How should I determine my share of costs for qualified property when the costs were paid by the co-op or condominium board or management association?

You'll need to determine your share of costs for your living situation. For co-ops you may own a certain number of stocks as a tenant-stockholder out of a total number of stocks available. Your stocks divided by the total stocks would be your share percentage. For condominium complexes, you may be designated an interest share based on the square footage of your home divided by the total square footage of all homes in the complex. In this case, your square footage divided by the total square footage of all homes in the complex would be your share percentage.

Your share percentage multiplied by the total cost paid by the co-op or condominium board or management association would then be the amount of cost allocated to you that you would enter in the software.

You can contact your co-op or condominium board or management association for help determining your share of costs.
