That's an pointless way of expressing the percentage of taxation, and will inevitably lead to > 100% taxation, but that's not a useful way of looking at it. Imagine an income tax model where everything less than $200k was untaxed, and everything above $200k is taxed at 20%, and tax is always rounded down towards the next cent value. Thus $200.04 pays 0 tax, and $200.05 pays 1 cent tax. That 1 cent is '100% taxed', but given that would exist no matter what values you choose, it's not a helpful way of describing the taxation.
