CFC (КІК) reporting for Ukrainian IT owners: what to file and pay in 2026

If you are a Ukrainian tax resident and you own a foreign company, КІК forces two separate duties on you, and most owners conflate them. One is reporting: file an annual report on the company, with its financial statements, every year. The other is tax: pay Ukrainian tax on the company’s profit.

Filing and paying are different questions with different answers. For an active IT services or product company, the usual answer is that you owe no Ukrainian tax but you still must file. For a passive holding, IP, or royalty company, you file and you pay.

Sorting yourself into the right group is the first move. An operating company with real staff and service revenue files a report and, in most cases, attaches an exemption and pays nothing. A company built to hold money, IP, or shares at a low foreign tax rate files the same report and then pays 18% personal income tax plus a 5% military levy on profit you may never have taken out. For the first group, the largest exposure is a missed filing rather than a tax bill, and those penalties run high.

This guide is for that owner: a Ukrainian tax resident who already holds a foreign company (an Estonian OÜ, a US LLC, a UK Ltd, a Cyprus or Polish entity), or is about to open one. It assumes you have already weighed whether to incorporate abroad at all and what an Estonian OÜ really costs; here the subject is narrower and heavier: what КІК forces you to file and pay in Ukraine, current to 2026.

First question: are you even caught?

КІК applies only to a Ukrainian tax resident. If you have genuinely left and lost residency, you are outside the regime. But residency is sticky, and leaving during the war usually does not end it.

The test is a hierarchy, not a day count. You are a resident if you have a home in Ukraine; if you also have a home abroad, the tie breaks to where you have a permanent home; if you have one in both, it breaks to your centre of vital interests (family, main work, assets); only if that cannot be determined does the 183-day count decide. Ukrainian tax authorities treat the centre of vital interests as decisive even after a long absence. A Ukrainian appellate administrative court has confirmed that obtaining temporary protection abroad does not by itself make you a non-resident, so you still owe the КІК reports and notifications. “I live in Warsaw now” is not an exit if your family, company, and assets stayed in Kyiv.

A КІК is any foreign legal entity controlled by a Ukrainian resident. An Estonian OÜ, a US LLC, a UK Ltd, a Cyprus Ltd, and a Polish sp. z o.o. are all legal entities, so all are КІК candidates. A foreign sole proprietorship with no separate legal entity (the foreign analogue of a ФОП) is not a КІК.

The three control tests

You are a controlling person if any one of these holds:

Test	Threshold
Direct holding	More than 50% on your own
Joint holding	More than 10%, where Ukrainian residents together hold 50% or more
Actual control	Alone or with related Ukrainian residents, regardless of share

The joint-holding threshold was 25% for the 2022 and 2023 reporting years. It dropped to more than 10% from 2024. This is the co-founder trap. Four Ukrainian-resident founders each holding 25% of an Estonian OÜ are each controlling persons from 2024: each holds more than 10%, and together they hold 100%. None is “too small to report.” Where 25% or more is held jointly and nobody claims the full share, the law deems all of them controlling persons in equal shares.

Indirect ownership counts too. Shares held through other people or entities, and shares held by your related parties, are summed into your holding. One exception works in the owner’s favour: if you own the foreign company through a Ukrainian company that is itself the controlling person and bears the tax, you are not separately a controlling person.

Actual control is the trap

The control test that catches Ukrainian IT founders is the last one. Actual control is presumed on any one of: giving binding instructions to the company’s management; negotiating and agreeing the substantive terms of its deals that management then only rubber-stamps; holding a power of attorney for material transactions for more than a year; operating the company’s bank accounts or being able to block its payments; or being named as the founder or beneficiary when the company opens accounts.

A nominee Estonian or Cyprus director does not shield you if you, the Kyiv founder, run the company’s bank account and sign its contracts. That is actual control. The same facts feed a separate and harsher argument that the company is effectively managed from Ukraine, which can pull it into Ukrainian corporate tax outright.

КІК status is assessed as of 31 December of each year. Buy in and fully sell out before year-end and you may avoid controlling-person status for that year’s report, but the acquisition itself still triggered a notification.

What you file, and when in 2026

You carry two obligations, on different forms with different deadlines.

The first is the one-off notification (Повідомлення про КІК), filed within 60 calendar days of the triggering event: acquiring a share or starting actual control, selling or losing control, or founding or disposing of an interest in a structure without legal personality. The form is set by Ministry of Finance Order No. 512 and filed electronically through your Electronic Cabinet with a qualified electronic signature.

The second is the annual report (Звіт про КІК), on the form set by Ministry of Finance Order No. 254, filed together with your annual declaration. One report per КІК, with certified copies of that company’s financial statements attached.

Obligation	Form	Trigger	2026 deadline
Notification	Order No. 512	Acquiring or losing a share or control, within 60 days	60 days from the event
Annual report (legal entities)	Order No. 254	With the corporate income tax return	2 March 2026
Annual report (individuals)	Order No. 254	With the personal property and income declaration	1 May 2026
Full report after a short one	Order No. 254	When statements were not ready by the deadline	31 December 2026

These 2026 deadlines are for the 2025 reporting year. If the foreign financial statements cannot be ready in time, you file a short form with identification data only, then the full report by 31 December 2026. If the full report increases your taxable income and you file a clarifying declaration by year-end, no penalty or interest applies to that correction. For an individual, the personal income tax and military levy from the declaration are due by 1 August 2026.

