asked the Chancellor of the Exchequer what steps he proposes to take to remove the sex discriminatory anomalies that exist in matters concerning the collection and, where appropriate, refund of income tax.

The procedures for collecting and refunding income tax do not in general distinguish between people on the grounds of sex. They make some distinction between married and single women, but those differences flow mainly from the rule that the income of a married woman is aggregated with her husband's for tax purposes.
