The Big 4 complication
Most planning frameworks assume an investor with reasonable freedom to construct a portfolio. Big 4 partners are not usually in that position.
Depending on firm, role and client exposure, the investable universe can be narrower than it looks: restrictions on direct shareholdings, certain funds, trading windows, disclosure obligations, pre-clearance requirements, sometimes mandated brokerage relationships. Concentration risk can emerge not because of what a partner chooses to hold, but because of what they are not permitted to hold. And the restrictions do not always end on the day partnership does — many firms maintain compliance obligations through a defined post-retirement period that affects when and how a portfolio can be reshaped.
Where a partner retirement allowance or firm-specific post-exit arrangement applies, it can be a meaningful part of post-exit income, but it depends on the firm covenant rather than personal assets, and the duration is usually fixed. Self-evidently it needs to be sequenced into the plan rather than treated as a permanent line of income.
Portfolio design therefore needs to be practical and compliant before it can be optimal — and that is a financial planning question more than a pure investment or pure tax efficiency one.
How much is enough?
The most common question is also the most deceptively simple. It cannot be answered properly by looking at the pension value alone. It needs a fuller view: expected spending, tax, inflation, healthcare, family support, property plans, the timing of firm-related payments and partner allowance income.
Some partners spend less after they disengage from the firm. Others spend more, particularly in the first few years if travel, family support or projects have been planned or deferred.
A good plan stress-tests more than one version of the future. What if markets fall early in retirement? What if inflation runs hotter for longer than expected? What if you or your partner needs care? What if children or grandchildren need real financial help, not just notional? What if exit happens sooner than planned?
For partners used to dealing in precision, that discomfort is the point and can be acute. Retirement planning is not about predicting the future accurately. It is about knowing what would have to go wrong before the plan becomes uncomfortable — and what you would do if it did. Good cash flow modelling is worth its weight in gold to secure “eyes-open” appreciation of the kind of scenarios you can realistically anticipate.
Planning is not prediction. It is knowing what would have to go wrong before the plan becomes uncomfortable — and what you would do if it did.
Pensions still matter — but the playbook has changed
For most partners, pension funding remains valuable, but the rules have shifted. The standard annual allowance is £60,000, although tapering can reduce this to £10,000 for those with sufficiently high adjusted and threshold income — a position many equity partners will need to calculate against actual figures, not assume. Up to three years of unused allowance can usually be carried forward. And where pension benefits have already been flexibly accessed, the money purchase annual allowance caps further money purchase contributions at £10,000 a year, regardless of carry-forward.
Many partners over 55 may also still hold transitional protection from the lifetime allowance era (fixed, individual, enhanced or primary) and these can affect the post-2024 Lump Sum Allowance and Lump Sum and Death Benefit Allowance regime in different ways. Reconciling that position before any plans are made to draw from pensions is essential.
The bigger shift is on the inheritance side. For deaths from 6 April 2027, most unused pension funds and pension death benefits will fall within the scope of inheritance tax (registered scheme death-in-service benefits remain excluded). That does not mean pensions stop being valuable. It does mean the long-standing habit of treating the pension as the last pot to touch may need to be revisited. Tax-free cash, drawdown timing, spousal provision, death benefit nominations, wills and lifetime gifting now belong in the same conversation, not separate ones. And taking an “all asset” approach to drawdown and estate planning strategy is even more important.
Replacing partnership income
Income will not come from one place — pension drawdown, ISAs, taxable portfolios, cash, property, partner retirement allowance, any continuing consultancy work — and the order matters. Drawing too much from the wrong place can result in avoidable tax and will be detrimental to capital preservation. Drawing too little from pensions can preserve wealth in the short term but build a larger estate problem in the long. Holding too much cash feels safe but exposes the plan to inflation; carrying more investment risk than needed exposes the plan to volatility it doesn’t need to take on.
Even partners with substantial wealth should check State Pension entitlement. The gov.uk forecast service shows expected entitlement and whether voluntary National Insurance contributions may improve it.
The human side
And then there is a part of the conversation that is easy to underplay: identity.
Partnership is not just a job. It can define status, purpose, routine, intellectual challenge and self-worth. For some, stepping away is liberating. For others, particularly where the timing feels firm-led rather than chosen, it can produce loss of control, anxiety or resentment.
Financial planning will not answer the emotional questions on its own. But it can restore agency. Knowing what is affordable, what is optional and what is resilient gives partners more room to think about the next stage on their own terms — whether that is non-executive work, philanthropy, mentoring, family time, a different rhythm, or simply the absence of pressure.
Where this leaves you and how we can help
Retirement from a Big 4 partnership is rarely a single decision. It is a process, shaped by timing, personal priorities and the need for confidence in the numbers.
Bringing pensions, investments, tax and firm specific considerations together can help turn uncertainty into clarity — and create a plan that is resilient as circumstances change.
We work with many Big 4 partners to bring together the financial, professional and personal elements of exit planning - helping you test options, understand trade-offs and retain control over timing.
