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.
The statute of limitations, or time allowed for the action, on getting a refund from an amended tax return is three years. That means if you're filing an amended tax return because you're hoping to get an additional refund, the cutoff time is three years after the original return was filed.
