No. A projected tax result does not reduce the published government commitments or establish family eligibility.
Budget the actual intended applicants
The FAQ recommends initially including the eligible spouse and unmarried children under 21 who will join. Each adds US$15,000 and US$1 million, including with corporate sponsorship. Assess any tax questions using the actual payer and transaction rather than assuming a shared household produces a particular credit or refund.
Collect passports, marriage records, birth records, and evidence relevant to marital status and age, then confirm the current programme rules and underlying immigrant-law treatment before relying on a household budget. A second child, a child reaching an age threshold during the process, a marriage, or a separation each alters who is included and therefore the total, and a budget written around a fixed household will not answer the question when it arises. An adult child, a partner who is not legally married, a stepchild, a child approaching twenty-one, or a family member with their own immigration history each deserve an individual answer rather than an inference from the general description.
