Frequently Asked Questions

Everything you need to know about limited company accounting.

You need to file if you're self-employed, a landlord, a company director, or have untaxed income such as from savings, investments, or foreign income. If you earned over £1,000 from self-employment or renting out property, you must register for Self Assessment. Our accountants can help you determine if you need to file.

Our service includes preparation and submission of your SA100, calculation of your tax liability, and identification of allowable expenses and reliefs. We handle all correspondence with HMRC on your behalf, acting as your agent. We also provide year-round support to ensure you're fully compliant.

First, you provide us with your income details and expenses, either through our secure online portal or by post. We then prepare your SA100, ensuring accuracy and completeness. After your approval, we submit it to HMRC electronically, well before the deadline. We'll keep you informed throughout the process.

You'll need your UTR number, P60 or P45 from employment, details of any self-employment income and expenses, rental income statements, dividend and interest statements, and any records of foreign income. If you're unsure, we can send you a comprehensive checklist. Our team will review everything to ensure nothing is missed.

To act as your agent, we need your authorisation. This involves linking your UTR to our agent account via HMRC's online service. Once linked, we can file your return and manage your tax affairs on your behalf. We handle the entire process, making it seamless for you.

If you miss the deadline, you'll face an automatic £100 penalty, and further penalties accrue if payment is late. However, with SATR, we monitor deadlines and submit your return well in advance, eliminating the risk. If you've already missed a deadline, we can still help you file and minimise any penalties.

We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your return, but you'll always know the price upfront before we start. We'll provide a clear quote tailored to your situation, ensuring you get value for money.
