A Brief Overview of Depreciation. Depreciation is an income tax deduction that allows a taxpayer to recover the cost or other basis of certain property. It is an annual allowance for the wear and tear, deterioration, or obsolescence of the property.
How far back can you submit returns or amended returns and still get a refund? You can go back three years from the original deadline of the tax return to get a full refund. After three years, you will not be able to obtain a refund. It is important if changes are needed on an already filed return that these changes are made within the three year time frame.
There is no IRS deadline for overdue previous year tax returns, but in order to claim a tax refund for a certain year, you must file a tax return for that year within 3 years of the original due date. If you wait longer than 3 years, any tax refund is forfeit. On the other hand, past due taxes do not disappear.
