In 2025, despite the significant advances in digitization, the self-employed continue to face tax challenges that jeopardize their economic stability. A recent report from the online advisory service for self-employed professionals, Tax&Go, highlights the most frequent tax errors, revealing persistent flaws in document control, late filing of tax returns, and improper deduction of expenses. These problems, common in a variety of sectors such as e-commerce and professional services, entail severe penalties and economic losses.
The data from Tax&Go indicate that self-assessments filed after the deadline are a common mistake. Although digital invoicing tools have become popular, the gap between the issuance of documents and their proper accounting results in penalties that can reach 20% of the outstanding debt, in addition to interest. The advisory service emphasizes process automation and the use of integrated alerts to prevent these oversights, thereby acquiring rigorous control over tax deadlines.
The retention of documentation for a minimum of four years also emerges as a critical issue. Without an organized digital file, the self-employed are at a disadvantage when facing requests from the Tax Agency. Tax&Go recommends the use of cloud storage solutions, ensuring fast and efficient access to all relevant documentation from any device.
A third significant error is the improper deduction of expenses. The confusion about which expenses are deductible leads to frequent mistakes, such as the inclusion of personal expenses or the inadequate justification of certain expenditures. Here, ongoing guidance is crucial to review each entry and confirm its deductibility, thereby minimizing errors that could have negative tax implications.
Failing to adjust taxation to changes in economic activity can lead to overtaxation or non-compliance with obligations. By using a digital advisor, Tax&Go provides up-to-date data and automated analyses that enable the identification of the need to change the tax regime, avoiding unpleasant surprises at the end of the month.
Finally, the failure to take advantage of deductions and credits due to lack of knowledge implies missing out on significant tax opportunities. Tax&Go incorporates a module that alerts users about the applicable deductions, thereby optimizing their tax situation.
Tax&Go's strategy combines technology and human advisory, offering a fully online model with a flat monthly fee that covers tax, accounting and legal management. The platform allows customers to upload their invoices to process them and manage tax generation, with an additional review by the team, eliminating the need for physical travel.
As remote work and digital businesses continue to expand, Tax&Go adapts to the new realities of self-employment, prioritizing immediacy and flexibility. Preventing tax errors not only avoids penalties but also improves planning and frees up resources to invest and grow the business.
