Think of Emergency Tax as the government’s overly cautious friend. When you start a new gig, your employer might not have your tax code yet. So, they slap on a default rate—usually 20% or 45%—just to be safe. It’s like ordering a salad but being charged for the entire buffet.
Merely because you forgot to hand in your P45 or tax form doesn’t mean you’re doomed. You’re actually owed that money back, and it’s just sitting in a government vault, waiting for you. Think of it as a forced savings plan, albeit a very annoying one.
