The budget included several proposed tax increases to fund the Liberal welfare reforms. Income tax was held at nine pence in the pound (9d, or 3.75%) on incomes less than £2,000, which was equivalent to roughly £225,000 in today's money—but a higher rate of one shilling (12d, or 5%) was proposed on incomes greater than £2,000, and an additional surcharge or supertax of 6d (a further 2.5%) was proposed on the amount by which incomes of £5,000, or more (approximately £566,000 today) exceeded £3,000 (£340,000 today approx.). An increase was also proposed in death duties and naval rearmament.
