Marbella Accountant Expands Post-Brexit Services for British Expats

British Expats on the Costa del Sol Gain Single-Firm Tax and Business Support After Brexit

Marbella, Spain – June 30, 2026 / Accountant & Tax Advisor in the Costa del Sol – MMR Consultant /

MMR Consultant, an established accountant in Marbella and Malaga, has formally broadened its dedicated service offering for British expats living and working on the Costa del Sol. The practice brings together business setup, personal and corporate tax advice, bookkeeping, and legal support under one specialist firm. The expansion responds to a sustained and documented rise in British nationals establishing or acquiring businesses in the region, following post-Brexit residency and fiscal changes that have altered how UK citizens must structure their affairs in Spain.

Specialist Support Across the Full Business Lifecycle

MMR Consultant now provides British expats with structured support at every stage of business activity in Spain – from the initial registration of a new company through to ongoing operations, and ultimately to the sale or formal closure of a business entity. This end-to-end approach addresses a gap that many British business owners encounter when navigating Spanish administrative and tax requirements without a single point of professional contact.

The practice operates across the Costa del Sol from offices in both Malaga and Marbella, giving clients access to locally based professionals who understand the specific regulatory environment in Andalusia. For British expats who have relocated or are planning to do so, the ability to receive tax advice in Marbella without engaging separate firms for accounting, legal compliance, and bookkeeping represents a practical consolidation of professional services.

Navigating Spanish Tax Obligations After Brexit

Since the United Kingdom’s departure from the European Union, British nationals in Spain are no longer treated as EU citizens for fiscal and residency purposes. This shift has introduced a range of new obligations, including changes to how worldwide income is declared, how assets are reported under the Modelo 720, and how business structures must be registered to remain compliant with Spanish law.

MMR Consultant works directly with British expats to clarify these requirements and implement compliant structures from the outset. The firm handles personal income tax filings, corporate tax obligations, quarterly VAT returns, and the bookkeeping function that underpins accurate reporting. For those operating businesses – whether a small service company, a property-related venture, or a larger commercial operation – maintaining clean and compliant accounts is a legal requirement under Spanish law, and non-compliance can result in significant financial penalties.

Business Setup and Exit Planning on the Costa del Sol

Beyond ongoing compliance, MMR Consultant provides advisory services to British nationals at the point of entering or exiting the Spanish market. Setting up a business in Spain involves selecting the correct legal structure, registering with the relevant authorities, obtaining a fiscal identification number, and understanding the social security obligations that apply to both employees and self-employed individuals. Each of these steps carries implications for both the business and the individual owner’s personal tax position.

For those looking to sell an existing business or wind down operations, the firm offers structured support through the formal closure or transfer process. This includes advising on the tax treatment of any proceeds, the cancellation of registrations, and the management of outstanding obligations to tax authorities and social security. British expats considering an exit from their Spanish business interests benefit from professional guidance that accounts for both Spanish and UK tax considerations simultaneously.
