Tax-Deferred Annuity: How It Works, Types, Benefits and Risks for US Expats

For US expats and internationally mobile retirees, however, the US tax treatment is only part of the picture. An annuity’s suitability can also depend on your funding source, retirement horizon, liquidity requirements and how the contract is taxed in your country of residence.

This article explains what a tax-deferred annuity is, how it works and where it can fit within a retirement plan. It also covers the advantages and disadvantages of tax-deferred annuities and the additional tax and reporting considerations that can arise when you live outside the US.

What Is a Tax-Deferred Annuity?

A tax-deferred annuity is a financial contract with an insurance company that allows earnings to accumulate without being subject to current US federal income tax. As a result, interest or gains are generally not taxed annually while they remain inside the contract. Tax is typically triggered when withdrawals are made or when the contract is annuitised.

A tax-deferred annuity can be purchased with:

• One-off payment (single premium)
• Multiple payments (flexible)

If withdrawals occur during retirement, the holder may be in a lower marginal tax bracket than during their working years. Where this is the case, deferring tax until retirement can provide an additional tax-planning benefit. This outcome is not guaranteed, however, and for expats it will also depend on how the annuity is treated in their country of residence.

Most importantly, tax deferral does not eliminate tax liability; it postpones it until a future date.

How Does a Tax-Deferred Annuity Work?

A tax-deferred annuity operates in two distinct phases:

1. Accumulation phase
2. Payout (or distribution) phase

During the accumulation phase, you contribute to the annuity, and the contract grows through credited interest or investment returns on a tax-deferred basis. The payout phase begins when you start receiving withdrawals or annuitised payments.

At that point, previously deferred gains may become taxable as ordinary income for US federal income tax purposes. The exact treatment depends partly on whether the annuity is qualified or non-qualified and whether you take withdrawals or convert the contract into an income stream.

Some contracts allow structured withdrawals, while others can be converted into a stream of guaranteed payments.

Both phases should be considered when selecting an annuity, since decisions made during accumulation can affect tax, liquidity and income outcomes during retirement.

Qualified vs Non-Qualified Annuities

Annuities are also classified based on how they are funded, which affects the tax treatment of contributions and distributions:

1. Qualified annuities
2. Non-qualified annuities

For the purposes of this comparison, a qualified annuity is an annuity held within or funded through a tax-advantaged retirement arrangement, such as an Individual Retirement Account (IRA) or certain employer-sponsored retirement plans. Its contribution, distribution and Required Minimum Distribution rules generally depend on the underlying retirement arrangement.

A non-qualified annuity is purchased outside one of these arrangements using after-tax money.

The key distinctions are summarised below:

The distinction matters because placing an annuity inside a qualified retirement arrangement does not create an additional layer of tax deferral; the underlying retirement account already receives tax-advantaged treatment. The annuity may instead be used for other contract features, such as income guarantees.

For investors who have already used other tax-advantaged retirement options, a non-qualified annuity can provide another way to accumulate retirement assets without a traditional annual IRS contribution cap.

For US expats, however, the decision also needs to account for the tax treatment of the annuity in the country where they live.

How Tax-Deferred Growth Can Increase Compounding

One of the tax benefits of deferred annuities is that funds that might otherwise be used to pay annual tax on investment gains can remain within the contract.

This allows growth to come from:

In a taxable account, annual taxation of interest or gains can reduce the amount available for future compounding. Within a tax-deferred annuity, that capital remains in the contract until a taxable distribution occurs.

Over a long accumulation period, such as 15–20 years, retaining more capital within the contract can increase the amount available for compounding. Whether this produces a better after-tax outcome than another investment will depend on factors including fees, investment returns, the holding period and the tax treatment of distributions.

The eventual benefit also depends on:

• The length of the deferral period
• Investment performance or the contract’s credited rate
• Fees and charges
• Tax rates when distributions are taken
• Tax treatment in the investor’s country of residence

Tax deferral therefore affects the timing of taxation; it should not be confused with tax-free growth.

Tax-Deferred Annuity vs Immediate Annuity vs 403(b): What Is the Difference?

Tax-deferred annuities are often confused with other retirement vehicles and annuity structures, particularly immediate annuities and 403(b) plans. They can all form part of retirement planning, but they serve different purposes.

