How are UK and Irish pensions taxed for Belgian residents from income year 2027 onward?
How are UK and Irish pensions taxed in Belgium? UK pensions may remain UK-taxable, while Irish pensions may be taxed in Belgium, depending on the plan.
A UK occupational pension first paid after 1 January 2013 is generally taxable only in the United Kingdom and exempt with progression in Belgium. An Irish occupational pension paid to a Belgian resident generally follows the opposite rule and is taxable in Belgium. The final treatment depends on the pension’s legal structure, contribution history, withdrawal method and the taxpayer’s other income.
The figures below are illustrative. The analysis is based on the rules and thresholds available in 2026, with potential payments beginning from income year 2027, assessment year 2028. All future-year thresholds must be verified before a withdrawal is made.
Why UK and Irish pensions follow different tax rules
Foreign pensions received by Belgian residents are not all taxed in the same way.
The decisive document is normally the double taxation convention between Belgium and the country in which the pension arises.
Under the amended Belgium–United Kingdom convention, certain pensions are taxed in the country of origin. Under the Belgium–Ireland convention, private-sector employment pensions are generally taxed in the country of residence.
This means that two foreign occupational pensions belonging to the same Belgian household may receive completely different tax treatment.
UK pensions first paid after 1 January 2013
Article 18 of the amended Belgium–United Kingdom convention provides that pensions and similar remuneration arising in one country and paid to a resident of the other country are generally taxable only in the country where the pension arises.
For a pension arising from a UK pension scheme, this normally gives the United Kingdom exclusive taxing rights.
A transitional rule applies to pensions that were already being paid before 1 January 2013. Those older pensions may continue to fall under the previous residence-state treatment.
For most workplace pensions that start paying after that date:
the pension is taxable in the United Kingdom;
it must still be reported in the Belgian tax return;
Belgium must normally grant a treaty exemption;
the exemption is generally applied with progression.
The same source-state principle may also apply to a UK State Pension that begins after 1 January 2013.
Belgian statutory, employee or public-sector pensions remain taxable in Belgium under the rules applicable to those pensions.
What exemption with progression means in Belgium
A UK pension that is treaty-exempt in Belgium is not necessarily irrelevant to the Belgian tax calculation.
Under the exemption with progression method, Belgium may take the exempt UK income into account when determining the tax rate applicable to the taxpayer’s other Belgian-taxable income.
For example, a substantial UK pension withdrawal could increase the effective Belgian tax rate applied to:
a Belgian statutory pension;
Belgian employment income;
replacement income;
other taxable pension income.
The Belgium–United Kingdom convention also allows Belgian municipalities to calculate a communal surcharge by reference to the theoretical Belgian tax on certain exempt income.
The municipal percentage varies by municipality and is frequently around 7%, although the actual percentage must be checked locally.
Consequently, “taxable only in the United Kingdom” does not always mean that the payment has no Belgian fiscal effect.
Is the UK 25% tax-free pension amount also exempt in Belgium?
Under UK pension rules, up to 25% of a pension pot may generally be taken as a Pension Commencement Lump Sum.
The source analysis refers to a lump sum allowance of £268,275. A pension below approximately £1.07 million would therefore usually remain within that ceiling, subject to the applicable UK rules and any previous lump sums.
The Belgium–United Kingdom convention defines income as being “taxed” in the United Kingdom where it is subjected to the tax system normally applicable to it under UK law.
The fact that the United Kingdom applies a domestic exemption to the permitted 25% portion should therefore not, by itself, transfer taxing rights to Belgium.
Provided that the pension continues to arise from a qualifying UK pension scheme and the post-2013 treaty rule applies, the tax-free UK portion should normally remain exempt in Belgium with progression.
The pension and treaty position should nevertheless be documented before the withdrawal.
Lump sum, flexi-access drawdown or annuity
Once the United Kingdom has exclusive taxing rights, the withdrawal decision is principally a UK tax-planning question.
Taking the whole pension in one year
After the permitted tax-free portion, the remaining pension is taxable as UK income in the year of withdrawal.
