Although the 2013 tax booklet is not yet available, it appears the depletion factors for 2013 have been entered into the online depletion calculator at the PBT website. However when I enter a lot that I sold in March 2013, it comes back with negative depletion for the Waddel Ranch oil properties and positive depletion for the others. That doesn't make much sense to me. Anyone have an opinion on negative depletion?
Also depletion is about about 1/3 less than last year. At one time PBT produced a net loss as depletion exceeded income but that is no longer the case. The depletion calculator is a good tool and makes it easy to calculate depletion (assuming it is working ok)
