Statements required by the SEC are not the same as those sent to the IRS.

For example, a company can use straight-line depreciation in their GAAP statements, but use accelerated depreciation for tax purposes. The difference becomes a tax credit on the balance sheet.

The IRS is much less likely to fall for shenanigans than investors.

If that's the goal, they're doing it badly since the non-GAAP measures show higher profits.

You can't (quite) choose how you report your profits to the IRS. This is about reporting the company's books to investors.
