Hello,

I am going to transfer within my company to a new city. I have negotiated 15K in reimbursement costs from my company. 9K for the full move and 6K for misc expenses (short term housing etc). My company will not pay for anything directly to these companies as they plan on cutting me a check. How should I ask for this $$$? Should it be grossed up to equal 15K or can they cut me a check for 15K without taxes and then I list it on my tax return? Any advice would be appreciated. Thanks

It isn't wages (for work) so taxes are not deducted.
You should get a 1099-MISC and you will report it as income, and then deduct what you can. See the IRS publications on moving expenses and short term housing, etc.
IRS.gov

If you get $15,000, the Form 1099-MISC SHOULD list the income in Box #3 (other income) which is reported on Line #21 of Form 1040.

You then offset the income by claiming moving expenses using Form 3903. Recognize that the allowable expenses you can claim on Form 3903 are limited, so some of your reimbursement will be taxed, even though you used it for valid moving expenses.

It will be considered taxable income. So part of your negotiation should be a gross up, otherwise you will be responsible for the taxes. If you didn't negotiate the gross up, they may not want to do it.
