The UK tax system’s contradictions — unfair to both unmarried couples and traditional families?
Financial planners are questioning whether the UK’s tax system has become inherently contradictory — disadvantaging both unmarried couples and traditional single-income families.
Under current rules, married couples and civil partners enjoy a range of tax advantages, including the ability to transfer assets between them without incurring Capital Gains Tax (CGT) and exemption from Inheritance Tax (IHT) on transfers to a spouse.
Unmarried couples, however, do not share these benefits — often facing larger IHT bills and limited flexibility in tax planning.
At the same time, the system tends to penalise traditional single-income families. Because personal allowances and tax bands are applied separately, for example, a household with one breadwinner can end up paying more tax than two individuals earning similar amounts between them.
This raises broader questions about fairness and consistency in the UK’s approach to taxation and family life.
We’re looking for expert comment:
- Do you agree that the UK tax system is inconsistent in how it treats different family types?
- Should unmarried couples receive the same tax treatment as married couples?
- Is the higher tax burden on single-income households fair, or does it discourage traditional family models?
- What reforms would you propose to create a fairer balance?
