What Is the Skills Development Levy (SDL) in Singapore?
Key Takeaways
- ✓SDL is a compulsory levy under the Skills Development Levy Act (Cap 306), payable by every employer in Singapore for each employee, including part-timers, temporary staff, and foreign workers.
- ✓The rate is 0.25% of the employee's total monthly remuneration, capped at the first SGD 4,500 of wages, resulting in a maximum of SGD 11.25 per employee per month.
- ✓A minimum SDL of SGD 2 per month applies per employee, even when 0.25% of wages would calculate to less than SGD 2.
- ✓SDL funds go into the Skills Development Fund (SDF), which finances SkillsFuture programs, training subsidies, and workforce upgrading initiatives across all industries.
- ✓Employers pay SDL through the same monthly CPF submission process, making it part of the routine payroll cycle rather than a separate filing.
The Skills Development Levy is a payroll tax that every Singapore employer pays monthly for each worker on their payroll. It doesn't matter whether the employee is local or foreign, full-time or part-time, permanent or contract. If you pay them wages, you owe SDL. The money goes into Singapore's Skills Development Fund. This fund has been a cornerstone of the country's workforce development strategy since 1979. It finances training subsidies, course fee grants, and the SkillsFuture initiative that gives every Singaporean access to skills upgrading throughout their career. For employers, SDL is one of the smallest payroll costs, but it's one of the most strictly enforced. The levy is collected through the Central Provident Fund (CPF) Board alongside regular CPF contributions. You can't pay CPF without paying SDL. They're processed together in a single submission, due by the 14th of each month for the preceding month's wages.
SDL Levy Rates and Calculation
The SDL calculation is straightforward, but the minimum floor catches employers who don't realize it applies to very low-wage workers.
What counts as remuneration for SDL
Total monthly remuneration for SDL purposes includes basic wages, overtime pay, allowances, commissions, bonuses, and any other payments made to the employee for services rendered. This is broader than the CPF definition of ordinary wages. Variable components like one-off bonuses are included in the month they're paid. Housing and transport allowances count. Even payments in kind (meal vouchers, for example) can be included if they form part of the contractual remuneration. Directors' fees are excluded if the director doesn't have a contract of service. Independent contractors don't attract SDL because they aren't employees. Payroll teams should verify that their total remuneration calculation for SDL matches the definition under the Skills Development Levy Act, not just the CPF Ordinary Wages ceiling.
| Monthly Remuneration | SDL Amount | Calculation |
|---|---|---|
| Below SGD 800 | SGD 2.00 (minimum) | Minimum floor applies regardless of actual wage |
| SGD 800 | SGD 2.00 | 0.25% x SGD 800 = SGD 2.00 (equals minimum) |
| SGD 1,500 | SGD 3.75 | 0.25% x SGD 1,500 |
| SGD 3,000 | SGD 7.50 | 0.25% x SGD 3,000 |
| SGD 4,500 or above | SGD 11.25 (maximum) | 0.25% x SGD 4,500 cap |
| SGD 8,000 | SGD 11.25 (maximum) | Capped at first SGD 4,500 of wages |
| SGD 15,000 | SGD 11.25 (maximum) | Same cap applies regardless of how high the salary is |
Employer Filing and Payment Obligations
SDL isn't filed separately from CPF. The two are bundled into a single monthly submission, but employers need to understand the specific rules that apply to SDL.
Monthly submission process
Employers submit SDL as part of their CPF contributions through the CPF Board's online portal (CPF EZPay) or via approved payroll software with direct submission capability. The deadline is the 14th of the month following the wage month. For January wages, SDL is due by February 14. Late payments attract a penalty of 10% on the outstanding SDL amount, compounded monthly. There's no grace period. The CPF Board issues an auto-generated penalty notice, and repeated late payments can trigger audits. New employers must register with the CPF Board before their first submission. SDL obligations start from the first day you hire an employee, not from a registration date.
Who must pay SDL
Every employer in Singapore. This includes sole proprietorships, partnerships, limited liability partnerships, private limited companies, public companies, government bodies, statutory boards, and foreign companies with a local branch. There is no exemption based on company size, industry, or profitability. A startup with one employee and a multinational with 10,000 employees both pay SDL at the same rate. Non-profit organizations and charities are also required to pay SDL for their employees. Household employers paying domestic helpers aren't required to pay SDL, as domestic helpers aren't covered under the Employment Act for this purpose.
Record-keeping requirements
Employers must maintain payroll records showing the SDL calculation for each employee for at least 2 years. The CPF Board can request these records during audits. Digital records are acceptable. Your HRIS or payroll system should track the SDL amount per employee per month as a separate line item, even though it's submitted together with CPF.
Penalties for Non-Compliance
The Skills Development Levy Act gives the CPF Board and SkillsFuture Singapore strong enforcement tools. Non-compliance carries escalating consequences.
