Being a freelancer or managing an SME in Spain involves a myriad of responsibilities, and tax management is, without a doubt, one of the most critical. With an ever-evolving regulatory landscape, it's easy to make mistakes that can lead to penalties and complications. Here, we break down the most frequent tax errors and how to prevent them.
1. Incorrect Deduction of Expenses
One of the most common mistakes is confusing personal and professional expenses. The Tax Agency (AEAT) is strict: only expenses necessary for the economic activity and properly justified with an invoice are deductible. Errors such as deducting household utilities without applying the correct percentage of business use, or unjustified vehicle expenses, are common.
2. Inefficient VAT Management
Value Added Tax (VAT) is another source of errors. From applying incorrect VAT rates to mistakes in quarterly (Modelo 303) or annual (Modelo 390) declarations. It's also common to forget to apply the VAT pro-rata in mixed activities or to fail to submit settlements on time, leading to surcharges and penalties.
3. Errors in IRPF Withholdings
Many freelancers forget to apply withholdings on invoices issued to other professionals or companies, or apply an incorrect percentage. Similarly, failing to submit or submitting late the Modelo 111 (professional and employee withholdings) and Modelo 130 (quarterly IRPF payment) can lead to problems with the Tax Agency.
4. Non-Compliance with Tax Deadlines
Deadlines are non-negotiable. Forgetting the deadline for submitting quarterly (VAT, IRPF) or annual models (Income Tax return, Modelo 347, etc.) is a serious error that always results in surcharges or fines. It is essential to know the taxpayer's calendar and be proactive.
5. Lack of Awareness of New Regulations: VeriFactu and e-invoicing
The tax landscape is rapidly transforming. The Anti-Fraud Law and the VeriFactu system are the protagonists of tax digitalization. From January 1, 2027, for companies and July 1, 2027, for freelancers and micro-SMEs, the issuance of verifiable electronic invoices will be mandatory. Many freelancers are not yet prepared for this transition. It is crucial to understand when VeriFactu is mandatory and how it will affect their daily operations.
Preparation involves ensuring that your current management software has the necessary API VeriFactu or allows for proper ERP VeriFactu integration. For those using specific programs, it will be vital to know how to import Factusol to VeriFactu, or if they use other systems, how to import Sage 50 or import Holded. Even for those managing their finances with spreadsheets, the ability to import Excel to VeriFactu or the use of a VeriFactu gateway for software will be key aspects to ensure compliance.
