## How much income is there in Karatsu?

**For FY2025, Karatsu City had taxable income of ¥151,383,092 thousand (about ¥151.38 billion) and 50,990 people liable for the income-based portion of the municipal resident tax ([MIC, Survey of Municipal Tax Assessments FY2025](https://www.soumu.go.jp/main_sosiki/jichi_zeisei/czaisei/czaisei_seido/ichiran09_25.html), municipal breakdown, Table 11). Dividing taxable income by the number of taxpayers gives ¥2,968.9 thousand per taxpayer (our calculation). Saga Prefecture estimates Karatsu's municipal income per person at ¥2,683 thousand for FY2022 ([Saga Prefecture, Municipal Economic Accounts FY2022](https://www.pref.saga.lg.jp/toukei/kiji0038130/index.html)).**

This page was made by Karatsu Farm & Food as part of the Karatsu Data Bank. It lists figures on income in Karatsu as published by MIC and Saga Prefecture, without conclusions or evaluation. Where we have divided, summed or sorted figures ourselves, we say so.

"Income" figures differ in what they cover depending on the statistic, so this page keeps two apart. The first is "taxable income", the total income of people who pay the income-based portion of the individual resident tax, published every year by MIC for each municipality. Because that tax is levied on the previous year's income (Article 313(1) of the [Local Tax Act](https://laws.e-gov.go.jp/law/325AC0000000226)), the FY2025 figure is based on income earned in 2024. The second is "municipal income", estimated by Saga Prefecture for each municipality from the prefectural accounts; it includes corporate income.

## Saga's 20 municipalities compared (taxable income)

We divided FY2025 taxable income by the number of taxpayers for each of Saga's 20 municipalities (our calculation). Karatsu, at ¥2,968.9 thousand, is ninth highest of the 20. The total for the 20 municipalities is ¥3,128.0 thousand, and for all municipalities in Japan ¥3,875.0 thousand.

MIC's notes define those surveyed as people liable for tax "after tax credits and before reductions" ([FY2025 notes](https://www.soumu.go.jp/main_sosiki/jichi_zeisei/czaisei/czaisei_seido/pdf/J51_25_note.pdf)), and give the FY2024 income-based tax amount after deducting, among other things, the "special flat-rate deduction" ([FY2024 notes](https://www.soumu.go.jp/main_sosiki/jichi_zeisei/czaisei/czaisei_seido/pdf/J51_24_note.pdf)).

## Notes on reading the figures

Taxable income is the total income of people liable for the income-based portion of the resident tax; it excludes people who do not pay that portion (those with low income or whose liability is removed by tax credits). The per-taxpayer figure is therefore not an average over everyone living in a municipality. MIC's table has rows for the municipal and the prefectural resident tax; this page uses the municipal row.

Taxable income per taxpayer, the totals for Saga and Japan, and the order of municipalities are our calculations from MIC's municipal table. The Japan total adds the 1,741 rows of that table (including Tokyo's special wards); its number of taxpayers matched MIC's summary table.

Municipal income per person includes corporate and property income and is divided by the whole resident population, including children and older people. Because its definition and year differ from taxable income, this page does not compare the two in one table. A statistical table on Karatsu City's website (14-1, from Saga Prefecture) shows FY2022 municipal income per person as ¥2,560 thousand, which differs from the figure on this page (¥2,683 thousand, Saga Prefecture's version corrected on 18 August 2026).

## What this page does not cover

It does not cover our own projects either.
