What is Indirect Tax Compliance? A Complete Guide for Finance Professionals 

Indirect tax – such as VAT, GST and sales tax is a critical part of doing business across borders. Unlike direct taxes, which are paid directly by individuals or companies to tax authorities, indirect taxes are collected by businesses on behalf of governments, often at multiple points in the supply chain. This responsibility brings with it a complex set of compliance obligations that are constantly evolving. 

In an increasingly global and digital economy, indirect tax compliance has become more demanding than ever. Governments are tightening regulations, expanding digital reporting requirements and implementing real-time e-invoicing mandates to close tax gaps and increase transparency. As a result, finance and tax teams are under increasing pressure to get it right – every time, in every jurisdiction. 

This guide is designed to help finance professionals, tax managers and CFOs understand what indirect tax compliance really involves. Whether you’re managing multi-country VAT returns, preparing for upcoming e-reporting requirements or simply trying to reduce risk and increase efficiency, this comprehensive overview will give you the clarity and confidence to navigate today’s complex tax landscape. 

What is indirect tax? 

Indirect tax is a tax that is collected by an intermediary (typically a business) on behalf of a government and paid by the end consumer. Unlike direct taxes, which are paid directly to tax authorities by individuals or corporations (such as income tax or corporate tax), indirect taxes are embedded in the price of goods or services and passed along the supply chain until they reach the final buyer. 

Common types of indirect tax  

• Value-Added Tax (VAT): A multi-stage indirect tax applied at each point of sale or value addition, common across the EU and many other regions. 

• Goods and Services Tax (GST): Similar to VAT, used in countries like Canada, Australia and India. 

• Sales Tax: Typically, a one-time tax charged at the point of sale to the end consumer (e.g. in the United States). 

• Customs Duties: Taxes on imported goods, often levied at the border based on the value or quantity of items. 

Key differences between indirect and direct tax

Direct Tax	Indirect Tax
Paid directly by the taxpayer	Collected by a business from the buyer
Based on income or profits	Based on consumption or transactions
Examples: Income tax, corporation tax	Examples: VAT, sales tax, custom duties

Who bears indirect tax vs who remits it 

A key feature of indirect tax is that the economic burden falls on the consumer, while the administrative burden falls on the business. That means while your customers ultimately pay the tax, it’s your responsibility to calculate it correctly, collect it, report it and remit it to the appropriate tax authority. Failure to do so accurately and on time can result in fines, audits and reputational risk.

Understanding this is essential to maintaining compliance and avoiding costly errors, especially when operating across multiple tax jurisdiction

What does indirect tax compliance involve? 

Indirect tax compliance goes far beyond simply applying a tax rate to a transaction. It’s a continuous process that requires precision, local knowledge and coordination across teams. As tax authorities around the world become more sophisticated in their enforcement efforts, the compliance bar continues to rise. 

Here are the core responsibilities that make up an effective indirect tax compliance function: 

• Accurate tax determination: Getting tax right at the point of transaction is vital. This involves correctly identifying the applicable tax rate based on the nature of the goods or services, the jurisdictions involved, the customer type (e.g. B2B vs. B2C) and the place of supply. Mistakes can have a domino effect, leading to incorrect invoicing, underpayments or overpayments. 

• Timely and correct filings: Each country has its own schedule, format and submission process for tax returns. Ensuring returns are filed on time and accurately is non-negotiable. Errors or delays can result in penalties and increased scrutiny from tax authorities. 

• Cross-border transaction handling: For businesses operating internationally, indirect tax compliance gets more complex. You may need to register for VAT or GST in multiple countries, navigate reverse charge mechanisms and manage tax obligations for both inbound and outbound transactions. 

• Document and data retention: Tax authorities expect businesses to maintain thorough records – sometimes for up to 10 years of invoices, returns, transaction data and correspondence. This information must be easily retrievable, auditable and, increasingly, stored in a digital format. 

• Responding to audits: Indirect tax audits can be time-consuming and disruptive. Being audit-ready means having clean, consistent data, traceable transaction histories and a clear understanding of how tax decisions were made. Strong documentation and internal controls make a significant difference here. 

Who are the key parties involved in indirect tax compliance? 

