UK Taxpayer ROI rental income paid into ROI account

[Lychees]

I have a client who is a UK taxpayer who has just let his second home in Ireland and the rental income is being paid into his Irish bank account. I assume that he will have to declare any profit in his UK tax return but at what exchange rate?

Also, if the income remains in Ireland, does he have to complete an Irish tax return? Does he only have to declare the income in the UK if the rental income is repatriated?

If resident and domiciled in the UK, your client has to declare his worldwide income in his UK tax return, whether or not it is remitted to the UK. He may well have to declare the property income in Ireland as well, and thus become involved in double taxation relief. But wait for other posts, as I am not an expert on this.

Exchange rate - in strictness the spot rate when each payment of rent is received. In practice HMRC shouldn't mind an average for the year as long as it is reasonable and hasn't fluctuated wildly.
