Knowledge Base

Frequently Asked Questions

Is cash back better than points or miles?

Cash back is the most flexible reward because it's equivalent to cash. Points and miles can sometimes offer higher 'per-unit' value for travel, but they often come with redemption restrictions and complexity.

Is cash back considered taxable income?

For most personal purchases, the IRS treats cash back as a discount or rebate on the purchase price rather than income, so it is typically not taxable.

Are there limits on how much cash back I can earn?

Some cards have 'capped' categories (e.g., 5% on gas up to $1,500 per quarter), while others offer 'unlimited' flat rates. Always check your card's fine print.

When do I actually receive my cash back?

Timing varies by issuer. Some apply it to your account balance immediately, while others wait until the end of the billing cycle or until you reach a minimum redemption threshold (like $25).
