Taxes on land, income and the sale of goods are generally set by each individual province and decided at the Regional Assemblies. Allocation of funds collected, and problems with the administration of their collection, are also resolved at this level. However, central government issues the parameters within which these can be decided; the maximum and minimum amount of tax and which areas they should go into (e.g. the Guards, poor relief etc.) The parameters are drawn up jointly between the Mayering Rooms and Huwdone House and voted on by Parliament each February. They have varied considerably over the years but successive Chancellors have generally kept with the high-tax, high-spend policies, especially hitting high incomes and land ownership. Though making perennial attempts to reduce levels, the wealthy are more or less resigned to paying more, providing the economy remains strong enough to compensate.
In addition to usual taxes, a centrally-imposed charge is levied on each of the seven provinces, assessed according to need and ability to pay. Supposed to fund foreign policy expenses, the administration of the federal government, housing foreign ambassadors, trans-federal projects (e.g. the building of the South Passage Road) and the like, it's an obviously unpopular burden on the provinces. Its introduction in the 1100's was one factor leading to the civil wars, and though it survived them it has been kept as low as possible.
