I SOLD A BUSINESS PROPERTY AFTER THE BUSINESS FAILED HOW ARE TAXES DONE?

i tried to reopen a business that I had closed in jan of 2006 in jan of 2007, the business failed due to complications with the city. I sold the property and now I am confussed about taxation on the property. I bought it for 150,000 and sold it for 153000 minus real estate agent fees and closing costs, do I still owe taxes on this.
