DTA and DTL

Deferred tax assets in balance sheet of a company are those assets or say items which uses to reduce the taxable income in the future
it arises when there's is difference in tax rules and accounting rules or there's is carry over of taxlosses

where's as deffered tax liability is opposite to it
it is those items which can increase the amount of income tax owed by a company
it's an obligation to pay tax in future by company

Ok. whether it is ok if entity credits the DTA to P&L account.?

If you will create different tax asset it will be treated as income and when you will create the fat tax liabilities it will be treated as expense.

it will be adjusted with current year tax as a tax expense or income
