\"w-4<\/p>\n

The W-4 explained…Top questions to consider<\/h2>\n

Here are some common W-4 questions explained…<\/p>\n

\u201cWhat if I start a new job?\u201d<\/h3>\n

As mentioned above, when you start a job, it’s important to revisit your Form W-4<\/a>.<\/u> It doesn’t change the amount of your pay that will go toward Social Security and Medicare. Those are defined amounts.<\/p>\n

If you don’t fill out a new W-4, you employer will definitely still give you a paycheck. But they’ll also withhold income taxes at the highest rate for single filers, with no other adjustments.<\/p>\n

\u201cHow is the amount withheld determined?\u201d<\/h3>\n

The W-4 is used by your employer to determine how much income tax to withhold based on your marital status and any other adjustments you decide to include on the form.<\/p>\n

\u201cWhat are withholding adjustments?\u201d<\/h3>\n

The new W-4 that came out in 2020 removed withholding allowances<\/a>. In fact, concepts and questions such as dependency allowances, number of exemptions and \u201chow many exemptions should I claim?\u201d have all gone by the wayside.<\/p>\n

The good news is that there are still ways to adjust your tax withholding on your tax return even if withholding allowances and claiming exemptions as a concept no longer exist. In fact, there are resources to help you answer any lingering questions before filling out your W-4 form. One particular resource worth trying is the W-4 paycheck tax calculator<\/a>. Just plug in your information, and it will help figure out which withholdings work best for you.<\/p>\n

\u201cCan I claim 0 allowances to get a Bigger Tax Refund? How can I do this on the new W-4?\u201d<\/h3>\n

On the new W-4, the nearest equivalent of claiming zero allowances this: filling out your w-4<\/a> and completing Steps 1 and 5 on the form and nothing else. These steps are simply the personal information section and signing the form at the bottom. This will allow your employer to withhold based on your filing status, the tax rates, and no other adjustments.<\/p>\n

One caveat: make sure to have enough withheld. If you don’t withhold enough taxes<\/a>, you may have a larger federal tax bill\u00a0once you file your return.<\/p>\n

\u201cShould I re-check my W-4 after I get married?\u201d<\/h3>\n

It’s best to revise your Form W-4 after major life events such as getting a new job, getting married, or having your number of dependents change \u2013 like when a baby is born or adopted or when your adult child is no longer considered a dependent.<\/p>\n

\u201cShould I declare myself exempt from withholding?\u201d<\/h3>\n

No, it\u2019s not a good idea to claim you\u2019re exempt simply in order to get a bigger paycheck. By certifying you are exempt, your employer wouldn’t withhold any federal income tax amounts during the year, and that would result in a large tax bill due in April. In addition to having to pay a whole year\u2019s worth of taxes, you could also face interest, underpayment penalties<\/a>, and other consequences.<\/p>\n
