Taxes may be able to be decreased (if it was made so simple, more people would do it) if there was a method of payment by tax ID/ or some number tied to both a person and a number for a business. People would just pay workers and perhaps even pay for products and services by going to a computer and transferring funds to the number for the person or business. This would automatically deduct the proper taxes and put the rest of the money in a bank account (or equivalent, like a monthly check mailed out for a person that doesn't subscribe online). The idea is that if paying taxes is simpler, less unintentional evasion would take place. If I don;t know how to do it very well, how can I expect a majority of the nation to?

This would impact banks and credit card companies.

Do credit card companies have too much influence? If you do not use two credit cards at east once a year, your credit score is damaged and it becomes harder to get loans for homes. What is a better way to determine if people will pay bills and mortgage payments? If there was that account number that deducted taxes, maybe certain things, such as a mortgage, utilities, car payments (but not subscriptions for ring tones [or ringtones?]) could be set up to autopay.
