If you accept a new job or transfer to a new location, most companies, large and small, will pay your basic moving costs. Big companies generally have formal policies on what’s covered. Smaller companies will usually pay IF ASKED.
You have your best shot at full reimbursement if you talk about this problem before taking the job. The more eager the company is to have you, the more it will be willing to pay the transfer cost — even if it means payment beyond their written rules. Transferred employees often get more help than people newly hired. Again, it depends on what you ask for and how strongly the company feels about hiring you. On your moving request list should be house hunting trips for you and your spouse; packing, moving and unpacking; furniture storage and interim living expenses.
Moving a family is an important cost factor when transferring to a new job and should be treated as a legitimate expense.
