I'm going to be transferring within my company from the Washington, DC area to San Francisco. I've received a transfer package which includes the relocation package. I'm not sure what the rules are from a tax perspective, but I thought there were slightly different tax rules based on relocation expenses. The package I have received from my employer is is a lump sum bonus and it will be paid for by the San Francisco office. What tax rate would this be taxed at? Are there any additional tax implications based on the fact that it's a relocation package?
