Common Tax Mistakes Made by Freelancers in 2025: What You Should Avoid

Here’s the translation into American English:

The online advisory service for freelancers, Tax&Go, has presented a comprehensive analysis of the most common tax errors persisting in 2025, despite advancements in digitalization. This report highlights that a lack of document control, late tax filings, and improper expense deductions are recurring issues that severely impact freelancers, resulting in strict penalties and significant financial losses.

Tax&Go has analyzed internal data indicating that these errors occur across a wide variety of sectors, from e-commerce to professional services. Thanks to its digital approach, the firm can identify patterns and propose effective solutions that combine technology with ongoing monitoring.

Among the most frequent errors is the delay in submitting self-assessments. Despite the use of digital invoicing tools, there remains a gap between the issuance of documents and their proper accounting, which can lead to penalties of up to 20% of the owed amount, in addition to interest. To mitigate this risk, Tax&Go suggests automating accounting processes and establishing alerts that integrate tax generation with the fiscal calendar.

Another recurring issue is the failure to retain documentation for the legally required period, which is at least four years. Many freelancers do not have an organized digital filing system, complicating responses to requests from the Tax Agency. In this regard, the advisory service recommends using cloud storage solutions to facilitate access to documentation from any device at any time.

Improper expense deductions are also a common error. Ignorance about which expenses are deductible leads many freelancers to include personal expenses in their declarations or to inadequately justify certain expenses. To avoid this situation, Tax&Go emphasizes the importance of ongoing advice to review each tax item.

Additionally, the lack of adaptation of tax obligations to changes in business activity can result in over-taxation or non-compliance with obligations. The firm highlights that having a digital advisor allows for timely identification of when a transition in tax regime is necessary.

Lastly, Tax&Go warns that failing to take advantage of available deductions and bonuses is a common error that often goes unnoticed due to lack of knowledge. The advisory service includes a module that automatically alerts about applicable deductions, preventing the loss of important tax opportunities.

The combination of technology and human advisory is key in preventing tax errors, according to Tax&Go. Their entirely online model, offering a flat monthly fee covering tax, accounting, and legal management, removes the need for in-person visits. Clients simply upload their invoices, and the platform handles processing and generating taxes, with additional review by a specialized team.

In a context characterized by the growth of remote work and the proliferation of digital businesses, Tax&Go has adjusted its offerings to meet the new demands of freelance work, prioritizing immediacy and flexibility. Preventing tax errors not only avoids penalties but also contributes to better planning and allows for freeing up resources for investment and business growth.
