Paycheck Calculator and Form W4

W-4 Form

This page covers managing and understanding your federal tax withholding per paycheck. Most refunds result from too much tax withholding, so you can keep more of your hard-earned money now by understanding this vital information.

The Form W-4 determines federal tax withholding. However, it does not reveal your paycheck's actual federal tax withholding amount. This makes it difficult for taxpayers to complete Form W-4 and the tax plan in preparation for their next tax return.

The eFile.com Paycheck Calculator or PAYucator answers these important W-4 tax planning questions: What will my tax withholding per paycheck or pay period be, and how can I increase or decrease my tax withholding per paycheck or pay period? As an added benefit, it will create the W-4 form for you along the way.

Below are step-by-step instructions on how to use the paycheck calculator while your W-4 is automatically completed for you. (The images below show the corresponding fields on the Form W-4). You will know the federal tax withholding amount based on your salary, filing status, etc., before you submit the form to your employer (not the IRS).

Tip: If you want to get your big tax picture for the tax year, use the free 2023 Tax Calculator and enter all your income, deductions, etc., and estimate your tax results. Use the PAYucator again to adjust your W-4 tax withholding based on these results. If this is too complicated, contact an eFile.com Taxpert® for free assistance.

Step by Step Instructions: Paycheck Calculator and Form W4

Sections A, B, C, D, and E are the entries on the Paycheck Calculator and how they correspond to Steps 1, 2, 3, 4, and 5 on the Form W4. Once you enter information on the Paycheck Calculator, the Form W-4 will be created by the app. You can email the form to your employer afterward or download the W-4 at the end of the paycheck calculator.

Start the Paycheck Calculator. Each question and section of the paycheck calculator links here for detailed instructions and suggestions by the corresponding calculator questions: A1, A2, B1, etc. At the end of the process, your personalized Form W-4 will be created in an easily downloadable or emailable format.

Paycheck Calculator, W-4
Descriptions, Explanations, Suggestions and Tips
Paycheck Calculator Question A1:
Select your Filing Status on the Paycheck Calculator as of December 31 of this year.

For question A1, the Paycheck Calculator asks you to select a tax return Filing Status: Single, Married, Surviving Spouse, or Head of Household. On your federal tax return, you are required to enter your Filing Status. It is mainly based on your marital status as of December 31 of the given tax year, and the tax withholding changes by filing status.

Tip: Since the W-4 is a planning tool, unlike a tax return, you may change your filing status to optimize your tax withholding. For example, you might be single in March of a given tax year but be married by December 31 of the tax year. Thus, you could select married as your status on your W4. Or, you might be married as you complete the W-4 form but are divorced by December 31. Thus, you might want to enter single or head of household. Below is Step 1-c, the section on the W-4 where the calculator will place your filing status.

Paycheck Calculator Question A2:
Do you (or you and your spouse if married) have more than one job?

If you have one W-2 job, select No. This includes your spouse if married, so the No would apply to households where only one member of a couple has a W-2 position. 

If you (or you and your spouse together if married) have two jobs, and if the lower-paying job's earnings are more than half of the pay at the higher-paying job, select Yes here. (Note: Do the same when you use the paycheck calculator to complete the W-4 for the second job.)

If the pay difference is less than half at the lower paying job than the pay at the higher paying job, then answer Yes and complete this worksheet and follow the instructions on the worksheet.

Married or not, if your household has more than two jobs, answer Yes, complete this worksheet, and follow the instructions on the worksheet.

W-4 Step 2
Paycheck Calculator Question B1:
Select your Pay Period for this Job

If you do not know already, ask your employer how often you will get paid. Here is a list of the most common pay periods and number of paychecks:
Semi-monthly: 24
Weekly: 52
Bi-weekly: 26 or 27 (based on calendar year)
Monthly: 12
Annual: (based on pay period). If you have your annual gross pay amount, divide that amount by the number of the expected pay periods. Select that pay period with the Paycheck Calculator here, and after the next question below, enter that amount under B3. Enter Gross $ Amount per pay period.

Form W-4 does not capture the pay period; thus, there is no image. The pay period is used to calculate your tax withholding amount
Paycheck Calculator Question B2:
Select your Payment Type

If you get paid a salary, enter that type here. If you receive multiple salaries for the same job, click the Add link. (Do not add salary income from another job here; create a separate paycheck with the PAYucator). If you also receive hourly-based pay for this job, multiply the hourly rate by the number of hours and add it as salary.

If you log your hours and get paid hourly, enter the hourly rate and number of hours per pay period. If you receive multiple hourly-based payments for the same job, click the Add link. Do not add hourly income from another job. If you also receive a salary for this job, divide the salary amount by the number of hours you work for this salary. For the Hourly Rate, enter the number of hours and the result of Salary/Hours = Hourly Rate here.

Form W-4 does not capture the payment type; thus, there is no image. The payment calculates your tax withholding per pay period and annual gross payment or income.
Paycheck Calculator Question B3:
Enter your gross $ Paycheck Amount per Month

This is the gross salary or hourly payment amount you get paid per selected pay period before taxes and other deductions are deducted.

You can determine your gross annual pay or income by multiplying this amount by the number of pay periods.

