Overview 

Estimating Tax on an Opportunity with Accounting Seed (AS) Native Tax is different depending upon whether Header Level Posting (HLP) or Line Level Posting (LLP) is enabled. 

Do you want to:

• Estimate Tax on an Opportunity with Header Level Posting (HLP)
• Estimate Tax on an Opportunity with Line Level Posting (LLP)

Estimate Tax on an Opportunity with Header Level Posting (HLP)

1. Navigate to Accounting Home and click the Create Entries tab. Then, under the Revenues menu, click Opportunities.
2. Select a list view (other than the Recently Viewed list view).
3. Display an Opportunity record. 
4. Select a Product Line and click Edit. Otherwise, click Add Products to add a new line. 
5. Scroll down to the Accounting Information. 
6. In the Tax Group field, click the Lookup icon to search for and select a Tax Group. 
   
   
   
   
7. Click Save.
8. From the Opportunity record, click Calc Tax to calculate the Estimated Tax Amount based upon the selected Tax Group.
   Note: The AS Native Tax HLP functionality explicitly requires a user to click the Calc Tax button on the Opportunity, however this is not required on a Billing or Payable.
   
   
   
   
9. Click Calc Tax again to see the Tax Amount display on the Product Line.
   
   
   

Notes:

• If changes are made (including addition or deletion of lines) to the Opportunity Product Line(s), click Calc Tax to refresh the tax amount. 
• Clicking Calc Tax on a cloned Opportunity will refresh the tax amount.
• A user with a System Administrator profile can directly enter an amount into the Tax Amount field. However, this amount will be overwritten by the system anytime the Calc Tax or the Create Billing function is performed. Therefore, it is not recommended to edit the Tax Amount field directly.
