Form W-4 on MacBook

The IRS Form W-4 is required to be filled out every time there are changes in the amount of tax withheld from your paycheck. This form helps your employer calculate the correct amount of federal tax to be withheld from your pay. For example, when you are hired, your family situation changes, or you take out a loan with tax deductible interest, the math is different. Based on the information you provide via this form, your employer will calculate the take-home amount for your paycheck.

It is very likely that you will have to fill out the W-4 form multiple times when switching jobs or making tax withholding adjustments. So, it's better to fill it out once and store for repeated future use. You can add information to this form on any iPhone, iPad or Mac using the advanced productivity tool PDF Expert, the best PDF app to fill out tax forms.


How to fill Form W-4 on Mac

Follow these simple 6 steps to fill out Form W-4:

  1. Download the form W-4 from here;
  2. Install the free trial of PDF Expert;
  3. Start by referring to the Personal Allowance Worksheet to calculate the number of deductions you can claim.
  4. Proceed to fill out your information and numbers in the Deductions, Adjustments, and Additional Income Worksheet.
  5. Double check everything and save the form.
  6. Print out the form, separate the Worksheets, sign the W-4 form itself and hand it over to your employer.

Common mistakes to avoid while filling out Form W-4

- Misspelling your name or SSN in the W-4 form will most likely result in your employer rejecting it; so make sure the information is entered correctly.

- Proper calculation of the number of deductions is extremely important to avoid surprises during the tax season as you may end up owing money to the IRS. On the other hand, if you overreport your deductions, you will end up with a smaller take-home amount in your paycheck, but a larger tax refund at the end of the year which is like giving the IRS a free loan.

- Make sure you select the correct marital status box as it will also affect the amount of tax withheld from your paycheck.

You should keep all the forms in one place for easy organization, for example in PDF Expert on your iPad or iPhone. This enables you to quickly access the forms whenever you need them.

Once again, make sure you provide accurate information on your W-4. If you are unsure of some items, always consult with your financial adviser.
