What Are Custom Deductions?

Custom deductions are specific amounts withheld from an employee's paycheck beyond standard mandatory deductions such as federal and state taxes, Social Security, and Medicare. These deductions can include health insurance premiums, retirement contributions, and other voluntary or mandatory withholdings agreed upon by the employer and employee.

Mandatory Deductions

In addition to custom deductions, employers must also manage several mandatory deductions. These include:

1. Federal Income Tax

The amount withheld is based on the employee's W-4 form and federal tax tables. Clearly itemize this deduction on paystubs.

2. State Income Tax

Withheld based on state-specific tax rates and the employee's state tax form. Ensure state taxes are accurately reflected on paystubs.

3. Social Security Tax

Both employer and employee contribute to Social Security. The current rate for employees is 6.2% up to the wage base limit. This should be clearly itemized on paystubs.

4. Medicare Tax

Both employer and employee contribute to Medicare. The current rate is 1.45% on all earnings. This should be clearly itemized on paystubs.

5. Federal Unemployment Tax Act (FUTA)

Employers pay FUTA tax to fund unemployment benefits. While not deducted from employees' wages, it should be indicated on paystubs for informational purposes.

6. State Unemployment Tax Act (SUTA)

State-specific unemployment taxes paid by employers. Similar to FUTA, this is not deducted from employees' wages but should be indicated on paystubs for informational purposes.

7. Other Local Taxes

In some jurisdictions, additional local taxes may apply, such as city or county taxes. Ensure these deductions are clearly itemized on paystubs.

Types of Custom Deductions

Custom deductions include various withholdings from paychecks for benefits, legal obligations, and voluntary contributions, such as health insurance, retirement contributions, life and disability insurance, FSAs and HSAs, garnishments, loan repayments, union dues, charitable donations, and job-related costs for uniforms and tools.

Health Insurance Premiums

Regular premiums for company-sponsored health insurance plans can be deducted from employees' paychecks. Ensure compliance with ACA requirements and provide clear enrollment information to employees.

Retirement Plan Contributions

Employee contributions to retirement plans like 401(k) or 403(b) can be deducted pre-tax or post-tax. Offering matching contributions can enhance your benefits package and help employees save for retirement.

Life and Disability Insurance

Premiums for optional life or disability insurance plans can be deducted. It is important to clearly explain the benefits and costs to employees to ensure they understand their options.

Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA)

Pre-tax contributions for medical expenses or dependent care can be deducted for FSAs or HSAs. Ensure compliance with IRS regulations and provide guidelines on how employees can use these accounts.

Garnishments and Child Support

Court-ordered deductions for child support or debt repayment are mandatory. Employers must strictly adhere to legal requirements and prioriti

Loan Repayments

Deductions for the repayment of company-provided loans should be managed with clear agreements and proper documentation. Ensure employees are fully aware of the repayment terms.

Union Dues

Regular dues for union membership can be deducted according to union agreements. Employers should notify employees of any changes in union dues and ensure accurate deductions.

Charitable Contributions

Voluntary deductions for charitable donations can be set up. Provide information on supported charities and the potential tax benefits for employees.

Uniforms and Tools

Costs for uniforms, tools, or equipment required for the job may be deducted if previously agreed upon. Ensure that such deductions are reasonable and clearly communicated.

Setting Up Custom Deductions

Setting up custom deductions involves developing clear policies, obtaining employee consent, ensuring legal compliance, and conducting regular audits. This process helps employees understand and trust their paycheck deductions.

Policy Development

Establish comprehensive policies outlining the types of deductions offered, eligibility criteria, and procedures for initiating or terminating deductions. Clear policies help prevent misunderstandings and ensure consistency.

Employee Consent

Obtain written consent for all voluntary deductions. Transparency is key, so make sure employees understand the amount, frequency, and purpose of each deduction.

Legal Compliance

Ensure all deductions comply with federal, state, and local laws. Stay informed about limits and requirements for mandatory deductions like

Regular Audits

Conduct regular audits of payroll records to ensure deductions are correctly applied and compliant with relevant laws and agreements. Audits help identify and correct any errors promptly.

Communication with Employees

Communication with employees regarding paycheck deductions involves transparency in providing detailed information about deductions, ensuring clear reflection of deductions on pay stubs, and offering support services such as helpdesk and financial counseling. This ensures employees understand and trust their paycheck deductions, fostering satisfaction and confidence in the process.

  • Transparency: Provide detailed information about deductions, including how they are calculated and their impact on net pay. Clear communication helps build trust and ensures employees understand their paycheck deductions.
  • Pay Stub Information: Ensure paystubs reflect all deductions clearly, providing a detailed breakdown for employees. This transparency helps employees keep track of their contributions and withholdings.
  • Employee Support: Offer resources such as helpdesk services and financial counseling to assist employees in understanding their deductions. Supporting employees with their financial queries can improve their satisfaction and trust in the paystub process.

Additional Considerations

Additional considerations include allowing employees to opt out of voluntary deductions, prioritizing deductions to ensure legal compliance, addressing insufficient paychecks by following legal guidelines, and obtaining employee consent for adjustments. These measures help maintain fairness and legality in the deduction process.

  • Opting Out of Deductions: Employees can opt out of voluntary deductions like health insurance or retirement contributions, but cannot opt out of mandatory deductions such as taxes and court-ordered garnishments.
  • Prioritizing Deductions: Legally mandated deductions, like taxes and garnishments, take priority over voluntary deductions. Ensure that mandatory deductions are applied first, and manage voluntary deductions accordingly if there are limited wages.
  • Insufficient Paychecks: If an employee's paycheck is insufficient to cover all deductions, follow legal guidelines to prioritize mandatory deductions and potentially delay or reduce voluntary deductions with the employee's consent.


Effective management of custom deductions is essential for compliance and employee satisfaction. By understanding the types of deductions, setting up clear procedures, and maintaining transparent communication with employees, employers can ensure accurate and detailed paystubs.
