Self Assessment Tax Returns in Isleworth

You typically need to file if you are self-employed, a sole trader, a landlord with rental income, or have other untaxed income such as dividends or foreign income. If you earn over £1,000 from self-employment or rental income, or if you need to pay the High Income Child Benefit Charge, you must register. SATR can help you determine your filing requirement.

Our service includes complete preparation and filing of your SA100 return, calculation of your tax liability, and identification of all allowable expenses and reliefs. We also handle HMRC correspondence on your behalf and provide year-round tax planning advice. We ensure your return is accurate and submitted before the deadline.

First, you provide us with your income and expense details, which you can do via a simple online form or by uploading documents. Our accountants then prepare your SA100, ensuring all figures are correct and all reliefs are claimed. We submit the return digitally to HMRC and send you a confirmation once filed.

You'll need to provide documents showing your income, such as P60s, P45s, bank statements, dividend vouchers, rental income records, and receipts for allowable expenses. If you're self-employed, a summary of your business income and expenses is essential. Our team will guide you on exactly what we need.

Once you authorise SATR as your agent, we register with HMRC using your Unique Taxpayer Reference (UTR). This allows us to file your return on your behalf and correspond with HMRC directly. We handle the entire registration process, so you don't have to worry about the paperwork.

If you miss the deadline, HMRC will issue an automatic £100 penalty, with further penalties if you delay longer. SATR monitors all deadlines and ensures your return is filed well before the due date. If you've already missed a deadline, we can still help you file as soon as possible to minimise penalties.

We offer transparent fixed-fee packages with no hidden costs. The exact price depends on the complexity of your return, but we always provide a clear quote upfront. This means you know exactly what you'll pay before we start, with no surprises.

Yes, we specialise in helping individuals with foreign income, including foreign rental income, dividends, and capital gains. Our accountants are experienced in reporting foreign income correctly and claiming any applicable foreign tax credit relief, ensuring you remain compliant with HMRC.
