Corrective Invoice Template

A corrective invoice (also called a correction invoice or invoice correction) is a document a supplier issues to fix an invoice that has already gone to the customer: a wrong quantity, price or tax rate, a missing or wrong customer detail, or the wrong date of supply. The original invoice is never edited or deleted. The correction gets its own number and date, refers clearly to the original invoice number and date, says what was wrong and shows the original value, the corrected value and the difference. In EU VAT law a document that amends an invoice and refers to it specifically and unambiguously is itself treated as an invoice. Where the term is not used, the same job is done by a credit note (to reduce what was charged), a debit note or supplementary invoice (to increase it), or by cancelling the original and issuing a replacement. Use this template when your customer, accountant or tax rules expect a single document labelled as a correction. The download is an editable HTML file with fields for the original invoice reference, the reason, the corrected lines and the amount now due or to be credited; fill it in your browser, then print it or save it as PDF.

Recommended Payment Terms

A correction does not restart the payment clock unless you and the customer agree that it does. If the original invoice was unpaid and the correction lowers the amount, keep the original due date and ask for the corrected total. If the correction raises the amount, give a fresh due date for the extra amount only, because the customer could not have paid what was never invoiced. If the customer has already paid the original amount and the correction reduces it, state on the correction whether the difference will be refunded or deducted from the next invoice, and by when. Put the original invoice number in the payment reference so the customer's accounts team can match the payment to both documents.

Tax Information

Tax rules decide which correction document you may use. In the EU, Article 219 of the VAT Directive (2006/112/EC) treats any document that amends an initial invoice and refers to it specifically and unambiguously as an invoice, so the correction must carry the same kind of details as an invoice. Germany's VAT implementing regulation (UStDV section 31(5)) allows an invoice to be corrected when required details are missing or wrong, and only the missing or wrong details need to be sent, in a document specifically and unambiguously linked to the original. In Poland, invoices issued in the national e-invoicing system KSeF cannot be edited once accepted; the Ministry of Finance's KSeF guidance says errors are corrected with a corrective invoice (faktura korygująca) issued through KSeF, and an invoice sent to the wrong buyer tax number is corrected to zero and reissued to the right buyer. In the UK, HMRC's VAT Notice 700 has no separate corrective invoice: paragraph 19.8 says that if you charged too much VAT you must account for the higher amount unless you correct the error with your customer by issuing a credit note, and if you charged too little you must account for the correct amount, for example by issuing a supplementary invoice, and paragraph 18.2.3 lists what a valid credit note shows. In the United States there is no federal invoice-correction format; businesses usually issue a credit memo and a revised invoice. This is general information, not legal or tax advice. Check the current rules with your tax authority or an adviser. Last reviewed: October 2026.

Industry context (2026)

Most of the rules behind corrective invoices come from VAT systems, not from commercial practice. The EU VAT Directive (Council Directive 2006/112/EC, Article 219) is the reason a correction must refer specifically and unambiguously to the invoice it amends: once it does, it counts as an invoice. Countries name and format the document differently. German law allows a correction that sends only the missing or wrong details (UStDV section 31(5)); German practice also uses a cancellation invoice (Stornorechnung) followed by a new invoice. In Poland the corrective invoice moved into the national e-invoicing system: according to the Ministry of Finance's KSeF guidance, KSeF became mandatory on 1 February 2026 for the largest businesses and on 1 April 2026 for the rest, with limited relief for the smallest until the end of 2026, and an invoice accepted by KSeF cannot be changed, only corrected. The UK's VAT Notice 700 (updated 25 June 2026) works with credit notes and supplementary invoices instead. In the United States, where there is no federal VAT, correction is a bookkeeping practice: the usual approach is a credit memo plus a revised invoice, with any state sales tax adjusted under that state's rules.

Worked example

Worked example (illustrative figures, 19% VAT used as the example rate). On 2 October 2026 a web developer issues invoice INV-0218 to a German client for 40 hours at €85.00: net €3,400.00, VAT €646.00, total €4,046.00. The client points out that the agreed timesheet showed 36 hours, not 40. The invoice has not been paid. On 9 October the developer issues corrective invoice INV-0223, headed 'Corrective invoice: corrects INV-0218 of 2 October 2026'. Reason: hours billed did not match the approved timesheet. Line 1, original: 40 hours × €85.00 = €3,400.00. Line 1, corrected: 36 hours × €85.00 = €3,060.00. Difference: net −€340.00, VAT −€64.60 (19% of €340.00), total −€404.60. Corrected totals: net €3,060.00, VAT €581.40, total €3,641.40, which is €4,046.00 − €404.60. The amount now due is €3,641.40, still by the original due date. If the client had already paid €4,046.00, the same document would instead say '€404.60 to be refunded by 23 October 2026' or 'to be deducted from the next invoice'. A second scenario: the amounts were right but the client's VAT number was missing. Where the rules allow it, as Germany's section 31(5) UStDV does, the correction only needs to state the missing VAT number and refer to INV-0218; no amounts change.

