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.
On October 31, 2014, you filed an amended return and claimed a refund of $700. Although you filed your claim within 3 years from the date you filed your original return, the refund was limited to $200, the tax paid within the 3 years plus the 6-month extension period immediately before you filed the claim. The estimated tax of $500 paid before that period cannot be refunded or credited.
