The importance of personal tax advisory during tax season

Tax season can be a stressful time for many individuals, especially those who are not familiar with the intricacies of the Portuguese tax system. Personal tax advisory provides expert guidance and support to navigate through the complexities of the tax season. By enlisting the services of a personal tax advisor, individuals can ensure that their tax returns are filed accurately and in compliance with all relevant regulations.

Essential documents required for personal tax advisory in Portugal

To ensure a smooth and efficient tax filing process, it is crucial to have all the necessary documents in order. Here are some key documents that you will need for personal tax advisory in Portugal:

  1. Identification documents: This includes your passport or ID card, as well as your taxpayer identification number (NIF).
  2. Income documents: You must provide documentation of all sources of income, including payslips, bank statements, and any income from investments or rental properties. In the case of financial portfolios, a record of all transactions on a FIFO basis identifying the prices and dates of sales and acquisitions for each asset is required.

Tips for organizing your personal tax documents

Organizing your personal tax documents is critical to a smooth and stress-free tax filing process. Here are some tips to help you stay organized:
