Top Questions to Better Know About the W-4 Form
To better understand the W-4 Form, here are the top questions mentioned. So read on and gather all the information.
If I Claim 0 on My W-4 Form Will I Owe Taxes?
The amount of taxes is estimated by the total allowance number on line five that you claim. By mentioning "0" on line 5, you state that for each pay period, the maximum tax amount should be taken out. With the new system, you can show whether you need less or more than the standard amount. In case you have zero adjustments and dependents, from your paychecks, the standard tax amount will be withheld.
It means that, while on your paychecks you get less money, at the end of the year your tax bill will be lower. However, you still might owe taxes. For instance, you are self-employed and you do not have an account for those taxes you withhold more on your W-4 Form.
Can You Claim Tax Exemption from Tax Withholding on Your W-4?
Yes, you can claim tax exemption from tax withholding on your W-4 Form. It means that, on your income, your employer would not withhold any amount to pay federal income tax. However, you only qualify for this when you do not have any tax liability from the previous year. Additionally, in the current year also you do not expect any tax liability.
For instance, you are an individual taxpayer with $8000 approximate yearly income. In this scenario, you are not liable to pay federal income tax. It is because the standard tax deduction, which you claim on your return, would eliminate the possibility of owing any tax on your earnings.
Can the W-4 Form be used in Self-Employment Income?
Yes, you can use the W-4 Form in your self-employment income to know the taxes you owe in addition to your earnings from your primary job. Through your withholdings from your salary, to account for your self-employment taxes on Step 4(a) of the W-4 Form, mention this income. After that, in Step 4(c), you need to mention your self-employment tax each pay period.
However, know that the W-4 Form does not calculate your self-employment tax, so you need to do this on your own. While some individuals might opt for the W-4 Form partially for calculating self-employment taxes. In this, for estimating the quarterly taxes, the accurate method to use is 1040-ES.
If you expect to owe more than $1,000, then you generally need to pay the estimated taxes quarterly. Throughout the year, these taxes are distributed into four payments.
*Note: Remember that if you are opting for self-employment taxes with your W-4 withholdings, know that you still owe taxes. It is specifically when from your self-employment income you do not earn an amount during each pay period. Additionally, you need to use a calculation to know the owed tax amount.
When to Update Your W-4 Form?
You should update your W-4 Form when you experience a big change in your income. When you owe too much money from your paychecks. It states that without any interest, you have given a loan to the federal government. However, if you withhold a very low amount, then you may get an unexpected tax bill. Additionally, need to pay a penalty when you file your income tax return or for underpayment.
Furthermore, instead of facing this issue every year, it is better to update your W-4 Form. It will help you in two ways:
If you want to pay the tax amount you owe, it is a good option to avoid this result.
If every year you want to get a big tax refund, it is vital to know about your withholding amounts. It is because your tax refund is directly impacted by withholding.
