Best bank bonuses in Colorado

There is no online application for this account. The only way in is to book an appointment with a KeyBank banker and open it with them, so you need to be able to reach one of KeyBank's branches. The states listed are where those branches are. KeyBank's terms for this business offer set no residency rule and exclude no state, so if you can get to a branch you can open it.

New consumer checking customers only. Ineligible with an existing Huntington consumer checking account, one closed in the last 12 months, or a consumer checking incentive received in the last 12 months.

New checking customers only. Use promo code PARKPIRATES at account opening.

New checking customers only (none in the last 12 months). Open online by December 11, 2026.

Targeted: KeyBank's terms say you must have received a personalized $500 Business Banking offer letter from them, and you open by appointment with a banker rather than online. Schedule that appointment by December 18, 2026. Make the $25 minimum opening deposit and get to $5,000 or more within 30 days, then keep a minimum daily balance of $5,000 or more for the first 90 days; if the balance dips below $5,000 even once in that window you lose the bonus. The $500 is paid within 60 days of meeting the requirements. You cannot have held a KeyBank business checking or savings account in the past 12 months, and the branch network covers AK, CO, CT, ID, IN, MA, ME, MI, NY, OH, OR, PA, UT, VT and WA. Open Basic Business Checking, which is $5 a month waived at a $1,000 average ledger balance so the $5,000 hold covers it; do not open Key Business Reward Checking, which is $25 a month and needs $7,500 to waive.

The person listed first on the account has to live in Arizona, California, Colorado, Florida, Iowa, Illinois, Indiana, Minnesota, New Mexico, Nevada, Oregon, Utah, Washington or Wisconsin at the time you apply, and BMO may ask for proof of address. You cannot already hold a BMO personal checking account or have closed one in the past 12 months, and it is one bonus per customer.

New business checking customers only, state restricted, apply by October 14, 2026. The two tiers have DIFFERENT funding deadlines: Unlimited Business Checking pays $400 for total new money deposits of $5,000 or more within 60 days of opening, while Unlimited Plus pays $1,000 only if $20,000 or more lands within 30 days and then sits at $20,000 or more for the next 60 days. Both require keeping the account open for 90 days. Plan on paying the monthly fee through the hold: Unlimited is $20 a month waived only at a $10,000 total deposit relationship, Unlimited Plus is $40 a month waived only at $50,000, and neither the $5,000 nor the $20,000 deposit clears its own threshold because the cash bonus does not count toward it.

Membership: Bellco's field of membership is Colorado, but you do not have to live in Colorado. Bellco's own page says that for interested parties outside of Colorado, joining the Bellco Foundation makes you eligible for membership. New checking customers only ('you don't have an active checking account with Bellco'); one bonus per household. Must keep the account open and in good standing for 1 year. Bellco may reclaim the bonus if you close sooner. Bonus within 90 days of the qualifying deposit.

Membership: Air Academy Credit Union, serving Colorado Springs, Monument, Castle Rock, Parker, Littleton and Highlands Ranch. You must be a Colorado resident to qualify. Personal accounts only, one per member. Not available to existing Rewards Checking holders, to members who closed an account in the past 180 days or closed one with a negative balance in the last three years, or to anyone who has already had an Air Academy checking reward or bonus. Mention the offer when you open the account or use the offer link, or you lose eligibility. The reward is credited within 60 business days of meeting the requirements, so budget roughly three months. Closing the account within 180 days costs $25. You can also open at a branch and give promo code LOCALBONUS there instead of using the offer link.

Limit one of each bonus type per account; converted accounts are not eligible. The current disclosure (eff. 9/27/25) has no new-customer restriction.
