What the New Democratic Congress Could Change on Your 2027 Taxes, and What It Can’t

Key Takeaways

Democrats won both chambers on November 3, 2026, and take control on January 3, 2027.
Nothing changes until a bill passes both chambers and President Trump signs it or Congress overrides a veto.
The child tax credit rises to $2,300 per child for 2027 under current law; Democrats want $3,000 or more.
Your 2026 return, filed in early 2027, follows today's rules, including the tips and overtime deductions.

Democrats resoundingly won control of both the House and the Senate in the latest midterm election cycle and will run the new Congress from January 3, 2027.

That doesn’t change your taxes on its own. President Trump still signs or vetoes every bill, and the new majorities are well short of the two-thirds needed to override a veto.

So here’s how I’d sort it: what’s locked in for the return you file next spring, what Democrats want to change, and what would actually have to happen first.

What’s Locked In for Your 2026 Return

The return you file in early 2027 covers 2026, and the rules for it are already set. Congress rarely changes a tax year after it ends, so I’d plan on these:

Child tax credit: $2,200 per child, with up to $1,700 of it refundable. See more on the CTC.
Earned income tax credit: up to $664 with no children and up to $8,231 with three or more. See more on the EITC.
New deductions: the tips, overtime, car loan interest and $6,000 senior deductions from the One Big Beautiful Bill (OBBBA) still apply. They run through 2028 under current law.
ACA premium credits: the enhanced version expired at the end of 2025, so 2026 coverage uses the older, smaller credits.

If you’re filing next spring, none of this election news changes what you claim. The IRS has also published its 2027 inflation figures (November 5, 2026), so under current law 2027 brings a $2,300 child tax credit with up to $1,800 refundable, and an EITC of up to $685 with no children or $8,496 with three or more.

What Democrats Want to Change

Most of the Democratic tax agenda goes back to the temporary 2021 rules, when the child tax credit and EITC were much bigger for one year. Tax Foundation’s rundown of the new Congress lists the main pieces:

Item	Current law (2027)	2021-style version
Child tax credit, ages 6-17	$2,300	$3,000
Child tax credit, under 6	$2,300	$3,600
Refundable portion	Up to $1,800	All of it
Childless EITC (max)	$685	$1,502
ACA premium credits	Original, smaller credits	Enhanced credits restored

The 2021 child tax credit also came as monthly advance payments, $300 a month per child under 6, per the IRS.

Here’s what that could mean in dollars.

Maria and Ben earn $60,000 and have kids ages 3 and 8. Under current law for 2027 they get $4,600 ($2,300 each). Under 2021-style rules, they’d get $6,600 ($3,600 plus $3,000), so $2,000 more.

The bigger change is for families who owe little or no tax. Under current law, they can get at most $1,800 per child back as a refund for 2027 ($1,700 on the 2026 return), and less at low earnings.

Full refundability would pay them the whole credit.

For workers without kids, the EITC would jump from a $685 maximum for 2027 to $1,502 under the 2021 rules, which also opened it to younger and older workers.

How Democrats Would Pay for It

None of this is cheap. The Congressional Budget Office estimated that making the enhanced ACA credits permanent would cost about $350 billion over 10 years. Tax Foundation puts a full return to the 2021 child tax credit at more than $500 billion.

The ideas Democrats have floated to cover it fall mostly on corporations and high earners:

Raising the 21% corporate tax rate
A surtax on income above $1 million
Higher tax rates on capital gains

For most of my readers earning under $100,000, the pay-for side wouldn’t touch your return directly. The credit side is what would.

Why None of This Is a Done Deal

A bill needs to pass the House and Senate and then get the President’s signature. If Trump vetoes it, Congress needs two-thirds of both chambers to override, and the new majorities aren’t close to that.

That makes 2027 a negotiation. The most likely leverage point is the next fight over the debt ceiling, which I expect sometime in 2027. My debt ceiling timeline has where that stands.

Republicans also have something they want. The tips, overtime and senior deductions expire after 2028, and Tax Foundation estimates extending them would cost about $577 billion. A trade between their priorities and Democrats’ credits is the kind of deal I’d watch for, but no deal of any kind exists yet.

Mistakes I’d Avoid While Congress Fights It Out

Planning your budget around a bigger credit. Proposals aren’t law. Until a bill is signed, plan on $2,200 per child for your 2026 return and $2,300 for 2027.

Changing your withholding for a proposal. Adjust your W-4 for your real situation, not a bill that may never pass.

Expecting monthly child tax credit checks in January. The 2021 monthly payments ended years ago. Any new version would need a new law and months of IRS setup.

Falling for “claim your new credit” messages. Scammers jump on news like this. The IRS doesn’t text or email you to claim a credit, and any real change would show up on IRS.gov first.

What I’m Watching in 2027

These are the dates and signals I’ll track, and I’ll update this page as each one lands:

Done, November 5, 2026: the IRS’s 2027 inflation figures set next year’s child tax credit at $2,300, the EITC at up to $8,496 and new brackets under current law.
January 3, 2027: the new Congress is sworn in, and the first tax bills get filed.
2027: the debt ceiling fight and the yearly budget, the two most likely places for a tax deal.
The ACA premium credits: whether Congress restores the enhanced version for 2028 coverage, since 2027 open enrollment is already underway.

Each January, when a new session starts, I’ll refresh this post with what passed, what stalled and what’s next.

Frequently Asked Questions

QWill the child tax credit increase in 2027?

AYes, a little, even without a new law: the IRS's inflation adjustment raises it to $2,300 per child for 2027, with up to $1,800 refundable. A bigger jump, like the $3,000 ($3,600 for kids under 6) Democrats have pushed for, would need Congress to pass a bill and the President to sign it, and no bill has passed.

QDoes the Democratic win change my 2026 tax return?

ANo. The return you file in early 2027 covers 2026, and its rules are already set, including the $2,200 child tax credit and the tips, overtime and senior deductions.

QCan Democrats pass tax changes without President Trump?

AOnly by overriding a veto, which takes two-thirds of both the House and Senate. The new majorities are well short of that, so any tax change would most likely need a deal the President agrees to.

QWill the expanded ACA premium tax credits come back?

AIt's possible, but not yet. The enhanced credits expired at the end of 2025. Restoring them permanently would cost about $350 billion over 10 years, per CBO, and would need to pass Congress and be signed.

QWhen would any new tax changes take effect?

AIt depends on the bill. A law passed in 2027 would most likely apply to 2027 or later tax years, so you'd usually see it on the return you file in 2028.
