Retirement planning for high earners How to build a tax efficient retirement strategy…

Beating the 60% tax trap

As discussed, between £100,000 and £125,140, the withdrawal of the Personal Allowance can create an effective marginal income tax rate of approximately 60% for taxpayers paying the higher rate of income tax. This is because for every £2 earned above £100,000, £1 of personal allowance is lost.

This can be a problem but there are some potential fixes. In some circumstances, reducing your adjusted net income may help restore lost personal allowances:

• Pension contributions can reduce adjusted net income.
• Salary sacrifice arrangements may lower taxable earnings.
• Charitable donations under Gift Aid can also play a role.
• Careful bonus planning may help prevent income from drifting into the affected range.

However, pension contributions should be considered alongside annual allowance limits, carry forward, existing pension benefits and future retirement income requirements. It’s also important to consider these tactics not in isolation but rather as part of a broader financial plan.

Important to note that the below table only applies to England, Wales and Northern Ireland.

Managing annual and tapered allowances

When it comes to pension contributions, for many high earners the question changes from “how much should I save into my pension?” To “how much can I save into my pension while retaining the available tax advantages?”

As discussed, the pension annual allowance is currently £60,000. However, for higher earners, the tapered annual allowance can reduce this significantly. In some circumstances, individuals with threshold income above £200,000 and adjusted income above £260,000may see their allowance reduced to as little as £10,000.[3]

Understanding carry forward

There is a useful planning opportunity to help some higher earners with the tapered annual allowance. Carry forward rules may allow unused pension allowances from the previous three tax years to be utilised, subject to eligibility. For individuals who have experienced rapidly rising earnings or received significant bonuses, this can create substantial additional contribution capacity.[4]

For a high earner with fluctuating income, such as a business owner receiving an unusually large dividend or executive receiving a substantial bonus, this can be particularly valuable. However, for personal contributions, tax relief is generally limited to an individual’s relevant UK earnings in the tax year the contribution is made, and dividend income does not count towards this limit.

Before making a large contribution, it is important to calculate:

• Your available annual allowance for the current tax year.
• Whether the tapered annual allowance applies.
• Unused allowances from the previous three tax years.
• Contributions already made by you or your employer.
• Whether a contribution could affect other aspects of your tax position.

It is also worth mentioning that carry forward is only available where the individual was a member of a registered pension scheme during the relevant tax years. Any unused annual allowance available to carry forward must also take account of any tapered annual allowance that applied in those years.

Diversifying your retirement plan beyond pensions

Pensions aren’t the only tax efficient vehicle to consider. For high earners, particularly those affected by annual allowance restrictions, a diversified approach can provide greater flexibility over when and how wealth is accessed.

ISA and tax-free income streams

Individual Savings Accounts (ISAs) can complement pension saving by providing tax-free investment growth and withdrawals, subject to the relevant ISA rules.

Unlike pensions, ISA withdrawals do not generally count as taxable income. This can make ISA assets useful when constructing retirement income, particularly where managing taxable income is important.

It’s important to note that in the 2025 Autumn Budget some ISA rules were changed. From April 2027, the amount under 65s can invest in a cash ISA tax-free each tax year will be reduced to £12,000.[5] The overall ISA allowance still remains at £20,000 per tax year.

Someone using the full £12,000 cash ISA allowance could allocate the remaining £8,000 to other eligible ISA types.

Spousal distribution and dual allowances

Married couples and civil partners may benefit from structuring investments across both partners. This approach can make use of separate tax allowances, savings opportunities and investment capacities.

For example, investment income, dividends and realised capital gains may be taxed at different rates depending on which spouse owns the underlying assets. Each individual has their own £500 dividend allowance and £3,000 Capital Gains Tax annual exempt amount for 2026/27, while their wider income tax position can also affect the rate at which investment income is taxed.

Where appropriate, couples may therefore consider holding investments in both names rather than concentrating the entire portfolio in the higher earner’s name. Transfers of investments between spouses or civil partners who are living together are generally made on a no-gain, no-loss basis for Capital Gains Tax, allowing assets to be rearranged without an immediate CGT charge.[6]

The aim is not necessarily to split assets 50/50. The appropriate ownership can depend on each person’s income, existing investments, tax bands, pension position and future plans. This complexity is often why personalised advice is important.

Family Investment Companies (FICs)

A FIC is a private company used to hold investments on behalf of family members. It can allow parents or grandparents to separate control from ownership through different share classes, meaning they can retain decision-making authority while gradually passing wealth to future generations.

This structure can be particularly attractive for inheritance tax planning. In certain circumstances, future investment growth can be shifted outside of an individual’s estate while still allowing them to maintain oversight of how assets are managed and distributed.

