Tax-deferred employer plans

The Central Provident Fund (CPF) is Singapore's mandatory savings scheme. Employer and employee each contribute (rates vary by age bracket; up to 17% employer and 20% employee for those under 55). CPF has four account types: Ordinary Account (housing, insurance, investment, education), Special Account (retirement savings; closed for members aged 55 and above since January 2025, with balances moved to the Retirement Account up to the Full Retirement Sum and the remainder to the Ordinary Account), MediSave Account (medical), and Retirement Account (payouts from age 55 onward). The exemption is available only to an ‘eligible individual’ under §5.02: someone who is compliant (or comes into compliance) with U.S. income-tax filing and has reported the plan’s contributions, earnings, and distributions as income to the extent U.S. law requires; a participant who never reported plan earnings cannot rely on it until they do.

§301.7701-7 classification: Likely a foreign trust. The CPF holds segregated assets for individual members under a statutory trust arrangement. The CPF Board administers the fund under the Central Provident Fund Act. No published IRS ruling addresses the CPF directly, but the prevailing practitioner position treats it as a foreign trust.

Rev. Proc. 2020-17 analysis: Rev. Proc. 2020-17 does not require a tax treaty, so the absence of a U.S.–Singapore treaty does not by itself disqualify the CPF. CPF is tax-favored in Singapore, reports to the Singapore authorities, and limits mandatory contributions to a percentage of wages. Its Ordinary Account withdrawals for housing and education fall within, or are closely analogous to, the carve-out in Section 5.03(5), which treats withdrawals for hardship, educational purposes, or the purchase of a primary residence as permitted. Two features remain open questions: CPF allows full withdrawal on permanent departure from Singapore, which is not a listed reason, and it accepts voluntary cash top-ups that are not tied to earned income, which bears on Section 5.03(3). MediSave withdrawals for medical expenses are not listed either, though they are closely analogous to hardship. No IRS guidance addresses CPF. Practitioners should analyze each condition; the conservative approach is full reporting.

Treaty provisions: There is no U.S.–Singapore income tax treaty, so no treaty-based deferral is available for CPF earnings. This is a separate question from the Rev. Proc. 2020-17 reporting exemption.

3520/3520-A treatment: File Form 3520-A and Form 3520 Part II annually for the part your own contributions fund, once your own contributions exceed the employer’s, counted as the note at the end of this section explains (Treas. Reg. §1.402(b)-1(b)(6)), or for any part you otherwise own. Report contributions across all accounts, interest credited (CPF pays different rates for OA, SA, MA, and RA), and any government top-ups or grants. CPF withdrawals (housing, medical, retirement, permanent departure) go on Part III unless reported as compensation income (see the note at the end of this section).

For a plan an employer contributes to, a trust holding it is generally a nonexempt employees’ trust described in §402(b). §6048(a)(3)(B)(ii) excepts transfers to §402(b), §404(a)(4), and §404A trusts from Part I, the participant’s own contributions included, and §679 does not make the participant the owner (see the Reporting Guide’s employer-plan section). Payouts the participant reports as compensation income are excepted from Part III. If the participant’s own contributions ever exceed the employer’s, the participant is treated as the owner of the part those contributions fund (Treas. Reg. §1.402(b)-1(b)(6)), reports it on Part II and Form 3520-A each year it is owned, and is taxed on its income each year. In that count, what the participant chose to put in, salary sacrifice included, is the participant’s, and anything the plan’s rules required taken from pay is the employer’s, as the IRS chief counsel read a national retirement fund in 1997. The rest is taxed when it vests and, after that, when paid out (§402(b)(1), (2)).

Tax-deferred individual plans

The Supplementary Retirement Scheme (SRS) is a voluntary tax-advantaged retirement savings scheme. Contributions are tax-deductible in Singapore (up to a cap). SRS funds can be invested in stocks, bonds, unit trusts, fixed deposits, and insurance products chosen by the member.

§301.7701-7 classification: Likely a foreign trust. SRS accounts hold investment assets for the benefit of the member in a statutory framework. The trust classification is straightforward given the segregated, funded nature of the account.

Rev. Proc. 2020-17 analysis: SRS is a voluntary, individual, self-directed account rather than an employer-sponsored plan, so the employer-plan nondiscrimination condition (Section 5.03(6)) does not apply. It must instead be tested against conditions (1)–(5): SRS is tax-favored and reported locally, but contributions are not limited to earned income (Singapore citizens, permanent residents, and foreigners aged 18 or over may contribute, in cash, at any time) and early withdrawals are permitted subject to a 5% penalty, which satisfies the penalty prong of Section 5.03(5). The earned-income condition is the likely obstacle.

3520/3520-A treatment: Full reporting required. File Form 3520-A and Form 3520 Part II annually. Report contributions, investment returns, and the opening/closing balance. If the SRS holds non-U.S. unit trusts, PFIC rules may apply to them; we do not determine PFIC status or whether Form 8621 is due.

Gifts and inheritances

Singapore abolished estate duty for deaths on or after 15 February 2008 and does not impose gift tax. U.S. persons with family ties to Singapore may receive substantial gifts or inheritances. If a U.S. person receives more than $100,000 in gifts or bequests in a year from one nonresident alien individual or foreign estate (adding together gifts from donors related to each other), Form 3520 Part IV reporting is required. Gifts from foreign corporations or foreign partnerships exceeding $20,573 (for 2026, indexed for inflation) are also reportable.

Common scenarios include cash gifts from parents, inheritance of Singapore property, and distributions from family-controlled entities.

Penalties and practical notes

CPF annual statements are available through the CPF website and provide the data needed for the 3520-A. Singapore uses a calendar tax year: no conversion needed.

CPF contributions are mandatory for Singapore citizens and permanent residents who are employed. U.S. persons who are Singapore PRs will have contributions deducted automatically.

There is no treaty deferral. SRS earnings are taxable in the U.S. each year, since the member funds the SRS. CPF follows the employer-plan rule: contributions, the mandatory share taken from pay included, are taxed when they vest (§402(b)(1)), and growth after that when paid out, under §72 (§402(b)(2)). CPF earnings are taxed each year only on a part the member owns, which takes voluntary contributions above the employer’s total, or for a highly compensated employee whose employer leaves many rank-and-file employees out of CPF (§402(b)(4)(A)). Convert SGD at the rate prevailing when each amount is received, paid, or accrued; the IRS has no official exchange rate and generally accepts any posted rate used consistently, so its published yearly average rate is a common choice for amounts arising evenly across the year.

U.S. persons leaving Singapore may withdraw CPF under permanent departure provisions. It goes on Part III unless reported as compensation income (see the employer-plan note above), and is taxable to the extent it includes untaxed earnings.
