(3) The rate stated where the row found under (2) intersects the "Rate to be applied to the amount of the bonus" column is the rate sought. (ii) In the case referred to in (i), if the salary income earner's return for deduction for Dependents, etc. states that the Resident is a Person with a Disability, a widow, a single parent, or a working student (if the working student is a person set forth in Article 2, paragraph (1), item (xxxii), (b) or (c) (Definitions), where, in addition to that declaration stating that the Resident is a working student, the documents prescribed in Article 194, paragraph (4) have been submitted or presented), the number obtained by adding one person to the number of dependents and similar persons for each of these categories that applies, and, if that declaration states that there is, among the Resident's spouse in the same household or dependents, a Person with a Disability or a cohabiting Person with a Particular Disability as prescribed in Article 85, paragraph (2) (Timing for Determining Dependents and Similar Matters) (if the Person with a Disability or the cohabiting Person with a Particular Disability is a relative residing outside Japan, limited to a Person with a Disability or a cohabiting Person with a Particular Disability for whom the documents prescribed in Article 194, paragraph (5) have been submitted or presented), the number obtained by adding one person to the number of dependents and similar persons for each such person, is, respectively, the number of dependents and similar persons.
