Tips & Gotchas

• →You can skip direct deposit entirely: 12 debit card purchases within 60 days satisfies the requirement on its own.
• →Sign up for eStatements early. It is both a bonus requirement and how you waive the $5 monthly fee.
• →This is a renewal of the same $350 program from earlier in 2026, just extended through September 30, 2026.
• →The online application (openaccount.fnbsf.com) sits behind a bot-detection wall, so confirm the offer on the bank's own make-the-switch page before applying.
• →FNBSF is a small South Dakota bank. The bank's own terms do not state a residency restriction, but its branch network is concentrated in the SD/IA/MN/ND/NE area, so confirm online approval works from your state before counting on it.