Taking the entire pension in one tax year can push a significant part of the payment into the UK 40% or 45% income tax bands.
This can make a full one-year withdrawal considerably more expensive than a staged drawdown.
Using flexi-access drawdown
With flexi-access drawdown, the taxable portion is withdrawn over several UK tax years.
The source analysis uses the following UK thresholds:
a £12,570 personal allowance;
a 20% basic rate on income up to £50,270.
These figures must be checked again for each future UK tax year.
By spreading withdrawals across several years and coordinating them with other UK-taxable income, it may be possible to keep a large part of the taxable pension within the personal allowance and basic-rate band.
For an illustrative pension pot of approximately £400,000 to £500,000, a structured withdrawal could produce:
approximately £100,000 to £125,000 as tax-free pension cash;
UK tax of roughly 13% to 15% on the taxable portion in a favourable multi-year scenario;
an indicative effective tax burden of approximately 10% to 12% across the total pot.
These percentages are not automatic. They depend on future tax bands, State Pension income, other UK income and the number of withdrawal years.
Purchasing an annuity
An annuity would also normally be taxable in the United Kingdom under the treaty.
However, an annuity:
converts the capital into a fixed or indexed income;
generally removes future withdrawal flexibility;
may leave limited or no capital for heirs;
does not create an obvious treaty advantage over drawdown.
The decision should therefore be based on income security, longevity protection, death benefits and the annuity quotation rather than on an assumed Belgian tax advantage.
Three UK pension mechanics to plan carefully
The minimum pension age
The normal minimum pension age rises from 55 to 57 on 6 April 2028, subject to any protected pension age that may apply to a particular scheme.
Anyone planning a withdrawal from 2028 onward should confirm the scheme’s exact access conditions.
The money purchase annual allowance
Once a person begins taking taxable flexible pension income, the money purchase annual allowance may restrict future tax-relieved contributions to £10,000 per year.
This can be highly disadvantageous for someone who is still making substantial workplace pension contributions.
Taking only the authorised tax-free pension cash does not normally trigger the allowance, but taking taxable flexible income generally does.
A common planning principle is therefore to complete the contribution phase before beginning taxable drawdown.
Emergency PAYE taxation
The first flexible taxable withdrawal is often subject to an emergency PAYE code.
The initial withholding may be higher than the final UK tax liability. The excess may be reclaimed through the appropriate HMRC procedure, including forms such as P55 or P53Z, depending on the circumstances.
Withdrawals should also be planned by reference to the UK tax year, which runs from 6 April to 5 April.
Why a QROPS transfer may increase the tax cost
A Qualifying Recognised Overseas Pension Scheme, or QROPS, is not automatically more tax-efficient for a Belgian resident.
Since 30 October 2024, the previous general exclusion for certain transfers to schemes in the European Economic Area or Gibraltar has been removed.
An Overseas Transfer Charge of 25% may therefore apply unless the individual is resident in the same country as the receiving pension scheme or another exemption applies.
Belgium does not have a widely used practical QROPS market. A transfer to a scheme established in another country, such as Malta or Gibraltar, could therefore create an immediate 25% charge.
A transfer outside the United Kingdom may also affect whether the pension continues to “arise” in the United Kingdom for treaty purposes. This could jeopardise the favourable UK source-state taxation.
Where different investment options or drawdown functions are needed, transferring between qualifying UK-registered pension schemes may be less disruptive than transferring the pension overseas.
How an Irish occupational pension is taxed
The Belgium–Ireland convention follows the more traditional pension rule.
A private-sector pension paid in consideration of past employment to a Belgian resident is generally taxable only in the country of residence, meaning Belgium.
Ireland should therefore provide treaty relief from Irish tax. Depending on the pension provider and payment method, this may require a treaty relief application or a PAYE Exclusion Order before the first payment.
The process should be arranged with the Irish pension provider and Irish Revenue in advance.
Does the Irish €200,000 tax-free lump sum apply in Belgium?
