How should a new business partner be checked before signing a contract?

A cheap offer may have a sham company behind it. Such a partner puts your VAT and expenses at risk. A checklist and one cautionary story.

Shahlo is an accountant at a construction firm. One day the procurement department came back with a new supplier: rebar much cheaper than on the market, documents "all in order". Before signing the contract, Shahlo set aside an hour to check the company. That one hour later saved the firm from a big problem.

Why does a partner matter for tax?

The supplier gives you an invoice. On the basis of this document you credit VAT and deduct the expense from the tax base. If it later turns out that the supplier was not actually operating and the transaction existed only on paper, the tax authority may: - refuse to accept the VAT you credited - exclude the expense from the tax base - charge late payment interest (penya) on the underpaid tax

In other words, someone else's fault ends up coming out of your pocket.

What should be checked?

What is checkedWhy it matters
TIN and state registrationShows that the company really exists and is active
VAT payer status (if you intend to credit VAT)VAT on an invoice from a company that is not a VAT payer cannot be credited by you
Director and foundersIf one person heads dozens of companies, this is a warning sign
Actual address and warehouseYou need to know where the goods will be shipped from
Authority of the person signing the contractIf it is not the director, ask for a power of attorney
Documents confirming you actually received the goodsWaybill, acceptance certificate, warehouse receipt: proof that the transaction was real
Payment methodOnly through the bank, to the account number stated in the contract

What did Shahlo notice?

The company had been registered three months earlier, and the address given turned out to be an ordinary residential flat. The director also turned out to be the director of several other companies. Shahlo wrote an opinion against the contract, and the firm stayed with its familiar, reliable supplier.

Half a year later, a number of companies that had worked with that "cheap" firm began receiving questions from the tax authority.

What should be kept after the check?

  • The results of the check (with the date)
  • A copy of the partner's registration details
  • The contract, invoices and all documents confirming that the goods were received

This folder will be the strongest evidence in a tax audit that "we were careful".
