Important: This is an educational preliminary estimate, not a tax-return calculation. The actual-expense method can involve direct versus indirect expenses, depreciation for homeowners, income limitations, carryovers and other rules. Mortgage interest and real estate taxes may also have separate personal deduction treatment. Eligibility generally requires qualified business use of the home. Special rules apply to daycare, inventory storage, part-year use and other situations.
