Time for a rebuttal.
(This will not surprise nun. We’ve had this discussion many times over the years. Unusually, this is one of the very few topics where we do not agree fully.)
So, to start with, I agree with nun; but only with the statement that US SS benefits, for contributions within the US SS programme, are progressive. That’s the extent of agreement.
First, for the expat, US SS is the classic Catch 22. The WEP information states:
“If you work for an employer who does not withhold Social Security taxes from your salary….”
The implication is an option exists, and you can work for an employer that will withhold Social Security taxes. As an expat, and forgetting certain unique circumstances (Totalisation Agreement, self-employment), you do not have a choice. No foreign employer participates in US SS. WEP becomes an automatic penalty when you move abroad and pursue pension planning where non-US programmes are involved. Like US taxes for the expat, US SS is US-centric. Non-SS work in the States (Federal, State, and local authority pensions for example) compensates the employee with generous terms to offset the loss of US SS. Review the Detroit bankruptcy saga if you doubt this. Foreign plans will not compensate loss of US SS. Why should they?
As an expat abroad, you do have one choice. You may elect to avoid all foreign pension planning and avoid WEP (a disadvantage for retirement). If you are employed in the UK on an average salary, this may be impossible. Your employer will withhold contributions to the UK State Pension.
Second, US SS may be progressive, but WEP is not. If you have a UK pension of £8,000/yr, for example, you will suffer maximum WEP ($413/month for 2015). If you have a UK pension of £80,000/yr, you will still only suffer maximum WEP of $413/month. WEP penalises those on lower pension incomes unfairly, and supposedly, that’s what the progressive nature of US SS attempts to avoid. Those suffering from low incomes in retirement are penalised even further by WEP, and they are the ones needing the funds the most to survive in retirement.
Third, unlike the UK State pension provisions, you cannot contribute voluntarily to US SS. If you are not working for a US employer, there is no way to protect yourself from WEP and attempt to participate in the progressive nature of US SS to bolster both the US SS reserves and a substantial US SS benefit. Not allowed.
Last, there are numerous examples where someone resident in the US can have significant retirement benefits, voiding the progressive nature of US SS; retain the higher US SS progressive advantage when having contributed minimal amounts to US SS; and not be WEPed. Again, the assumption of the progressive US SS depends solely on all participants exercising the option of working within the US-centric system for up to 30 years in contributing US employment.
And........It's unlikely to change. Within every district and State in the US, most are convinced US SS is doomed. What are the chances of Congressional reform to equally benefit the expat? Nil would be my guess.
