Sure it will never happen but here are my thoughts(starts handing out rotten tomatoes and fruit)
All goods and services are taxed at 45%, states are allowed 5% sales tax on top of that but no more, all income and property taxes end with property tax traded for a vehicle tax, the only people that have to fill out forms is those that become a business and sell goods or services regularly(monthly). Auction or used item sites like ebay and amazon they can easily be charged 45% on what they charge for users to sell items, sense there is a tax on the fee itself the sell of the item through the site should not be taxed as the item has already paid a tax on it once already.
Distribution
County’s get 1%
Citys get 9%
States get15%
Fed get 20%
Now if you reverse this order
Citys get 20%
County’s get 15%
States get 9%
Fed get 1%
city’s and counties would have so much money they could manage their populaces EASILY letting the fed get back to real issues like basic infrastructure and defense of the nation with cities being rich enough to handle disasters,health care and infrastructure. The futher you take moeny away from the palces that need it the less gets done to improve things.
THis also allows the cities to do some of the tax revue legwork making it cheaper to run the IRS.
———————————
Vehicles would be taxed based on gallons per mile at 29MPG or less its 5% yearly thats 50$ for every 1000 of blue book value if its a verifiable work vehicle its 0.1% or 1$ for every 1000 of blue book value.
At 30MPG or higher its 2% or 20$ per 1000 of blue book value, at 40MPG+ its 0.5 or 5$ per 1000 of blue book value, at 50+MPG its 0.1% or 1$ for every 1000 of blue book value .
Tractors,mowers and framing equipment are exempt,Any recreational vehicle would be taxed at 0.1% for tag processing.
All vehicles require a tag for identification out of date tags are fine for storage but you may be fined up to 5% of the total cost of the vehicle if you are caught without a tag, the tax you pay on the vehicle pays for the tag.
Edit
A recreational tag can be bought for any vehicle(muscle cars and antiques as well as 4X4) at the low tax rate but that vehicle is not street legal, one could create a law where if its 10-20 miles from either its trailer or garage its not a fineable offense but a warnable one.
Edit
This would replace property tax which is nothing more than government bullying you into paying to won your land, that or ensure those who make under 150K pay no property tax(it goes against their savings meaning gov will have to pay for them in the long run) or are over the age of 75…..but in all property taxes just need to be abolished…..
————————————————————-
Corporate would be under the same tax everything they buy or rent is hit with a 45% tax no costly tax code no loopholes just a straight tax on what is consumed and if the business employees people in the US you can subtract 0.0001%(or 1% per 1 thousand people in the taxable area thats city or county) from that up to 40%.
If a business employs a few thousand workers its worth it not to tax them in a consumer tax system.
============
For the poor
Now about the poor you can use the debit food stamp card system as tax exemption badge you that gets you tax off just about everything but rentals (car rentals are ok) this would be for those that make under 20K families or individuals. Now if that dose not quite work for individuals have it set up if you are in shcool you get the tax exemption if not and don’t have a kid or disability and make more than 12-16K a year then you just have to the the tax.
For families under 55K and under you get exemptions on food,gas(and utilities primarily power over 100$, water over 30$,sewer over 10$ and land line phone over 30) and purchase price of a vehicle but not the yearly tax that helps roads,pays for tags and acts as a sin tax against gas guzzlers.
If you have children in school or collage an exemption badge could be created to lower or remove the tax paid on some items for school, these could be put out like coupons in booklets that can be handed out during tax exempt drives or festivals the schools do to raise money for their individualize school.
==============
We have the technology to tax sales to take the burden off the common worker and the rich that get taxed coming and going even if the IRS dose not shrink in size a consumer tax just makes perfect sense.
