What is this strategy?
Personal Allowance Taper Avoider
Between £100,000 and £125,140, you lose £1 of your personal allowance for every £2 of income, creating a brutal 60% effective marginal rate. The Personal Allowance Taper Avoider strategy structures your pension contributions, charitable giving, and withdrawal sequencing to keep adjusted net income below £100,000, restoring up to £12,570 of personal allowance and saving thousands every year you're in the band.
The Optimizer
Optiml does not follow an order. It tests everything.
There is no preset withdrawal order. Every possible combination of deposits and withdrawals is evaluated against your specific financial plan.
What the Taper Avoider actually means
One objective. Keep as much of your personal allowance as possible.
Like every Optiml strategy, the Personal Allowance Taper Avoider starts with your desired after-tax income each year and builds your plan around that. From there, its only focus is structuring your contributions and withdrawals so adjusted net income stays out of the £100,000–£125,140 band wherever possible.
Depending on your income, the strategy may eliminate the taper entirely, reduce it significantly, or confirm that your desired income simply puts you above £125,140 no matter what. In that case Optiml is honest with you upfront and points you toward a strategy that better fits your situation, like Maximise After-Tax Estate or Maximise Spending.
This strategy is not focused on your estate or lifetime taxes.
Its sole objective is to protect your personal allowance while delivering the after-tax income you need. If your income requirements are far above the taper ceiling, this strategy will tell you that clearly.

Every pound of allowance kept is a pound out of the 60% marginal band
No two plans are ever the same. The taper outcome depends entirely on your income sources, contributions, and how you draw your accounts each year. Never a template.
Under the Hood
Avoiding the taper is not about one rule. It is about the entire income picture.
Between £100,000 and £125,140 of adjusted net income, your £12,570 personal allowance reduces by £1 for every £2 of income, creating a brutal 60% effective marginal rate. Every income decision in your plan affects whether you fall into this band.
Optiml's non-linear optimisation engine maps every combination of withdrawals, deposits, pension contributions, and gift aid across your retirement years. Rather than applying a simple cap each year, it finds the plan that minimises the total tax cost of the taper across your entire plan, accounting for tax-band boundaries and Lump Sum Allowance simultaneously.
For households whose income would otherwise sit inside the band, Optiml may recommend additional pension contributions, charitable giving via gift aid, or salary sacrifice arrangements, each of which reduces adjusted net income and restores some or all of the lost personal allowance.
The objective
The optimiser minimises the total income lost to the personal allowance taper across all years:
Minimise: ∑ₜ TaperCost_t
TaperCost_t = 0.60 × min( max(0, ANI_t − £100,000), £25,140 )
ANI is your adjusted net income, which is taxable income minus gross pension contributions and gift aid grossed up.
Every path must satisfy one principal constraint
Your income from all sources, minus all taxes, living expenses, goals, and deposits, must net to exactly zero each year. No path is accepted that leaves you short of what you need to live.
Income − Taxes − Expenses − Goals − Deposits = 0
Worth knowing before you choose this strategy
Avoiding the taper and maximising your after-tax estate are not the same goal. By optimising purely for taper avoidance, the engine may favour withdrawal patterns that reduce what you leave behind. If a strong legacy matters to you, the Maximise After-Tax Estate strategy also accounts for the taper as part of its broader optimisation, and often delivers the same after-tax income with a larger estate.
The result is a precise, year-by-year plan: exactly how much to withdraw and contribute, in amounts that keep your adjusted net income below the taper threshold as often as mathematically possible, without ever compromising the after-tax income you need to live.
