Now, we have previously written about UK pensions https://htj.tax/?s=uk+isa
Recently we have been asked – “ Are you able to confirm whether or not a UK PCLS is taken tax-free in the US? I’m seeing loads of conflicting answers online as some believe it is not taxed at a Federal level but may be taxed at State level?”
Our thoughts on this controversial area were expressed here – https://htj.tax/2020/10/us-taxation-of-uk-pension-plans/
Another question – “What about SIPPs”
With regards to SIPPs, many providers employ a trust structure, which as mentioned in reportable. As to whether it is taxable? It will only receive protection under the tax treaty if it is “wrapped” as a pension plan in the UK, meaning it complies with certain rules. However, there are rare situations where it’s more tax efficient to NOT invoke the tax treaty. If you do invoke the treaty then contributions and gains will not be taxed until distribution. If you do not, then contributions and gains are taxable, but you may get a Foreign Tax Credit on your US taxes. Lastly, there is the issue of US states. This could, for instance, mean that dividends within a SIPP are subject to state taxes – even if they are exempt at the federal level because tax treaties are Federal not state level.

Foreign pension plans in general
- Employees’ trust: If a pension plan is more than 50% funded by the employer and the plan does not favor highly compensated employees, the foreign pension is considered a nonexempt employees’ trust and governed by Sec. 402(b). In that case, employer contributions are generally taxable income to the employee, but growth inside those plans is tax-deferred until distribution. Upon distribution, the fund functions like an annuity under Sec. 72, and the taxpayer would be allowed to recover his or her basis (contributions) as a return of capital. However, if one of the reasons a trust is nonexempt from income tax is a failure of the plan to meet the participation requirements of Sec. 401(a)(26) or the coverage requirements of Sec. 410(b), then a highly compensated employee shall, in lieu of the contribution amount to the plan under Sec. 402(b)(1) and distributions from the plan under Sec. 402(b)(2), include in gross income an amount equal to the vested accrued benefit as of the close of the tax year of the trust. Thus, the highly compensated taxpayer will end up including in gross income the incremental increase in the value of the plan as of the end of each year. The meaning of “highly compensated” for these purposes is set forth in Sec. 414(q). This amount is adjusted for inflation each year and for 2020 equals $130,000.
- Grantor trust: If a retirement trust is funded entirely by the taxpayer rather than an employer, then the trust will be a grantor trust for U.S. income tax purposes. All items of income, deduction, and credit would appear on the taxpayer’s individual income tax return as if the taxpayer owned directly the assets of the retirement trust.
- Bifurcated trust: Generally, by definition, an employees’ trust is not a grantor trust as to the employee participant. However, if more than 50% of the contributions are made by the employee, the trust is considered to be bifurcated for U.S. tax purposes: The amounts contributed by the employer constitute an employees’ trust, and the rest of the contributions made by the employee participant are classified as a foreign grantor trust.
While the United States generally taxes its residents on their worldwide income regardless of their citizenship or the source of the income, an income tax treaty to which the United States is a party could modify the usual rules and mitigate some of the disadvantages of participating in a foreign pension plan.
The tax treaty between the United States and the United Kingdom, which this item focuses on, is one of the most comprehensive when it comes to pensions. Pension provisions are set forth in Articles 17 and 18.
Taxation of retirement plan contributions
Alternatively, the U.S. national, while living and working in the U.K., can continue to contribute on a pretax basis to his or her U.S. 401(k) plan, provided that the individual was already enrolled in the U.S. plan prior to his or her departure (Art. 18, ¶¶2a and 3a). Furthermore, under the tax treaty, employer contributions to the employee’s pension do not constitute compensation and are considered a business expense in computing the employer’s profit and loss (Art. 18, ¶2b).
The treaty thus allows transferred employees to continue to contribute to their home country pension plans without having the employer portion of the contribution be considered taxable income in the host country. Additionally, both employer and employee contributions to the home country pension plan are tax-deductible in the host country (Art. 18, ¶¶2a and 2b).
Certain conditions apply:
- The limits of the host country govern. For example, if a U.K. national works in the United States and continues to participate in a U.K. pension plan, he or she cannot deduct more than the limit prescribed in the United States (the host country) under Sec. 402(g).
- The employee must have already been participating in the home country pension plan before moving to the host country.
- The pension plan must be accepted as a generally corresponding pension scheme by the appropriate authorities in the host country (Art. 18, ¶2, 3).
Taxation of retirement earnings/growth
However, the U.S.-U.K. tax treaty alters this rule by clearly indicating that income earned by the pension scheme may be taxed as income of that individual only when distributed, meaning that earnings inside the plan are tax-deferred (Art. 18, ¶1).
What about rollovers?A U.K. national is allowed rollovers from one approved pension plan to another U.K. plan. Similarly, a rollover from a U.S. 401(k) plan is allowed to another, say, 401(k) or traditional IRA. By contrast, an individual cannot make a rollover from a U.K. to a U.S. plan and vice versa (see Chief Counsel Advice Memorandum AM2008-009, advising that a transfer from a U.K.-registered pension outside of the original state (the U.K.) is not an “eligible rollover distribution” under Sec. 402(c)(4)).
Special attention should be given to U.K. pension rollovers to offshore plans, such as the qualifying recognized overseas pension scheme (QROPS) and the recognized overseas pension scheme (ROPS) plans, which are offshore plans that are sometimes set up in countries such as Malta, Gibraltar, and the Isle of Man. Even though these are permitted under U.K. law, once these rollovers occur, they are no longer governed by the provisions of the U.S.-U.K. tax treaty.
Taxation of retirement distributions
Under a separate provision of the tax treaty that is expressly not subject to the saving clause, if an individual would have enjoyed tax-exempt status for all or a portion of the distributions in the home country, the host country will confer the same benefit (Art. 17, sub ¶1(b)).
