How do I switch banks without a huge hassle?

Open the new account first and keep the old one open during the transition so nothing bounces. Make a list of everything tied to the old account — direct deposit, automatic bill payments, subscriptions, and any linked transfers — and update each one to the new account. Move your direct deposit by giving your employer the new routing and account numbers, then leave a small balance in the old account for a month or two to catch any stragglers. Once you've confirmed all deposits and payments are flowing to the new bank, drain and close the old account in writing and keep confirmation. Doing this methodically avoids missed payments and surprise overdrafts. If you're switching to chase a better APY for your emergency fund, confirm the new account is fee-free and FDIC-insured before you move the money.
