We can all admit that we don’t know everything and more often than not, we don’t have the time (or the will power) to trawl through the internet trying to find the information we need. So to help you out we’ve compiled a few handy website links about oil and gas taxation.

Petroleum Tax

Overview Of PRT – Computation Of PRT Charge

As PRT is a field related tax the charge to PRT is primarily based on a participator’s share of the taxable income from the field less the participator’s share of the allowable costs for that field. There are however special rules that also allow certain types of non-field related costs and in addition to costs there are also some further allowances and reliefs that are available on a field specific basis.
