I am married and we file the married filing jointly. Just from my research only one of us can claim the allowance of 4. I do not want to owe as well so my wife claims 0 on her W4 and I claim 4. Also, she pays an additional $25 per pay period just in case. As this is my first time doing this I am going to adjust my W4 back to 0 in September just in case I was wrong and had too many allowances.
