Rounding error #2
Accrual taxation represents a major break from the current system as a move away from the realization principle, and it has several advantages. It would eliminate the lock-in effect, the use of capital-gains-bearing assets as tax shelters, and most of the incentive to shift labor income into capital gains. Because it restricts avoidance, accrual taxation would allow for a significantly higher tax rate on capital gains without inducing significant avoidance. Accrual taxation brings the tax system in line with the basic definition of income outlined above. It would increase the tax base and thus raise revenues. Using Survey of Consumer Finance data, Batchelder and Kamin calculate that accrual taxation (a) on marketable assets only and (b) limited to the top 1 percent of households would raise $1.7 trillion over ten years, even after allowing for a 15 percent avoidance rate.
