Americans won't see the effects of tax reform until spring 2019.

• President Donald Trump's new tax plan will take effect on January 1, 2018 if Republicans get it done.
• Americans won't see the change to their tax returns until spring 2019 - when they'll be filing taxes for 2018.
• This means tax reform will go into effect after the 2018 mid-term elections.

President Donald Trump has said he wants tax reform on his desk by Christmas.

And Republicans appear to be on track to getting that done. The House passed its version of the Tax Cuts and Jobs Act two weeks after coming out with their proposal in November. The Senate, meanwhile, pushed its version through just after 2 a.m. ET on December 2.

Negotiators now need to work out significant differences between the two versions of the bill, and then pass the updated bill in both chambers.

If the House and the Senate manage to do that, and Trump signs the bill before the end of the year, the bill will go into effect on January 1, 2018.

But regular Americans won't feel the effects of tax reform until spring 2019, when they'll be filing taxes for 2018. That means people won't see changes to their tax returns until after the 2018 mid-term elections.

If the House and Senate don't manage to get an updated bill on Trump's desk before the end of the year, but do get things done in early 2018, then the bill could be made retroactive. That just means it would count as if it went into effect on January 1, 2018, so Americans would also see the effect in 2019.

And just as a reminder: folks will be filing taxes for 2017 this upcoming spring. Taxes are due on April 17, 2018.

We'll update this post if there are changes as Congress moves closer to passing the Tax Cuts and Jobs Act.
