Canadian RRSP and UK Pension Planning for UK-Canada Movers

Canada and the United Kingdom share deep economic and cultural ties, and the movement of individuals between them is significant. For those who have built up retirement savings in both countries — a Registered Retirement Savings Plan (RRSP) in Canada and a UK pension — understanding how the two systems interact, where they diverge, and how to manage both effectively is essential to sound retirement planning.

This guide covers the key features of the RRSP system, the DTA framework, the transfer rules (or lack thereof), and practical planning for UK-Canada movers.

The UK-Canada Double Taxation Agreement: Article 18

The UK-Canada DTA was updated in 1978 and amended subsequently. Article 18 provides the framework for pension taxation between the two countries.

The general rule is that pension income is taxable in the country of residence at the time it is paid. A UK resident receiving Canadian pension income (including RRSP/RRIF distributions) should pay UK tax, not Canadian tax. A Canadian resident receiving UK pension income should pay Canadian tax on that income.

Government service pensions are generally taxable only in the country that pays them — so a former UK Civil Service employee living in Canada continues to pay UK tax on that pension.

The DTA also covers lump sum payments from pension schemes, which are treated as pension income for treaty purposes.

RRSP Withdrawals for Non-Residents: The 25% Withholding Issue

One of the most important practical features for non-resident Canadians is the non-resident withholding tax on RRSP withdrawals. Under Canadian domestic law, RRSP withdrawals by non-residents are subject to a 25% withholding tax.

The UK-Canada DTA reduces this withholding rate to 15% for periodic pension payments (regular instalments). However, lump sum withdrawals from an RRSP by a UK resident may still attract the higher 25% Canadian withholding tax unless the withdrawal is structured as a series of periodic payments.

The withholding tax is not a final liability — it is credited against the income tax due in the country of residence. A UK resident who has 15% or 25% withheld in Canada will report the RRSP distribution on their UK self-assessment return as foreign income and claim a foreign tax credit for the Canadian tax withheld. If the UK tax liability exceeds the credit, additional UK tax is due; if it is less, the excess Canadian withholding may be claimable as a refund from the CRA.

This creates cash flow implications, particularly for large lump sum RRSP withdrawals before the RRIF conversion deadline.

Mandatory RRIF Conversion at Age 71

An RRSP does not exist indefinitely. Under Canadian rules, an RRSP must be converted to a Registered Retirement Income Fund (RRIF) by December 31 of the year you turn 71 (or used to purchase a life annuity). Unlike the UK, where defined contribution pension funds can remain in drawdown indefinitely with no mandatory conversion, Canada requires the switch.

Once converted to an RRIF, a minimum annual withdrawal is required based on the fund balance and the account holder's age. The minimum withdrawal percentage increases each year from 5.28% at age 71 to 20% at age 95 and above. These withdrawals are taxable as income in Canada (or in the country of residence for non-residents, subject to withholding tax).

Non-resident Canadians living in the UK who hold RRSPs need to plan for this deadline. If you are a UK resident approaching age 71 with a Canadian RRSP, you must either convert it to a RRIF (triggering mandatory annual withdrawals subject to Canadian withholding tax) or collapse the RRSP as a lump sum (also subject to withholding tax). Neither can be avoided.

Cannot Transfer UK Pension to RRSP

Like US retirement accounts, Canadian RRSPs are not QROPS (Qualifying Recognised Overseas Pension Schemes). It is not possible to transfer a UK registered pension scheme into an RRSP. Any such transfer would be an unauthorised payment from the UK scheme and would trigger HMRC tax charges of up to 55% of the transferred value.

Similarly, there is no mechanism to transfer an RRSP into a UK SIPP or personal pension.

The two systems must be managed entirely separately throughout accumulation and into decumulation.

The Home Buyers' Plan: Early RRSP Access

The Home Buyers' Plan (HBP) is a Canadian government programme that allows RRSP holders to withdraw up to C$60,000 (raised from C$35,000 for withdrawals made after 16 April 2024) from their RRSP tax-free to purchase or build a qualifying first home in Canada. The withdrawal must be repaid to the RRSP over 15 years, with 1/15 of the amount due each year; missed repayments are treated as income. (For withdrawals between 1 January 2022 and 31 December 2025, the start of the repayment period is deferred to the fifth year after withdrawal.)

The HBP is available to first-time home buyers or individuals who have not owned a home in the previous four calendar years. For UK-Canada movers who hold an RRSP and are considering purchasing property in Canada, the HBP provides an important form of tax-deferred access to retirement savings.

