Yes. Gain on the sale of your principal residence is tax free to the extent of your home sale exclusion. The basic exclusion of $250,000 ($500,000 on a joint return) applies only if you owned and used the home for two out of five years preceding the date of sale. However, if you haven’t yet satisfied these tests, you can prorate the exclusion for the period of time you did meet them where the sale is because of a job change. The fact that you continue to work for the same company is irrelevant.
A retirement account to which up to $4,000 (or $5,000 if you are 50 or over) may be contributed for 2007, but deductions for the contribution are restricted if you are covered by a company retirement plan. Earnings accumulate tax free.
