Compliant printed fields — not legal or tax advice

This builder produces the statutory printed fields for a IN document; verify the specifics with your accountant. In India, a GST tax invoice above the e-invoicing turnover threshold must also be registered on the IRP (Invoice Registration Portal) to obtain an IRN and QR code — this tool does not generate those.
Methodology

How the invoice total and tax are calculated

Every invoice total is subtotal + tax + shipping, where the subtotal is the sum of each line's quantity × unit price. What changes by country is how the tax is computed and shown: India splits GST into CGST + SGST (intra-state) or a single IGST (inter-state); the UK charges VAT per rate (20% / 5% / 0%); the US applies sales tax at the destination rate. The generator computes the split and lays it out in the compliant format for the chosen geo.

India — GST

CGST + SGST, or IGST

intra: CGST = SGST = rate/2

inter: IGST = full rate

  • Place of supply decides the split
  • Total tax is identical either way
  • HSN/SAC + place-of-supply shown

UK — VAT

Breakdown by rate

VAT = Σ (net × rate)

  • Standard 20%, reduced 5%, zero 0%
  • VAT shown as a breakdown by rate
  • Simplified invoice allowed ≤ £250

US — sales tax

Destination rate

tax = subtotal × sales-tax rate

  • Single line tax at the applicable rate
  • Plain invoice — no VAT/GST fields
  • Also: estimate, quote, receipt, PO

  1. 1
    Intra-state supply (same State) → CGST + SGST: ₹50,000 taxable at 18% GST splits equally: CGST ₹50,000 × 9% = ₹4,500 and SGST ₹50,000 × 9% = ₹4,500. Total tax ₹9,000 → invoice total ₹59,000.
  2. 2
    Inter-state supply (different States) → IGST: The same ₹50,000 at 18% is charged as a single IGST ₹50,000 × 18% = ₹9,000. Invoice total is still ₹59,000 — the tax amount is identical; only the split (one line vs two) differs.
  3. 3
    Add shipping / other charges last: Shipping and other charges are added to the taxable value (or as a separate line, per your GST treatment) before the total. The headline is always subtotal + tax + shipping.
India · Rule 46

India GST tax invoice — the mandatory fields

A GST tax invoice under Rule 46 of the CGST Rules must carry a fixed set of fields for the buyer to claim input tax credit. Miss one and the invoice is defective. This generator emits every printed Rule-46 field below.

Supplier & invoice identity

Who is billing, and the number

  • Supplier name, address & GSTIN
  • Consecutive serial number, unique for the FY (≤ 16 characters)
  • Date of issue
  • Signature / digital signature of supplier or authorised representative

Buyer, supply & tax

What is supplied, and the split

  • Buyer name, address & GSTIN (if registered)
  • Place of supply + State code (inter-state)
  • HSN / SAC code; description; quantity & unit
  • Taxable value & rate
  • CGST / SGST or IGST amounts; total; reverse-charge flag

The CGST/SGST vs IGST rule

The split is decided by the place of supply, not by where the buyer is registered. Intra-state supplies carry two lines — CGST and SGST/UTGST, each at half the rate. Inter-state supplies (and exports/imports) carry a single IGST line at the full rate. The generator switches the layout automatically from the place of supply you enter.

E-invoicing caveat — this is not an IRN/QR registration

Above the GST e-invoicing turnover threshold, a B2B invoice must also be registered on the Government Invoice Registration Portal (IRP), which returns an IRN (Invoice Reference Number) and a signed QR code that must be printed on the invoice. This stateless generator emits the printed Rule-46 fields only — it does not connect to the IRP and does not produce a registered IRN or QR. If you are within the e-invoicing mandate, generate the IRN/QR through your e-invoicing software and add it.
UK · HMRC

UK VAT invoice — the field set HMRC requires

A full VAT invoice lets a VAT-registered customer reclaim the input VAT — so HMRC prescribes exactly what it must show. A missing field means the customer can't reclaim their input VAT.

