You've got one week left. Seven days between now and April 5, when the tax year resets and your planning window slams shut. If you're unsure what matters and what doesn't, you're not alone—this final stretch is where most people either lock in genuine gains or accidentally leave money on the table.
The good news? You don't need to panic or rush into bad decisions. You just need a clear priority list and a realistic picture of what's actually urgent versus what can wait. Here's your exact playbook for the next week.
What Actually Needs to Happen This Week
Let's separate signal from noise. Some things are genuinely time-sensitive right now. Others aren't.
This week's actual hard deadlines:
If you're opening a new current account for a bank switch bonus, today is your practical last day. Most switches take 5-7 working days to settle, and you want the money credited by April 5 to ensure the bonus lands in this tax year. If you start the switch tomorrow (March 24), you're cutting it dangerously close—Easter weekend disrupts processing, and every working day matters.
If you haven't paid into a Regular Saver account yet this tax year and want to maximise it, check the deadline with your bank today. Most require deposits by March 31, and some close to new transactions earlier. If you're a new customer, some banks won't let you start mid-year, so verify this immediately.
If you're maxing out an ISA (Individual Savings Account) for tax-free interest, the deadline is genuinely April 5. However, if you're doing a large transfer between ISAs or moving money in and out of different types (Cash ISA vs Stocks and Shares ISA), start it now. Banks can take 3-5 working days to process ISA transfers, and you don't want to miss the window.
Stoozing isn't time-sensitive in the same way—0% periods run across the tax year boundary—but if you've got money sitting in a current account earning nothing, moving it to a 0% card today costs you nothing and gains you the interest. This is worth doing.
Everything else can wait.
Your tax return isn't due until 31 January 2027. Your records matter, but they don't need perfect organisation by April 6. Your mortgage application timeline hasn't changed because it's late March. Your credit score can recover after switches.
The Switching Question: Start or Stop?
This is the one people ask most. Should I initiate a bank switch now, or wait until April 6?
Start if:
- You've never switched with this bank before
- You can complete application and verification today (March 23)
- You're genuinely comfortable with the seven-day timeline
- The bonus is substantial enough to justify the minor timing risk
Wait if:
- You're unsure about application approval
- You've already got multiple switches settling this week
- You're worried about credit checks or verification delays
- The bonus is under £100 (really, wait—it's not worth the stress)
Here's the honest bit: you can switch after April 5 and it's fine. The bonus lands in the next tax year, sure, but the process isn't harder. What matters is that you're doing it at all, not which calendar page it lands on.
However, if you've been planning this specific switch for weeks and everything's ready, starting today gives you the best chance of credit landing this week. Just don't force it if you're uncertain.
Interest Timing: How to Capture Every Last Penny
Most current accounts pay interest once per month, usually on a specific date. Check yours: is it the 1st, the 15th, or the last day of the month?
If your account pays interest on March 31 or later, you're golden—it'll land this tax year regardless of what you do this week. If it paid on March 15, you've already captured it. If it pays on April 1, you've just caught the cutoff.
The practical move: if you're holding money in a low-paying account and you know interest pays in April, it's not worth moving it for three days. But if you've got cash sitting in a savings account earning 0.5% and you could move it to a 0% stoozing card or a higher-paying account earning 4%+, the arithmetic is simple—move it today.
Regular Savers: The Deadline Crunch
Regular Savers are usually your highest earners in percentage terms, but they're genuinely strict about deadlines. Most require:
- First deposit by March 31
- Monthly deposits on specific dates
- A stated account type (can't mix current and saver deposits)
If you haven't opened a Regular Saver yet and want to deposit for this tax year, do it today. Confirm the first-deposit deadline with your bank—some allow it until April 5, others close on March 31.
If you've got multiple Regular Savers, confirm you've actually deposited in each one this month. Banks don't auto-activate—you've got to manually transfer money, and they sometimes fail silently. Check your account confirmations now.
If you're planning to stack multiple Regular Savers next year and want to understand the returns properly, check our regular savers tool to model different combinations. This isn't urgent, but planning it this week sets you up perfectly for April 6.
ISA Final Moves: What You Actually Have Time For
You've got until April 5 to use this tax year's £20,000 ISA allowance. That's your limit before it resets. But logistics matter.
