An Inquiry into the Nature and Causes of the Wealth of Nations

by Adam Smith

1. The subjects of every state ought to contribute towards the support of the government, as nearly as possible, in proportion to their respective abilities; that is, in proportion to the revenue which they respectively enjoy under the protection of the state. The expense of government to the individuals of a great nation, is like the expense of management to the joint tenants of a great estate, who are all obliged to contribute in proportion to their respective interests in the estate. In the observation or neglect of this maxim, consists what is called the equality or inequality of taxation. Every tax, it must be observed once for all, which falls finally upon one only of the three sorts of revenue above mentioned, is necessarily unequal, in so far as it does not affect the other two. In the following examination of different taxes, I shall seldom take much farther notice of this sort of inequality; but shall, in most cases, confine my observations to that inequality which is occasioned by a particular tax falling unequally upon that particular sort of private revenue which is affected by it.

2. The tax which each individual is bound to pay, ought to be certain and not arbitrary. The time of payment, the manner of payment, the quantity to be paid, ought all to be clear and plain to the contributor, and to every other person. Where it is otherwise, every person subject to the tax is put more or less in the power of the tax-gatherer, who can either aggravate the tax upon any obnoxious contributor, or extort, by the terror of such aggravation, some present or perquisite to himself. The uncertainty of taxation encourages the insolence, and favours the corruption, of an order of men who are naturally unpopular, even where they are neither insolent nor corrupt. The certainty of what each individual ought to pay is, in taxation, a matter of so great importance, that a very considerable degree of inequality, it appears, I believe, from the experience of all nations, is not near so great an evil as a very small degree of uncertainty.

3. Every tax ought to be levied at the time, or in the manner, in which it is most likely to be convenient for the contributor to pay it. A tax upon the rent of land or of houses, payable at the same term at which such rents are usually paid, is levied at the time when it is most likely to be convenient for the contributor to pay; or when he is most likely to have wherewithall to pay. Taxes upon such consumable goods as are articles of luxury, are all finally paid by the consumer, and generally in a manner that is very convenient for him. He pays them by little and little, as he has occasion to buy the goods. As he is at liberty too, either to buy or not to buy, as he pleases, it must be his own fault if he ever suffers any considerable inconveniency from such taxes.

4. Every tax ought to be so contrived, as both to take out and to keep out of the pockets of the people as little as possible, over and above what it brings into the public treasury of the state. A tax may either take out or keep out of the pockets of the people a great deal more than it brings into the public treasury, in the four following ways. First, the levying of it may require a great number of officers, whose salaries may eat up the greater part of the produce of the tax, and whose perquisites may impose another additional tax upon the people. Secondly, it may obstruct the industry of the people, and discourage them from applying to certain branches of business which might give maintenance and employment to great multitudes. While it obliges the people to pay, it may thus diminish, or perhaps destroy, some of the funds which might enable them more easily to do so. Thirdly, by the forfeitures and other penalties which those unfortunate individuals incur, who attempt unsuccessfully to evade the tax, it may frequently ruin them, and thereby put an end to the benefit which the community might have received from the employment of their capitals. An injudicious tax offers a great temptation to smuggling. But the penalties of smuggling must arise in proportion to the temptation. The law, contrary to all the ordinary principles of justice, first creates the temptation, and then punishes those who yield to it; and it commonly enhances the punishment, too, in proportion to the very circumstance which ought certainly to alleviate it, the temptation to commit the crime. {See Sketches of the History of Man page 474, and Seq.} Fourthly, by subjecting the people to the frequent visits and the odious examination of the tax-gatherers, it may expose them to much unnecessary trouble, vexation, and oppression; and though vexation is not, strictly speaking, expense, it is certainly equivalent to the expense at which every man would be willing to redeem himself from it. It is in some one or other of these four different ways, that taxes are frequently so much more burdensome to the people than they are beneficial to the sovereign.

