This article explains what post-tax deductions are, which types are supported in Salaris, and how they are applied during payroll.

What Are Post-Tax Deductions?

Post-tax deductions are amounts withheld from an employee’s paycheck after payroll taxes have been calculated. These deductions reduce an employee’s net pay, but they do not reduce taxable income.

Post-tax deductions in Salaris fall into two categories:

Court-mandated, such as child support orders and other wage garnishments
Voluntary, such as union dues, loan repayments, or one-time employee-authorized deductions

Common Examples of Post-Tax Deductions

Deduction Type	Use Case
Child Support	Court-ordered wage withholding to support a dependent
Cash Advance Repayment*	Repayment for a company-issued loan or advance
Union Dues	Regular membership contributions to a labor union
Charitable Donation	Employee-authorized contribution to a nonprofit organization
Uniform or Equipment Fee	Reimbursement for issued materials or clothing
Event Fee	One-time deduction for company events or internal programs
Court-Ordered Garnishment	Deductions for tax liens, student loans, bankruptcies, or other legal debts

What is a Garnishment?

A garnishment is a legally required deduction from an employee’s wages, typically issued by a government agency or court. Garnishments are used to repay debts like child support, unpaid taxes, student loans, or court judgments.

Salaris currently supports child support garnishments, which can be configured and optionally remitted through the platform.
Other types of garnishments (e.g., tax liens or bankruptcy orders) are added as miscellaneous deductions and must be tracked and remitted by the employer.

How to Add or Manage Post-Tax Deductions

To add or manage a post-tax deduction in Salaris, go to Employees, select the employee’s name, and click the Deductions tab. From there, you can add new deductions or make changes to existing ones.

Category	Type	Description
Child Support Deductions	Court-ordered garnishments	May be automatically remitted through Salaris, depending on configuration.
Miscellaneous Deductions	Voluntary or employer-required	Includes repayments, dues, donations, and other non-court deductions.
Miscellaneous Garnishment Deductions	Court-ordered garnishments (non-child support)	Must be tracked and remitted manually by the employer.

📌Notes:

Salaris may remit child support deductions directly to the agency if configured to do so.
All other deductions, including court-ordered garnishments outside child support, must be remitted by the employer.

How to Add a Post-Tax Deduction

Go to Employees, then select the employee’s name.
Click the Deductions tab.
Click Add deduction under either Miscellaneous, Miscellaneous Garnishment, or Child Support, depending on the type of deduction you want to create.
Fill out the form, then click Save. The deduction will apply to all payrolls within the selected date range. The "End Date" field must exceed the next Pay Day for the deductions to show up immediately.

Section	Fields
Miscellaneous Deductions	Description, Total Amount, Amount or Percent, Annual Limit, Start Date, End Date
Child Support Deductions	Description, Amount, Max Percent, Agency, External ID, Issue Date, Effective Start, Effective End, Managed (Payment remitted toggle)
Miscellaneous Garnishment Deductions	Description, Total Amount, Amount or Percent, Annual Limit, Priority, Max Percent, Start Date, End Date

What Happens if the Employee Does Not Have Enough Net Pay?

A post-tax deduction cannot reduce an employee’s net pay below $0. If the employee does not have enough net pay after taxes to cover the full deduction, only the available amount will be deducted.

For example, if an employee has a $200 deduction but only $150.00 in available net pay, only $150.00 will be deducted from that payroll.

The system will attempt to collect the remaining balance from subsequent payrolls while the deduction remains within its effective date range. If the deduction expires before the remaining balance can be collected, the outstanding amount will not be deducted automatically.

If the full amount still needs to be collected, extend the deduction’s End Date to include a future payroll in which the employee is expected to have sufficient net pay.

Setting Up a Long-Term or Ongoing Deduction

If a deduction needs to continue over a longer period or across multiple payrolls, you can configure an Annual Limit and extend the deduction’s Start Date and End Date to cover the desired period.

When setting up the deduction:

Set the Annual Limit to the maximum amount that should be deducted during the year.
Adjust the Total Amount to reflect the full amount you intend to collect over the entire deduction period.
Set the Start Date and End Date to cover the full period during which the deduction should remain active.

This allows the deduction to remain active across multiple payrolls until the applicable limit or total amount is reached, provided the deduction remains within its configured date range.

How to Manage an Existing Deduction

Go to Employees > select the employee’s name.
Click the Deductions tab.
Locate the deduction under either Miscellaneous or Child Support.
Click Manage deductions.
- Select Edit and update any fields as needed.
- Select Remove to remove a deduction.
  Selecting Remove immediately deletes the deduction without a confirmation prompt. If removed by mistake, you’ll need to re-add the deduction.
Click Save to apply your changes.
