Hi @nick.a.richter and thanks for your question!
I can’t speak to any specific case, but in general, a card issuer won’t care if a business credit card is used for a personal expense. That’s between the employee making the purchase (in this case, you) and the employer who owns the card account (in this case, ALSO you).
It’s not uncommon for employers to allow employees to use business cards for personal expenses, as long as they reimburse the employer for their spending. And that’s exactly what would be happening here. As long as the purchase doesn’t violate the terms of the bonus offer, you shouldn’t have a problem.
The specific rules for earning the bonus on that card are as follows. There are exclusions for certain types of purchases but no requirement than all purchases be business expenses:
You will receive 50,000 bonus points with this bonus offer, which can be redeemed for $500 cash back. To qualify and receive your bonus, you must make Purchases totaling $3,000 or more during the first 3 months from account opening. (“Purchases” do not include balance transfers, cash advances, travelers checks, foreign currency, money orders, wire transfers or similar cash-like transactions, lottery tickets, casino gaming chips, race track wagers or similar betting transactions, any checks that access your account, interest, unauthorized or fraudulent charges, and fees of any kind, including an annual fee, if applicable.) After qualifying, please allow 6 to 8 weeks for bonus points to post to your account. To be eligible for this bonus offer, account must be open and not in default at the time of fulfillment.
Of course, it’s always good bookkeeping practice to separate your personal and business expenses, as you indicate you will do with this card going forward. In your business records, make sure to clearly indicate that this item was a personal purchase so you don’t wind up trying to deduct it as a business expense.
