Accountants in Spain: Tax Law and Accounting Services

Solicitors and gestors specialising in tax law and accounting in Valencia

Finding qualified accountants in Spain who understand both Spanish fiscal law and the realities of international clients is harder than it should be.

Most domestic firms work fluently in Spanish only and treat non-resident or expat cases as exceptions rather than core practice.

At Delaguía y Luzón, our accountants in Spain have advised international clients for more than 65 years from our Valencia office, working in English, French, Spanish and Russian.

We act for UK nationals, EU citizens, businesses with cross-border operations, self-employed professionals (autónomos), and high-net-worth individuals with assets in multiple jurisdictions.

This page sets out what our tax law and accounting team does, the Spanish tax framework you need to understand, and how the Valencian Community compares to other regions on personal and corporate tax.

According to AEAT data, more than 5.8 million non-resident tax filings (Modelo 210) were processed in Spain in 2024, reflecting the scale of the international client base requiring specialised accountants and tax advisers.

Solicitors, gestors and accountants in Spain working under one roof

Spain’s professional landscape splits tax and accounting work across three distinct figures: the abogado fiscalista (tax lawyer), the gestor (administrative tax practitioner), and the asesor fiscal or accountant.

Many international clients arrive expecting a single point of contact and instead find themselves coordinating between two or three providers.

Our Valencia firm consolidates these roles.

The same team that drafts your corporate structure files your Modelo 200, advises on Beckham Law eligibility, and handles AEAT correspondence if a tax inspection arises.

The Spanish tax framework that our accountants navigate daily

Spanish fiscal law is administered by the Agencia Estatal de Administración Tributaria (AEAT), with regional adjustments handled by each Comunidad Autónoma.

The Valencian Community has its own Conselleria d’Hisenda applying delegated tax powers on inheritance, gifts, and certain personal income tax brackets.

Below are the core taxes our accountants in Spain handle for international clients.


Resident individuals are taxed on worldwide income on a progressive scale combining state and regional brackets.

In the Valencian Community for 2026, the combined marginal rate reaches 54% on income above €300,000, while the lowest bracket starts at 19%.

Non-residents file Modelo 210 at a flat 19% (EU/EEA residents) or 24% (non-EU residents) on Spanish-source income.

The general rate is 25%.

Newly incorporated companies pay 15% in the first profitable year and the following one.

Under Startup Law 28/2022, qualifying startups apply 15% for the first profitable year and the four following years, subject to ENISA certification.

Our team has covered the Spanish corporate tax framework in depth in a separate guide.

Spanish residents holding assets abroad worth more than €50,000 in bank accounts, securities, or real estate must file Modelo 720 annually before 31 March.

The European Court of Justice ruling of 27 January 2022 (Case C-788/19) struck down the disproportionate sanctions regime, but the filing obligation remains.

Our accountants in Spain prepare Modelo 720 for clients with UK pensions, US brokerage accounts, French rental properties, and similar foreign holdings.

The IRPF return (Modelo 100) is filed between April and June.

The corporate return (Modelo 200) is due within 25 calendar days following the six months after the fiscal year-end, typically July for calendar-year companies.

Standard IVA is 21%, with reduced rates of 10% and 4% for specific goods and services.

Inheritance and Gift Tax (ISD) is regionally administered, with the Valencian Community offering a 50% quota reduction and a €100,000 individual allowance for Group I and II heirs.

Local property taxes (IBI, Plusvalía Municipal) vary by municipality and are coordinated with each town hall.

Comparing accountants in Spain by region: where Valencia stands

The choice of region is not cosmetic.

It directly affects your IRPF marginal rate, ISD allowances, and wealth tax liability.

RegionTop IRPF Marginal Rate (2026)Wealth TaxISD Direct Family (Group II)
Valencian Community54%Applies above €500,00050% quota reduction + €100,000 allowance

Catalonia50%Applies from €500,000Up to 99% reduction depending on amount
Andalusia47%100% bonification99% bonification for direct family

Madrid and Andalusia look more competitive on headline rates.

The trade-off is property cost, urban density, and access to a Mediterranean lifestyle.

For most of our UK and northern European clients, Valencia’s combination of moderate tax burden, cost of living, and quality of life remains commercially rational.

 

What our accountants in Spain do for international clients

Our scope covers the full lifecycle from arrival to exit.

We assess where you are tax-resident under Spanish criteria (Article 9 LIRPF) and the Spain-UK Double Tax Treaty, advising on tie-breaker rules where dual residency arises.

This determination drives every subsequent decision.

Article 93 LIRPF allows qualifying inbound workers to be taxed as non-residents for up to six tax years, paying a flat 24% on Spanish employment income up to €600,000. We assess eligibility, file the Modelo 149 application within the six-month window, and manage annual Modelo 151 filings.
We register clients with AEAT and the Tesorería General de la Seguridad Social, set up the correct economic activity codes (IAE), and manage quarterly IVA and IRPF filings (Modelo 303, Modelo 130). Our self-employed Spain tax reduction guide covers the deduction strategies in detail.

We incorporate Spanish entities (Sociedad Limitada with €1 minimum capital under Startup Law 28/2022, Sociedad Anónima, branch registrations) and file the annual accounts package: Modelo 200, Modelo 202 (instalments), Cuentas Anuales at the Mercantile Registry, and Modelo 232 for related-party transactions.

We coordinate cross-border wills under EU Regulation 650/2012 (Brussels IV), draft Spanish testamentos abiertos and structure lifetime gifts to optimise ISD exposure. For UK clients with assets in both jurisdictions, we work alongside UK-side advisers to align estate plans.
