Hey, it's FA here. Just wanted to chime in and say I totally agree with both colleagues. The only extra thing to think about is how much time the whole process eats up I mean from the very start to finish. It's not just the back and forth between the tax office and your employer, it’s also getting all your ducks in a row, prepping, and figuring out the right variation amount. Basically, you're trying to guess your income and deductions before they even happen. And honestly, depending on your job or your investments, that can get a bit rticky to nail down.
