Depreciation is recaptured if you sell an asset for more than its depreciated basis. People sometimes get into trouble with this if they rapidly depreciate real estate and then sell it. Even if you sell for less than your purchase price it is possible to owe taxes.
You also aren't going to be able to pay no taxes since you do need to realize some income to pay for mortgage/rent, food, transportation, etc. I guess if you had assets you could borrow against it would be possible to pay for these using the loan proceeds (which are not taxable).
