The reason why closing stock is not taken into account in a
trial balance is because a trial balance is a balance of
all ledger account a given point in time.It records only
transactions which have a two way effect for EG:Purchases
where goods are bought against cash or credit and sales
where goods are sold against cash or credit..But closing
stock is not a transaction having a two way effect any
given point in time.It is only an indication of the goods
lying in the factory at the end of the year.It is therefore
showed below the trial balance and not in the trial
balance.However in order to derive at the exact gross
profit the closing stock is taken into consideration in the
trading account and also appears as an asset in the
balancesheet.
closing stock = opening stock + purchase – sales
This is because it is a post trial balance adjustment
effected after the trial balance has been adjusted. the
adjustment entry is as follows
DR Stock
CR Income Statement
The debit balance for stock is what appears in the balance
sheet.
The credit balance to the income statement is effectively a
deduction from cost of sales, since unsold stock is not part
of cost of sales for the period
Closing stock does not come in the trail balance beacuse the stock in hand
is already included in the purchases. If you want to include the closing stock
in the TB then you need to deduct the cost from the Purchases
