Do you lose your tax refund for filing chapter 7 bankruptcy in Washington OR ANY state?

Very likely...the refund is because you had more money than needed withheld from your paycheck and pu in (essentially) a savings account at the IRS to pay your eventual liability. This money, earned and saved pre-filing, had you not had it put aside (or had you correctly estimated and completed the W-4 so the right amount was withheld), would have been available to pay the creditors. You know, you could literally have had 100% of your pay withheld....think it makes sense youc could get and keep it after filing BK? Of course, as BK is Federal Law, and in a FEDERAL court, the State makes no difference. And of course, the Court has some discretion in these things too.
