UK CIS and Self Assessment Tax Returns

Support for construction subcontractors and the self-employed. Speak directly with Ernestas in English or Lithuanian. Over 20 years of experience in managing UK accounting and taxation matters.

Who is this service for?

For those working under CIS, sole traders, or individuals with both PAYE and self-employed income. We assist with UK tax matters even if you are currently living in Lithuania or working abroad.

What we provide

We will review your income, CIS tax deductions, and business expenses. We prepare your accounts and annual Self Assessment return, calculate any tax owed or refund due, and explain the figures. We submit the return once you approve the data and HMRC agent authorisation is set up. If required, we can also assist you with the initial tax registration.

What documents are needed?

• CIS payment and deduction statements.
• Business income invoices and bank statements.
• Receipts and invoices for expenses, including travel records if applicable.
• P60 or P45 forms if you were also employed.
• Information regarding other income sources and any relevant letters received from HMRC.

We will confirm the final list based on your specific case. If you lack CIS statements, please contact your contractor.

How the process works

1. We discuss your situation and agree on the fee.
2. You provide the documents, which we review to identify any missing details.
3. We prepare the return, explain the calculations, and get your approval.
4. We submit the return to HMRC and notify you once it is filed.

What are the fees?

Usually £198 including VAT or 12% of the tax refund (whichever is higher). This equates to £165 + VAT or 10% + VAT. For very simple cases, a lower fee may be agreed upon. We confirm the final price before starting work. Ongoing bookkeeping and MTD services are quoted separately based on your needs.

Is a tax refund always guaranteed?

No. The result depends on your total annual income, allowable expenses, tax already deducted, and other factors. You may receive a refund or have a tax liability to pay. We cannot guarantee the refund amount or HMRC processing times in advance.
