The Child Tax Credit and the Additional Child Tax Credit are two connected parts of the same tax break, but they work differently in how they reduce your tax and how much you can get back as a refund.

Big-picture difference

  • Child Tax Credit (CTC)
    • Nonrefundable credit that reduces the income tax you owe, sometimes down to zero but not below.
* For recent years, it’s been up to about 2,000 per qualifying child, subject to income limits and phaseouts.

* If your tax bill is already small or zero, you may not be able to use the full CTC.
  • Additional Child Tax Credit (ACTC)
    • Refundable portion of the Child Tax Credit; think of it as the “leftover” part that can be paid out to you as a refund when you can’t use all of the CTC.
* You can receive money back even if your tax liability is already reduced to zero, up to a per‑child limit (for example, around 1,600–1,700 per child in recent years, depending on the year and inflation rules).

* Usually requires at least a minimum amount of earned income (around 2,500 or more) and still follows income phaseout rules.

How they interact in practice

Imagine you qualify for 2,000 of Child Tax Credit for one child:

  1. The CTC is applied first to cut your tax bill.
  2. If your tax bill is bigger than the credit, the entire 2,000 just reduces your tax, and you don’t need ACTC at all.
  1. If your tax bill is smaller (say you only owe 800), the CTC can only wipe out that 800. You now have 1,200 of “unused” credit.
  1. If you meet the income rules, some or all of that 1,200 may be paid to you as Additional Child Tax Credit, subject to that year’s per‑child limit.

That’s why tax pros often describe ACTC as a backup or add‑on to the main Child Tax Credit.

Why this is a trending topic now

In the last few years, the Child Tax Credit has changed several times, including temporary expansions and later rollbacks, which has left a lot of confusion on forums and in news updates. People look up “what’s the difference between child tax credit and additional child tax credit” because:

  • Rules for the refundable portion keep shifting, especially as Congress debates changes near each tax season.
  • Many families with lower tax bills discover they don’t get the full CTC unless they also qualify for the ACTC.
  • Online tax software and tax pros often show both amounts on screen or on summaries, which prompts questions like the ones posted in personal finance forums.

A typical discussion thread will have someone noticing “Child Tax Credit” on one line and “Additional Child Tax Credit” on another, then asking why one is 0 and the other is positive; the usual answer is that their tax liability was already reduced to zero, so what remains shows up as a refundable ACTC instead.

Mini FAQ

1. Can you get both Child Tax Credit and Additional Child Tax Credit in the same year?
Yes. You can have part of your credit used as nonrefundable CTC (cutting your tax) and the rest paid out as refundable ACTC, as long as you meet the earned income and eligibility rules.

2. Do you have to file a special form?
Both pieces are calculated using Schedule 8812 (Credits for Qualifying Children and Other Dependents), which determines how much is CTC vs. ACTC on your individual tax return.

3. Does the difference change year to year?
The basic concept—CTC is nonrefundable, ACTC is refundable—stays the same, but the exact dollar amounts and formulas for the refundable portion can change with new legislation and inflation adjustments, which is why you’ll often see “latest news” articles about updated Child Tax Credit rules each filing season.
