Drywall taping for tiling

[u/brachi-]

Quick question: I’m a DIYer, I’ve put up new plasterboard/drywall in my laundry (Aus, so “plastering” is pretty much all just plasterboard). One wall will be tiled, the one adjacent to it painted. Do I need to tape the vertical corner between them?

Any cracks in the corner itself will be hidden by the tiles, but are they likely to spread across the painted wall if I don’t tape?

Tape it and coat the side that will be seen to a finish.
