change donations source

We have dual incomes.  My spouse is self-employed.  Last year, we didn't get any tax benefit from making charitable contributions from our personal account.  That would include church as well as charitable causes.  Is there any reason we can't claim those deductions as business expenses if my spouse made them from the business account?  Not doubt about it, this is an attempt and having the cake and eating it, too.

 

Thanks.
