Our service includes a full review of your income and expenses, preparation of your SA100, calculation of your tax liability, and submission to HMRC. We also act as your agent, handle correspondence, and provide advice on allowable deductions.
You provide us with your income details and expense records. We prepare your return, ensure everything is accurate, and submit it online. We'll confirm submission and provide a copy for your records.
Typically, you'll need your P60 or P45, bank statements, records of any self-employment income and expenses, rental income details, dividend vouchers, and any other relevant financial documents.
We register with HMRC as your agent using your authorisation. This allows us to handle your tax affairs and correspondence on your behalf, making the process seamless for you.
