The Problem

Workers with incomes near critical tax thresholds (£50K, £60K, £80K, £100K in the UK, or similar brackets elsewhere) struggle to figure out the right pension contribution amounts to reduce their adjusted net income and retain valuable benefits like free childcare hours and child benefit. The interaction between salary sacrifice, AVCs, one-off income spikes (redundancy, share vestings, bonuses), and multiple overlapping benefit cliffs makes manual calculation error-prone and stressful, often leading to costly mistakes or missed deadlines.

Potential Solution

A web-based calculator and planning tool that ingests a user's salary, bonuses, share awards, and other income sources, then models multiple pension contribution scenarios against all relevant tax thresholds and benefit cliffs simultaneously. It shows the net financial impact of each scenario — including recovered child benefit, retained childcare hours, tax relief, and student loan savings — and recommends the optimal contribution amount, timing, and vehicle (SIPP, AVC, salary sacrifice) to maximize total household value.

Why Now?

Recent UK threshold changes to child benefit (raised to £60-80K in 2024) and the growing complexity of benefit tapers at £100K have created widespread confusion. Rising salaries and one-off corporate events are pushing more middle-income earners into unfamiliar tax territory, while the proliferation of pension vehicles (SIPP, AVC, CSAVC, salary sacrifice) makes DIY optimization increasingly difficult.

Tax saving via pension contribution for this financial year

Hello all I'm intending to make a (urgent, last minute!) deposit into my pension (as an AVC) to reduce some tax I've had to pay on savings interest (already being deducted from my salary by HMRC). It is a local government pension scheme. I'd also like to avoid paying back any child benefit, as I've partially exceeded the threshold. I was bereaved in early 2025 and received some money which temporarily increased my savings (now less as I paid off my mortgage when the very low fixed term deal ended in Dec). Income received this financial year: * Salary (gross): £54,495 * Savings interest: £7,700 * Pension benefit (death in service payment): £11,000 How much would people recommend I deposit into said pension as a lump sum? Is there a simple calculation based on current income tax thresholds? I’m 45 and realise I won’t be able to access until my late fifties (and will take at least 15 years to mature anyhow). I’m treating this as an exercise in investing money that otherwise has and will be taxed so I’m not looking to move a huge sum. Incidentally, I invest into a stocks and shares ISA and have maxed out this year’s contributions. Thanks all.

Childcare allowance & temporary income spike: how to stay under £100k?

Hi all, I’m looking for guidance around the **£100k adjusted net income threshold** and how it affects childcare benefits. This tax year is a bit of a mess income-wise due to a one-off combination of events: \- Employed by one company on a 98k/year salary until December \- Redundancy around Christmas (including a payment in lieu of holiday) \- Employer share awards vesting in February \[<- this is the main issue\] \- Surprisingly and luckily starting a new job with a similar salary in February As a result, my **headline income for the year looks very high**, even though: \- Some tax has already been withheld \- A significant portion of the income (essentially everything above the 100k threshold) is in shares rather than cash \- This is not a recurring situation The problem is that, unless action is taken, my **adjusted net income may exceed £100k**, which would mean losing eligibility for childcare support (free hours / tax-free childcare). That would have a major financial impact on our family, far outweighing the benefit of the extra income on paper. I’m trying to understand: \- What legitimate options exist to bring adjusted net income below £100k in a year like this (e.g. pensions/SIPP, carry-forward allowances, etc.), noting that the amount I'm over the threshold is significantly more than what the shares sell generate (due to being taxed at source) \- How realistic those options are when much of the income isn’t liquid without selling shares (and potentially triggering CGT) \- Any timing or reporting pitfalls that commonly catch people out with HMRC in situations like this \- How I could I return the childcare benefits I've received for this year BUT not lose them for next year when my income will be well under the 100k threshold. I’ll be speaking with a professional once final figures are available, but I’d really value: \- Experiences from others who’ve dealt with the £100k cliff due to one-off events, potentially where SIPP contribution were not a practical option \- Things you wish you’d known sooner \- Questions I should be asking an advisor Not looking for tailored advice, just trying to understand the landscape and avoid expensive mistakes. Thanks!

Help to understand civil service additional pensions via CSAVC

I am struggling to understand my CSAVC pension. So I arranged for the CSAVC which puts money into l&g for me to then pick a fund. I'm what I have noticed is there is no gov top up what I mean by this is that I put £100 into say pensionbee the pot would grow by £125. I assume this is maybe because I must be getting the savings from my PAYE tax, student loans and national insurance? I also have extra income which I need to self declare and pay taxes on. I might have wrongly put down this pension to bring my taxes down under being misinformed. Does anyone know much about CSAVC and if I have provided enough information?

Seeking advice on RRSP contribution to manage one-time high income year

I’m looking for some input on how to best manage a one-time spike in income following a corporate event. My company was sold earlier this year, and due to a CIC (Capital Investment Compensation) plan, my income for this year came in significantly higher than usual. My 2025 T4 shows total earnings of $679,400. Next year, my income will return to normal levels, approximately $181,000. I had originally planned to put $200,000 toward my mortgage to reduce my interest costs. However, after seeing my T4, I now realize I’m facing a significant tax liability—approximately $27,000—and I’m in a marginal tax bracket I’ve never been in before and likely will never be in again. To reduce my taxable income for the year, I’m considering making a roughly $50,000 contribution to my RRSP. (I'm currently at 150k deduction limit) While I understand that RRSP withdrawals are taxed upon retirement, my rationale is that this year’s income is a rare outlier, and contributing now could provide meaningful tax savings at today’s marginal rate. I’d appreciate any insights on whether this approach makes sense, or if there are other strategies I should consider in this situation. Thanks in advance.
