What is this strategy?
Pension Drawdown Bridge
Most UK retirees have a window between stopping work and receiving their State Pension. Using that window to draw your SIPP up to the personal allowance, or to take 25% tax-free cash via UFPLS, can save tens of thousands in tax. With pensions now in scope for Inheritance Tax from April 2027, controlled drawdown is also one of the most powerful tools for shaping your estate.
What pension drawdown actually means
Your SIPP isn't just a savings account. It's a future tax bill.
The Pension Drawdown Bridge strategy is focused on drawing your SIPP down in a way that minimises the tax hit over time. Left unmanaged, a large SIPP balance can push you into the higher-rate band the moment your State Pension starts, and from April 2027, what remains in the SIPP at death will count toward your estate for Inheritance Tax.
Optiml gives you the flexibility to choose your own drawdown pace. Pick a Conservative, Moderate, or Aggressive preset, or fully customise it by setting exactly when the drawdown starts and ends. Whatever you pick, Optiml builds the most tax-efficient withdrawal plan around it.
Throughout the drawdown, Optiml makes sure you still receive exactly the after-tax income you need each year. Your lifestyle is never sacrificed - the strategy simply restructures where the income comes from.
This is not about emptying your SIPP as fast as possible.
It is about drawing it down at the right pace, in the right years, to avoid a tax bill you could have planned around.
Want to go further? Consider the Maximise After-Tax Estate strategy.
Both strategies deliver the same after-tax income each year. The difference: the Pension Drawdown Bridge is focused solely on your SIPP, while the Maximise After-Tax Estate strategy factors in everything across SIPP, ISA, GIA, IHT, and beyond with one goal - ensuring your overall after-tax estate is as high as it can possibly be.
Choose your drawdown pace
Conservative
Gradual draw over a longer window, smaller annual withdrawals
Moderate
Balanced pace that keeps you in the basic-rate band
Aggressive
Faster draw to reduce future IHT exposure on the SIPP
Custom
You set exactly when it starts and when it is fully drawn down
Optiml builds the most tax-efficient drawdown plan around whichever pace you choose, while making sure your after-tax income is met every year.
No two plans are the same. Optiml's drawdown strategy depends entirely on your SIPP balance, income needs, age, and tax position. Never a template.
Under the Hood
A disciplined rule. Applied year by year.
This is a rule-based strategy, not an optimiser
Unlike the goal-based strategies, the Pension Drawdown Bridge does not iterate across thousands of possible plans searching for a single best outcome. It applies a structured, deterministic rule each year: calculate the right withdrawal for this year, execute it, and move to the next.
Each year Optiml calculates a withdrawal target using two complementary mechanisms. The actual withdrawal taken is whichever of the two produces the lower amount, ensuring the drawdown works correctly across all balance sizes while staying within the intended tax band.
Schedule draw
An annuity formula determines the annual gross withdrawal required to fully deplete the SIPP by the target age. Larger balances produce larger draws; smaller balances produce smaller ones.
Tax-band cap
Each year, Optiml selects an income-tax band boundary based on the strategy preset, personal allowance, basic-rate, or higher-rate. The cap ensures withdrawals never push income into a band the strategy is designed to avoid.
Annual withdrawal = min( schedule draw, tax-band cap )
Withdrawals are drawn from accounts in a fixed priority order: SIPP first, then GIA. Any surplus generated by the withdrawal, after meeting your after-tax income needs, is redirected into your ISA if subscription room is available, otherwise into your GIA, where it continues to grow.
For the Conservative, Moderate, and Aggressive presets, the drawdown begins the year you retire, typically the ideal window, when employment income has stopped but your State Pension and other guaranteed income sources may not have fully commenced, creating low-band room to draw the SIPP down efficiently.
Conservative
Target depletion
Age 85
Band target
Personal allowance only
Gradual draw over a longer runway with minimal annual tax impact. Suitable for those who want to reduce their SIPP slowly while staying inside the personal allowance.
Target depletion
Age 82
Band target
Basic-rate band
Balanced pace targeting the basic-rate ceiling. A good fit for most retirees with mid-sized SIPPs who want meaningful drawdown without higher-rate tax exposure.
Aggressive
Target depletion
Age 78
Band target
Up to higher-rate ceiling
Fastest depletion, reaching into the higher-rate band when it reduces IHT exposure. Best for large SIPPs where leaving the funds invested would cost more in IHT than withdrawing them costs in income tax.
Custom
Target depletion
Age User-defined
Band target
User-defined
Specify the start age and target depletion age independently. Optiml computes the schedule draw and tax-band cap using your chosen parameters.
Target depletion ages are a guideline, not a guarantee. The tax-band cap takes precedence each year. If depleting the SIPP by the target age would require withdrawals that push income into a higher band than the preset permits, those withdrawals are held back.
Lump Sum Allowance guard
The strategy tracks your remaining Lump Sum Allowance (£268,275) and will limit tax-free PCLS withdrawals so you do not breach the cap inadvertently.
Personal allowance taper guard
Withdrawal targets are managed so projected adjusted net income stays below the £100,000 personal allowance taper threshold whenever possible, preventing the 60% effective marginal band.
