Life Insurance Premium Deduction Calculator
Enter your annual life insurance premiums for the general, nursing-care-medical, and individual pension categories to automatically calculate Japan's life insurance premium deduction (income tax and resident tax) under both the new and old systems.
The life insurance premium deduction is an income deduction that lets you subtract a set amount from taxable income (for both income tax and resident tax) based on the premiums you've paid. The category breakdown, caps, and calculation tables differ depending on whether your contract was signed on or after January 1, 2012 ("new system") or before that date ("old system"). Enter your annual premiums for each category, and this tool will automatically select whichever combination of new and old rules gives the larger deduction.
New system (contracts from January 1, 2012 onward) calculation table
| Annual premiums paid | Income tax deduction | Resident tax deduction |
|---|---|---|
| ¥20,000 or less | Full amount of premiums paid | Full amount of premiums paid |
| Over ¥20,000, up to ¥40,000 | Premiums × 1/2 + ¥10,000 | Premiums × 1/2 + ¥6,000 |
| Over ¥40,000, up to ¥80,000 | Premiums × 1/4 + ¥20,000 | Premiums × 1/4 + ¥14,000 |
| Over ¥80,000 | Flat ¥40,000 | Flat ¥28,000 |
This table applies to all three categories — general life insurance, nursing-care-medical insurance, and individual pension insurance. Each category is capped at ¥40,000 for income tax and ¥28,000 for resident tax; the combined cap across all three categories is ¥120,000 for income tax and ¥70,000 for resident tax.
Old system (contracts through December 31, 2011) calculation table
| Annual premiums paid | Income tax deduction | Resident tax deduction |
|---|---|---|
| ¥25,000 or less | Full amount of premiums paid | Full amount of premiums paid |
| Over ¥25,000, up to ¥50,000 | Premiums × 1/2 + ¥12,500 | Premiums × 1/2 + ¥7,500 |
| Over ¥50,000, up to ¥100,000 | Premiums × 1/4 + ¥25,000 | Premiums × 1/4 + ¥17,500 |
| Over ¥100,000 | Flat ¥50,000 | Flat ¥35,000 |
This table applies to the two categories of general life insurance and individual pension insurance (the old system has no nursing-care-medical category). Each category is capped at ¥50,000 for income tax and ¥35,000 for resident tax.

Tips
- Your life insurance premium deduction certificate clearly states whether a policy falls under the "new system" or "old system." Even for the same "general life insurance" category, the classification can differ depending on when the contract was signed, so always check the certificate.
- If you have both new and old contracts in the general or individual pension category, the old-system-only deduction (capped at ¥50,000) can sometimes be more advantageous than combining new and old (capped at ¥40,000). This tool automatically calculates whichever option is more favorable.
- Even if your annual premiums exceed the cap for the deduction (¥80,000 under the new system, ¥100,000 under the old system), paying more in premiums will not increase your deduction any further. There's no need to increase your premiums solely to boost the deduction.
- To qualify for the individual pension insurance premium deduction, your contract must include a "tax-qualified individual pension insurance rider." A plain pension-type insurance policy without this rider may instead fall under the general life insurance category, so check your certificate carefully.

Side Note — Why the life insurance premium deduction split into "new" and "old" systems
The life insurance premium deduction is a long-standing system created in 1951. Following the introduction of a new nursing-care-medical insurance premium deduction category in the 2010 tax reform, new categories and caps came to apply to contracts signed on or after January 1, 2012. Contracts predating that reform (the old system) were left unchanged under transitional measures, retaining their original categories and caps.
The background to the new system was the fact that Japan's public nursing-care insurance system had become well established, increasing demand for private nursing-care coverage. Previously there were only two categories — life insurance and individual pension insurance — and it's said that creating a separate nursing-care-medical category was intended to encourage people to take out medical and nursing-care coverage.
At the same time, to avoid disadvantaging policyholders with old-system contracts, a mechanism was set up allowing people to choose whichever option is more favorable when both new and old contracts exist. Because life insurance contracts often involve paying premiums over many years, this kind of design — aimed at preventing sudden burden increases for existing policyholders whenever tax rules change — is a recurring theme in Japan's insurance tax policy.
