2018 Federal Income Tax Changes and How They’ll Impact You

2018 federal income tax changesInstead of paying $7,500 in Federal taxes like we did this year, we’ll only owe $3,000 next year with the new income tax changes. Maybe even less. BOOM!! So what is it about the 2018 federal income tax changes that reduced my tax bill so much? And what will the changes do to yours? Let’s dig through the new tax policies and see how they’ll impact you.

The 2018 Federal Income Tax Changes and How They’ll Impact You

Today is April 9th. Hopefully by this point you have your 2017 taxes taken care of. (If not…you might just want to stop reading this post and take care of your looming deadlines instead…) So let’s start thinking about next year’s filings. How will they be different, and what should we expect in terms of tax amounts owed?

A Quick Summary of the Changes

Mainly, the news media has focused in on the tax bracket changes for 2018, but there’s way more going on that you should know about…about six more things to be exact. Here’s the run-down.

  1. Income tax bracket changes
  2. Standard deduction increase
  3. No more child exemptions
  4. Increased child credit
  5. Decrease in the medical expense deduction
  6. Penalty removal from Obamacare
  7. Tax bill expiration

I told you there was a lot going on. So let’s learn about the federal income tax changes, and then apply them to your situation to see how your taxes will  be impacted this year vs. last year.

1) Income Tax Bracket Changes

For most of us, the updated 2018 tax bracket will put more money in our pockets. For only a handful of higher income earners, taxes may be slightly more. Take a look at the tables below. They show the side-by-side comparison of the old income tax brackets from last year and the new ones from this year.

federal income tax changes - married filing jointly

As you can see, most will pay a reduced tax percentage and, according to, will pay an average of $1,200 less each year. Liz and I will likely land in the 2nd row of the married filing jointly table, so we’ll save 3% of that bracket total, or roughly $1,700! Lucky us!

What about he unlucky ones? Who are they?

Take a look at the single filing bracket. Someone that earns $400,000 a year used to be taxed in the 33% tax rate. Under the new tax laws, this individual will be landing pretty heavily in the 35% tax bracket. But, since all the steps leading up that point are a savings, their increased tax payment is actually pretty minimal. Instead of paying $115,399 of taxes on that $400k income like they did in 2017, they’ll now owe $115,689. So yes, they’ll pay more, but just barely…

2) Standard Deduction Increase

According to the Joint Committee on Taxation, just 6% of of taxpayers will itemize their taxes next year compared to 30% from this year.

Why the big falloff? Simple – it’s due to the new standard deduction rates.

As you can see in the table above, the standard deduction rates have increased dramatically from 2017 to 2018. If you’re not familiar, this is simply the amount that you automatically get to take off your total earnings for the year. If you earn $100,000 as a married couple, you would have received a $13,000 deduction in 2017 and would have only had to pay tax on an income of $87,000. This year though, you’ll have a standard deduction of $24,000 and will therefore only have to pay tax on $76,000! Works for me!!

For the people that used to itemize their taxes (ie. add up their interest paid, their state taxes paid, and add up all their charitable donations), the standard deduction is now likely bigger than all their itemized amounts combined (which is why so few people will itemize this next year)! This is great for most, but if you used to give money away because of the tax break, that’s no longer a valid reason.

Oh, and for all of you that tell me you have a mortgage as a tax deduction, that’s complete B.S. now, so stop talking about it! 😉

3) No More Exemptions

The first two bullets were a benefit to most. This one is not.

In 2017, everyone received a $4,050 exemption for each person living in the house. Let’s say you’re married and have three kids. You’d receive $20,250 in exemptions, meaning that you wouldn’t have to pay taxes on $20,250 worth of your income. Pretty sweet deal, right?

Well not anymore.

Starting in 2018 with the new income tax changes, the tax exemptions are going away. That $20,250 exemption that you got in 2017 suddenly becomes $0 in 2018.

But, there is a silver lining to this one. Check out the next point.

4) Child Credit Increased from $1k to $2k

This one is huge for Liz and I – especially since we’re expecting in September! Instead of getting $1,000 taken off our tax bill like we did this year, we’ll be able to subtract $4,000 from our taxes owed in 2018!

In case you don’t understand how huge this is, let me explain.

In tax change #3 above, we mentioned that the child exemptions went away (womp wommmm). But, if you were married and had a household income of $75,000 last year, this would have only saved you from paying a 15% tax on $4,050 worth of income, or $607. This year, instead of saving $486 (12% of the $4,050 exemption), you’re getting $1,000 subtracted off your total taxes owed! BOOM!!

