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.
In general, a taxpayer may file a claim for refund within three years from the time the refund was filed, or within two years from the time the tax was paid, whichever is later. If you filed your 2007 tax return by April 15, 2008 you have until April, 15 2011 to file an amended return for tax year 2007.
