Best bank bonuses in Maine

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 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.

Must be a resident of Maine, New Hampshire, or Vermont. Open only to those who have not had a Bar Harbor consumer checking account in the last 15 months. One offer per household, and customers may take part in an account-opening promotion only once. Bar Harbor employees are not eligible.

State restricted: MA, NH, ME, RI, CT, VT. New Country Bank checking customers only.

Maine, New Hampshire and Massachusetts. You must be 18 or older, and the primary account owner cannot have owned a Camden National consumer checking account in the 12 months before opening this one. One bonus per account or individual, and it cannot be combined with any other offer.

Membership: cPort Credit Union, Maine. You are eligible if you live or work in Maine and meet one of these tests: you live or work in Cumberland, Kennebec, Sagadahoc, Androscoggin or York County; you are a current or retired public sector employee at the local, state, county or federal level; you are a current or retired member of the armed services, National Guard or reserves; or you live in the same residence as a member or as someone eligible to become one. Joining takes a $5 share deposit. Offices are in Portland, Augusta, Scarborough and Lewiston. The bonus is deposited within ten business days of your direct deposit, so allow about two weeks. No end date is stated and cPort says terms are subject to change.

HSBC Premier Relationship required, which typically means $75,000+ combined balances or a qualifying HSBC mortgage. High-balance offer, new Premier customers only. New-customer offer: account must be open by August 31, 2026 (extended; DoC 7/11/26: 'extended through 8/31/26 or 12/31/26 depending on the offer').

Open or upgrade to a new Chase Private Client Checking account by October 14, 2026. Top $3,000 tier requires $500,000+ in new money; $1,000 minimum tier requires $150,000. Requires an in-person/banker meeting to redeem the coupon.

New Chase business checking customers only. You are not eligible if your business already has a Chase business checking account, if you closed one within 90 days of opening it, or if you closed one with a negative balance in the past three years. Government entities, political action committees and campaign accounts are excluded, as are JPMorgan Chase employees. A signer can take one Chase business checking offer every two years counted from the last enrollment date, and only one offer applies per account. Chase does not open business deposit accounts for Hawaii businesses, so Hawaii owners cannot use this one. Chase business CREDIT CARDS are still available in Hawaii. Expires October 15, 2026.
