Self Assessment for Additional Income Sources

What this service covers

You get practical support to report additional income correctly and avoid missed deadlines, overlooked allowances, or avoidable tax bills. Support can include:

• Reviewing all income sources that need declaring
• Working out what counts as taxable income and when it should be reported
• Calculating your tax and National Insurance position
• Identifying allowable expenses and reliefs you can legitimately claim
• Completing and submitting your Self Assessment return to HMRC
• Checking payments on account and helping you plan for what is due
• Answering questions in plain English so you understand the numbers

This is most useful if you have more than one income stream

This service is designed for people who are organised but time-poor, and want reassurance that everything is declared correctly. It is a good fit if you receive income alongside employment or your main business, for example from:

• Freelance or contracting work
• Rental income or property-related receipts
• Dividends or director income alongside PAYE
• Commission, referral fees, or online platform income
• Interest, gains, or other taxable one-off amounts

How the process works

First, you will get a clear list of what we need and by when. We then review your figures, highlight any gaps or risks, and confirm the approach before submission.

You will see draft calculations before anything is filed, so you know what you are paying and why. Once approved, the return is submitted and you receive confirmation plus a clear summary of the amounts and deadlines.

What happens after your return is filed

You will get a simple payment schedule and guidance on what to set aside going forward. If your additional income is likely to continue, we can suggest ways to keep records clean through the year so next time is faster and more predictable.
