Tax Reform

Question A:

Eliminating tax deductions for non-investment personal interest expenses (e.g., on mortgages), with reductions in personal tax rates that are both budget neutral and keep the burden of taxes by income group the same, would lead to more efficient financing decisions by individuals.

Responses weighted by each expert's confidence

Question B:

Reducing the deductibility of interest expenses for non-financial businesses to equalize the overall tax cost of debt and equity financing, while using the extra revenue to reduce personal and corporate tax rates in a budget neutral fashion that also keeps the burden of taxes the same, would lead to more efficient financing decisions by firms.

There is no reasonable Pigovian justification for mortgage deductions, which are not only distortionary but also generally regressive.

The interest deduction distorts consumption decisions in favor of housing and narrows the income tax base, requiring higher tax rates.

Trick question. i object. financing could be less efficient-- it would bias to pay cash instead of borrowing. housing choice would be better

In theory, of course, but unclear how to measure it in practice. Note: tax subsidies for debt may serve other social purposes.

Ideal solution is to tax imputed rent. As this is difficult in practice, it's better to not allow interest deductions
