Paragon z NIP in Poland 2026: simplified invoice up to 450 zł

In 2026 a receipt with NIP up to 450 zł gross (or 100 euro) is a simplified invoice. What it must show, VAT deduction, KPiR and KSeF changes from 2027.

When you buy something for your business, give your NIP (tax identification number) before the receipt is printed. A receipt showing the buyer's NIP for up to 450 zł gross (or 100 euro if the amount is in euro) that meets the requirements of the VAT Act is a simplified invoice. The duty to give your NIP before the sale is completed at the till has applied since 2020, not just since 2026.

We explain what a simplified invoice is (Art. 106e ust. 5 pkt 3 of the VAT Act), when a receipt with NIP replaces an invoice, how to deduct VAT and what changes from 2027 under KSeF, the national e-invoicing system.

Law checked on: 18 September 2026. The article mainly covers domestic business purchases.

What is a simplified invoice

A simplified invoice may leave out some of the data required on a standard invoice. Under Art. 106e ust. 5 pkt 3 of the VAT Act, it may omit the buyer's name and address, as well as the data listed in ust. 1 pkt 8, 9 and 11–14. The buyer's NIP is still required. The simplification applies provided that:

the total amount due (gross) does not exceed 450 zł or 100 euro (if the amount is expressed in euro),
it contains data from which the tax amount for each VAT rate can be determined.

Above 450 zł (or 100 euro) you cannot issue a simplified invoice — a full VAT invoice is needed.

The limit alone is not enough. Art. 106e ust. 6 rules out the simplification for, among others, intra-Community supplies of goods (WDT), intra-Community distance sales of goods and sales without the buyer's NIP.[2]

What a simplified invoice must contain

The document must show at least:

the date of issue,
the date of delivery, completion of the service or receipt of payment, if it is specified and differs from the date of issue,
a sequential number,
the seller's details (name and address, NIP),
the buyer's NIP,
the name of the goods or service,
the total amount due (gross),
data from which the tax amount for each VAT rate can be determined.

The buyer's name and address can be left out, but not the buyer's NIP. The document must also make it possible to determine the tax amount for each VAT rate.

A receipt with NIP as a simplified invoice

A fiscal receipt showing the buyer's NIP whose total amount due does not exceed 450 zł (or 100 euro) is treated as a simplified invoice. The receipt number doubles as the invoice number.

This means such a receipt:

is a basis for deducting VAT (if the purchase relates to taxable activity),
is an accounting document in the KPiR, the tax revenue and expense book (in the column for the type of expense),
cannot have a separate invoice issued for it.

How to get your NIP on a receipt

Most cash registers and POS systems let the buyer's NIP be added before the transaction is finalised. You can:

give your NIP before paying (systems that support NIP),
use a loyalty card linked to your NIP (in some chains),
ask the cashier to add your NIP.

Without the buyer's NIP, an ordinary fiscal receipt is not a simplified invoice. Whether the expense can be documented for the KPiR under one of the special rules described below is a separate question.[2][3]

Receipt without NIP — can it be booked?

An ordinary shop receipt without the buyer's NIP does not give a right to deduct VAT as a simplified invoice. That does not mean every document without a NIP rules out a cost for PIT. The KPiR regulation provides for special evidence for some expenses.[2][3]

You cannot fix a missing NIP on a receipt already issued by asking for an invoice with your NIP afterwards. According to the Ministry of Finance (MF), the seller may then issue a consumer invoice, without the buyer's NIP. So tell the seller that the purchase is for your business and that you need an invoice before the sale is completed at the till. If the receipt exceeds the simplified-invoice limit, give your NIP for the receipt and ask for a full invoice.

KPiR exceptions and a proper bill

The regulation in force since 1 January 2026 allows, among other things, fuel or oils bought abroad to be documented with a receipt or cash slip (§ 8 ust. 4). The document must show the date, the seller, the quantity, the unit price and the purchase value. On the back you must write your business details, address and the type of purchase. A parking-meter ticket, in turn, can be attached to an internal document (§ 8 ust. 2 pkt 8). These exceptions concern documenting the cost, not an automatic VAT deduction.[3]

A properly issued bill (rachunek) is an accounting document under § 6 ust. 3 pkt 1 of the regulation. There is, however, no general rule that any "purchase note" can stand in for a missing invoice on a small expense. Internal documents are allowed only in the cases listed in the regulation. Art. 22 ust. 6b of the PIT Act sets the date on which a cost is incurred, but it does not by itself turn every receipt into an accounting document.[3][4]

VAT deduction from a simplified invoice

A receipt with NIP (as a simplified invoice) gives a right to deduct VAT under the general rules (Art. 86 ust. 1 of the VAT Act):

the purchase must relate to taxable activities,
the VAT is shown on the document or can be calculated from it,
the buyer is an active VAT payer.

