Switching to IPTV changes how television reaches your house. It does not automatically change your TV licence obligation. That's the honest headline, and the details are worth getting from the right source.
What the licence attaches to
Ireland's TV licence rules are written around the equipment in your home rather than around who supplies your programmes. That's why the obligation existed identically for aerial houses and dish houses, and why a change of supplier, to IPTV or anything else, isn't in itself the thing that decides your case. The definitions in the current rules do.
Why we won't give you a yes or no
Because the definitions genuinely carry the answer, and they're the State's to write and update, not ours. A provider's blog telling you exactly what your obligation is would be doing you a disservice the moment the rules moved. What we can tell you is where the answer lives: the official TV licence service publishes the current requirements and the current fee, and that page outranks anything written here.
The practical position for most households
Most Irish households switching to IPTV keep everything else about their setup: same telly in the sitting room, same habits, different plumbing. For them, the sensible assumption is that the licence position doesn't change just because the supplier did. If your setup is unusual, screens without receiving equipment, no television set at all, check the definitions directly rather than guessing in either direction.
Budget honestly
When you're totting up what cutting the cord saves, our advice is to keep the licence in the sums until you've confirmed otherwise from the official source. Comparing an IPTV plan at €12 a month against a bundle is already a comfortable comparison; it doesn't need optimistic accounting to win.