Tax-Deferred Annuity vs Immediate Annuity

An immediate annuity is also a contract with an insurance company that provides a stream of income. While the two products share this core structure, the primary distinction between a tax-deferred annuity and an immediate annuity is the payout timing:

• Tax-deferred annuity: Funds have an accumulation period before income or withdrawals commence. Depending on the contract, it can be bought with a lump sum or a series of payments.
• Immediate annuity: A lump sum is converted into income, with payments generally beginning within a relatively short period after purchase.

An immediate annuity may be relevant to someone who needs to convert capital into retirement income soon. A deferred annuity provides an accumulation period before payments begin, making the two structures suitable for different stages of retirement planning.

Tax-Deferred Annuity vs 403(b)

A 403(b) tax-sheltered annuity plan (TSA) is an employer-sponsored retirement plan available to eligible employees of public schools and certain tax-exempt organisations, as well as certain ministers.

Despite its name, a 403(b) is not simply another name for the standalone tax-deferred annuities discussed in this article. A 403(b) plan can hold different types of investments or arrangements, including:

• An annuity contract provided through an insurance company
• A custodial account invested in mutual funds
• Certain retirement income accounts for church employees

Employees can generally defer part of their salary into a 403(b), subject to applicable Internal Revenue Service (IRS) contribution limits. Employers may also make contributions.

Unlike a standalone non-qualified deferred annuity, a 403(b) is established through an eligible employer, and its contributions, investments and distributions are governed by the rules of the plan and the Internal Revenue Code.

The two are not necessarily mutually exclusive. An investor with a 403(b) may separately consider a non-qualified tax-deferred annuity as part of wider retirement planning, particularly after making use of other available tax-advantaged retirement accounts.

For someone who later moves abroad, both arrangements also need to be considered in the context of the tax rules that apply in their country of residence.

Types of Tax-Deferred Annuities

The main types of annuities to consider include:

1. Fixed annuities
2. Multi-year guaranteed annuities (MYGAs)
3. Variable annuities
4. Fixed indexed annuities

Fixed Annuities

A fixed deferred annuity credits a guaranteed interest rate set by the issuing insurer. It offers a high degree of predictability because the rate is guaranteed for a specified period under the terms of the contract.

After an initial guarantee period, the rate may reset, subject to any contractual minimum.

Since returns are not directly tied to market performance, growth potential may be lower than with market-linked investments, but the contract is also designed to provide greater predictability. A fixed deferred annuity may therefore be relevant to investors who place greater importance on contractual principal protection and predictable growth, subject to the terms of the contract and the claims-paying ability of the issuing insurer.

Multi-Year Guaranteed Annuities (MYGAs)

A multi-year guaranteed annuity (MYGA) is a type of fixed deferred annuity. After a lump sum is deposited, the insurer guarantees a fixed interest rate for a set term, often several years.

Unlike a traditional fixed annuity where the initial rate may apply for a shorter period before resetting, an MYGA fixes the credited rate for the selected guarantee term.

This can provide greater certainty for investors who are comfortable committing funds for a defined period. In return for that certainty, access to the capital may be restricted and withdrawals above any permitted amount can result in surrender charges.

The guarantee also depends on the claims-paying ability of the issuing insurance company.

Variable Annuities

A variable annuity invests premiums in sub-accounts that can hold market-based investments. Unlike fixed annuities, the contract’s value fluctuates with the performance of the underlying investments.

This gives variable annuities greater growth potential than fixed contracts, but the account value can also decline when investments perform poorly. Variable annuities can also carry several layers of fees.

Potential additional features include:

• Income rider: Can provide a contractual lifetime withdrawal benefit, subject to the terms of the rider.
• Death-benefit rider: Can provide beneficiaries with a specified minimum death benefit. Some contracts offer enhanced death benefits based on contract values or other formulas specified by the insurer.

Fees can materially affect long-term returns, so variable annuities need to be assessed in the context of the guarantees and insurance features being purchased rather than on tax deferral alone.

Fixed Indexed Annuities

A fixed indexed annuity credits interest by reference to the performance of a selected market index, such as the S&P 500.

You do not directly invest in the index. Instead, the insurer calculates interest using the method set out in the contract. Caps, participation rates, spreads and other crediting terms can limit the amount of an index gain that is credited.

The contract generally protects principal from direct losses caused solely by a fall in the reference index, subject to the insurer’s terms, withdrawals, applicable charges and the claims-paying ability of the issuing insurer. Some contracts also offer optional income riders for an additional fee.

