Hi oaky
You can pay the salaries gross and pay over the PAYE and PRSI for September in October.
You should not give yourself loans of net cash. It's too complicated and if anything happens the company, these will look very bad.
Have you by any chance given personal loans to the company? If so, these can be repaid first before payinging yourself taxable salary.
If there is any question mark over the future of the company, repaying loans could be seen as preferential treatment of creditors. And presumably overpaying salary would be frowned on too.
