There is still some ambiguity. However, I shall try and clear them.
Firstly, the cash. The Cash account shall be closed as :
Retained Earnings A/c DR $ 1000
TO Cash A/c $ 1000
Then comes the equipment. The equipment needs to be sold and once you get the cash, it should be similarly be transferred to the Retained earnings account.
Then comes the depreciation. This is accumulated depreciation. i.e. something accounted for but not spent. This also needs to be closed and transferred to Retained Earnings.
Retained Earnings A/c DR
To Depreciation A/c
This will Close the Depreciation A/c
Now, if there is a single shareholder, this will represent the capital and the retained earnings would be equal to the capital as of end of that aaccouting period.
This canbe closed by making a payout to the single shareholder as :
Bank / Cash A/c DR
To Shareholder Account.
This will close all account and wind up the corporation.
I hope the above helps...