I don’t know about you, but I’d rather have the additional $1,000 in tax credit per kid!

5) Decrease in the Medical Expense Deduction

For some of us, maxing out our health insurance each year is just the norm. It’s not ideal, it’s not fun, but it’s a reality. Chances are that your life is absolutely no fun right now, but hopefully this will help.

In 2017, you had to pay out more than 10% of your adjusted gross income (AGI) in medical bills to start getting the medical expense deduction. This year, the medical expense deduction starts kicking in at just 7.5% of your AGI.

Okay, I know…it’s not the most exciting news in the world, but it will help you to keep some more money in your pocket, so I’d call it a win!!

6) Penalty Removed from Obamacare

Remember when Obamacare got so many sign-ups for insurance? That’s because it was a great deal for everyone, right?

Ummmm, not quite.

The reason so many people signed up was because they’d be penalized if they didn’t. The recent tax update removed this penalty, so if you don’t want medical insurance (which by the way…you really should have insurance), you won’t have to pay to be excluded.

7) These Laws Expire in 2025

If you love the new income tax changes, don’t get too attached. They’re set to expire in 2025. Be ready for a new round of crazy once we get there. Heck, maybe Jim Carrey will be President! Wait, no…he’s Canadian. Scratch that.

The 2018 Federal Income Tax Changes – In Summary

From a personal finance standpoint, I’m pretty happy with the income tax changes. After all, I’m saving about $4,500 every year!! But, from the standpoint of a U.S. citizen that’s concerned about our national debt, it does concern me a bit. Hopefully the government is able to cut out a lot waste, stop funding senseless programs, and inspire people to start funding things they believe in again (rather than just trying to get the government to do all the dirty work). Buuuut, more than likely nothing will change and we’ll all just quietly go deeper and deeper into the national debt abyss.

What’s your take on the new income tax changes? I bet there’s a ton of opinions out there. I want to hear them all!

Are you saving a bunch of money with the income tax changes? Is there anything that you don’t like about them?

Money Save Money


My name is Derek, and I have my Bachelors Degree in Finance from Grand Valley State University. After graduation, I was not able to find a job that fully utilized my degree, but I still had a passion for Finance! So, I decided to focus my passion in the stock market. I studied Cash Flows, Balance Sheets, and Income Statements, put some money into the market and saw a good return on my investment. As satisfying as this was, I still felt that something was missing. I have a passion for Finance, but I also have a passion for people. If you have a willingness to learn, I will continue to teach.


  1. The new tax law will definitely cost us more. Our itemized deductions are more than the new standard deduction so we will lose about 4K. Then when you take away the exemptions we lose more. Both my hubby and I are ove65 so we lose that extra as well. Personally, I wish they’d simply lowered the tax rates, but even though we pay more, I’m still in favor of the tax cut. Any time the majority of the population get to keep their own money away from the government, I’m in favor of that.

    • How much more do you figure you’ll be paying? You’re definitely a rare case.

    • Why can’t you itemize?

      If your itemized deductions are greater than the govt standard then go ahead and itemize.

      • Jim I should have said that our itemized deductions are CURRENTLY more. Two things occur to change that under the new law. First, our real estate taxes exceed the new limit of $10,000. So we lose about $4,000 under the new law. Secondly, our medical deductions will be similarly capped raising the excess over 7.5% to an excess over 10%. Add those losses to the already mentioned exemption loss, we now can’t no longer beat the standard deduction.

  2. Our estimate is between $1,000 – @2,000

    • Doh! Well, between the two of us, we’re still saving money! 😉

  3. Well our child aged out of the child tax credit this year so we automatically pay $1000.00 more. I wish they would have extended that age to 18

    • Bummer. You just missed out on $2,000 instead of $1,000…

  4. My wife and I will be making approximately $26,000.00 this year (2018) so if I understand with the standard deduction of 24,000.00 are reportable taxable income will only be $2,000.00. is this correct? Also is the standard deduction for 2019 going to be the same?

    • Hi Pete. Yes, and yes. If you have paid anything in taxes throughout the year, you will likely get a tax refund. Are you working to increase your income! I imagine it’s tough to live on just $26k a year!

  5. Senior with Medicare and pension, along with owning two family home with income from half that house. Do I still have to file a separate form for the income from that rental? Are any of the expenses and repairs still deductible from that income on rental?

    • Hi Carole. If you earn any sort of income, it should be reported at tax time. So, yes, you should file this income. If you DO file, then yes, you can deduct repairs, mileage, office space, depreciation etc. from your rental property. Your tax professional should be able to help you with this. Best of luck to you!!
