How Do Employers Calculate Skills Development Levy in Singapore?

The Skills Development Levy (SDL) is one of the smallest figures on a Singapore payslip. To calculate SDL, employers apply 0.25% to each employee's total monthly wages, and the amount never exceeds $11.25 per employee.

In this guide, we explain how Singapore employers calculate the levy for 2026. We cover its purpose, coverage, calculation, payment deadline and common mistakes.

What Is the Skills Development Levy (SDL) in Singapore?

The SDL is a statutory payroll levy paid by Singapore employers on their employees' wages, with the proceeds funding national skills training.

The levy is imposed under the Skills Development Levy Act 1983 (SDLA) on every employer carrying on business in Singapore. The Skills and Workforce Development Agency (SWDA), formed through the merger of SkillsFuture Singapore and Workforce Singapore on 1 July 2026, administers it. CPF Board collects SDL with CPF contributions for employers making CPF contributions, while employers that hire only foreign employees pay SDL directly to SWDA.

Levy proceeds flow into the Skills Development Fund, which finances training support for the workforce. Employers who pay the SDL stay connected to the SkillsFuture movement: course fee funding, absentee payroll support and similar grants are available when companies organise structured training for staff in Singapore. Most of our payroll clients treat the levy as the price of admission to Singapore's publicly supported training system.

The SDL is borne entirely by the employer. SDL is payable by the employer and must not be deducted from an employee's salary. The amounts are modest — at most $11.25 per employee per month from 1 January 2026 — but the obligation applies in full however small the payroll.

Which Employees Are Covered by SDL?

SDL is generally payable for employees working in Singapore regardless of nationality, age, salary level or contract type, subject to statutory exemptions.

The levy attaches to the employment relationship, not to any category of worker. That single principle resolves most coverage questions that reach our payroll desk. The four groups below cover the situations Singapore employers ask about most.

1. Local and foreign employees

SDL applies to Singapore citizens, permanent residents and foreign employees on Employment Pass, S Pass or work permits alike. A common error is assuming that an employee exempt from CPF contributions is also exempt from SDL. The two regimes are not linked: Where an employer hires only foreign employees, it pays SDL directly to SWDA. With more foreign workers coming into Singapore easing manpower crunch pressures across labour-tight industries, this distinction now affects more employers every year.

2. Part-time, casual and temporary staff

Short engagements generally attract SDL. There is an exception. It applies where employment commences and ceases in the same month. The employee must not have been employed by that employer for aggregate periods exceeding 31 days. A part-time assistant earning $800 a month is covered, and the SDL payable is $2. Temporary, contract and probationary staff are equally covered, and there is no small-employer exemption.

3. Employees of any age and seniority

SDL has no age ceiling, unlike CPF contributions. Staff re-hired under seniority schemes, employees beyond the CPF contribution ages and any director drawing a salary as an employee of the company all attract the levy.

4. Self-employed persons and seafarers

Self-employed persons, partners who draw no employee wages and certain seafarers covered by separate rules sit outside the levy. There is a flip side worth noting: the moment a business incorporates and begins hiring, the SDL obligation starts from the first payroll run. Many owner-operators first encounter the levy when they convert a sole proprietorship into a private limited company and take on staff.

How Is SDL Computed Under the 2026 Parameters?

For each employee, SDL for the month is 0.25% of monthly total wages. Two limits apply:

• Minimum: $2 for an employee earning less than $800.
• Maximum: $11.25 for an employee earning more than $4,500.

Payroll teams need two details to calculate SDL correctly: the definition of wages and the parameters effective from 1 January 2026. The parameters followed the Budget 2025 announcements.

Wages for SDL purposes include all remuneration in money payable for the month. Basic salary, overtime pay, allowances, commissions, bonuses and annual wage supplements paid that month count. Employer CPF contributions do not count. They are paid on top of wages. SDL follows wages paid in the calendar month. A year-end bonus can therefore push that month's SDL to the cap.

For levy months in 2026, the rate is 0.25% of monthly total wages. The minimum is $2 for an employee earning less than $800 a month, while the maximum is $11.25 for an employee earning more than $4,500. Payroll systems using incorrect parameters can understate or overstate the levy.

