Pensions, Social Security, Annuities, Alimony, and Child Support

This Article deals with the taxation of private (i.e., non-government service) pensions and annuities, social security benefits, alimony and child support payments and with the tax treatment of contributions to pension plans.

Paragraph 1

Paragraph 1 provides that distributions from pensions and other similar remuneration beneficially owned by a resident of a Contracting State in consideration of past employment are taxable only in the State of residence of the beneficiary. This Model, unlike the OECD Model and the 1981 Model, makes explicit the fact that the term "pension distributions and other similar remuneration" includes both periodic and single sum payments. The same result is understood to apply in U.S. treaties that do not make this point explicitly.

The phrase “pension distributions and other similar remuneration” is intended to encompass payments made by private retirement plans and arrangements in consideration of past employment. In the United States, the plans encompassed by Paragraph 1 include: qualified plans under section 401(a), individual retirement plans (including individual retirement plans that are part of a simplified employee pension plan that satisfies section 408(k), individual retirement accounts and section 408(p) accounts), nondiscriminatory section 457 plans, section 403(a) qualified annuity plans, and section 403(b) plans. The Competent Authorities may agree that distributions from other plans that generally meet similar criteria to those applicable to other plans established under their respective laws also qualify for the benefits of Paragraph 1. In the United States, these criteria are as follows:

(a) The plan must be written; (b) In the case of an employer-maintained plan, the plan must be nondiscriminatory insofar as it (alone or in combination with other comparable plans) must cover a wide range of employees. including rank and file employees, and actually provide significant benefits for the entire range of covered employees;

(c) In the case of an employer-maintained plan the plan must contain provisions that severely limit the employees’ ability to use plan assets for purposes other than retirement, and in all cases be subject to tax provisions that discourage participants from using the assets for purposes other than retirement; and

(d) The plan must provide for payment of a reasonable level of benefits at death, a stated age, or an event related to work status, and otherwise require minimum distributions under rules designed to ensure that any death benefits provided to the

participants’ survivors are merely incidental to the retirement benefits provided to the participants.

In addition, certain distribution requirements must be met before distributions from these plans would fall under paragraph 1. To qualify as a pension distribution or similar remuneration from a U.S. plan the employee must have been either employed by the same employer for five years or be at least 62 years old at the time of the distribution. In addition, the distribution must be made either

(A) on account of death or disability, (B) as part of a series of substantially equal payments over the employee’s life expectancy (or over the joint life expectancy of the employee and a beneficiary), or

(C) after the employee attained the age of 55.

Finally, the distribution must be made either after separation from service or on or after attainment of age 65. A distribution from a pension plan solely due to termination of the pension plan is not a distribution falling under paragraph 1.

Pensions in respect of government service are not covered by this paragraph. They are covered either by paragraph 2 of this Article, if they are in the form of social security benefits, or by paragraph 2 of Article 19 (Government Service). Thus, Article 19 covers section 457, 401(a) and 403(b) plans established for government employees. If a pension in respect of government service is not covered by Article 19 solely because the service is not “in the discharge of functions of a governmental nature,” the pension is covered by this article.

The exclusive residence-based taxation provided under this paragraph is limited to taxation of amounts that were not previously included in taxable income in the other Contracting State. For example, if a Contracting State had imposed tax on the resident with respect to some portion of a pension plan’s earnings, subsequent distributions to a resident of the other State would not be taxable in that State to the extent the distributions were attributable to such amounts. In determining the amount of a distribution that is attributable to previously taxed amounts, the ordering rules of the residence State will be applied. The United States will treat any amount that has increased the recipient’s “investment in the contract” (as defined in section 72) as having been previously included in taxable income.

Paragraph 2

The treatment of social security benefits is dealt with in paragraph 2. This paragraph provides that, notwithstanding the provision of paragraph 1 under which private pensions are taxable exclusively in the State of residence of the beneficial owner, payments made by one of the Contracting States under the provisions of its social security or similar legislation to a resident of the other Contracting State or to a citizen of the United States will be taxable only in the Contracting State making the payment. This paragraph applies to social security beneficiaries whether they have contributed to the system as private sector or Government employees.

The phrase "similar legislation" is intended to refer to United States tier 1 Railroad Retirement benefits. The reference to U.S. citizens is necessary to insure that a social security payment by the other Contracting State to a U.S. citizen who is not resident in the United States will not be taxable by the United States.

Paragraph 3

Under paragraph 3, annuities that are derived and beneficially owned by a resident of a Contracting State are taxable only in that State. An annuity, as the term is used in this paragraph, means a stated sum paid periodically at stated times during a specified number of years, under an obligation to make the payment in return for adequate and full consideration (other than for services rendered). An annuity received in consideration for services rendered would be treated as deferred compensation and generally taxable in accordance with Article 15 (Dependent Personal Services).

