I have side businesses in addition to W2 income but zero side income this year. Can I file a self employed return and claim the expenses?

Yes, you can still input your expenses even if you only had a no income or a small amount of income.

In Self-Employed online, follow these steps to get to where you need to start entering the details to create the Schedule C, so that you can enter your business expenses. 

• Log into your account and click orange Take me to my return button
• Type schedule c in the Search box in top right corner
• Click on jump to schedule c and this should bring you to the Did you have any income and expenses for a business in 2016? screen and you choose Yes there. 
• It will ask you some information about your business and once you get the the Your Business page, scroll down to Business Expenses and start entering your expenses there.
