What began in 1999 as a small trading company in Seoul now spans trade, energy, mergers & acquisitions and AI development. With partners in nine countries and eleven cities, we help businesses plan and build their next stage.
Trade, energy, M&A and investment, and AI development — four different fields, connected by the same people and the same partners.
Since 1999 we have handled imports into Korea and third-country trade from bases in Asia and Europe, dealing in household goods and corporate supplies. From finding new buyers to advising major Korean companies, our strength is a network built in person, on the ground.
We work in LNG and crude oil. Using the partner network built through decades of trade, we connect supply with demand and look at trading and investment opportunities with our partners. It is also why our North American base is in Calgary, Alberta.
We run each deal in eight stages, from market research and target selection through due diligence, deal structuring and post-merger integration, working with legal and tax specialists in each country.
AI research and software development are part of our registered business, and we build our services in-house. Our first product is a self-check AI for Korean tax audits that gives a taxpayer a first read on their audit exposure in about two minutes.
See what we built →Long before the internet was widespread, our CEO travelled the world in person to build relationships. Those relationships are the network today — a legal partner in Italy, a European partner in Germany, trade partners in Japan, Vietnam and Thailand, and local legal and tax specialists in every region.

Alberta holds the world’s fourth-largest oil reserves, and produces 80% of Canada’s oil and 60% of its natural gas. Trans Mountain carries Alberta crude to the west coast, and Coastal GasLink carries Western Canadian gas to LNG Canada in Kitimat — a project in which Korea Gas Corporation is a partner. Together they open an export route to Asian markets. Its corporate tax rate is the lowest in Canada, and it has the highest number of engineers per capita in North America. That is why KCY PARTNERS, working in LNG and crude, bases its North American operations in Alberta.
Tools that let taxpayers check their own exposure to a Korean tax audit or a fund-source review before the tax office does. Concept, rule design and launch were all done in-house. Both services are live at the addresses below.
Two self-checks. Businesses review revenue structure, expense classification and sector risk. Individuals review the source of funds and gift-tax exposure after buying property, using the PCI method. Built around the items reviewed in tax audits and explanation requests, and updated whenever the tax code changes. An inheritance-tax calculator and an NTS notice reader run alongside.
A fund-source calculator that simulates the National Tax Service’s PCI (property–consumption–income) analysis from outside. It compares declared income against actual spending and asset growth to show the kind of gap that can draw the tax office’s attention. Used mainly by cash-heavy businesses and professionals.
There are plenty of tax calculators. A program that computes how the tax authority decides whom to audit is a different problem — because that formula is not published.
The National Tax Service’s PCI logic is not public. We gathered the items that come up again and again in real audits and explanation requests, and set them down as rules.
One wrong deduction figure or penalty rate and the whole result is wrong. Every amendment means re-tuning the thresholds.
No name, no phone number. Figures are computed on the user’s own device and never sent to a server. Accuracy and privacy had to hold at the same time.
“You are at risk” is useless on its own. The output has to be something a tax accountant can review and explain to the taxpayer.
Built with former National Tax Service tax accountants, who put the judgement used in real audit responses into rules. It is experience, not data, that has to be translated — and that takes the longest.
In tax, an error is a tax bill. We design conservatively and hand ambiguous cases to a human specialist.
Canada treats AI as national strategy, and one of its three national AI institutes is Amii in Edmonton, Alberta. In December 2024 the Government of Alberta published its AI Data Centre Strategy, setting out to become North America’s location of choice for large-scale AI compute on the strength of cheap natural-gas power, a cold climate and industrial land. Wonder Valley alone is a $70 billion build-out.
KCY PARTNERS works in energy and AI at the same time. Alberta is where those two meet, and that is why our North American base sits there. The capability proven on Korean tax data — designing judgement algorithms against an unpublished rule set — carries over to AI for other regulated and administrative fields.

In 1999, CEO KangChan Yoon started out in business by founding a trading company in Seoul. Working from Korea with bases in China, Italy, Spain, Germany and India, he built a global trade business, finding new buyers through imports into Korea and third-country trade.
This was before the internet was widespread. He travelled widely to meet partners he could trust in person, and earned a reputation for reliability advising major Korean companies on trade.
Built on partnerships and friendships formed over many years, KCY PARTNERS now advises on cross-border M&A and investment across Korea, China, the United States, Canada, Italy and Germany. Working with legal and tax specialists in each country, it handles the legal and tax side of a deal quickly and accurately.
More recently he has carried that experience into technology and content. He built a self-check AI for Korean tax audits in-house; he talks through real tax-audit practice on his YouTube channel FunFunTax; and he set down the judgement earned in the field in his book “Tax Consulting Methods of the National Tax Service”.
KCY PARTNERS brings that mix of trade experience, deal work and a creative eye to every client, with one aim: to grow the value of what the client already has.
With former National Tax Service tax accountants, the channel covers what to prepare — and how — once a tax audit notice arrives.