Paragraphs 4 and 5

Paragraphs 4 and 5 deal with alimony and child support payments. Both alimony, under paragraph 4, and child support payments, under paragraph 5, are defined as periodic payments made pursuant to a written separation agreement or a decree of divorce, separate maintenance, or compulsory support. Paragraph 4, however, deals only with payments of that type that are deductible to the payor and taxable to the payee. Under that paragraph, alimony (i.e., a deductible payment that is taxable in the hands of the recipient) paid by a resident of a Contracting State to a resident of the other Contracting State is taxable under the Convention only in the State of residence of the recipient. Paragraph 5 deals with those periodic payments that are for the support of a child and that are not covered by paragraph 4 (i.e., those payments that either are not deductible to the payor or not taxable to the payee). These types of payments by a resident of a Contracting State to a resident of the other Contracting State are taxable in neither Contracting State.

Paragraph 6

Paragraph 6 deals with various aspects of cross-border pension contributions. There is no such rule in the OECD or U.N. Models, nor was there one in any of the previous U.S. Models. The 1992 OECD Model, however, deals extensively in the Commentary with this matter, providing both a model text and a discussion of the issues. Paragraph 6 has been included in this Model to ensure that certain differences between the two Contracting States' laws regarding pension contributions and pension plans will not inhibit the flow of personal services between the Contracting States.

Paragraph 6 essentially provides three types of benefits: deductions (or exclusions) at the employee and employer level for contributions to a pension plan (subparagraph (a)), exemption from tax on undistributed earnings realized by the plan (subparagraph (b)), and exemption from tax on rollovers from one plan to another (subparagraph (c)).

Subparagraph 6(a) allows for the deductibility (or excludability) in one State of contributions to a plan in the other State if certain conditions are satisfied. Subparagraph 6(a) also provides that contributions to the plan will be deductible for purposes of computing the employer's taxable income in the State where the individual renders services to the extent allowable in that State for contributions to plans established and recognized under that State's laws.

Where the United States is the host country, the exclusion of employee contributions from the employee’s income under this paragraph is limited to elective contributions not in excess of the amount specified in section 402(g). Deduction of employer contributions is subject to the limitations of sections 415 and 404. The section 404 limitation on deductions would be calculated as if the individual were the only employee covered by the plan.

Subparagraph 6(b) provides that income earned by the plan will not be taxable in the other State until the earnings are distributed.

Subparagraph 6(c) permits the individual to withdraw funds from the plan in the firstmentioned (home) State for the purpose of rolling over the amounts to a plan established in the other (host) Contracting State without being subjected to tax in the other State with respect to such amounts. This benefit is subject to any restrictions on rollovers under the laws of the other State. For instance, in the United States a rollover ordinarily must be made within 60 days of the withdrawal from the first plan under section 408(d)(3)(A)(i) and section 402(c). Rollovers from plans covered by Article 19 (Government Service) would not be covered by this provision. It is understood that, for the purposes of maintaining the tax-exempt status of a pension arrangement receiving rolled-over amounts, the assets received will be treated as assets rolled over from a qualified plan.

The benefits of this paragraph are allowed to an individual who is present in one of the Contracting States to perform either dependent or independent personal services. The individual, however, must be a visitor to the host country. Subparagraph 6(d) provides that the individual can receive the benefits of this paragraph only if he was contributing to the plan in his home country, or to a plan that was replaced by the plan to which he is contributing, before coming to the host country. The allowance of a successor plan would apply if, for example, the employer has been taken over by another corporation that replaces the existing plan with its own plan, rolling membership in the old plan over into the new plan.

In addition, the host-country competent authority must determine that the recognized plan to which a contribution is made in the home country of the individual generally corresponds to the plan in the host country. It is understood that United States plans eligible for the benefits of paragraph 6 include qualified plans under section 403(a), individual retirement plans (including individual retirement plans that are part of a simplified employee pension plan that satisfies section 408(k), IRAs and section 408(p) accounts), section 403(a) qualified annuity plans, individual retirement accounts, and section 403(b) plans. Finally, the benefits under this paragraph are limited to the benefits that the host country accords under its law, to the host country plan most similar to the home country plan, even if the home country would have

afforded greater benefits under its law. Thus, for example, if the host country has a cap on contributions equal to, say, five percent of the remuneration, and the home country has a seven percent cap, the deduction is limited to five percent, even though if the individual had remained in his home country he would have been allowed to take the larger deduction.

Relationship to Other Articles

Paragraphs 1, 3 and 4 of Article 18 are subject to the saving clause of paragraph 4 of Article 1 (General Scope). Thus, a U.S. citizen who is resident in the other Contracting State, and receives either a pension, annuity or alimony payment from the United States, may be subject to U.S. tax on the payment, notwithstanding the rules in those three paragraphs that give the State of residence of the recipient the exclusive taxing right. Paragraphs 2 and 5 are excepted from the saving clause by virtue of paragraph 5(a) of Article 1. Thus, the United States will allow U.S. citizens and residents the benefits of paragraph 5. Paragraph 6 is excepted from the saving clause with respect to permanent residents and citizens by virtue of paragraph 5(b) of Article 1.
