控除証明書 — deduction certificate

What it is

Proves how much you paid during the year for life insurance, earthquake insurance or 国民年金. It is usually a postcard. It is not a bill.

What to do

Keep it and attach it to the insurance form of the year-end adjustment, or to your tax return.

If you ignore it

You lose the deduction and pay more tax. For a copy, contact the insurance company or the 年金事務所.