On the buyer's side, a simplified invoice goes into the purchase records of the JPK_V7 file under the general rules. A correct document does not lift the statutory exclusions from deduction, e.g. for some accommodation and catering services (Art. 88 of the VAT Act).[2]

Example

You buy fuel in Poland for 300 zł gross (243,90 zł net + 56,10 zł VAT at 23%) for a passenger car that is a fixed asset of the business and is also used privately. We assume an active VAT payer entitled to deduct 50% of the VAT who records costs in the KPiR. A receipt with NIP that meets the simplified-invoice requirements:

is a simplified invoice (amount ≤ 450 zł),
VAT 56,10 zł — you deduct 50% = 28,05 zł (car in mixed use, Art. 86a),
the PIT cost is 75% of the net amount plus the non-deductible VAT: (243,90 zł + 28,05 zł) × 75% = 203,96 zł (Art. 23 ust. 1 pkt 46a and ust. 5a of the PIT Act).[4]

Don't apply this example to every car. For a private car owned by the business owner that is not a business asset, Art. 23 ust. 1 pkt 46 sets a separate cost limit: 20%.[4]

What KSeF changes from 2027

The transition period under Art. 145n of the VAT Act ends on 31 December 2026. From 1 January 2027:

according to MF answer no. 17, a fiscal receipt with the buyer's NIP can still be issued, but it will not be a simplified invoice,[5]
for a typical business purchase you need to make sure you get an invoice, as a rule issued in KSeF, subject to the statutory exclusions; it can be a full invoice or a simplified one if it meets the conditions,[2][6]
the FA(3) schema allows a simplified invoice up to 450 zł (100 euro) to be issued without the buyer's name and address, but not without the buyer's NIP.[6]

Don't conclude from this that any invoice issued outside KSeF automatically takes away the buyer's right to deduct VAT. In answer no. 7 the MF confirms that right as a rule and stresses due diligence. The separate rules for documenting certain costs in the KPiR also have to be assessed on their own.[3][5]

In 2026 a receipt with NIP up to 450 zł is still a simplified invoice. More about e-invoicing in our complete KSeF guide.

Pitfalls

Receipt with NIP above 450 zł — it is not a simplified invoice. You need to ask for a full VAT invoice.
No NIP on the receipt — give it before the sale is completed at the till. Don't assume it can be added later.
Double documentation — if you have a receipt with NIP (a simplified invoice), no separate invoice may be issued for the same transaction.
Deduction timing — for an ordinary domestic purchase, the right to deduct arises once the tax obligation arises, but not earlier than in the period in which you receive the invoice. If you don't use it straight away, you can deduct the VAT in one of the next three monthly periods or the next two quarterly periods (Art. 86 ust. 10, 10b pkt 1 and 11).[2]
Passenger car — the VAT and PIT cost limits are separate. Check how the car is used and whether it is a business asset instead of automatically booking the whole receipt amount as a cost.[2][4]

FAQ

Is every receipt with NIP a simplified invoice?

Not every one. In 2026 the amount must be at most 450 zł gross, or 100 euro if the amount due is in euro. The document must show the buyer's NIP and the other required data, including data from which the VAT for each rate can be determined. The simplification does not cover transactions excluded in Art. 106e ust. 6, such as WDT.[2]

Can I deduct VAT from a receipt without NIP?

Not from an ordinary shop receipt without the buyer's NIP: it is not a simplified invoice. Don't confuse it with documents treated as invoices under separate provisions. Being able to document some expenses in the KPiR without a NIP does not mean you have a right to deduct VAT.[2][3]

Can a simplified invoice be issued in KSeF?

Yes. The FA(3) schema supports simplified invoices up to 450 zł or 100 euro, marked "UPR". The buyer's name and address can be left out, but not the buyer's NIP. However, the MF manual from February 2026 notes that the KSeF Taxpayer Application (Aplikacja Podatnika KSeF) does not offer this type of invoice. Check whether the software you use does.[6]

Does a receipt with NIP above 450 zł allow a VAT deduction?

The receipt alone is not enough. The 450 zł limit (or 100 euro for amounts in euro) applies to the whole gross amount due, not to a single item. Above it, ask the seller for a full invoice for the receipt with NIP. You then assess the right to deduct based on the invoice and the general VAT rules.[1][2]

After getting a receipt without NIP, can I ask for an invoice for my business?

As a rule, you won't get an invoice with your NIP that way. The MF explains that if the NIP was not given by the time the receipt was issued, the seller may issue a consumer invoice, without the NIP. Next time, give your NIP before the sale is completed at the till. Art. 106b ust. 7 contains a special exception for passenger taxi services.[1][2]

Is a bill without a fiscal receipt a cost in the KPiR?

It can document a cost if it was issued in line with the relevant rules and the expense meets the conditions for a tax-deductible cost. The basis is § 6 ust. 3 pkt 1 of the KPiR regulation. Simply calling a slip of paper a "bill" or writing a note is not enough.[3][4]

Do I need to send a receipt with NIP to my accountant?

Yes, if you want the purchase accounted for, pass it to whoever keeps your books in line with your agreed document flow. In 2026 a receipt that is a simplified invoice can be issued outside KSeF, so don't assume your accountant will find it in the system. Check that the number, date, amounts and NIP are legible.[2]

If my business name is missing, does the receipt with NIP need correcting?

No, if the document meets the conditions for a simplified invoice. The buyer's name and address may be left out. Check above all your NIP, that the amount is within the limit and that the VAT for each rate can be determined.[1][2]

Can a receipt without NIP document a cost in the KPiR?

It is not a universal proof of cost, but the rules provide for exceptions. Fuel or oils bought abroad can be documented with a receipt meeting the conditions of § 8 ust. 4 of the regulation, once the details on the back are filled in. A parking-meter ticket can be attached to an internal document. Don't extend these exceptions to every shop purchase.[3]

Is exactly 450 zł gross within the limit?

Yes. The provision says "does not exceed", so 450 zł gross is within the limit, while 450,01 zł is not. For amounts due in euro, the threshold is 100 euro. The limit applies to the whole invoice, not to the net value or a single item.[2]

What changes for receipts with NIP from 1 January 2027?

According to the MF, they can still be issued, but they will no longer be simplified invoices. For business purchases, make sure you get an invoice, as a rule in KSeF, subject to the exclusions. The simplified invoice as a document type does not disappear: the FA(3) schema provides for it in KSeF too.[2][5][6]
