AMT exemption amounts, Social Security wage base bumped up in 2017

November 4, 2016


Welcome to Part 7 of the ol’ blog’s series on 2017 inflation adjustments.
You can find links to all 2017 inflation posts in the series’ first item: 
Income Tax Brackets and Rates.
Today we look at changes to the Alternative Minimum Tax exemption amounts,
as well as the previously announced increase in the Social Security wage base.
Note: The 2017 figures apply to 2017 returns that are due in 2018.
For comparison purposes, you’ll also find 2016 amounts to be used
in filing 2016 returns due next April.

The AMT, or Alternative Minimum Tax, forces some taxpayers to do extra work to pay more taxes. That’s why some folks say the AMT is essentially an ATM for the Internal Revenue Service.

The Internal Revenue Service’s focus at tax time is how much we made. It is, after all, called an income tax.

But some other income issues also are important at tax time and are affected by inflation.

Limiting Social Security taxes: Let’s start with the Social Security wage base. This is the amount of money that is subject to the tax that goes to support, you got it, Social Security.

Technically, the wage base isn’t indexed for inflation. Rather, the Social Security Administration uses a specific formula to set the maximum taxable earnings level when a cost-of-living adjustment is effective so that Social Security benefits can keep pace with, wait for it, inflation.

For 2016, the wage base is $118,500. 

After several years of stagnation, it will take a dramatic jump in 2017 to $127,200.

Those income levels are the maximum amount from which the 6.2 percent Social Security tax is collected. 

With the increase next year, that means the maximum amount of Social Security tax you could pay in 2017 goes to $7,886.40. That’s an increase of $539.40 over the $7,347 tax max in 2016.

Employers match their employees’ tax amounts, meaning the total Social Security tax is 12.4 percent. In dollars that comes to a Social Security tax maximum of $15,772.80 next year, up from the 2016 tax max of $14,694.

And once you earn more than the wage base, your boss will stop collecting the 6.2 percent Social Security tax from your pay.

No Medicare max: A quick note on the other part of the payroll tax, the Medicare portion of FICA, or the Federal Insurance Contributions Act.

This is an additional 1.45 percent from your pay, also matched by your employer. But unlike the Social Security tax, there is no  limit on the amount of your earnings subject to the Medicare tax.

Regardless of how much you earn, you and your employer will each keep paying that 1.45 percent tax.

One more payroll tax note. As part of the Affordable Care Act, aka Obamacare, there’s also a 0.9 percent additional Medicare tax on employees who earn more than $200,000 as single taxpayers or $250,000 if married filing jointly. This Medicare surtax is not matched by employers, but is paid only by the affected workers.

The bottom line is that all of us pay FICA taxes on some of our income. Most of us pay FICA on all of our income. And a few folks will pay more Medicare taxes on more of their income.

So keep an eye on your earnings. While it’s never fun to pay more taxes, at least if you do, it means that you’re doing pretty well pay wise.

AMT’s “rich” history: But wait. There’s more. And by more, I mean more of a chance that the IRS could snag a bit more of your earnings thanks to a special income tax.

The Alternative Minimum Tax, or AMT, is a parallel income tax that requires many taxpayers to compute their tax bills twice. First, they use the standard rules to fill out their 1040s. Then they use the AMT guidelines. And they pay the higher amount of those two calculations.

The idea for the AMT was born in 1969 in reaction to a few rich taxpayers — and by few, I mean a few: only 155 taxpayers — who back then avoided paying any tax. As originally enacted, the income levels at which the AMT kicked in were not indexed for inflation.

Today’s AMT we know (and yes, hate) has two rates, 26 percent and 28 percent, that apply to earnings after you add back some tax breaks you can claim under regular tax filing. Among the tax breaks disallowed under AMT are the state and local tax deduction and dependent exemptions.

Avoiding AMT tax trouble: Will you have to do the extra AMT tax math? The first indicator is your earnings. If you make less than the AMT annual exemption amount, you’re OK.

Thanks to the 2013 enactment of the American Taxpayer Relief Act, those AMT amounts are now indexed for inflation.   

Those amounts for 2016 are:

  • $53,000 for single and head of household taxpayers,
  • $83,800 for married couples filing joint returns/surviving spouses, and
  • $41,900 for married couples filing separately.

Inflation adjustments for the 2017 tax year bump up the AMT exemption amounts to:

  • $54,300 for single and head of household taxpayers,
  • $84,500 for married couples filing joint returns/surviving spouses, and
  • $42,250 for married couples filing separately.

Form 1040 and 1040A instructions have a worksheet you can use to see if you owe AMT. Yeah right.

OK, then try the IRS’ AMT assistant. This online tool basically takes the worksheet electronic. The IRS hasn’t updated it yet to reflect the 2016 data, but now that the 2015 filing season is totally over, the agency should get around to tweaking its website for the current tax year.

And, of course, if you use tax software like most of us do, it should tip you off if you might face the AMT.

Here’s hoping that the inflation adjusted exemption amounts will keep you out of the AMT for both 2016 and 2017.

Tax Season 2026 Continues!

We made it. Tax Day 2025 is finally over. For most of us. When the filing season started on Jan. 26, millions who were expecting refunds filed immediately. Most of us got our returns to the Internal Revenue Service by April 15. But plenty of taxpayers also got extensions. They are looking at an Oct. 15 filing deadline.

Those procrastinating filers aren’t a problem. In fact, the IRS appreciates taxpayers who take time to fill out their 1040 forms correctly. It also is grateful that tax submissions are spread out a bit, especially now that the IRS is a leaner agency. Processing returns is easier when they arrive throughout the year instead of in massive bunches.

But enough about Uncle Sam’s tax collection issues. The focus now is on all y’all who filed for extensions, giving you another six months to complete your return. Since your new mid-October due date will be here before you know it, let’s get started now on meeting it.

The ol’ blog is here to help you finish up your extended Form 1040. You can start with January’s tax tips page, which has links to the rest of the year’s tips by-month collections. You also can peruse various tax categories for more tailored advice by clicking on the More Tax Posts drop-down menu at the top of this (and every) page.

And to make sure you don’t miss your new filing deadline, the count-down clock below will let you know just how much time you to file by Oct. 15. At the latest.e. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
