The $10,200 Unemployment Exclusion Arrived Mid-Season: Who Should Wait, and Who Still Has to Act

Key takeaways

• ARPA § 9042 added IRC § 85(c): for tax year 2020, up to $10,200 of unemployment compensation is excluded from income if modified AGI is under $150,000 — $10,200 per spouse on a joint return.
• The $150,000 limit is a hard cliff at every filing status, and one dollar over it eliminates the entire exclusion. For the cliff test, all unemployment compensation is subtracted from the MAGI figure.
• The IRS has announced (IR-2021-71, March 31, 2021) that it will refigure affected returns automatically — refunds expected to start in May — so most taxpayers who already filed should not amend for the exclusion itself.
• An amended return is still needed where the lower income newly qualifies a taxpayer for a credit not claimed on the original return, such as the Earned Income Tax Credit.

What the provision does

ARPA § 9042 added a special rule to IRC § 85(c). For tax year 2020 only, a taxpayer whose modified adjusted gross income is less than $150,000 may exclude up to $10,200 of unemployment compensation from gross income. On a joint return where both spouses received unemployment, the exclusion applies separately to each — up to $20,400 combined.

Two features of the threshold control who benefits, and both are easy to get wrong:

First, the $150,000 ceiling is a cliff, not a phase-out, and it does not double for married couples. A household at $149,999 gets the full exclusion; a household at $150,000 gets none. There is no graduated reduction in between. That makes the line unusually consequential — a small amount of additional income can cost a married couple the entire $20,400 exclusion.

Second, the income measured against that ceiling is computed by subtracting the unemployment compensation itself. For the $150,000 test, a taxpayer removes the full amount of unemployment benefits — not just the $10,200 — from the modified-AGI figure. (The IRS clarified this reading in its updated worksheet on March 23; an earlier version had left the benefits in.) The practical effect is favorable: a household with, say, $158,000 of total income that includes $15,000 of unemployment compensation tests at $143,000 for the cliff and qualifies. Anyone modeling eligibility on total AGI without backing out the benefits will misjudge it.

The mid-season problem

The structural difficulty here is timing. The filing season opened February 12. ARPA was signed March 11. By then a large share of taxpayers who received unemployment in 2020 had already filed returns that reported those benefits as fully taxable. The law changed the answer after the fact.

That is what makes the IRS's chosen response notable. Rather than asking tens of millions of people to file amended returns, the IRS announced on March 31 (IR-2021-71) that it will recalculate the affected returns itself and issue refunds or apply the reduction to outstanding balances, with the first refunds expected in May and the work continuing through the summer. The agency plans to handle simpler cases first and more complex returns — including joint filers eligible for the full $20,400 — in a later phase.

For most taxpayers who already filed, the instruction is therefore counterintuitive but correct: do not amend for the exclusion. Filing an amended return for something the IRS is already going to fix automatically adds processing friction and risks crossing the automatic adjustment in the system.

When an amended return is still required

Automatic recalculation is not a complete remedy, and this is the part that gets missed. The IRS will refigure the tax on the income as already reported and apply the new exclusion. It will not go looking for credits a taxpayer never claimed.

So the exclusion can lower a household's income enough to newly qualify it for an income-tested benefit — and capturing that benefit requires an amended return. The clearest example is the Earned Income Tax Credit: a taxpayer who was over the EITC income limit with unemployment counted as income may fall under it once $10,200 (or $20,400) comes out, but the credit will not appear unless the taxpayer claims it. The same logic applies to other income-sensitive items a lower AGI can unlock.

The dividing line for already-filed taxpayers is therefore:

• The exclusion only changes the tax on income you already reported — do nothing; the IRS will adjust it automatically.
• The exclusion newly makes you eligible for a credit or deduction you did not claim — file an amended return to claim it.

For taxpayers who have *not* yet filed, the path is simpler: the IRS has updated its worksheet and instructions so the exclusion is computed correctly on an original return. There is no need to file first and amend later.

Two cautions worth stating plainly

First, do not double up. A taxpayer who has already filed an amended return to claim the exclusion should not file a second one when the automatic adjustments roll out. One correction is enough.

Second, keep the exclusion separate from the filing-deadline relief that arrived the same week. The IRS postponed the 2020 individual filing and payment deadline to May 17 (IR-2021-59, March 17), but that postponement is a different action with different scope — and, notably, it did not move the April 15 due date for first-quarter 2021 estimated payments. The two developments landed together and are easy to conflate, but they answer different questions.

What to do now

For households that received 2020 unemployment, the work is a short decision tree. If the return is not yet filed, compute the exclusion on the original return using the current worksheet and back out all unemployment compensation for the $150,000 cliff test. If the return is already filed and the exclusion merely reduces tax on reported income, wait for the automatic adjustment rather than amending. If the return is already filed and the lower income opens a credit — EITC most commonly — prepare an amended return to claim it. And in every case, respect the cliff: for couples near $150,000, the difference between qualifying and not is the entire exclusion, which makes the modified-AGI computation worth doing carefully rather than by eye.

FAQ

If I already filed, do I need to amend my return for the exclusion? Generally no. The IRS announced it will recalculate affected returns automatically and issue refunds beginning in May. Amend only if the lower income newly qualifies you for a credit you did not claim.

Is the $10,200 per return or per person? Per person. On a joint return where both spouses received unemployment, each can exclude up to $10,200, for as much as $20,400 combined — provided household modified AGI is under $150,000.

Does the $150,000 limit phase out gradually? No. It is a hard cliff and it is the same for all filing statuses. At $150,000 or more of modified AGI, the exclusion is zero. For the test, all unemployment compensation is subtracted from the MAGI figure.

What if the exclusion makes me eligible for the EITC? Then file an amended return. The automatic IRS adjustment recomputes tax on income already reported; it does not add credits you did not originally claim.
