Worker deductions are amounts that are withheld from an employee’s pay by their employer. Some worker deductions, such as taxes, are required by law, while others, like contributions to a retirement plan or health insurance premiums, are voluntary withholdings.
How do worker deductions work?
Worker deductions are typically made on a pay period basis, such as weekly, biweekly, or monthly. When an employee is paid, their employer will subtract the required or voluntary deductions from their gross pay (their pay before any deductions are made). The resulting amount is the employee’s net pay.
Which worker deductions are required by law?
There are several deductions that may be required by law, depending on the country. These include:
- Income tax: an amount withheld based on the employee’s tax rate and the income earned. In the U.S, some states and localities have their own income tax, which may also be withheld from an employee’s pay.
- Health insurance contributions: some countries have mandatory health insurance systems, requiring employees and employers to cover the cost of a health insurance policy. Health insurance contributions generally pay for medical expenses not covered by government-funded programs.
- Pension contributions: many countries have national pension plans, which require employers and employees to fund the benefits paid to workers and their dependents when they retire.
- Social insurance contributions: several countries require employees and employers to fund government-administered programs that provide financial support to individuals and their families in the event of illness, injury, or unemployment.
What are pre-tax deductions?
In the US, some worker deductions are made from an employee’s pay before taxes are calculated. This means that the deduction amount is not subject to income tax, and the employee pays less in taxes overall.
Some common examples of pre-tax deductions include:
- Contributions to a 401(k) or other retirement savings plan
- Contributions to a health savings account (HSA)
- Contributions to a flexible spending account (FSA) for medical or dependent care expenses
- Premiums for employer-sponsored health insurance
Pre-tax deductions can be a good way for employees to save money on their taxes and reduce their overall tax burden. They can also be a good way for employers to offer their employees additional benefits while reducing their payroll payments costs.
What are post-tax deductions?
Post-tax deductions are taken from an employee’s paycheck in the U.S after taxes have already been withheld. Typical post-tax deductions include:
- Roth IRA and Roth 401(k) retirement contributions
- Disability insurance
- Life insurance
- Charitable contributions
- Garnishments
- Union dues
