Use this quick health insurance tax credit guide to help you understand the process, or just use one of our ObamaCare subsidy calculators for a quick estimate on marketplace cost assistance.  Cost assistance for individuals, families, and businesses is calculated automatically when you fill out an application on the Health Insurance Marketplace, however it’s good to understand how the process works yourself.

Use the tools below to find out if you qualify for Tax Credits for lower Premiums, Cost Sharing subsidies for reduced out-of-pocket costs, or Medicaid on your state’s Health Insurance Marketplace.

Some Quick Tips on ObamaCare’s Cost Assistance Subsidies

Before you start Shopping For Health Insurance, make sure you understand the following quick tips about cost assistance under the Affordable Care Act.

•  You’ll need to understand the Federal Poverty Guidelines, commonly called Federal Poverty Level (FPL), to know what type of cost assistance you are eligible for in 2015. You can find the current Federal Poverty Guidelines here.

•  Cost assistance is based on your projected income for 2015 and then adjusted for your actual income at the end of the year.

• Cost assistance is only available through the Health Insurance Marketplace.

• The marketplace is only open during open enrollment!

•  All  non-exempt Americans can use the marketplace to see if they qualify for cost assistance.  However there are a few exceptions: If you are eligible for Medicare, you won’t use the marketplace.  If you have access to qualifying employer based insurance, you can use the marketplace but can’t get cost assistance.  If your state didn’t expand Medicaid, there may be other eligibly requirements for Medicaid beyond income.

• Cost assistance includes: Advanced Premium Tax Credits for those making between 100% and 400% FPL, Cost Sharing Reduction subsidies for those making between 100%-250% FPL, and Medicaid for those making less than 138% FPL in states that expanded Medicaid.

• As a rule of thumb if you make less than $46,680 as an individual or $95,400 you make less than 400% FPL and will qualify for some sort of assistance.

•  Cost Sharing Reduction subsidies are only Offered On Silver Plans.

•  Tax Credits cap the maximum premium you can pay.  The amount is between 2%-9.5% of your MAGI for the cheapest Silver plan.

• Children can also get Medicaid cost assistance through CHIP.

•  Tax credits can be paid in advance to lower your premium upfront or can be deducted from your Federal income taxes at the end of the year.

• If your income changes you should report it to or your states exchange so they can adjust your cost assistance levels.  This will avoid you paying too much or owing money on your year end taxes.

• If you have a plan from the previous year, it’s good practice to verify your plan and information before the next year starts.   See more about verifying information and switching plans.

• For small business owners who are looking for information on small business tax credits, please see our page on using the Small Business Health Options Program (SHOP).

•  Check out our ObamaCare subsidies page for more information on tax credits, out-of-pocket subsidies, and Medicaid and CHIP.

Below is some helpful information from a free guide offered by

Individual Health Insurance Tax Credits

The amount of your health insurance tax credit is based on the premium for the second lowest cost “silver plan” in your state’s individual Health Insurance Marketplace.

The amount of the tax credit varies with income such that the premium you would have to pay for the second lowest cost silver plan is capped as a percentage of income (adjusted for household size), as follows:

How to Calculate Your Health Insurance Tax Credit

Step 1- Calculate Your Modified Adjusted Gross Income (MAGI)

Step 2 – Use Your MAGI and Household Size to Determine if You are Eligible for a Tax credit

Step 1 – Calculate Your Modified Adjusted Gross Income (MAGI)

How to Calculate Your Health Insurance Tax Credit

Step 1- Calculate Your Modified Adjusted Gross Income (MAGI)

Step 2 – Use Your MAGI and Household Size to Determine if You are Eligible for a Tax credit

Step 1 – Calculate Your Modified Adjusted Gross Income (MAGI)

Why Does MAGI Matter?

Modified Adjusted Gross Income is a measure used by the IRS to determine if a taxpayer is eligible to use certain deductions, credits, or retirement plans. “Modified Adjusted Gross Income” (not “Adjusted Gross Income”) will be used in determining eligibility for your health insurance tax credits. The IRS phases out the tax credit as your income increases. By adding MAGI factors back to your AGI, the IRS determines how much you really earned. Beginning in 2014, your MAGI determines whether you will be eligible for premium tax credits on the new Health Insurance Marketplaces

What is Adjusted Gross Income?

Generally, your Adjusted Gross Income (AGI) is your household’s income less various adjustments. Adjusted Gross Income is calculated before the itemized or standard deductions, exemptions and credits are taken into account.

What is Modified Adjusted Gross Income?

Generally, your Modified Adjusted Gross Income (MAGI) is the total of your house hold’s Adjusted Gross Income and any tax-exempt interest income you may have (these are the amounts on lines 37 and 8b of IRS from 1040).

How to Calculate Your Gross Income (GI)

Your gross income is the money you earned through wages, interests, dividends, rental and royalty income, capital gains, business income, farm income, unemployment and alimony. This is the basis for your AGI calculation.

Gross income includes salary, interest earned, income from investments and basically any income you made through business, trade or investments.

How to Calculate Your Adjusted Gross Income (AGI)

Once you have gross income, you “adjust” it to calculate your AGI. You make adjustments by subtracting qualified deductions from your gross income.

Adjustments can include items like some contributions to IRAs, moving expenses, alimony paid, self-employment taxes, and student loan interest.

There are many free AGI calculators available online.

How to Calculate Your Modified Adjusted Gross Income (MAGI)

Once you have adjusted gross income, you “modify” it to calculate your MAGI.  Specifically, Modified Adjusted Gross Income (MAGI) is calculated by adding back certain items to your Adjusted Gross Income including:

• Deductions for IRA contributions.

• Deductions for student loan interest or tuition.

• Excluded foreign income.

• Interest from EE (employee) savings bonds used to pay higher education expenses.

• Employer-paid adoption expenses.

• For most people, MAGI is the same as AGI.

Step 2 – Use Your MAGI and Household Size to Determine if You are Eligible for a Tax Credit

You can use the following table to figure out if you would be eligible for a tax credit based on your 2014 income.  Please see our Federal Poverty Guideline page for more details.

If you are eligible for a tax credit, an online calculator will help you estimate your actual tax credit. This estimate will give you an idea of how much health insurance will cost you and your family in 2014. Insurance rates for 2014 have not yet been finalized so keep in mind that, once you are ready to purchase a health plan, the actual cost will likely change from this estimate.
