Is DIRT due on interest earned from a loan

I am wondering is DIRT due on interest earned from a loan?

For example Person (A) lends Person (B) €20,000. (B) pays back €30,000 to (A) over 3 years including interest of €10,000.
Does (A) pay DIRT on this €10,000 euro?

Thanks

No.

The borrower should withhold 20% tax and the lender will pay Income Tax at the marginal rate, PRSI and USC on the interest received.

Thanks for the reply. Forgive me if it's a stupid question but why would the borrower withold 20%? Thanks

Apologies for reviving a 10 year old thread but does anybody know if this is correct and can they provide any relevant Revenue/other links perhaps?

In particular, if the lender in this case was otherwise exempt from income tax (e.g. their gross tax was cancelled out by their tax credits) then why would 20% be withheld?
