Tax advisory and legal services
Two areas of work in the same firm: tax (personal, self-employed and company taxes, and defence before the tax office) and legal and estate work (inheritances and property purchases and sales). Our office is in La Línea de la Concepción, and we also work online with clients across Spain and abroad.
Tax advisory
For individuals, self-employed people and companies. If you work in Gibraltar and live in Spain, see our tax advice for Gibraltar workers; for the deadlines of each form, see the 2026 tax calendar.
Spanish income tax return (declaración de la Renta)
Preparation and filing, deductions, previous years, supplementary returns and corrections. Also remotely.
Self-employed
Registration with the tax office, quarterly VAT and personal income tax (IRPF), withholdings, and the choice between working as self-employed or through a company. We do not run payroll or monthly bookkeeping.
Setting up a company
Setting up a limited company (S.L.), registration with the tax office and corporate income tax (Impuesto sobre Sociedades).
Tax planning and wealth
Wealth tax (Impuesto sobre el Patrimonio), Form 720 (modelo 720) and decisions with tax effects, reviewed before you take them.
Non-residents and Gibraltar
Form 210 (modelo 210), NIE and tax representative, tax residence, cross-border workers and double taxation.
International moves and the Beckham Law
Change of tax residence, the special regime for people moving to Spain (Beckham Law), double taxation and assets abroad.
Tax notices, audits and penalties
Replying to tax notices (requerimientos), limited tax reviews, tax audits, allegations, appeals and claims before the regional economic-administrative tribunal (TEAR).
Filings with the Andalusian regional government
As registered social collaborators (colaboradores sociales), we file inheritance tax, gift tax and property transfer tax (Forms 600, 650 and 660) across Andalusia.
We handle the whole inheritance: will or declaration of heirs, inventory, acceptance, division of the estate, inheritance tax, municipal capital gains tax (plusvalía municipal) and registration at the Land Registry. The same team looks after the legal and the tax side, so every heir knows from the start what they will have to pay.
Not sure which service your case needs?
Tell us about it in two lines on WhatsApp and we will tell you who in the firm will handle it and what the next step is.
We review the transaction before you hand over any money: ownership, charges on the property, deposit contract (contrato de arras) and sale contract, taxes on the purchase or the sale, the 3% withholding if a non-resident sells, signing and registration. For residents and foreign owners buying or selling in La Línea, Sotogrande, San Roque and the rest of the Campo de Gibraltar (the area around Gibraltar).
Online consultation with an adviser
If you live far away or prefer not to travel, we see you by video call: one hour with one of our tax advisers or lawyers, at a fixed price you know when you book.
