Tax · accounting · employment · corporate · legal advice
Professional support for individuals and small and medium-sized businesses. We handle communication with the Tax Agency, the Social Security authorities and other public administrations.
Personalised advice, efficient management and legal certainty.
Services
We work for a fixed monthly fee or on a one-off basis. We tell you the price before we start.
We prepare and file all your quarterly and annual returns with the Spanish Tax Agency, and look for ways to pay only what is due within the law.
We keep your books up to date and meet every legal requirement for records and accounts, so you always know how your business is doing.
We look after your staff from start to finish: contracts, payroll, social security contributions and any issue with Social Security. We have our own HR team.
We set up your company from start to finish and support you through every later change: articles of association, shareholders, capital and management.
As a firm led by a practising lawyer, we advise and represent you before the authorities and the courts. We monitor your electronic mailbox and respond to every official notice on your behalf.
We advise you before you start and draw up your business plan. Once the company is up and running, we help you consolidate it and grow on realistic figures.
Tax calendar
The main Spanish Tax Agency deadlines for self-employed professionals and companies.
If the last day falls on a Saturday, Sunday or public holiday, the deadline moves to the next working day.
If you are a client, we take care of all of them.
Achievements
We support companies and entrepreneurs from the birth of their idea to the consolidation of their business, providing advice and legal backing at every stage. And when the authorities make mistakes, we defend their rights and interests firmly and professionally.
Claims against the Tax Agency and Social Security
We defend directors, shareholders and companies against secondary liability claims and penalties from the Spanish Tax Agency and Social Security, from the first submissions through to the courts.
We handled the whole process: company name, articles of association, notary, registration and tax registration.
We advise entrepreneurs and draw up solid business plans before they take the leap.
We help established businesses consolidate: we put their accounts, taxes and staffing in order so they can grow with confidence.
We represent clients from all over Europe who have business or interests in Spain.
