Many bookkeepers and business owners forget to book depreciation until the end of the year, sometimes never.
It is important that before using Tax Planner Pro, the financial statements include the correct depreciation before the financials are synced.
Work Around:
If you don't want to enter depreciation in the financials, at least make a depreciation account on the profit and loss and enter $1.00. Then the account will sync to Tax Planner Pro and you can override the amount to what you want.
Accounts that are $0 are not synced, that is why the account needs $1.00 booked to it.
