Payday can lift your spirits when your bank account is running low. However, as anyone in the workforce can tell you, take-home pay doesn’t usually equal gross pay. Instead, you share a chunk of your earnings with the federal and state governments.

Besides an array of taxes, you’ll also see deductions for medical insurance and retirement plan contributions. All of this probably leaves you wondering, “What will my paycheck be?” Understanding your paycheck after taxes can help you plan better, so you can live well on a budget.

Income Tax Withholding

If you work as an employee, your employer likely withholds money from your paycheck to pay your income taxes. The amount withheld includes not only federal income taxes, but also state and local income taxes, if they are applicable.

The information you supply when filling out Form W-4 determines how much your employer will withhold from each paycheck for taxes. The form tells your employer your filing status and how many allowances you are claiming. Each allowance reduces the amount of taxes withheld.

However, it can be a mistake to claim too many allowances. If you do, you won’t have enough withheld to meet your tax obligation. That could leave you writing a check to the government when you file a tax return. Worse, you might owe an extra $500 penalty for claiming too many allowances.

If you are an independent contractor, your employer won’t withhold money from your paycheck for taxes. Instead, you’re responsible to make estimated tax payments to the IRS at least quarterly to cover what you will owe at tax time. If you don’t make these required estimated payments, you might owe interest and penalties.

Social Security and Medicare Taxes

Your employer also withholds Social Security and Medicare taxes, known as FICA payroll taxes. Generally, 6.2% of your income is taken out for Social Security taxes and 1.45% is taken out for Medicare taxes.

But, if you’re a high earner, you might not pay Social Security taxes on your entire paycheck. The Social Security tax only applies to the amount of earned income equal to the Social Security wage base. Each year, the Social Security wage base adjusts, and in 2021 it’s $142,800. So, if you bring home $145,000, you won’t have to pay Social Security taxes on your last $2,200 of income.

Your employer also feels the pain of payroll taxes, as it must pay an equal amount on your behalf. For example, if your wages are $50,000 for the year, you’ll see $3,825 taken out of your paycheck; but your employer will also pay an additional $3,825 to the government in payroll taxes on your wages.
