Can we use a "in care of" address on the tax return?

We live overseas for 10 or 11 months but want the correspondence from the IRS to go to our neighbor in the USA. Is that possible? We are afraid any mail to the place where we live overseas might get lost. Please advise. We also don't want it to be misunderstood that we live at our neighbor's address, but rather that we are using it as "in care of". Please advise. Thank you.
