Discounts are a regular part of business in Germany. They don’t just influence purchase decisions; they also directly impact value-added tax (VAT), invoicing, and accounting. Correctly indicating discounts on invoices is, therefore, central to complying with regulations.

In this article, you will learn what a discount is and what types there are. We’ll also explain how to handle VAT on discounts and the legal requirements for invoicing.

What is a discount?

In a business context, a discount is a deduction from the originally agreed sales price for a product or service that the seller applies. It is one aspect of a company’s pricing policy and encompasses all reductions of a list or offer price. Businesses in Germany can provide discounts both before and after a contract is concluded. It is an umbrella term covering a wide range of specific pricing adjustments.

Reasons for discounts

There are several different reasons why businesses use discounts:

• Increasing sales: Reduced prices can often speed up purchase decisions and increase demand.
  
• Customer loyalty: Cost advantages encourage repeat purchases and consolidate long-term business relationships.
  
• Price differentiation: Differentiating prices allows businesses to appeal directly to different customer groups, regions, or times.
  
• Competitiveness: Discounts help businesses react to competitor offers and secure market share.
  
• Price reduction under warranty: A defect in a service or product could prompt a fee adjustment. In this case, instead of encouraging an increase in sales, the discount constitutes a legally justified adjustment of the purchase price.
  

Types of discount

The term “discount” refers to various kinds of pricing adjustments that differ in their reasons, timing, and purposes. Below are the most important types:

• Sales discount
  A sales discount is a direct reduction of the regular selling price, given as either a percentage or a fixed amount. It can extend broadly, such as during a seasonal campaign, or target certain customer groups. It is often used as a volume discount, where a larger offtake results in more favorable conditions. There are also time-based sales discounts, such as early-bird and loyalty offers that honor long-term business relationships.

• Cash discount
  A cash discount is a deduction granted in exchange for prompt payment. If the payer completes settlement on the invoice by a specified deadline, the total due decreases. The aim is to speed up payment and improve the business’s liquidity.

• Bonus
  A bonus is typically awarded after the fact and often linked to conditions, such as meeting revenue targets or signing up for a rewards program. It does not lower the upfront cost; instead, it provides a later adjustment that lowers the final sum paid.

• Offer price
  An offer price is a special rate that differs from the standard sales price and is usually valid for a limited time. It is often used in marketing campaigns to increase consumer awareness and generate short-term purchase incentives.

Handling VAT on discounts

Discounts fall into categories not just by type but also by function and timing. This distinction is particularly important with respect to VAT, as the requirements for invoicing, documentation, and taxation differ.

Immediate and conditional discounts

The first distinction to make is between immediate and conditional discounts. Upfront adjustments take effect at purchase, and the offer or invoice incorporates them. In this case, tax applies to the adjusted price from the start.

Conditional incentives, by contrast, activate after specific criteria kick in. A common case involves cash discounts for timely settlement, or a bonus triggered after reaching a set revenue threshold.

While immediate discounts directly affect the invoice total, conditional discounts are not initially factored in and are recorded retroactively as price cuts once the related condition is satisfied.

Discounts before and after invoicing

Another key distinction is the timing of the discount. Markdowns granted before or at the time of invoicing, such as classic sales discounts or offer prices, are shown directly on the invoice. They reduce the original sales price at the actual moment of billing.

With post-invoicing incentives, such as cash discounts or deferred bonuses, a later adjustment modifies the fee already paid. In these cases, the original invoice requires correction, or a credit note documents the updated pricing properly.

Impact on net price and VAT

Discounts directly affect tax assessments. In principle, businesses in Germany must always charge VAT on the actual price paid (net amount). As such, discounts lower the total subject to VAT.

In concrete terms:

• With immediate discounts, VAT is charged directly on the reduced net price
  
• With retroactive discounts, revise the VAT amount initially calculated to reflect the change
  

Invoicing and legal requirements around discounts in Germany

Handling discounts correctly involves more than just calculating VAT appropriately. It also affects proper invoicing and documentation. German fiscal law provides detailed regulations on these matters, which businesses must comply with to avoid tax risks.

Legal basis

The main regulations governing the invoicing of offer prices, bonuses, and other incentives are Sections 14 and 17 of the German VAT Act (UStG). Section 14 of the UStG stipulates the mandatory information that an invoice must contain. This includes clearly and comprehensively indicating any discounts.

Section 17 of the UStG sets out how German businesses proceed when the initially agreed price changes retroactively. In these cases, they adjust any VAT already charged. The original net figure drops, they recompute the VAT due on that figure, and the difference is then adjusted to reflect the change. This adjustment must be recorded on the business’s accounts and factored in on the relevant preliminary VAT return submitted to the tax office. In practice, businesses do this by issuing a credit note or a corrected invoice, which shows both the reduced total and the amended VAT figure.