Late payment penalties
A 10% penalty is imposed on any SDL amount not paid by the 14th of the due month. This penalty compounds if payment continues to be late. Interest charges may also apply on prolonged arrears. The CPF Board issues automated penalty notices, and the amounts are added to the next month's statement. Employers who dispute a penalty must appeal to the SkillsFuture Singapore Agency within 14 days of the notice.
Prosecution and fines
Under Section 11 of the Skills Development Levy Act, employers who fail to pay SDL can face prosecution. The maximum fine upon conviction is SGD 10,000, with imprisonment of up to 6 months for severe or repeat offences. Directors of companies that default on SDL can be held personally liable. In practice, prosecution is reserved for persistent defaulters. The CPF Board typically works with employers through reminder notices and penalty charges before referring cases for legal action.
How SDL Funds Are Used: Training Grants and Subsidies
The Skills Development Fund, fed by SDL collections, distributes money back to employers and workers through several programs. Understanding these programs helps employers recoup their SDL expenditure through training subsidies.
SkillsFuture Enterprise Credit (SFEC)
Eligible employers receive a one-off SGD 10,000 credit to cover up to 90% of out-of-pocket costs for supported programs in job redesign, skills training, and workforce transformation. This credit comes from the same pool funded partly by SDL. Employers can use SFEC for courses, certifications, and transformation consultancy.
Absentee Payroll funding
When employees attend approved training during work hours, employers can claim Absentee Payroll (AP) funding at 80% of hourly basic salary, capped at SGD 7.50 per hour per trainee. This reimburses the employer for the productive time lost while the employee is training. For SMEs, the cap is higher. AP funding is especially valuable for companies that send large numbers of staff for SkillsFuture-approved courses.
Course fee subsidies
Singapore citizens and permanent residents can access subsidies of 50% to 90% of course fees for SkillsFuture-approved programs. These subsidies aren't paid directly from SDL, but the fund supports the broader SkillsFuture ecosystem that makes them possible. Employers benefit because their staff can be trained at a fraction of the market cost.
Setting Up SDL in Your Payroll System
Most modern payroll software used in Singapore calculates SDL automatically. Here's how to verify the configuration is correct.
- Confirm the SDL rate is set to 0.25% of total monthly remuneration, not ordinary wages (the CPF and SDL wage definitions differ).
- Verify the minimum SDL floor of SGD 2 per employee per month is applied. Some payroll systems calculate 0.25% without checking against the minimum.
- Ensure the wage cap of SGD 4,500 per month is applied so that SDL doesn't exceed SGD 11.25 per employee per month.
- Check that SDL is calculated on all remuneration components: basic salary, overtime, allowances, commissions, and bonuses in the month they're paid.
- Include part-time, contract, and foreign workers in SDL calculations. A common error is excluding them because they aren't on the standard payroll run.
- Reconcile SDL totals monthly against the CPF submission file before submitting. Discrepancies between payroll records and CPF submissions trigger audit flags.
- Set up SDL as a separate cost item in your GL (general ledger) so finance teams can track the total cost independently from CPF contributions.
SDL vs CPF Contributions: Key Differences
Employers often conflate SDL and CPF because they're submitted together. But they serve different purposes and follow different rules.
| Feature | Skills Development Levy (SDL) | Central Provident Fund (CPF) |
|---|---|---|
| Purpose | Fund national workforce training programs | Retirement, healthcare, and housing savings for employees |
| Who pays | Employer only | Both employer and employee |
| Rate | 0.25% of total remuneration (capped at SGD 4,500) | Up to 17% employer + 20% employee (varies by age and wages) |
| Wage definition | Total monthly remuneration | Ordinary Wages (capped at SGD 6,800/month) + Additional Wages |
| Minimum amount | SGD 2 per employee per month | No minimum (rate-based calculation) |
| Applies to foreign workers | Yes | No (foreign workers are exempt from CPF) |
| Employee sees deduction | No (employer cost only) | Yes (employee's share deducted from salary) |
| Filing deadline | 14th of following month (same submission) | 14th of following month (same submission) |
Common SDL Mistakes Employers Make
Despite SDL being a simple calculation, several recurring mistakes cause compliance issues.
Excluding foreign workers
Unlike CPF, SDL applies to all employees regardless of nationality. Foreign workers on work permits, S Passes, and Employment Passes all attract SDL. This trips up employers who assume foreign worker payroll obligations mirror the CPF exemption. Every foreign worker costs at least SGD 2 per month in SDL, on top of the Foreign Worker Levy.
Ignoring the minimum floor
Part-time workers earning less than SGD 800 per month still cost SGD 2 in SDL. For businesses with many low-wage part-timers (retail, F&B, cleaning), this adds up. A company with 200 part-time workers each earning SGD 400 owes SGD 400 in SDL per month, not SGD 200 (which would be the pure percentage calculation).
Using the wrong remuneration base
SDL remuneration is broader than CPF Ordinary Wages. One-off bonuses, commissions, and allowances all count for SDL in the month paid. Payroll teams that use the CPF OW figure for SDL calculation will understate the levy for months when bonuses or commissions are paid.
