How to Streamline VAT Refunds on Customs Clearance Invoices in SAP

Estimated read time 13 min read

Managing VAT on imports can be a tricky task, especially when you’re dealing with customs clearance invoices across multiple countries. While the tax itself is usually recoverable, many companies still post it manually outside of SAP and that’s a missed opportunity for automation, accuracy, and compliance.

In this blog, I’ll Walk you through a best-practice approach I’ve used to help organizations automate VAT recovery in SAP, streamline tax reporting, and build audit-proof trails.

🚢 The Real Challenge with Import VAT

When companies import goods, they incur customs duties and VAT as part of the clearance process. These taxes are recoverable, but many businesses:

Post them manually to tax accountsAdjust VAT returns outside SAPBreak the audit trailSpend time reconciling errors at month-end

Sound familiar?

Let’s fix that.

💡 The Smarter Way: Automating VAT Recovery in SAP

Instead of treating customs clearance like an afterthought, we can treat it like any other recoverable tax. SAP gives us the tools. We just need to use them right.

Streamlining and Automating VAT Refund on Customs Clearance Invoices: A Best-Practice Guide Using SAP

Here’s a simplified version of the approach that has worked for several multinationals I’ve worked with.

✅ Step 1: Get the Basics Right (Pre-requisites)

Before you post any customs invoice, make sure your user profile in SAP has the setting “Calculate Tax on Net Amount” checked.

Why?
It simplifies the tax calculation logic and reduces manual effort.

To check this:

Go to FB60Navigate to Editing OptionsEnable Calculate Tax on Net Amount

📦 Step 2: Understand the Invoice

Here’s a sample customs invoice for importing goods into Mexico:

Description

Amount (MXN)

Assesses value of the Good imported

100000

Freight, Insurance and other expenses

10000

Assessed Value including Freight and Insurance (CIF)

110000

Import duty/fee on the Goods @ 10% on CIF

11000

Total Value of Goods including Import duty

121000

VAT Paid on the goods imported @ 16% on Total Value

19360

Customer clearing agent Fees

1000

Domestic Freight from Port to the customer location

500

Total Charges by Custom Clearing Agent

1500

VAT on custom clearing Fees @ 1600 on Total Charge

240

Total invoice amount from custom Clearing Agent (11000+19360+1000+500+240)

32100

🧮Step 3 How to Calculate Base Amount for VAT

VAT should be calculated only on the applicable charges. Here’s how:

Import VAT Base =
Value of Goods + Freight + Insurance + Import Duty
= 100,000 + 10,000 + 11,000 = 121,000 MXNAgent VAT Base =
Agent Fees + Domestic Freight
= 1,000 + 500 = 1,500 MXNThen, VAT = Base × Tax RateImport VAT = 121,000 × 16% = 19,360 MXNAgent VAT = 1,500 × 16% = 240 MXN

These base amounts must match what SAP uses when calculating tax. Input the values correctly with tax codes on the respective line items. If you’re using a tax engine (like Vertex), confirm the logic aligns with tax jurisdiction settings.

🧾 Step 4: Post the Invoice Using FB60 (Similar process while using MIRO)

Here’s what to enter in SAP:

Field Name

Mandatory or Optional

Value to be Input

Transition

Mandatory

Select Invoice (R)

Vendor

Mandatory

Enter the SAP Vendor Number for the customs clearing agent

Document Date

Mandatory

Enter the invoice date

Posting Date

Mandatory

Enter the date you are posting the invoice in SAP

Reference

Optional

Customer Clearing Agent Invoice Number

Document Type

Mandatory

Use KR (standard for vendor invoice) or the appropriate document type

Amount

Mandatory

Enter the total invoice amount as per the customs clearing invoice

Currency

Mandatory

Enter the invoice currency

Calculate Tax

Mandatory

Tick this box (essential if 3rd party tax engine is connected)

Text

Optional

Free Field to enter anything meaningful.

Line 1

Mandatory

Choose the appropriate expense GL account, set the indicator to S (Debit), enter the import duty amount from the invoice, and assign the correct cost center. Do not enter a tax code for this line.

Line 2

Mandatory

Select the correct expense GL account, set the indicator to S (Debit), enter the customs clearing agent fees from the invoice, and add the appropriate tax code and cost center. If your system uses jurisdiction-based tax calculation, also enter the tax jurisdiction code.

Line 3

Mandatory

Choose the appropriate expense GL account, set the indicator to S (Debit), enter the amount for any additional charges (e.g., freight), and include the relevant tax code and cost center. If jurisdiction-based tax is enabled, also enter the tax jurisdiction code.

Line 4 (Calculate tax on Net is ticked)

Mandatory

Select the Tax Control GL account (the balance of this account should be zero after posting), set the indicator to S (Debit), and enter the tax base amount from the previous step (when “Calculate Tax on Net Amount” is ticked). Add the appropriate tax code and cost center. If jurisdiction-based tax is enabled, also enter the tax jurisdiction code so the system can calculate the recoverable tax accurately.

Line 4 (Calculate tax on Net is not ticked)

Mandatory

Select the Tax Control GL account (the balance of this account should be zero after posting), set the indicator to S (Debit), and enter the tax base amount calculated in the previous step (when “Calculate Tax on Net Amount” is not ticked). Include the relevant tax code and cost center. If jurisdiction-based tax is enabled, also enter the tax jurisdiction code to ensure the system calculates the recoverable tax correctly.

Line 5

Mandatory

Select the Tax Control GL account (the balance of this account should be zero after posting), set the indicator to H (Credit), and enter the tax base amount calculated in the previous step (when “Calculate Tax on Net Amount” is ticked). Add the cost center.
Note:
Do not enter any tax code for this line item.

Pro Tip:
For tax control lines, the balance should net to zero after posting. Jurisdiction-based tax? Don’t forget to input that as well.

🔍 Step 5: Simulate Before Posting

Always click “Simulate” in FB60 before posting. This will:

Show you how SAP calculates the tax based on the base amountsConfirm that debits = creditsHelp verify if all tax lines are hitting the correct GL accounts

If there’s a mismatch, double-check the tax base amount and tax code settings.

🛠 Step 6: Troubleshooting Common Issues

Here are a few errors I’ve encountered—and how to fix them:

Tax not computed? → Check tax code and make sure “Calculate Tax” is selected. If you’re using a tax engine like Vertex, make sure it’s not marked as exempt.Debits ≠ Credits? → Likely due to incorrect tax base or missed settings.Multiple ship-to addresses? → Either split the invoice or handle each jurisdiction’s tax base separately.

📊 Real-World Results

In the past, companies I’ve worked with were posting these taxes manually and handling VAT adjustments offline. That led to:

Inefficient period-end closingsBroken audit trailsRisk of compliance errors

After implementing this structured approach:

Tax reports aligned automaticallyAudit trails were fully system-basedManual work dropped dramaticallyTax teams shifted focus from grunt work to strategy

In some cases, it even helped reduce FTEs in tax operations—because SAP did the heavy lifting.

🔚 Final Thoughts

If your customs VAT recovery is still manual, it’s time to modernize. This SAP-based approach ensures:

✅ Accurate reporting
✅ Faster closings
✅ Stronger compliance
✅ Less manual work

As digital tax reporting becomes more common worldwide, building these automations now will set you up for future success.
