Any general tendency either to stability, or increase or decrease which might also have influenced the figures of the past years and the new sums of revenue of which no account has been taken in the previous year. should also be kept in view for arriving at an accurate estimate of the Receipt. No income from any tax shall be shown on the Receipt side unless the imposition of tax is actually approved by the competent authority.
