How do you prepare for Tax Season?

[Shane Welch]

Hello, I just purchased my first duplex last month.  What is your practices for preparing for tax season?

Should I scan all receipts, keep in a folder on my desktop? or keep a binder of all receipts?
Is excel good a good thing to use to keep track on Income/Expenses, helpful to a tax advisor or accountant?

What have you found to be a simple/stress free way of keeping your business organized financially? 

Thank you for your time.
