If you own a property in Spain but live abroad, you will normally have Spanish tax obligations even if you never rent out your property.

For most non-resident property owners, this means filing Modelo 210, the Spanish Non-Resident Income Tax return.

Traditionally, foreign property owners have relied on an accountant, gestor or tax adviser in Spain to prepare their annual declaration. Today, however, online tax services make it possible to handle a straightforward Spanish property tax return yourself.

So which option is better?

In this guide, we compare DIY Modelo 210 filing vs using an accountant, looking at cost, convenience, complexity and when professional tax advice may still be the better choice.

What Is Modelo 210?

Modelo 210 is the tax form used by the Spanish Tax Agency, Agencia Tributaria (AEAT), to declare certain Spanish-source income received by non-residents.

For property owners, it commonly applies in three situations:

Non-rented property

If you own a holiday home or second property in Spain that is available for your own use, you may still have to pay tax based on an imputed or theoretical income from the property.

This is commonly known as imputed income tax or renta imputada.

Rental property

If you rent your Spanish property, the rental income must generally be declared through Modelo 210 under the rules applicable to non-residents.

Selling a Spanish property

Modelo 210 can also be relevant when a non-resident sells property in Spain, particularly in connection with capital gains taxation.

For this article, however, we are mainly comparing the options available to ordinary non-resident homeowners filing their recurring Spanish property tax.

Option 1: Filing Spanish Property Tax Yourself

The first option is DIY filing.

In theory, you can deal directly with the Spanish tax system yourself. But for foreign owners, the challenge is often not the tax itself. It is understanding the terminology, calculations and filing procedures.

You may need information including:

• Your NIE number

• Property address

• Cadastral reference

• Cadastral value

• Ownership percentage

• Country of tax residence

• Date of acquisition

• Applicable tax year

• Details of rental income where relevant

For a non-rented property, you must also establish which percentage should be applied to the cadastral value when calculating the imputed income.

Once the correct taxable base has been established, the applicable non-resident tax rate must be applied.

A relatively simple tax can therefore become confusing if you are unfamiliar with Spanish tax terminology.

Advantages of DIY Filing

The biggest advantage is normally cost.

You avoid paying the annual fee charged by a traditional accountant or gestor.

DIY filing also gives you greater control. You can prepare the declaration when convenient rather than sending documents back and forth and waiting for someone else to process them.

For someone with a straightforward situation who understands Modelo 210, doing it yourself can therefore make perfect sense.

Disadvantages of Filing Completely on Your Own

The main disadvantage is that you are responsible for getting everything right.

Common questions include:

Is this the correct cadastral value?

Should I use the 1.1% or 2% calculation?

Which tax rate applies to me?

Which tax year should I declare?

How do I deal with joint ownership?

How do I pay from abroad?

What happens if I owned the property for only part of the year?

A mistake involving one of these details can result in an incorrect declaration.

This is why many foreign property owners who would otherwise be comfortable filing themselves still prefer some form of guided system.

Option 2: Using an Accountant or Gestor

The traditional alternative is to appoint an accountant, gestor or tax adviser in Spain.

You provide your documents and property information, and the professional prepares the declaration for you.

Advantages of Using an Accountant

The most important advantage is professional assistance.

This can be particularly valuable when your tax situation is complicated.

For example, professional advice may be worthwhile if you:

• Have several properties in Spain

• Have complicated rental income

• Have missed previous tax declarations

• Have received a notification from the Spanish Tax Agency

• Are unsure about your tax residency

• Have complicated deductions or expenses

• Have inherited or recently sold property

• Need wider Spanish or international tax advice

An accountant can also advise you about issues beyond Modelo 210.

That can be important because an online property tax filing service and a tax adviser are not necessarily providing the same service.

Disadvantages of Using an Accountant

For a straightforward annual Modelo 210 declaration, the main disadvantage is often cost.

You may also need to send the same information to your accountant each year, wait for the declaration to be prepared and communicate about documents or payment.

For complicated tax affairs, this may be worthwhile.

But a non-resident who simply owns one holiday apartment in Spain may wonder whether a traditional accounting service is necessary for the same recurring declaration every year.

DIY vs Accountant: Which Is Cheaper?

This is where online tax filing has significantly changed the market.

There are effectively now three choices rather than two:

1. Completely DIY

Prepare and submit the Modelo 210 yourself using the Spanish tax system.

2. Guided online filing

Use a specialised online service that guides you through the information required and handles the declaration process.

