Hello @msgier11
Since your husband is claiming $2,000 in box 3 - that might be an indication why he has less taken our of his checks.
To ensure your tax withheld is appropriate for your tax situation, you can divide the amount you usually pay in federal taxes by the number of paychecks you receive in a year and compare it to the withholding from your and your spouses paystubs to find out if your estimates are accurate. You can always made an adjustment in box 4c for extra withholding to avoid balance due at the end of the year.
You and your spouse can update your W-4 form anytime during the year. Just remember, adjustments made later in the year will have less impact on your taxes for that year.
Hope this helps!
