What is the most tax-efficient way to draw down my pension?

Reviewed by Tom Kimche, Head of Advice, Netwealth | [October 2026]

Taking money from your pension through drawdown gives you more control over your retirement income than almost any other retirement option. But that flexibility creates a real tax challenge. The taxable element of any withdrawal is added to your total income for the year and taxed at your marginal rate, while tax-free cash is subject to your available lump sum allowance. 

The decisions you make about when to draw, how much to take, and how to combine drawdown with other income sources determine how much of your pension pot you keep and how much you hand to HMRC.

Key takeaways

• Tax-free cash is normally limited to 25% of the benefits crystallised, subject to the lump sum allowance.
• Drawdown income above your tax-free cash is taxed at your marginal rate, so staying within the basic rate band means paying 20% rather than 40%.
• Taking taxable income flexibly normally triggers the MPAA, limiting future money purchase contributions to £10,000 a year, though taking only your tax-free lump sum doesn't.
• Pension drawdown funds currently sit outside your estate for IHT. 

Pension drawdown is one of the areas where the sequencing of decisions matters most. Netwealth's financial planners work with clients to model withdrawal scenarios year by year, balancing tax band management, tax-free cash timing, and estate planning.

What is pension drawdown and how does it work

Pension drawdown, formally called flexi-access drawdown, lets you move your pension savings into a drawdown fund and take money from your pension while the remaining funds stay invested. Unlike an annuity, which converts your pot into a guaranteed regular income for life, drawdown lets you withdraw as much or as little income as needed at any time.

Pension drawdown is flexible, but without careful management, withdrawals can deplete the pot faster than planned or push income into a higher tax band.

Defined contribution pension vs defined benefit pension

Flexi-access drawdown is only available from a defined contribution pension, where your retirement income depends on the value of your pension fund at retirement. Defined benefit pensions provide a guaranteed income for life and you can't move them directly into drawdown.

If you have a defined benefit pension and want drawdown flexibility, you'd need to transfer to a defined contribution arrangement. Always check your adviser is FCA-authorised before transferring a defined benefit pension, and consider all retirement options carefully first. High exit fees can apply on some older defined benefit schemes, so understanding the full risks involved matters before making any decision.

As an FCA-authorised discretionary wealth manager, we always recommend verifying your adviser’s authorisation before proceeding with any DB transfer. You can check the FCA register directly.

Pension fund: staying invested in drawdown

Your pension fund stays invested in the stock market and other assets while you draw income from it. The fund can continue to generate investment returns over a retirement lasting 20 to 30 years, but if markets fall significantly while you're drawing regular payments, the combination of falling values and continued withdrawals can deplete your pension fund faster than planned.

Pension drawdown tax rules: what you need to know

Pension drawdown tax rules are simple enough to understand but easy to get wrong in practice. HMRC treats the taxable element of drawdown withdrawals as pension income, adding it to all other income you receive in the same tax year, including state pension, rental income, and any employment earnings. Your total income determines your tax rate and how much you pay.

When do you pay tax on drawdown income

Any money taken from your pension drawdown beyond the initial 25% tax-free cash gets taxed as income. Withdrawals from a pension drawdown are taxed under the PAYE system, meaning your drawdown provider applies a tax deduction at source before the money from your pension reaches you, similar to how income tax is deducted from salaries.

The amount of income tax due depends on your available personal allowance, tax bands and other circumstances; the personal allowance is reduced where adjusted net income exceeds £100,000. The income tax rates for 2026/27 are:

How much tax will you pay on your pension

How much you pay depends on your total income in the tax year, not on any single pension withdrawal in isolation. Taking large withdrawals from a pension pot can push income into a higher tax band, resulting in a larger tax bill than anticipated.

The full new state pension is £241.30 per week, equalling £12,547.60 per year. That uses almost all of the personal allowance of £12,570. Any pension drawdown income in the same tax year on top of that is immediately taxable.

The same pension pot drawn over 15 years with careful band management produces more after-tax income than drawn over 5 years without a plan.

Our clients who model their drawdown year by year (rather than taking ad hoc withdrawals) typically find they keep meaningfully more of their pot over the course of a retirement. The difference compounds over time in a way that isn’t obvious until you run the numbers.

Emergency tax code on your first pension payment

When your drawdown provider makes your first flexible drawdown payment, they typically don't yet have a current tax code for you. They apply an emergency tax code, which deducts income tax as if the payment is your only income, grossed up to an annual rate. This can result in too much tax being deducted from the first payment. 

You can claim a tax refund directly from HM Revenue and Customs rather than waiting for the end of the tax year. Subsequent payments use the correct tax code once HMRC issues it.

In our experience, people are often caught off guard by the size of that first deduction; it can look alarming before you understand what’s happened. We can help clients understand how to reclaim overpaid emergency tax where appropriate.

 
The lump sum decision: taking only part at a time

You can usually access a defined contribution pension from the normal minimum pension age, currently 55 and rising to 57 from 6 April 2028, although some people have a protected pension age. 

Tax-free cash is normally up to 25% of the benefits crystallised and is subject to the standard lump sum allowance of £268,275 across all pensions. How you use it has a direct bearing on your total tax bill.

Taking the lump sum all at once vs in stages

Taking the full lump sum at retirement gives immediate access to a large tax-free sum. It also means moving the entire remaining 75% into the drawdown pot, where all future pension payments become fully taxable.

An alternative is phased drawdown: taking only part of the pension into drawdown at a time and taking only part of the 25% tax-free cash with each tranche. 

