Shares, dividends, ETFs or crypto. We’ll handle the tax.
If you invest or trade, FastTax.ie files your Form 11 correctly, without the guesswork.
Whether you’re actively trading or just holding a few investments on the side, if any of these sound like you, we can help:
- You buy and sell shares, ETFs, or funds
- You hold crypto and have bought, sold, or swapped it this year
- You receive dividend income
- You’re not sure if “deemed disposal” applies to you
- You’ve never filed a Form 11 before and investing income is why you need to
Who needs to file a Form 11 for investment income?
Investment income doesn’t come with a clear instruction manual. Between capital gains, deemed disposal on ETFs every 8 years, dividend withholding tax, and new reporting rules for crypto exchanges, it’s easy to feel like you’re guessing or worse, that you’ve already gotten something wrong without knowing it.
That’s exactly where we come in. We don’t give investment advice, and we’re not here to tell you what to buy or sell. We make sure what you’ve already earned is filed correctly, so you can stop wondering and get it done for another year.
New rules to know about
From 1 January 2026, crypto exchanges are required to report to Revenue under new OECD CARF rules. If you’ve bought, sold, or swapped crypto, now is a good time to make sure your filing history is accurate and up to date.
