Tax-efficient withdrawal order in early retirement

A retirement plan that has accumulated enough to cover the target spending is only half-finished. The second half is the drawdown: which account to draw from, in what order, to minimise lifetime tax. This decision can easily affect the size of the final portfolio by 10-20% over a 30-year retirement, which is large enough to either extend retirement by several years or force a return to work.

It is also one of the most jurisdiction-specific decisions in retirement planning. The "right" order in the US is based on different tax mechanics than the right order in the UK or France, and applying a US-derived rule of thumb to a UK or French situation can produce outcomes that are both legal and badly suboptimal.

This post describes how the main drawdown orders work in each of the three jurisdictions covered by this cluster, what the trade-offs are, and what factors typically matter when someone is thinking through their own situation.

Important note before continuing: this is educational information about how three tax systems work. It is not personal financial advice. Individual circumstances — age, health, marital status, other income, inheritance intentions, state of residence, prospective moves — change the analysis materially. For decisions about your specific situation, consult a qualified financial adviser in your jurisdiction.

Why order matters

The basic reason order matters is that different accounts are taxed differently, both on the way in and on the way out.

Three account types recur across most developed-world retirement systems, with different names:

Tax-relieved-contribution accounts — pension-type accounts where contributions reduce taxable income now, but withdrawals are taxed as income later. UK SIPPs, US Traditional 401(k)/IRA, French PER (for deductible contributions).

Already-taxed-contribution accounts — accounts where contributions come from after-tax income, but withdrawals are tax-free. UK ISAs, US Roth IRAs, and — by construction of their withdrawal rules — French PEA after 5 years.

Taxable accounts — general investment accounts where contributions are not tax-relieved, and gains are taxed as realised. UK GIAs, US taxable brokerage, French assurance-vie (with favourable tax treatment after 8 years), general brokerage in any country.

In retirement, drawing from each account produces different tax outcomes per pound of spending. Drawing £10,000 from an ISA costs £10,000 of portfolio. Drawing £10,000 from a SIPP costs £10,000 of portfolio but also produces taxable income that may push the retiree into a higher tax bracket. Drawing £10,000 from a GIA costs £10,000 of portfolio and may produce a capital gain subject to CGT.

The order in which you draw affects not just the immediate tax bill but also the remaining balances across account types, which changes the tax situation of every subsequent year. Decisions compound. Bad decisions compound badly.

The UK picture

The UK system has three main vehicle types for most retirees: ISAs, SIPPs (or other pensions), and general investment accounts (GIAs). The tax mechanics are as follows.

ISA: No tax on withdrawals, no age restriction, no annual limit on how much can be withdrawn. Any gains or dividends inside the wrapper are tax-free.

SIPP: Accessible from age 55, rising to 57 in April 2028. 25% of the pot can typically be taken tax-free (the pension commencement lump sum, or PCLS), capped at £268,275 under the current lump sum allowance. The remaining 75% is taxed as income when drawn, potentially at 0%, 20%, 40%, or 45% depending on total income that year.

GIA: Gains above the annual CGT allowance (£3,000 in 2026/27) are taxable at 18% or 24% depending on the investor's income band. Dividends above the £500 allowance (2026/27) are taxed at 10.75%, 35.75%, or 39.35% depending on the same band. These dividend rates rose by two percentage points at the basic and higher bands from 6 April 2026; the additional rate remained unchanged.

Several common approaches exist. One is to draw first from the ISA, which has no tax cost but also uses up a valuable wrapper. Another is to draw from the SIPP up to the personal allowance (£12,570 in 2026/27), using the tax-free band that would otherwise go unused, then topping up with ISA withdrawals. Another is to manage the GIA drawdown to stay within the CGT and dividend allowances, preserving both ISA and SIPP as long as possible.

Each has trade-offs. Drawing the ISA first may feel tax-efficient but effectively converts tax-free space into future taxable withdrawals from the SIPP. Filling the personal allowance with SIPP withdrawals each year is tax-free income that reduces the total SIPP balance facing potentially higher tax later, but it depends on the retiree having other cash flow to cover actual spending. Drawing the GIA first uses the CGT and dividend allowances each year but depletes unwrapped savings first, which may matter for inheritance planning (GIA assets receive a CGT uplift on death under current rules; ISAs and SIPPs have different inheritance tax treatment).

