Yes. This is normal in all those countries with free easy tax filing. I regularly adjust the number, claiming various expenses etc. I have been audited twice, which was actually a lot less scary than it sounds. This is normal, easy and doesn’t cost and doesn’t even need complicated software. I have filled in forms, but I believe you can also do it online in the country I’m talking about now.
