After-Tax Deductions

After-tax deductions refer to the amounts subtracted from an employee’s pay after all mandatory contributions and taxes have been withheld. These deductions can vary by country and are typically used for various voluntary benefits or contributions.

What is an After-Tax Deduction?

After-tax deductions are taken from an employee’s income, often from their disposable earnings, the amount remaining after mandatory taxes and other required contributions have been subtracted. These deductions are used for various benefits or contributions that the employee has elected to pay for.

Pre-Tax vs Post-Tax Deductions

Pre-tax deductions are taken from an employee’s gross pay before taxes are applied, reducing the taxable income and, consequently, the taxes owed. 

Examples include health insurance premiums and retirement contributions. In contrast, post-tax deductions are taken after taxes have been applied to the gross income, meaning they do not reduce taxable income but are used for other benefits or savings plans chosen by the employee.

Post-Tax Deductions Examples

After-tax deductions can differ widely depending on the country and the specific agreements between employers and employees. Here are some examples of post-tax deductions in the UK, Philippines, and Singapore:

In the UK

In the UK, the mandatory deductions include the income tax and national insurance. Deductions after these are considered after-tax deductions. These deductions may include:

  • Repayment of accidental overpayment of wages
  • Wage garnishments 
  • Payment for buying shares in business 
  • Accommodation 
  • Union fees 

It’s imperative that the deductions don’t reduce your employee’s wage to less than the national minimum, unless, of course, the deductions are mandated or put into an agreement. For more information, please refer to the Government guide.

In the Philippines

In the Philippines, there are 4 mandatory deductions: income tax, PhilHealth (health insurance), Pag-IBIG (housing and savings), and Social Security System (pension).After-tax deductions may include: 

  • Voluntary health insurance premiums besides PhilHealth
  • Personal loans repayment deductions
  • Voluntary savings plans or investments

Can Employees Opt Out of After Tax Deductions?

Employees generally have the option to opt out of certain after-tax deductions, particularly those related to voluntary benefits or services. However, opting out may require following specific procedures as outlined by the employer or the service provider. It’s essential for employees to understand the terms of these deductions and any potential impact on their benefits.

Best Practices for Employers Regarding After Tax Deductions

After-tax deductions are vital for managing employee payroll and ensuring compliance with local regulations. These deductions occur after income tax has been applied to an employee’s earnings, typically covering items such as retirement contributions, health insurance premiums, and union dues. Here are best practices for HR and employers, taking into account the situations in the UK, Philippines, and Singapore.

Understand Legal Requirements

Familiarise yourself with the regulations set by the relevant authorities in each country:

  • UK: HM Revenue and Customs (HMRC)
  • Philippines: Bureau of Internal Revenue (BIR)
  • Singapore: Central Provident Fund (CPF) Board and Inland Revenue Authority of Singapore (IRAS)

Ensure all after-tax deductions comply with these regulations. Staying updated on any changes in tax laws and guidelines is crucial to maintain compliance. 

Note that there may be additional regulations from other government agencies to keep posted with. For example, employers in the Philippines need to comply with the regulations set by PhilHealth, Pag-IBIG, and Social Security System. 

Communicate with Employees

Transparency is essential. Provide clear explanations of all deductions on paystubs and ensure employees understand the reasons for these deductions. Obtain written consent from employees for non-mandatory deductions to avoid disputes and foster trust.

Implement Flexible Benefits

Offer salary sacrifice schemes and other flexible benefits where employees can opt for additional benefits, such as extra pension contributions or health insurance, which can sometimes be managed post-tax. Ensure that these schemes are well-communicated and understood by employees.

Maintain Accurate Record-Keeping

Keep detailed records of all after-tax deductions for auditing purposes and to address any employee queries. Regularly review and update records to ensure they are accurate and compliant with current regulations.

Regular Audits

Conduct periodic audits to verify that deductions are correctly calculated and properly authorised. This helps identify and rectify any discrepancies promptly, ensuring ongoing compliance and accuracy.

Manage Employee Loans and Advances

For deductions related to employee loans or salary advances, ensure they are managed according to company policy and do not excessively reduce an employee’s take-home pay. Clearly communicate the terms and conditions of these deductions to employees.

Stay Updated and Train HR Personnel

Regularly update HR personnel on the latest regulations and best practices in after-tax deductions. Provide ongoing training to ensure they are knowledgeable and can effectively manage deductions in compliance with local laws.


Understanding after-tax deductions is crucial for both employers and employees to manage payroll effectively and ensure that all contributions and benefits are accurately accounted for. By following best practices and maintaining clear communication, employers can facilitate a smoother payroll process and help employees make informed decisions about their post-tax deductions.
