TSMC's U.S. factory will wait three years: salary tripled but expenses also tripled, I want to tell seven things to my Taiwanese colleagues

A Taiwanese employee claiming to have served at TSMC in the United States for three years recently posted in the Facebook group “TSMC Major and Minor Affairs,” listing seven points of personal experience, directly pointing out that the apparent threefold salary is significantly eroded by inflation, taxes, and tips, and that promotion policies favor local employees sevenfold.

• Tripled salary, how much is left after deductions
• Contract in hand, boss can still send you home
• Promotion ceiling: 70% Americans prioritized
• Management culture clash: Taiwanese style vs American style
• Who is suitable to go, who should think twice

A salary three times higher on paper, but how much do you actually bring home? A Taiwanese employee claiming to have worked at TSMC’s Arizona plant for three years recently posted in the Facebook group “TSMC Major and Minor Affairs,” depicting the reality of the U.S. factory through seven personal observations. The comment section quickly formed two opposing camps.

The core question of this post is not whether TSMC’s U.S. factory is good or bad, but whether it’s worth it for Taiwanese dispatched employees.

Tripled salary, how much is left after deductions

The poster pointed out the first trap in calculation: the U.S. salary figures are about three times those in Taiwan, but almost all consumer goods there are also two to three times more expensive than in Taiwan. Dining out requires an 18% to 20% tip, and after checkout, sales tax is added. These fixed expenses are almost nonexistent in Taiwan.

More critically, the bonus structure. The poster notes that under the Host Plus plan, dividends and year-end bonuses in Taiwan cannot be directly received because the company offsets these with housing and transportation subsidies provided by the U.S. plant. “The company is now at a peak profit, and coming to the U.S. doesn’t necessarily mean earning much more,” he wrote.

However, commenters also rebutted: “You definitely get more than the Taiwan dividends + housing and car allowances + COLA + year-end bonus.” He further explained that the 3+3 dispatch structure is the current norm, with promotions calculated separately, and local employees’ quotas do not take up dispatch employees’ quotas, “so your return is reasonable.”

Both sides have their reasons, but the details are not equally transparent, making it difficult for outsiders to verify.

Contract in hand, boss can still send you home

The third point raised by the poster involves labor protections, with a noticeably stronger tone.

He states that the company asks employees if they are willing to renew their contracts on the surface, but in reality, it can terminate contracts two months before expiration citing “Business Need,” and such reasons are difficult to contest under U.S. labor law. “Don’t think signing a contract means the boss won’t send you back home; nothing is impossible.”

He also mentions the issue of expanding work scope: because of higher wages at the U.S. plant, management requires employees to cross-site learnings, with one person handling the workload of two plants. “When did semiconductor expertise turn into McDonald’s employee training?” This remark resonated with many in the post.

Promotion ceiling: 70% Americans prioritized

On promotion, the poster’s answer is straightforward: “Everything is American priority, after all, the big boss’s goal is 70% Americans.”

TSMC’s U.S. plant’s localization strategy indeed sets long-term targets for the proportion of local employees, and they are actively recruiting locally in Arizona. For Taiwanese dispatched employees, this means their presence at the U.S. plant is temporary, not a long-term rooted starting point.

Management culture clash: Taiwanese style vs American style

Additionally, the poster describes his three-year experience as “bizarre,” especially highlighting the cultural gap in management styles.

Taiwanese management emphasizes discipline and execution, while American employees tend to have a more flexible work rhythm. When American colleagues leave after one or two years, Taiwanese employees often feel confused: “Thinking about being at TSMC for over ten years and being treated like this makes you feel cold.”

Who is suitable to go, who should think twice

The poster does not entirely dismiss the opportunity to go to the U.S. but clearly distinguishes two types of people: those wanting to broaden their horizons and enhance their resumes, whom he “highly recommends”; but for those expecting to significantly increase wealth, he advises “think twice.”

Commenters also listed three types of people suitable for going:

• Single young people seeking to broaden their horizons
• Couples who have obtained U.S. citizenship through childbirth
• Those moving with young children to naturally learn English

His conclusion: “If you meet any of these three, it’s worth the trip, no need to complain.” As for promotion and bonuses, he characterizes them as “extra benefits; if you get them, consider it ancestral blessing; if not, it’s just fine.”

TSMC’s localization efforts in the U.S. are still ongoing. For Taiwanese engineers choosing to go to the U.S., the salary gap has been widely discussed, but what’s harder to quantify are the contract uncertainties, promotion structures, and cultural adaptation costs accumulated over time. Compared to career development paths at Taiwan’s main plant, which is better remains a highly personal judgment.
