Am I required to report a loss on a business which I no longer operate?

I am married and file a joint return. My husband and I took a one-time shot at a new business in 2010 and we came out with a net loss. However, we already have plenty of other tax deductions and will not benefit additionally from reporting any deductions ociated with this business endeavor. It was a retail sales venture and we have already paid the required sales tax to the state board of equalization. So...can we file our return without including this little business venture?
