Tax Credits Worth Knowing: EITC, the Child Tax Credit, and Free Filing

Tax credits are one of the most valuable, and most overlooked, tools for working households. Unlike a deduction, which lowers the income you’re taxed on, a credit reduces your tax bill directly. Some credits can even increase your refund beyond what you paid in. Yet every year, many people who could claim these credits don’t, often because they don’t file at all or don’t realize they may qualify.

This guide explains two of the biggest credits for families and workers, plus the free ways to file so more of your refund stays with you. PennyGuide isn’t a tax preparer or the IRS, and we can’t tell you whether you qualify. Think of this as a friendly map, then confirm the details with the IRS or a certified volunteer.

Credits vs. deductions in plain English

Here’s the simplest way to picture the difference:

A deduction lowers the amount of income that gets taxed.
A nonrefundable credit lowers your tax bill, but generally not below zero.
A refundable credit can lower your tax bill and, if the credit is bigger than what you owe, may come back to you as part of your refund.

That last category is why credits like the EITC can matter so much for households with modest incomes.

The Earned Income Tax Credit (EITC)

The IRS describes the EITC as a tax break for low- to moderate-income workers and families. It may reduce what you owe and may increase your refund.

Who it’s for

To qualify, you generally need earned income (from a job or self-employment) within the IRS income limits. The credit amount depends on factors such as:

Your income and filing status
Whether you have qualifying children or other dependents
Whether you have a disability
Other IRS rules (military members and clergy have special rules worth reviewing)

You may qualify even without children, though the rules and amounts differ. Because the income limits and credit amounts change every year, the most reliable move is to use the IRS EITC Assistant, a free online tool on IRS.gov that walks you through the questions.

A note on refund timing

If you claim the EITC, the IRS says it must hold your refund until mid-February. If you’re counting on that money, plan your monthly budget around a later arrival rather than an early-January one.

The Child Tax Credit

The Child Tax Credit helps families with qualifying children. According to the IRS, the key rules include:

The child must be under 17 at the end of the tax year.
You (or your spouse, if filing jointly) and each qualifying child generally need a Social Security number valid for employment, issued by the return’s due date.
The child must meet relationship, support, residency, dependency, and citizenship tests. For example, the child generally must have lived with you for more than half the year.

The refundable part

Part of the Child Tax Credit is refundable through what the IRS calls the Additional Child Tax Credit (ACTC). To claim it, you need at least a minimum amount of earned income. That means some families who owe little or no tax may still receive part of the credit as a refund.

The Credit for Other Dependents

If someone in your household doesn’t qualify for the Child Tax Credit, such as an older child or a parent you support, you may be able to claim the nonrefundable Credit for Other Dependents instead.

Families claim these credits on Form 1040 with Schedule 8812. Amounts and income phase-outs can change with new tax law, so always check the current figures on the IRS Child Tax Credit page.

Free ways to file

Paying to file can eat into a refund. The IRS supports several free options:

IRS Free File

IRS Free File is a partnership between the IRS and tax software companies. If your adjusted gross income is at or below the yearly limit, you can use guided software to prepare and e-file your federal return for free. A few things to know:

Start at IRS.gov. You must begin from the IRS Free File page, not a company’s own site, to get the free offer.
Each partner sets its own rules, and some may charge for state returns.
Free File Fillable Forms is available at any income level. It’s more hands-on (electronic versions of paper forms with limited calculations) and doesn’t include state filing.

VITA and TCE

Volunteer Income Tax Assistance (VITA) offers free basic tax preparation from IRS-certified volunteers, generally focused on people who may qualify for the EITC, people with disabilities, and taxpayers with limited English. Tax Counseling for the Elderly (TCE) focuses on taxpayers 60 and older, especially with pension and retirement questions.

You can find a site with the VITA Locator Tool on IRS.gov or by calling 800-906-9887. Services vary by site, so check before you go and bring the documents on the IRS checklist.

A worked example

For example, imagine a single parent with one child under 17 who earned wages from a part-time job. Last year they skipped filing because they assumed their income was too low to matter.

This year they:

Use the IRS EITC Assistant and learn they may qualify for the EITC.
Read the Child Tax Credit rules and confirm their child meets the age and residency tests.
Visit a nearby VITA site and have a certified volunteer prepare their return for free.

In this illustration, filing could lead to a refund that might otherwise have been left unclaimed. Every household is different, so the outcome depends on the IRS rules and their own situation. You can also generally claim a refund for a prior year if you file within the IRS time limit, which is worth asking a volunteer about.

Getting organized makes it easier

Credits require documentation: W-2s, 1099s, Social Security cards, and records showing where your children lived. A simple system helps. Our tax season organization guide walks through a folder setup that takes about an hour.

If a refund arrives, consider giving part of it a job before it disappears. Even a small transfer into savings can help. The savings goal tool and our guide to setting savings goals you can actually reach can help you decide how much.

Protect yourself at tax time

Tax season attracts scammers. Keep these in mind:

Be wary of unexpected texts, emails, or social media messages claiming to be from the IRS. Go to IRS.gov directly instead of clicking links.
Never pay a stranger who promises a bigger refund for a fee based on the refund size.
Be cautious of anyone who won’t sign the return they prepare.
Free help is available through IRS Free File, VITA, and TCE, so there’s no need to pay someone you don’t trust.

Your next small step

Go to IRS.gov and run the EITC Assistant, even if you’re not sure you qualify. It takes a few minutes and will tell you what documents to gather for tax season.
