Get your taxes done using TurboTax

First .... STOP paying for any business expenses from a personal account and visa versa ... that practice will get you in deep doo doo in an IRS audit.

 

Next, for bookkeeping entries,  the expenses paid with personal funds or CC are entered as expenses on the books  with a corresponding entry to "loan from shareholder" in your liabilities account.  Same situation

for the SEP contribution.
