Welcome to CG1 Helper
CG1 Helper simplifies Capital Gains Tax calculations for the Irish Revenue CG1 form. Upload your broker file, let us crunch the numbers, and download a ready-to-use Excel report.
Designed initially for eToro users, CG1 Helper takes the complexity out of figuring out your liabilities when copytrading or managing the multitude of transactions, all of which are reported in USD and require correct FX conversion.
Key features include:
- Applies the Revenue Bed & Breakfast rule (30-day rule)
- Uses the official Revenue FX rate or ECB provisional rate
- Allows for losses carried forward from previous years
- Handles large volumes of trading transactions
- Creates a CG1-ready Excel report suitable for Revenue audits
How it works:
- Upload your eToro Excel export (other brokers coming soon)
- Apply your options (e.g. exemptions, B&B rule, previous years’ losses)
- Download your completed report to help file your CG1
🔒 Your file is processed securely, and data may be stored only for a short period to generate results. We do not need or collect any personal details from you. Nothing is stored permanently.
