Frequently Asked Questions

Everything you need to know about limited company accounting.

Who needs to file a Self Assessment Tax Return in Derry?

You need to file if you are self-employed, a landlord, a company director, or have untaxed income such as from investments or foreign earnings. If your income exceeds £1,000 from self-employment, you must register for Self Assessment. Our team can help you determine your obligations.

What is included in your Self Assessment Tax Return service?

Our service includes full preparation and submission of your SA100 tax return, calculation of your tax liability, and advice on allowable expenses and reliefs. We also handle HMRC correspondence and ensure your return is filed correctly and on time.

How does the SA100 filing process work with SATR?

First, you provide us with your income and expense details. We then prepare your SA100, ensuring every figure is accurate. After you review and approve, we submit it electronically to HMRC. We keep you informed throughout the process.

What documents do I need to provide for my Self Assessment Tax Return?

You'll need your P60 or P45 if employed, records of any self-employment income and expenses, bank interest statements, dividend vouchers, and details of any rental income or capital gains. We'll guide you on exactly what's required.

How does HMRC agent registration work?

Once you authorise us as your agent, we can deal with HMRC on your behalf. We handle the registration process, which involves linking your UTR number to our practice. This allows us to file your return and correspond with HMRC directly.

What happens if I miss the 31st January deadline?

If you miss the deadline, you may incur late-filing penalties, which increase over time. To avoid this, we ensure your return is submitted well before the deadline. If you've already missed it, we can help you file as soon as possible to minimise penalties.
