How Much Retirement Income Is Taxable? Lump-Sum vs. Monthly: The Biggest Tax Mistake Retirees Make

After decades of hard work, receiving a lump sum retirement payout can suddenly add millions of yen to your bank account—raising concerns about a large tax bill from the tax office. Would switching to monthly payments reduce your tax burden? The answer isn't just about how much you receive; you must first distinguish whether it's Labor Insurance Old-Age Benefits or retirement severance pay. The Ministry of Finance has announced the 2026 (Minguo 115) retirement income tax standards: the first tax-free threshold for lump-sum payments is now '206,000 JPY × years of service,' and for installment payments, it's 894,000 JPY annually. However, exceeding these thresholds means retirement income is recognized—not that tax is automatically owed.

Is retirement income taxable? First, distinguish between 'Labor Insurance' and 'Retirement Fund'

The commonly heard 'Labor Insurance Old-Age Benefits' and 'Labor Retirement Fund' may both be key income sources after retirement, but their tax treatments are completely different. Labor Insurance Old-Age Benefits are tax-exempt. According to the Labor Insurance Bureau, Article 4, Paragraph 1, Item 7 of the Income Tax Act states that labor insurance benefits are exempt from income tax, so they do not need to be included in personal comprehensive income tax filings.

The amounts that do require retirement income tax calculations include retirement bonuses, severance pay, retirement allowances, departure payments, lifetime pensions, and non-insurance pension benefits. The Labor Retirement Fund under the new system is also subject to retirement income tax rules when withdrawn.

Therefore, the most common mistake retirees make is treating 'Labor Insurance' and 'Labor Retirement Fund' as the same type of retirement income for tax purposes. Labor Insurance Old-Age Benefits are tax-free; Labor Retirement Fund payouts are taxed based on withdrawal method and amount.

How much lump-sum retirement income is tax-free in 2026? Calculate using '206,000 JPY × years of service'

According to the Ministry of Finance’s 2026 (Minguo 115) standards, lump-sum retirement income is calculated in three tiers:

Tier 1: Up to 206,000 JPY × years of service → Taxable income: 0 Tier 2: Exceeding 206,000 JPY × years, but less than 414,000 JPY × years → 50% of the excess is counted as retirement income Tier 3: Exceeding 414,000 JPY × years of service → 100% of the excess is counted as retirement income

In other words, the amount at which taxable retirement income begins varies by individual years of service.

Example: 20 years of service: 206,000 JPY × 20 = 4.12 million JPY 30 years of service: 206,000 JPY × 30 = 6.18 million JPY 40 years of service: 206,000 JPY × 40 = 8.24 million JPY

This means a worker with 30 years of service receiving up to 6.18 million JPY in a lump sum in 2026 would have zero retirement income under this formula.

What if you receive 8 million JPY lump-sum? Not the entire 8 million is taxed

Assume a worker with 30 years of service receives 8 million JPY in a lump sum in 2026. For simplicity, assume the entire 8 million JPY qualifies as retirement income.

First threshold: 206,000 JPY × 30 = 6.18 million JPY Second threshold: 414,000 JPY × 30 = 12.42 million JPY

Since 8 million JPY falls between 6.18 million and 12.42 million JPY, the entire 8 million is not taxable. Only 50% of the amount exceeding 6.18 million JPY is counted:

(8,000,000 JPY – 6,180,000 JPY) × 50% = 910,000 JPY

Thus, although the retiree receives 8 million JPY, the calculated retirement income is only 910,000 JPY. The Ministry of Finance uses a tiered calculation for lump-sum payments—exceeding the tax-free threshold does not mean the entire amount becomes taxable.

How much monthly retirement income is tax-free? The actual threshold is '894,000 JPY annually'

For installment retirement income, the 2026 calculation differs.

The Ministry of Finance states that for Minguo 115, recipients of installment retirement income must use:

Annual total received – 894,000 JPY = Retirement income

Thus, if the annual total is 894,000 JPY or less, retirement income is zero.

For easier understanding, dividing 894,000 JPY by 12 months:

894,000 JPY ÷ 12 = 74,500 JPY per month

However, this 74,500 JPY is not the 'monthly tax-free threshold' defined by tax law. It is merely an average monthly figure derived from the annual amount.

