The Ultimate Guide to the Earned Income Tax Credit (EITC): From Eligibility to Application

Every May, many workers and business owners turn their attention to a specific program: the 'Earned Income Tax Credit' (EITC). This is a representative tax support measure where the government provides direct cash assistance to households struggling with low earned income, aiming to boost work motivation and supplement actual income. Beyond simply providing funds, it has established itself as a crucial welfare system by encouraging self-reliance. However, because the income and asset requirements are complex, many people are often confused about whether they qualify. Today, we will take a detailed look at the EITC, focusing on practical information ranging from its core concept to eligibility and often-overlooked precautions.

1. What is the Earned Income Tax Credit?

The EITC is designed to encourage work and support actual income for households that have earned income but face economic difficulties due to low earnings. This is different from the Basic Livelihood Security Program. While the Basic Livelihood Security Program focuses on 'protection' to maintain a minimum standard of living, the EITC differs in that it provides benefits to those who are 'actively working.' Therefore, as a rule, those who are not working are excluded from eligibility.

The payment amount is calculated based on the total combined annual salary of the couple, depending on the household composition. The payment varies based on the household type (single, single-earner, dual-earner) and is designed to provide the most support when income is below a certain level. The National Tax Service (NTS) sends out notification letters to eligible individuals every year based on income data, but not receiving a letter does not necessarily mean you are ineligible, so it is important to check your requirements yourself. In practice, for daily workers or part-timers whose income is difficult to verify, the top priority is to check whether their statement of earnings has been properly submitted to the NTS.

2. Understanding Income Requirements by Household Type

The first hurdle in applying for the EITC is the 'income requirement.' The standard income is set differently depending on the household members. A single-person household must have a total annual combined income of less than 22 million KRW, a single-earner household less than 32 million KRW, and a dual-earner household less than 38 million KRW. 'Total income' here refers to the sum of earned income, business income, interest income, dividend income, pension income, and other income.

It is important to note that this is not just your monthly salary, but the annual combined amount calculated on a pre-tax basis. For dual-earner households, this means the spouse's income must be at least 3 million KRW; if this criterion is not met, it is classified as a single-earner household. If your income is close to the threshold, the fastest and most accurate way to check your exact income bracket is to use the 'Simple Calculator' provided on the NTS Hometax website. A practical tip is to log in to NTS Hometax and use the 'EITC Review Data Inquiry' menu to identify your total annual income in advance.

3. Asset Requirements: The Meaning of 240 Million KRW

Even if your income is below the threshold, you will be excluded if you do not meet the asset requirements. The total assets owned by all household members must be less than 240 million KRW. Assets here include housing, land, buildings, savings, deposits, stocks, memberships, and jeonse (lease) deposits. Since debt is not deducted from assets, you may be ineligible if your total asset value is high, even if you have significant loans.

In particular, for jeonse deposits, the deposit amount on the lease contract is counted as an asset, so caution is required. However, if the total asset value is between 170 million KRW and 240 million KRW, the payment amount is reduced by 50%. This reflects a policy intent to concentrate more benefits on households with fewer assets. As a precaution, since official real estate prices change every year, you should always be aware that even if you met the asset requirements last year, you might be disqualified this year due to an increase in the official price. You can indirectly estimate your asset value through sites like the 'Real Estate Official Price Notification' website.

4. Cases Excluded from Application

Even if you meet all conditions, there are exceptional situations where you cannot apply. The most representative case is not holding South Korean citizenship. However, exceptions are made if you are married to a South Korean citizen or have a dependent child who is a South Korean citizen. Also, if you are registered as a dependent child of another resident as of December 31st of the current year, you cannot apply yourself.

Additionally, professional business owners (lawyers, doctors, accountants, etc.) are fundamentally excluded from EITC eligibility regardless of their income scale. This is in line with the program's purpose of supporting low-income groups. If you are unsure whether you are eligible, it is best to verify through the NTS consultation center. Applying based on incorrect information may lead to being identified as an improper recipient, resulting in penalties. Especially when separating or merging households, you should verify in advance that your residential status on the resident registration matches the facts to avoid unnecessary administrative misunderstandings.

