yes. There is no limit on the number of years you can claim capital losses. But there is a limit on the amount that is 'allowed" each year. You still claim the full amount. The program will "know" what the allowed amount is, if you exceed it, and takes care of it accordingly.
Is this a SCH C business? I ask, because when you close it down in 2017, you MUST file a SCH C for your 2017 taxes and make SURE you report not only that you closed, sold or otherwise disposed of the business in 2017, you also have to show the disposition of any and all business assets associated with the business too. That's important, but you can deal with that on your 2017 taxes when the time comes. We'll still be here if you need help then.
