On unemployment had taxes taken out.with new tax law would i file for a refund?

Yes it is possible that you could receive a refund.

For the unemployment benefits that you received last year you should receive a 1099-G from the state showing the total amount received during the year and the amount in excess of 2400 will be entered on line 19 page 1 of the 1040 tax form and added to all of your other worldwide gross income and taxed at your marginal tax rate.

You will also receive a withheld income tax credit for the amount was withheld and reported on the 1099-G by entering that amount on the page 2 of the 1040 tax form line 61 Federal income tax withheld and added to any other federal income tax that was withheld from other sources during the year 2009.
