If client was in business for only 3 months, how do I enter the 3/12 months (business use period) for home office expense?

For a mid year start to the home office, take the amounts of the home expenses for the time using the office in business. For example, rent for 3 months = $3,000 and utilities for the 3 months totals $160. That gets to the correct amounts showing on the Form 8829 and being used in the allocation of home expenses.

How do you deal with the standard method ($5 per square foot)?
