Not an expert, but been paying bills of family member for quite some time and never faced issue.
Until you're paying your taxes properly, transferring your money to any family member's (allowed) should be ok and you can pay taxes without any issues.
In case there is any enquiry you can proof source, that's all.
I pay my family's card's bill and they don't even file my ITR, no issues as the money was always deposited in my account by family and not cash.
