There is no inheritance tax, at least in BC. An estate does have to pay off any debts owed and that may include income taxes, unpaid bills, etc. Further, if an estate has to go through probate there are fees payable to the courts that are a percentage of the value of the estate. People often think those are estate taxes when in fact they are probate fees (having said that it all goes to the government and so effectively they are the same).
The probate fee is not payable if an estate is worth less than $25,000.00.
If the esatte is worth more than $25,000 the fee is
(3) If the value of the estate exceeds $25 000, whether disclosed to the court before or after the issue of the grant or before or after the resealing, as the case may be, the amount of fee payable is
(a) $6 for every $1 000 or part of $1 000 by which the value of the estate exceeds $25 000 but is not more than $50 000, plus
(b) $14 for every $1 000 or part of $1 000 by which the value of the estate exceeds $50 000.
The above is taken from the Probate Fee Act of BC.
