1. Does he need to file the delinquent tax returns before this one is due, or can we do this one then do the delinquent ones after (or all at the same time?)
It's already too late for timely 2016 filing, so you might wait until you file for 2017. File it first, and then follow up later with the 3 delinquent forms. That way, you only do 2014, 15, and 16 for streamlined. The delinquent forms have special markings ("Streamlined" in red at top and cannot be E-filed, I believe.)
I understand you may not be above the threshold for FBAR (FinCEN 114), but if he has signature authority over
any foreign bank account, it might be wise to file (online only) the last 6 years to verify you are complying with the Streamlined rules.
2. We are trying to decide between 2555. (Foreign income exclusion) and foreign tax credits 1116. I think we need 1116 as we have a child and this would allow us to claim for up to $1000 a year for past three years. Is this right?
Yes, you would have to use 1116 to claim the child credit.
Would he file on for each year missed? He earns around £25000 a year.
Yes, 2014, 15, and 16.
3. If he files under foreign tax credit and has only earned it the U.K. Am I right in thinking there is no way he can owe the IRS?
It's unlikely he would owe any US tax, but it all depends on your particular situation and assets. It's a myth that no one
ever owes the IRS tax due. Sometimes people do have to pay. We can't guarantee no tax due without knowing completely all of your details (
and we don't want to know!).
4. Is there a pro forma to claim non willful conduct for non filing?
As you mention below, 14653. That's the only statement required, but it must be included.
5. To claim additional child tax credit, will we only be eligible for this year because we will be on time or can we claim for missed two years as well?
Why not claim for all years. I believe it is allowed on delinquent returns. If the IRS disagree, they will simply refuse payment and it should not compromise the remdinder of your filing.
Do you need a foreign bank account for this?
No. The IRS only deals in $US.
6. How do you break down taxes for 1116? It seems easy enough to figure on the delinquents as we can use P60s.
No, you cannot use a P60 (unless you are using the 'accrued' method for tax paid, which only a few of us would use). A P60 is for 6 April to 5 April. The US tax year is 01Jan. to 31 Dec. All income and reporting is on income, etc. for the US tax year. The 'cash method' of determining credits for UK tax paid is also the US tax year.
Is it best to wait for this again for this April's P60 before filing?
See above.
7. We haven't met requirement for FBAR so we can ignore this,
See above.
....... along with 3520, 5471, 8938 which it doesn't seem we need to either. Are there any forms I might have missed? I Have surmised the following from my research: 8812 for child tax credit for each, 1040 for each tax return, 1116 for each return, one copy of 14653 statement.?
Yes. You must definitely file a Schedule B (especially Part 3 if he had signature authority over
any foreign account). You also need to file form 8965 to be free of the ObamaCare penalty.
....... 8. I contacted a lawyer (just via a message board, we really can't afford to pay) who advised me to do a quiet disclosure rather than streamlining but when I googled this it seemed dishonest and that felt unnecessary and wrong. Anyone feel this in fact good advice I have misinterpreted?
I can't comment on this, although some do use that method. It could be risky as long as the Streamlined programme is available. (The non-wilful statement is important.)
All IMHO! I am not a professional tax person.