Compared to fixed and variable annuities, fixed indexed annuities provide market-linked interest-crediting potential without direct investment in the underlying market index.

For investors living outside the US, product type is only one part of the decision. Availability can depend on your country of residence, while local tax treatment, insurer servicing restrictions and the treatment of guarantees or investment-linked returns may also affect whether a particular contract is suitable.

Tax-Deferred Annuity: Pros and Cons

Before committing funds to a tax-deferred annuity, it is important to consider its advantages and trade-offs against your retirement timeline, other retirement assets and liquidity needs.

Advantages of Tax-Deferred Annuities

Incorporating a tax-deferred annuity into your retirement strategy can offer the following advantages:

• Tax-deferred growth: Investment growth is generally not subject to annual US federal income tax while it remains within the contract. This leaves more capital available for compounding until distributions begin.
• No traditional contribution limits for non-qualified contracts: Non-qualified annuities are not subject to the annual IRS contribution limits that apply to IRAs and 401(k)s, although individual insurers can impose their own limits. They can therefore provide an additional tax-deferred savings vehicle for investors who have already made use of other retirement accounts.
• Optional guaranteed lifetime income: Depending on the contract, annuitisation or an optional income rider can provide payments for life. This can help address longevity risk, although guarantees depend on the contract and the claims-paying ability of the insurer.
• Potential probate-planning benefits: Where a valid beneficiary has been named, annuity proceeds may pass directly to the beneficiary rather than through probate, depending on the beneficiary designation and applicable estate and probate rules.

Disadvantages of Tax-Deferred Annuities

While a tax-deferred annuity can provide tax-deferred accumulation and retirement income options, it may not be the right retirement vehicle for everyone for several reasons:

• Potentially high fees: Fees vary by annuity type and can include mortality and expense charges, administrative fees, underlying investment expenses and optional rider fees. These costs can reduce long-term returns, particularly with more complex variable annuity contracts.
• Surrender charges: Withdrawals above any amount permitted under the contract can trigger surrender charges during the surrender period. This can restrict access to capital if your circumstances change.
• Inflation risk: Fixed income or returns may fail to keep pace with inflation over a long retirement. This can reduce the purchasing power of future income.
• Product complexity: Crediting methods, guarantees, caps, participation rates and rider structures vary between contracts. These differences can have a material effect on returns, liquidity and retirement income.
• Early withdrawal penalties: The taxable portion of certain distributions taken before age 59½ may be subject to an additional 10% US federal tax, unless an exception applies. Contractual surrender charges may also apply.

These trade-offs are particularly important for internationally mobile investors. A contract designed to be held for many years can become less practical if you later move country, need greater liquidity or find that your new country of residence applies different tax rules.

Tax-Deferred Annuities for US Expats

Tax deferral available under US federal tax rules does not necessarily determine how an annuity will be taxed in another country.

For US expats, this can change the economics of holding a tax-deferred annuity. Depending on local law:

• Annuity earnings may be taxed differently from their treatment in the US.
• A US annuity may be classified differently for local tax purposes.
• Withdrawals or annuity payments may be taxed under different rules.
• A tax treaty may affect which country has taxing rights over particular payments.

The position should therefore be considered in both the US and the country of residence. This becomes especially important before purchasing an annuity, taking a large distribution or moving between countries.

Foreign Annuities and PFIC Considerations

US persons considering a non-US-issued annuity also need to examine the structure and US tax treatment of the underlying arrangement.

A foreign-issued annuity should not automatically be treated as a Passive Foreign Investment Company (PFIC). PFIC exposure can arise where the structure and applicable US tax rules cause the holder to be treated as directly or indirectly owning interests in foreign corporations that meet the PFIC tests.

The contract structure and underlying investments therefore need to be analysed before concluding that the PFIC rules apply. Where they do apply, Form 8621 reporting and potentially unfavourable US tax treatment can arise.

For this reason, the US tax position of a foreign-issued annuity should be established before purchase rather than inferred from the way the product is described or taxed in its home jurisdiction.

FBAR and FATCA Reporting Obligations

US expats holding foreign financial assets may also have reporting obligations under FBAR and FATCA.