3. Traditional accountant or tax adviser

Provide your information to a professional who prepares the declaration and can provide broader individual tax advice.

For many straightforward non-resident property owners, the middle option offers an attractive balance between price and convenience.

A Third Option: Guided DIY Modelo 210 Filing

EasySpanishTax was created specifically for non-resident property owners who want a simpler alternative to dealing with Spanish property tax paperwork themselves or paying for a traditional accountant for a straightforward declaration.

Instead of navigating complicated tax terminology, you complete a guided online form with information about yourself and your Spanish property.

The process is designed specifically around Modelo 210 for non-resident property owners in Spain.

Your declaration is then prepared and submitted, and you receive confirmation.

This provides much of the convenience people traditionally look for from an accountant while keeping the process online and focused on the specific tax declaration you actually need.

How Long Does Online Modelo 210 Filing Take?

For a straightforward property declaration, completing the EasySpanishTax online process can take only a few minutes if you have the necessary information available.

You enter your personal and property details, review the information and complete the process online.

Your declaration is also saved, making the following year's filing easier because you do not have to start again from scratch.

This can be particularly useful for foreign homeowners who expect to file Modelo 210 every year.

What Documents and Information Should You Have Ready?

Before starting your Spanish non-resident property tax declaration, it is useful to have the following available:

• NIE number

• Passport or identification details

• Spanish property address

• Cadastral reference

• Cadastral value

• Latest IBI receipt

• Ownership percentage

• Purchase or acquisition date

• Country of tax residence

• Rental information if the property has been rented

If two or more people own the property, remember that each owner generally has their own tax obligation according to their ownership share.

DIY vs Accountant: Quick Comparison

There is therefore no single option that is right for every property owner.

The best solution depends on the complexity of your circumstances.

When Does DIY Spanish Property Tax Make Sense?

A DIY or guided online approach can be particularly suitable when:

You are a non-resident in Spain.

You own a straightforward holiday home, apartment or villa.

Your ownership structure is simple.

You understand what needs to be declared or are using a system that guides you through the process.

You mainly need to complete your annual Modelo 210 rather than receive wider tax planning advice.

For these owners, paying for full accounting services every year may be unnecessary.

When Should You Consider an Accountant?

There are situations where saving money should not be the main consideration.

Consider obtaining professional tax advice if your circumstances involve complex tax residency questions, substantial rental activity, several sources of Spanish income, inheritance, previous undeclared years, tax inspections or correspondence from AEAT.

The same applies if you simply do not understand your tax position.

An online filing platform is designed to make a specific declaration easier. It should not replace personalised professional advice where that advice is genuinely required.

Can I File Modelo 210 From Abroad?

Yes.

Non-resident property owners do not normally need to travel to Spain simply to deal with their annual Modelo 210.

The process can be handled online from countries such as the UK, Ireland, Sweden, Norway, Denmark, Germany, the Netherlands, Belgium, France and many other countries.

This is particularly useful for people who use their Spanish property only for holidays or during part of the year.

Is an Accountant Necessary for Modelo 210?

Not necessarily.

There is no general requirement that an accountant must prepare a straightforward Modelo 210 simply because you are a foreign property owner.

The important thing is that the declaration is prepared correctly and submitted within the applicable deadline.

If your circumstances are straightforward, you can potentially handle the process yourself or use a specialised online filing service.

If your circumstances are complicated, professional advice may be worth the additional cost.

Why More Non-Residents Are Filing Spanish Property Tax Online

Spanish property ownership has become increasingly international.

Owners may live thousands of kilometres away from their holiday home and manage their banking, insurance, utilities and property administration online.

Tax filing is increasingly becoming part of that same digital approach.

Instead of arranging meetings or repeatedly emailing the same property documents, owners can provide the required information online and keep records available for future declarations.

For a recurring obligation such as Modelo 210, this can make annual compliance considerably easier.

The Bottom Line: DIY or Accountant?

If you have complicated Spanish tax affairs, an experienced accountant or tax adviser can be money well spent.

But if you simply own a holiday home or other straightforward property in Spain as a non-resident, you may not need traditional accounting services just to complete your annual property tax declaration.

The key is finding the right level of assistance.

Completely DIY filing offers the lowest possible cost but requires more knowledge and responsibility.

An accountant provides individual professional assistance but usually at a higher cost.

A guided online Modelo 210 service sits between the two, combining a straightforward digital process with professional submission of the declaration.
