There is one way to get a little extra money-- and I'm not being personal to you, anyone might be helped by this,,,A lot of people do not know you can change your withholding at work at any time. If you are a single mom, 2 kids in day care and don't make much money, you're probably going to get a credit for child care, a credit for each child, file as head of household and an earned income credit. If you are not putting exempt or 3 or 4 on your w4 you might be having way too much withheld.
There is a calculator on the IRS website that you plug in figures from your current paystub and it will tell you about where you are with regards to owing/refunding at the end of the year. It will say, " based on our calculations, you will be receiving approx $$$xxx (or whatever) in a tax refund. You may change your withholding to 9 exemptions and will then receive about $$xxxx for a refund."
Also, if you are making just a little money, you can make an appt at the Salvation Army and ask for help paying your electric bill, then that $$ will go for day care.
Also, most importantly, apply for SNAP and AFDC right away--and try to get free lunch for your children. By law they have to give you emergency food stamps (Snap) you have less than 100.00 and some other qualifications (like suddenly bringing in less than your bills- I don't know the particulars. You no longer have to take off work for this- it's done electronically and then they interview you over the phone.
I hope no one is thinking I am trying to say anything bad, I'm just saying you are a hard working Mom who is having a crisis and that is what the govt aid is supposed to be for.....
