VAT OSS correction – how to settle the return of goods, discount and error in VIU-DO?
You generally report the correction of previous OSS sales in your current declaration as a difference attributed to the original period and country of consumption.
You don't usually replace an old VIU-DO with a new, full declaration. First, determine whether the original sale even occurred, what happened afterward, and whether the tax base or VAT changes.
First, determine if the sale occurred
Cancellation, refund, rebate, exchange, and chargeback don't automatically lead to the same outcome. Start with three questions that separate no-sale from correction, new delivery, and uncollectibility analysis.
Cancellation, full or partial refund, discount, exchange, chargeback, rate error, card fraud, non-collection or returned to sender.
If no event giving rise to VAT has occurred, there may be no sale to report.
Before submitting your return, you correct the source data. After submitting, you need to make corrections.
Separate value adjustments from goods movement and payment operator costs.
No payment, delivery or prior tax liability.
The transaction has not yet been reported in VIU-DO.
The difference goes into the current declaration with the source data.
The replacement may include new service requiring a separate assessment.
Failure to pay is subject to the rules of the relevant country of consumption.
The document and period depend on the nature of the event
Don't conflate physical returns with automatic VAT reductions. For each event, check whether a sale occurred, whether the remuneration changed, and which period and country the difference applies to.
| Event | Was the sale made? | Is VAT changing? | Document | Period | Main risk |
|---|---|---|---|---|---|
| Cancellation without payment | Usually not if there was no delivery or prior event. | No VAT to correct. | Cancellation of order. | No entry or correction before declaration. | Automatically create sales from the order itself. |
| Advance payment and cancellation | The obligation may have arisen earlier. | Correction possible after payment refund. | Advance payment and return confirmation. | Period of original obligation. | Omission of an earlier advance payment. |
| Full or partial refund | Yes. | Usually a reduction in whole or in part. | Return, acceptance and refund. | Original sales period. | Using the current rate. |
| Discount after sale | Yes. | Reduction of base and VAT. | Discount arrangement. | Original transaction. | No association with source ID. |
| Exchange | Depends on mileage. | Possible correction and new delivery. | Exchange protocol and flow of goods. | Depending on both events. | Mechanical "return + sale". |
| Chargeback | Often yes. | Not always. | Dispute, operator decision and flow of funds. | After determining the nature of the incident. | Subtracting the operator commission from the base. |
| Uncollectibility | Yes. | According to the principles of the consumption state. | Evidence of claims and activities. | According to the law of the relevant country. | Only Polish rules apply. |
| Shipment returned to sender | Requires delivery and payment arrangements. | It does not result from the shipment status itself. | Customer tracking, acceptance and settlement. | After sales qualification. | Recognition of logistics traffic as a VAT correction. |
Refund and discount after submitting VIU-DO
A return or discount that reduces the basis results in a negative adjustment to the original transaction. Keep the original country of consumption, rate, and currency. Do not apply the current rate if it has changed since the date of sale.
The transaction goes to VIU-DO with French VAT.
A documented negative difference is created.
The correction indicates France and the original transaction data.
The technique for reporting the period and country is described in the VIU-DO guide – OSS VAT return. The European Commission confirms that corrections after the declaration deadline are reported in a subsequent return, and not by replacing the entire previous settlement.
A chargeback is not always a refund
A chargeback can result in a refund to a customer, a payment dispute, or simply a failure to receive funds by the seller. The operator's commission does not automatically reduce the sales base.
First, determine the sales impact
- whether the order has been canceled;
- whether the customer retained the goods;
- whether the seller returned the remuneration;
- whether the operator collected only its own fee;
- whether the event is uncollectible.
Don't automatically code it as two events
- may correct the original sale;
- can create a new delivery;
- can be a move without a change in salary;
- requires linking documents and goods;
- the result depends on the actual mileage.
Returning to another warehouse does not change the country of original sale
A physical return from France to a warehouse in the Czech Republic does not change the country of primary consumption of the sale. However, it may impact inventory, local VAT, and statistical obligations.
France remains the country of consumption of the corrected transaction.
The movement of goods requires separate warehouse and reporting analysis.
Each consuming country has its own balance
The correction can increase or decrease VAT. A negative amount reduces the amount due to the same country of consumption. If it exceeds its current VAT, an overpayment may occur in that country.
The current VAT due to Germany remains in the German balance.
Payment to GermanyThe negative revision of French sales remains attributable to France.
Possible overpayment in FranceThe current VAT for Italy does not take over the negative correction of France.
Payment to ItalyYou don't automatically offset a negative France with a positive Germany or Italy. The European Commission indicates that a negative balance in one country is not offset against the VAT due to another country of consumption.
The three-year period is counted from the date of the initial declaration
Standard corrections to previous declarations are reported by the OSS for three years from the date the initial declaration was due. After this date, you contact the country of consumption directly according to its rules.
Transaction covered by the OSS procedure.
The three-year window starts from this date.
You report the difference electronically in a later declaration.
You apply the principles of the proper state of consumption.
The VCU-DK form may be relevant for corrections submitted directly to Poland. It is not intended for corrections to German or French VAT. The official rules and forms are published by the Ministry of Finance on the website concerning OSS and IOSS corrections submitted directly to Poland.
Merge the correction with the original transaction
Each adjustment should include the original transaction ID, reason code, date, amount, original period, country, rate, currency, document, and physical return status. Data is retained for 10 years.
- Was the sale made?
- Has an advance payment been received?
- Original VIU-DO
- Transaction ID
- The State of Consumption
- Original VAT rate
- Original exchange rate
- Tax base
- Reason for correction
- Source document
- Refund Date
- Physical return of goods
- Operator fee
- Three-year term
- Status in the OSS procedure
- Direct correction
- Possible INTRASTAT
- Archive for 10 years
The scope of data and its storage method are further developed in the VAT OSS registration. Corrections may also be relevant after deregistration from the VAT OSS or exclusion from the procedure.
Use the original transaction data for corrections
Changing the rate in the country of consumption does not automatically change the settlement of previous sales. Apply the current rates to new transactions and calculate the adjustment according to the source data.
Returns from several countries do not match VIU-DO?
We help connect events to original transactions, distribute country balances, check the three-year deadline, and prepare data for proper settlement.

VAT OSS Correction - Questions and Answers
Generally, no. You report the correction in your current declaration, with reference to the original period and country of consumption.
Determine the original transaction, country of consumption, period, rate, and amount. Report the negative difference in a subsequent VIU-DO with reference to the original period.
No. First, determine whether the sale was canceled or refunded, or whether there was only a default or carrier fee.
The rate of the original transaction. Subsequent changes to the rate for new sales do not automatically change the previous settlement.
Not automatically. A negative balance in one country of consumption is not offset against VAT due to another country.
Typically three years from the date on which the original declaration was due.
Please contact the country of consumption directly and apply its national rules. This adjustment is no longer part of the OSS procedure.
It does not automatically change the country of consumption of the original sale. However, the movement of goods to another warehouse may create separate local and statistical obligations.