Irish domestic legislation may provide favourable treatment for retirement lump sums, including a tax-free amount of up to €200,000 under the Irish rules referred to in the source analysis.
That exemption does not automatically bind Belgium.
Where the treaty gives Belgium exclusive taxing rights, Belgium applies its own rules to determine:
whether the payment is pension income or pension capital;
whether it qualifies as supplementary occupational pension capital;
which part was employer-financed;
which part originated from personal contributions;
whether the payment is taxed separately or progressively.
A payment can therefore be tax-free in Ireland but taxable in Belgium.
Belgian taxation of foreign occupational pension capital
Historically, some foreign pension capital could escape Belgian taxation under the doctrine of individually and definitively vested rights.
The source analysis notes that the law of 21 January 2022 substantially restricted this approach where contributions generated a tax advantage in Belgium or abroad.
If contributions to an Irish occupational pension received Irish tax relief, Belgium may therefore tax the eventual capital.
The most important issue becomes the classification and applicable rate.
Where the scheme can be documented as a genuine employer-sponsored supplementary pension connected to employment, a one-off payment may potentially qualify for the Belgian separate rates applicable to second-pillar pension capital.
The source analysis identifies broadly:
16.5% to 20% on the employer-financed portion, depending on age and the circumstances of payment;
10% on qualifying personal contributions paid since 1993;
additional social or municipal charges where applicable.
These rates are not guaranteed merely because the foreign provider calls the arrangement a pension.
The Belgian classification should be supported by documents such as:
the scheme rules;
evidence of employer sponsorship;
the contribution history;
the split between employer and employee contributions;
proof of the foreign tax relief;
the conditions under which the capital becomes payable;
evidence that the plan’s purpose is retirement provision.
Without sufficient evidence, the Belgian administration could seek to tax the payment as ordinary pension income at progressive rates reaching 50%.
Capital payment or periodic Irish withdrawals
Periodic withdrawals from an Irish Approved Retirement Fund or a comparable arrangement may be treated in Belgium as recurring pension income.
That income would generally be taxed annually at the progressive Belgian rates.
A one-off capital payment may therefore be more favourable where the pension qualifies for the separate Belgian second-pillar rates.
Timing also matters.
Receiving the capital in a year with substantial salary or other taxable income could:
increase the impact of progressive taxation if separate taxation is refused;
affect reductions or tax calculations;
complicate the interaction with treaty-exempt employment income.
Where the pension terms allow flexibility, a payment after retirement and outside a year containing a full annual salary may provide a cleaner tax result.
A later payment age may also affect the separate rate, depending on the final Belgian classification.
Belgian group insurance capital
Belgian group insurance normally follows the domestic second-pillar pension regime.
The source analysis identifies the following deductions from the gross capital:
an INAMI contribution of 3.55%;
a solidarity contribution of up to 2%.
The remaining employer-financed capital may then be taxed at separate rates such as:
20% at age 60;
18% at age 61;
16.5% from age 62 or upon statutory retirement;
10% where the conditions for remaining effectively active until the legal retirement age are satisfied.
Personal contributions may be taxed at:
10% for qualifying contributions paid since 1993;
16.5% for qualifying contributions paid before 1993.
A communal surcharge may also apply.
The precise rate depends on the person’s age, retirement date, contribution history and whether the legal conditions for the 10% rate are fulfilled.
How to sequence UK, Irish and Belgian pension payments
Consider a typical Belgian-resident household with:
one UK occupational pension becoming accessible from around 2028;
one Irish occupational pension becoming payable from 2027 or later;
Belgian statutory pensions beginning in later years;
one or more Belgian group insurance capitals.
A possible sequencing framework would be:
Before the first Irish payment, collect the scheme rules, contribution records and evidence needed to support the Belgian occupational-pension classification.
Arrange the Irish treaty relief before the pension provider makes the payment.
Where appropriate, consider taking the Irish pension as a single capital payment in a year without a full annual employment salary.
Complete substantial UK pension contributions before taking any taxable flexi-access drawdown income.
