Making money from a pipeline easement is great. Keeping the money is more important and making sure you don't overpay taxes is a critical part of keeping your money.
Regretably, many easements are negotiated and fail to consider that if handled properly, the easement payments can be largely characterized as capital gains instead of ordinary income.
The IRS will consider a pipeline easement of 30 or more years in durtation as a "permanent" easement and generally afford it capital gain treatment. Almost always, landowners can secure long term treament as they have held the property for more than one year.
But the devil is in the details so be sure to attribute payment to the actual permanent easement. Otherwise, you might unwittingly be forced to claim income as "ordinary" and thus subject to higher tax rates than if you had attributed it so you could secure the lower capital gain rates.
