You cannot refuse to send a check at maturity, but you can make your minimum CD $ enough to justify a check. For example, our minimum 14-day CD is $10,000 which currently pays almost $20 per fortnight. The unintended consequence of a $1,000 minimum would make each interest payment <$2.
And, on the other end of the spectrum, if you don't require interest payment at least annually, you must deal with OID for 1099 reporting.
