Take the stress out of tax season. Whether you are a sole trader, a landlord, or a high-earning director, our Shiney Row team provides accurate, timely, and jargon-free tax support for clients in Sunderland, Durham, and across Tyne and Wear.






Self Assessment is how HMRC collects Income Tax from people who need to report income that is not fully taxed at source. This can include sole traders, landlords, company directors, investors and people with additional income. HMRC says people and businesses with other income may need to report it through a Self Assessment tax return.
At LSC Accounting, we make the process clear from start to finish. We review your income, expenses and allowances, prepare your return and explain what needs to be paid, when it is due and what happens next.
We accurately calculate your tax liability and prepare your full Self Assessment return, ensuring all income sources and eligible expenses are correctly captured.
Our team reviews your records to identify all legitimate tax-deductible expenses, helping you reduce your tax bill and keep more of what you earn.
We handle the full digital submission of your return to HMRC well before the January 31st deadline, ensuring you avoid costly late-filing penalties.
Beyond just filing, we provide year-round guidance on tax planning and "Payments on Account," helping you manage your cash flow effectively.
Our Self Assessment service is designed to remove the pressure from tax return season. We keep the process organised, explain what information is needed and make sure your return is prepared accurately and submitted on time.
