An effective 47 percent federal rate inside the range, and an 11,000 deferral that recovers 5,170: the GF592 Unit 4 phaseout calculation, worked for a composite couple paying two tuitions. Searches like "gf 592 unit 4 assignment example", "gf592 unit 4 sample" and "gf592 unit 4 example" land here.
What a finished GF592 Unit 4 phaseout calculation looks like
Three pages: the phaseout computation, a marginal-rate schedule and a planning page. The computation takes the couple's 171,000 against a range of [160,000] to [180,000] for joint filers in the tax year the prompt names. They are 11,000 into a 20,000 range, so 55 percent of each 2,500 credit disappears, leaving 1,125 per student and 2,250 in total. The marginal-rate schedule shows what one more dollar does: 22 cents of income tax plus 25 cents of lost credit, since two credits shrink by 5,000 across 20,000 of income, for a 47 percent federal rate, 52 with state tax. The planning page proposes 11,000 of additional pre-tax 401(k) deferral, which returns modified adjusted gross income to 160,000, restores 2,750 of credit and saves 2,420 of income tax.
How a GF592 Unit 4 example is structured
The calculation moves from definition to fraction to rate to action. It opens by defining the income measure the credit uses, because modified adjusted gross income for this credit is not the same figure as taxable income, and deferrals reduce it while itemized deductions do not. The fraction follows in one line: distance into the range over the width of the range. Each credit is then reduced and the refundable [40] percent portion recomputed, since the reduction applies to both parts. The marginal-rate schedule is drawn as a step chart from 150,000 to 190,000: 22 percent below the range, 47 inside it, 22 again above it. The planning page prices the one action that moves the couple out of the range, with the deferral room confirmed from pay stubs, and states the result as a rate: 47.0 percent saved on every deferred dollar.
The measure the credit uses
Modified adjusted gross income governs the phaseout, so pre-tax deferrals reduce it while itemized deductions and other credits leave it untouched.
Fifty-five percent gone
Eleven thousand into a twenty-thousand range removes 55 percent of each credit, leaving 1,125 per student, 450 of it refundable.
A rate the bracket table hides
Two credits shrinking by 5,000 over 20,000 of income add 25 points to the 22 percent bracket, for 47 percent federal.
A step chart of the next dollar
Plotted from 150,000 to 190,000, the rate climbs to 47 inside the range and falls back to 22 above it.
One deferral, priced as a rate
Deferring 11,000 restores 2,750 of credit and saves 2,420 of tax, 5,170 in all, which is 47.0 percent of the amount deferred.
Where marks go in GF592 Unit 4
Reporting the credit's reduced amount without the marginal rate it creates misses the unit's reason for existing, and graders deduct for that more often than for arithmetic slips. Credit follows the correct income measure named and computed, the fraction shown, the refundable portion recomputed, and a rate stated for the next dollar. Using taxable income instead of modified adjusted gross income is a common and disqualifying error, since it changes whether the couple is in the range at all. Planning suggestions that would not move the measure, such as more itemized deductions, show the definition was not read. Thresholds should carry brackets or a named year. Strong calculations also confirm the proposed action is available, here that deferral room exists under the plan's limit.

GF592 Unit 4 questions, answered
Why does a phaseout raise the marginal rate?
Because each extra dollar of income now does two things: it is taxed at the bracket rate and it reduces a benefit. In the sample, each dollar costs 22 cents of tax and 25 cents of lost credit across two students. Stating that combined figure is what turns a phaseout from a footnote into a planning fact the family can act on.
Which actions reduce modified adjusted gross income?
It depends on the credit's definition, which the calculation should quote. For many individual credits, pre-tax retirement deferrals, health savings account contributions and certain above-the-line deductions reduce it, while itemized deductions do not. The sample uses a 401(k) deferral because the couple has room under the plan limit and the deferral also saves income tax.
Should the calculation cover more than one phaseout?
If the fact pattern crosses more than one range, yes, because rates stack. A couple inside two phaseouts at once can face a marginal rate well above any bracket. The sample's couple sits inside only the education credit range, so the calculation says so and notes which other ranges it checked and cleared.
