OVERVIEW
France is cheaper than Japan at every income level, with the advantage most pronounced at €60,000 (€4,200/year). Japan's two-tier income tax system — national income tax (5%–45%) plus jūminzei resident tax (approximately 10% flat on prior-year income, comprising 6% prefectural + 4% municipal) — combined with employee social insurance contributions (pension 9.15%, health ~5%, employment insurance 0.6%) produces total effective rates that exceed France's across all benchmarks. At €90,000: France saves €2,500/year. The two countries converge at the top: both headline rates reach ~45%–55% effective at €150,000, making France €3,600/year cheaper — a relatively modest gap at that income level.

France Pros & Cons

+ PROS
  • Cheaper at every income level: France saves €400–€4,200/year versus Japan. The largest advantage is at €60,000 (€4,200) where Japan's national income tax plus jūminzei plus employee pension and health contributions combine to produce a significantly higher effective rate than France's 30% income tax bracket plus CSG/CRDS
  • Family quotient (quotient familial): France splits household taxable income by fiscal parts (1 per adult + 0.5 per child), substantially reducing the average rate for families. Japan's income tax system includes dependent deductions (扶養控除) and spousal deductions (配偶者控除) — but France's household splitting mechanism provides more systematic relief for multi-child households
  • Impatriés régime for qualifying professionals: Article 155 B CGI provides a 30% income exemption for employees transferred from abroad for up to 8 years. Japan's system does not offer a comparable flat-percentage expat exemption on employment income — though Japan's tax treaty network and the ability to deduct foreign taxes provides some relief for international workers
  • No exit tax on personal financial assets: France does not impose an exit tax on personal financial asset gains for individual shareholders (corporate/significant shareholding exit tax applies separately). Japan's kokunai iju-sha exit tax applies to Japanese tax residents departing with financial assets above ¥100 million (~€600,000) — a significant potential cost for long-term Japan residents leaving the country
− CONS
  • CSG/CRDS 9.7% with partial non-deductibility: France applies 9.7% social levies on most income, with ~2.9% non-deductible for income tax. Japan's employee health and pension contributions are fully deductible from taxable income — making Japan's employee SS burden marginally more tax-efficient than France's
  • Wealth tax (IFI) on real estate above €1,300,000: France's IFI applies to net real estate above €1,300,000 at 0.5%–1.5%. Japan has no annual wealth tax on financial or real estate assets. For investors with large French real estate portfolios above the threshold, IFI is a recurring annual cost
  • More complex compliance for foreign-source income: French residents must declare worldwide income with detailed sourcing — investment income, rental income, and dividends from Japanese sources all require DGFiP filing with correct treaty credits. Japan's tax return (kakutei shinkoku) is also complex for salaried employees with non-employment income
🇯🇵

Japan Pros & Cons

+ PROS
  • Jūminzei (resident tax) is paid on prior-year income: Japan's municipal/prefectural resident tax (~10%) is assessed on the prior year's income and paid June–May the following year. For someone arriving in Japan: no resident tax is due in the first year of residence, creating a one-year cash flow advantage. For departing residents: the remaining balance can be paid upfront
  • Shakai hoken (social insurance) is employer-split: Japan's pension (kosei nenkin) is split equally at 9.15% employee / 9.15% employer. Health insurance (kenko hoken) ~5% employee / ~5% employer. This creates a very high employer cost (~25–30% of gross) but means employee take-home is partially better than a system where the same amounts were employee-only
  • No capital gains tax on principal residence: Japan exempts gains on the sale of a principal residence from income tax up to ¥30 million (~€180,000) exclusion. Additional long-term hold rules reduce the tax further. France also exempts the primary residence — but Japan's exclusion threshold is higher
  • Retirement savings (iDeCo / NISA): Japan's iDeCo (individual defined contribution pension) allows tax-deductible contributions of ¥23,000–¥68,000/month depending on employment type. NISA (Nippon Individual Savings Account): ¥3.6 million/year investment limit (new NISA from Jan 2024) with tax-free growth and withdrawals. Both are more generous in contribution terms than France's PER (plan d'épargne retraite)
− CONS
  • Jūminzei ~10% applied on top of national income tax: Japan's resident tax is a flat ~10% of taxable income (after deductions) applied across almost all income levels. At €60,000: jūminzei adds approximately €4,500 on top of national income tax — this single addition largely explains why Japan is more expensive than France at this income level
  • Employee pension contribution (kosei nenkin) 9.15% up to ~€65,000 insurable earnings: Japan's pension contribution ceiling is ¥650,000/month salary (approximately €3,900/month or ~€46,800/year ceiling). For earners up to ~€46,800: the full 9.15% applies. Above this: no additional pension contribution — slightly favouring Japan at very high incomes, though resident tax still applies throughout
  • Employee health insurance ~5% with regional variation: Japan's employee health insurance rate varies by prefecture and industry (Kyokai Kenpo covers most private sector employees). The combined employer + employee rate is approximately 10%, with the employee bearing ~5%. This rate has been rising and varies by the insured's salary grade
  • Inheritance tax — progressive to 55%: Japan's inheritance tax reaches 55% on amounts above ¥600 million (~€3.6M) per heir, with a basic exemption of ¥30M + ¥6M per heir. For residents in Japan with global assets: Japan taxes worldwide estate assets. France's droits de succession reaches 45% for direct descendants (after €100K exemption). Japan's top rate is higher
FAQ

