If you did not get a W-2 from your employer, use the IRS TeleTax system at 1-800-829-4477, topic number 154, to find out what you need to do. If you have lost your W-2 or it is incorrect, ask your employer for a new one.

Yes. See Arizona Form 200, Request for Innocent Spouse Relief and Separation of Liability and Equitable Relief. Use this form if you are an innocent spouse (a person that has filed a joint return who is requesting relief from joint and several liabilities). Do not use this form if you are an injured spouse (a person whose share of an overpayment shown on a joint return was, or is expected to be, applied against that person's spouse's past-due state taxes, child support or spousal maintenance, or debts owed to another Arizona state agency).

The department needs Form 140ES for proper application of your estimated tax payment to your account. If estimated tax was underpaid or paid late, a penalty will be charged.

You will have to complete and submit an amended tax return Arizona Form 140X.
