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.
If you file your claim within 3 years after filing your return, the credit or refund cannot be more than the part of the tax paid within the 3 years (plus the length of any extension of time granted for filing your return) before you filed the claim.