Frequently Asked Questions

Is France or Japan cheaper for income taxes?

France is cheaper than Japan at every income level in 2026. At €30,000 the saving is small (€400/year). At €60,000 France saves €4,200/year — the largest gap in the comparison. At €90,000: France saves €2,500/year. At €150,000: France saves €3,600/year. Japan's jūminzei (resident tax ~10% flat) applied on top of national income tax is the primary reason for the difference — France has no direct equivalent flat-rate levy of this size.

What is Japan's jūminzei (resident tax) and how does it affect the comparison?

Japan's jūminzei (住民税 — resident tax) is a prefectural + municipal income tax totalling approximately 10% of taxable income, assessed on the prior year's earnings. The standard split is 4% municipal + 6% prefectural. It applies after most deductions but with no threshold exemption for employment income above basic levels. At €60,000 gross: jūminzei adds approximately €4,500 to Japan's total tax burden on top of national income tax — this single levy explains most of the €4,200 gap between France and Japan at this income level.

How does Japan's iDeCo compare to France's PER retirement savings?

Japan's iDeCo (individual defined contribution pension) allows monthly contributions of ¥12,000–¥68,000 depending on employment type and existing corporate pension coverage — all deductible from taxable income. Annual maximum: ¥816,000 (~€4,900) for self-employed individuals. France's PER (plan d'épargne retraite): deductible contributions up to 10% of prior-year professional income (to a 2026 ceiling of €37,094). For most salaried professionals: France's PER contribution room (typically €3,000–€10,000+/year for mid-high earners) is larger than Japan's iDeCo limit. Both provide tax deferral on contributions and investment growth.

How does Japan's NISA compare to France's PEA investment account?

Japan's new NISA (from January 2024): annual investment limit ¥3.6 million (~€21,600) with no lifetime cap on the growth account (seichō tōshi) portion; tax-free indefinitely. France's PEA (Plan d'Épargne en Actions): lifetime contribution cap €150,000; investments held 5+ years are tax-free on withdrawal except 17.2% social levies. Japan's NISA offers higher annual limits and permanent tax-free status. France's PEA applies only to EU-listed equities; Japan's NISA covers most listed securities. Both are excellent vehicles — NISA has an edge in scale, PEA in the scope of withdrawal exemption.

What is Japan's exit tax and who does it affect?

Japan's exit tax (国外転出時課税) applies when a Japanese tax resident who has lived in Japan for more than 10 years in the past 15 years departs with financial assets exceeding ¥100 million (~€600,000). Unrealised capital gains on shares, bonds, and certain other assets are deemed realised on departure and subject to capital gains tax at 15.315%. France has no equivalent personal financial asset exit tax for individual shareholders. For Japan long-termers with significant listed share portfolios: the exit tax is a meaningful cost that French residents moving to Japan should plan for from day one.

How does France's inheritance tax compare to Japan's?

Both countries impose significant inheritance taxes but with different structures. France: basic exemption €100,000 per heir from each parent (every 15 years); rates 5%–45% for direct descendants; up to 60% for unrelated heirs. Japan: basic exemption ¥30M + ¥6M per heir; rates 10%–55% on amounts above the exemption per heir. For a €2M estate split between two children: France ~€0 (within exemptions per transfer); Japan: approximately €17,500 total (depending on exchange rates and exact asset values). Japan's higher headline rate (55%) applies at thresholds well above what most earners accumulate. Both countries have complex rules for cross-border estates.

What are the visa options for French citizens moving to Japan?

French citizens need a visa to live and work in Japan — there is no EU/EEA freedom of movement. Main work visa categories: Engineer/Specialist in Humanities/International Services (most common for office workers), Highly Skilled Professional (points-based, preferential treatment including faster permanent residency pathway), Specified Skilled Worker. Japan's Digital Nomad Visa was announced for 2024–25 and allows remote workers to stay up to 6 months. Permanent residency: typically requires 10 years of continuous residence (5 years with highly skilled professional status). Japanese language is generally required for daily life but not mandated for work visas.
