Business \ Tax Question

[Ron-Mexico]

Hopefully someone can give me the answer.

Basically I have done work for a company for 2007 and want to get paid in the year 2007 for tax reasons. The company I work for might not be able to pay until the middle of January 2008.

How does that work? Do they SHOW that they paid me for 2007 somehow so I can claim it on my 2007 tax return?

Basically I don't want to skip a year and then have double payments in 2008 on tax return.

Thanks
