1. Gather Your Documents Early
Before you even log into HMRC’s system, collect all the necessary documents. Having everything to hand saves time and avoids last-minute panic. This includes:
Your P60 or P45 (if applicable).
Bank interest statements.
Details of additional income (e.g., rental or freelance earnings).
Records of expenses and receipts (if self-employed).
2. Use the HMRC Online Checklist
HMRC provides a handy checklist for self-assessment. It’s a quick way to ensure you haven’t missed anything critical. Visit the HMRC website for their official guide.
3. Claim All Allowable Expenses
If you’re self-employed, make sure you claim all legitimate expenses. Every claim reduces your taxable income, potentially saving you hundreds. Common examples include:
Office supplies.
Business travel costs.
A proportion of home office expenses.
4. Check Your Tax Code
Ensure your tax code is correct, especially if you’ve changed jobs or income sources. An incorrect tax code could mean you’re paying too much tax.
5. Register for HMRC’s Online Services
If you haven’t already, register for HMRC’s online services. It can take up to 10 days to receive your activation code, so don’t delay. The online portal simplifies submission and provides helpful prompts.
6. Use Software or Apps
Self-assessment software, like QuickBooks or FreeAgent, can make calculations easier and reduce errors. Many apps integrate directly with HMRC’s system for seamless filing.
7. Set Aside Funds for Payment
If you owe tax, be prepared to pay it by 31st January. Setting aside funds throughout the year can prevent financial strain. Use HMRC’s tax calculator to estimate your liability.
8. Don’t Overlook the High Income Child Benefit Charge
If you or your partner claimed Child Benefit and your income exceeds £50,000, you may need to repay some or all of it through your tax return. HMRC’s online calculator can help you work out your liability.
9. Double-Check Your Entries
Mistakes can lead to fines or delays in processing. Double-check:
Your National Insurance number.
All figures entered.
Bank details for any refunds.
10. File Early to Avoid Stress
The closer you leave it to the deadline, the more likely you are to encounter system delays or errors. Filing early reduces stress and ensures you’re not rushing to beat the clock.
11. Seek Professional Help if Needed
If your finances are complex, it’s worth consulting a tax advisor. They can ensure accuracy, identify potential savings, and provide peace of mind.
12. Keep Records for the Future
Once you’ve submitted your return, store all related documents for at least five years. HMRC may request these during an audit.
