Will I be affected if my fiances owes Payroll Taxes to IRS, after she will close the company.

This question should be posed to a tax attorney, not a family law attorney.  I would be tempted to say that a pre-marital debt remains the debt of the person who incurred it, and does not become the responsibility of a spouse after-the-fact.  That, however, may not be the way a tax attorney or the IRS would look at things.
