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

by Adam Smith

When, instead either of a certain portion of the produce of land, or of the price of a certain portion, a certain sum of money is to be paid in full compensation for all tax or tythe; the tax becomes, in this case, exactly of the same nature with the land tax of England. It neither rises nor falls with the rent of the land. It neither encourages nor discourages improvement. The tythe in the greater part of those parishes which pay what is called a modus, in lieu of all other tythe is a tax of this kind. During the Mahometan government of Bengal, instead of the payment in kind of the fifth part of the produce, a modus, and, it is said, a very moderate one, was established in the greater part of the districts or zemindaries of the country. Some of the servants of the East India company, under pretence of restoring the public revenue to its proper value, have, in some provinces, exchanged this modus for a payment in kind. Under their management, this change is likely both to discourage cultivation, and to give new opportunities for abuse in the collection of the public revenue, which has fallen very much below what it was said to have been when it first fell under the management of the company. The servants of the company may, perhaps, have profited by the change, but at the expense, it is probable, both of their masters and of the country.

Taxes upon the Rent of Houses.

The rent of a house may be distinguished into two parts, of which the one may very properly be called the building-rent; the other is commonly called the ground-rent.

The building-rent is the interest or profit of the capital expended in building the house. In order to put the trade of a builder upon a level with other trades, it is necessary that this rent should be sufficient, first, to pay him the same interest which he would have got for his capital, if he had lent it upon good security; and, secondly, to keep the house in constant repair, or, what comes to the same thing, to replace, within a certain term of years, the capital which had been employed in building it. The building-rent, or the ordinary profit of building, is, therefore, everywhere regulated by the ordinary interest of money. Where the market rate of interest is four per cent. the rent of a house, which, over and above paying the ground-rent, affords six or six and a-half per cent. upon the whole expense of building, may, perhaps, afford a sufficient profit to the builder. Where the market rate of interest is five per cent. it may perhaps require seven or seven and a half per cent. If, in proportion to the interest of money, the trade of the builders affords at any time much greater profit than this, it will soon draw so much capital from other trades as will reduce the profit to its proper level. If it affords at any time much less than this, other trades will soon draw so much capital from it as will again raise that profit.

Whatever part of the whole rent of a house is over and above what is sufficient for affording this reasonable profit, naturally goes to the ground-rent; and, where the owner of the ground and the owner of the building are two different persons, is, in most cases, completely paid to the former. This surplus rent is the price which the inhabitant of the house pays for some real or supposed advantage of the situation. In country houses, at a distance from any great town, where there is plenty of ground to chuse upon, the ground-rent is scarce anything, or no more than what the ground which the house stands upon would pay, if employed in agriculture. In country villas, in the neighbourhood of some great town, it is sometimes a good deal higher; and the peculiar conveniency or beauty of situation is there frequently very well paid for. Ground-rents are generally highest in the capital, and in those particular parts of it where there happens to be the greatest demand for houses, whatever be the reason of that demand, whether for trade and business, for pleasure and society, or for mere vanity and fashion.

A tax upon house-rent, payable by the tenant, and proportioned to the whole rent of each house, could not, for any considerable time at least, affect the building-rent. If the builder did not get his reasonable profit, he would be obliged to quit the trade; which, by raising the demand for building, would, in a short time, bring back his profit to its proper level with that of other trades. Neither would such a tax fall altogether upon the ground-rent; but it would divide itself in such a manner, as to fall partly upon the inhabitant of the house, and partly upon the owner of the ground.

