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

by Adam Smith

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.

Taxes upon the Profit of particular Employments.

In some countries, extraordinary taxes are imposed upon the profits of stock; sometimes when employed in particular branches of trade, and sometimes when employed in agriculture.

Of the former kind, are in England, the tax upon hawkers and pedlars, that upon hackney-coaches and chairs, and that which the keepers of ale-houses pay for a licence to retail ale and spiritous liquors. During the late war, another tax of the same kind was proposed upon shops. The war having been undertaken, it was said, in defence of the trade of the country, the merchants, who were to profit by it, ought to contribute towards the support of it.

A tax, however, upon the profits of stock employed in any particular branch of trade, can never fall finally upon the dealers (who must in all ordinary cases have their reasonable profit, and, where the competition is free, can seldom have more than that profit), but always upon the consumers, who must be obliged to pay in the price of the goods the tax which the dealer advances; and generally with some overcharge.
