UK State Pension on Your Form 1040

As of August 2026, the full new UK State Pension is £241.30 a week. Using the IRS yearly-average pound rate of 0.759 for calendar 2025, that is about $16,532 a year — and the United States taxes the whole amount as a foreign pension, not as U.S. Social Security. The 50% / 85% Social Security worksheets in Publication 915 do not apply.

This is a supporting filing guide for people who already have, or will have, a UK National Insurance record and a U.S. Form 1040 obligation. It is not a second workplace-pension article. If you still contribute to a UK occupational scheme or SIPP, start with the UK workplace pension U.S. tax guide, then come back here for the State Pension line on the return. Retirees are the primary reader; operators still filling NI gaps and families with mixed U.S.–UK careers get the same reporting math.

The cash-flow lever is simple: keep the UK from taxing a payment the treaty assigns to your residence country, then convert pounds to dollars the same way every year so the IRS number is reconstructable. Browse other retirement-income pieces in Retirement Abroad after you lock this workflow.

Do I still owe US tax on a UK State Pension?

Yes, if you are a U.S. citizen or resident alien. The IRS treats foreign social security as a foreign pension or annuity unless a treaty says otherwise. Publication 915 states outright that it does not cover foreign social security, and that those benefits are taxable as annuities unless a treaty exempts them or treats them as U.S. Social Security.

The UK–U.S. treaty does not give UK State Pension the Canada/Germany treatment. You do not drop it onto the Social Security worksheet. You convert it to dollars and put the gross amount on the pension lines of Form 1040 (typically 5a / 5b), not on the U.S. Social Security lines (6a / 6b).

The foreign earned income exclusion does not shelter it

Form 2555 excludes foreign earned income. A State Pension is deferred social-insurance income, not wages. Claiming the exclusion on it is a mismatch, and it does not reduce the taxable pension. Self-employed readers who still have UK or U.S. earned income can use FEIE on the earned piece only; the State Pension stays on the pension line.

The same split applies to additional Medicare tax and net investment income tax: the State Pension is ordinary pension income, not wages and not NIIT portfolio income. Do not bury it in Schedule D or Schedule C.

How Article 17(3) assigns who may tax it

Article 17(3) of the 2001 U.S.–UK income tax treaty, as signed at London on 24 July 2001, says that social-security payments made by one country to a resident of the other “shall be taxable only in that other State.” In plain English: the UK State Pension paid to a person who is a U.S. treaty resident is taxable only in the United States. The 2002 protocol keeps paragraph 3 of Article 17 outside the saving clause, so the United States cannot ignore that assignment for its own citizens when they are U.S. residents receiving UK social security.

HMRC’s own non-resident rule matches the treaty for most filers who have left the UK: non-residents do not usually pay UK tax on the State Pension. That is why a U.S. resident often sees a clean U.S.-only tax, not a UK withholding certificate to credit.

Three residence cases, not one slogan

Where you are treaty-resident	Who taxes the UK State Pension	What the U.S. return usually does
United States	United States only (treaty Art. 17(3); UK generally does not tax non-residents on State Pension)	Report the full dollar amount as a foreign pension. No Foreign Tax Credit unless the UK actually assessed tax you legally owed.
United Kingdom	United Kingdom taxes residents. Article 17(3) applies to payments to a resident of the other country, so it does not by itself make the pension U.S.-exempt for a UK resident.	U.S. citizens still file a 1040 on worldwide income. Report the pension, then claim a Form 1116 credit for UK income tax actually paid on that income, subject to the credit limitation.
Third country (Spain, Portugal, Mexico, and so on)	The UK usually does not tax non-residents on State Pension. The U.S. still taxes citizens. The local country may tax residents under its own law and its treaty with the UK or the U.S.	Report the full dollar amount. Credit only foreign income tax you legally owed. Do not assume the U.S.–UK treaty’s exclusive-residence rule covers a Spanish or Mexican resident.

Data note: treaty text from the U.S. Treasury PDF of the 24 July 2001 convention; UK non-resident State Pension treatment from GOV.UK “Tax on your UK income if you live abroad,” checked August 2026.

Form 8833 exists for treaty positions that override the Code and reduce U.S. tax. The current Form 8833 instructions waive reporting for treaty positions that merely reduce or modify tax on pensions, annuities, social security, and other public pensions. A U.S. resident who simply reports the UK State Pension as fully taxable U.S. income is not taking a tax-reducing treaty override. Do not file 8833 for that fact pattern. If you later take a more aggressive position — for example, excluding a workplace-scheme lump sum under Article 17(1)(b) — that is a different disclosure, covered in the Form 8833 treaty-disclosure guide.

How do I report UK State Pension on Form 1040?

DWP will not send you a Form 1099-R. You still have to pick up the income. Keep every International Pension Centre payment advice, the GBP amount, the payment date, and the USD amount that actually landed if the payment was converted.

The IRS says it has no official exchange rate and generally accepts any posted rate used consistently. Spot rate on each payment date is the technically cleanest method. A yearly average from the IRS table is acceptable if you use it for the whole year and keep the table printout with the return. Do not mix methods mid-year.