Let us suppose, for example, that a particular person judges that he can afford for house-rent all expense of sixty pounds a-year; and let us suppose, too, that a tax of four shillings in the pound, or of one-fifth, payable by the inhabitant, is laid upon house-rent. A house of sixty pounds rent will, in that case, cost him seventy-two pounds a-year, which is twelve pounds more than he thinks he can afford. He will, therefore, content himself with a worse house, or a house of fifty pounds rent, which, with the additional ten pounds that he must pay for the tax, will make up the sum of sixty pounds a-year, the expense which he judges he can afford, and, in order to pay the tax, he will give up a part of the additional conveniency which he might have had from a house of ten pounds a-year more rent. He will give up, I say, a part of this additional conveniency; for he will seldom be obliged to give up the whole, but will, in consequence of the tax, get a better house for fifty pounds a-year, than he could have got if there had been no tax for as a tax of this kind, by taking away this particular competitor, must diminish the competition for houses of sixty pounds rent, so it must likewise diminish it for those of fifty pounds rent, and in the same manner for those of all other rents, except the lowest rent, for which it would for some time increase the competition. But the rents of every class of houses for which the competition was diminished, would necessarily be more or less reduced. As no part of this reduction, however, could for any considerable time at least, affect the building-rent, the whole of it must, in the long-run, necessarily fall upon the ground-rent. The final payment of this tax, therefore, would fall partly upon the inhabitant of the house, who, in order to pay his share, would be obliged to give up a part of his conveniency; and partly upon the owner of the ground, who, in order to pay his share, would be obliged to give up a part of his revenue. In what proportion this final payment would be divided between them, it is not, perhaps, very easy to ascertain. The division would probably be very different in different circumstances, and a tax of this kind might, according to those different circumstances, affect very unequally, both the inhabitant of the house and the owner of the ground.

The inequality with which a tax of this kind might fall upon the owners of different ground-rents, would arise altogether from the accidental inequality of this division. But the inequality with which it might fall upon the inhabitants of different houses, would arise, not only from this, but from another cause. The proportion of the expense of house-rent to the whole expense of living, is different in the different degrees of fortune. It is, perhaps, highest in the highest degree, and it diminishes gradually through the inferior degrees, so as in general to be lowest in the lowest degree. The necessaries of life occasion the great expense of the poor. They find it difficult to get food, and the greater part of their little revenue is spent in getting it. The luxuries and vanities of life occasion the principal expense of the rich; and a magnificent house embellishes and sets off to the best advantage all the other luxuries and vanities which they possess. A tax upon house-rents, therefore, would in general fall heaviest upon the rich; and in this sort of inequality there would not, perhaps, be any thing very unreasonable. It is not very unreasonable that the rich should contribute to the public expense, not only in proportion to their revenue, but something more than in that proportion.

The rent of houses, though it in some respects resembles the rent of land, is in one respect essentially different from it. The rent of land is paid for the use of a productive subject. The land which pays it produces it. The rent of houses is paid for the use of an unproductive subject. Neither the house, nor the ground which it stands upon, produce anything. The person who pays the rent, therefore, must draw it from some other source of revenue, distinct from and independent of this subject. A tax upon the rent of houses, so far as it falls upon the inhabitants, must be drawn from the same source as the rent itself, and must be paid from their revenue, whether derived from the wages of labour, the profits of stock, or the rent of land. So far as it falls upon the inhabitants, it is one of those taxes which fall, not upon one only, but indifferently upon all the three different sources of revenue; and is, in every respect, of the same nature as a tax upon any other sort of consumable commodities. In general, there is not perhaps, any one article of expense or consumption by which the liberality or narrowness of a man’s whole expense can be better judged of than by his house-rent. A proportional tax upon this particular article of expense might, perhaps, produce a more considerable revenue than any which has hitherto been drawn from it in any part of Europe. If the tax, indeed, was very high, the greater part of people would endeavour to evade it as much as they could, by contenting themselves with smaller houses, and by turning the greater part of their expense into some other channel.

The rent of houses might easily be ascertained with sufficient accuracy, by a policy of the same kind with that which would be necessary for ascertaining the ordinary rent of land. Houses not inhabited ought to pay no tax. A tax upon them would fall altogether upon the proprietor, who would thus be taxed for a subject which afforded him neither conveniency nor revenue. Houses inhabited by the proprietor ought to be rated, not according to the expense which they might have cost in building, but according to the rent which an equitable arbitration might judge them likely to bring if leased to a tenant. If rated according to the expense which they might have cost in building, a tax of three or four shillings in the pound, joined with other taxes, would ruin almost all the rich and great families of this, and, I believe, of every other civilized country. Whoever will examine with attention the different town and country houses of some of the richest and greatest families in this country, will find that, at the rate of only six and a-half, or seven per cent. upon the original expense of building, their house-rent is nearly equal to the whole neat rent of their estates. It is the accumulated expense of several successive generations, laid out upon objects of great beauty and magnificence, indeed, but, in proportion to what they cost, of very small exchangeable value. {Since the first publication of this book, a tax nearly upon the above-mentioned principles has been imposed.}
