BREAKING DOWN 'Percentage Depletion'
Oil and gas investments at the wellhead have become one of the most tax-advantaged investments available in America today, because of the depletion allowance. Approximately 15% of all income from oil and gas is tax-free for small investors and producers. There is no dollar limit as to the total amount of depletion one can deduct from income from qualified nonrenewable resources.
