AA: Why 30% tax adjustment for taxable account?

[marek]

Where is 30%-20% reduction of the value of the taxable account coming from for the Tax Adjusted Asset Allocation? Should it be just reduced by the taxes on capital gain?

You should also reduce the value of your taxable account by about 30% if you are early in your career, and 20% if you are near or in retirement,

Maybe the person who added that lives in California or NY and were including both state and federal income taxes?

I think one can come up with a number as low as 0% if they think about it carefully.

Because you will pay tax on dividends every year, compounding for as long as you hold the funds, and then 15% tax on your capital gains when you sell. If you hold a fund which pays 2% per year in qualified dividends, for 30 years, you will lose 0.3% per year, for a total of 9%, and you will then lose another 15% of your gains, probably 12% of your fund value, when you sell. This is a 20% loss.

I changed the numbers to 25% and 15%; the old 30% and 20% numbers were correct under the assumption that the tax break on qualified dividends would be allowed to expire.