Step 1: Add up the employee's total wages for the month

Take every wage element payable in money in that calendar month, including any bonus or commission paid in it. The $11.25 maximum applies where monthly total wages exceed $4,500.

Step 2: Apply the 0.25% levy rate

Multiply the month's total wages by 0.25%. At $3,200 of wages the provisional levy is $8.00; at $5,400 it is $13.50, before the cap is applied.

Step 3: Check the $2 minimum and the $11.25 cap

Where wages fall below $800, the 0.25% result drops under the $2 floor and the employer pays the $2 minimum. Where wages exceed $4,500, the levy is capped at $11.25 for the month. Both tests apply per employee, per calendar month.

Step 4: Total the levy across employees and pay by the 14th

For employers making CPF contributions, add the SDL for every employee to find the month's payable amount and submit it with CPF contributions by the following month's 14th. Employers that hire only foreign employees pay SDL directly to SWDA.

How and When Must SDL Be Paid?

SDL for any calendar month is due by the 14th of the following month. CPF Board collects SDL with CPF contributions for employers making CPF contributions, while employers that hire only foreign employees pay SDL directly to SWDA.

Employers making CPF contributions submit SDL through the CPF Board's digital services, and the levy is collected with monthly CPF contributions. SDL for October 2026 is due by 14 November 2026.

SDL remains due when an employer has no CPF-liable employees. For example, a company with only work-pass holders pays it directly to SWDA. Most clients automate the cycle through GIRO or payroll software. This reduces deadline risk.

1. The monthly deadline

The 14th of the month after the wage month is a statutory date, not a guideline. Payment must land by then; a transfer initiated on the 15th is late however quickly it is processed.

2. What happens when SDL is unpaid

Unpaid levy attracts a late-payment penalty on the amount outstanding, with further penalties as default continues. Under the Skills Development Levy Act 1983, non-payment and false statements about wages or headcount can also lead to court fines, and imprisonment in serious cases. We encourage clients to correct historical shortfalls before the CPF Board raises them.

3. The tax side of the levy

SDL paid on employees is a deductible business expense when computing chargeable income. Keep payroll records accurate so the levy flows into the tax computation.

Which Common SDL Mistakes Should Employers Avoid?

Most SDL shortfalls we see are procedural. They include:

• stale levy parameters
• SDL computed on basic salary instead of total wages
• whole categories of workers left out of the payroll

None of these errors is difficult to fix. Each one, however, quietly builds a shortfall month after month until correcting it costs more than getting it right would have.

1. Running payroll on pre-2026 parameters

Systems and spreadsheets with incorrect minimum or maximum settings misstate SDL for every affected employee. The first payroll run of each year is the natural checkpoint for the rates.

2. Calculating SDL on basic salary alone

Because the levy attaches to total wages, omitting overtime, allowances or commissions creates a persistent shortfall. The classic case falls in December, when bonuses and the annual wage supplement lift affected employees to the cap.

3. Passing the levy to the employee

SDL is the employer's statutory cost. Deducting it from wages breaches the SDLA even where the employee has consented, and the shortfall remains the employer's unpaid statutory liability.

4. Leaving workers outside the CPF cycle out

Foreign employees and staff beyond CPF ages are easy to drop when payroll logic is built around CPF tables, yet both attract SDL. A monthly reconciliation listing every wage-earner — CPF-liable or not — is the simplest safeguard.

Conclusion

Skills Development Levy compliance comes down to a short checklist. SDL is 0.25% of each employee's monthly total wages. A $2 monthly minimum applies for employees earning less than $800, while the maximum is $11.25 for employees earning more than $4,500. CPF Board collects SDL with CPF contributions for employers making CPF contributions, while employers that hire only foreign employees pay SDL directly to SWDA by the 14th of the following month. It covers local and foreign employees on a Singapore payroll and cannot be shifted to the employee.

Accuracy matters. Underpaid levy accrues penalties under the SDLA. Correctly paid levy is deductible against chargeable income.