The 25% tax-free lump sum deserves particular attention because the mechanical options are wide. The 25% can be taken all at once, phased across multiple years, or taken proportionally with each drawdown via flexible access drawdown (FAD) or uncrystallised funds pension lump sum (UFPLS) structures. Each option produces different lifetime tax outcomes depending on the retiree's income trajectory and marginal rates over time.

The French picture

The French system's main retirement-relevant wrappers are PER (Plan d'Épargne Retraite), assurance-vie, and PEA (Plan d'Épargne en Actions), with taxable brokerage outside these.

PER: Tax-relieved contributions in the deductible version; tax-relieved contributions produce taxable income on withdrawal. Early access is restricted to six specific cases (covered in the earlier post on the bridge problem), so for most retirees the PER becomes accessible at normal retirement age. Gains inside the wrapper face the 31.4% PFU on withdrawal for the primary-residence early-access case, with different treatment for the five accidents-de-la-vie cases.

Assurance-vie: A flexible taxable-but-efficient wrapper. After 8 years of holding, gains benefit from an annual allowance of €4,600 for a single person or €9,200 for a couple. Gains above the allowance are taxed at 7.5% income tax plus 17.2% social charges, for an effective rate of around 24.7%. No age restriction on withdrawals.

PEA: Tax-efficient equity wrapper. After 5 years, gains are exempt from French income tax on withdrawal (social charges of 18.6% from 2026 still apply). The cap on contributions is €150,000 per person, with additional room for PEA-PME and PEA Jeune variants. No age restriction on withdrawals after the 5-year mark.

Taxable brokerage: Standard 31.4% PFU (12.8% income tax + 18.6% social charges from 2026).

The mechanical considerations differ from the UK. The PEA, once past its 5-year mark, produces the lowest-tax withdrawals of any wrapper in the French system. Assurance-vie after 8 years is similarly efficient up to the annual allowance. The PER is the least-flexible vehicle and in many cases the most heavily taxed on withdrawal, depending on whether contributions were deducted.

Common approaches include drawing from the PEA first (since its tax treatment is most favourable), using assurance-vie up to the annual allowance each year (essentially capturing a €4,600/€9,200 tax-free bucket every year), and preserving the PER for traditional retirement age where it interacts with state pension income.

One French-specific consideration is the Prélèvements Forfaitaires Libératoires (PFL) option, which allows certain retirees to elect flat-rate taxation at source for specific income types. Whether this is beneficial depends on total income and marginal rates, and the answer is usually specific enough that professional advice is warranted.

The US picture

The US system has the most account types and the most specific sequencing considerations.

Taxable brokerage: Realised gains taxed at 0%, 15%, or 20% depending on income (long-term rate, held > 1 year). Dividends similarly taxed at qualified rates. Losses can offset gains.

Roth IRA / Roth 401(k): Tax-free withdrawals after 59½ (contributions can come out at any time tax- and penalty-free; earnings require both the 5-year rule and age 59½ for tax-free treatment).

Traditional IRA / 401(k): Withdrawals taxed as ordinary income. Required Minimum Distributions (RMDs) begin at age 73 under current rules.

HSA: Withdrawals tax-free for qualified medical expenses at any age. After age 65, withdrawals for any purpose are taxed as ordinary income (no penalty), making the HSA function as a Traditional-IRA-equivalent with bonus medical flexibility.

Social Security: Taxed federally depending on "combined income"; state taxation varies.

The US literature on withdrawal sequencing is unusually developed, partly because the tax interactions are more complex than in the UK or France. Three broad patterns appear repeatedly in the academic and practitioner literature.

Conventional wisdom ordering: taxable brokerage first, Traditional accounts second, Roth accounts last. The reasoning is that taxable accounts have already been partly taxed (cost basis is not taxed on withdrawal, only gains), so depleting them first while allowing the tax-advantaged accounts to compound longer produces a larger total after-tax portfolio over long horizons.

Tax-bracket-aware ordering: variations that draw from Traditional accounts each year up to the top of a chosen tax bracket (often 12% or 22% federal), then use Roth or taxable to top up actual spending. This manages marginal rates over a multi-decade retirement and tends to produce more total tax efficiency than rigid account-order rules.

