The check digit (DV) of a Colombian NIT is calculated by multiplying each digit of the NIT, from right to left, by the weights 3, 7, 13, 17, 19, 23, 29, 37, 41, 43, 47, 53, 59, 67, 71, adding up those results and dividing the sum by 11: if the remainder is greater than 1, the DV is 11 minus the remainder; if the remainder is 0 or 1, the DV is the remainder itself. Type your NIT without the DV to calculate it, or with a hyphen (900094071-0) to check whether the one you have is correct.
No hyphen to calculate the DV. With a hyphen (900094071-0) to validate it.
Each digit of the NIT, from right to left, is multiplied by a fixed table of weights (3, 7, 13, 17, 19, 23, 29, 37, 41, 43, 47, 53, 59, 67, 71), the results are added up and that sum is divided by 11. If the remainder is greater than 1, the DV is 11 minus the remainder; if the remainder is 0 or 1, the DV is the remainder itself. It is the same formula used by Colombia’s tax authority, the DIAN.
A wrong DV on your tax records can cause an electronic invoice to be rejected, or keep a third party from validating your company with the DIAN. It is worth fixing as soon as you catch it.
No. It applies to any NIT issued by the DIAN, whether for a company (legal entity) or an individual registered in the RUT.
No. The calculation runs entirely in your browser with JavaScript; the NIT you type never leaves your device or gets saved anywhere.
Informational tool; it does not replace accounting, tax or labor advice.
In Renaska Accounting, your company’s NIT is checked when you set up your tax details, and you get a warning if the check digit is wrong before it reaches your filings or your electronic invoices (via Alegra or Siigo).
