Child Tax Credit income limit 2017 vs 2018

[tbt2018]

Did I read it right? For "Child Tax Credit", TurboTax tells me that:

For 2017: The child tax credit is reduced by $50 for every $1,000 that your adjusted gross income (AGI) exceeds these amounts:

  - Married filing jointly - $110,000

  - Single, head of household or qualifying widow(er) - $75,000

  - Married filing separately - $55,000

But for 2018: These credits are reduced by $50 for every $1,000 that your adjusted gross income (AGI) goes over these amounts:

 - Single, Married Filing Separately, Head of Household, or Qualifying Widow(er) - $200,000

 - Married filing jointly - $400,000

So for married jointly filling, the AGI limit is raised by almost 4 time??? (from $110K to $400K?) That sounds a lot so want to confirm.

Thanks!

Are you preparing a return for 2017--using the correct 2017desktop software?


CHILD TAX CREDIT  (2017 and before)
The child tax credit can only reduce your tax liability down to zero.  It is not a refund.  If you have no tax due, then you may not receive the full amount of the $1000 Child Tax Credit
If your child turned 17 at any time during 2017, then you will not receive the child tax credit.
If you are claiming the Child Tax Credit for a child who was born in 2017, make sure you said in Personal Info that the child lived with you all year and that you entered the child’s SSN.
The child tax credit is reduced by $50 for every $1000 of AGI over these limits:
Married filing jointly                                                            $110,000
Single, Head of Household or qualifying widower               $75,000
Married Filing separately                                                      $55,000
*You can see the amount of the child tax credit you got on your Form 1040A on line 35; on Form 1040 line 52
If you received the Additional Child Tax Credit Form 1040A line 43, Form 1040 line 67
