There's 2 parts to this:
-No unemployment income is counted to calculate the $150k UI deduction threshold
-for stimulus, final AGI is used, which includes all unemployment income less the $10,200 deduction
OK, let's try this again.
Couple made $170,399 including $20K/spouse unemployment.
MAGI=$170,399-$40,000=$130,399. Qualified for unemployment exclusion
Taxable income=$170,399-$20,400=$149,999. Qualified for stimulus
Couple made $170,399 including $40K unemployment for one spouse only.
MAGI=$170,399-$40,000=$130,399. Qualified for unemployment exclusion
Taxable income=$170,399-$10,200=$160,199. Unqualified for stimulus
Couple made $181,399 including $20K/spouse unemployment.
MAGI=$181,399-$40,000=$141,399. Qualified for unemployment exclusion
Taxable income=$181,399-$20,400=$160,999. Unqualified for stimulus
Couple made $181,399 including $5K for Spouse A and $15K for Spouse B in unemployment.
MAGI=$181,399-$20,000=$161,399. Unqualified for unemployment exclusion
Taxable income=$181,399-$0=$181,399. Unqualified for stimulus
Couple made $190,399 including $20K/spouse unemployment.
MAGI=$150,399=Unqualified for unemployment exclusion
Taxable income=$190,399-0=$190,399. Unqualified for stimulus.
Or in the last 2 scenarios does the stimulus test still ignore the $10,200 despite it being unqualified for the tax exclusion? In other words should there be a separate calculation for Final AGI for the stimulus test and actual taxable income?
