or just FairTax without the "prebates."
I actually meant a fair tax, but said flat tax.
Flat tax? That's the whole premise of the Pay-As-You-Go system here (I assume America has a similar thing), but obviously people's tax payable is not just dependent on how much they make and even with such a system in place tax returns need to be filled out so that people can claim deductions.
There is a massive system overhaul that needs to be done, but a proper and fair tax system wouldn't work in a way to do the deductions like this. I am actually a huge proponent of a consumption based tax. You are taxed based on what you spend, not what you earn. The current US tax system is thousands of pages a laws and every individual is expected to know all of it, or face a penalty at the end of the year. Teh fact is that the current system has people so scared of screwing it up, or so confused, that they believe they are better off giving the government extra money all year and then getting it back in a zero interest refund. Of course, if you accidentally pay too little you have to pay it back, plus interest and penalties. And a large number of people don't realize just what things in their life save them money, because it is too daunting of a task. So often they don't even take all the deductions they should.
Straighten all that out and have it be a very simplified system and there will be greater government revenue as there will be less instances of fraud or error, thus less employees required to investigate it. Simplified also likely means less paperwork, so less supply cost to the government as well. The more complicated taxes get the more it costs government to collect taxes.
But back to your original point, now that I have more time.
What incentive would people have to complete a tax return if they know they're going to have to pay some of that out?
It is fiscally smarter to set up your taxes in a way that you have as little refund as possible, or even owe some. This drives my wife insane, as she loves that giant check every year, but I can do much better thinsg with my money over the year than let it sit in the Uncle Sam bank of zero interest savings account. Something like increase the amount I put toward my retirement fund. I mean, I could take a $1,500 refund check every single year, or I could already have put all of that $1,500 into my retirement fund (assuming all at the beginning with a one time annual interest rate growth in order to simplify the discussion) throughout the year where it could be gaining 2% interest in a year as bad as this (giving me an extra $30 at the end of the year) or as much as 20% interest in a booming economy (giving me an extra $300 at the end of the year).
So, what incentive is there to complete a return if I don't get a refund, and may even owe? Because over the past year I had more of my money not in government hands, and if used wisely, have even more money now.
