According to the Oklahoma instructions, "Upon the expiration of the lease, depletion claimed must be restored to income in the case of non-producing properties. Enter depletion claimed on a lease bonus if no income was received from the property due to its lease expiration. A complete schedule by property must be furnished.
If the 22% Oklahoma option for computing depletion was used in a previous year and the 65% Federal depletion limitation applied in that year, you must add back any unused Federal depletion being carried over from such year and used in the current year’s Federal return. Applicable recapture is determined on a well-by-well basis."
Note: Major oil companies when computing depletion should be limited to 50% of the net income as defined in 52 OS Sec. 288.2.
