If you want to split the 1099-S 50/50 between the two of you is fine. When a married couple sell their primary residence that they have lived in for at least two of the last five years, the IRS allows a capital gain exclusion for that sale. For a married couple filing separately, the exclusion is up to $250,000 for each spouse, and up to $500,000 for a married couple filing jointly. For more information on the capital gain exclusion see this Link:
