As a Postmate, you are an independent contractor. That means that you're responsible for any spending that takes place while doing a delivery on the platform, including parking tickets & fees, moving violation tickets, and ATM fees. However, you may be able to claim these fees on your tax filings as business expenses, and thus may be eligible for tax relief when you file your taxes.
For Postmates in San Francisco and Miami who get a ticket, we offer a partnership with TIKD, which guarantees no points on your license or your money back, avoidance of late fees, and interest-free payment plans. All TIKD related questions can be submitted directly at firstname.lastname@example.org.
