The beginning of the year always brings about change. Some are changes you may make by choice, like deciding to quit smoking or be more active. And others are changes that have been determined for you, like changes to your Medicare monthly premiums.
Whether or not you opted to change plans during the Medicare Open Enrollment Period, you may still see a change in your health insurance bills starting in January. That’s because 2019 Medicare Part B premiums are increasing across the board due to rising healthcare costs.
Exactly how much your premiums are increasing though, isn’t based on your current health or Medicare plan. Rather, your Medicare premiums are based on income with information from your tax returns from two years ago.
That’s right – your 2019 Medicare premiums are calculated by your 2017 tax returns.
So, exactly how are Medicare premiums determined? And, what does this mean for you and your Medicare premiums in 2019? Let’s take a closer look.
Medicare Premiums and the Government — Who Pays for What
A quick background on what Medicare premiums are may be helpful. Medicare is broken into two parts. Essentially:
- Medicare Part A – Hospitalizations and inpatient care
- Medicare Part B – Standard healthcare services
There are also options for supplemental coverage, notably:
- Medicare Supplement – Highly-regulated add-ons that pay your out-of-pocket Medicare costs
- Medicare Advantage – Private plans designed that combine and replace your Parts A, B, and D. Also known as Part C.
- Part D – Prescription drug coverage plans, introduced in 2006.
Generally, if you’re on Medicare, you aren’t charged a premium for Part A. However, you are charged monthly tax-deductible premiums for Part B and Part D, and can also be charged for Part C, depending on your particular plan’s coverage.
Most of Medicare Part B – about 75 percent – is funded through U.S. income tax revenue. But the remaining 25 percent of Medicare’s expenses are paid through your premium, which is determined by your income level. Medicare prices are quoted under the assumption you have an average income. If your income level exceeds the amount the government initially thought, you’ll be asked to pay more.
So, How Are the Medicare Premiums You Pay for Calculated?
These additional Medicare premiums are all calculated through something called IRMAA, which stands for Income-Related Monthly Adjustment Amount. It is an additional amount that you may have to pay along with your Medicare premium if your modified adjusted gross income (MAGI) is higher than a certain threshold.
Your MAGI is calculated by taking your adjusted gross income (AGI) plus any of the following that applies to you: untaxed foreign income, non-taxable Social Security benefits, and tax-exempt interest. For most people, your MAGI will be the same as your AGI.
How Much Are Medicare Premiums in 2019?
There are six income tiers for Medicare premiums in 2019. The standard Part B premium amount that most people are expected to pay will be $135.50. But, if your MAGI exceeds an income bracket — even by just $1 — you are moved to the next tier and will have to pay the higher premium.
Here’s a table that outlines the Premium increases based on income level and compares the 2019 costs to the costs of 2018.
|Individual Taxable Income (from two years ago)||Joint Taxable Income (from two years ago)||2018 Monthly Part B IRMAA Premium||2019 Monthly Part B IRMAA Premium|
|$85,000 or less||$170,000 or less||$134.00||$135.50|
|$85,001 to $107,000||$170,001 to $214,000||$187.50||$189.60|
|$107,001 to $133,500||$214,001 to $267,000||$267.90||$270.90|
|Above $133,500 to $160,000||Above $267,000 to $320,000||$348.30||$352.20|
|Over $160,000 (for 2019: and less than $500,000)||Over $320,000 (for 2019: and less than $750,000)||$428.60||$433.40|
|$500,000 and above||$750,000 and above||n/a||$460.50|
Most people who have been on Medicare for several years will still pay less than the lowest tier rate of $135.50, though. These people are protected by the hold harmless rule.
What is the hold harmless rule? Basically, if you collect Social Security benefits and your Medicare Part B premium is deducted from those benefits each month, the hold harmless rule ensures that your Social Security checks won’t decline from one year to the next because of increases in Medicare Part B premiums.
However, the hold harmless provision does NOT protect you if you are new to Medicare or are in a high-income bracket.
What if Your Financial Situation Has Significantly Changed Since Filing Your Tax Return from Two Years Ago?
As mentioned earlier, this is all determined by the information from your tax returns from two years ago. If you’ve had a life-altering event that affects your income level since then, such as the death of a spouse or retirement, you can go to Social Security’s website to fill out the Medicare Income-Related Monthly Adjustment Amount – Life Changing Event form. You don’t have to pay an amount that no longer makes sense.