5. How to Apply: Using Hometax and ARS

Applying for the EITC has become very simple. The most recommended method is to use the NTS Hometax website or the mobile app (Sontax). If you have received a notification letter, you can complete the application with just a few clicks by entering the individual authentication number provided in the letter. Even if you did not receive a letter, you can apply by entering your income details directly on Hometax.

For those who find it difficult to use digital devices, a telephone application service (ARS) is also available. By calling the number provided in the notification letter and entering your resident registration number and individual authentication number, you can complete the application process without speaking to an agent. The application period is generally throughout the month of May, and it is advantageous to apply within the period, as late applications will result in a 10% reduction in the payment amount. A practical tip is to verify in advance that the address where you will receive the notification letter sent by the NTS in late April matches your current residence. If you do not receive the mail, the probability of missing the application period is high.

6. Payment Calculation and Timing

The payment amount is determined by a calculation table based on household composition and total salary. It is structured so that the payment is higher for lower incomes and decreases after a certain threshold. The final payment amount is determined after a review process and is usually paid within 3 months of application. If you apply in May, you will generally receive payment between the end of August and September.

Payments are deposited into the financial account under your name that you provided during the application. If you did not provide an account or if there is an error, you will have to receive a tax refund notice by mail and collect the cash at a post office, which is inconvenient. Therefore, it is important to provide your account number accurately. When deposited, it will appear under the name 'Earned Income Tax Credit' (근로장려금) on your bank statement. As a precaution, if your account is under seizure, you may not be able to receive the payment, so you should check your account status or inquire with the NTS about changing the payment method before applying.

7. Common Mistakes and Precautions

One of the mistakes many applicants make is 'omitting income.' If you do not report income earned from part-time jobs or freelance work to the NTS, it will not match the NTS data, leading to disqualification during the review or requiring a subsequent income tax amendment. It is recommended to check in advance whether your income is accurately reported to the NTS.

Also, if you enter incorrect contact information, you may not receive requests for supplementary documents or notifications. In particular, if there are changes in household members, they must be accurately reflected during the application. Since the EITC is a welfare program separate from tax refunds, you can receive it even if you have not paid taxes. Remember that it is a system for those who do not need to pay taxes because their income is low. As a point of comparison, if you are receiving other welfare benefits (such as livelihood benefits), the EITC payment may be deducted or affected, so it is wise to check with your welfare case worker about the possibility of overlapping benefits.

8. Disadvantages of False Applications

If you intentionally report lower income or conceal assets to receive the credit improperly, not only will the amount received be clawed back, but you will also be restricted from receiving it for 2 years. Furthermore, if you receive it through fraud or other improper means, you may be restricted from receiving it for 5 years. This is a matter that can lead to legal responsibility, not just the issue of returning the money.

The NTS conducts periodic post-verification of recipients. Since they thoroughly cross-check changes in income and assets, applying honestly is the safest approach. If you met the eligibility requirements at the time of application but your income increased afterward, it is better to check for changes in your eligibility yourself to prevent unnecessary administrative disputes. A checkpoint is that when you receive a post-verification notification letter from the NTS, do not ignore it; preparing supporting documents and responding immediately is the best way to minimize future disadvantages.

9. How to Get Additional Help

In addition to the EITC, there are various welfare programs for low-income groups. These include the Child Tax Credit, as well as housing support or energy vouchers implemented by local governments. When you apply for the EITC, the NTS system also checks your eligibility for the Child Tax Credit, so you can receive integrated benefits without a separate application process. Periodically check the various information provided by the government to ensure you do not fall into welfare blind spots.

Financial and tax-related information may be interpreted differently depending on individual circumstances. This article provides general information, and for specific tax consultations or legal judgments, we recommend using the official NTS consultation center (dial 126 without an area code) or seeking help from a tax professional. Accurate information verification is the surest way not to miss out on welfare benefits.

We hope this guide resolves your questions about the EITC and helps those in need receive the appropriate benefits. We hope you understand the purpose of the system and apply correctly to gain economic assistance.
