What Is Annualized Income?

Annualized income is an estimate of the sum of money that an individual or a business generates over a year’s time. Annualized income is calculated with less than one year’s worth of data, so it is only an approximation of total income for the year. Annualized income figures can be helpful for creating budgets and making estimated income tax payments.

Understanding Annualized Income

Annualized income can be calculated by multiplying the earned income figure by the ratio of the number of months in a year divided by the number of months for which income data is available. If, for example, a consultant earned $10,000 in January, $12,000 in February, $9,000 in March and $13,000 in April, the earned income figure for those four months totals $44,000. To annualize the consultant’s income, multiply $44,000 by 12/4 to equal $132,000.

How Estimated Tax Payments Work

Taxpayers pay annual tax liabilities through tax withholdings and by making estimated tax payments each quarter. There are many sources of income that are not subject to tax withholding. Income from self-employment, interest and dividend income and capital gains are not subject to tax withholdings, along with alimony and some other sources of income that may be reported to a taxpayer on Form 1099. To avoid a penalty for tax underpayment, the total tax withholdings and estimated tax payments must equal to the lesser of 90% of the tax owed for the current year or the full tax owed the previous year.

Examples of Annualized Income That Fluctuates

Computing estimated tax payments is difficult if the taxpayer’s income sources fluctuate during the year. Many self-employed people generate income that varies greatly from one month to the next. Assume, for example, that a self-employed salesperson earns $25,000 during the first quarter and $50,000 in the second quarter of the year. The higher income in the second quarter indicates a higher total level of income for the year, and the first quarter’s estimated tax payment is based on a lower level of income. As a result, the salesperson may be assessed an underpayment penalty for the first quarter.

Factoring in the Annualized Income Installment Method

To avoid the underpayment penalties due to fluctuating income, the IRS Form 2210 allows the taxpayer to annualize income for a particular quarter and compute the estimated tax payments based on that amount. Schedule AI of Form 2210 provides a column for each quarterly period, and the taxpayer annualizes the income for that period and computes an estimated tax payment based on that estimate. Using the salesperson example, Form 2210 allows the taxpayer to annualize the $25,000 first quarter income separately from the $50,000 second quarter income.

What Is the After-Tax Real Rate of Return?

The after-tax real rate of return is the actual financial benefit of an investment after accounting for the effects of inflation and taxes. It is a more accurate measure of an investor’s net earnings after income taxes have been paid and the rate of inflation has been adjusted for. Both of these factors must be accounted for because they impact the gains an investor receives. This can be contrasted with the gross rate of return and the nominal rate of return of an investment.

Understanding the After-Tax Real Rate of Return

Over the course of a year, an investor might earn a nominal rate of return of 12% on his stock investment, but the real rate of return, the money he gets to put in his pocket at the end of the day, will be less than 12%. Inflation might have been 3% for the year, knocking his real rate of return down to 9%. And since he sold his stock at a profit, he will have to pay taxes on those profits, taking another, say 2%, off his return, for an after-tax real rate of return of 7%.

The commission he paid to buy and sell the stock also diminishes his return. Thus, in order to truly grow their nest eggs over time, investors must focus on the after-tax real rate of return, not the nominal return.

The after-tax real rate of return is a more accurate measure of investment earnings and usually differs significantly from an investment’s nominal (gross) rate of return, or its return before fees, inflation, and taxes. However, investments in tax-advantaged securities, such as municipal bonds and inflation-protected securities, such as Treasury inflation protected securities (TIPS), as well as investments held in tax-advantaged accounts, such as Roth IRAs, will show less discrepancy between nominal returns and after-tax real rates of return.

Example of the After-Tax Real Rate of Return

Let’s be more specific about how the after-tax real rate of return is determined. The return is calculated first of all by determining the after-tax return before inflation, which is calculated as Nominal Return x (1 – tax rate). For example, consider an investor whose nominal return on his equity investment is 17% and his applicable tax rate is 15%. His after-tax return is, therefore:
$0.17 \times (1 – 0.15) = 0.1445 = 14.45\%$0.17×(1−0.15)=0.1445=14.45%

Let’s assume that the inflation rate during this period is 2.5%. To calculate the real rate of return after tax, divide 1 plus the after-tax return by 1 plus the inflation rate, then subtract 1. Dividing by inflation reflects the fact that a dollar in hand today is worth more than a dollar in hand tomorrow. In other words, future dollars have less purchasing power than today’s dollars.

