This content applies specifically to South Korea.

If you have a VAT interim payment notice for the second taxable period of 2026, the standard payment deadline is November 2, 2026. Corporations required to file an interim return must file and pay by October 26, 2026, unless a payment extension applies.

Separate the payment from the return

Individual general VAT taxpayers and small corporations generally pay the notice amount without filing a separate interim return. The notice bills 50% of the tax paid for the preceding taxable period, here the first half of 2026. You can check the amount through Hometax, the National Tax Service's online tax portal, to plan for the payment.

VAT interim notice checks in one place

The original article on OnBinder helps you distinguish payment obligations from filing obligations, with business categories and deadlines shown together. Its Hometax steps explain where to check the notice, pay and confirm processing, while separate guidance covers switching to a return and checking extensions.

A check when sales have fallen

If you have lower sales but unchanged tax due, the sales test can still be relevant. Compare sales from July 1 to September 30, 2026 with sales from January 1 to June 30, 2026: the current amount must be less than one-third of the earlier amount. Equality does not qualify. A qualifying switch to an interim return requires filing by October 26, 2026; cash shortage alone is insufficient.

Check the business category first

For a corporation, check whether total supply value from January 1 to June 30, 2026 is less than 150 million won. Supply value means transaction amounts excluding VAT. Exactly 150 million won falls outside this small-corporation definition.

If you are covered by an automatic extension, payment is due December 28, 2026; the filing deadline remains unchanged. Confirm eligibility in Hometax rather than assuming the extension applies.

Other payment questions

Is a notice for exactly 500,000 won excluded?

No. The amount-based exclusion applies only when the amount billed this time is less than 500,000 won.

Does a missing paper notice mean no payment is due?

No. Check the notice amount on Hometax, and contact the local tax office if checking it proves difficult.

Is the notice amount charged again at the final return?

The notice amount is deducted as tax already paid in the next final return. The final liability reflects actual transactions during the taxable period.

As a next step, you can log in to Hometax and check the amount and deadline under View Interim Notice Amount. (verified value November 2, 2026 standard payment deadline for 2026 second-period interim notices; December 28, 2026 for eligible automa · source hometax.go.kr · checked 2026-10-05)
