Taxation of social security benefits
How are Social Security benefits taxed? That depends on your
other income. In the worst case scenario, 85% of your benefits would be taxed.
(This doesn't mean you pay 85% of your benefits back to the government in
taxes-merely that you would include 85% of them in your income subject to your regular
tax rates.)
To determine how much of your benefits are taxed, you must first
determine your other income, including certain items otherwise excluded for tax
purposes (for example, tax-exempt interest). Add to that the income of your
spouse, if you file jointly. To this add half of the Social Security benefits
you and your spouse received during the year. The figure you come up with is
your total income plus half of your benefits. Now apply the following rules:
1. If your income plus half your benefits is not above $32,000 ($25,000
for single taxpayers), none of your benefits are taxed.
2. If your income plus half your benefits exceeds $32,000 but is
not more than $44,000 (exceeds $25,000 but is not more than $34,000 for single
taxpayers), you will be taxed on (1) one half of the excess over $32,000
($25,000 for single taxpayers), or (2) one half of the benefits, whichever is
lower.
Example (1): S
and D have $20,000 in taxable dividends, $2,400 of tax-exempt interest, and
combined Social Security benefits of $21,000. So, their income plus half their
benefits is $32,900 ($20,000 plus $2,400 plus 1/2 of $21,000). They must
include $450 of the benefits in gross income (1/2 ($32,900 − $32,000)).
Example (2): If S and D’s combined Social Security
benefits were $5,000, and their income plus half their benefits were $40,000,
they would include $2,500 of the benefits in income: 1/2 ($40,000 − $32,000)
equals $4,000, but 1/2 the $5,000 of benefits ($2,500) is lower, and the lower
figure is used.
3. If your income plus half your benefits exceeds $44,000 ($34,000
for single taxpayers), the computation in many cases grows far more complex. Generally,
however, 85% of your Social Security benefits will be taxed if you fall into
this category.
Caution: If you aren't paying tax on your Social Security
benefits now because your income is below the above floor, or are paying tax on
only 50% of those benefits, an unplanned increase in your income can have a
triple tax cost. You'll have to pay tax (of course) on the additional income,
you'll also have to pay tax on (or on more of) your Social Security benefits
(since the higher your income the more of your Social Security benefits that
are taxed), and you may get pushed into a higher marginal tax bracket. This
situation might arise, for example, when you receive a large distribution from
a retirement plan (such as an IRA) during the year or have large capital gains.
Careful planning might be able to avoid this stiff tax result. For example, it
may be possible to spread the additional income over more than one year, or
liquidate assets other than an IRA account, such as stock showing only a small
gain or stock whose gain can be offset by a capital loss on other shares. If
you should need a large amount of cash for a specific purpose, we would be
happy to help you determine what your additional tax cost will be before you
liquidate any assets.
If you know your social security benefits will be taxed, you can
voluntarily arrange to have the tax withheld from the payments by filing a Form
W-4V. Otherwise, you may have to make estimated tax payments.
