Learn what taxable yield means, how taxes reduce an investor’s after-tax income, and why nominal yield alone can be misleading.
The taxable yield is the yield on an investment whose interest or income is subject to tax.
Investors care about taxable yield because the headline yield is not always the amount they keep after taxes.
If an investment pays interest that is fully taxable, the investor’s after-tax result depends on both:
A simplified relationship is:
after-tax yield = taxable yield x (1 - tax rate)
Suppose a bond offers a taxable yield of 5% and the investor faces a 30% marginal tax rate.
The after-tax yield is:
5% x (1 - 0.30) = 3.5%
That means the investor keeps an after-tax yield of 3.5%, not the full 5%.
An investor says, “The higher coupon bond is automatically better.”
Answer: Not necessarily. A higher taxable yield can still produce a worse after-tax result than a lower tax-advantaged yield.
