I have a client who has collected Service Tax. The said hs been paid in the next year. So for the current year, the said service tax is in the credit of Profit and Loss account and is also appearing in the Balance Sheet as a liability. So while computing the income tax return should I add back the amount of Service tax? Will it be disallowed?
