<prompt> Human: Changed my W-4 exemptions to 4. My wife, 2 kids and myself. From the worksheet I should claim 8. It all seems ridiculous and confusing but even at 4 exemptions Im not losing any federal income tax. Can anyone explain this a bit?Edit: clarify that wife doesnt work, social security and Medicare are being deducted just not federal income tax.  <response>: If your only making 35k and have kids then you will not owe anything and I guarantee you that you will get a large refund. The EITC and Additional Child Tax Credit.
