What does the new Schedule 5 of the 1040 look like?
The Tax Cuts and Jobs Act changed the 1040 and many supplementary schedules were added. For tax year 2018 only, Schedule 5 was where the taxpayer's Other Payments and Refundable Credits was calculated.
Starting in tax year 2019, Schedules 3 and 5 are combined on to a single Schedule 3. Line numbers have also been rearranged.
Amounts on this schedule included the Net Premium Tax Credit from form 8962, amounts paid with extensions, excess social security, and tier 1 RRTA tax withheld.
