You might have to spell it out for me. I was kind of leaning towards filing jointly in the years leading up to my wife getting her pensions.
A very reasonable question and I’ve had a rather restless night trying to figure a way to respond. These conversations force one to analyse their own opinions. I’ve decided to answer as follows:
Married filing separately versus married filing jointly
Choice:Some will have no choice. Durham lad has no choice. Nun doesn’t have the problem. I on the other hand, do have the choice since I’m married to an NRA. You, F4m, may or may not have a choice. Does Mrs F4m have a Green Card? If so, will Mrs F4m jump through all the hoops required to no longer be subject to IRS filing? An individual, who has a Green Card, disposes of it properly with US Immigration and moves to the UK, but was an LTR in the US, may still have an IRS obligation if they have not filed the proper IRS form (8854 for the Exit Tax). If they still have an IRS obligation (and are therefore a US Person) married filing jointly may make sense.
Source of income:Is the MAJOR proportion of your pension income and investments from the US, or from the UK/EU? Most on this site have the major proportion of their income from the UK; so generally, it makes sense to file ‘married-separately’ when married to an NRA. (The reasons will come later.) In your case, F4m, the major proportion of your family income will come from the US as it stands now (again, more on this later). Married filing jointly will be a consideration for you.
The major proportion of my pension income (90%) and investment income (100%) come from the UK/EU. It makes sense for me to file married-separate, allowing my NRA wife to invest normally. Mrs OAP can find no logical reason to hand over her private financial data to a foreign government, and she wouldn’t show the data to me anyway. I have tons of FTC’s, as long as I make sure most of my income sources fall under 1116.
There’s also the problem of one’s culture. A US-centric individual has a survival instinct based on all type of market based investments (and a need for market based investments); cash savings yield no tax benefits; available deductions, itemised deductions, thresholds for % brackets, AGI, and on and on as required for existence in the US tax environment. For the UK/EU-centric filer, market based investments are required much less and cash savings can yield substantial tax benefits. On a 1040 the filer has few advantageous deductions, there’s usually little logic to filing itemised deductions, and thresholds and % brackets mean nothing since they have ample FTC’s to offset most, if not all, tax due (unless they fall under NIIT).
What is lost by filing married-jointly:First of all, a non-US Person (an NRA spouse), resident in the UK, can invest in any and every type of bank or investment account on offer. A US Person will be prohibited from acquiring a few of the accounts available. The situation may become more pronounced as FATCA slowly unwinds over the next 2 to 3 years.
Of the following list, a US Person can partake of all the sources of income, but the tax free status will be lost and the onerous form filing required for certain sources on a US return will become ‘The Journey from Hell’. If you employ an accountant, they will seek adequate compensation to accompany you on the Journey.
A non-US Person NRA spouse can: have a cash ISA, tax free; have a stocks and shares ISA, tax free: have an NS&I special high interest account for pensioners; invest in any unit trust offering; invest in any high interest bank account with split cash/unit trust offerings; invest in any PFIC type investment; have SIPPs; invest in a UK business; become a partner in a UK partnership; sell a primary residence for a profit, tax free; collect and resell a non-business automobile for a profit, tax free; receive any UK Government or local Council benefit (these are too numerous to list separately, and some are for every day needs) , often tax free; have a winter fuel payment, tax free; win the lottery, tax free; and on and on.
Moving the source of major income:If you are to be resident in the UK for the rest of your life, do you still want the major source of your income from the US? This is a serious question. I’ll avoid going into the prognostications of economic growth and pitfalls of the US versus the UK/EU. The UK economy runs on the Pound Sterling. Exchange rates WILL vary. Over the long haul, they usually even out, but having a DEPENDABLE amount of funds from an income source within the UK is reassuring for your day to day financial comfort.
Renouncing US citizenship, with a majority of foreign sourced income:I’m not going to go into this, other than to say will you still want, and be capable of, staying on top of US tax filing when you’re 85? Would your finances support professional assistance at 85? What is your goal, simplicity or complication? A number of individuals of our age are considering this option, seriously.
OTHER COMMENTS – It would be good if others who have been resident in the UK with an NRA spouse could comment if they feel filing married – joint is the better option.
