Frequently Asked Questions

Everything you need to know about limited company accounting.

Who needs to file a Self Assessment Tax Return in Harrow Weald?

You need to file if you are self-employed, a landlord with rental income, earn over £1,000 from a side business, have untaxed income, or receive certain benefits. Also, if your income exceeds £100,000 or you need to pay the High Income Child Benefit Charge, you must register for Self Assessment.

What is included in SATR's Self Assessment Tax Returns service?

Our service includes full preparation and submission of your SA100 tax return, calculation of your tax liability, identification of allowable expenses and reliefs, and HMRC agent registration. We also provide proactive tax planning advice and handle all correspondence with HMRC on your behalf.

How does the SA100 process work with SATR?

First, you provide us with your income and expense details. We then prepare your SA100, ensuring accuracy and compliance. We review all potential reliefs and submit the return electronically to HMRC. We also confirm your tax bill and payment deadline, keeping you informed throughout.

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

You'll need your UTR number, P60 or P45 if employed, bank statements, records of any self-employment income and expenses, rental income statements, dividend vouchers, and details of any capital gains. If you have foreign income, include relevant foreign tax documents. Our checklist makes it easy.

How does HMRC agent registration work?

When you appoint SATR, we register as your agent with HMRC. This allows us to deal with HMRC directly on your behalf, including submitting returns and responding to queries. You'll receive a copy of all correspondence, and we'll keep your details secure.

What happens if I miss the 31st January deadline?

If you miss the deadline, HMRC imposes late-filing penalties starting at £100, with additional penalties if you delay further. To avoid this, SATR proactively manages your deadlines and submits your return well in advance. If you've already missed a deadline, we can help you file as soon as possible to minimise penalties.

How does SATR's pricing work for Self Assessment Tax Returns?

We offer a transparent fixed-fee service with no hidden costs. The exact fee depends on the complexity of your tax affairs, such as the number of income sources. We provide a clear quote upfront, so you know exactly what you'll pay before we start.

Can SATR help with backdated Self Assessment Tax Returns?
