The regular percentage depletion rate for independent producers and royalty owners remains at 15 percent for calendar year 2015. The regular percentage depletion rate for independent producers and royalty owners is 15 percent. For qualifying marginal production (less than 15 daily barrels of oil equivalent per day) the 15 percent rate is increased by one percentage point for each dollar the price of crude oil is less than $20 per barrel. With the barrel price exceeding $20 per barrel, there is no increase to the 15 percent rate. Percentage depletion for oil and gas production is 15 percent of gross revenue limited to 100 percent of a property’s net income. IRS Notice 2015-65, 2015-40 IRB 466.
