Can I use Form 3115 to create a "Depreciation Catch-Up" deduction that effectively neutralizes the "Depreciation Recapture" tax.

[ScottTseng]

Here is my situation:

Purchase a rental property for 625k at 2004
Plan to do a 1031 exchange at 2026, the estimated sale price: 2.5M
During the 22 years, no depreciation is ever taken.
Assumption: the depreciation is roughly 300k -> file Form 3115

Question: if I take out 300k cash (boot), can I offset the income with the 300k depreciation filing Form 3115?

No. You should file Form 3115 to catch up on depreciation. This reduces the basis of the exchanged property. If you don't, the depreciation you can take on the new property is technically limited to the allowable, which would be the same as if Form 3115 were filed.  Should you ever sell the property, you would still have to recapture any depreciation allowable but not claimed. Any gain is taxable to the extent boot is taken.

Thank you for the reply. I understand that the Boot is technically taxable income. However, since the Form 3115 generates a negative Section 481(a) adjustment in the same year, won't that passive deduction mathematically offset the passive income from the boot, resulting in zero net tax due?

[DaveF1006]

Not necessarily. If the property is a rental (passive activity), a negative §481(a) adjustment counts as a passive deduction. However, boot from a 1031 exchange is usually treated as capital gain, not passive income. 

Unless you qualify as a Real Estate Professional for tax purposes, a negative §481(a) adjustment may create a large passive activity loss that gets suspended and carried forward, instead of offsetting the capital gain from the boot.
