1. Everything you need to know about the VAT declaration model in Spain (model 303)


Model 303 is a tax form used to declare Value Added Tax (VAT).

It is presented quarterly and is mandatory for all companies and self-employed persons that carry out operations subject to VAT in Spain.

VAT is an indirect tax that is applied to commercial transactions in most countries of the world.

In Spain, the general VAT rate is 21%, although there are reduced rates of 10% and 4% for certain goods and services. Companies and self-employed persons that carry out operations subject to VAT must collect the corresponding tax and then declare and pay it through this model.

This model includes the income and expenses corresponding to the quarter, as well as the VAT collected (tax that has been charged to customers) and the VAT borne (tax that has been paid to suppliers).

If the input VAT is greater than the VAT collected, a refund of the excess can be requested.

2. When should form 303 be filed?


The filing dates of model 303 are as follows:

– First trimester: from April 1 to 20.

– Second trimester: from July 1 to 20.

– Third trimester: from October 1 to 20.

– Fourth quarter: from January 1 to 30 of the following year.

It is important to take into account that, if you opt for the presentation and payment through direct debit, the deadline for the presentation is extended until the 15th day of the month following the corresponding quarter.

Given that the terms can be modified by the Tax Agency depending on the tax circumstances, we recommend that you be up to date on both the dates and the requirements established for the presentation of the model.

3. Where and how should it be presented?


Form 303 can be submitted electronically through the Electronic Headquarters of the Tax Agency or the mobile application of the Tax Agency. It can also be presented in paper format at their offices.

For electronic filing, it is necessary to have a digital certificate or an identification and authentication system that allows access to the Electronic Office of the Tax Agency.

It is important to take into account that the presentation of form 303 is mandatory online for those taxpayers who exceed certain billing limits or for those who pay taxes under a monthly refund system. On the other hand, for those who do not exceed these limits, the presentation can also be made in paper format.

In any case, it is advisable to use the telematic presentation of form 303, since it is faster, more comfortable and safer than filing on paper. In addition, the Tax Agency offers different online tools and services to facilitate the completion of the form and its electronic submission.

It is important to take into account that an incorrect or incomplete presentation can give rise to fines and sanctions by the Tax Agency. Therefore, it is essential that companies and the self-employed are well informed about tax obligations and have good control of their income and expenses.

To complete the 303 model, we must have a series of documents and records that support the commercial operations carried out during the quarter and that prove the VAT collected and the VAT paid. For example: Sales invoices, purchase invoices, receipts and other documents.

In addition to model 303, there are other tax forms that must be submitted in Spain.

For example, model 390 is an annual summary of the operations carried out during the fiscal year and model 347 is a form that is presented to declare operations with third parties that exceed 3.005,06 euros in the fiscal year.

In conclusion, model 303 is a fundamental tax form for the declaration and payment of VAT collected and borne in Spain.

It is important to comply with this tax obligation to avoid fines and penalties from the Tax Agency.

We recommend you to carry out a good control of income and expenses, file the documents correctly and have good tax advice that allows you to take advantage of opportunities and comply with all tax obligations in a timely manner.
