Income Amount Certificate Korea Visa: The 소득금액증명원 Explained

The income component of the F-2-7 points system carries more weight than any other single category — up to 60 points out of 170. Every point in this category must be proven by one specific government document: the 소득금액증명원 (Certificate of Income Amount), issued by the National Tax Service. Getting this document wrong — or misreading it — is the single most common reason applicants score far fewer income points than they expected.

What Is the 소득금액증명원?

The 소득금액증명원 (Income Amount Certificate) is an official NTS document that states your total taxable income for a given tax year. It is not a pay stub. It is not a bank statement. It is not your employer's certificate of employment. It is the NTS's own calculation of how much taxable income you earned, based on what was reported to them through the tax filing system.

For F-2-7 purposes, immigration officers use the most recent year's certificate. If you are applying in 2026, you typically need the 2025 tax year certificate (income earned in 2025, reported and filed by the end of May 2026).

How to Get It

1. Log in to the National Tax Service's Hometax portal at hometax.go.kr
2. Navigate to: 민원증명 → 소득확인증명서 (or search for 소득금액증명원)
3. Select the tax year you need
4. Issue the certificate — you can download it as a PDF or print it at any tax office

You can also obtain it in person at any regional NTS office or at a government 24 kiosk (민원24). The document is free to issue.

One important note: the certificate is only available once your tax filing for that year has been processed. If you are applying early in the year and your most recent tax filing is still pending, you may need to use the previous year's certificate or wait for processing to complete.

What the Document Shows — and What It Doesn't

The figure that appears on the certificate is your taxable income after the NTS's own calculations. For salaried employees, this is close to the gross salary minus the standard employment income deduction (근로소득공제). For most mid-range salaries, the deduction reduces gross salary by roughly 15–30%.

This means an employee with a ₩52 million gross salary might show approximately ₩40–44 million on the income amount certificate. Using the F-2-7 income table, ₩40–50 million earns 40 points — not the 45 points that ₩50–60 million gross would suggest.

For freelancers and self-employed operators, the reduction is far more severe. The NTS applies an expense deduction ratio based on your business type that can reduce your reported income by 60% or more. A consultant billing ₩80 million may show ₩32 million in taxable income on the certificate, yielding only 30 points rather than the 56 points their gross receipts would otherwise earn.

The income table used for F-2-7 scoring is based on the GNI per capita (₩49,955,000 for 2025 applications). The brackets are fixed regardless of whether your income looks high or low by international standards.

Common Mistakes

Using the wrong document. Some applicants submit a 근로소득 원천징수영수증 (withholding tax receipt) or a 재직증명서 (employment certificate) instead of the 소득금액증명원. Immigration officers will only accept the NTS-issued certificate. Submitting anything else means your income points cannot be verified and will be scored at zero.

Wrong tax year. The certificate must match the tax year specified in the application. Using last year's certificate when this year's is available — or vice versa — can create a mismatch that delays processing.

Untaxed income. Cash payments, informal allowances, and income from unofficial sources do not appear on the certificate. If your employer pays part of your compensation off the books, that portion is invisible to immigration. The only way to count income is to have it reported and taxed through the proper channels.

Multiple income sources. If you have both employment income and freelance income in the same year, the certificate should reflect both. Make sure your combined income is filed under a single NIN (납세자번호) so the total appears on one document.

What Income Level Do You Actually Need?

The F-2-7 income points table rewards high earners significantly. The jump from ₩30–40 million (30 points) to ₩40–50 million (40 points) is worth 10 points — equivalent to two full years of volunteering or passing TOPIK Level 4 instead of Level 3.

Most professionals targeting the 80-point threshold with a bachelor's degree and mid-range Korean language (TOPIK 3 or KIIP Level 3) need at least ₩40–50 million in taxable income to make the numbers work. Those with weaker language scores or lower academic qualifications need higher income to compensate.

If your income is borderline, getting your employer to include housing allowances and performance bonuses in your formal taxable compensation — rather than paying them informally — can push you into the next bracket.

Timing Your Application Around the Certificate

Because the certificate reflects the prior tax year, the optimal application window is often after the current year's tax returns have been filed and processed (typically July onward each year). Applying before your highest-earning year's certificate is available means using a lower-income year's figure — potentially costing you 10–20 points.

If your income has grown substantially, delay your application until the stronger year's certificate is available. If you are already above 80 points with the current certificate, apply now rather than waiting — your age category will only decrease over time.
