I am a new single mom, in my house we are only my child and me.
In my W-4, what number should my number of allowances be?
Thanks!

Claim 1 for you, 1 for dependent, 1 for head of household, and 1 for daycare (if you pay for daycare abd have receipts to send to the IRS)
You should claim 4 w/daycare 3 w/out

If you did not have any tax on your 2008 tax return and do not expect to have any tax in 2009, then claim exempt.
