This is the solution I came up with when commenting on Bozho

int handleAllowance(LocalDate today) {

    int allowance = membership.allowance();
    if (allowance == 0) return 0;

    // calculate month difference
    int allowanceMonths = Months.monthsBetween(lastAllowanceUpdate.withDayOfMonth(1), today.withDayOfMonth(1)).getMonths();

    // if update was last month or earlier
    if (allowanceMonths > 0) {

        // ...and if today is on or past update day
        int updateDay = Math.min(allowanceDay, today.dayOfMonth().getMaximumValue());
        if (today.getDayOfMonth() >= updateDay) {

            // give credits (multiply with months in the rare case this process consecutively fails to run for 2 months or more)
            final int totalAllowance = allowance * allowanceMonths;
            giveCredits(totalAllowance);

            // update day
            lastAllowanceUpdate = lastAllowanceUpdate.plusMonths(allowanceMonths);

            // return the allowance given
            return totalAllowance;

        }

    }

    return 0;