If you only have your annual pay or income, divide that amount or income by the number of pay periods you have selected with the PAYucator or Paycheck Calculator. You will then know your gross paycheck amount per pay period. Enter that amount here.

If you need to add additional income from this job, click the Add link and enter it here. (Note: Do not enter income from other jobs here). Form W-4 does not capture the gross paycheck or payment amount; thus, there is no image. The per pay period gross paycheck amount is used to calculate your federal tax withholding.

Paycheck Calculator Question C1:
Select a Pre-Tax Health Insurance Type and enter the amount

If you make contributions to one or more employer-offered pre-tax health insurance plans, select from one of the following medical plans: Medical, Dental, Vision, HSA 1 or Health Savings Account, FSA or Flexible Savings Account or Other, and enter your per-pay period medical plan contribution amount.

This amount will reduce your take-home pay, and you will not pay federal income taxes or make Social Security and Medicare contributions from your pre-tax health insurance plan payments.

If you need to add pre-tax medical health plan contributions for this job, click the Add link and enter them here. (Note: Do not enter contributions from other jobs here).

Form W-4 does not capture medical insurance contributions; thus, no image exists. The pre-tax medical health plan deductions are used to calculate your per-pay period federal tax withholding.
Paycheck Calculator Question C2:
Select a Pre-Tax or After-Tax Retirement Plan and enter the amount

If you make contributions to one or more employer-offered pre-tax or after-tax retirement plans, select from one of the following retirement plans: 401(k), 401(k) catch-up, Roth 401(k), Roth 401(k), 403(b), 403(b) catch-up, Roth 403(b), Roth 403(b) catch-up; generally, only the Roth plans are after-tax plans.

This retirement contribution amount will reduce your take-home pay amount. You will not pay federal income taxes (for pre-tax plans), and Social Security and Medicare contributions will be deducted. For after-tax plans, federal taxes will also be removed. Thus, the retirement plan contribution and associated taxes will reduce the take-home pay.

If you need to add additional retirement plan contributions for this job, click the Add link and enter them here. (Note: Do not enter contributions from other jobs here).

Form W-4 does not capture retirement plan contributions; thus, no image exists. Retirement contributions are used to calculate your per-pay period federal tax withholding.

Paycheck Calculator Question D1:
Enter the number of your Dependents or est. Child Tax Credit
Increase Dependents => Decrease Tax Withholding
Decrease Dependents => Increase Tax Withholding

If unsure who qualifies as your Dependent(s), use the DEPENDucator tool and enter the number here.

The PAYucator applies the maximum Child Tax Credit per pay period. However, you might not qualify for the total child tax credit amount if you have other income. Therefore, you can adjust the Dependent-based Child Tax Credit amount here. If you increase your child tax credit amount, your tax withholding per pay period would decrease. Decreasing the child tax credit amount would increase the per pay period tax withholding amount.

For accuracy purposes and to be comprehensive, we need to point out that if you use the paycheck calculator during the year, you can increase the child tax credit amount here to compensate for the past pay periods for the current year. For example, to claim a $2000 child tax credit for the entire year on your tax return, you would enter $333.33 as your child tax credit here for the monthly pay period if you completed the W-4 for July 1- December 31. If you completed the W-4 in any other month, divide $2000 by the remaining pay periods for the current year and enter that amount. If you do this, you must submit a new W-4 by January 1 next year to adjust this for the new tax year, and you would enter $166.66 in January next year. Contact a Taxpert if you have questions about this.

Paycheck Calculator Question D2:
Enter the number of Other Dependents or est. Other Child Tax Credit Amount
Increase Dependents => Decrease Tax Withholding
Decrease Dependents => Increase Tax Withholding

If you are not sure who qualifies as your Other Dependent(s), use the RELUcator tool as you can find out if one of your relatives might be eligible as your Other Dependent.

The PAYucator applies the maximum Other Dependent Credit by default for the given pay period.

You can adjust the Other Dependent Credit amount to increase your tax withholding by reducing or decreasing your tax withholding by increasing the credit amount.

Paycheck Calculator Question D4:

Paycheck Calculator Question D5:
Enter an Amount for additional Deductions
Increase Deductions => Decrease Tax Withholding
Decrease Deductions => Increase Tax Withholding

Do not enter Standard Deductions here as they are applied by the PAYucator or paycheck calculator. Enter any estimated tax return deductions here.

If you increase the tax deduction amount here, it will decrease your paycheck federal tax withholdings. If you decrease tax deduction, it will increase your W4-based federal tax withholding amount.

Tax deductions here and thus on the W-4 Form are a tool to increase or decrease per pay period federal tax withholding. Remember, as long as you keep your tax return results at a low refund, you can use tax deductions to manage your tax withholding amount.

Paycheck Calculator Question D6:
Enter an Amount for other Income
Increase income => Increase Tax Withholding
Decrease income => Decrease Tax Withholding

If you have other income in addition to the W-2 income from this job and you are not withholding federal taxes anywhere else, e.g., via Form 1040-ES, etc., for this income, and you wish to withhold federal income taxes via this job, enter this income amount here by the pay period selected.

If you only have the other income amount for the tax year, divide the other income amount by the remaining pay periods for the year. For example, if the other income was $2000 and it's August, and there are four remaining monthly periods left for the year, divide $2000 by four and enter $500. Contact a Taxpert if you have questions about this.
