April 6th feels like a wall on the financial calendar. That's when the UK's tax year resets, and with it comes something brilliant: a clean slate for your tax allowances. Your ISA allowance refreshes to £20,000. Your Personal Savings Allowance resets. Your opportunity to earn without paying tax starts again from zero.
Most people see this date come and go without much thought. They don't switch banks, don't optimise their savings structure, and don't realise they've just left thousands of pounds of tax-free earning potential on the table.
But you're not most people. If you're reading this, you probably know that April isn't just a chance for a tidy desk and spring cleaning—it's a financial reset button. And if you combine bank switching, stoozing, and strategic savings account placement, you can turn this tax year into the most profitable one yet.
Let me walk you through exactly how.
Why April 6th Matters More Than You Think
The tax year running from April 6, 2023, to April 5, 2024, comes with three powerful tools:
Your £20,000 ISA allowance – This is tax-free money. Any interest earned within an ISA isn't taxed, regardless of the rate. You can split this across Stocks and Shares ISAs (investing), Cash ISAs (savings), Lifetime ISAs (saving for a home or retirement), or Innovative Finance ISAs (peer-to-peer lending). For most of us, cash ISAs are the practical winner right now.
Your Personal Savings Allowance – If you earn under £17,570, you get £1,000 of tax-free savings interest. For basic rate taxpayers (£17,570–£50,270), it's £500. Higher rate taxpayers (£50,270+) get just £0. This means basic rate taxpayers can earn up to £500 in interest without paying a penny in tax—but only if that money isn't sitting in an ISA-protected account.
Your 0% credit card spending window – Many 0% credit card offers reset for new applicants around this time. While you're managing tax allowances, you can also be earning interest on borrowed money. Yes, really.
The catch? These allowances are annual. You can't carry them forward. Use them or lose them.
Your April Money Reset Strategy
Step 1: Open a Cash ISA and Fill It (But Strategically)
Right now, your best bet is a competitive Cash ISA. Check our live offers page for current rates, but as of late April 2023, the market is offering somewhere between 4-5% on Cash ISAs for new switchers. That's genuinely good money.
Here's the play: if you have £20,000 spare, put it into a Cash ISA immediately. You've now created a pot of money earning interest completely tax-free for the whole year. On £20,000 at 4.5%, that's roughly £900 in your pocket, untouched by tax.
But wait—can you actually spare £20,000? Most people can't. So do this instead:
- Put whatever you can comfortably save into a Cash ISA (even £500 makes a difference).
- Use bank switching bonuses to earn the gap.
Step 2: Use Bank Switching to Fund Your Savings
Here's where April becomes a goldmine. Banks launch new switching offers constantly, and April—the start of the tax year—is prime time for promotions.
Right now, the offers on the table are solid:
- HSBC: £200 switching bonus
- NatWest: £200 switching bonus
- Santander: £200 switching bonus
- Halifax: £175 switching bonus
- First Direct: £175 switching bonus
If you're eligible and haven't switched in the last 3 years, you could pocket £175–£200 per switch. And here's the thing: most people can do 2-3 switches per year (the cooling-off checker period is 30 days, so after you complete a switch, you wait 30 days before switching again).
That means in April alone, you could earn £350–£600 in switching bonuses. Put this straight into your Cash ISA. Now you're boosting your tax-free pot without spending your own money.

Step 3: Top Up With Regular Saver Accounts
If you can set up a standing order from your main account, First Direct offers a 7% regular savers (as of April 2023)—though there are limits on monthly deposits. This is the kind of rate that makes your money work hard.
Regular savers typically cap monthly contributions at £200–£500, but that's fine. If you're putting aside £100 a month into a 7% saver, you'll earn roughly £70 over a year—completely tax-free if your total interest stays within your Personal Savings Allowance (£500 for basic rate taxpayers).
The beauty of regular savers is they're predictable. You know exactly what you're earning, and you know it's protected by your savings allowance.
Step 4: Consider Stoozing If You're Comfortable
Stoozing sounds exotic, but it's simple: you use a 0% credit card to earn interest on money in a savings account. You spend money on the card, immediately transfer that money to a savings account earning interest, and pay off the card in full before the 0% period ends.
Crude example: borrow £5,000 on a 0% credit card with a 20-month 0% period. Dump it in a savings account earning 4.5%. You earn roughly £375 in interest while paying absolutely nothing in fees or interest charges.
The risks are real (you must be disciplined, your credit score takes a hit), but so are the rewards. We've got a full guide at /how-it-works if you want to explore this further.
Your April Action Plan: Week by Week
Week 1 (immediately): Check your eligibility on our eligibility checker. Have you switched in the last 3 years? Do you have a valid UK address and clean credit file? If yes, you're good.
Week 2: Open a Cash ISA with the best rate you can find. Even if you don't fund it immediately, opening it now means any interest earned from April 6th onwards will be protected.
Week 3: Initiate your first bank switch. You'll have a new account within 7 working days. Once it's active, the 30-day cooling-off period starts counting.
Week 4: Once the bonus lands, transfer it into your ISA. Start thinking about your next switch (you can plan it for late May after the cooling-off period ends).
Throughout the month: Set up a regular saver if you can spare £100–£200 monthly. Even if it's just for 6 months, you're building tax-free interest.
Common Questions
Can I open multiple ISAs in the same tax year? Yes, you can hold multiple ISAs, but your total deposits across all ISAs cannot exceed £20,000 per tax year. So you could put £10,000 in a Cash ISA and £10,000 in a Stocks and Shares ISA, but not £15,000 in each.
Will bank switching damage my credit score? A hard credit search will appear on your file when you switch, which can temporarily lower your score by a few points. But it recovers quickly—usually within a few weeks. Multiple switches in short succession can look concerning to lenders, so space them out if you're planning to apply for a mortgage or loan soon. Read more about how switching affects your credit.
What if I don't have £20,000 to put in an ISA? No problem. Use whatever you can save, then boost it with switching bonuses and regular saver contributions. A £2,000 ISA earning 4.5% generates £90 a year, completely tax-free. That's real money.
Can I stooze if I have a poor credit history? It's harder but not impossible. Some 0% cards are available to people with less-than-perfect credit, though the credit limits tend to be smaller. Consider starting with bank switching (which is simpler and more reliable) and revisiting stoozing once you've rebuilt your score.
Is there a "best" way to combine all of this? Not universally—it depends on your comfort level and situation. The safest play is: open a Cash ISA, do 1–2 bank switches, funnel the bonuses and savings into your ISA. Add a regular saver if you can afford it. If you're confident and disciplined, layer stoozing on top for extra returns.
April's your reset. You've got a fresh ISA allowance, a Personal Savings Allowance that's full, and a marketplace full of bank switching offers. Banks are hungry for customers, best savings ratess are decent, and your tax-free earning potential is at its peak.
The question isn't whether you can make money this tax year. It's whether you'll take the time to set it up properly.
Start this week. Open that ISA. Check those offers. Your future self will thank you.