The evident justice and utility of the foregoing maxims have recommended them, more or less, to the attention of all nations. All nations have endeavoured, to the best of their judgment, to render their taxes as equal as they could contrive; as certain, as convenient to the contributor, both the time and the mode of payment, and in proportion to the revenue which they brought to the prince, as little burdensome to the people. The following short review of some of the principal taxes which have taken place in different ages and countries, will show, that the endeavours of all nations have not in this respect been equally successful.

ARTICLE I.—Taxes upon Rent—Taxes upon the Rent of Land.

A tax upon the rent of land may either be imposed according to a certain canon, every district being valued at a curtain rent, which valuation is not afterwards to be altered; or it may be imposed in such a manner, as to vary with every variation in the real rent of the land, and to rise or fall with the improvement or declension of its cultivation.

A land tax which, like that of Great Britain, is assessed upon each district according to a certain invariable canon, though it should be equal at the time of its first establishment, necessarily becomes unequal in process of time, according to the unequal degrees of improvement or neglect in the cultivation of the different parts of the country. In England, the valuation, according to which the different counties and parishes were assessed to the land tax by the 4th of William and Mary, was very unequal even at its first establishment. This tax, therefore, so far offends against the first of the four maxims above mentioned. It is perfectly agreeable to the other three. It is perfectly certain. The time of payment for the tax, being the same as that for the rent, is as convenient as it can be to the contributor. Though the landlord is, in all cases, the real contributor, the tax is commonly advanced by the tenant, to whom the landlord is obliged to allow it in the payment of the rent. This tax is levied by a much smaller number of officers than any other which affords nearly the same revenue. As the tax upon each district does not rise with the rise of the rent, the sovereign does not share in the profits of the landlord’s improvements. Those improvements sometimes contribute, indeed, to the discharge of the other landlords of the district. But the aggravation of the tax, which this may sometimes occasion upon a particular estate, is always so very small, that it never can discourage those improvements, nor keep down the produce of the land below what it would otherwise rise to. As it has no tendency to diminish the quantity, it can have none to raise the price of that produce. It does not obstruct the industry of the people; it subjects the landlord to no other inconveniency besides the unavoidable one of paying the tax. The advantage, however, which the land-lord has derived from the invariable constancy of the valuation, by which all the lands of Great Britain are rated to the land-tax, has been principally owing to some circumstances altogether extraneous to the nature of the tax.

It has been owing in part, to the great prosperity of almost every part of the country, the rents of almost all the estates of Great Britain having, since the time when this valuation was first established, been continually rising, and scarce any of them having fallen. The landlords, therefore, have almost all gained the difference between the tax which they would have paid, according to the present rent of their estates, and that which they actually pay according to the ancient valuation. Had the state of the country been different, had rents been gradually falling in consequence of the declension of cultivation, the landlords would almost all have lost this difference. In the state of things which has happened to take place since the revolution, the constancy of the valuation has been advantageous to the landlord and hurtful to the sovereign. In a different state of things it might have been advantageous to the sovereign and hurtful to the landlord.

As the tax is made payable in money, so the valuation of the land is expressed in money. Since the establishment of this valuation, the value of silver has been pretty uniform, and there has been no alteration in the standard of the coin, either as to weight or fineness. Had silver risen considerably in its value, as it seems to have done in the course of the two centuries which preceded the discovery of the mines of America, the constancy of the valuation might have proved very oppressive to the landlord. Had silver fallen considerably in its value, as it certainly did for about a century at least after the discovery of those mines, the same constancy of valuation would have reduced very much this branch of the revenue of the sovereign. Had any considerable alteration been made in the standard of the money, either by sinking the same quantity of silver to a lower denomination, or by raising it to a higher; had an ounce of silver, for example, instead of being coined into five shillings and two pence, been coined either into pieces which bore so low a denomination as two shillings and seven pence, or into pieces which bore so high a one as ten shillings and four pence, it would, in the one case, have hurt the revenue of the proprietor, in the other that of the sovereign.
