If you owe the IRS money (and are very late in paying) can legally request the US State Department not renew it or suspend your US passport. They also have in the past requested US Customs and Border agents to take your passport away from you when taxes are due and not paid. They will let you into the country but you cannot leave until you clear up your debt to the IRS. The rules are set forth HERE.
If you owe past taxes or tax returns we can help you avoid problems that may arise when you return to
visit the US. We have helped hundreds of taxpayers catch up and enter the IRS Streamlined Program. We can also assist you with an offer in compromise to reduce the amount of tax owed or a payment plan to pay your taxes off over time.
Our firm of attorney and CPAs have over 30 years experience in US expatriate, International and Nonresident taxation.
You may owe the IRS and not even know it! It is your legal obligation to keep them informed of any moves or new addresses. They are not responsible for keeping track of you or for poor mailing service.
