What I really need to figure out now is:
How do we find out if my husband was considered a long-term resident?
How do we find out if his green card was considered abandoned by Homeland Security, considering an immigration officer considered it abandoned six years ago? I've read that if HS considers it abandoned, that means it ended his period of long-term residency.
The IRS site says "long-term residents who have terminated their long-term resident status for tax purposes must file a Form 8854". What do they mean by "for tax purposes"? Their wording is confusing - are they referring to LTR's who abandon FOR tax purposes, or are they saying that for tax purposes an LTR must fill out form 8854?
Apparently, he did file a return in 2007, so if his LPR status was considered abandoned in 2006 as the IO told him it was, he would be fine.
Thank you everyone for your help. Once I find out those above questions, things should be a bit easier. This has become an absolutely ridiculous situation. I simply thought I owed one or two years of returns, and now this has turned into an incredibly stressful situation for me. The US is the only country in the world that does this to its expats, besides Eritrea, who a Canadian court ruled was acting illegally requiring taxes from their citizens abroad. My rant is over. Thanks again.
Also, sorry for ALL the questions. Everything online gives advice on how to keep a green card while living abroad. We want to get rid of it! On this site (http://www.visalaw.com/99oct/20oct99.html) I've found something that says "failure to file a return is almost always considered a sign that LPR status has been abandoned" - wouldn't nearly 7 years of absence and not filing a return be considered an abandonment?
So, according to this new policy, US citizens living abroad who were unaware they needed to file tax returns and FBAR's won't be penalised as long as they file when they learn they need to. I think we should stop scaring people here into thinking the IRS is going after them, when they owe no money.
As has been stated, the rules for abandoning a GC for IMMIGRATION purposes is DIFFERENT from the rules for TAX purposes. All the links/advice that you are using just justify that he has abandoned don't necessarily apply for tax purposes.
As has also been stated and linked, your husband may fall under one of three sets of rules. No one here can properly advise you without knowing which of the three rules he falls under. Those of us that are tax professionals would be wise not to advise you further on this subject because we do not understand the full fact pattern and it is an immensely complex area.
So for your question, how can you determine if he is still a long term resident. First, figure out which rules apply. Then look at those rules and see what was the criteria for abandonment. Then also see what are the follow up tax requirements after abandonment. For example, old rules required you to continue to file tax returns for 10 years following abandonment. Newer rules require the 8854 and calculation of an exit tax. I have already posted the link to the three sets of rules.
As for your situation, if you are only delinquent on tax returns for two years and won't owe tax and not yet delinquent on FBARs, you may be fine for penalties. As nun is trying to politely say though, you better make sure you have a strong understanding of your situation and truly don't owe. We see people treat UK pensions, ISAs, etc. wrong all the time and assume there is no tax impact or the tax impact is the same as if it were a US pension, etc. If you do owe tax or are delinquent on FBARs, it is not an accurate statement that you will be fine as long as you file now. You are taking those quotes out of context and I can assure you I have seen folks severely penalised in a personal and professional capacity.
Also while your situation may seem straightforward, if your husband still should have been filing, then you have some decisions to make on your taxes. For example, maybe it is better for you to file jointly, if your husband will owe money. This is why you have been given advice to consider your circumstances as a family unit.
Further no one can tell you if you need to attach anything else. You can file delinquent returns in a number of ways (as guya listed). Your decision on how to file will determine if you need to attach something else. Your decision on how to file needs to be carefully thought out based on how certain it is that you don't owe anything and that your husband is filing correctly. It also depends on how much risk you are willing to bear. Recognise if you want to make use of the new program, it is specifically something you have to ask for, it doesn't automatically apply to you.
And given that your posts are now picking advice out of context and referring to websites out of context, I can no longer give you any further advice myself or I may be come partially liable to your situation. As you seem to think this is all straightforward and we are scare mongering, you won't need our advice any further anyway. All the best.
