@leesm99pikl , since you have difficulties contacting IRS by phone from your location, you have two options (a) send in your response ASAP and with delivery confirmation if possible ( don't ask for signature because that will only delay things) -- keep record of your actions.; (b) if you are near an US embassy / consulate you can visit the local IRS branch -- they often have such a branch especially there is lots of expats in that country. They are usually very helpful. In any case just do the needful as soon as is possible. I am assuming here that you are disagreeing with the IRS' demands / position. If on the other hand you agree with position , then just pay and get it over with. Note however, that IRS is likely to look at yur returns for the next three years for compliance, especially if the amount due is large --
I hope this helps
