Since we are just trying to see the effect of taxes, lets assume that both the principal invested and the return (we can assume a bond coupon payment) are inflation protected. (i.e. the only thing not indexed to inflation are the tax rates)
2 scenarios. 100 investment. coupon =10%, taxes 20%,
1. no inflation.
100*1.1=110/100-1=10% pre tax real return
100+(10*.8)=108/100-1=8% after tax
2. 20 % inflation
100*1.2=120
10*1.2=12
132/1.2=110/100-1=10% pre tax real return
100+(32*.8)=125.6/1.2-1=4.67% after tax
In scenario 2, we are taxed on the inflation impact of the investment (even though there was no real “gain” to us in terms of purchasing power)
I would never go as far as to assume changing marginal tax rates or anything like that. I can see how that makes sense, but reaching…
Just a guess |
