UK Finances: Tax Year Changes, Bills & Money Q&A – Get Your Questions Answered

UK Financial Outlook: Interest Rates, Inflation, and Tax Changes in March 2026

From stubbornly high bills to uncertainty over interest rates, the pressure on household finances isn’t easing any time soon. The Bank of England has held rates at 3.75%, with global tensions – including the conflict in Iran – keeping inflation risks alive and delaying hoped-for cuts. For many, that means mortgages staying expensive and any real relief still feeling out of reach.

And just around the corner, another shift: the new tax year begins on 6 April.

That brings a raft of changes that could quietly reshape your finances. Dividend taxes are rising, the working from home allowance is being scrapped, and key thresholds and allowances remain tight.

For savers, it’s a last call to use this year’s ISA allowance before it resets – with future cash ISA limits set to shrink. At the same time, higher minimum wages will boost incomes for some, even as costs continue to climb elsewhere.

In short: a lot is changing, and not all of it is obvious.

Bank of England Holds Rates Amidst Iran Conflict

The Bank of England (BoE) has maintained its base interest rate at 3.75% following its latest meeting, a decision heavily influenced by the ongoing conflict in the Middle East and its impact on global energy prices. Prior to the escalation of tensions with Iran, economists widely anticipated a rate cut in March or April ¹. However, the disruption to oil and gas supplies has prompted a reassessment of that timeline.

Governor Andrew Bailey has stated the Bank “stands ready to act” on interest rates to control rising prices if the conflict persists ⁴. The BoE now expects inflation to be close to 3.5% in March, a higher figure than previously projected.

The Monetary Policy Committee (MPC) voted unanimously to hold rates, the first such decision in four-and-a-half years, to assess the evolving situation. While markets are anticipating potential rate increases later in the year, Bailey cautioned against assuming multiple rises ⁴.

Inflationary Pressures and the Iran War

The war in Iran has significantly impacted global energy markets, leading to increased oil and gas prices. This surge in energy costs is expected to keep UK inflation above 3% throughout 2026 ². The UK’s sensitivity to energy price fluctuations, coupled with already “sticky” inflation, has complicated the BoE’s monetary policy decisions.

Economists at JPMorgan have suggested that while BoE cuts are still possible in the first half of 2026, a March cut is off the table, and April requires a “clear calming of geopolitical tensions” ¹. They also acknowledge the increasing risk of a longer pause in rate cuts and a larger impact on economic growth.

Changes to Tax Year Beginning April 6th

Alongside the economic uncertainties, significant changes are coming with the new tax year on April 6th. These include:

• Dividend Taxes: An increase in dividend taxes will affect investors.
• Working From Home Allowance: The tax allowance for working from home is being removed.
• Tax Thresholds and Allowances: Key thresholds and allowances remain constrained.

ISA Allowance and Savings

Savers are encouraged to utilize their current ISA allowance before it resets. Future limits for cash ISAs are expected to decrease.

Minimum Wage Increases

Higher minimum wages will provide some financial relief for lower-income earners, while this will be offset by the broader increase in the cost of living.

Looking Ahead

The coming months present a complex financial landscape for UK households. The interplay between geopolitical events, inflation, and tax changes will require careful monitoring and proactive financial planning. The Bank of England will continue to assess the situation and adjust its monetary policy as needed to achieve its 2% inflation target ⁴.
