THE FUTURE OF MONEY Bernard A. Lietaer - library.uniteddiversity ...

The US went one step further by having the IRS rule that any
income in Time Dollars is automatically tax-exempt.
Strongly supportive
What this would involve is to provide systematic funding for
complementary currency initiatives that provide better social results
at a lower governmental cost. This would include funding the startup
of complementary currency systems and all the other Features
described in the 'mildly supportive' policy.
The Japanese go beyond that with their healthcare system, and in
regional development based on 'eco-money' projects. The Japanese
government is completely funding eco-money activities and is
considering paying for the accounting and clearing systems for
Healthcare Time Accounts. They justify it because it reduces the need
for other yen-based expenses, and provides a better service as well.
Besides automatic tax-exemption for income in complementary
currency as is the case for Time Dollars in the US, the most
productive tax incentive would be one that gives an incentive for
professionals and businesses to accept complementary currencies.
Such an incentive would increase the quality and diversity of services
and goods becoming available in complementary currencies. As most
complementary currency systems are already set up as non-profit
membership organisations, one could simply allow businesses to
treat complementary currency income as a contribution to a nonprofit
organisation. Community Way, a multimillion-dollar project in
Vancouver, Canada, is currently experimenting with this approach,
using smart cards to deal with the complementary currency
component.