1. FBAR (Report of Foreign Bank and Financial Accounts): US persons generally need to file an FBAR if the aggregate value of their reportable foreign financial accounts exceeds $10,000 at any point during the calendar year. Foreign financial accounts can include annuity policies with a cash value and insurance policies with a cash value. FBAR is filed with the US Treasury’s Financial Crimes Enforcement Network (FinCEN), separately from the federal income tax return.
2. FATCA (Foreign Account Tax Compliance Act): Certain US taxpayers must report specified foreign financial assets on Form 8938 when the applicable thresholds are exceeded. Those thresholds vary according to factors including filing status and whether the taxpayer lives in the US or abroad. An interest in a foreign-issued annuity with a cash-surrender value can be a specified foreign financial asset for these purposes.

The reporting position depends on the contract and the holder’s circumstances, so ownership of a foreign annuity should be considered alongside other foreign accounts and financial assets.

Key Challenges of Coordinating Retirement Planning Across Multiple Tax Jurisdictions

US expats must also consider tax treaties between the US and their country of residence. The US has double tax agreements (DTAs) with a number of countries, including Spain, Portugal and the UK, which may affect how pension or annuity income is taxed and whether relief from double taxation is available.

Treaty provisions vary by country. The classification of a payment as pension income, an annuity, a lump sum or another form of income can also affect the outcome. US citizens may need to consider treaty provisions alongside the US rules that continue to apply to them as citizens, including any treaty saving clause.

Your cross-border retirement plan may therefore need to account for several practical issues:

• Some insurance companies decline new applications from non-US residents or restrict servicing once a policyholder relocates abroad.
• Committing a large share of savings to an annuity may be unsuitable for someone with uncertain relocation plans or significant future liquidity requirements.
• US annuity income paid in US dollars may need to be converted into local currency, creating exchange-rate exposure.
• Some insurers may impose restrictions on where distributions can be paid or on the services available after the policyholder moves abroad.

These factors make the investor’s current residence, likely future residence and intended withdrawal strategy important parts of the annuity decision.

What Should UK Residents With US Annuities Consider?

UK residents who hold US retirement assets need to consider both UK domestic tax rules and the US–UK double taxation agreement.

UK tax treatment can depend on the nature of the US arrangement. A foreign pension, an employment-related annuity and a personally purchased annuity can fall under different UK tax provisions. For example, a purchased life annuity from a non-UK insurer may have different UK treatment from a payment made from a US pension arrangement. The US name given to a contract does not, by itself, determine its UK tax treatment.

The US–UK treaty also contains separate provisions for pensions and similar remuneration, lump-sum payments derived from pension schemes and payments that meet the treaty’s definition of an annuity.

Under the treaty, an “annuity” for this purpose broadly involves a stated sum paid periodically at stated times during life or for a specified or ascertainable period, in return for adequate and full consideration other than services rendered. A US contract described commercially as an annuity will not necessarily fall within that treaty definition for every type of payment.

This makes the distinction between a pension arrangement and a personally purchased annuity important. It also makes the form of the distribution relevant: a regular payment, pension distribution and pension-scheme lump sum can fall under different treaty provisions.

US citizens living in the UK have an additional issue to consider. The treaty contains a saving clause, under which the US generally retains the right to tax its citizens under US domestic law except where a specific treaty exception applies. UK residence should therefore not be assumed, by itself, to remove US tax on a pension or annuity distribution.

For someone moving from the US to the UK, or already resident in the UK with a US annuity, relevant questions include:

• How is the contract classified under UK tax rules?
• Is it treated as a foreign pension, employment-related annuity or personally purchased annuity?
• Which provision of the US–UK treaty applies to the particular payment?
• Is the payment a periodic annuity payment, pension distribution or lump sum?
• How does the treaty’s saving clause affect a US citizen?
• Which country has taxing rights over the payment?
• Is relief available where the same income is exposed to tax in both countries?
• How will receiving income in US dollars affect retirement spending in sterling?

These questions are best addressed before taking significant withdrawals or making an irrevocable annuitisation decision.

Is a Deferred Annuity a Good Investment for US Expats?

Whether a deferred annuity is a good investment depends less on the tax deferral alone and more on what the contract is intended to achieve.

A tax-deferred annuity may be worth considering where you have a long enough investment horizon, do not need unrestricted access to the capital and value features such as predictable growth or future lifetime income.

It may be less suitable where liquidity is a priority, fees outweigh the value of the contract’s guarantees, or your future country of residence is uncertain.

For US expats, there is another question: will the tax and contractual advantages available in the US still work as intended after you move abroad?

That should be established alongside the product’s fees, surrender terms, income options and investment characteristics.
