I guess there must be a very effective accountancy lobby in the USA that is interested in maintaining itself! ![Grin ;D](https://www.talk.uk-yankee.com/Smileys/classic/grin.gif)
I've never once heard any CPA complain!
I'm aware of the cost of a renunciation application, hence my question about the number of years of returns I need to make. If it's 5 years of returns, then I guess I can make my last 3 years of returns under the streamlined procedure, then make annual returns for the next two years, and renounce in 2019/2020?
Yes, that is correct.
FinCEN...? Is that the FBAR thing? So I can't do an FBAR along with my tax return to the IRS, it has to go somewhere else?
Yes, FinCEN refers to what in the past was the FBAR. It's now FinCEN form 114. FinCEN stands for the Financial Crimes Enforcement Network, but don't be alarmed, all who have foreign financial accounts totalling an
aggregate of $10,000 must file this.
http://bsaefiling.fincen.treas.gov/NoRegFBARFiler.htmlLet's try to answer some of your questions.
Streamlined filings must be submitted on paper. That doesn't prevent you from using online software and then printing the resulting forms off and mailing them in. Free File may work for you, but there are limitations on income, age, and foreign residence according to which you might be able to use.

They will walk you through form filling, but you will need a basis of understanding to make sense of them. It's probably best to start with Publication 54.
https://www.irs.gov/pub/irs-pdf/p54.pdfI hope you have a tolerance for reading somewhat stupefying language because you'll need that basic understanding.
Cost for professional preparation can range from $400
per year (the cheapest I've heard of, and cheap may be an appropriate word) to $thousands.
You need a separate return filed for
each year.
Before starting, review what types of income and investments you may have. Some income is earned (a salary), and some may be passive (child benefits). Some investments (Stocks and Shares ISA) are toxic, and others (normal savings account or Cash ISA) are simple. What is tax free in the UK will likely NOT be tax free in the US.
You've not mentioned your marital status, but most persons married to a non-USC (UKC for example) file 'Married Separate'.
A basic starter kit, depending on your unique situation, would be:
Form 1040:
https://www.irs.gov/pub/irs-pdf/f1040.pdfand instructions:
https://www.irs.gov/pub/irs-pdf/i1040gi.pdfProbably Form 2555: (tax free for 'earned' income up to $100,000+)
https://www.irs.gov/pub/irs-pdf/f2555.pdfand instructions:
https://www.irs.gov/pub/irs-pdf/i2555.pdfPossibly form 1116: (for 'passive' income taxed by HMRC for tax credits against US tax, OR, for 'earned' income taxed by HMRC if you wish to file this form instead of 2555)
https://www.irs.gov/pub/irs-pdf/f1116.pdfand instructions:
https://www.irs.gov/instructions/i1116/index.htmlIf you have any bank accounts in the UK (current or savings) you'll need to file Schedule B, especially Part III:
https://www.irs.gov/pub/irs-pdf/f1040sb.pdfYou'll also need Form 8965 to be excepted from paying a penalty for not having US health insurance: (yes, it defies logic!)
https://www.irs.gov/pub/irs-pdf/f8965.pdfand instructions:
https://www.irs.gov/pub/irs-pdf/i8965.pdfYou may also find this publication useful:
https://www.irs.gov/pub/irs-pdf/p17.pdfYou will not need to file any State tax form.
Hope this gets you started, but review your situation carefully and how you wish to proceed.
