I'm not so sure this is true. For any startup founders here, some questions:

1. How much time did you spend incorporating your business?

2. How much time do you spend per year filing your income taxes, or do you hire an accountant?

3. If the latter, how many billable hours do they put into it? Was this a major expense for your business?

There may be a huge step function if they somehow simplify the tax code such that small and medium business owners can do it themselves in a day rather than having to hire an accountant, but anything short of a major overhaul will leave people in roughly the same position I think.
