Estimating Your 2027 Income for Marketplace Savings

If you're shopping for a 2027 ACA Marketplace plan, one question can feel strange: how much money do you expect to make next year? Most of us know what we earned last year, not what we'll earn in a year that hasn't started yet.

That guess matters. On the Marketplace, your expected household income helps decide whether you qualify for savings that can lower your monthly premium, and sometimes your out-of-pocket costs. A careful estimate now can help you avoid surprises later.

This guide explains why the estimate matters, how to build a realistic one, and what to do if your income changes during the year.

Why Your Income Estimate Matters So Much

Marketplace savings are usually based on your projected income for the coverage year, not your past income. When you apply, you give your best estimate for 2027, and the Marketplace uses it to figure out what help you may qualify for.

Many people choose to have that help paid ahead of time, straight to the insurance company, so their monthly bill is lower. Because it's paid in advance based on a guess, it gets checked against your actual income later, usually when you file taxes for that year.

Here's the basic idea:

  • If your real income ends up close to your estimate, things usually line up smoothly.
  • If you earned more than you estimated, you may have received more help than you qualified for, and you might have to pay some of it back.
  • If you earned less than you estimated, you may have qualified for more help than you got, and that could work in your favor.

How this works for your household depends on rules that can change by year, so it's smart to talk with a tax professional about the tax side. A licensed advisor can help you with the coverage side and walk you through how the estimate affects your plan options.

Start With What You Already Know

The easiest way to build an estimate is to start with real numbers and then adjust. Before you sit down, gather a few things:

  • Recent pay stubs for everyone in your household who earns income
  • Last year's tax return, if you have it handy
  • Records of other income, like freelance work, side jobs, or rental income
  • Any letters about upcoming raises, new jobs, or changes in hours

Then ask yourself some simple questions. Will anyone in your home start or stop a job next year? Is a raise or a cut in hours coming? Is someone retiring, going back to school, or starting a business? Is your household size changing, like a new baby or a child moving out?

Each of these can shift your estimate. Write down your best guess for each person, then add them together.

One important note: the Marketplace uses its own definition of income, and it isn't always the same as the number on your paycheck. Certain types of income count and certain deductions may lower it. The application asks questions to help sort this out, and an advisor or tax professional can help if you're unsure what to include.

Tips for Steady, Changing, and Self-Employed Income

Not everyone's income looks the same. Here's how to approach a few common situations.

If you have a steady paycheck, your estimate may be simple. Look at what you earn now, think about any expected raise, and project it across the year.

If your hours change a lot, like in seasonal work, restaurants, or retail, look at a full year of earnings if you can. Busy months and slow months tend to balance out. Using only your best month or worst month can throw your estimate off.

If you're self-employed or work as a 1099 contractor, estimating takes a little more care. Your business income may go up and down, and business expenses can affect the income figure that counts. A few ideas can help:

  1. Look back at your business income over the past year or two to spot patterns.
  2. Think about contracts or clients you expect to gain or lose.
  3. Keep track of business expenses, since they can affect your net income.
  4. Talk with a tax professional about how your business income is counted.

If you truly can't tell, aim for a realistic middle-of-the-road number instead of a hopeful low one. A thoughtful estimate is better than a lucky guess.

When Life Changes, Update Your Application

Your estimate isn't locked in forever. Life happens, and the Marketplace expects that. If your income or household changes during 2027, you can usually update your application.

It's a good idea to report changes like these:

  • Starting a new job or losing a job
  • A big raise, bonus, or drop in hours
  • Landing a large new client or losing one if you're self-employed
  • Getting married or divorced
  • Having or adopting a baby
  • Someone joining or leaving your household

Updating your information helps keep your savings in line with your real situation throughout the year. That can lower the chance of a big surprise when you file taxes. Some changes may also open a special enrollment period, which could let you switch plans. The rules and time limits vary, so check with an advisor as soon as something changes.

A simple habit helps: every few months, look at what you've earned so far and ask whether you're still on track with your estimate. If you're way ahead or behind, it may be time to update.

Common Mistakes to Avoid

A few slip-ups come up again and again during open enrollment. Watch out for these:

  • Copying last year's number without thinking about what will change next year
  • Leaving out a spouse's income or side income from gig or freelance work
  • Guessing low just to get a lower monthly premium right now
  • Forgetting to update the application after a job change
  • Letting coverage auto-renew without checking whether your income estimate still makes sense

That auto-renew point is worth repeating. Even if you love your current plan, open enrollment is a good time to review your income information. Your situation, your plan options, and the savings rules can all change from year to year.

How a Licensed Advisor Can Help

Estimating income can feel like a lot, especially if you're also comparing plans, checking doctors, and thinking about prescriptions. You don't have to figure it out alone.

A licensed advisor can help you understand how your estimate may affect your Marketplace options, compare plans side by side, and look at whether a Marketplace plan or a private PPO plan might be a better fit for your needs. For questions about taxes, an advisor can point you toward getting help from a tax professional.

Open enrollment dates and rules vary by state and year, so it's best to start early and give yourself time to make a careful choice.
