Paycheck Taxes & Deductions Knowledge Center

Understand where your paycheck went before planning where it should go.

A salary or hourly rate is not the same as take-home pay. Paychecks may include federal tax withholding, Social Security tax, Medicare tax, state/local tax, health insurance, retirement contributions, garnishments, child support, and other deductions. Balance On Hand works best when users enter real take-home pay, not gross pay. Understanding paycheck deductions helps users budget from the money they actually receive.

Understanding Your Paycheck

The amount deposited into your bank account after each pay period is your net pay, not your gross pay. The difference is taxes and deductions. Understanding each line item helps you budget from real money, not theoretical income.

Federal Income Tax Withholding

Federal income tax is withheld from most paychecks based on your W-4 elections, filing status, and income level. This withholding is not your final tax bill. It is an estimate. At tax time, you may get a refund if too much was withheld or owe additional tax if too little was withheld.

Social Security and Medicare Taxes

FICA taxes fund Social Security and Medicare. These are mandatory payroll taxes that appear on every paystub. The employee share is a fixed percentage of wages. Understanding these deductions helps explain why net pay is noticeably lower than gross pay.

State and Local Taxes

Many states and some cities impose their own income taxes that are withheld from paychecks. Some states have no income tax. The rules vary by where you live and where you work, and both locations may matter.

Benefit and Retirement Deductions

Health insurance, dental, vision, life insurance, disability, HSA, FSA, and retirement contributions are commonly deducted from paychecks. Some are pre-tax, reducing taxable income. Understanding these deductions helps verify that your elections match what you intended during enrollment.

Garnishments and Support Orders

Court-ordered deductions including child support, wage garnishments, and tax levies reduce take-home pay further. These deductions take priority over voluntary deductions and cannot be stopped without a court order or agency action.

Budgeting from Net Pay

Balance On Hand works best when you enter the actual deposit amount, not your salary or gross pay. Every dollar deducted before your paycheck arrives is money you cannot spend on bills, food, rent, or savings. Planning from real take-home pay prevents budget gaps.

If you choose...
