I work,live in Asia file foreign tax credit.I wrote my old US address on my return,CT. state wants me to pay taxes.Can I amend my tax return to correct foreign address?

You do not need to amend your return to update your address.  Instead, you can use the following forms to update your address with Connecticut's Department of Revenue Services and the IRS:  Connecticut Form CT-8822 and IRS Form 8822.

Please note that changing your address alone will not likely be enough to respond to Connecticut's request for taxes due.  You should still timely respond to any correspondence that you receive from the state and explain your situation.
