I am a certified UK tax and accounting professional who works daily with clients across various industries — small businesses, international entrepreneurs, and non-residents entering the UK market. My role is to help them navigate HMRC requirements, build effective tax strategies, and keep their businesses compliant, stable, and financially protected. My approach combines strong academic training, international experience, and a practical understanding of how UK taxation works in real business environments. Clients rely on me for Self Assessment, CT600, VAT, CIS, company formation, and long-term tax advisory. I focus on accuracy, transparency, and tailored solutions, because every business has its own structure, risks, and goals. I work with both UK-based clients and those operating internationally, providing the support they need to manage their obligations confidently within the UK tax system.
In 2026, a UK-based service company approached me, accountant and VAT advisor Iryna Shmulenko, after exceeding the VAT registration threshold but failing to register on time. The business had experienced rapid growth in sales across the UK and Europe, yet the directors were unfamiliar with VAT obligations and Making Tax Digital (MTD) requirements. Without urgent professional support, the company faced significant risks of HMRC penalties, backdated VAT liabilities, and compliance disruptions affecting cash flow and operations.
Client's core challenges:
— Late VAT threshold breach without timely registration;
— Risk of HMRC penalties and backdated VAT assessments;
— Lack of understanding of Making Tax Digital (MTD) compliance requirements;
— Need for urgent VAT number issuance and HMRC communication;
— Incorrect VAT treatment of sales and expenses affecting cash flow;
— Requirement for ongoing quarterly VAT Returns submission support.
Strategic Approach to VAT Registration and MTD-Compliant Reporting
My initial step was to conduct a full review of the client’s turnover history, sales structure, and invoicing practices. This audit confirmed that the business had exceeded the VAT threshold earlier than expected, requiring immediate registration and corrective action to minimize penalties and ensure full compliance with HMRC regulations.
I developed a tailored VAT compliance strategy focusing on the following pillars:
- Completing urgent VAT registration and managing HMRC correspondence.
- Reviewing historical transactions to determine correct VAT liability and effective registration date.
- Implementing an MTD-compliant VAT reporting system using approved accounting software.
- Preparing accurate quarterly VAT Returns with proper input and output VAT calculations.
- Advising on VAT planning to improve cash flow and prevent future compliance risks.

The implementation phase involved full VAT registration support, corrective compliance measures, and ongoing reporting setup. I provided comprehensive assistance for:
