It's 1 March. The 2024/25 tax year ends on 5 April 2025.
That's 5 weeks to get organized, reduce your tax bill, and avoid last-minute panic.
Here's exactly what you need to do - whether you're a sole trader or company director.
Why This Matters
After 5 April 2025, you can't:
- Claim expenses for 2024/25
- Use this year's allowances (they don't carry forward)
- Make pension contributions that count for this year
- Reduce your 2024/25 tax bill
But right now, you still can. Let's make sure you don't leave money on the table.
For Sole Traders: What to Do Now
Week 1-2: Get Your Books Straight
Stop everything and update your records:
- Gather bank statements from 6 April 2024 to now
- Find all receipts and invoices
- Update your accounting software or spreadsheet
- Calculate your actual profit
You can't make smart decisions if you don't know where you stand.
Check Every Expense
Most sole traders forget to claim:
Home Office:
- £6/week (up to 25 hours) or £18/week (25-50 hours) or £26/week (50+ hours)
- Or calculate actual: portion of rent, utilities, council tax, internet
Mileage:
- 45p per mile (first 10,000 miles), then 25p
- NOT your commute
Equipment & Tech:
- Computer, software, phone (business portion)
- Office furniture, printer, stationery
Professional Costs:
- Accountant, memberships, training, insurance
Marketing:
- Website, domain, advertising, business cards
Go through your bank statements line by line. You'll find hundreds in forgotten expenses.
Week 3: Make Pension Contributions
This is huge for tax savings.
Example:
Profit: £40,000
Tax bill: £5,000
Put £5,000 in pension before 5 April:
- Costs you £4,000 (20% tax relief added automatically)
- Taxable income drops to £35,000
- Tax bill drops to £4,000
- You saved £1,000 in tax PLUS built your pension
Annual allowance: £60,000 (or 100% of earnings)
Deadline: 5 April 2025
Week 4: Buy Equipment Before Year-End
Planning to buy a laptop, van, or tools? Do it before 5 April.
Annual Investment Allowance: £1,000,000
Full tax relief this year. Buy it on 6 April? It counts for next year's tax return.
Week 5: Calculate What You Owe
Quick calculation:
1. Profit minus £12,570 (personal allowance) = Taxable profit
2. Tax: 20% on first £37,700, then 40%
3. Plus National Insurance: Class 2 (£179.40/year) + Class 4 (9% on profits)
Example:
£45,000 profit = approx. £9,584 total tax
Start saving now for your January 2026 payment.
For Company Directors: What to Do Now
Week 1-2: Review Salary vs Dividends
Check what you've taken in 2024/25:
- Salary taken so far?
- Dividends declared?
Optimal for 2024/25:
- Salary: £12,570 (or £9,100 if minimizing NI)
- Rest as dividends
Haven't used your full personal allowance? Take more salary or dividends before 5 April.
Week 3: Declare Final Dividends
Dividend allowance: £500 (tax-free)
Then: 8.75% (basic), 33.75% (higher), 39.35% (additional)
Important: Declare before 5 April (even if you don't pay out until later).
Must have:
- Board minutes
- Dividend voucher
- Proper accounting entry
Don't just transfer money. Do it properly or HMRC treats it as salary.
Make Company Pension Contributions
Your company can pay into your pension:
- Reduces company profits (less Corporation Tax)
- No personal Income Tax
- Counts as business expense
Example:
Company profit: £50,000
Corporation Tax (25%): £12,500
OR: Put £20,000 into pension before 5 April
Company profit: £30,000
Corporation Tax (19%): £5,700
Saved: £6,800 + £20,000 in your pension
Deadline: 5 April 2025
Week 4: Strategic Purchases
Company buying equipment?
Full Expensing/Annual Investment Allowance:
- Up to £1,000,000
- 100% deduction
- Immediate tax relief
Buy before 5 April = tax relief this year.
Week 5: Check Your Company Year-End
Your personal tax year (ends 5 April) is different from your company's accounting year-end.
Matters for timing salary and dividends. Work with your accountant on this.
Everyone Should Do This
Use Your ISA Allowance
£20,000 for 2024/25
Use it or lose it. Resets 6 April. Tax-free growth forever.
Capital Gains Allowance
£3,000 tax-free for 2024/25
Selling investments or property (not main home)? Consider doing it before 5 April to use this year's allowance.
Saves up to £560 in tax.
Making Tax Digital (MTD) - Check Your Compliance
If You're VAT-Registered (Already Mandatory):
Quick check - are you actually MTD compliant?
□ Using approved MTD software (Xero, Sage, QuickBooks)?
□ Records kept digitally in that software?
□ Submitting through the software (not HMRC website)?
If you answered "no" to any, you're not compliant. Sort this before your next VAT return.
Preparing for Income Tax MTD (April 2026):
If your income is over £50,000, from April 2026 you'll need:
- MTD-compatible software
- Quarterly digital updates to HMRC
- Digital record-keeping
That's 13 months away. Don't wait for the rush.
What to do now:
1. Check if your income will exceed £50,000
2. If yes, choose your software (Xero or Sage)
3. Start using it from 6 April 2025 (new tax year)
4. Get comfortable before it's mandatory

Common Year-End Mistakes
1. Waiting until January - Too late to do anything about 2024/25
2. No receipts - HMRC can disallow expenses without proof
3. Mixing personal and business - Accounting nightmare
4. Forgetting payments on account - January bill includes 50% advance for next year
5. Not getting help - Tax saved usually pays accountant fee many times over
