We provide a full report that includes the following:   Summary of tax benefits and additional deductions generated from Cost Segregation.Detailed schedule of the property's major costs organized by tax category (used to complete your tax return).Excel export in depreciation schedule format (that can be directly imported into many tax software programs)Summary of all information used to produce the report For an additional fee – 481(a) adjustment “missed deduction” calculation schedules (needed for properties acquired in prior tax years).For investors with properties, such as commercial or extensive multi-family properties, etc., I can recommend a firm with a Nationwide presence to work on these types of engagements.
