You get clarity on what you owe, confidence that your income and expenses are treated correctly, and fewer last-minute scrambles as deadlines approach. ## What this service covers This service is designed to keep Self Assessment simple, accurate and stress-free. Support typically includes: - Reviewing your income sources and confirming what needs to be declared - Organising and categorising allowable business expenses - Checking your records for gaps, duplicates, or personal items mixed in - Calculating your tax and National Insurance position before filing - Completing and submitting your Self Assessment tax return to HMRC - Explaining the result in plain English, including payment dates and what to set aside ### Who this is for This is a good fit if you are a sole trader, freelancer or contractor and you want the reassurance that your return is correct. It is especially helpful if you: - Have multiple clients or income streams - Are unsure what you can claim (use of home, travel, software, tools) - Have not kept tidy records during the year - Want an estimate of tax before the 31 January deadline ### How the process works 1. **Initial fact find**: confirm your income sources, expenses, and any changes (new work, property income, side income). 2. **Records check**: you provide bank statements, invoices, expense receipts or summaries. Any unclear items are queried. 3. **Draft position**: you receive a clear breakdown of profit, tax, and payments on account (where relevant). 4. **Filing and confirmation**: the return is submitted to HMRC and you get confirmation, plus payment guidance. ### After filing: staying in control Once filed, you will know what to pay and when, and what to keep aside going forward. If you want to avoid surprises next year, you can also put a simple record-keeping routine in place so your next return is faster and more accurate.

Many self-employed people need to file, but it depends on your income and circumstances. If you are unsure, we can confirm whether you need to register and file based on your situation. What information do you need from me? Usually your income totals (or invoices), business expenses, and bank statements for the tax year. If you have mileage logs, use-of-home costs, or other claims, share what you have and we will guide you on what is usable. Can you help me claim the right expenses without taking risks? Yes. We review your costs and apply HMRC rules so you claim what is allowable and can support it with records if asked. Where something is unclear, we will explain the options and the safest approach. When should I get started? As early as possible, especially if your records need tidying or you are not sure what you can claim. Starting early also helps you forecast what you will owe and plan your cash flow before the deadline. What if I have missed a deadline or need to catch up on past returns? You can often still file late returns and bring things up to date, but penalties and interest may apply. We can help you understand what is outstanding, prepare the returns, and agree a sensible plan to get compliant again.