1. Add every GBP State Pension payment received in the calendar year, including the December annual payment if your weekly rate is under £5 and DWP pays once a year.
2. Convert to USD with one documented method (spot per payment, or IRS yearly average for that calendar year).
3. Enter the gross USD amount on Form 1040 pension lines. Taxable amount equals gross; there is no employee-contribution basis in a UK State Pension.
4. If you are UK-resident and paid UK Income Tax on the pension, complete Form 1116 in the general limitation category. Credit only tax you legally owed after the treaty, not tax the UK should have refunded to a non-resident.
5. Do not put the figure on lines 6a/6b. Those lines are for U.S. Social Security and equivalent railroad benefits.

Operator path: if you split the year between the UK and the U.S., determine treaty residence under Article 4 before you decide whether Article 17(3)’s “resident of the other State” sentence even applies. Dual-resident filers who elect foreign residence under the treaty file Form 1040-NR with Form 8833 and can trigger section 877A issues if they are long-term residents. That is a specialist return, not a 1040 footnote.

Claiming, uprating in the USA, and the 0.39% conversion

You can claim the UK State Pension while living in the United States. GOV.UK requires you to be within four months of State Pension age to claim. Use the new State Pension international claim form (IPCBR1NSP if you reach State Pension age on or after 6 April 2016) and the USA payment form IPC1394, and send both to the International Pension Centre in Wolverhampton.

You need 10 National Insurance qualifying years to get any new State Pension, and 35 qualifying years for the full rate if your NI record started after April 2016. Earlier records can be reduced by contracting-out. A qualifying year is paid contributions, NI credits, or voluntary Class 3 contributions.

The USA is on the annual-increase list

The UK pays the State Pension worldwide, but the annual increase (triple lock: earnings, CPI, or 2.5%, whichever is highest for the new State Pension) only follows you if you live in the EEA/Switzerland or in a country whose social-security agreement allows cost-of-living increases. The United States is on that GOV.UK list. Canada and New Zealand have UK social-security agreements but do not get the yearly increase. That is a cash-flow fact when you compare retirement bases, not a tax election.

GOV.UK also states that if the pension is paid into an overseas account, the amount is usually converted at the then-current rate with a conversion charge of 0.39% before payment. U.S. federal-holiday weeks can delay the credit by one day because a U.S. company processes those payments. You must pick one country of payment; you cannot have DWP pay the U.S. for winter and the UK for summer.

If you want the dollars in a U.S. brokerage you can actually use from abroad later, a Charles Schwab brokerage plus checking setup is the usual landing pad after the IPC1394 USD credit hits a U.S. bank. That is a custody choice, not a tax form.

Totalization credits, FBAR, and Form 8938

The U.S.–UK totalization agreement lets each country count the other’s coverage to meet minimum eligibility. SSA’s UK pamphlet says you generally need at least six U.S. credits before U.K. credits can help a U.S. benefit, and at least one year of U.K. coverage before U.S. credits can help a U.K. basic pension. Each country still pays only on its own record. Totalization does not increase the UK State Pension rate; it can only help you clear the qualifying-year floor. Pair this with the U.S. totalization-agreement explainer if you are still short of 10 UK years or 40 U.S. quarters.

A UK bank account that receives the State Pension is a foreign financial account. File FinCEN Form 114 (FBAR) if the aggregate of all foreign accounts exceeds $10,000 at any time during the calendar year. The State Pension itself is income, not an account; the current account it sits in is the FBAR item.

Form 8938 is separate. Specified individuals living in the United States file when specified foreign financial assets exceed $50,000 on the last day of the year or $75,000 at any time ($100,000 / $150,000 joint). Specified individuals living abroad use $200,000 / $300,000 single or $400,000 / $600,000 joint. A UK current account can count; a U.S. brokerage that merely received a converted USD credit does not. Use the year-end Treasury translation rate for 8938 maximum-value tests, which is not the same as the income-conversion method on Form 1040.

Windfall Elimination is not this Form 1040 line

U.S. Social Security can still interact with a foreign pension under older Windfall Elimination rules, but Congress repealed WEP and GPO in the Social Security Fairness Act, with SSA paying the corrected amounts on benefits due after December 2023. Do not reduce the UK State Pension figure on Form 1040 because of WEP. If your U.S. Social Security award letter still looks wrong, that is an SSA operations issue, not an IRS pension-line issue.

Filing checklist before you hit send

Work this sequence once, then reuse it every April.

1. Download the DWP / International Pension Centre payment history for the calendar year.
2. Confirm you claimed with IPCBR1NSP (or the old-rules form if you reached State Pension age before 6 April 2016) and that IPC1394 still points at the correct U.S. account.
3. Confirm whether you were UK-resident, U.S.-resident, or split-year. That choice drives Article 17(3) and Form 1116, not the GBP total.
4. Convert GBP to USD with one written method. If you use the IRS yearly-average table, save the page for that calendar year.
5. Enter the USD total on Form 1040 pension lines. Leave Social Security lines for SSA-1099 amounts only.
6. Credit UK tax on Form 1116 only if you were actually UK-taxable on the pension.
7. Test FBAR at the $10,000 aggregate and Form 8938 at your specified-individual threshold.
8. If you still have a UK workplace scheme, keep those statements off this worksheet and on the workplace-pension file.

Conclusion

The expensive mistake is treating the UK State Pension like a smaller U.S. Social Security check. It is a fully taxable foreign pension on Form 1040, converted to dollars, with treaty residence deciding whether the UK also has a claim. Report the gross, credit only real UK tax, and keep the DWP paper trail. The workplace scheme is a different article and a different worksheet.
