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.

What Taxes Do You Need to File

What we handle:

  • Capital Gains Tax on shares and funds
  • Deemed disposal on ETFs
  • Dividend income and withholding tax
  • Crypto disposals and gains
  • Combining investment income with your other Form 11 obligations (self-employed, rental, PAYE + extra income)

Note: we handle Capital Gains Tax as part of an existing Form 11 filing obligation, we don’t file standalone CG1 returns.

We give you the confidence that your return is correct, without the hassle of the Revenue’s Online System or the costly fees of an accountant. We’re proud to offer a 100% tax guarantee. * see Ts + Cs page.

FAQs About Online Saving in Ireland

Do I need to pay Irish tax on interest earned through Raisin?2026-03-13T10:03:39+00:00

Yes. If you are an Irish tax resident, you must declare all foreign savings interest, including interest earned through Raisin or other online platforms, on your Irish tax return.

Even though your savings are held with EU banks, Revenue still treats the interest as taxable income in Ireland.

FastTax.ie makes this easy by guiding you through exactly what to declare.

Why isn’t DIRT deducted automatically on Raisin accounts?2026-03-13T10:12:48+00:00

Irish banks deduct DIRT automatically before paying you interest.

However, when your savings are held with banks outside Ireland, DIRT is usually not deducted at source, and the responsibility falls on you to declare and pay the tax yourself.

This is normal and one of the common areas FastTax.ie helps customers with.

What tax rate applies to Raisin interest?2026-03-13T10:12:33+00:00

In most cases, interest from EU deposit accounts is taxed at the same rate as Irish DIRT, which is currently 33%.

If any foreign tax has already deducted a credit for this can be claimed for in your Irish tax return.

FastTax.ie ensures the correct tax is applied and helps avoid overpaying.

What is deemed disposal on ETFs?2026-09-30T14:08:27+01:00

ETFs held in Ireland are subject to an 8-year deemed disposal rule, meaning tax can become due even if you haven’t actually sold the fund. It’s one of the more commonly missed obligations for investors and we make sure it’s accounted for correctly.

Do I need to file a Form 11 if I only made a small crypto gain?2026-09-30T14:07:21+01:00

If you’ve disposed of crypto at a gain, it generally needs to be declared as part of your tax return, regardless of the amount. We can help you work out what applies to your situation.

How does FastTax.ie help Raisin savers?2026-05-21T23:39:57+01:00
