Need talk about unemployment tax break

Did you already file?  

If you have filed. The IRS will recalculate your return for the new 10,200 unemployment exemption for you. There is no need for taxpayers to file an amended return unless the calculations make the taxpayer newly eligible for additional federal credits and deductions not already included on the original tax return.

You can log back into your return and it should automatically update your return and show you the new refund.  But the updated return won't be sent.  The IRS will adjust it for you.

If you have unemployment you can exclude up to 10,200 for each person if your income is under $150,000.  Your unemployment compensation will be on Schedule 1 line 7.  The exclusion will be on Schedule 1 Line 8 as a negative number. The result flows to Form 1040 Line 8.
