Thank you for this. It looks like we do qualify for the streamline procedure. I'm just wondering if it would be better for us if we paid someone to deal with it for us as I'm so worried about getting it wrong because, from the looks of it, you get one shot!
First, if you owe no US tax (likely in your case due to the offset of UK tax paid or the FEIE) there will be no penalties involved. It becomes a paper filing exercise, but, it must be done correctly. Many have done this themselves with no unpleasant consequences.
It will all depend on your aptitude for filing US tax returns.The instructions for filing the Offshore Streamlined Procedures can be found at the following:
https://www.irs.gov/individuals/international-taxpayers/u-s-taxpayers-residing-outside-the-united-statesThe appropriate tax forms for each of the 3 years required can be downloaded from the IRS site. Use the appropriate forms for each of 2018, 2017, and 2016. The basic kit for a yearly return, in your case, would be form 1040, Schedule B, form 2555 (FEIE), and form 8965,
provided your husbands income is below the FEIE threshold. If over the threshold, or by choice, the alternative is to use form 1116, Foreign (UK) Tax Credits. You'll need to assess your finances carefully to be sure these are the only forms required. (Husband is not self employed, has less than $200,000 in assets, pensions, etc.). Your husband would likely file MFS (Married Filing Separate). Doing so means your finances are not included in the returns.
As for FBAR, 6 years are required, but although you may not have the requisite amounts for filing, it may be wise to file the 6 anyway in order to make sure the three 1040 filings are accepted without delay. FBAR filings are made separately to the tax forms, and are made on the US Treasury FBAR site.
https://bsaefiling.fincen.treas.gov/NoRegFBARFiler.htmlThe IRS have published acceptable exchange rates for each year for the tax forms. The FBARs use a different yearly rate, found on the Treasury site.
You will also have to file form 14653 with each filing. Read the instructions and compose your response carefully.
Once you have done the procedures, you must be sure to complete a US return every year from now forwards.