Note that using the HBP reduces the RRSP's long-term compounding and repayments must be tracked carefully. The HBP is not available to non-residents of Canada.

RRSP vs UK Pension: Key Structural Differences

Feature	Canadian RRSP	UK Personal Pension / SIPP
Contribution type	Pre-tax (deducted from income)	Gross contribution (tax relief at source or net pay)
Annual contribution limit	18% of prior year earned income (max C$31,560 for 2024)	£60,000 (or 100% of earnings if lower)
Investment growth	Tax-deferred	Tax-free
Withdrawal taxation	Taxed as income	25% tax-free (up to Lump Sum Allowance), balance taxed as income
Mandatory conversion	RRIF by age 71	No mandatory conversion
Early access	Generally taxed + withheld at 25%	Minimum pension age (57 from 2028)
Employer contributions	Through Group RRSP or separate DPSP	Employer can contribute to workplace pension

The most significant practical difference is on the withdrawal side: a UK pension allows 25% of the fund (up to the Lump Sum Allowance of £268,275) to be taken tax-free, whereas an RRSP is fully taxable on withdrawal. This makes the RRSP a less tax-efficient vehicle at the point of decumulation for those who face high marginal tax rates.

TFSA vs ISA: The Tax-Free Savings Comparison

Both the UK and Canada offer tax-free savings wrappers outside of pensions:

Canadian TFSA (Tax-Free Savings Account): Contributions from post-tax income, growth and withdrawals entirely tax-free. The annual contribution limit for 2026 is C$7,000. Unused room carries forward. No income or capital gains tax on investments held within the wrapper. Withdrawals do not affect eligibility for income-tested benefits.

UK ISA: Contributions from post-tax income, growth and withdrawals entirely tax-free. Annual allowance is £20,000 per year. Stocks and Shares ISA, Cash ISA, and Innovative Finance ISA are the main variants. There is no carry-forward of unused ISA allowance.

Both function as tax-free wrappers on earnings and growth, and the conceptual comparison is straightforward. The key differences are:

• TFSA carries forward unused room — if you could not contribute in previous years, you can catch up. ISA allowances cannot be carried forward.
• TFSA withdrawal capacity is unlimited — you can withdraw from a TFSA and re-contribute in a later year without losing room (after the year of withdrawal). ISA withdrawals do not restore allowance unless it is a flexible ISA.
• ISA allowance is much larger in absolute terms (£20,000 vs approximately C$7,000).

For UK-Canada movers, holding both a TFSA and an ISA simultaneously may make sense — each is tax-free in its home country, but the UK resident holding a TFSA should seek advice on whether TFSA income is taxable in the UK (HMRC's position on foreign equivalent tax-free wrappers has not always been consistent).

Contributions While Mobile

UK pension contributions while in Canada: You need relevant UK earnings to make UK pension contributions above the £3,600 basic amount. If you are employed solely in Canada with no UK earnings, meaningful UK pension contributions are generally not possible. However, within five tax years of leaving the UK, you may contribute based on former UK earnings under the five-year rule if you were a UK resident with a UK pension before departure.

RRSP contributions while in the UK: RRSP contributions are based on Canadian earned income. If you have no Canadian income, you cannot generate new RRSP room. Existing RRSP balances remain invested in Canada and continue to grow tax-deferred (in Canada) regardless of your residence status.

State Pension Totalization

The UK and Canada have a Social Security Agreement (Totalization Agreement) which allows contribution periods in both countries' public pension systems to be combined to meet eligibility thresholds.

• UK State Pension requires a minimum of 10 qualifying National Insurance years to receive anything, and 35 years for the full New State Pension (£241.30/week for 2026/27).
• Canada Pension Plan (CPP) has its own contribution and benefit calculation rules, with no strict minimum — even one year of contributions generates a small benefit.
• Old Age Security (OAS) requires 10 years of residence in Canada after age 18 for non-residents, or 40 years for the full benefit.

If you do not have enough years in either system on its own, the Totalization Agreement may allow your periods to be combined to achieve eligibility — though each country pays only its own benefit, calculated on its own contribution record. It does not increase the amount paid by either country.

Compliance Caveat

This guide is for general informational purposes. Tax rules, DTA provisions, RRSP contribution limits, withholding tax rates, and pension regulations in both the UK and Canada are subject to change. Nothing in this guide constitutes financial or tax advice. You should seek advice from a professional with qualifications in both UK and Canadian tax before making pension transfer, contribution, or withdrawal decisions. The value of pension investments can fall as well as rise, and past performance is not a reliable indicator of future results.
