The Tax Year Hangover: What Brits regret not doing before April 5th

Every year, just after the UK tax year ends on April 5, thousands of people are hit with a familiar feeling – regret. Despite the deadline being set in stone, millions rush to beat the clock. Whether that’s through rushed pension contributions, last-minute ISA transfers, or panicked investment reviews.

It’s no surprise the financial world calls it “Awful April”. But why does this happen year after year, and how can we break the cycle to avoid experiencing a tax year hangover?

Why regret sets in every April

There’s something deeply human about leaving important tasks until the last moment. But when it comes to financial planning, procrastination can have lasting consequences.

For many, the regret is twofold. First, there’s the pressure of making big decisions, like pension top-ups or ISA switches, without a clear long-term strategy. It becomes about beating the clock, not doing what’s best for your future.

Then comes the emotional toll. Financial planning should bring peace of mind and make you feel secure, but the last-minute scramble can lead to stress, second-guessing, and decision fatigue.

What people often miss

A key point many forget? If you don’t use your annual tax allowances before April 5th, they’re gone for good. That includes your ISA allowance, pension tax relief, and capital gains exemptions.

Also often overlooked is the importance of reviewing and rebalancing portfolios well ahead of the deadline. Planning should be proactive, not reactive.

Many may fixate on making last-minute contributions, but it’s worth remembering that tax efficiency isn’t just about saving money – it’s about maximising long-term opportunities. Missing an ISA or pension window doesn’t just lose a tax break, it’s a missed year of compounding growth.

A smarter way to plan

So, how do you avoid falling into the same trap next year?

  • Start early: April 6th should mark the beginning of your financial year. Get into the habit of tracking allowances, dividends, and investment performance from day one. It’ll make next year’s planning far easier.
  • Set it and forget it: Automate monthly contributions to ISAs and pensions throughout the year. It smooths out market ups and downs and saves you from making one big, stressful transfer in March.
  • Check-in mid-year: Don’t wait for March madness. Review your investments and check whether your asset allocation and risk exposure still align with your goals. Ideally, this should be done in Autumn – way ahead of the deadline.
  • Plan for July’s sting: For self-employed or higher-rate taxpayers, July 31st can deliver an unexpected financial blow. The second self-assessment payment often arrives just as attention shifts elsewhere, exposing gaps in cashflow planning. Acting early in the tax year helps ensure you’re firmly in control.
  • Learn from common mistakes: Every tax year leaves clues. Take note of what didn’t work this time and build your plan around avoiding those pitfalls next year.

A cultural shift in planning

As more people seek greater control over their financial futures, there’s a real opportunity to shift the narrative around the tax year. Rather than dreading April, we can learn to use it as a milestone, seeing it as a moment to celebrate progress, not panic.

Think of April 5 not as a deadline but the finish line of a long, well-paced race. Set your stride early, take care of obstacles, and cross the line feeling calm. After all, the best way to prevent a tax year hangover is to prepare like it’s already April – just 11 months early.