Under the new Labor Retirement Fund system, although it's called a 'monthly pension,' payments are actually disbursed quarterly by the Labor Insurance Bureau—so you cannot judge retirement income based on a single month’s deposit.

Does receiving an average of 80,000 JPY monthly mean high taxes?

Assume an installment retirement payout totals 960,000 JPY annually (about 80,000 JPY monthly).

Under 2026 standards:

960,000 JPY – 894,000 JPY = 66,000 JPY

Thus, 66,000 JPY is counted as retirement income. For 1.2 million JPY annually:

1,200,000 JPY – 894,000 JPY = 306,000 JPY

Retirement income is 306,000 JPY.

This is where the misunderstanding about 'how much retirement income triggers tax' arises. The 894,000 JPY is the threshold for calculating retirement income, not the final starting point for comprehensive income tax.

Does exceeding 894,000 JPY annually always mean tax is owed? Not necessarily

For example, with 960,000 JPY in annual installment retirement income, 66,000 JPY of retirement income is generated. Only this 66,000 JPY is included in comprehensive income tax calculations.

Comprehensive income tax considers the entire household’s income, exemptions, and deductions. Therefore, having retirement income does not automatically mean tax is owed. The tax amount is calculated based on net taxable income after deductions.

Thus, the interpretation 'tax starts when monthly exceeds 74,500 JPY' is inaccurate. The correct understanding is:

In 2026, installment retirement income exceeding 894,000 JPY annually begins generating retirement income; whether tax is ultimately owed depends on the overall tax filing result.

Does the 6% withheld mean the tax rate is 6%? Not exactly

Another common misunderstanding among retirees is the number '6%'.

The Ministry of Finance requires that when paying retirement income to residents in Taiwan, a 6% withholding tax is applied to the amount remaining after subtracting the fixed tax-free allowance.

However, this 6% is a 'withholding rate,' not the retiree’s final income tax rate. The pre-withheld tax and the final tax amount from annual comprehensive income tax settlement are two different things.

For example, with a lump-sum Labor Retirement Fund payout, the Labor Insurance Bureau typically withholds 6% of the taxable retirement income for domestic residents. If the amount to be withheld is under 2,000 JPY, no withholding is required.

Is the 6% self-contribution to the Labor Retirement Fund completely tax-free when withdrawn? Many get this wrong too

Many workers use the 6% self-contribution to the Labor Retirement Fund for tax savings, but 'not taxed now' does not mean 'never taxed upon withdrawal'.

The Labor Insurance Bureau explains that voluntary contributions made under the Labor Retirement Fund Act, up to 6% of salary, are not included in wage income for that year and are tax-exempt. However, the self-contributed amounts and their earnings that were not taxed at contribution are combined with employer contributions and earnings upon retirement withdrawal. Any amount exceeding the annual tax-free threshold in the year of withdrawal is considered retirement income.

In other words, the 6% self-contribution offers a 'tax advantage at contribution,' but upon withdrawal, it is subject to that year’s retirement income tax rules. It cannot be assumed that the entire self-contribution is permanently tax-exempt.

2026 retirement tax-free thresholds increased—don’t use 2025 figures

Searching online for retirement tax rules reveals various numbers.

In 2025 (Minguo 114), the lump-sum threshold was 198,000 JPY × years, the second tier was 398,000 JPY × years, and installment payments had an annual threshold of 859,000 JPY.

In 2026, these have increased to:

Lump-sum Tier 1: 206,000 JPY × years Lump-sum Tier 2: 414,000 JPY × years Installment: 894,000 JPY annually

Therefore, for retirement income received in 2026, the Minguo 115 standards must be used—do not directly apply the previous year’s 198,000 JPY or 859,000 JPY.

Is lump-sum or monthly retirement better for reducing taxes?

Based solely on the income tax formula, you cannot definitively say which method—lump-sum or monthly—is always more tax-efficient.

The lump-sum tax-free allowance increases with 'years of service'—for example, in 2026, someone with 30 years of service has a first-tier threshold of 6.18 million JPY. The installment method allows an annual deduction of 894,000 JPY. The two systems use fundamentally different calculation methods.

Additionally, if both lump-sum and installment payments are received in the same year, the deductible amounts must be prorated based on the proportion of each type received—you cannot fully apply both tax-free allowances separately.

Therefore, when retirees evaluate lump-sum vs. monthly options,