Identity & dates

Seller, customer, numbering

  • Unique sequential invoice number
  • Seller business name, address & VAT registration number
  • Invoice date + tax-point (time of supply) if different
  • Customer name & address

Lines & VAT breakdown

Net, rate, VAT by rate

  • Description of goods / services
  • Per line: quantity, unit price ex-VAT, rate, net total
  • Total excluding VAT
  • VAT breakdown by rate — 20% / 5% / 0%
  • Total including VAT

Simplified VAT invoice — retail ≤ £250

For retail supplies of £250 or less, a simplified VAT invoice is allowed: it can omit some customer details and show the total including VAT with the VAT rate per line, rather than a full net/VAT breakdown. Above £250, use the full VAT invoice field set above.
FAQ

Frequently asked questions

Under Rule 46 of the CGST Rules, a tax invoice must show: the supplier's name, address and GSTIN; a consecutive serial number unique for the financial year (up to 16 characters); the date of issue; the recipient's name, address and GSTIN (if registered); the place of supply with the State code for inter-state supplies; the HSN code (for goods) or SAC (for services); a description of the goods or services; quantity and unit; the taxable value; the tax rate; the amount of tax charged split into CGST and SGST/UTGST (intra-state) or IGST (inter-state); whether tax is payable on reverse charge; and the signature or digital signature of the supplier or an authorised representative. This generator emits all of these printed Rule-46 fields.

It depends on the place of supply. Intra-state (same State) → the rate splits equally into CGST + SGST/UTGST (18% → 9% + 9%). Inter-state (different States, or export/import) → a single IGST at the full rate (18%). On ₹50,000 @ 18%: intra-state = CGST ₹4,500 + SGST ₹4,500; inter-state = IGST ₹9,000 — both a ₹59,000 total, only the split differs.

HMRC requires a full VAT invoice to show: a unique sequential invoice number; the seller's business name, address and VAT registration number; the invoice date and the tax point (time of supply) if different; the customer's name and address; a description of the goods or services; for each line the quantity, unit price excluding VAT, the VAT rate applied and the total excluding VAT; the total amount excluding VAT; the total VAT payable shown as a breakdown by rate (20% standard, 5% reduced, 0% zero-rated); and the total amount including VAT. A simplified VAT invoice is allowed for retail supplies of £250 or less and can omit some customer details. If a required field is missing, your customer may be unable to reclaim the input VAT.

Yes — it is free with no sign-up and no login. The invoice is built and rendered in your browser and downloaded as a PDF; your business and customer details are not sent to a server or stored by us. That client-side, privacy-first design is the point: you can generate a GST tax invoice, a UK VAT invoice, a plain US invoice, or an estimate, quote, receipt or purchase order without creating an account.

No. This is a stateless, printed-invoice generator. Businesses above the GST e-invoicing turnover threshold must additionally register each B2B invoice on the Government Invoice Registration Portal (IRP), which returns an Invoice Reference Number (IRN) and a signed QR code that must be printed on the invoice. This tool produces the Rule-46 printed fields only — it does not connect to the IRP and does not generate an IRN or QR code. If you are within the e-invoicing mandate, generate the IRN/QR through your e-invoicing software or the IRP and add it to the invoice.

Methodology: invoice total = subtotal + tax + shipping. India — intra-state supply splits GST into CGST + SGST/UTGST (each half the rate); inter-state charges a single IGST at the full rate; the same total either way (₹50,000 @ 18% → CGST ₹4,500 + SGST ₹4,500, or IGST ₹9,000, both ₹59,000). Mandatory GST tax-invoice fields per Rule 46 of the CGST Rules. UK — VAT shown as a breakdown by rate (20% / 5% / 0%) per HMRC; simplified invoice allowed for retail supplies ≤ £250. The generator emits printed compliant fields only — for GST e-invoicing it does not register an IRN/QR on the IRP. Not legal or tax advice.
