In most day to day situations for gig workers (Uber, Postmates, Instacart), meals are not tax deductible.
However in special circumstances, meals are deductible if you meet one of these requirements:
1) you're driving out of town for business, and it would be unreasonable for you to provide food for yourself from home
2) you're sharing a meal with a potential referral or client
3) you drive for an abnormally long distance in which you’re unable to provide food for yourself due to an unexpected overnight stay
Stride Tip: Rideshare companies have referral programs that reward drivers with cash bonuses when their driver referrals sign up to drive with Uber/Lyft. Meals that you purchase while recruiting other drivers are also tax deductible! Similar to passenger goodies, only 50% of the cost for these items can be deducted.
