Even
though your annual revenues are less than $10 million, entitling you to
report your long-term contract revenues on the completed-contract
method, you may be subject to the alternative minimum tax on your
long-term construction contracts. The alternative minimum tax is
precisely what the name implies: it is another tax established to
ensure that your company pays at least some taxes every year.
Since the completed-contract method allows you to defer all taxable
income on contracts incomplete as of the year-end, it was considered a
tax preference item in the Tax Reform Act of 1986 and included as a
component in the calculation of alternative minimum taxable
income.
As long as your C corporation's average annual receipts do not surpass
$5 million in your first year of operations and $7.5 million in every
year thereafter, you do not have to worry about the AMT tax. But
once your average annual receipts exceed $7.5 million, then your C
corporation needs to compute the alternative minimum tax and determine
its additional tax liability--if any--over and above its regular
corporate tax.
Although small C corporations are exempt from the alternative minimum
tax, S corporations and partnerships are not. Even though they do
not pay taxes, the AMT adjustments from long-term contracts pass
through to the shareholders and partners, respectively, and would be
reported on their individual tax returns. Sole member limited
liability companies, sole proprietors, and individuals as shareholders
and partners would report the AMT adjustment from long-term contracts
on line 23 of Form 6251, Alternative Minimum Tax—Individuals, whereas C
corporations would report it on line 2f on Form 4626, Alternative
Minimum Tax—Corporations.
To compute your AMT preference amount from long-term contracts,
calculate taxable income on long-term contracts using the
percentage-of-completion method as described in the Internal Revenue
Code section 460(b), which requires that you determine each contract’s
percentage of completion by comparing costs to-date to total estimated
contract costs. Next compare the taxable income on all of your
long-term contracts based on the
percentage-of-completion method of accounting to the taxable income
based on the completed-contract method of accounting (or whatever
method used other than the percentage-of-completion method of
accounting). If taxable income is
greater under the percentage-of-completion method, enter the difference
as a positive amount on the long-term contracts tax preference line of
the AMT tax form; if taxable income is less under the
percentage-of-completion method, enter the difference as a negative
amount on that same line.
A simple example of the use of the completed-contract method for tax
reporting of long-term contracts will illustrate its impact on the
alternative minimum tax as well as the total tax liability of the
contractor. Assume a contractor has
taxable income of $100,000 by using the completed-contract method for
its long-term contracts. Now assume that if the construction
company had
used the percentage of completion method on its long-term contracts, it
would have reported an additional $175,000 in taxable income.
This additional amount of $175,000 is what the contractor would report
on line 2f on Form 4626 for the tax preference from long-term
contracts, as shown below.
As evident in lines 7 through 9, $40,000 of alternative minimum taxable
income not exceeding $150,000 is exempt from taxation; however, the
$40,000 exemption is phased out pro-rata over $160,000 above the
$150,000 AMTI threshold. Here, since $125,000 exceeds the
$150,000 limit for taking full advantage of the $40,000 exemption from
the alternative minimum tax, phasing out 78.125% of the full exemption,
only 21.875% of the $40,000 exemption, or $8,750, can be excluded from
alternative minimum taxable income in our example.
On line 12 is the "tentative minimum
tax", derived by taking 20% of the alternative minimum taxable income
after deducting any eligible exemption. At this point, the
contractor would compare this tentative minimum tax
(TMT) to the corporation's tax liability based on the regular tax
rules, excluding
the AMT calculation. Since TMT of $53,250 exceeds the
contractor's regular
tax liability of $22,250, the $31,000 excess is the construction
company's alternative
minimum tax, and would be added to the regular tax liability of
$22,250, for a total tax liability of $53,250. This $31,000 also
would be reported on Form 1120, Schedule J, line 3.
As you can see, the alternative minimum tax can mitigate the tax
benefits of the completed contract method, particularly if profits on
long-term
contracts are material and profits on other contracts are insignificant
in comparison. In our simple example, the alternative minimum tax
was 139.33% of our regular tax liability. Often contractors fail
to include the alternative
minimum tax on its long-term contracts in its estimates of taxes;
however, to do so could be fatal in terms of arranging sufficient cash
flow.
Hopefully this article has presented sufficient evidence to persuade
contractors and others that it is imperative to include the effects of
the
alternative minimum tax from long-term contracts in all tax planning
before year-end, otherwise the construction company may be in for an
unpleasant surprise upon the preparation of its tax return after the
end of the year.
