The look-back is a complex area of tax law that can cause compliance errors
and missed opportunities. Filed on IRS Form 8697, “Interest Computation
Under the Look-Back Method for Completed Long-Term Contracts,”
the look-back is a hypothetical recalculation of a contractor’s taxable
income based on the actual performance of its completed jobs.
Look-back does not result in an adjustment to the contractor’s previously
reported taxable income or require an amended return. It does, however,
result in the refund or payment of interest depending on the accuracy of the
contractor’s applicable job estimates. Contractors assessing their business
opportunities and risks related to look-back compliance should consider the
answers to the following questions about requirements and standards.
Which contractors are subject to look-back?
Any contractor that has long-term contracts with a requirement to
report income on the percentage of completion under Internal Revenue
Code (IRC) Section 460 is required to comply with the look-back
rules.
The IRS devotes an entire chapter of its “Construction Industry
Audit Techniques Guide” to look-back compliance. Nevertheless, the
requirements frequently are paid little attention or ignored completely.
The statute of limitations for look-back refund claims generally is six years from
the due date of the tax year in which the job closed. Many contractors subject
to look-back have received look-back refunds in the six-figure to seven-figure
range— including those with experienced significant fade on large multiyear jobs.
Which jobs are subject to look-back?
The application of look-back is determined on a contract-by-contract basis.
To be subject to look-back, a contract must meet the requirements of a
long-term construction contract under IRC Section 460.
Contracts started
and completed during the same tax year are not considered long-term
construction contracts. The tax rules for determining the completion date of
a contract differ from U.S. generally accepted accounting principles (GAAP)
rules, often resulting in an earlier completion date for tax purposes.
Additionally, even if a contractor has long-term construction contracts, there
are additional exemptions to look-back applicability, including the following:
â– â– Home construction contracts.
â– â– Contracts started in a year during which the contractor qualified as a small
contractor.
Generally, this includes contracts estimated to be completed in
two years and started during a year in which the contractor’s average gross
receipts for the three preceding tax years did not exceed $10 million.
â– â– Small contracts that have a gross contract price less than the lesser of $1 million
or 1 percent of the contractor’s gross receipts for the prior three tax years.

. Tips and Traps for
Look-Back Computation
â– â– Contracts for which an election not to apply look-back applies. The IRC provides
a permanent and binding election not to apply look-back on contracts with
a gross profit that does not vary more than 10 percent from the gross profit
estimated in each of the prior tax years. This election may be valuable for large
contractors who typically experience slight pickup on their jobs. However, the
election actually increases the compliance costs of look-back requirements.
How is the look-back calculation applied?
If a contractor determines it is subject to look-back requirements and has
jobs that are subject to look-back requirements, it is required to perform the
look-back calculation.
It is important for contractors to apply look-back based
on the tax treatment of determining gross profit on their jobs and not GAAP.
Many contractors use the percentageof-completion method for GAAP,
but percentage of completion is
different for tax purposes. There are
additional tax adjustments such as
depreciation and reserves embedded
in the GAAP calculation that are not
deductible for tax purposes. Some
payables that are embedded in the
GAAP calculation have not met the
all-events test required for inclusion
in the tax calculation.
Finally, the 10
percent method, if elected, must be
addressed in the look-back calculation.
Contractors subject to
look-back requirements
are required to perform the
look-back calculation.
Additional Look-Back Opportunities and Pitfalls
â– â– The applicable interest rate used to compute the payment or
refund due is redetermined on the anniversary of the tax return
due dates. Also, a different interest rate applies to C corporations
on recalculated income amounts exceeding $10,000.
â– â– The election of the simplified marginal impact method does not require taxpayers
to recalculate their hypothetical taxable income for previous tax years. Rather, the
highest assumed marginal tax rate for a C corporation is applied to the calculated
change.
The method is beneficial for nonclosely held S corporation shareholders
and partners who are required to file the look-back as individual taxpayers.
â– â– The impact of post-completion additional income or expenses on
previously reported look-back filings should be properly addressed.
Possible large refunds may result for contractors with significant
rework requirements, claims paid, or change orders denied.

Compliance with the look-back requirements is very cumbersome and,
depending on facts and circumstances, the cash-flow effect can be significant.
Contractors should consider whether their systems and processes are
adequate to capture and organize the necessary data to comply.
