1. Overview of Portugal Crypto Tax 2025

🧾 1.1 Short‑Term vs Long‑Term Gains

Portugal officially ended its full crypto tax exemption in 2023. Now:

• Short-term gains (< 365 days) are taxed at a flat 28% under Category G, includes staking, lending, and sales/swaps within 1 year.
• Long-term gains (> 365 days) remain generally tax-exempt, unless assets resemble securities or involve non‑EEA counterparties.

This distinction is fundamental to Portugal crypto tax 2025 and shapes holding strategies.

🔄 1.2 Categories of Crypto Income

Portuguese tax rules divide crypto-derived income into three key categories:

• Category G (Capital Gains): Short-term disposals taxed at 28%, sales or swaps of coins held less than 365 days.
• Category E (Passive Income): Covers staking and lending rewards, also taxed at 28%.
• Category B (Business/Professional Income): Applies to business-like operations such as mining farms or frequent trading; taxed progressively (14.5–53%).

📊 1.3 Why It Matters for 2025 Planning

• Holding strategy: Holding assets for > 365 days becomes a powerful exemption tool under Portugal crypto tax 2025.
• Income delineation: Proper classification avoids misfiling and electoral tax brackets.
• Business vs Hobby: The line between casual and professional activity affects enormous tax implications.

📌 1.4 Key Filing & Compliance Overview

• Tax Form: Report crypto income with IRS Modelo 3, Attachment G for short-term, E for staking/lending, B for business activities.
• Deadlines: Submit between April 1 – June 30, pay due by August 31.
• Record-Keeping: Maintain timestamps, EUR valuations, and holding-period proof for exemptions.

• Be cautious: this exemption excludes tokens considered “security-like” or held with non-EEA providers.

🔁 4.2 Use Crypto-to-Crypto Swaps to Defer Taxes

💼 4.4 Optimize Classification: Passive vs Professional

• Keep profit motives low—avoid frequent trades or large-scale mining operations to minimize risk of being classified as a professional business.

🧾 4.5 Use Simplified Regime for Small-Scale Business
