Higher earners could benefit most from the tax bill in the short run, but future generations of all incomes would be 'worse off,' per a new analysis.

What the bill does do is provide a temporary tax deduction of up to $6,000 for seniors aged 65 and older. The tax break is available to people with an adjusted gross incomes of $75,000 or less and $150,000 or less for couples filing jointly. The deduction is set to expire at the end of 2028.
