This is what we call a 90 letter. The 90 is the number of days from the first notice until this final notice which threatens you with levy action against your wages and bank accounts. The IRS will also be filing a tax lien if they have not already done so. This notice is a call to action and in most cases, the services of an IRS resolution specialist is needed to prevent further damage to your credit and finances. Most of the time the fear associated with the IRS is worst than the actual consequences of dealing with the problem correctly.
