About the service

What is the Tax Simulation in Spain?

A tax simulation in Spain is the ultimate strategic tool for financial foresight. It is a detailed forecast that calculates your potential tax liabilities before you make a critical financial move. It’s about replacing uncertainty with a clear, predictable financial map.

This service is essential for anyone on the verge of a major life or investment decision.

We create a personalized IRPF simulation (Personal Income Tax) that projects your annual tax bill. We factor in all your potential income sources: your salary, freelance earnings, rental income, and capital gains from investments.

This allows us to identify the most tax-efficient path for you. For instance, we can run a Beckham Law simulation, comparing the 24% flat rate against the standard progressive rates to show you exactly how much you could save.

Our analysis goes beyond income tax. We conduct Wealth Tax projections, which is crucial for individuals with significant worldwide assets. A simulation before you become a tax resident can save you a fortune.

Planning to buy or sell property? We provide a real estate tax simulation that calculates all the associated costs, from purchase taxes like ITP or VAT to the capital gains tax you’ll face upon selling.

For families, we simulate the impact of Inheritance and Gift Tax. Knowing the potential tax bill in advance allows you to structure your assets for a much more efficient transfer to your loved ones.

The outcome of our service is not just a number. It is a comprehensive report that explains the calculations, highlights opportunities for optimization, and provides strategic recommendations. We give you the clarity and confidence to move forward with your plans, knowing you are on the most financially sound footing possible.

 Trustindex verifies that the original source of the review is Google. I had an amazing experience working with Dario and his team throughout my visa process. They made everything completely stress-free and were incredibly helpful every step of the way. Dario speaks excellent English, which made communication easy and comfortable, and he was always responsive, patient, and clear in explaining everything. He and his colleagues handled every detail with care, efficiency, and in a very timely manner, which gave me a lot of confidence and truly made my life so much easier throughout the entire process. By far the best lawyer I’ve worked with in Barcelona. I couldn’t have asked for a better experience and would highly recommend Dario and his team to anyone needing help with visas or immigration.

 Trustindex verifies that the original source of the review is Google. A friend recommended Illay Legal  to help obtain my permanent residency in Spain. Exceptional service! Marc explained every part of the process clearly and precisely. Once I provided all the necessary details, the team did all the work: pre-completed the necessary paperwork, helped retrieve padron and digital tax certificate, secured appointments in my preferred neighbourhood and checked in with me before and after both appointments. I subsequently switched both my tax and business accountancy contracts to Marc's firm and have enjoyed the same very high level of service. Communication via email and WhatsApp, and extremely responsive to answering any small or large questions/concerns. A huge endorsement to the whole team - I would highly reccomend. Regards Ismail

 Trustindex verifies that the original source of the review is Google. Lawyers I truly trust and genuinely enjoy working with. Huge thanks to Marc and Soundous for guiding me through a very stressful documentation process over the past few years. Together we managed to resolve a complicated situation I ended up in because of a bureaucratic issue with my previous paperwork. They have well-organized processes and a lot of experience with different kinds of cases — even the tricky ones. Whenever I was stressed or freaking out, they were always there to reassure and support me. That human approach means a lot. With them, you are in very good hands 💚

FAQ

Frequently asked questions about the Tax Simulation in Spain

How is a simulation different from filing my annual tax return?

A tax return is a declaration of what happened in the past year. A tax simulation is a strategic forecast of what will happen in the future, allowing you to plan and optimize before the tax event occurs.

Can you account for the different tax rates in Madrid vs. Catalonia?

Yes, this is essential. A significant part of the IRPF, as well as Wealth and Inheritance Tax, is managed by the Autonomous Communities. Our simulations always use the specific rates and regulations of the region where you plan to reside.

How accurate is a tax simulation?

The simulation is highly accurate based on the current tax legislation and the completeness of the financial information you provide. It is a reliable tool for planning, though final figures can vary if laws change.

I want to buy a property. What taxes will you simulate?

For a purchase, we will simulate the Property Transfer Tax (ITP) if it’s a second-hand home, or VAT and Stamp Duty (AJD) if it’s a new build. We will also project your future annual property taxes (IBI).

Why is it so important to do this before moving to Spain?

Because key decisions that dramatically affect your taxes (especially Wealth Tax on your worldwide assets) can often only be structured efficiently before you become a tax resident. A pre-move simulation gives you a window of opportunity to plan.

Guiding you in every step to your bright future.
