With all the changes tshutterstock_561409078 (002).jpgo our tax laws of late, it can be confusing knowing what to do right now to file your taxes this April. 


As we begin to get our first hint of spring here in San Antonio, it’s tempting to get out and enjoy the milder weather and watch the flowers bloom.  However, April 17th is approaching and many of you are starting to gather the strength to do your taxes for the 2017 tax year. Thanks to the calendar this year, we get two extra days beyond the traditional April 15th deadline to file income taxes.  It’s true that the Tax Cuts and Jobs Act (TCJA) brought about significant changes.


At USAA, we have provided guidance surrounding the tax changes and what it means to you over the last few weeks.  And now that it is time to actually file your taxes for the 2017 tax year, let’s get down to “brass tax” (pardon the pun).

The TCJA changed tax rates for 2018 and beyond. The TCJA lowers the marginal tax brackets applied to most Americans (10%, 15%, 25%, 28%, 33%, 35%, and 39.6%) with corresponding lower rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.  These relatively lower rates have been a welcome change for many allowing a bit more money in your paycheck this year.  It may feel like the TCJA has already changed many things, but keep in mind that when you’re filing your taxes, we are talking about 2017 and not the new rules applied in your 2018 paycheck.


For your 2017 taxes, much is the same as it has been.  So, stay focused for now on the 2017 rules to file your taxes.  And then plan appropriately for 2018 to make next year easier and perhaps fulfill some of those other financial goals for your future as well.    

To stay grounded in 2017 — while preparing for success in 2018 — let’s compare the old and new rules. 


Tax Rates and Deductions

As we file our taxes, most of us share the same goal: Reduce the amount of income we’re taxed upon to lower the amount we owe. There are two main methods, which are 1) to take the standard deduction, or 2) to itemize our deductions. Most Americans utilize the standard deduction1.  

  • The new rule: Starting in 2018, the TCJA nearly doubles the standard deduction amount you deduct from your income subject to taxation, and many experts believe it will increase the number of Americans using the standard deduction in the future.
  • Info for this year’s filing: While that may be good news for 2018, there was no change made to the 2017 amount. Be sure to take a close look at your itemized deductions to see if the total may outnumber your standard deduction to make the best choice for you this April.

Itemized Deductions

Much attention has been focused on the tax law changes to itemized deductions like state and local taxes (SALT), home mortgage interest deductions, medical expenses, and casualty or theft losses.  Take note of these points affecting many Americans.  



  • The new rule: In 2018, you may be limited to an itemized deduction of up to $10,000 ($5,000 for married filing separately or single).
  • Info for this year’s filing: Utilize the amount incurred the same way you did in 2016.

Mortgage Interest Deduction

  • The new rule: The TCJA limits mortgage interest deductions
  • Info for this year’s filing: You can still deduct interest paid in 2017 on mortgage debt, up to $1,000,000 (on mortgages started prior to Dec 16, 2017).

Medical Expenses

  • The new rule: Prior to the TCJA, if you incurred unreimbursed medical expenses above 10% of your Adjusted Gross Income (AGI), you could use that amount as an itemized deduction. The TCJA changed the threshold from 10% to 7.5% for tax years 2017 and 2018.  
  • Info for this year’s filing: If you unfortunately incurred these expenses in 2017, you may be able to use more of them as deductions for your 2017 tax return filing to lower your tax liability.

*Note that the Affordable Care Act personal mandate will be repealed in 2019, removing the penalty for not having qualified health insurance. That change does not affect the mandate for 2017 tax filings. And the penalty could be as much as $2,085 per person or the premium for the national average cost of a Bronze plan – whichever is higher.   


Casualty and Theft Losses

  • The new rule: The TCJA will disallow taking a deduction for these types of expenses unless they were incurred in a federal disaster area.
  • Info for this year’s filing: You still can utilize these as a deduction if they were incurred in 2017.                                                            

Changes to tax law may cause a little apprehension at tax time.  However, filing your 2017 taxes will not be dramatically different than when you filed your 2016 taxes.  Awareness of the changes for 2018 helps you prepare for next year, and make the best financial decisions possible throughout this year.  But don’t stop with taxes.  Keep up the momentum and start planning today for your financial future.  Talk to USAA regarding your plans for the future and how we can help you make them a reality.  Taxes are a concern to be sure, but proper financial planning involves much more than taxes alone.  Talk to an expert at USAA regarding your retirement and other financial goals while money is top of mind at tax time. 


Financial planning can give each of your dollars a mission for your success in 2018 and beyond.  Take the time make your plan today.  Who knows?  Perhaps filing your taxes is the inspiration you need to create a brighter financial future.  And then the spring flowers will smell a little sweeter this year.

An updated article for the 2018 tax year would be beneficial.
