VAT payer registration remains valid until cancellation through exclusion from the VAT register. Cancellation can occur if a taxpayer’s taxable transactions fall below 1,000,000 UAH in the last year or upon their decision to cease operations with approved liquidation documents. Furthermore, registration is cancelled if a taxpayer switches to a single tax system not requiring VAT, fails to file VAT declarations for 12 months, or if their founding documents are invalidated by court. Finally, cancellation also happens in cases of court-ordered liquidation, exemption from VAT, the death or incapacitation of an individual taxpayer, or the termination of a joint activity agreement.