Indirect tax compliance is a cross-functional and collaborative effort. Success depends on the collaboration of several key stakeholders: 

• Finance teams: Responsible for accurate bookkeeping, filings and cash flow forecasting related to tax obligations. 

• Tax professionals and advisors: Provide regulatory expertise, interpret complex rules and manage compliance risk. 

• Technology partners: Supply the solutions that automate calculation, reporting and document management, helping teams scale and adapt to changing mandates. For example, Fintua offers Comply…

As regulatory environments become more digitised and demanding, it’s no longer enough to treat indirect tax as an afterthought. Proactive, well-integrated compliance processes are essential to reduce risk and maintain operational efficiency. 

Why indirect tax compliance is so complex

Indirect tax compliance might seem like a straightforward process: calculate the right rate, file the return, pay the tax. But in practice, it’s anything but simple. Especially for businesses operating across borders or at scale. Several factors contribute to the complexity: 

1. Varying rules across jurisdictions:

No two countries handle indirect tax the same way. Even within the EU, where VAT is harmonised in principle, each member state has its own rates, exemptions, invoice formats and filing procedures. Outside the EU, the diversity widens further – consider how different GST operates in India compared to Australia, or how sales tax is managed at the state level in the U.S

2. Constantly changing rates and regulations: 

Indirect tax is a moving target. Rates change frequently – often with little notice – and new rules are regularly introduced. From Brexit-driven VAT updates to evolving digital services taxes, staying compliant requires continuous monitoring and adjustment. What was correct last quarter may already be out of date. 

3. Manual processes and siloed data 

Many finance teams still rely on spreadsheets, email chains or outdated ERP systems to manage tax processes. These manual workflows increase the risk of human error, create inefficiencies and make it difficult to ensure consistency across business units or countries. Plus, when data lives in silos, it’s hard to get a complete, accurate picture of your tax position. 

4. eInvoicing and digital reporting mandates 

Governments are increasingly adopting real-time reporting and mandatory einvoicing to combat tax evasion and close VAT gaps. These requirements differ by country and often involve technical specifications, digital signatures and integration with local tax portals. Compliance now demands not just financial accuracy but also technological agility. 

5. Risk of non-compliance 

Getting indirect tax wrong can have serious consequences: 

• Financial penalties for late or incorrect filings 

• Audits and investigations from local tax authorities 

• Blocked VAT reclaims that impact cash flow 

• Reputational damage if non-compliance becomes public 

For finance leaders, these risks translate into strategic concerns. Non-compliance isn’t just a tax issue – it can disrupt operations, damage stakeholder trust and erode competitive advantage. 

Understanding these challenges is the first step toward building a more resilient, future-ready compliance function. In the next section, we’ll look at how businesses are managing indirect tax in practice—and where there’s room to improve. 

Indirect tax compliance in practice 

Indirect tax compliance is a continuous, multi-step process that touches nearly every financial transaction a business makes. From the moment an invoice is generated to the point a tax return is submitted; accuracy and consistency are essential. 

Here’s a look at the typical workflows involved: 

1. Transactional tax calculation:

Every sale or purchase triggers a tax determination process. The business must calculate the correct VAT, GST or sales tax based on: 

• The product or service type 

• Customer location and status (e.g. B2B vs. B2C) 

• Shipping destination 

• Local tax rules and thresholds: This step often integrates with ERP, billing or e-commerce systems and errors here can cascade downstream into incorrect invoicing and reporting. 

2. Invoice validation and archiving:

Invoices must comply with local tax regulations, which may require specific fields, formats or digital signatures. Many countries also mandate long-term storage of invoices, often in a specific format (e.g. PDF/A or XML) and for a defined period (e.g. 6–10 years). eInvoicing regulations are also introducing pre-clearance or real-time transmission to tax authorities in certain jurisdictions. 

3. Periodic VAT/GST return submissions:

Businesses must compile and submit regular tax returns (monthly, quarterly or annually), often per country. These include: 

• Summary totals of taxable sales and purchases 

• Input and output tax calculations 

• Net VAT payable or reclaimable: Reconciling transactions, ensuring data integrity, and meeting country-specific filing formats can be time-intensive. 