Roth conversion ladders during low-income years: converting Traditional balances to Roth in years with low taxable income (particularly between retirement and Social Security/RMD start), paying ordinary income tax on the conversion but eliminating future RMDs and future income tax on the Roth balance. This approach interacts with Medicare IRMAA thresholds, ACA premium tax credits (before 65), and Social Security taxation, which is why it tends to require detailed modelling.

The HSA has specific treatment in most US drawdown analyses: because it retains tax-free status for medical expenses at any age, it is often preserved for late-stage medical spending (which tends to be high) rather than drawn early.

Cross-cutting considerations

Regardless of jurisdiction, several factors affect how the drawdown-order question is answered.

Longevity expectations. A retiree expecting to live into their 90s benefits more from preserving tax-advantaged compounding than one with a shorter horizon. Health status, family history, and personal circumstances matter.

Future tax rate expectations. If tax rates are expected to rise, paying tax now (e.g. by drawing Traditional/SIPP balances earlier, or doing Roth conversions) can be beneficial. If rates are expected to fall, the opposite. Predicting future tax rates over 30 years is difficult; the honest posture is uncertainty, which tends to favour diversification across account types rather than strong commitments to one direction.

Inheritance intentions. Different accounts have different inheritance treatments in every jurisdiction. UK pensions sit outside the estate for IHT in current rules; ISAs do not. US Roth accounts pass to heirs tax-free but face 10-year distribution rules under the SECURE Act. French assurance-vie has specific beneficiary-allowance rules (€152,500 per beneficiary before age 70). These differences mean that the "optimal" drawdown order for someone who intends to leave a bequest is often different from the optimal order for someone who does not.

Interaction with state/national pension income. UK state pension, US Social Security, and French state pension all start at specific ages and interact with other income in ways that affect marginal rates. Drawing heavily from taxed accounts in the years before state pension age may land in a lower tax bracket than drawing later, which is one reason the "bridge years" covered earlier in this cluster also tend to be the best Roth conversion years in US plans and the best personal-allowance-filling years in UK plans.

Spousal considerations. Married couples in all three jurisdictions have access to planning options that single retirees do not. Spousal ISA transfers on death, spousal pension inheritance, UK personal allowance transfers, French marital regime effects on assurance-vie, US filing-status choices — each of these can change the math of drawdown order substantially.

Mobility. A retiree planning to move jurisdictions during retirement (UK to Portugal, US to Mexico, France to Spain) faces additional complexity because withdrawal order that is efficient in one country may not be efficient in another. This is where cross-border advice becomes essential rather than optional.

What software can and cannot do

Drawdown order is one of the few areas in retirement planning where specialist software genuinely helps. The tax interactions are complex enough that manual analysis tends to miss edge cases, and the sensitivity to inputs (rates, longevity, inheritance intentions) is high enough that playing with different scenarios is more valuable than producing a single point answer.

What software can do: project multi-decade drawdowns under different account-order rules, calculate the after-tax lifetime portfolio under each, and surface the sensitivity to key assumptions. What software cannot do: know your health, your spouse's health, your children's financial situations, your intended charitable giving, your likely mobility, or your risk tolerance for policy change. These are the inputs that matter most, and they sit outside any calculator.

The honest role of software is to narrow the question rapidly so that professional advice can focus on the parts that matter. A retiree who walks into an adviser's office having already modelled the mechanical trade-offs of three different drawdown orders has a qualitatively better conversation than one who starts from scratch.

Where Endute fits

Endute's FIRE simulator models drawdown order at the account-type level for each supported jurisdiction. The output is not a recommendation — the tool does not produce one — but a comparison of likely lifetime tax outcomes under different drawdown approaches, with explicit handling of the jurisdiction-specific rules described in this post. This is useful for narrowing the question before taking professional advice, not a substitute for professional advice itself.

An important note on what this post is and is not

This post is educational information about how the UK, French, and US retirement tax systems work, written for readers who are thinking about how drawdown order affects after-tax outcomes in retirement. It describes common approaches used in each jurisdiction and the trade-offs involved. It is not a recommendation to use any particular approach, and it is not personal financial advice.

Withdrawal-order decisions interact with individual circumstances (age, marital status, health, other income, state of residence, inheritance intentions, future mobility, capital gains position of specific assets, and many others) in ways that a general article cannot account for. The "right" answer for a specific person can differ substantially from the general patterns described here.
