Thank you. 

I am a bit confused and would greatly appreciate clarification. A bit embarrassed to be asking this so please bear with me.

For an S-Corporation that uses SL depreciation for book purposes and MACRS for tax purposes, is the following correct?

• Schedule L will be per books using book depreciation instead of tax depreciation
• Schedule M-1 will show the book-to-tax difference for depreciation on line 6a (for years when MACRS > SL)
• Schedule M-2 won't match RE on Schedule L and the difference will be any non-deductible expenses, such as 50% of meals.
• Shareholder Basis Calculation will match Schedule M-2

I know there's a lot going on in my question but I am just a bit confused about the interplay because it seems too many things aren't matching when there are two different depreciation methods (book and tax)
