Frequently Asked Questions
Everything you need to know about limited company accounting.
You typically need to file a Self Assessment Tax Return if you are self-employed, a sole trader, a landlord with rental income, a company director, or if you have untaxed income such as from savings, investments, or foreign sources. Even if your income is below the personal allowance, you may still need to register if you have any of these income types. Our accountants can help you determine if you need to file and ensure you meet all HMRC requirements.
Our service includes complete preparation and filing of your SA100 return, calculation of your tax liability, and identification of all allowable expenses and reliefs to reduce your tax bill. We also handle all HMRC correspondence on your behalf and provide advice on tax planning. We ensure your return is submitted accurately and on time, giving you peace of mind throughout the process.
Once you engage our services, we will send you a secure online questionnaire to gather your income and expense details. You can also upload documents directly to our portal. Our accountants will then prepare your return, review it with you for accuracy, and once you approve, we submit it to HMRC digitally. You will receive a copy of your submitted return and a breakdown of your tax liability, if any.
Typically, you will need to provide your P60 or P45 for employment income, bank statements showing interest, dividend vouchers, records of any rental income and expenses, business income and expense records, and details of any capital gains or foreign income. Our team will guide you on exactly what is needed for your specific circumstances to ensure nothing is missed.
When you appoint SATR as your agent, we will register with HMRC on your behalf. This involves linking your UTR (Unique Taxpayer Reference) to our agent account, which allows us to submit your return and receive correspondence from HMRC. This process ensures we can manage your tax affairs seamlessly and keep you informed of any updates.
If you miss the deadline, HMRC will issue automatic penalties, starting with an initial fine and then additional daily penalties if the return remains outstanding. Our service proactively reminds you of upcoming deadlines and ensures your return is filed well in advance, so you never have to worry about late-filing penalties. We also handle any penalty appeals on your behalf if you have a reasonable excuse.
We offer transparent, fixed-fee pricing with no hidden costs, so you know exactly what you will pay upfront. The fee depends on the complexity of your tax affairs, such as the number of income sources and the level of detail involved. We will provide a clear quote before you commit, ensuring there are no surprises.
Absolutely. Our accountants are experienced in handling foreign income for Self Assessment Tax Returns in South Wales. We ensure you correctly report overseas earnings, investments, or rental income, and claim any applicable foreign tax credit relief. We also help you understand your UK tax obligations, including any need to declare worldwide income.
