If you’re a UK citizen who has moved to the United States and are either receiving or planning to receive your UK State Pension, it’s important to understand how this income is treated for US tax purposes. Navigating the interaction between the two countries’ tax systems can be complex, but with the help of the UK-US tax treaty and some clarity on domestic rules, you can stay compliant and potentially avoid double taxation.

Overview of the UK State Pension

The UK State Pension is a government-provided retirement income available to individuals who have paid sufficient National Insurance contributions during their working life. It is paid periodically, typically every four weeks, and forms a key part of retirement income for many UK nationals.

Is the UK State Pension Taxable in the US?

Yes, for US tax purposes, the UK State Pension is considered taxable income. As a UK citizen resident in the US (and assuming you are a US tax resident, whether through citizenship, green card status, or substantial presence), you are generally required to report and pay tax on your worldwide income, including foreign pensions.

This means your UK State Pension must be included in your US tax return (Form 1040) as income. The amount should be reported in US dollars, using an appropriate exchange rate for the tax year in question.

Role of the UK-US Tax Treaty

The UK-US Income Tax Treaty helps alleviate the risk of double taxation and provides guidance on which country has taxing rights over certain types of income.

Under Article 17 (Pensions and Annuities) of the treaty, pensions and similar remuneration paid to a resident of one country in consideration of past employment are taxable only in the country of residence. This means:

If you are a UK citizen residing in the US, and you receive the UK State Pension, the US generally has the exclusive right to tax that income. The UK does not tax the pension once you are a non-resident, though it is good practice to inform HMRC of your non-residency status to ensure proper tax treatment.

Practical Reporting Considerations

Convert currency: Convert UK State Pension payments to US dollars using an annual average exchange rate or the rate at the time of each payment. Reporting method: Report the income on Line 5a and 5b of Form 1040 under “Pensions and Annuities.” Taxable portion: Since the UK State Pension is not treated like a qualified plan in the US, the entire amount is generally taxable.

Are There Any US Tax Deferral Options?

Unlike some employer pensions or private retirement plans that may qualify for tax deferral in the US under certain treaty provisions or IRS rules, the UK State Pension does not generally benefit from such treatment. It is taxed as received.

State Tax Implications

Depending on your state of residence, your UK State Pension may also be subject to state income tax. States like California and New York tax all income regardless of source, whereas states like Florida and Texas have no state income tax.

Final Thoughts

UK citizens living in the US should be aware that their UK State Pension is reportable and taxable under US law. The UK-US tax treaty helps avoid double taxation by assigning taxing rights to the US. Proper reporting on your US tax return is essential to remain compliant and avoid any penalties.
