Half a million working families are set to lose more than £1,000 a year in tax credit allowances, according to a recent report from the Trade Union Congress (TUC).
The emergency Budget announced on 22 June outlined tariff changes, which will now discount any loss of income up to £2,500, meaning levies will not be adjusted downwards according to reduced revenue.
TUC general secretary Brendan Barber said that the new regulations were "buried in small print", meaning that many families who lose out may be unaware of the effect the regulation amendment will have on their financial planning.
Commenting on a recent survey about women and work, the organisation noted that there is still much to be done to achieve equality in employment, as a gender pay gap persists in many sectors of the economy.
New rules surrounding tax credits may therefore be seen as another sign of unfair legislation on private life and commercial interests.
Tax credit changes cost families £1,000
The FSA does not regulate tax advice. Tax rules are subject to change.
