In this guí we explain which documents you need to do the declaración of the rent in Mallorca, which are the most common, which you must review according to your situación and why having professional help can avoid more than one problem.

Why it is important to properly gather the documents before filing the tax return

Before filing the IRPF, it is not enough to enter the draft and confirm the data without further action. Although the Tax Agency already incorporates part of the fiscal information, it does not always appear correctly, nor is everything that affects you automatically reviewed.

Properly preparing the documentation is important because it helps you to:

• check that the tax data is correct;
• detect errors or incomplete data;
• include deductions or personal circumstances that may benefit you;
• avoid later requirements or corrections;
• file the income with greater certainty.

Many people believe that, if the Tax Agency already has the information, there is no need to review anything. But the reality is that a poorly reviewed declaration can become costly.

What documents do you need to file the tax return in Mallorca if you are an employee

If you work as an employee, there is a series of basic documents that it is advisable to have on hand before filing the tax return.

Certificate of income and withholdings

It is one of the most important documents. The company usually provides a certificate where the earnings from work and the withholdings made during the fiscal year appear.

Although in many cases this data already appears reflected in the draft, it is advisable to review and compare them.

DNI or NIE of the taxpayer and of the family unit

You will need to correctly identify all persons included in the declaration. If you file a joint declaration, you must also have the spouse's documentation. If there are children, it is advisable to also review their personal and tax data.

Updated bank details

The account number is important whether the result is a refund or a payment. An error here can cause unnecessary issues.

Cadastral references of properties

If you own a home, a second residence or any other property, it is advisable to review the cadastral data correctly. This information influences various sections of the tax return.

What documents you need to file the tax return in Mallorca if you are self‑employed

If you are self‑employed, the required documentation is usually broader. In these cases, filing the tax return without control can cause significant errors.

Income and expense books

It is essential to have the obtained income and deductible expenses of the fiscal year well organized. A general estimate is not enough: everything must be supported and properly classified.

Issued and received invoices

Invoices are essential to justify both income and expenses. They must be organized and correspond to real transactions linked to the economic activity.

Quarterly forms and annual summary

It is important to have on hand the forms presented during the year, especially those related to VAT, installment payments and advance payments, so that everything lines up correctly in the final declaration.

Proofs of fees, supplies and other deductible expenses

According to the type of activity, there may be deductible expenses related to freelancers, fees, material, supplies, travel or housing that affects the activity. Each case should be reviewed with discretion.

What documents you need to file the income tax return in Mallorca if you have a home or properties

In Mallorca many tax returns include primary residences, second homes, rentals or shared properties. Therefore this section is especially relevant.

Deed or acquisition data of the property

It is advisable to have on hand the purchase date, acquisition value and other data related to the property, especially if there has been a sale, inheritance or changes of ownership.

IBI receipts and cadastral reference

These documents help correctly verify the property data in the tax return.

Rental contract if you have a leased dwelling

If you have earned rental income, you need to have the contracts located and the amounts received during the fiscal year.

Proofs of expenses related to the property

In some cases, certain expenses associated with the rental or maintenance of the property may have tax relevance. Therefore it is important to keep the supporting documentation.

What documents you need to make the income tax declaration in Mallorca if you are a foreigner or not a fiscal resident in Spain

Mallorca has a significant volume of international residents, foreign owners and people with mixed tax situations. In these cases, the documentation must be reviewed with even more care.

NIE, passport and tax residence data

It is essential to correctly verify identity and tax residence status, as this determines how taxation should be treated.

Certificates of income obtained inside and outside Spain

Depending on the case, it may be necessary to review income from other countries, employment income, dividends, rentals or other sources.

Documentation on accounts, assets or investments abroad

In certain situations, having assets or income outside of Spain can affect the tax return and must be reviewed on an individual basis.

Professional case review

When there is a tax connection with more than one country, prudence is key. In these profiles it is not advisable to improvise or confirm drafts without prior analysis.

Other important documents to file the tax return in Mallorca

In addition to the basic documentation, there are other papers that can be very important depending on your personal or family situation.

Bank certificates

Interest, accounts, deposits or financial products can influence the return. It is advisable to have the certificates issued by the banks at hand.

Information about loans or mortgages

In some cases, especially if there are specific circumstances related to housing, it is advisable to review this documentation.

Proofs of insurance, donations or contributions

Certain contributions, donations or specific situations can have tax effect. Without proper documentation, they cannot be properly assessed.

Updated family data

Marriage, separation, birth of children, disability, changes of residence or dependency situations can affect the tax return. All that information must be up to date.

Common mistakes when gathering documents for the tax return

Knowing which documents you need to do the declaración of the rent in Mallorca also implies knowing which errors should be avoided.

Thinking that the draft is always complete

One of the most common mistakes is confirming the draft without reviewing it thoroughly. Not everything always appears properly incorporated.

Do not review property data

Properties often generate many errors: incorrect cadastral references, ownership percentages poorly reflected, or incomes not correctly allocated.

Forgetting relevant income or expenses

This happens often with freelancers, rentals or taxpayers with multiple sources of income.

Do not keep receipts

Although it is not always necessary to attach them when filing the tax return, it is important to keep the documentation in case it is needed to justify any data later.

When it is advisable to go to an accounting firm to file the income tax return in Mallorca

There are simple cases, but also many situations where having professional support makes a difference.

If you are self-employed

The self-employed's tax return usually requires more review, more documentation, and more technical judgment.

If you have rentals or multiple properties

The more assets are involved, the easier it is to make mistakes.

If you are a foreigner or have income outside Spain

Here the review must be even more careful.

If you want to avoid mistakes and save time

Many people do not only aim to file the tax return, but to file it correctly, safely, and without spending hours trying to interpret every detail.