Drawdown provides the option to withdraw a combination of taxable income and tax-free cash, giving you more control over your tax position each year. This approach means:

• Each tranche releases a mix of tax-free cash and a taxable payment, giving you annual flexibility
• You control how much taxable income crystallises in any single tax year
• The death-benefit position depends on factors including the member's age at death, the scheme rules, the beneficiary and, from 6 April 2027, the revised inheritance tax treatment
• You preserve the tax-free cash benefit for future years when it may be most valuable

Managing drawdown pension tax within the basic rate band

A common tax-planning approach is to manage total taxable income within the basic-rate band where this is consistent with your wider needs and objectives. Income above £50,270 pushes into a higher tax band and attracts 40% tax, which rapidly erodes the value of your pension pot.

How much tax on total drawdown income each year

Say your state pension is £12,548 a year. Here's how two different drawdown amounts compare:

Drawing £40,000 pushes £2,278 of income above the £50,270 higher rate threshold. That slice alone is taxed at 40% instead of 20%, costing £911, double what it would have cost at the basic rate.

Keeping total annual income (including state pension, drawdown income, and other income) below £50,270 is the core discipline of tax-efficient drawdown. ISA withdrawals don't count toward this total, which is why combining pension drawdown with other savings is so powerful.

The money purchase annual allowance and when it is triggered

The money purchase annual allowance (MPAA) is one of the most consequential pension drawdown tax rules. The moment you access your pension pot flexibly by taking taxable income from a flexi-access drawdown fund, you trigger the MPAA. This permanently reduces your future pension annual allowance from £60,000 to just £10,000 per year. You can't carry unused MPAA forward.

Source: GOV.UK - Tax on your private pension contributions

Taking only the tax-free cash doesn't trigger the MPAA. Only taking taxable drawdown income activates it, and once you trigger it, you can't reverse it.

Breaching the MPAA results in a tax charge on contributions above £10,000. This matters most for anyone still working while drawing pension income, or for anyone who may return to employment later. Employer contributions within a workplace pension count toward the £10,000 limit.

The MPAA is one of the most commonly misunderstood rules in drawdown planning. Netwealth's advisers regularly work with clients who have already triggered it without realising, and with those who are still contributing to a pension and need to understand the implications before they take their first flexible withdrawal.

At Netwealth, our view is that getting clarity on your tax position before you begin drawing is far more valuable than trying to correct it afterwards.

Combining drawdown income with other savings and ISA income

The most tax-efficient retirement income strategy combines pension drawdown with ISA withdrawals and other savings, using each source for a different purpose. Pension drawdown provides taxable income managed within the basic rate band. ISA withdrawals top up income completely tax free without adding to your taxable total.

The ISA allowance is £20,000 per year and you can't carry it forward. A Netwealth ISA built up before retirement creates a tax-free income layer you can draw alongside your Netwealth pension drawdown without affecting your income band position.

Clients who arrive with both a pension pot and a meaningful ISA balance give us significantly more room to manage the annual tax position. The ISA means we’re not wholly dependent on pension drawdown to fund any given year’s income needs.

Withdrawing income from a pension can also impact your entitlement to means-tested state benefits like Universal Creditor and Pension Credit. If you're near the eligibility thresholds for either benefit, the timing and size of your pension drawdown income matters.

Pension drawdown and inheritance tax planning

Under the Finance Act 2026, most unused pension funds will be included in the value of a deceased person's estate for IHT purposes for deaths on or after 6 April 2027. Until that date, pension drawdown funds generally remain outside the estate. This affects how you sequence drawdown and which assets you preserve for beneficiaries.

This is the question we hear a lot from clients right now. For some, the April 2027 change may alter the balance between drawing from pensions and preserving other assets. The appropriate response will depend on income tax, inheritance tax, beneficiaries and wider objectives, so it should be modelled rather than assumed. 

Tax-efficient investing at this level means reviewing the whole picture every year: pension pot size, ISA balance, state pension timing, and how each year’s drawdown decision affects your tax code and total income.

Plan your pension drawdown strategy with Netwealth

Managing drawdown pension tax requires active decisions every year: how much to draw, from which source, whether to take more tax-free cash now or preserve it, and whether this year's income pushes you into a higher tax band.

Netwealth's financial planners build personalised retirement income plans around exactly these decisions, combining pension drawdown, ISA income, state pension timing, and estate planning. If you want to run the numbers first, our online planning tools let you model how different withdrawal scenarios play out across tax years before you speak to anyone.

Frequently Asked Questions

How does pension drawdown tax work?

All money you draw from your pension beyond the initial 25% tax-free cash adds to your total income in the same tax year. HMRC taxes it as pension income under PAYE and your drawdown provider applies a tax deduction at source. How much you pay depends on your total income from all sources that year.

What is the 25% tax-free lump sum allowance?

You can take up to 25% of your pension pot as a tax-free lump sum, capped at £268,275 across all your pensions, from age 55 (rising to 57 from 6 April 2028). You can take it as a single pension lump sum or in stages, giving you more control over your annual tax position.

What triggers the money purchase annual allowance?

Taking any taxable income from a flexi-access drawdown fund triggers the MPAA annual allowance, permanently limiting future defined contribution pension contributions to £10,000 per year. A tax charge applies if you exceed this. Taking only tax-free cash doesn't trigger it.

How do I avoid paying too much tax in drawdown?

Where appropriate, manage your total taxable income, including State Pension and taxable drawdown income, with reference to the £50,270 higher-rate threshold. Supplement pension drawdown with ISA withdrawals, which are tax free and don't count toward your income band. Check your tax code and refund position after your first pension payment to avoid carrying forward an overpayment.

When can I access my pension savings?

The normal minimum pension access age is currently 55 and rises to 57 from 6 April 2028 under the Finance Act 2022.

How does Netwealth help with pension drawdown planning?