Common mistakes to avoid

Overwriting the original invoice

Changing the amounts on an invoice the customer already has, and sending it again under the same number, leaves two different documents with one number. Keep the original as issued and correct it with a separate document.

No clear link to the original

A correction that says 'revised invoice' without the original number and date cannot be matched to anything. EU rules require the reference to be specific and unambiguous; quote both the number and the date.

Showing only the new total

If the correction shows €3,641.40 with no breakdown, the customer has to work out what changed. Show the original line, the corrected line and the difference, including the tax on the difference.

Using a correction where a credit note is required

In the UK an overcharge of VAT is corrected with a credit note that meets HMRC's requirements, not with a document labelled 'corrective invoice'. Use the document your tax authority expects.

Sending a PDF correction in an e-invoicing country

Where the original was issued through a mandatory e-invoicing system, such as KSeF in Poland, the correction must be issued through the same system. This template is a reference layout only in those cases.

Invoicing Tips

  • 1Never edit or delete an invoice the customer already has. Leave it in your records and issue a separate, numbered correction that points back to it.
  • 2Quote the original invoice number and issue date at the top, for example 'Corrects invoice INV-0218 of 2 October 2026', so both sides can link the documents.
  • 3Show three numbers for every line you change: what was charged, what should have been charged and the difference. A correction that shows only the new total leaves the customer to reconstruct the change.
  • 4Correct the tax on the difference at the rate that applied to the original supply, not today's rate, unless your tax authority says otherwise.
  • 5If the only problem is a missing or wrong detail, such as the customer's address or VAT number, and the amounts are right, the correction can list just that detail where your rules allow it. You do not have to repeat every line.
  • 6In e-invoicing countries such as Poland, the correction has to go through the same official system as the original invoice. A PDF correction sent by email does not replace that.
  • 7If you find several errors on one invoice, fix them all in one correction rather than issuing a string of partial corrections.

Frequently Asked Questions

What is a corrective invoice?

A corrective invoice is a document a supplier issues to amend an invoice that has already been issued. It has its own number and date, refers to the original invoice by number and date, explains what was wrong and shows the corrected values and the difference. The original invoice stays in both parties' records.

Is a corrective invoice the same as a credit note?

They overlap. A credit note only reduces an amount already invoiced. A corrective invoice can reduce it, increase it or fix a detail with no change in amount, such as a wrong address. In the UK there is no separate corrective invoice: HMRC expects a credit note for an overcharge and a supplementary invoice or similar document for an undercharge. In Poland, the corrective invoice (faktura korygująca) is the standard document for both.

When should I issue a corrective invoice instead of a new invoice?

Issue a correction when the customer already has the original and may have recorded it, paid it or used it for a tax claim. If the invoice never left your business, or was an unpaid mistake such as a duplicate or the wrong client, voiding it and issuing a fresh invoice is usually simpler. Where tax law prescribes the method, follow it.

Does a corrective invoice need its own invoice number?

Yes. Give it its own number, either from your normal invoice sequence or a separate series for corrections, and never reuse the original number. It must also quote the original invoice number so the link between the two is unambiguous.

Can I just edit the invoice and send it again?

Only if the customer never received it. Once an invoice has been sent, two different documents with the same number create confusion and, for VAT-registered businesses, a record that does not match what the customer holds. Issue a correction or a credit note and a new invoice instead.

What happens to VAT when an invoice is corrected?

The tax on the difference is adjusted. If the correction reduces the price, the supplier's output tax and the customer's deductible input tax go down by the same amount; if it increases the price, both go up. Which tax period the adjustment belongs to depends on the country and on whether the original invoice was an error, so check the local rules.

Can InvoiceQuickly create a corrective invoice?

Not as a separate document type. In InvoiceQuickly you can edit an invoice only while it is a draft. For an unpaid invoice you can void it, duplicate it, fix the copy and send it with a new number, noting 'Replaces INV-0218' in the notes. On Pro you can issue a credit note against a sent invoice to reduce its balance. To bill an undercharge, create a new invoice for the difference. InvoiceQuickly copies saved business and client tax IDs to new invoice PDFs on the PDF and does not submit invoices to KSeF or any other e-invoicing system.
