An Inquiry into the Nature and Causes of the Wealth of Nations by Adam Smith

Secondly, land is a subject which cannot be removed; whereas stock easily may. The proprietor of land is necessarily a citizen of the particular country in which his estate lies. The proprietor of stock is properly a citizen of the world, and is not necessarily attached to any particular country. He would be apt to abandon the country in which he was exposed to a vexatious inquisition, in order to be assessed to a burdensome tax; and would remove his stock to some other country, where he could either carry on his business, or enjoy his fortune more at his ease. By removing his stock, he would put an end to all the industry which it had maintained in the country which he left. Stock cultivates land; stock employs labour. A tax which tended to drive away stock from any particular country, would so far tend to dry up every source of revenue, both to the sovereign and to the society. Not only the profits of stock, but the rent of land, and the wages of labour, would necessarily be more or less diminished by its removal.

The nations, accordingly, who have attempted to tax the revenue arising from stock, instead of any severe inquisition of this kind, have been obliged to content themselves with some very loose, and, therefore, more or less arbitrary estimation. The extreme inequality and uncertainty of a tax assessed in this manner, can be compensated only by its extreme moderation; in consequence of which, every man finds himself rated so very much below his real revenue, that he gives himself little disturbance though his neighbour should be rated somewhat lower.

By what is called the land tax in England, it was intended that the stock should be taxed in the same proportion as land. When the tax upon land was at four shillings in the pound, or at one-fifth of the supposed rent, it was intended that stock should be taxed at one-fifth of the supposed interest. When the present annual land tax was first imposed, the legal rate of interest was six per cent. Every hundred pounds stock, accordingly, was supposed to be taxed at twenty-four shillings, the fifth part of six pounds. Since the legal rate of interest has been reduced to five per cent. every hundred pounds stock is supposed to be taxed at twenty shillings only. The sum to be raised, by what is called the land tax, was divided between the country and the principal towns. The greater part of it was laid upon the country; and of what was laid upon the towns, the greater part was assessed upon the houses. What remained to be assessed upon the stock or trade of the towns (for the stock upon the land was not meant to be taxed) was very much below the real value of that stock or trade. Whatever inequalities, therefore, there might be in the original assessment, gave little disturbance. Every parish and district still continues to be rated for its land, its houses, and its stock, according to the original assessment; and the almost universal prosperity of the country, which, in most places, has raised very much the value of all these, has rendered those inequalities of still less importance now. The rate, too, upon each district, continuing always the same, the uncertainty of this tax, so far as it might he assessed upon the stock of any individual, has been very much diminished, as well as rendered of much less consequence. If the greater part of the lands of England are not rated to the land tax at half their actual value, the greater part of the stock of England is, perhaps, scarce rated at the fiftieth part of its actual value. In some towns, the whole land tax is assessed upon houses; as in Westminster, where stock and trade are free. It is otherwise in London.

In all countries, a severe inquisition into the circumstances of private persons has been carefully avoided.

At Hamburg, {Memoires concernant les Droits, tom. i, p.74} every inhabitant is obliged to pay to the state one fourth per cent. of all that he possesses; and as the wealth of the people of Hamburg consists principally in stock, this tax maybe considered as a tax upon stock. Every man assesses himself, and, in the presence of the magistrate, puts annually into the public coffer a certain sum of money, which he declares upon oath, to be one fourth per cent. of all that he possesses, but without declaring what it amounts to, or being liable to any examination upon that subject. This tax is generally supposed to be paid with great fidelity. In a small republic, where the people have entire confidence in their magistrates, are convinced of the necessity of the tax for the support of the state, and believe that it will be faithfully applied to that purpose, such conscientious and voluntary payment may sometimes be expected. It is not peculiar to the people of Hamburg.

The canton of Underwald, in Switzerland, is frequently ravaged by storms and inundations, and it is thereby exposed to extraordinary expenses. Upon such occasions the people assemble, and every one is said to declare with the greatest frankness what he is worth, in order to be taxed accordingly. At Zurich, the law orders, that in cases of necessity, every one should be taxed in proportion to his revenue; the amount of which he is obliged to declare upon oath. They have no suspicion, it is said, that any of their fellow citizens will deceive them. At Basil, the principal revenue of the state arises from a small custom upon goods exported. All the citizens make oath, that they will pay every three months all the taxes imposed by law. All merchants, and even all inn-keepers, are trusted with keeping themselves the account of the goods which they sell, either within or without the territory. At the end of every three months, they send this account to the treasurer, with the amount of the tax computed at the bottom of it. It is not suspected that the revenue suffers by this confidence. {Memoires concernant les Droits, tom. i p. 163, 167,171.}

To oblige every citizen to declare publicly upon oath, the amount of his fortune, must not, it seems, in those Swiss cantons, be reckoned a hardship. At Hamburg it would be reckoned the greatest. Merchants engaged in the hazardous projects of trade, all tremble at the thoughts of being obliged, at all times, to expose the real state of their circumstances. The ruin of their credit, and the miscarriage of their projects, they foresee, would too often be the consequence. A sober and parsimonious people, who are strangers to all such projects, do not feel that they have occasion for any such concealment.

In Holland, soon after the exaltation of the late prince of Orange to the stadtholdership, a tax of two per cent. or the fiftieth penny, as it was called, was imposed upon the whole substance of every citizen. Every citizen assesed himself, and paid his tax, in the same manner as at Hamburg, and it was in general supposed to have been paid with great fidelity. The people had at that time the greatest affection for their new government, which they had just established by a general insurrection. The tax was to be paid but once, in order to relieve the state in a particular exigency. It was, indeed, too heavy to be permanent. In a country where the market rate of interest seldom exceeds three per cent., a tax of two per cent. amounts to thirteen shillings and four pence in the pound, upon the highest neat revenue which is commonly drawn from stock. It is a tax which very few people could pay, without encroaching more or less upon their capitals. In a particular exigency, the people may, from great public zeal, make a great effort, and give up even a part of their capital, in order to relieve the state. But it is impossible that they should continue to do so for any considerable time; and if they did, the tax would soon ruin them so completely, as to render them altogether incapable of supporting the state.

The tax upon stock, imposed by the land tax bill in England, though it is proportioned to the capital, is not intended to diminish or, take away any part of that capital. It is meant only to be a tax upon the interest of money, proportioned to that upon the rent of land; so that when the latter is at four shillings in the pound, the former may be at four shillings in the pound too. The tax at Hamburg, and the still more moderate taxes of Underwald and Zurich, are meant, in the same manner, to be taxes, not upon the capital, but upon the interest or neat revenue of stock. That of Holland was meant to be a tax upon the capital.
