Here is a good answer I found online because I was wondering the same thing:
“With most of your ordinary business expenses, if you have more expenses than you have income, your business can show a net operating loss that may be deductible against any other regular income you have (such as interest, dividends, or income from another job or business). This may even be true if the loss is a “paper loss” resulting from depreciation. However, it is not true of the home office deduction.
Your home office deduction is limited by the amount of your net business income. If your net income is too low, you won't be able to deduct the entire amount of your home office deduction this year (although you may carry it over and deduct it in a later year when your net business income is higher). “
Looks like only the home office deduction has to stop at 0 and then you carryforward the rest. Otherwise you just end with a NOL for the year.
