Trading CME overnight futures has become increasingly popular among Korean investors seeking exposure to global markets after local trading hours. While the opportunities for profit are attractive, it’s equally important to understand the practical aspects of how to trade these futures and how to handle the related tax reporting. In this article, we’ll walk through how CME overnight futures trading works, what investors should know about tax responsibilities, and where to find support if you’re new to cross-border investing.
How cme overnight futures trading works
CME 야간선물 (Chicago Mercantile Exchange overnight futures) allow investors to trade various global index futures—including the KOSPI 200—during US market hours. These products are especially useful for Korean investors who want to react to international market developments in real time, rather than waiting for the next morning’s open in Korea. Trading is typically done through a brokerage that supports global futures, and most Korean investors use domestic brokers that offer overseas futures access via platforms like HTS or MTS.
The trading hours usually follow the US market schedule, starting around 6 PM KST and continuing into the early morning. The most actively traded contracts include equity indices, commodities, and currency futures. While trading CME products, investors deal in foreign currency (mainly USD), and margin requirements, commissions, and leverage can differ significantly from Korean domestic futures.
What you need to know about tax reporting
Earnings from CME futures are considered overseas financial income for Korean residents and are subject to annual tax reporting. If your total overseas financial assets exceed KRW 500 million at any point in the year, you are also required to file a “Report of Overseas Financial Accounts” with the National Tax Service (NTS) of Korea.
For futures trading profits, capital gains must be declared through the global income tax return filed between May 1st and May 31st of the following year. Tax is typically assessed on net capital gains (profits minus losses), and depending on the amount, you may fall under a progressive tax rate. It’s essential to keep accurate transaction records, including contract details, trading dates, and exchange rates at the time of settlement, to ensure proper filing.
Note that CME itself does not withhold any taxes on behalf of foreign investors. The responsibility to report and pay taxes lies entirely with the individual trader under Korean tax law.
Tips for staying compliant and avoiding penalties
Many first-time investors in CME markets underestimate the importance of tax compliance. Missing the reporting window or failing to report foreign financial assets can result in substantial fines. Using brokerage statements and downloadable transaction histories can simplify the process of calculating gains and filing your taxes. Some investors also seek help from tax advisors who specialize in overseas investments or use tax software that supports global income reporting.
If you’re unsure about your obligations, consider contacting the National Tax Service or a licensed Korean tax accountant. Several brokerage firms also publish guides on overseas investment taxes, often available in both Korean and English.
Frequently asked questions
do i have to report taxes the same way for kospi overnight futures?
Yes, if you are trading KOSPI overnight futures through the CME (not the Korean Exchange), the same tax reporting rules apply as they are considered overseas financial products. You must report gains or losses in your global income tax return, and if your total overseas assets exceed KRW 500 million, you are also required to submit a Report of Overseas Financial Accounts. However, if you trade KOSPI futures through the Korean Exchange (KRX), they are taxed domestically under different rules.
do i have to report my cme futures trading even if i made a loss?
Yes. Even if you incurred losses, you’re required to report your overseas financial activity. Reporting losses properly can be helpful in offsetting future gains for tax purposes.
what is the tax rate on profits from cme futures trading?
Overseas futures profits are usually taxed as capital gains, subject to progressive tax rates depending on the amount. In many cases, this falls under the “global income” category and should be reported during the annual May tax return window.
how can i get a summary of my trades for tax reporting?
Most brokerages that support CME trading provide downloadable trade reports or year-end summaries. These typically include necessary information like profit and loss, trading dates, and transaction fees.
what happens if i don’t report overseas futures income?
Failure to report overseas income can result in penalties, back taxes, and in severe cases, audits or legal action by the National Tax Service. If your overseas assets exceed KRW 500 million and you fail to submit the financial account report, additional fines apply.
