For the 2018 tax year, the IRS shortened the 1040 tax return, eliminated the 1040EZ and 1040A versions, and added six new schedules to handle the information that moved off the main tax return form.
When introduced, IRS Schedule 2 included just four lines:
- Reserved lines: Listed as one line on the form, several line numbers were reserved for future use and were unnecessary for filing a 2018 tax return.
- Alternative minimum tax: If you owed alternative minimum tax, this line is where you recorded the amount. You also had to complete Form 6251 to calculate your AMT and attach the form along with Schedule 2 to your 1040.
- Excess advance premium tax credit repayment: Filers who received an advance premium tax credit for health insurance purchased through the health insurance marketplace had to file Form 8962, premium tax credit, to reconcile how much they received with how much of the refundable credit they qualified for. If they received too much, they entered the excess amount on Line 29 of that form and then brought the amount over to Line 46 of IRS Schedule 2.
On the final line, you entered the sum of amounts from the other lines. Then that amount went on Line 11 on your Form 1040.
