Schedule 3Additional Credits and Payments

15 — Total Schedule 3 Updated for tax year 2025

Does this apply to you?

  • You completed Schedule 3 and have amounts on line 7, line 14, or both
  • You have any combination of nonrefundable credits, refundable credits, or additional payments that require Schedule 3

Easy to overlook

The two parts go to different lines on Form 1040 Line 15 is an informational total — you do not transfer this combined number anywhere. 1 Part I (line 7) goes to Form 1040 line 20 as nonrefundable credits. Part II (line 14) goes to Form 1040 line 31 as other payments. Entering the line 15 total on either Form 1040 line overstates that line and understates the other. IRS Schedule 3 Instructions — Line 15

Schedule 3 must be attached even for a single credit If you claim even one credit that belongs on Schedule 3 — a foreign tax credit, an education credit, an extension payment — you must file the entire schedule. 2 Tax software handles this automatically, but paper filers sometimes enter the credit directly on Form 1040 line 20 or 31 without attaching Schedule 3. The IRS requires the schedule to substantiate the amounts. General filing pattern — Schedule 3 not attached when only one credit applies

Watch out for this

Transferring the line 15 total to a single line on Form 1040. The nonrefundable portion (line 7) and the refundable portion (line 14) serve different functions in the tax calculation. Nonrefundable credits reduce tax liability; refundable credits and payments can produce a refund. Putting the combined total on Form 1040 line 20 would overstate your nonrefundable credits, and putting it on line 31 would overstate your refundable credits.
