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.
2. "The tax which each individual is bound to pay ought to be certain and not arbitrary.
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.
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."
An equal land-tax, imposed indiscriminately and without any regard to the distinction of its quality, on all land cultivated, will raise the price of corn in proportion to the tax paid by the cultivator of the land of the worst quality. Lands of different quality, with the employment of the same capital, will yield very different quantities of raw produce. If on the land which yields a thousand quarters of corn with a given capital, a tax of 100l. be laid, corn will rise 2s. per quarter to compensate the farmer for the tax. But with the same capital on land of a better quality, 2,000 quarters may be produced, which at 2s. a quarter advance, would give 200l.; the tax, however, bearing equally on both lands will be 100l. on the better as well as on the inferior, and consequently the consumer of corn will be taxed, not only to pay the exigencies of the state, but also to give to the cultivator of the better land, 100l. per annum. during the period of his lease, and afterwards to raise the rent of the landlord to that amount. A tax of this description then would be contrary to the fourth maxim of Adam Smith, it would take out and keep out of the pockets of the people, more than what it brought into the treasury of the state. The taille in France before the Revolution, was a tax of this description; those lands only were taxed, which were held by an ignoble tenure, the price of raw produce rose in proportion to the tax, and therefore they whose lands were not taxed, were benefited by the increase of their rent. Taxes on raw produce as well as tithes are free from this objection: they raise the price of raw produce, but they take from each quality of land a contribution in proportion to its actual produce, and not in proportion to the produce of that which is the least productive.
From the peculiar view which Adam Smith took of rent, from his not having observed that much capital is expended in every country, on the land for which no rent is paid, he concluded that all taxes on the land, whether they were laid on the land itself in the form of land-tax or tithes, or on the produce of the land, or were taken from the profits of the farmer, were all invariably paid by the landlord, and that he was in all cases the real contributor, although the tax was in general, nominally advanced by the tenant. "Taxes upon the produce of the land," he says, "are in reality taxes upon the rent; and though they may be originally advanced by the farmer, are finally paid by the landlord. When a certain portion of the produce is to be paid away for a tax, the farmer computes as well as he can, what the value of this portion is, one year with another, likely to amount to, and he makes a proportionable abatement in the rent which he agrees to pay to the landlord. There is no farmer who does not compute before hand what the church tithe, which is a land-tax of this kind, is, one year with another, likely to amount to." It is undoubtedly true, that the farmer does calculate his probable outgoings of all descriptions, when agreeing with his landlord concerning the rent of his farm; and if for the tithe paid to the church, or for the tax on the produce of the land, he were not compensated by a rise in the relative value of the produce of his farm, he would naturally deduct them from his rent. But this is precisely the question in dispute: whether he will eventually deduct them from his rent, or be compensated by a higher price of produce. For the reasons which have been already given, I cannot have the least doubt but that they would raise the price of produce, and consequently that Adam Smith has taken an incorrect view of this important question.
Dr. Smith's view of this subject is probably the reason why he has described "the tithe, and every other land-tax of this kind, under the appearance of perfect equality, as very unequal taxes; a certain portion of the produce being in different situations, equivalent to a very different portion of the rent." I have endeavoured to shew that such taxes do not fall with unequal weight on the different classes of farmers or landlords, as they are both compensated by the rise of raw produce, and only contribute to the tax in proportion as they are consumers of raw produce. Inasmuch indeed as wages, and through wages, the rate of profits are affected, landlords, instead of contributing their full share to such a tax, are the class peculiarly exempted. It is the profits of stock, from which that portion of the tax is derived which falls on those labourers, who from the insufficiency of their funds, are incapable of paying taxes; this portion is exclusively borne by all those whose income is derived from the employment of stock, and therefore it in no degree affects landlords.
It is not to be inferred from this view of tithes, and taxes on the land and its produce, that they do not discourage cultivation. Every thing which raises the exchangeable value of commodities of any kind, which are in very general demand, tends to discourage both cultivation and production; but this is an evil inseparable from all taxation, and is not confined to the particular taxes of which we are now speaking.
This may be considered indeed as the unavoidable disadvantage attending all taxes received and expended by the state. Every new tax becomes a new charge on production, and raises natural price. A portion of the labour of the country which was before at the disposal of the contributor to the tax, is placed at the disposal of the state. This portion may become so large, that sufficient surplus produce may not be left to stimulate the exertions of those who usually augment by their savings the capital of the state. Taxation has happily never yet in any free country been carried so far as constantly from year to year to diminish its capital. Such a state of taxation could not be long endured; or if endured, it would be constantly absorbing so much of the annual produce of the country as to occasion the most extensive scene of misery, famine, and depopulation.
