In this step-by-step guide, we’ll walk you through everything you need to know to successfully file your HMRC self assessment. Let’s get started!
Step 1: Gather necessary documents
Before you dive into your self assessment, it’s essential to gather all the necessary documents. Having everything in one place will make the process smoother and ensure you don’t miss anything important. Here’s what you’ll need:
P60 and P45 forms: If you’ve changed jobs or been employed, these forms summarise your earnings and tax paid.
P11D or P9D: Details of any benefits or expenses.
Records of self-employment income and expenses: Keep track of your invoices, receipts, and expenses.
Bank and building society statements: These show your interest and income.
Dividend vouchers: If you own shares, you’ll need these to report dividends.
Pension contributions: Details of any contributions made to your pension.
Rental income: Records of any income from property rentals.
Other income sources: Any other income, such as savings interest, investments, or foreign income.
Step 2: Register for Self Assessment
If you’ve never filed a self assessment before, you’ll need to register with HMRC. Here’s how:
Go to the HMRC website and navigate to the self assessment registration page.
Fill in your personal details and submit the form. You’ll need your National Insurance number and details of your income.
Wait for your Unique Taxpayer Reference (UTR): HMRC will send you a UTR by post within 10 working days (21 days if you’re abroad).
Set up your online account: Once you have your UTR, you can set up your online account and get ready to file your return.
Step 3: Log In to Your HMRC Account
With your UTR and online account set up, it’s time to log in and get started on your self assessment:
Visit the HMRC website and click on the ‘Sign in’ button.
Enter your Government Gateway user ID and password.
Access your self assessment: Once logged in, select ‘Self Assessment’ from your account dashboard.
Step 4: Complete Your Tax Return
Now, you’re ready to fill out your tax return:
Start with your personal information: Confirm or update your personal details.
Enter your income details: This includes employment income, self-employment earnings, interest, dividends, and any other sources of income.
Claim any expenses and reliefs: Deductible expenses like travel, office supplies, and professional services should be listed here.
Review your tax calculation: HMRC’s system will automatically calculate your tax based on the information provided.
Step 5: Review and Submit
Before submitting, make sure everything is correct:
Double-check all entries: Ensure all income and expenses are accurately reported.
Look for common errors: Check for typos, incorrect figures, and any missed sections.
Submit your return: Once you’re confident everything is correct, submit your self assessment.
Save a copy for your records: Download and save a copy of your submitted return and the confirmation page.
Common Mistakes to Avoid
Even with the best intentions, mistakes can happen. Here are some common pitfalls to watch out for:
Missing the deadline: Ensure you file by January 31st to avoid penalties.
Incorrect figures: Double-check all your numbers to avoid errors.
Forgetting to claim expenses: Make sure you claim all allowable expenses to reduce your tax bill.
Not declaring all income: All income, no matter how small, must be declared.
Completing your HMRC self assessment doesn’t have to be stressful. By following these steps and avoiding common mistakes, you’ll be well on your way to filing your tax return accurately and on time. Remember, the key is to be organised and thorough.
