Frequently Asked Questions

Everything you need to know about limited company accounting.

You 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 you have untaxed income from savings, investments, or foreign sources. If your income exceeds £1,000 from self-employment or you earn over £100,000, you must also file. SATR can help you determine if you need to file and handle the entire process.

Our service includes full preparation and filing of your SA100 return, including all supplementary pages for income from employment, self-employment, property, dividends, and capital gains. We also calculate your tax liability, identify allowable expenses and reliefs, and submit your return to HMRC digitally. We register as your agent and handle all correspondence with HMRC on your behalf.

First, you provide us with your income and expense details, and we'll handle the rest. Our accountants review your information, ensure everything is accurate, and complete the SA100 form. We then submit it electronically to HMRC before the deadline. You'll receive a copy of your return and a breakdown of your tax liability, so you know exactly where you stand.

You'll need to provide your National Insurance number, UTR number (if you have one), P60 or P45 from your employer, bank statements, records of any self-employment income and expenses, rental income details, dividend vouchers, and any other relevant financial documents. We'll guide you on exactly what's needed, so you don't have to worry about missing anything.

Once you instruct us, we'll register as your agent with HMRC. This allows us to deal with HMRC on your behalf, including submitting your return and responding to any queries. We'll handle the registration process seamlessly, and you'll receive confirmation from HMRC that we're authorised to act for you.

If you miss the deadline, HMRC will issue a late-filing penalty, which increases the longer you delay. However, with SATR, we ensure your return is submitted well before the deadline, so you never have to worry about penalties. If you've already missed a deadline, we can still help you file quickly and minimise any potential fines.

We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on your individual circumstances, such as the complexity of your income sources, but we'll always provide a clear quote upfront. You'll know exactly what you're paying before we start, so there are no surprises.