You can do this week:
- Transfer cash into a Cash ISA in your existing bank (instant or next day)
- Open a new ISA provider and deposit lump sums (takes 2-3 days)
- Move money between your own ISAs (usually 3-5 working days)
Don't try to do this week:
- Transfer ISAs between providers with existing balances (this is a formal "transfer"—takes 10-15 working days)
- Anything involving Stocks and Shares ISAs being moved or switched (the settlement time is too tight)
If you've got money sitting in a general savings account earning less than 4%, moving it to a Cash ISA earning 4%+ this week locks in the tax-free interest. It's worth doing if the gap is meaningful (£10,000 at 2% difference = £200/year tax-free).
Use our eligibility checker to confirm you're eligible for each ISA type—some have income limits or are only available to first-time buyers.
The Stoozing Reality: Is There Time?
If you've never stoozing before, this week is too late to start safely. You need:
- A 0% credit card application approved (2-3 working days)
- The card to arrive (2-5 working days)
- Time to move money in and confirm balances
Starting today means your card might not arrive until April 10. That's fine—just do it after April 5. Stoozing isn't tax-year-dependent in the way bonuses are.
If you've already got active 0% cards, today is the perfect day to review them:
- Check all your balance-transfer expiry dates (if you've got one expiring April 10, that's next week—plan the payoff)
- Calculate interest earned (0% means you're earning the savings account rate on this money)
- Verify your usage balance is accurate
Use the stoozing calculator to see what you're actually earning on your existing balances.
Credit Score: Stop Worrying
Opening a new current account or credit card does a hard credit check. Yes, it shows on your record. No, it doesn't tank your score long-term. Each hard check is a 5-10 point dip for 3-6 months, then it fades.
If you're applying for a mortgage in the next 6-12 months, don't start new switches now. The timing is too tight. If your mortgage application is April or later, you're fine—effects fade.
Use our eligibility checker to understand your borrowing profile before applying, so you're not surprised by rejections.
The Admin You Must Do This Week
Document everything. Your tax year ends April 5. Write down:
- Every bonus received and the date credited
- All interest earned month-by-month
- Every switch initiated (even if still settling)
- All 0% card balances and interest earned
- ISA deposits and transfers
This takes an hour and saves you chaos on tax return day. Seriously, do it today.
Verify your cooling-off periods. If you've switched banks in the last 6 months, you've got cooling-off windows that dictate when you can switch again. Use our cooling-off checker to confirm yours, so you're not surprised on April 6 when you can't switch to the next offer.
Check your old bank accounts. Any account you've closed in the last year—make sure you've got the closing balance and the final interest paid. This matters for tax purposes.
What You Can Safely Leave Until April 6
Everything else, frankly.
- Opening new accounts (you can do this first week of April)
- Researching next tax year's strategy (April is perfect for planning)
- Closing unused accounts (no rush—April 6 works fine)
- Starting fresh Regular Savers for next year (can start on April 6)
- Checking new bank offers (they update constantly—no advantage to checking today)
The psychological shift that helps: April 5 matters because it's a deadline, but it's not a cliff. You're not losing money after April 5. You're just moving your window into the next tax year, where the same strategies still work. Rushing destroys more value than waiting does.
Your Exact This-Week Checklist

- Today: Review all stoozing card expiry dates and plan payoffs
- Tomorrow (March 24): If you want to switch banks and haven't, initiate it now (latest safe start)
- By March 27: Document all tax-year earnings (bonuses, interest, transfers)
- By March 27: Use the cooling-off checker to confirm when you can switch next
- By April 5: Transfer any loose cash into your best-paying account (ISA or current account interest)
Common Questions
Can I still start a bank switch after April 5? Yes, completely. The switch process doesn't care about tax years. The bonus lands in the April 2026–2027 tax year instead of the March 2025–2026 year, but everything else is identical. No rush.
Will my 0% credit card balance expire across the tax year break? No. Your 0% period runs on calendar dates, not tax years. A card with a 24-month 0% doesn't suddenly stop working on April 5. Your balance carries straight over, and you keep earning interest until the 0% term ends.
Do I need to do anything with my ISA on April 5? No. Your ISA allowance resets automatically. Your existing balance stays, tax-free interest keeps accruing, and you're immediately eligible for the new £20,000 on April 6.
What if I miss a Regular Saver deadline? Check your provider's terms. Most allow you to restart in April with a fresh monthly cycle. You won't be penalised, but you'll miss the remaining months this tax year. That's okay—lock in next year instead.
Is the bonus I earn this week counted in this tax year? Yes. The date the bonus credits to your account is what matters. If it lands March 23–April 5, it counts as this tax year's income. After April 5, it's next year's.