This change also has implications for the other party. The buyer must also fix their original input VAT deduction if they receive an economic benefit from the pricing update. If another company in the supply chain enjoys this benefit, then it is that company that is obligated to make the corresponding corrections. Generally speaking, this is contingent on the underlying revenue being taxable domestically.

Line-item vs. invoice discounts

A common issue for businesses in Germany is how to show markdowns and other price reductions on their invoices, specifically. They must differentiate between discounts used for line items and discounts applied to an entire invoice.

• Line-item discounts: Place the discount directly under the relevant entry, showing how the amount for that individual performance decreases.

• Invoice discounts: Apply the discount to the total at the end of the invoice.

Both options remain acceptable as long as VAT calculations stay accurate and transparent, and the taxed total remains identifiable at all times.

GoBD-compliant documentation

In addition to VAT regulations, businesses in Germany must also observe the “principles for the proper management and storage of books, records and documents in electronic form” (GoBD). Key principles include the following:

• All transactions must be traceable and verifiable.
  
• All transactions must be documented and archived truthfully using receipts.
  
• Ensuring invoices remain tamperproof and log every correction consistently.
  
• Maintaining complete documentation for any changes in pricing and discounts.
  

Indicating discounts on invoices

Businesses in Germany must clearly and comprehensibly indicate discounts on their invoices and comply with applicable laws. This applies to both line-item and invoice discounts, as well as to retroactive price reductions. Businesses issuing invoices with a discount must apply it correctly to remain compliant.

Line-item discount

Place a line-item discount directly under the relevant entry on the invoice, showing the amount for that. Each discounted item must include a clear net amount, the value of the corresponding discount, and the correct VAT figure.

Here’s an example:

• Item: 10 articles @ €50 = €500 net
  
• Line-item discount: 10% on this item = -€50
  
• Net amount after discount: €450
  
• 19% VAT on €450: €85.50
  
• Item total: €535.50
  

Global discount

A global discount applies to the total at the end of the invoice. Here, businesses charge VAT on the reduced total.

Here’s an example:

• Subtotal: €1,000
  
• Global discount 10%: -€100
  
• Net amount after discount: €900
  
• 19% VAT on €900: €171
  
• Final invoice total: €1,071
  

Indicating cash discounts

State any cash discount explicitly on the invoice. The amount of the adjustment does not have to be broken down separately for the gross/net figures plus VAT. Businesses need to indicate the following information clearly:

• Cash discount rate (e.g., 2%)
  
• Deadline for cash discount (e.g., within 10 days)
  
• Regular payment terms without cash discount (e.g., 30 days)
  

A note on the invoice could read: “Cash discount of 2% for payment within 10 days of receipt of invoice. Invoice total due in full within 30 days.”

How Stripe Invoicing can help

Stripe Invoicing helps businesses in Germany apply discounts accurately and compliantly on their invoices. Markdowns on line items and global invoice discounts can be applied automatically, and VAT is adjusted consistently. Businesses are able to generate, adjust, and send every discount invoice with confidence and in compliance with the requirements of the UStG and the GoBD.

Invoicing also provides more than 100 payment methods, 135 currencies, and 25 languages. The system automatically tracks status, enabling timely reminders and processing refunds accordingly. Businesses can integrate Invoicing easily into their existing accounting or enterprise resource planning (ERP) systems.

Frequent misunderstandings around discounts and discount invoices

Discounts on invoices can create uncertainty for many businesses, leading to frequent misunderstandings about how to handle taxes and apply sales and cash discounts correctly. Below, we summarize the most common errors and explain how to handle them properly.

Discounts have no impact on VAT

A common mistake is assuming that discounts or other price deductions do not impact VAT. However, adjustments do in fact reduce the basis of assessment for VAT. Line-item and global invoice discounts both reduce the net amount used to calculate VAT. Businesses need to always show VAT based on the actual fee.

Cash discounts can be offered without a separate note

Some businesses assume that cash discounts apply automatically. In practice, state any cash discounts explicitly on an invoice. Failure to indicate the cash discount rate, deadline, and regular settlement terms might create legal issues around amending VAT later.

Invoices do not have to be adjusted for retroactive bonuses

Another incorrect assumption is that original invoices do not need to be adjusted for retroactive bonus payments or similar price reductions. Instead, correct the document or issue a credit note whenever a retroactive bonus is applied, reflecting the reduced amount and the related VAT, while preserving traceability for accounting and the tax office.
