Budget Day Is 28 October: What's Already Announced, What's Only Rumour, and What to Do With Your ISA and Pension Until Then

The FCA's retirement income data, published on 24 September, shows that 64.5% of people who moved into drawdown in 2025/26 took a tax-free lump sum, up from 61.9% the year before. AJ Bell, which analysed the same figures, puts the total tax-free cash withdrawn at £22 billion, more than two and a half times the £7.9 billion a year that was normal in the five years to 2022/23, and it blames Budget uncertainty for the surge. Then the November 2025 Budget arrived and left the 25% tax-free lump sum exactly where it was, as MoneyHelper confirmed on the day. Anyone who took the money early because of a headline and parked it in a savings account gave up tax-free growth inside the pension and, once any personal savings allowance was used up, started paying tax on the interest as well. That is what a rumour costs when you act on it: it is rarely the rumour itself that does the damage, it is the irreversible move you made in response. The next Budget is on Wednesday 28 October, confirmed in the Chancellor's letter to the Treasury Select Committee on 31 July, which leaves 24 days of speculation starting today.

What the Treasury Has Already Told You

Start with the part that isn't speculation, because it is easily mistaken for it. Four changes are already announced and written up on GOV.UK, and each one has a date attached.

• From 6 April 2027, the cash ISA limit for under-65s falls to £12,000 inside the unchanged £20,000 overall ISA allowance, while savers aged 65 and over keep a £20,000 cash limit.
• The anti-circumvention rules announced on 23 June 2026 add a flat 22% charge on interest paid on cash held inside Stocks & Shares ISAs, restrictions on moving money from a Stocks & Shares ISA into a cash ISA, and new rules for money market funds.
• Also from 6 April 2027, most unused pension funds and death benefits come within the scope of inheritance tax, with death-in-service benefits excluded.
• From April 2029, the National Insurance exemption on employee pension contributions made through salary sacrifice is capped at £2,000 a year.

Look at the spread of dates rather than the contents. The cash ISA change lands about 16 months after the Budget that announced it, and the salary sacrifice cap more than three years after, so most of what you will hear on the 28th will give you time to adjust. Not all of it, though. The capital gains tax rise announced on 30 October 2024 (from 10% and 20% to 18% and 24% on most assets) applied to disposals made on or after that same day, with special provisions for contracts already entered into before it. A Budget can change your tax within hours or leave you years to prepare, and a rumour tells you nothing about which kind you are dealing with.

What Is Still Only Rumour

Nothing in this section is confirmed, and nothing will be until Budget day itself.

Which? reports that the Prime Minister has said the personal allowance will be reviewed at this Budget while declining to commit to a change, and that a senior government figure argued in an essay earlier this year for pulling capital gains tax closer to income tax bands and for ending the uplift at death, the rule that wipes out the gain on shares when they are inherited. Hargreaves Lansdown's recent Budget commentary mentions CGT rates as high as 45% for the highest earners in the speculation, plus a recurring rumour about pension tax relief. None of this has been confirmed by the Treasury, which is exactly why none of it is a reason to move money. A rumour with no mechanism and no start date can't be priced, and a decision you can't price is a guess with a tax bill attached.

Does that make the rumour mill always wrong? No, and 2024 is the awkward counter-example. Before that Budget, fears that CGT would be aligned with income tax rates led a modest number of Hargreaves Lansdown clients to realise gains early, by the firm's own account. What arrived was smaller than full alignment but still a rise, and it took effect that day, so a man who sold a holding in a general investment account in the week before 30 October 2024 paid 10% or 20% on a gain that would have cost 18% or 24% a week later. The saving was real, somewhere between four and eight percentage points of the gain, but it only paid off for the man who was already happy to sell. The one who sold a fund he wanted to keep brought forward a tax bill that could have waited indefinitely, and if rates had stayed put he would have paid it for nothing.

A Three-Question Filter for Every Pre-Budget Impulse

Before you move money because of something you read this month, put the idea through three questions.

1. Would I do this on 29 October anyway?
2. If the rumour turns out to be nothing, can I undo the move, or am I stuck with it?
3. Does the rumour come with a named source and a stated mechanism, or only a headline?

Now run the usual suspects through it. Taking your tax-free cash early fails the first two questions, and the answer is simple: leave it where it is. The lump sum allowance is £268,275, you can normally take it from 55 (57 from April 2028), and it will still be there when you have an actual use for the money. The one exception is a man whose plans changed because pensions fall into the estate from April 2027 and who now wants to draw on pension money before ISA money. That is a plan rather than a reaction, but it deserves a proper model and ideally an adviser, not a decision made in the week of a Budget.

Topping up your SIPP passes question one only if you were already planning to. The annual allowance is £60,000, tax relief is limited to 100% of your earnings, and unused allowance from the three previous tax years can be carried forward. Paying in during October rather than March makes no difference to the tax relief, but the money is locked until 55 (57 from April 2028), so size the contribution by what you can live without for two decades, not by what you fear. Selling winners to beat a CGT rise fails question one for most people. The exception is a tidy-up you would do anyway: selling inside the £3,000 annual exempt amount and rebuying the same holdings inside your £20,000 ISA allowance, the Bed and ISA routine, costs little beyond dealing fees (plus stamp duty on UK shares), and it shelters every future gain whether or not rates rise. If you hold investments outside a wrapper and still have ISA allowance left, that is the one pre-Budget move worth making.

Two Dates Eight Days Apart

The Budget is on 28 October. Eight days later, on 5 November, the Bank of England's Monetary Policy Committee publishes its next decision. In September it held Bank Rate at 3.75% by six votes to three, with the three dissenters voting for a rise to 4%, and it reported that UK CPI inflation had risen to 3.1% in August, with energy prices accounting for around 0.7 percentage points of the 1.1-point overshoot against the 2% target. Two announcements that can move gilts, sterling and share prices inside eight days make a poor window to rebalance because you feel uneasy, and a perfectly good one to rebalance on a date you chose in advance. If a rebalance is due, put it in the diary for a day that is not the 28th, not the 5th, and not the morning after either.

What to Read on Budget Day

When the changes land, the headline is the least useful part of the coverage. Check three things in the Treasury's own papers: the effective date, who the change applies to, and whether any special provision catches what you did in the weeks before. The cash ISA reduction shows why the second one matters, because a £12,000 limit sounds universal until you reach the over-65s carve-out. The 2024 CGT policy note shows the third, with its provisions for contracts entered into before 30 October 2024 but completed after it, the kind of detail you only find in the note rather than the summary.

So spend today on one small job: write down the single decision you would make differently if one particular rumour came true. If you can't name one, your plan is the plan until the 28th, and the only thing that needs a note in the diary is the date.

General information, not personal financial advice. Figures and rules are as published on GOV.UK, the FCA and the Bank of England on 4 October 2026 and may change on Budget day.
