The thing is that many people have other sources of income that are not paychecks. Thus why most people need to do this yearly declarations. But it is true that in any modern country this declarations are pre-made by tax agencies and it’s easier to fill.
And there’s also deductions. In many countries people can get tax deductions by many reasons and in most places you need to manually ask for them and fill the requirements.
Here for instance we can deduct money paid to Unions from our taxes. As political and syndicate afiliation is protected by law those payments are not automatically reported to the tax agency so if you paid them you have to manually fill the tax return.
That’s how I suppose it works in every country.
