I am depreciating a vacation home used as a rental with partial use in 2017 (year placed in service), and for 2018. How does TT calculate the depreciation for 2018?

[johnpango]

Years: 27.5

MACRS Convention: MM

Method: SL

Depreciation Starting Value (minus land): $310624

Date Placed in Service: 10/27/17

Business Use: 55.63%

Prior Depreciation: $2068

2017 Business Use was: 87.88%

2017 Depreciation (assuming 100% use): $2353

2017 Depreciation (with 87.88 use): $2068 - what TT reported last year

The depreciation deduction it calculated this year was $6256

I cannot arrive at this number manually and cannot determine how TT is determining this number.

TurboTax does not use the 'tables' for depreciation.

$310,624 x 55.56% = $172,583 = Unadjusted Business Basis for 2018

$172,583 - $2068 = $170,732 = Adjusted Business Basis for 2018

$170,732 divided by 27.29 years (the remaining portion of the 27.5 years) = $6256
