Accountants and tax professionals say the summer is a good time to take stock of a company and see whether it’s meeting its goals and whether there’s enough cash on hand for tax payments. It’s also time to make decisions about equipment purchases and other capital spending for the second half of the year.

“You want to assess: Are you making money or are you losing money?” said Barbara Weltman, a tax attorney in Millwood, N.Y., and author of “J.K. Lasser’s Small Business Taxes.”

That may sound overly simplistic, but tax professionals say many owners really don’t know where their companies stand, and those who are losing money need to find that out fast and start making changes. Companies that are doing well should start thinking about their options — for example, should the owner or owners withdraw money or leave it with the business to pay for its future growth.
