What happens to my dividend if I trade online?

I recently opened an execution only share trading account with Davy and made my first purchase.

The share I purchased goes ex dividend next month.

Do I have to do anything to collect this dividend or does the dividend follow my share purchase to my Davy Account?

It'll automatically arrive in your cash balance in the Davy account once it's paid.

... and remember you need to disclose dividend income to Revenue as part of your returns. You may already know this, but just in case...

I think Davy will report it in any case, along with the DWT they deducted and remitted to Revenue
