Is my CPF taxable in the US?
Short answer: For US citizens and green card holders, CPF is not a US-qualified retirement plan, so US tax may apply to employer contributions and to growth inside the accounts even though the money is locked until later life. There is no treaty to override this, so the reporting position should be chosen deliberately with a US tax preparer.

Why it works this way
CPF is mandatory for Singapore citizens and permanent residents. From the IRS's perspective it is a foreign arrangement, and some practitioners treat it as a foreign grantor or employees' trust, which changes how contributions and growth are reported.
CPF balances count toward FBAR and Form 8938 thresholds in many interpretations, and the reporting obligations apply every year whether or not you withdraw anything.
Positions differ between practitioners because the guidance is thin. Consistency year to year and a documented rationale matter more than finding the most aggressive answer.
The expensive mistake: Leaving CPF off US returns entirely
Not reporting CPF on FBAR or Form 8938 can create penalties that far exceed the tax at stake. Report it, then argue the tax treatment.
What to do
- Get a written position from your US preparer — Agree how contributions, growth and reporting are handled and keep it consistent.
- Add CPF to FBAR and Form 8938 — Use year-end balances converted at the Treasury rate.
- Plan withdrawals with US tax in mind — Know the US tax treatment before taking CPF withdrawals at 55 or later.
