Every employer running Singapore payroll owes the Skills Development Levy (SDL) on every employee, and most get the floor, the ceiling, or the exemptions wrong. SDL is a mandatory, employer-funded levy on monthly wages, collected by the Central Provident Fund (CPF) Board on behalf of the Skills and Workforce Development Agency (SWDA). The money flows into the Skills Development Fund (SDF), which funds national training. SWDA began operations on 1 July 2026, formed by merging SkillsFuture Singapore (SSG) and Workforce Singapore (WSG), per the SWDA newsroom; the older Workforce Development Agency (WDA) has been defunct since 2016.
What is the SDL rate in Singapore?
SDL is 0.25% of each employee’s total monthly wages, subject to a minimum of S$2 and a maximum of S$11.25 per employee per month, per the CPF Board SDL page. Only the first S$4,500 of monthly wages is levied. The rate has been 0.25% since 1 October 2008.
The maximum is simply 0.25% × the S$4,500 wage ceiling, which equals S$11.25, confirmed by the CPF Board’s SDL calculation guide.
Who needs to pay SDL in Singapore?
Every employer in Singapore pays SDL: companies, sole proprietors, partnerships, and non-profits, for every employee rendering services in Singapore. Coverage spans full-time, part-time, casual, temporary, and probationary staff, local or foreign, per the CPF Board. Employment Pass (EP), S Pass, and Work Permit holders are all included. There is no “S$500 threshold” below which nothing is owed.
Employers whose headcount is entirely foreign, and who therefore make no CPF contributions, still owe SDL. See the payment section for how they pay.
How do you calculate SDL?
Apply 0.25% to each employee’s total monthly wages, apply the S$2 floor and S$11.25 cap per employee, then sum across headcount and round the total down to the nearest dollar, per the CPF Board calculation guide. Total wages include basic salary, overtime, commissions, bonuses, allowances, and leave pay.
SDL uses its own S$4,500 monthly wage ceiling, which is separate from the CPF Ordinary Wage ceiling. Confusing the two is the most common calculation error. For how the CPF ceiling works, see our guide to CPF contributions for companies in Singapore.
Does SDL apply to part-time employees?
Yes. Part-time, casual, and temporary staff are all covered, and the S$2 minimum usually applies, per the CPF Board SDL page. A part-timer earning S$400 a month generates S$1 at 0.25%, so the employer pays the S$2 floor. There is no part-time reduction and no wage threshold that removes the liability.
Who is exempt from SDL?
Exemptions are narrow and cover people who are not employees rendering business services in Singapore. The SDL FAQ exempts domestic servants, chauffeurs, and gardeners employed wholly outside an employer’s trade or business, and employees rendering no services in Singapore for a full month.
Sole proprietors and partners owe no SDL on their own drawings; they pay only on wages paid to employees, per the CPF exemption guidance. Matriculated students on institution-approved internships are also exempt. Foreign employees are not exempt.
Do employers need to register for SDL?
No separate SDL registration is required for CPF-contributing employers, because SDL runs through the same CPF account and is billed alongside CPF contributions, per the CPF Board. Employers with only foreign employees make no CPF contributions but still owe SDL, and must arrange payment through the SWDA/CPF SDL channel.
When is the SDL filing deadline?
SDL is due within 14 days after the end of the wage month, so March wages are due by 14 April, per the CPF Board. If the 14th falls on a weekend or public holiday, payment is due the next working day. This aligns with CPF contribution timelines, which is why the two are usually paid together.
How do you pay SDL online in Singapore?
Most employers pay SDL bundled with CPF contributions through CPF EZPay, where the levy is auto-computed, per the CPF Board. Employers with no CPF contributions pay through the dedicated SDL channel. The old SingPost counter route is retired.
What happens if you don’t pay SDL on time?
Late or unpaid SDL attracts a penalty of 10% per annum on the outstanding amount, imposed under the Skills Development Levy Act 1979. The levy is legally enforceable, and CPF Board can pursue recovery.
SDL sits within a wider payroll obligation set. See our overview of statutory compliance in Singapore.
How do you correct an SDL underpayment?
Pay the shortfall for the affected months promptly through the CPF/SWDA channel and settle the 10% per annum late-payment penalty, per the CPF Board. Recompute each affected month separately rather than lumping the arrears into the current month, and keep the reconciliation records. Contact CPF Board for adjustments if amounts have already been submitted.
What are common SDL calculation mistakes?
The costliest mistakes come from wrong assumptions about who is covered and what counts as wages, per the CPF Board. Getting the mechanics right avoids penalties and overpayment.
- Excluding foreign employees because they have no CPF; EP, S Pass, and Work Permit holders are covered.
- Assuming a S$500 threshold removes the liability; no such threshold exists.
- Forgetting the S$2 minimum for low-wage and part-time staff.
- Applying the CPF Ordinary Wage ceiling instead of SDL’s own S$4,500 cap.
- Omitting bonuses, commissions, overtime, and allowances from the wage base.
- Not updating payroll after raises, new hires, or leavers mid-month.
What records do employers need to keep for SDL?
Keep wage and SDL payment records to support audit and reconciliation, per the SDL FAQ. Retain them for at least five years, in line with general Inland Revenue Authority of Singapore (IRAS) record-keeping practice. Records should let you recompute each employee’s levy, prove the amounts paid, and reconcile against CPF EZPay statements if CPF Board queries a filing.
What does the Skills Development Fund pay for?
SDL flows into the Skills Development Fund (SDF), administered by SWDA, which subsidizes employee training, grants, and SkillsFuture programs, per the SDL Act 1979. Employers who pay SDL can tap SDF course subsidies to upskill staff in areas such as digital transformation, leadership, and industry-specific skills. The levy funds the training system that employers themselves draw from.
