to a cap. Under the Income Tax Act 1947, medical expenses are deductible against a company’s income only up to 1% of total employee remuneration for the year, or up to 2% if the company provides qualifying portable medical benefits or contributes under the Additional MediSave Contribution Scheme (AMCS). Any medical expense above the applicable cap is simply non-deductible, added back in the tax computation like any other disallowed expense.
This cap catches out a surprising number of otherwise well-run finance teams, usually because nobody re-checks the calculation when the company gives out a new medical benefit, or when headcount and remuneration shift significantly year on year.
How the 1% Base Cap Works
The base position is that medical expenses (this includes reimbursed medical consultation and treatment costs, medical insurance premiums the company pays, and similar staff medical benefits) are deductible up to 1% of the company’s total employee remuneration for the relevant year. Total employee remuneration for this purpose is a broad figure: it generally includes basic salary, bonuses, allowances and other cash and non-cash remuneration paid to employees, not just base pay. A company that under-calculates this base figure (for example, by only counting basic salaries and leaving out bonuses) will understate its own cap and may over-restrict a deduction it was actually entitled to claim in full.
How to Qualify for the Higher 2% Cap
The cap rises to 2% of total employee remuneration where the company does one of the following:
- Provides employees with portable medical benefits, such as a Portable Medical Benefits Scheme (PMBS) or a Transferable Medical Insurance Scheme (TMIS) arrangement, or an approved plan such as MediShield Life-integrated coverage; or
- Makes contributions on behalf of employees under the Additional MediSave Contribution Scheme (AMCS).
The policy intent behind the higher cap is to encourage employers to give staff medical benefits that continue with the employee even if they change jobs, rather than benefits tied entirely to continued employment with one company. Employers who are already close to or above the 1% cap should specifically check whether restructuring their medical benefit as a portable scheme, rather than a standard employer-administered reimbursement plan, would unlock the higher 2% threshold without materially changing the underlying cost to the business.
Worked Example
| Item | Amount (S$) |
|---|---|
| Total employee remuneration for the year | 2,000,000 |
| 1% cap (no portable medical benefits) | 20,000 |
| 2% cap (qualifying portable medical benefits or AMCS) | 40,000 |
| Actual medical expenses incurred | 32,000 |
| Deductible amount if only 1% cap applies | 20,000 (S$12,000 disallowed) |
| Deductible amount if 2% cap applies | 32,000 (fully deductible) |
The S$12,000 difference in this example is not lost forever in every case, since it depends on how the excess is treated, but as a starting position any amount above the applicable cap is added back as a non-deductible expense in the company’s tax computation for the year, increasing the company’s chargeable income.
Where This Interacts With Other Filings
The medical expense cap calculation should be done as part of the annual tax computation prepared alongside the company’s corporate tax filing, and reconciled against the figures used for IR8A and Auto-Inclusion Scheme reporting, since both draw on the same underlying payroll and benefits data. Finance teams preparing the annual computation should pull total remuneration figures directly from the payroll system rather than estimating them, and should confirm with HR whether any medical benefit introduced or changed during the year affects whether the company qualifies for the 1% or 2% cap.
Frequently Asked Questions
Does the cap apply per employee or across the whole company?
The cap is calculated on total employee remuneration across the company for the year, then compared against total medical expenses across the company; it is not calculated separately for each individual employee.
Are medical expenses for directors included?
Generally yes, where the director is also an employee of the company and the remuneration is included in the total employee remuneration figure; the specific tax treatment can vary depending on how the director is engaged, so this should be checked against your own facts.
What happens to the disallowed excess?
Amounts above the applicable cap are added back as a non-deductible expense in the corporate tax computation for the year in which they are incurred.
Can a company qualify for the 2% cap partway through the year?
The qualifying condition (portable medical benefits or AMCS contributions) generally needs to be assessed for the year as a whole; introducing a qualifying scheme partway through the year should be discussed with your tax adviser to confirm the correct treatment for that year.
