Tax withholding refers to the percentage of your income that your employer takes out from your paychecks for federal and state taxes. Since the U.S. has a pay-as-you-go tax system, you’ll gradually pay your tax bill throughout the year instead of making one lump sum payment when you file taxes.
When you choose to have taxes withheld from your paycheck, it can greatly reduce the amount you owe cometax time. Knowing the ins and outs of withholding is important because the amount withheld directly relates to your refund.
How does tax withholding work?
A tax withholding is money deducted from your paycheck for income taxes. In addition to federal income tax, your paycheck may also have FICA taxes withheld, which include Social Security and Medicare taxes, as well as state and local income taxes depending on where you live and work. You have the opportunity to withhold income when starting a new job. Your employer will have you complete Form W-4, which tells them how much money to reserve from your paycheck for taxes. When tax season comes around, whatever your employer withheld counts toward your tax bill.
When you submit a W-4 to your employer, they will use the information to withhold the correct percentage of federal and state income from your paycheck. Recommended withholding amounts differ depending on criteria, such as:
- Filing status
- Job status – the number, type of jobs, and the income from those jobs
- Dependents and their care expenses
Who is exempt from tax withholding?
Generally, exemptions depend on where you live, or whether you qualify for specific federal withholding exemption. If you live in Alaska, Florida, Nevada, South Dakota, Tennessee, Washington, Texas, or Wyoming, you won’t have to complete a state W-4, since these states do not collect income taxes. But, if you meet the federal requirements to file taxes, you must set up federal withholding with your employer.
Most employees are required to have federal income tax, Social Security tax, and Medicare tax withheld from their wages. However, you may qualify for an exemption from federal income tax withholding if you both owed no federal income tax in the previous year and expect to owe no federal income tax for the current year. To claim this exemption, you must indicate your exempt status on Form W-4. Keep in mind that an exemption from federal income tax withholding does not exempt you from Social Security and Medicare taxes, which generally still apply to most employees. If you do not qualify for an exemption, your employer must withhold taxes from your paycheck based on the information you provide on your Form W-4.
Am I withholding enough money for taxes?
Finding the sweet spot is important when setting your tax withholding percentage and filing your tax return. Ideally, you should aim to withhold just enough to cover your tax liability, avoiding any unpleasant surprises during tax season.
While receiving a tax refund may seem like a windfall, it’s essentially an interest-free loan to the government. Striking the right balance between how much money you reserve for taxes and the amount you actually end up owing ensures you keep more of your hard-earned money throughout the year while still meeting your tax obligations.
Suppose you have a tax bill at the end of the year or receive an excessive refund each year. In that case, you may consider updating your W-4 so that your withholding percentage matches your tax liability.
Am I eligible for part-year withholding?
You are eligible for part-year tax withholding if you were employed for less than 245 days during the current calendar year.
If you work a summer job, seasonal job, holiday job, or have temporary work, you should consider the part-year method. Also, if you are starting a new job late in the calendar year, this will prevent over withholding fromyour paycheck.
Otherwise, your employer automatically calculates the amount of tax withheld from your paycheck based on a full year’s earnings.
For example, let’s assume you have a temporary job and get paid $15,000 for three months of work. The normal method assumes that you are earning $5,000 every month, or $60,000 a year ($5,000 x 12 = $60,000).
In reality, you are only earning $5,000 per month for three months. If your employer agrees to part-year tax withholding, they will report your total $15,000 as if it were earned over the entire year.
This equates to $1,250 per month ($15,000 / 12 = $1,250).
How can I estimate my tax liability?
Your tax liability is essentially the tax bill you owe to a federal, state, or local authority. The money reserved by way of tax withholding counts as payments made in anticipation of your estimated tax liability. Knowing your estimated tax liability is helpful information when completing your W-4 and setting the amount you will have withheld throughout the year.
One of the best ways to estimate your tax liability is to refer to the prior year. If your financial situation hasn’tchanged significantly, your previous year’s tax return can give you a baseline estimate for the current year. Your total tax liability can be found on line 24 of Form 1040. If you filed with TaxSlayer last year, reviewing your prior year’s return is as easy as logging into your account.
Calculating your federal withholding percentage offers another method for determining your tax liability and, ultimately, how much will be withheld from your paycheck. Continue reading to learn more about calculating your federal withholding percentage.
How to calculate and change your federal withholding percentage
Your tax withholding is based on the information you provide on Form W-4. Unlike previous versions of the form, the current W-4 no longer uses withholding allowances. You can estimate how much money will be withheld from your income using the IRS Withholding Calculator.
You can change your tax withholding percentage at any time by contacting your employer. But the IRS recommends adjusting your W-4 anytime your personal or financial situation changes. Below, you’ll find a few common reasons to modify your W-4:
- You’ve had a change in income
- You’ve recently expanded your family (marriage, birth of a child, adoption, etc.)
- You’ve recently started a small business
- You bought a new home
- You’re retiring
- You have increased itemized deductions, interest, dividends, or self-employed income
Is retirement income subject to withholding?
Yes, many types of retirement income are subject to federal income tax withholding. Once you retire, you may receive income from sources such as pensions, annuities, Social Security benefits, and withdrawals from retirement accounts like traditional IRAs and 401(k) plans. To set up or adjust withholding on retirement income, you may need to complete forms provided by the payer or plan administrator.
Form W-4P
You’ll complete Form W-4P if you receive pension, IRA, or annuity payments. If you forget to fill out this form, taxes from pensions will be withheld based on a single filing status with no adjustments.
Form W-4V
You will get Form W-4V if you receive unemployment compensation, Social Security benefits, or other types of payment from the government.
