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, or a landlord with rental income. Additionally, if you have untaxed income from savings, investments, or foreign sources, or if you earn over £100,000, you may need to register for Self Assessment.

Our service includes everything needed to file your SA100 accurately and on time. This includes registering you as a client, preparing your return with all income and expenses, claiming all allowable reliefs, calculating your tax liability, and submitting your return to HMRC electronically before the deadline.

You'll provide us with your financial details, such as income statements and expense records. Our accountants will then prepare your SA100, ensuring every figure is correct and every deduction is claimed. We'll share a summary with you for approval before submitting it to HMRC.

Typically, you'll need your UTR number, P60 or P45 from employment, bank statements, records of any self-employment income and expenses, details of rental income, and any other relevant financial documents like dividend vouchers or foreign income statements.

You'll need to authorise us as your agent with HMRC, which can be done online. Once registered, we can correspond with HMRC on your behalf, view your tax records, and submit your Self Assessment Tax Returns directly.

If you miss the deadline, you'll face automatic late-filing penalties. SATR ensures you never miss the deadline by proactive monitoring and early submission. If you've already missed it, we can help you file as soon as possible to minimise any penalties.

We offer transparent fixed-fee packages with no hidden costs. The price depends on the complexity of your return, such as the number of income streams. You'll always know the cost upfront before you commit, so there are no surprises.

Absolutely. We specialise in Self Assessment Tax Returns for landlords, ensuring all rental income and allowable expenses are correctly reported. We also help with capital gains tax if you sell a property, and we ensure you claim all property-related deductions you're entitled to.
