How to Add Tax Rates Sage 300

Prerequisites

Before you can begin entering tax rates, several key components must be in place:

• Tax Services must be activated in your Sage 300 system
• Tax authorities must be created
• Tax classes must be established
• General ledger accounts for tax reporting must be set up

Setting Up Tax Authorities

Creating Tax Authority Records

The first step is to establish your tax authorities, which represent the jurisdictions where you're subject to tax. To create a new tax authority:

1. Navigate to Common Services > Tax Services > Tax Authorities
2. Enter a unique code for the authority
3. Provide a detailed description
4. Configure the following on the Profile tab:
   • Tax reporting currency
   • Maximum tax allowable amount
   • Minimum amount for tax charging
   • Tax base
   • Report level
   • Tax in price options

Configuring Authority Accounts

On the Accounts tab, you'll need to specify the relevant general ledger accounts for:

• Tax liability posting
• Recoverable tax amounts
• Tax expense tracking

Tax Classes Configuration

Tax classes are essential components that define different categories for both sales and purchases. They provide flexibility in applying different tax rates to various types of transactions.

Types of Tax Classes

• Sales item classes
• Purchase item classes
• Customer classes
• Vendor classes

Entering Tax Rates

Step-by-Step Process

1. Access the tax rates screen by navigating to Common Services > Tax Services > Tax Rates
2. Select your configured Tax Authority code
3. Choose the transaction type:
   • Sales
   • Purchases
4. Enter the tax rates for each tax class as percentages
   • For example, enter 6.00 to represent a 6% tax rate
5. Click Save to implement the new rates

Important Considerations

New tax rates or modifications will only apply to future invoices entered after saving the changes. For existing open batches, you'll need to manually edit tax calculations using the Accounts Taxes screen in either Accounts Receivable or Accounts Payable.

Self-Assessed Tax Setup

For organizations that need to handle self-assessed taxes, follow these specialized steps:

Creating Tax Authorities for Self-Assessment

1. Create two distinct tax authorities:
   • Authority 1 for tax expense
   • Authority 2 for tax payable
2. Configure tax rates:
   • Set normal tax rate for Authority 1
   • Set negative equivalent rate for Authority 2

Implementation Steps

1. Create purchase tax classes for both authorities
2. Add both taxes to the appropriate tax group
3. Ensure identical tax classes are used for both authorities
4. When entering invoices:
   • For manual calculation: Enter positive tax amount for Authority 1
   • Enter corresponding negative amount for Authority 2

Tax Groups Management

Tax groups are essential for organizing multiple tax authorities that apply to specific transactions. They allow you to:

• Combine multiple tax authorities
• Apply different tax configurations based on geographical areas
• Manage tax calculations efficiently