4. Additional compliance reports 

Beyond standard returns, many jurisdictions require additional reports: 

• EC Sales Lists (for intra-EU trade) 

• SAF-T (Standard Audit File for Tax) (in XML, for digital audit purposes) 

• Intrastat declarations (for movement of goods across EU borders). These vary by jurisdiction and may need to be generated from multiple data sources. 

How businesses handle indirect tax today 

There’s no one-size-fits-all approach. Businesses typically fall into one of three models: 

• In-house management: Larger organisations often have dedicated indirect tax teams managing everything from rate determination to reporting. While this offers control, it also places a heavy burden on internal resources, especially when compliance spans multiple countries. 

• Outsourcing to advisors or shared service centres: Many companies rely on external tax advisors or regional service hubs to handle returns and reporting. This can ease the resource burden but often leads to slower turnaround times and fragmented data ownership. 

• Leveraging software solutions: Increasingly, businesses are turning to tax technology platforms that automate calculation, validate transactions in real time, generate country-specific filings and manage digital archiving. This approach reduces risk, increases efficiency and is becoming essential as governments push for digital compliance. 

In today’s tax landscape, the most effective compliance strategies often combine internal expertise, trusted partners and intelligent technology. In the next section, we’ll explore how tech is transforming indirect tax compliance and what finance teams should look for in a modern solution. 

The role of technology in streamlining compliance 

As indirect tax compliance becomes more complex and digitised, manual processes can no longer keep pace. Technology has become essential, not just to maintain compliance, but to do so efficiently, accurately and at scale. For finance professionals, understanding how to leverage the right tools is now a key part of strategic tax management. 

Benefits of using indirect tax technology  

Modern indirect tax technology offers a range of benefits that help reduce risk, save time and improve accuracy: 

• Automated tax calculation at the point of transaction, ensuring the right rates are applied in real time

Technology is no longer optional in the world of indirect tax. It’s the enabler that allows finance professionals to move from reactive firefighting to proactive, strategic compliance management. 

In the final section, we’ll explore best practices for building a high-performing indirect tax compliance function – whether you’re just starting out or ready to optimise your existing processes. 

Best practice for finance teams 

Achieving consistent, accurate indirect tax compliance doesn’t happen by chance – it requires structure, collaboration and the right tools. Whether you’re centralising your tax processes, preparing for new mandates or scaling internationally, these best practices can help your finance team stay ahead of risk and operate more efficiently. 

1. Stay up-to-date on tax rules and regulatory updates: 

Indirect tax laws change frequently and often without much notice. Finance professionals should: 

• Monitor updates from local tax authorities 

• Subscribe to industry newsletters or alerts 

• Lean on tax advisors or software providers for real-time insights 

Keeping up to date ensures your business can respond swiftly to rate changes, new filing obligations or shifts in policy (such as e-invoicing mandates or changes to VAT thresholds). 

2. Collaborate across departments: 

Indirect tax compliance isn’t just a finance responsibility. It requires input and support from: 

• Tax teams, who bring regulatory expertise 

• Legal teams, who ensure contracts and policies are compliant 

• IT teams, who enable the integration of tax technology and data flows 

Cross-functional collaboration helps avoid blind spots and ensures compliance is built into business operations from the ground up.

Standardisation creates consistency, reduces manual errors and simplifies audits. Key controls include: 

• Clear ownership of tax processes 

• Consistent procedures for tax determination, invoicing and reporting 

• Internal checklists or automated validations before filing 

Standardised workflows are especially important for businesses operating across multiple countries or entities. 

4. Conduct regular reviews and audits:

Proactive reviews help identify and correct issues before they escalate. These may include: 

• Periodic reconciliations of VAT/GST accounts 

• Internal audits of transaction accuracy 

• Post-filing reviews to catch inconsistencies 

Regular self-assessments reduce the risk of penalties, make external audits smoother, and build trust with tax authorities. 

5. Invest in the right tools and partnerships:

Modern compliance requires modern solutions. Look for tools that: 

• Automate tax calculation and return generation 

• Support country-specific requirements (e.g. SAF-T, e-invoicing, real-time reporting) 

• Integrate easily with your ERP or finance systems 

By embedding these best practices into your compliance strategy, finance teams can transform indirect tax from a source of risk into a point of control and clarity. Done right, it becomes a competitive advantage – supporting business growth, improving operational efficiency and protecting your reputation.
