Costs and strategies in GDLK for SMEs

Optimizing costs in SME linkage transactions
SMEs often face challenges in managing costs when conducting related party transactions. Important costs include:
Intercompany loans: loans between legal entities within the same business group.
Internal service costs: administration, IT, marketing, R&D, consulting, logistics, legal.
Internal sales costs: transactions of goods and services between subsidiaries or branches.
A cost optimization strategy needs to ensure that these costs are allocated appropriately, while adhering to the arm's length principle. This not only helps SMEs save money, but also reduces tax risks and improves internal transparency.
SME Transaction Structuring Strategy
SME transaction structure is the foundation for cost management and risk control:
Identify the transaction structure between SME entities such as parent company, branches and subsidiaries.
Adjust prices, interest rates and internal services according to the arm's length principle to ensure reasonable and transparent costs.
Establish internal controls and regular monitoring to minimize tax risks and avoid profit adjustments from tax authorities.
Applying a reasonable transaction structure strategy helps SMEs optimize costs, maintain financial efficiency and ensure compliance with legal regulations.
Documentation and explanation of related party transactions for SMEs

Required documents
To ensure that the GDLK service for SME solutions is transparent and complies with the law, businesses need to prepare complete documents, including:
Master File and Local File (if applicable): provide an overview of the business and related transactions, helping tax authorities properly assess business activities.
Contracts and payment documents: record internal transactions such as services, loan interest, internal sales, ensuring cost transparency.
Transfer pricing and reasonable cost documents: demonstrate that costs and service prices, interest are determined according to the arm's length principle, minimizing tax risks.
Preparing complete documents helps SMEs easily explain to tax authorities, avoiding additional collection or profit adjustment.
Internal monitoring and control
Effective records management requires close monitoring and internal controls:
Use transaction management tools and software: track service costs, interest, automatically allocate costs and generate quick reports.
Regularly review and update records: ensure all contracts, documents and reports accurately reflect the actual transaction and comply with the law.
Regular risk assessment: early detection of errors in valuation or documentation, helping SMEs proactively adjust and explain to tax authorities.
Combining comprehensive documentation with strong internal controls not only protects SMEs from tax risks but also improves cost management efficiency across the group.
Risks and notes for SMEs
In the process of applying GDLK services for SME solutions, businesses often encounter some common risks:
Incomplete or inaccurate records: Master File, Local File, contracts, and payment documents are not fully prepared, making it difficult to explain to the tax authorities.

Non-transparent cost allocation: Unsystematic cost allocation between subsidiaries, branches or SME divisions can create risks for internal audit and tax authorities.
How to minimize tax risk
Tight internal control: Establish monitoring processes and assign clear responsibilities to each department for cost management and transaction records.
Regularly update records: Ensure all contracts, documents and reports accurately reflect the actual transaction and comply with the arm's length principle.
