Help using the calculators

You cannot download the calculators to your computer to use offline. Because payroll tax rates and thresholds can change, using the online calculators will guarantee you are using the most up-to-date version.

Blank screen when using a calculator

If you are using Internet Explorer and have AVG AntiVirus installed on your computer, the AVG add-ons may be affecting Adobe Reader. You may want to consider removing these add-ons to see if this solves the issue.

To remove AVG add-ons:

1. Open Internet Explorer.
2. Go to Tools > Internet options > Programs.
3. Click on Manage add-ons.
4. Untick AVG SafeSearch, AVG Security Toolbar and AVG Security Toolbar BHO.
5. Close Internet Explorer.
6. If this doesn't work, right-click on the AVG User Interface, double-click on the LinkScanner and untick Enable AVG Search-Shield and Enable Active Surf-Shield.

Remember to re-enable the add-ons when you have finished using OSRconnect. You should contact your IT or system administrator for advice if you intend to leave the anti-virus add-on permanently disabled.
