20 November 2024 I left my job with an Indian company and joined an US affiliate. The US company offered me a salary and a signing bonus. The signing bonus is not a part of the employment offer letter but a separate letter saying that i have to return this if i leave within one year. Later, it was decided that the signing bonus will be paid from Indian company payroll. Since it is paid from indian payroll to my indian bank account and not a part of the offer letter, Is it indian income or foreign income?
It was not reported in my US tax w2 and the indian company told me that it was documented as employee bonus in indian company records.
