The important thing is to file with the correct status when you file your income tax return. If you are married and living with your spouse, then Married Filing Jointly (MFJ) is the choice that you would likely select when you actually file. HoH does not appear to apply to you since you appear to be living with your spouse. Note that the Standard Deduction for MFJ is $24,000 (assumes under age 65 and not blind). The Standard Deduction for HoH is $18,000. Therefore using a withholding table, which would assume an $18,000 deduction instead of the real $24,000 deduction, could result in too much money being withheld from your pay than you would need to have withheld. The effect of the over withholding would result in a higher refund. Getting a higher refund is not a legal problem, but it might not make the most financial sense. Unless you have a complex return, the IRS recommends using their Withholding Calculator for your W-4.
