In the US, two moderate incomes see a similar federal tax bill to a single person, with things actually getting worse at higher incomes for the married couple. Is the UK tax code really that different?
Huh? In the US the married filing jointly tax brackets are exactly double the single tax brackets for every rate except the top 37% rate. A single person making 100k definitely pays a lot more in tax than than a married couple making 100k together. It's generally advantageous to be married filing jointly unless you're at the absolute top 37% rate, at the very bottom (where means tested benefits phase out), or both spouses make roughly equal incomes (in which case MFJ vs two single filers works out around the same).
