Value of Supply and Valuation Rules

A Lesson Context

Defining “Value of Supply”: In Zimbabwe’s VAT system, the value of supply is the amount on which VAT is calculated for any taxable transaction. In simple terms, it represents the taxable price of goods or services. Determining this value correctly is crucial because VAT is charged as a percentage of the value of supply[1]. If the value is understated or overstated, the VAT paid will be wrong, leading to compliance issues or penalties.

Importance in the Tax System: Value of supply is a foundational concept in VAT. It ensures the tax is levied on the actual economic value exchanged. For example, whether a customer pays in cash, with goods (barter), or at a discount, the law provides rules so that the VAT base reflects the true consideration. By capturing the real value, Zimbabwe’s VAT law maintains fairness and prevents tax avoidance (such as under-valuing sales to reduce VAT). It also protects consumers – laws require prices to generally be quoted VAT-inclusive, ensuring transparency about the full cost[2][3].

Scope and Relevance: This topic is fundamental for tax professionals, businesses, and advanced students. It links to many practical scenarios: giving discounts or accepting trade-ins, dealing with related-party transactions, quoting prices in advertisements, or handling refunds. Understanding the value of supply means knowing how to treat non-monetary payments, how to adjust for VAT-inclusive prices, and how to apply anti-avoidance rules for sales between connected persons (like related companies or family members). Mastery of these rules is essential to ensure the correct amount of VAT is charged, collected, and remitted to ZIMRA (Zimbabwe Revenue Authority).

Contextual Example: Suppose a Harare electronics shop sells a TV for USD 230. The value of that supply is USD 230 (the price paid). VAT at 15% would normally be USD 34.50. But if that price was advertised as “USD 230 including VAT”, the shop must back-calculate the value of supply (which would be USD 200, since USD 230 is gross of 15% VAT)[3]. This simple example shows why clarity on value is critical – it affects how much VAT the business owes.

B Legislative Framework

Primary VAT Legislation: The rules on value of supply are governed by the Value Added Tax Act [Chapter 23:12] (“VAT Act”). Section 6 of the VAT Act is the charging provision requiring VAT to be levied on the value of taxable supplies[1]. The detailed rules for determining that value are set out mainly in Section 9 of the VAT Act.

General Rule (Section 9(2)): The value of a taxable supply is the consideration paid for that supply, excluding the VAT itself[4]. If a seller doesn’t separately account for VAT in the price, the price is deemed to include VAT equal to the tax fraction[5][6].
Open Market Value (Section 3): Defines how to find the “open market value” (OMV) for transactions lacking a fair cash price. It assumes parties are unrelated and acting freely[7][8]. One can use a similar supply as a proxy[9] or a method approved by the Commissioner-General[10][11].
Consideration Wholly in Money (Section 9(3)(a)): Value of supply is the amount of money paid[12] (excluding VAT).
Consideration Partly or Wholly in Kind (Section 9(3)(b)): Value must include the OMV of the goods or services given in exchange[12]. Barter deals are taxed as if money changed hands.
Connected Persons (Section 9(4)): If a supply is made to a connected person below OMV and the purchaser cannot claim full input tax, the value is deemed to be OMV[13][14][15][16].
Deemed Supplies: For self-supply (Section 7), the value is usually the lower of cost or OMV[17][18].
Instalment Credit Agreements: Section 9(6) says the value is the “cash value” of the goods, excluding interest and finance charges[19].
Pricing Requirements (Sections 69 & 70): Prices charged are deemed VAT-inclusive[3][20][21]. Advertised prices must include VAT and state so[2][22][23]. This even applies to large tenders by unregistered persons (Section 70(2))[24].

Finance Act 2025 Updates: Effective 1 January 2026, the standard VAT rate increased from 15% to 15.5%[25]. While core valuation definitions remain, the tax fraction calculation has updated to 15.5/115.5.

C Detailed Conceptual Explanation

1. General Valuation Rule – Consideration is Key

The fundamental principle is that value of supply = consideration for the supply (excluding VAT)[4]. “Consideration” means what the supplier receives in return – typically the price paid. If a tailor sells a suit for ZWL 50,000 exclusive of VAT, the value is 50,000 and VAT is 7,500. If inclusive, the value is 43,478 (using fraction 15/115). Excluding VAT prevents “tax on tax.”

2. Wholly Monetary Consideration

If payment is entirely in money, the value is just that amount net of VAT[12]. For a fee of ZWL 1,000,000, if nothing is said, Section 69 deems it VAT-inclusive[3]. The architect would remit 130,434 in VAT, leaving 869,566 as the taxable value.

3. Consideration in Kind (Barter and Part-Payment)

Pure Barter: If a plumber fixes a baker’s oven (worth $200) for 10 cakes (worth $200), each makes a supply valued at $200. Both must account for VAT on the market value of what they provided[12][8].
Part Money, Part Goods: In a car trade-in, if a $30,000 new car is bought with $20,000 cash and a $10,000 old car, the value of supply is $30,000[12].

