You have a couple of items to consider when completing the W4. You have multiple jobs and pension income. Since you do not mention self-employment, Step 2(a) of the W4 does not apply to you. For your full-time income, you may use Step 2(b) or Step 2(c) for withholding calculations for your employer.
If you have one job each that pays relatively the same amount, you can check the box in Step 2(c) and submit the W4s to each employer.
If you and your spouse have multiple jobs or one job pays more than half of the other job, fill out the worksheet for Step 2(b) for only one of the W4s. Enter the results for that Step 2(b) worksheet on Line 4(c).
For either choice in Step 2, be sure to complete Step 3 for only one W4s you complete for your employer If you have dependents.
You can submit an Arizona Form A-4P to start withholdings from your husband’s pension income. The Form AZ-4P offers numerous choices for percentage of pension income to be withheld. Arizona has a flat tax rate of 2.5%, but you can opt to have a higher percentage withheld. You submit the Form AZ-4P to the payor of your pension or the administrator of the pension fund. Do not send the form to the Arizona Department of Revenue. You can access the From AZ-4P here: https://www.psprs.com/wp-content/uploads/2025/01/Arizona_Form_2025_A-4P.pdf
