How do I properly claim Work-Space-in-the-Home percentage if I moved halfway through the year and the homes and office are different sizes, hence different claimable %

You will need to find the "average" percentage for both locations and enter that number in.

For example:

• Home A - 300 sq ft/1000 sq ft home = 30%
• Home B - 360 sq ft/2000 sq ft home = 18%
• Average space used is 24%. Enter in TurboTax as 24 of 100 ratio. 

You can total your expenses from both locations and enter as such.
