If you're considering selling Bitcoin or any other cryptocurrency for the first time, it's crucial to understand the tax implications of your sale.
In Ireland, like many other countries, the profit you make from selling Bitcoin may be subject to Capital Gains Tax (CGT).
Here's a beginner-friendly guide to help you navigate through the process.
What is Capital Gains Tax (CGT)?
Capital Gains Tax is a tax on the profit (or gain) you make when you sell, gift, or dispose of an asset that has increased in value. It's the gain you make that's taxed, not the total amount of money you receive. For cryptocurrencies like Bitcoin, CGT comes into play when you sell your digital currency for more than you paid for it.
How is CGT Calculated on Bitcoin Sales?
Calculating CGT on Bitcoin sales involves a few steps:
Determine the Gain: First, you need to calculate the gain you've made. This is the difference between what you sold your Bitcoin for and what you originally paid for it, including any associated costs like transaction fees.
Deduct Allowable Expenses: You can deduct certain costs associated with acquiring or selling your Bitcoin, such as fees or commissions paid to exchanges.
Apply the Annual Exemption: Each individual has an annual CGT exemption of €1,270. If your gain is less than this amount, you won't have to pay any CGT.
Calculate the Tax: If your gain exceeds the exemption, you'll pay CGT at a rate of 33% on the remaining amount.
Special Considerations for Bitcoin
Record-Keeping: It's essential to keep detailed records of your Bitcoin transactions, including dates, amounts, and the value of Bitcoin at the time of each transaction. This information will be crucial for accurately calculating your gain and any tax due.
Timing: The timing of your sale can significantly impact your CGT liability. Holding onto your Bitcoin for a longer period may affect the amount of tax you owe.
Losses: If you sell Bitcoin at a loss, you may be able to use this loss to offset gains from other investments, reducing your overall CGT liability.
When and How to Pay CGT
If you make a gain from the sale of Bitcoin between 1 January and 30 November, you must pay your CGT by 15th December in that same year. If you sell and make a gain in December, you must pay your CGT by the following 31st January. You can pay CGT through Revenue's myAccount or ROS services.
Filing a CGT return
A CGT return is due by the 31st of October in the year following the tax year in which you made the gain. For example, if you sell Bitcoin at a profit in 2023, your CGT would be due by October 31, 2024.
