In addition to the common treasury, supported by the general taxes and charged with the ordinary expenditure, there was a special reserve fund, also in the temple of Saturn, the ''aerarium sanctum'' (or ''sanctius''). This fund probably originally consisted of the spoils of war
. Afterwards it was maintained chiefly by a 5% tax on the value of all

Under the emperors, the Senate continued to have at least the nominal management of the aerarium, while the emperor had a separate exchequer, called
Fiscus, from which comes the English term ''fiscal,'' was the name of the personal chest of the emperors of Rome.
The word is literally translated as "basket" or "purse" and was used to describe those forms of revenue collected from the provinces
. However, after a time, as the power of the emperors increased and their jurisdiction extended until the Senate existed only in form and name, this distinction virtually ceased.
Besides creating the ''fiscus'', Augustus also established in AD 6 a military treasury ''(aerarium militare)'' as a fund for veterans' retirement benefits. It was largely endowed by the emperor himself and supported by the proceeds of new taxes, an

and a sales tax on auctions. Its administration was in the hands of three ''praefecti aerarii militaris''. At first these were appointed by lot, but afterwards by the emperor, from senators of praetorian rank, for three years.
The ''tribuni aerarii'' ("tribunes of the treasury") have been the subject of much discussion. They are supposed by some to be identical with the ''curatores tribuum'', and to have been the officials who, under the Servian organization

''. They also acted as paymasters of the equites and of the soldiers on service in each tribe. By the lex Aurelia
(70 BC) the list of judices was composed, in addition to senators and equites, of tribuni aerarii. Whether these were the successors of the above, or a new order closely connected with the equites, or even the same as the latter, is uncertain.

, but replaced by Augustus. According to Madvig
, the original tribuni aerarii were not officials at all, but private individuals of considerable means, quite distinct from the curatores tribuum, who undertook certain financial work connected with their own tribes. Then, as in the case of the equites, the term was subsequently extended to include all those who possessed the property qualification that would have entitled them to serve as tribuni aerarii.
