Ask Audrey: Do I have to pay tax on my OnlyFans, tell me?

Ask Audrey has been sorting Cork people out for ages.
Hello it’s Rosealeen here in Ballydesmond. I was looking at your man Matty Gilbert on Instagram, for longer than would be considered pure by my cousin the nun, and her with a boyfriend. Matty is the Irish fella that makes a fortune on the OnlyFans website, sharing photos of himself topless.
On the one hand, it’s a sad reflection of the way society is going that a lad feels the need to share photos of himself in the semi-nip. On the other hand he makes 50 grand a month, so I registered there and put up a photo of myself in a Kerry jersey, because they’re fierce perverts over there across the border. Didn’t I make €12,000 in one hour. Do I have to pay tax on that, tell me?
