I am planning to sell the software to the C-Corp.  The software is custom made, not off-the-shelf one, so it will be entirely depreciated within 3 years.  Under the IP assignment agreement, the C-Corp must pay for the software in 1 payment within 5 years - after full depreciation.  The C-Corp uses cash accounting method.  So, do I get it right that the C-Corp: (1) may depreciate the software before it pays for it; and (2) will not pay any tax, which will relate to this transaction?
