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.
Whichever of the following dates occurs last is your deadline to file a timely claim for refund: 1  Three years from the due date of the return on which you paid too much tax. 2  Six months from the date you overpaid tax. 3  Six months from the date a determination (billing) became final.
