But what is the standard situation?!
Unless someone (being an elderly and not tax savvy person) sees their exact situation and circumstances mirrored in such a notice, they'll probably still be none the wiser, and no more capable of working out their position. My impression is, people in general don't want to know or understand about these issues, they just want everything to be OK!
It's an awful pity the tax system wasn't more simple so people could easily figure it out. Why isn't there in this day and age a computer programe that one can log onto at revenue.ie and type in income and hey presto it calculates the tax, prsi, levies etc. Don't revenue have a system like that for themselves?