Following our example, the after-tax real rate of return is:

$\frac{(1 + 0.1445)}{(1 + 0.025)} – 1 = 1.1166 – 1 = 0.1166 = 11.66\%$(1+0.025)(1+0.1445)​−1=1.1166−1=0.1166=11.66%

That figure is quite a bit lower than the 17% gross return received on the investment. As long as the real rate of return after taxes is positive, however, an investor will be ahead of inflation. If it’s negative, the return will not be sufficient to sustain an investor’s standard of living in the future.

The Bottom Line

When you are assessing the value of your investments, it’s important to look at not just your nominal rate of return but also the after-tax real rate of return, which takes into account the taxes you’ll owe and inflation’s effect. The after-tax real rate of return can tell you if your nest egg investments will allow you to maintain your standard of living in the future.

What Is an A-B Trust?

An A-B trust is a joint trust created by a married couple for the purpose of minimizing estate taxes. It is formed with each spouse placing assets in the trust and naming as the final beneficiary any suitable person except the other spouse. The trust gets its name from the fact that it splits into two separate entities when one spouse dies. Trust A is the survivor’s trust and trust B is the decedent’s trust.

Understanding an A-B Trust

Estate taxes can bite deeply into a deceased person’s assets. For example, consider a married couple that has an estate worth $20 million by the time one of the spouses dies. The surviving spouse is left with the whole $20 million, which is not taxed due to the unlimited marital deduction for assets flowing from a deceased spouse to a surviving spouse.

But then, the other spouse dies, leaving the money to their children. The taxable portion of the estate (the amount that exceeds the 2022 exemption threshold of $12.06 million will be $7.94 million). This means that $7.94 million will be taxed at 40%, leaving only $4.76 million for the beneficiaries. The exemption for 2023 is $12.92 million.

To circumvent the estate from being subject to such steep taxes, many married couples set up a trust under their last will and testaments called an A-B trust. In the example above, if the couple instead had an A-B trust, the death of the first spouse would not trigger any estate taxes as a result of the lifetime exclusion; however, a sum of money equal to the current exemption amount will be transferred into an irrevocable trust called the bypass trust or B trust.

This trust is also known as the decedent’s trust. The remaining amount, $7.94 million, will be transferred to a survivor’s trust, or A trust, which the surviving spouse will have complete control over. The estate tax on the A trust is deferred until after the death of the surviving spouse.

Benefits of an A-B Trust

The A trust contains the surviving spouse’s property interests, but they have limited control over the assets in the deceased spouse’s trust; however, this limited control over the B trust will still enable the surviving spouse to live in the couple’s house and draw income from the trust, provided these terms are stipulated in the trust.

While the surviving spouse can access the bypass trust, if necessary, the assets in this trust will bypass their taxable estate after they die. After the surviving spouse dies, only the assets in the A trust are subject to estate taxes. If the estate tax exemption for this spouse is also $12.06 million for 2022 (the exemption threshold for 2023 is $12.92 million) and the value of assets in the survivor’s trust is still valued at $7.94 million, none of it will be subject to estate tax.

The federal tax exemption is transferable between married couples through a designation referred to as the portability of the estate tax exemption. If one spouse dies, the unused portion of their estate tax exemption can be transferred and added to the estate tax exemption of the surviving spouse. Upon the death of the surviving spouse, the property in the decedent’s trust passes tax-free to the beneficiaries named in this trust.

This is because the B trust uses up the estate tax exemption of the spouse that died first, hence, any funds left in the decedent’s trust will be passed tax-free. As the decedent’s trust is not considered part of the surviving spouse’s estate for purposes of the estate tax, double taxation is avoided.

Net Worth and A-B Trusts

If the deceased spouse’s estate falls under the amount of their tax exemption, then it may not be necessary to establish a survivor’s trust. The unused portion of the late spouse’s federal tax exemption can be transferred to the surviving spouse’s tax exemption by filling out IRS Form 706.

While A-B trusts are a great way to minimize estate taxes, they are not used much today. They were popular in the decades around the turn of the 21st century when the estate tax—which hadn’t been adjusted for years—could be triggered on estates as small as $1 million or $2 million. Nowadays, each individual has a combined lifetime federal gift tax and estate tax exemption of $12.06 million in 2022, rising to $12.92 million in 2023.

So only people with estates valued over $12.06 million will opt for an A-B trust in 2022. With the portability provision, a surviving spouse can include the tax exemption of their late spouse, allowing up to $24.12 million as of 2022 and $25.84 million in 2023, which can be transferred tax-free to beneficiaries.