Consider taking the authorised UK tax-free cash and staged taxable withdrawals during years in which Belgian-taxable income is relatively limited.
Use several UK tax years rather than one large withdrawal where this keeps more income within the UK personal allowance and basic-rate band.
Reassess the annual UK withdrawal when Belgian statutory pensions begin, because the exempt UK pension may increase the Belgian progression rate.
Consider that a future UK State Pension will use part of the UK personal allowance and basic-rate band.
This is a planning framework, not a universal withdrawal order. The optimal sequence depends on the pension contracts, future tax bands, exchange rates, retirement dates and household income.
Must foreign pension plans be reported during accumulation?
Belgian residents must report certain foreign assets, including:
foreign bank accounts, including notification to the National Bank of Belgium’s Central Point of Contact;
individually concluded foreign life insurance contracts.
A standard employer-sponsored occupational pension is not necessarily a foreign bank account or an individually concluded life insurance contract.
In many cases, no Belgian reporting obligation therefore arises while a genuine occupational pension remains in its accumulation phase.
However, the legal form must be checked.
Some UK workplace pensions are structured as group personal pensions, consisting legally of individual contracts. An Irish occupational arrangement may also use a structure requiring further analysis.
The provider’s commercial description is not enough. The contract and scheme rules determine the Belgian reporting treatment.
Where a reporting obligation is identified, a voluntary correction may be possible through the Belgian tax return and, where relevant, through MyMinfin. Whether penalties apply depends on the facts and the manner in which the correction is made.
Once pension payments begin:
UK pension payments must generally be declared in Belgium as treaty-exempt income with progression;
Irish pension payments must generally be declared as Belgian-taxable pension income or capital;
Belgian group insurance and statutory pension payments must be reported under the applicable domestic rules.
The main risks to avoid
The most significant risks in this type of cross-border retirement planning are:
transferring a UK pension to an overseas scheme without analysing the 25% Overseas Transfer Charge;
losing the favourable UK treaty connection through an inappropriate transfer;
taking the entire UK pension in one tax year;
triggering the £10,000 money purchase annual allowance while substantial contributions are still being made;
assuming that an Irish tax-free lump sum is also tax-free in Belgium;
taking periodic Irish pension income without comparing it with the Belgian taxation of a capital payment;
receiving the Irish payment before preparing evidence for the separate-rate classification;
failing to declare treaty-exempt UK payments in Belgium;
assuming that every workplace pension is exempt from Belgian foreign-contract reporting.
Frequently asked questions
Is a UK pension received by a Belgian resident taxed in Belgium?
A UK pension first paid after 1 January 2013 is generally taxable only in the United Kingdom under the amended treaty. It must nevertheless be declared in Belgium and may affect the tax rate on other income through exemption with progression.
Is the 25% UK pension lump sum tax-free in Belgium?
It should normally remain exempt in Belgium where it is the authorised tax-free portion of a post-2013 UK pension that continues to arise in the United Kingdom. The payment and the treaty position should be documented before withdrawal.
Does transferring a UK pension to a QROPS reduce Belgian tax?
Not necessarily. Since 30 October 2024, a transfer may trigger a 25% Overseas Transfer Charge, and moving the pension out of the United Kingdom may weaken the favourable treaty treatment.
Is an Irish pension lump sum of up to €200,000 tax-free for a Belgian resident?
Not automatically. The Irish domestic exemption does not determine the Belgian result where the treaty gives Belgium the right to tax the pension.
Is a foreign occupational pension capital always taxed at 10% or 16.5% in Belgium?
No. The separate rates depend on the pension’s legal classification, the financing source, the contribution dates, the payment circumstances and the available evidence. Otherwise, progressive taxation may apply.
Must a UK or Irish workplace pension be reported in Belgium before retirement?
A genuine employer-sponsored occupational scheme is often outside the reporting rules for foreign bank accounts and individually concluded life insurance contracts. However, group personal pensions and individually structured contracts require a specific legal-form review.
