As a general rule (rule of thumb) the maximum range figure published for a jet transport type, when empty, can be reduced by 40% with a maximum payload.
Commercial operators require sufficient fuel reserves to meet their regulatory requirements, which varies from country to country.
Private operators can generally decide for themselves what fuel reserves are required, subject to much less regulatory restrictions than commercial operators.
Most private jet operators in the USA use NBAA fuel reserves, which are generally more restrictive than required by 14CFR91.

The rule tends to be that you can have max range, or max payload, but not both. If you fill up with fuel for max range, the plane becomes too heavy for max payload (not to be confused with max take off weight).
