In “The True Worth of Your Muni Portfolio,” I thought of other ways of quantifying the investor-specific worth of a taxable portfolio. The market worth will not be appropriate, as a result of liquidating the portfolio would have tax penalties, and subsequently the liquidation worth could be totally different from the market worth. As an alternative of the market worth, I beneficial the “tax-smart” worth, which is the higher of the safety’s after-tax sale value and maintain worth.

Let’s calculate the tax-smart worth of a 10-year 5% bond bought two years in the past on the value of 113.3, whose present tax foundation is 111. Right now, with eight years remaining to maturity, the market value is 106. Sale at 106 would produce a 5-point long-term capital loss and subsequently a 1-point tax saving at a 20% tax price, leading to after-tax proceeds from sale of 107. This exceeds the 106 maintain worth, and subsequently right now the tax-smart worth is 107.
Must you promote this bond at 106 and understand the 5-point loss, or must you proceed holding it?
There are two funding methods: promote and reinvest, or do nothing. In case of a sale, the after-tax proceeds are reinvested in a like 5% 8-year bond, thus the par quantity of your holding would improve by an element 107/106.
Let’s calculate the tax-smart efficiency of the 2 methods one yr later, underneath two situations. What if charges decline and the worth will increase from 106 to 110? What if the worth drops to 102?

The tax-smart portfolio values equivalent to the 2 methods are proven within the accompanying tables. Observe that the tax foundation depends upon the technique: Underneath the do-nothing technique, primarily based on the unique 113.3 buy value, it’s 109.782. Underneath the promote and repurchase at 106 technique, it’s 105.352, and the notional quantity of the funding has elevated by an element 107/106. The tax-smart returns, as measured by IRR, rely upon the terminal tax-smart portfolio values and the coupon curiosity obtained in the course of the yr.
Situation 1: Value Rises to 110 in 12 months 3
12 months 2 Tax-Sensible Worth ($M) | Technique In 12 months 2 | 12 months 3 Market Worth ($M) | 12 months 3 Foundation ($M) | 12 months 3 Tax-Sensible Worth ($M) | Adjusted Semiannual Coupon ($M) | 12 months 3 Return (%) |
107.0 | Promote/Reinvest | 111.038 | 106.346 | 111.038 | 2.524 | 8.414 |
107.0 | Do Nothing | 110.000 | 109.782 | 110.000 | 2.500 | 7.426 |
If the worth will increase to 110, the return primarily based on sale in 12 months 2 is 8.414%, and with out sale it’s 7.426%. The roughly 1% distinction is because of the alternative price of not recognizing the capital loss on the finish of 12 months 2 — as soon as the worth will increase, such alternative could also be misplaced without end.
Situation 2: Value Falls to 102 in 12 months 3
12 months 2 Tax-Sensible Worth ($M) | Technique in 12 months 2 | 12 months 3 Market Worth ($M) | 12 months 3 Foundation ($M) | 12 months 3 Tax-Sensible Worth ($M) | Adjusted Semiannual Coupon ($M) | 12 months 3 Return (%) |
107.0 | Promote/Reinvest | 102.962 | 106.346 | 103.639 | 2.524 | 1.589 |
107.0 | Do Nothing | 102.000 | 109.782 | 103.556 | 2.500 | 1.466 |
If the worth declines to 102, the efficiency of the tax-loss promoting technique remains to be barely higher: 1.589% vs. 1.466%. The distinction is partly attributable to the higher curiosity revenue from reinvestment underneath the tax-loss promoting technique, and it additionally depends upon the amortization of the premise equivalent to totally different buy costs.
Realizing a loss and reinvesting has a further profit: It restarts the short-term clock. Lengthy-term losses are deductible at 20%. Brief-term losses, or these incurred in lower than one yr, will be deducted on the a lot greater price of 40%, supplied that there are offsetting short-term features. Assuming such is the case, if the market value declines to 102, the three.384 loss (106.346-102.962) would end in 1.354 tax financial savings. The tax-smart terminal worth would improve to 104.316, and the return to 2.223%, from 1.589%.

In abstract, tax-smart portfolio valuation alerts alternatives to enhance after-tax efficiency by recognizing losses. It pinpoints promoting alternatives by evaluating after-tax proceeds from sale to carry worth. Sale and reinvestment is especially efficient if the worth subsequently improves, because of the alternative price related to staying idle. If the worth subsequently declines, restarting the short-term clock supplies a possibility to acknowledge short-term losses at a excessive efficient tax price, additional enhancing efficiency relative to doing nothing.
