How do you decide when to capitalize rather than expense a purchase?

If the asset has a useful life of over 1 year, it is capitalized (put on the Balance Sheet rather than shown as an expense on the Income Statement). Then it is depreciated (tangible assets) or amortized (intangible assets) over a certain number of years.

Purchases like factories, equipment, and land all last longer than a year and therefore show up on the Balance Sheet. Employee salaries and the cost of manufacturing products (COGS) only cover a short period of operations and therefore show up on the Income Statement as normal expenses instead.
