Terms & Conditions

Effective Date: October 2025
Last Updated: October 2025

Welcome to CG1 Helper (“we,” “us,” “our”). By using this website, you agree to the following terms. Please read them carefully before proceeding.

1. Purpose

CG1 Helper is an informational tool that helps users prepare figures for the Irish Revenue CG1 Capital Gains Tax form. It automates FX conversions and related calculations based on data you upload. It is not a substitute for professional tax advice.

2. Use of Service

The service is provided for personal, non-commercial use.

You agree to use it lawfully and not upload files containing malicious code or unrelated personal data.
You are responsible for ensuring that your uploaded data (for example, eToro exports) is correct and complete.

3. No Financial or Tax Advice

All calculations and summaries are provided for general guidance only. We do not guarantee accuracy or completeness and accept no liability for errors or omissions. For official tax filings, you should consult a qualified tax professional.

4. Legal Status

CG1 Helper is not a financial services provider, investment intermediary, or tax agent as defined under Irish or EU law. The service does not hold authorisation from the Central Bank of Ireland and does not provide any regulated financial service. CG1 Helper does not submit, file, or communicate any information to Irish Revenue on your behalf. All calculations are automated outputs based solely on the data you upload.

5. FX Conversion

CG1 Helper automatically applies a USD → EUR foreign-exchange (FX) rate when processing your file.

For prior years, the official Revenue annual FX rate is used.
For the current year, you may choose to apply the provisional European Central Bank (ECB) average rate until Revenue publishes its official rate.
FX rates are applied consistently, but users remain responsible for verifying accuracy and selecting the appropriate option.

6. Bed & Breakfast (B&B) Rule

Where selected, CG1 Helper applies the Revenue “Bed & Breakfast” 30-day rule, which restricts the use of losses if the same asset is repurchased within 30 days. This adjustment is applied automatically using transaction dates and instrument identifiers in your uploaded file.

7. Outputs & Accuracy

Generated reports and CG1 forms are produced based on the data and options you provide. Every effort is made to ensure accuracy, but CG1 Helper cannot guarantee that outputs will be free of error or suitable for every individual circumstance. You remain responsible for reviewing all figures before filing with Revenue.

8. Scope & Limitations

CG1 Helper currently supports eToro statements and processes only the “Closed Positions” sheet, which contains completed trades.
The tool does not calculate FX gains or losses on deposits or withdrawals.
All calculations are based on realised trading data contained in the uploaded file.
For eToro accounts with a base currency in euro, trades are still executed and settled in US dollars within the platform. CG1 Helper therefore uses the USD-based results reported by eToro and converts them to euro using official annual exchange rates published by the Irish Revenue Commissioners or, where applicable, the European Central Bank.
The service may not account for all possible tax scenarios, reliefs, elections, or Revenue interpretations applicable to individual circumstances.
Support for additional brokers will be added in future versions of CG1 Helper.

9. Data Privacy & File Handling

Uploaded files are processed securely within encrypted cloud infrastructure.
Files are stored only temporarily to generate your results and are not retained permanently.
We do not require personal details to process your file.
If you purchase a promo code or redeem one linked to a purchase, we securely store your email address together with the promo code for validation, entitlement management, and limited account-related communication.
This information is not used for marketing and is never shared with third parties.
Messages submitted through the contact form are transmitted securely and used solely to respond to your enquiry.

10. Promo Codes

Promo codes may be offered as part of purchases or limited promotions.
They are non-transferable, have no cash value, and may be changed or withdrawn at any time.
Where linked to a purchase, codes are tied to the purchaser’s email address for validation.

11. User Responsibility

You are solely responsible for verifying all results and ensuring compliance with Irish Revenue reporting obligations. You agree not to rely exclusively on CG1 Helper when completing any official tax filing and to confirm all figures with Revenue or a qualified tax adviser before submission. If you believe an output contains an error, you agree to notify us promptly and allow us a reasonable opportunity to investigate and correct it.

12. Limitation of Liability

To the fullest extent permitted by law, CG1 Helper, its owners, and contributors shall not be liable for any direct, indirect, incidental, or consequential loss, including loss of profits, tax underpayments, penalties, or interest arising from use of this website or reliance on its outputs.

All use is at your own risk. You agree that any claim shall be limited to the amount (if any) paid by you for access to the service in the 12 months preceding the event giving rise to the claim. If you used the service free of charge, no liability shall apply.

13. Intellectual Property

All text, design, code, and graphics on this site are the property of CG1 Helper. You may not copy, distribute, or reproduce any part of the site without prior written permission.

14. Updates to These Terms

We may update these terms from time to time. Continued use of the site after any update signifies acceptance of the revised terms.

15. Governing Law

These Terms and any dispute arising from them shall be governed by and construed in accordance with the laws of Ireland. The courts of Ireland shall have exclusive jurisdiction to resolve any dispute relating to your use of this website or its services.

16. Beta Disclaimer

CG1 Helper is currently provided as a beta version. Functions and calculations may change without notice. Outputs are for demonstration and educational purposes only and may not reflect the most recent Revenue guidance. Users should verify all results independently.

Tax Calculation Options

These settings affect how CGT is calculated for the selected tax year.

Use ECB provisional FX rate (year being processed)

Revenue publishes the official annual FX rate for each tax year in February of the following year.
If enabled, CG1 Helper uses the ECB annual average where the official Revenue rate is not yet available.
When filing a final return, the published Revenue annual FX rate should be used.

Exclude Irish-domiciled ETFs from CGT totals

Irish-domiciled ETFs are subject to Exit Tax (41%), not standard CGT (33%), and do not fall within the CG1 reporting framework.
If enabled, CG1 Helper excludes these transactions from CGT totals but retains them in the Excel report for separate ETF / Exit Tax processing outside this tool.
If not enabled, CG1 Helper will treat these transactions under standard CGT rules.

Apply Revenue Bed & Breakfast rule

The Revenue “Bed & Breakfast” rule restricts losses where the same asset is repurchased within 30 days.
If enabled, CG1 Helper applies this 30-day loss restriction automatically.
If not enabled, disposals are treated under standard CGT matching rules.

Use prior-year B&B carryforward (requires B&B)

Only relevant if B&B applied in a prior year.
Requires upload of a prior CG1 Helper workbook containing the BnbCarryforward sheet.

CGT payments already made (Dec / Jan)

Enter any prior CGT payments already made.
The final balance or overpayment will adjust automatically in the summary and, where required, within the Self Assessment section.
