1. Charges on any publicly granted privileges, such as the exclusive right to use a portion of the frequency spectrum for radio and TV broadcasts.

2. Payments for extractions of natural resources. Such payments should be set at levels that yield the greatest possible revenue of the resources, in present value terms.

3. Taxes on pollution. Every individual or enterprise that pollutes the air, water or ground should be required to pay the estimated cost of the pollution it generates. The effect of pollution on the rental value of surrounding land is one possible measure of its cost.

4. Taxes on any other activities that reduce the rental value of surrounding land.

5. Taxes on activities such as driving or parking in crowded streets, where one person's activities reduce opportunities for others. The administration of such charges may be so expensive that it is not worth implementing them, but if the administration can be handled sufficiently cheaply, these charges are efficient to the extent that they only charge people for costs imposed on others.

6. Taxes on activities, such as the consumption of alcohol, which impose costs on others (e.g., higher traffic fatalities).

7. Charges for local public services, such as water, electricity, sewer connections, etc. It is not generally desirable to make every service completely self-financing. Rather, what is desirable is that each user be required to pay the marginal cost of the service he receives. Extensions of service networks are efficient when they increase publicly collected land rents by enough to cover the costs not covered by user charges.

8. A self-assessed tax on permanent improvements to land, at a very low rate (perhaps 1/10 of 1% per year). With a self-assessed tax, each possessor of land names a price at which he would be willing to part with the land he possesses (and any immovable improvements). He pays a tax proportional to the value he names, and anyone who wishes to may take over possession at that price. The value of such a tax is that it makes it much easier to assemble land for redevelopment, and to identify appropriate compensation when land is taken for public purposes.

All of the above taxes are positively beneficial and should be collected even if the revenue is not needed for public purposes. Any excess can be returned to the population on an equal per capita basis. If these attractive sources of revenue do not suffice to finance necessary public expenditures, then the least damaging additional tax would probably be a "poll tax," a uniform charge on all residents. If some residents are regarded to be incapable of paying such a tax, then the next most efficient tax is a proportional tax on income up to some specified amount. Then there is no disincentive effect for all persons who reach the tax limit. The next most efficient tax is a proportional tax on all income.

It is important not to tax the profits of corporations. Capital moves from where it is taxed to where it is not, until the same rate of return is earned everywhere. If the city refrains from taxing corporations they will invest more...  Read the whole article
