Monday Morning Outlook

The biggest tax debate in Washington right now is not between Republicans and Democrats, but between Republicans and Republicans. Both sides of the debate seem to understand that the US tax code, particularly the fact that the US has the highest corporate tax rate of any industrialized country, is harming the competitiveness of US companies.

Both sides want to cut this tax rate and both sides want to allow for full and immediate expensing of business investment in plant and equipment. Both sides also propose to end the deduction for the interest companies pay on their (new) debts.

What they're fighting about is making the US corporate tax system "border adjustable." Some want to exempt from taxation any income generated by exports, and at the same time, no longer allow US companies to deduct the cost of imports from revenue. Like a Value-Added Tax (VAT) used in many other countries, the idea would be to promote exports. Meanwhile, it would create a level playing field between foreign and US companies trying to sell to US consumers.

Let's say the new tax rate is 20%. A Napa Valley vineyard could produce a $100 wine and pay $20 in taxes. Then, after a retailer sells that bottle for $150, the retailer pays a $10 tax on their $50 profit. Total, the IRS gets $30. If the retailer buys the $100 bottle from a French vineyard and sells it for the same $150, the retailer now pays the 20% tax rate on the full $150, and so sends the IRS the total tax of $30.

The retailer's revenues don't change, but its tax payments to the IRS soar while its after-tax profits plummet. In effect, a border adjustable tax forces US retailers to attempt to extract tax payments from foreign producers or US consumers. This is why retailers in the US are fighting so hard against it.

Some say retailers shouldn't care because the value of the dollar will soar as well, reducing the cost of imports. But, if this is really true, why haven't all the other countries with border adjustments in their VATs been able to take down the dollar? The theory might work on an academic chalkboard, but the value of the dollar depends on many factors. Betting on a stronger dollar to fix border adjustable tax rate problems is a HUGE gamble.
