Received a Marketplace Notice About Tax Reconciliation?

You’re not alone.

Every year, we hear from people who receive a Marketplace letter mentioning “tax reconciliation” and have no idea what it means.

The term sounds complicated, but the concept is actually fairly simple.


If you received financial assistance through the Health Insurance Marketplace, the government wants to make sure you received the correct amount of assistance based on your actual income.

That’s tax reconciliation.

Let’s break it down.


What Is Tax Reconciliation?

Tax reconciliation is the process of comparing:

  • The health insurance subsidy you received during the year, and
  • The subsidy you were actually eligible to receive based on your final income.

When you apply for Marketplace coverage, you estimate your income for the upcoming year.

Because life doesn’t always go exactly as planned, your actual income may end up being different.

Tax reconciliation allows the IRS to determine whether:

  • You received the correct amount of subsidy
  • You received too much subsidy
  • You received too little subsidy


Why Does Tax Reconciliation Matter?

Marketplace subsidies are not grants.

They are advance payments of a tax credit.

The government pays part of your health insurance premium throughout the year based on the information you provide.

When tax season arrives, the IRS verifies whether the subsidy amount was accurate.

This process helps ensure that financial assistance is distributed fairly.


How Does Tax Reconciliation Work?

Let’s look at a simple example.

Imagine you estimated your household income would be $45,000.

Based on that estimate, you qualified for a subsidy that reduced your monthly premium.

At the end of the year:


Scenario 1: Income Was Higher Than Expected

Your actual income ended up being $60,000.

Because your income was higher, you may not have qualified for as much financial assistance as you received.

As a result, you may need to repay a portion of the subsidy.


Scenario 2: Income Was Lower Than Expected

Your actual income ended up being $35,000.

Because your income was lower, you may have qualified for additional assistance.

In this case, you may receive additional tax benefits when filing your return.


What Forms Are Required?

Most Marketplace enrollees receive:

Form 1095-A

This form comes from the Marketplace and shows:

  • Coverage information
  • Premium amounts
  • Subsidies received during the year

This form is extremely important.

Do not throw it away.


Form 8962

This IRS form is used to complete the reconciliation process.

The information from Form 1095-A is used to calculate whether the subsidy received matches the subsidy eligibility.


Common Reasons Reconciliation Problems Occur

Income Changes Were Never Reported

Examples include:

  • New job
  • Pay raise
  • Retirement
  • Increased self-employment income
  • Investment income
  • Rental income

Household Changes

Examples include:

  • Marriage
  • Divorce
  • Birth of a child
  • Dependents added or removed


Missing Tax Filings

If tax returns are not filed, subsidy eligibility can eventually be affected.


Incorrect Marketplace Information

Errors in income estimates or household information can lead to reconciliation issues.


What Happens If I Don’t Complete Tax Reconciliation?

This is where many people run into trouble.

If you received Marketplace subsidies and fail to complete the required tax filing and reconciliation process, you may eventually lose eligibility for future subsidies.

In other words, your financial assistance could be suspended or terminated until the issue is resolved.


We’ve seen situations where people believed they had filed everything correctly, only to discover that a required Marketplace form was missing.


Important: Check Every Year You Received a Subsidy

One of the biggest misconceptions is that the Marketplace only reviews the most recent year.

In reality, if you received subsidies over multiple years, you should ensure that:

  • Tax returns were filed for each year
  • Required Marketplace forms were included
  • Tax reconciliation requirements were satisfied

If you’re unsure, it may be worth reviewing prior filings with a tax professional.


Frequently Asked Questions


Is tax reconciliation the same as filing taxes?

Not exactly.

Tax reconciliation is part of the tax filing process for individuals who received Marketplace subsidies.


What happens if I lose my Form 1095-A?

You can typically access a copy through your Marketplace account or request assistance from the Marketplace.


Will I always have to repay money?

No.

Some individuals owe money back, while others receive additional tax credits.


What if my income changed during the year?

Income changes are one of the most common reasons reconciliation adjustments occur.


Can I lose my subsidy if I don’t reconcile?

Yes. Failure to complete required tax reconciliation may affect future subsidy eligibility.


Should I contact the Marketplace or my tax professional?

Often both can be helpful. The Marketplace can explain coverage information, while your tax professional can assist with filing requirements.


How to Avoid Tax Reconciliation Problems

A few simple habits can help:

  • Report income changes promptly.
  • Open and review Marketplace notices.
  • Keep copies of all tax documents.
  • Save Form 1095-A each year.
  • Review your Marketplace application annually.
  • Work with a trusted tax professional when needed.


The Bottom Line

Tax reconciliation is simply the process of making sure the health insurance subsidy you received matches the subsidy you were actually eligible for.

While the process can sound intimidating, understanding how it works can help you avoid surprises and protect your future subsidy eligibility.
