Permanent Differences
Definition:
Items of revenue or expense that are in book (or
taxable) income of a period, but never part of
taxable (or book) income.
2 types:
1. non-taxable revenues
2.
(ex. interest income on
municipal bonds)
non-deductible expenses (ex. GW amortization)
ex. E13-7 Exhibit 13.2, Pg. 690
Paul Zarowin

Importance of Permanent Differences:
Effective vs. Statutory Tax Rate
def: effective tax rate (ETR) =
tax expense
pre-tax (book) income
def: statutory tax rate (STR) = rate set by government



permanent diffs cause ETR  STR
non-taxable revenues lower the ETR
non-deductible expenses raise the ETR
ex. E13-7, E13-8 (Kent)
Paul Zarowin

Temporary (Timing) Differences
Temp. diff. cause deferred tax assets, liabilities, expense
Definitions:
 Temp diff: item of revenue or expense that are part of book and
taxable income, in different periods

Deferred tax asset: future tax deductible due to current timing

Deferred tax liability: future tax payable due to current timing
difference

Q: What is sum of temporary differences over firm’s life?

Components of Tax Expense and Tax JE
Components of tax expense: 1. current (pay now); and
2. deferred (paid before or after)
1.
DR current tax expensea
CR
Cash or taxes payable
Assumes positive
taxable income
a) Current tax expense = taxable inc.*current statutory tax rate
2.
DR deferred tax expenseb
CR
Deferred tax asset/liability
b) Deferred tax expense =
net  in deferred tax asset/liability

on net  deferred

c) Total tax expense = current + deferred

Deferred Tax Accounting =
Inter-period Tax Allocation
Total income tax expense =
Current (paid now)
+ Deferred (paid both before or after)
Paul Zarowin
16
Originating vs. Reversing Timing Diff.


Originating differences create deferred tax assets
(DR); and liabilities (CR)
Reversing differences reduce deferred tax assets (CR)
and liabilities (DR)
Paul Zarowin
17
Examples of Deferred Tax Assets/Liab
1. Installment sale; revenue is recognized up front
for financial reporting, but is recognized for tax
purposes later, when cash is received each period.
2. Prepayment; revenue is recognized for tax
purposes up front as cash is received , while accrual
accounting delays revenue recognition until revenue
is earned later.
3. Bad debts expense. The allowance method for
books recognizes the expense in the period of sale
by the adjusting entry (matching principle), while
the direct write-off method recognizes the expense
in a later period, when the receivable is actually
written off.
Paul Zarowin
18
Examples of Deferred Tax Assets/ Liab (cont’d)
4.

depreciation expense; firms use an accelerated
method for taxes and SL for books. This
combination recognizes some depreciation for taxes
first and for books later.
RCJ give additional examples of revenues and
expenses that produce deferred tax assets and
liabilities in Exhibit 13.1, Pg. 689-90.
Paul Zarowin
19
Calculation of Deferred Tax Expense,
Asset, Liability: B/S Method
1.
2.
deferred tax asset/liability = cumulative timing difference * STR
deferred tax expense = net  in deferred tax asset/liability
B/S method (also called asset/liability method)

use STR expected to be in effect when timing difference reverses

so, if STR changes, calculate deferred tax asset/liability as per
(2), and calculate deferred tax expense =  deferred tax
asset/liability
I/S method

for constant STR only,
deferred tax expense = current year’s timing difference * STR

B/S method is or constant or changing STR
ex. E13-3 different rates over time, vs.
E13-2 change in rates
Paul Zarowin
20
Deferred Tax Asset, Liability and Expense
Depend on Tax Rate
Key point:
Deferred tax asset, deferred tax liability and deferred
tax expense depend on the tax rate.
Ex. E13-8, E13-9, E13-10
Paul Zarowin
21
Intuition


Deferred tax asset =
$ amount of future tax deduction (or tax saving)=
$ timing difference * STR
Deferred tax liability =
$ amount of future tax payable =
$ timing difference * STR
Paul Zarowin
22
Net Operating Loss (NOL)
NOL = negative taxable income

Book income may be either positive or negative
NOL can be carried back or forward
NOL carryback:
Get a refund of past taxes paid:
DR cash or tax refund receivable
CR
(current) income tax expense
 The maximum carryback period is 2 years (offset the earlier
year first, as in FIFO)
Paul Zarowin
23
Net Operating Loss (cont’d)
NOL carryforward:
Offset future income (also FIFO), reducing future taxes payable:
DR deferred tax asset
CR
(deferred) income tax expense
This is another reason for deferred tax asset in addition to timing
differences.

A firm can carryforward an NOL for up to 20 years.
EX. E13-13, 14, 16
Paul Zarowin
24
Incentives for Carryback vs. Carryforward
1.
Can’t carryback because of 2 years of losses
2.
Time value of money: get the cash ASAP 
carryback
3.
If tax rates are expected to rise, a dollar of
deduction will be worth more  carryforward
ex. P13-7
Paul Zarowin
25
Deferred Tax Asset Valuation Allowance
Contra-asset account (CR balance on the B/S ; eg, acc’d
depreciation or AUA) that reduces the deferred tax asset to
its expected realizable value
1.
2.



Record the deferred tax asset in the usual way (as if there
were no valuation allowance)
Make an additional entry:
DR
(deferred) income tax expense
CR
deferred tax asset valuation allowance
increasing (decreasing) the allowance increases (decreases)
deferred income tax expense
allowance’s existence and magnitude reveals management’s
expectation of future earnings.
management can use changes in the allowance to manipulate
NI, by affecting income tax expense.
ex. E13-17
Paul Zarowin
