Resources

The Resource section is an area for our clients to have easy access to forms, tools and information necessary to process payroll. Under the form download section you will find all the necessary forms, from access authorization to conversion and tax forms, that are easy to download.

In addition to these forms we have provided two Calculators offering a quick reference for computing employee's paychecks or gross-up information.

IOI's newsletters can be a good reference tool. They include examples of how IOI's services have streamlined payroll processing for employers and introduce a variety of services available to help maximize the employer's experience.
