Changes to VAT Filing Frequency in Portugal for 2026:<\/p>\n
What Is Changing, How It Works, and How to Prepare<\/p>\n
Summary<\/p>\n
From 2026, several important changes to the frequency of VAT returns in Portugal will come into effect. The most relevant include: the end of automatic notifications from the Tax Authority, the responsibility placed on taxpayers to verify their previous year\u2019s turnover, and the obligation to submit a Change Declaration when applicable. The \u20ac650,000 turnover threshold becomes decisive. This article outlines what is changing,<\/p>\n
<\/p>\n
Main Article<\/p>\n
1. Legal context and purpose of the reform<\/p>\n
The measures introduced by Decree-Law No. 49\/2025 aim to simplify tax obligations and reduce administrative burden. Previously, the Tax Authority automatically informed each taxpayer of their VAT filing frequency. Under the new framework, that process ends taxpayers are now responsible for determining and updating their own VAT periodicity.<\/p>\n
<\/p>\n
2. What has changed?<\/p>\n
a) Taxpayers now take the initiative<\/p>\n
The Tax Authority no longer updates the filing frequency automatically. Businesses must verify their turnover and update their VAT regime through a Change Declaration where required.<\/p>\n
b) The \u20ac650,000 threshold<\/p>\n
Turnover for 2025 determines the applicable frequency for 2026:<\/p>\n
\u00b7 \u2265 \u20ac650,000 \u2192 mandatory monthly filing<\/p>\n
\u00b7 < \u20ac650,000 \u2192 quarterly filing is allowed; monthly filing remains optional<\/p>\n
c) Change Declaration to be submitted in January 2026<\/p>\n
Any required change must be formalised via a Change Declaration submitted only during January 2026, taking effect from 1 January 2026.<\/p>\n
d) End of the minimum three-year stay in the monthly regime<\/p>\n
The mandatory three-year permanence rule for the monthly regime has been abolished, providing greater flexibility.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
3. Practical examples<\/p>\n
<\/p>\n
Example 1: mandatory switch to monthly regime<\/p>\n
A quarterly filer exceeds \u20ac650,000 in turnover in 2025.<\/p>\n
\u2192 Must file a Change Declaration in January 2026.<\/p>\n
<\/p>\n
Example 2: optional switch to monthly regime<\/p>\n
A quarterly filer remains below \u20ac650,000.<\/p>\n
\u2192 May voluntarily opt for monthly filing.<\/p>\n
<\/p>\n
Example 3: mandatory continuation in monthly regime<\/p>\n
A monthly filer remains above the threshold.<\/p>\n
\u2192 Must stay in the monthly regime.<\/p>\n
<\/p>\n
Example 4: possibility of switching back to quarterly regime<\/p>\n
A monthly filer drops below \u20ac650,000.<\/p>\n
\u2192 Not required to switch but may do so if preferred.<\/p>\n
<\/p>\n