FICs may hold a wide range of assets, including investment portfolios and property, and can be structured to support broader family wealth objectives over multiple generations.

However, FICs are incredibly sophisticated arrangements. They involve legal, tax and administrative responsibilities, and are generally most appropriate for families with substantial assets, often £2 million or more. Professional advice is essential to assess whether the potential benefits outweigh the complexity and costs involved.

Alternative tax-efficient structures

When pension and ISA allowances have been maximised, some investors might consider some additional options.

Offshore bonds are one alternative tax-efficient investment wrapper. They can offer flexibility over when taxable gains arise, however, their tax treatment can be complex and withdrawals, chargeable events and residency can all affect the outcome.

Another option is Venture Capital Trusts (VCTs) or Enterprise Investment Schemes (EIS). These can provide attractive tax incentives, but they come with significantly higher investment risks, limited liquidity and greater complexity. They should therefore be considered carefully and only where suitable.

Passing on wealth and supporting the next generation

For many high net worth individuals, retirement planning usually extends beyond just simple personal financial planning and security.

Children, grandchildren and future generations often form part of the discussion. You may want to help children or grandchildren with university costs, a first home or longer term financial security. But remember, it’s critical that decisions about passing on wealth need to be balanced against your own need for financial independence.

Some tax efficient ways to support family might include:

• Junior ISAs
• Pension contributions for children
• Education funding strategies
• Long term investment arrangements

Gifting and intergenerational wealth planning

Lifetime gifting can sometimes help reduce the value of your estate while allowing children and grandchildren to benefit from wealth sooner.

Useful strategies may include:

• Making gifts that fall outside your estate after seven years, provided you survive that period and other conditions are met.
• Using your annual gifting allowance and other available exemptions.
• Making regular gifts from surplus income, provided they do not affect your own standard of living.
• Funding Junior ISAs, pension contributions or education costs for younger family members.

However, gifting should be approached carefully. Certain gifts involving property, shares or investments can have tax implications, while giving away too much too soon could affect your own retirement security.

A reminder that the FCA does not regulate tax, trust or estate planning.

The role of cashflow modelling

Retirement planning isn’t just about accumulating wealth. It’s also about understanding how that wealth can support multiple goals over time.

Cashflow modelling uses sophisticated financial planning software to map your assets, liabilities, future income and expected expenditure against long term objectives. This helps answer questions such as:

• When can you realistically afford to retire?
• How much can you spend each year without jeopardising your future lifestyle?
• How much can you gift to children or grandchildren?
• What is the impact of retiring earlier, downsizing, or purchasing a second property?
• Will your wealth comfortably support future generations as well as your own retirement needs?

By modelling different scenarios and assumptions around inflation, investment returns and longevity, high earners can make more informed decisions with greater confidence.

The Financial Conduct Authority does not regulate cashflow modelling.

What does a ‘luxury’ retirement cost in the UK?

Defining a ‘luxury’ retirement is kind of like asking how long a piece of string is; it depends. According to the Retirement Living Standards, a comfortable retirement for an individual is £45,400 per year and for a couple £62,700 per year (for 2026/27).[7] It’s also important to remember that a high income doesn’t necessarily mean you need the same level of income in retirement.

For some, retirement expenditure may be significantly higher. Particularly when considering other factors such as international travel, property ownership, private healthcare or family support requirements.

Long term planning should account for:

• Inflation
• Investment returns
• Longevity
• Healthcare costs
• Desired lifestyle spending

Even substantial portfolios require careful management when expected to support decades of retirement income.

How does the 50-30-20 rule work for high earners?

The familiar 50-30-20 budgeting model suggests dividing after-tax income as follows[8]:

• 50% on needs
• 30% on wants
• 20% on savings

It can provide a useful starting point, but it is unlikely to be sufficient as a standalone strategy for someone with a high income and substantial assets. A high earner may already have significant pension savings, investments or property. Conversely, someone approaching retirement may need to save considerably more than 20% to achieve their desired future income.

Taking control

Often, the complexity of retirement planning increases when pensions, tax, investments and family wealth all interact. A bespoke approach can bring together:

• Pension contributions and annual allowance planning.
• Tax mitigation and income structuring.
• Investment strategy and asset allocation.
• Retirement income planning.
• Cashflow modelling.
• Estate and intergenerational planning.
• Business and personal wealth considerations.

The objective is not to find a single “best retirement plan for high income earners”. It is to construct a strategy that reflects your circumstances and remains adaptable as your income, assets, tax rules and priorities change. In this regard, a financial adviser can be incredibly helpful.