4. Discounts and Rebates

Point of Sale: A 20% discount reduces the consideration and thus the VAT base immediately.
Prompt Payment: Terms clearly stated on the invoice (e.g., "2% off within 7 days") allow the supplier to adjust VAT without a formal credit note if the discount is taken[26].
Retrospective Rebates: Volume-based rebates require issuing a credit note (Section 21) to adjust the originally declared value and VAT.
Deposits: Returnable container deposits include VAT[27]. Security deposits (for damages) generally do not attract VAT unless applied to a charge.

5. Connected Persons and Fair Value

Section 9(4) imposes OMV if: (a) price is below market, (b) parties are connected (relatives, common control), and (c) the buyer cannot claim full input tax[13][14][15]. This prevents abuse like selling assets cheaply to family or exempt sister companies[16].

6. VAT Inclusive vs Exclusive Pricing

Section 70 mandates that prices quoted to the public must be inclusive of VAT[2][22]. Section 69 deems any price collected as inclusive if VAT wasn't explicitly added[3][21]. Unregistered bidders in large tenders (above US$25,000) are also deemed to have quoted VAT-inclusive prices[24].

7. Case Law Insights

The courts consistently uphold the integrity of valuation rules. In Mayor Logistics, the court confirmed that neglecting to charge VAT makes the price inclusive by default[20]. Triangle Ltd reinforced that suppliers cannot retroactively charge VAT to customers after a misclassification error[21]. Mylo (Pvt) Ltd confirmed that barter transactions constitute reciprocal taxable supplies.

D Real-World Applicability

Individuals

Protected by inclusive pricing laws. Sole traders approaching the threshold must factor VAT into quotes to avoid margin erosion from Deemed Inclusive rules.

SMEs

Must ensure fiscal devices handle discounts correctly. Family businesses must avoid "handover" of assets at book value to avoid OMV-based VAT assessments.

Large Corporates

Manage complex multi-currency valuations and inter-company management fees. High-value tenders must be scrutinized for VAT clauses to protect against rate changes.

E Case Law Integration

Mayor Logistics (Pvt) Ltd v ZIMRA (2014)

The Constitutional Court upheld Section 69, confirming that any price received is deemed VAT-inclusive if tax wasn't separately charged. The burden of charging tax lies solely with the supplier[20].

Triangle Ltd & Hippo Valley Estates v ZIMRA (2021)

The Supreme Court ruled that sellers who mistakenly didn't charge VAT (thinking a supply was zero-rated) cannot later demand extra VAT from buyers. They must remit the tax from the original price[21].

Travel Agents Association v ZIMRA (2015)

Established that for intermediaries, the value of supply is the commission earned, not the gross value of the third-party ticket or service being facilitated[31].

F Common Pitfalls

Hidden VAT in Quotes

Advertising "VAT Exclusive" prices to consumers. Legally, the sticker price must include VAT, or the business might be forced to treat the lower price as the gross amount[2].

The "Freebie" Trap

Thinking that "Buy One Get One Free" or gifts escape VAT. Promotional items often trigger a deemed supply at OMV/cost if input tax was originally claimed[17].

Barter Ignorance

Assuming that because "no money changed hands," no VAT is due. Each party is making a supply and must value it at market rates[12].

Unadjusted Discounts

Granting a discount but remitting VAT based on the original full price. This results in overpaying tax to ZIMRA unnecessarily.

G Knowledge Check

Q1: Inclusive Math: A shop displays $115 (inclusive). Using a 15% rate, what is the value of supply and VAT?

Q2: Barter: A carpenter swaps a $300 table for maize worth $280. What value of supply should the carpenter use?

Q3: Connected Parties: A firm sells a $200k machine to an exempt sister company for $50k. What is the taxable value?

Q4: Misclassification: A company received $100k for sales they thought were zero-rated. How much VAT do they owe if ZIMRA rules them standard-rated?

H Quiz Answers with Explanations

Answer 1: Value = $100, VAT = $15 ($115 × 15/115).

Answer 2: $300. Value is based on the OMV of the supply provided[12].

Answer 3: $200k. Section 9(4) deems OMV because the buyer is connected and cannot claim input credit[13].

Answer 4: $13,043 ($100,000 × 15/115). Section 69 deems the receipt inclusive[21].

I Key Takeaways

OMV Default: Use Open Market Value for barter, non-money trades, and specific connected party deals[12][13].
Inclusive by Law: All prices to the public are deemed to include VAT. No "surprise" additions at payment[22][3].

Interest Excluded: For instalment credit, VAT applies only to the "cash value," not the finance charges[19].
Tender Rule: Large tender quotes by unregistered persons are now deemed to include VAT for parity[24].
Rate Change (15.5%): Update all inclusive formulas to 15.5/115.5 for 2026 transactions[25].