Three things owners get wrong

The report is required even when nothing is owed. An exempt, dormant, or loss-making КІК is still reported, with zeros in the numeric fields. The CFC appendix to your declaration is mandatory, and you cannot file the report without the annual declaration even if you otherwise had nothing to declare. “No tax due” and “nothing to file” are different conclusions.

An audit is not mandatory. The financial statements are always attached, but an auditor’s opinion is required only if the tax authority doubts the statements and demands one, and not earlier than 15 months after the reporting period. Budget for keeping statements audit-ready, not for a yearly audit.

The third concerns older holdings, where owners assume a company bought years ago needs a catch-up notification. It does not: no notification is due for a share or control acquired before 31 December 2021. An owner who bought an OÜ in 2019 owes no notification for that original purchase. The annual report is still due from the 2022 reporting year onward, and any later sale, new acquisition, or change of control needs its own 60-day notification.

What you actually pay

The rate an owner pays depends on what they do with the profit. Three outcomes:

Scenario	PIT	Military levy	Total
Exemption applies	0%	0%	0% (report still filed)
Profit distributed to you before you file the report	9%	5%	14%
Profit retained in the company	18%	5%	23%

The 9% rate is the dividend rate for distributions from a non-resident, which a КІК is. The 5% dividend rate applies only to dividends from a Ukrainian company that pays corporate income tax, so it never reaches a foreign company’s profit. The planning point is plain: distributing the profit to yourself before you file is the cheaper way to get cash into a Ukrainian founder’s pocket. Retaining it costs 23% now, on money you never received, and only makes sense when the profit genuinely compounds inside the company. Retention is not a permanent 18%, though: distribute the profit within the second calendar year after the reporting year and the personal income tax recalculates down to the 9% dividend rate; distribute later and it does not. Profit already taxed at your level is not taxed again when it is later actually paid out.

The military levy matters for timing. It rose from 1.5% to 5% on individual income, effective 1 December 2024. The 2024 reporting year was still taxed at 1.5%, so the 2025 year, filed in 2026, is the first at 5%. Many vendor pages still print the owner rate as “19.5% (18% + 1.5%).” That is out of date. The current load on retained profit is 18% plus 5%.

The taxable base is the adjusted profit: the company’s pre-tax result from its unconsolidated financial statements, adjusted by a fixed list of differences, computed separately for each КІК, and converted to hryvnia at the National Bank’s weighted-average rate. A loss in one КІК does not offset profit in another. Because the conversion runs off the financial result, a cash balance sitting in euros or dollars can produce a hryvnia tax base even with nothing repatriated.

Foreign corporate tax the company actually paid reduces your Ukrainian personal income tax on the same profit, with documents, capped at the Ukrainian liability, with no refund of any excess. The credit covers the 18% (or 9%) personal income tax only. It does not touch the 5% military levy, which is always due in full. Even a company taxed heavily abroad leaves a residual 5% bill at the owner level.

One structural lever changes the rate. If a Ukrainian company owns the foreign entity and bears the tax, the charge is 18% corporate income tax at the company level, and you as an individual drop out of the personal 18% plus 5%. That is the mechanism behind holding a foreign company through a Ukrainian entity rather than personally.

Exemptions: who pays nothing, and still files

Three grounds remove the tax. None removes the report. An exemption frees you from calculating adjusted profit, but the report still carries the company’s identification and the exemption ground, with the tax lines left blank.

The classic exemption has two limbs, and you need a treaty plus one of them:

• A double-tax convention or tax-information-exchange agreement between Ukraine and the company’s jurisdiction, and
• Either the company pays profit tax at an effective rate of at least 13%, or its passive income is 50% or less of total income.

For an active IT business, the passive-income limb is the workhorse. Service and operating revenue is not passive; interest, royalties, dividends, and investment gains are. Keep passive income at or below half and an operating company qualifies. A company whose passive income exceeds half can still be treated as active, but only if it has real substance: it performs the functions, bears the risks, and has the staff and assets. A shell cannot claim it.

The effective-rate limb is where the popular structures fail. The 13% figure is five points below Ukraine’s 18% base corporate rate, and it is computed from the company’s own numbers rather than read off the foreign headline rate: profit-tax liabilities from the company’s tax reporting, divided by pre-tax profit from its financial statements, times 100.

An Estonian OÜ that retains profit pays 0% and fails it. A US LLC that pays no US corporate tax fails it. Cyprus, at a 12.5% headline, sits just below the line and does not clear it on the headline alone, though a company that genuinely pays 13% or more after the full computation can. A UK company is not exempt simply because its headline rate is 25%; the effective calculation has to clear 13% on the actual numbers.

The unconditional grounds need no treaty and no rate test. The main one for smaller companies: the aggregate income of all your КІК, from all sources, per the financial statements, does not exceed the equivalent of 2 million euros at the end of the reporting period. Three qualifiers decide it:

• it measures gross income, not profit;
• it aggregates across every КІК you control, not each company alone;
• it tests the position at the end of the reporting period.

A founder with three small foreign companies summing past 2 million euros loses it. The other unconditional grounds, a listed public company or a non-distributing charity, rarely fit this reader.

Which structure you hold, and how it fares

All five common structures are foreign legal entities, so all trigger КІК and an annual report for any Ukrainian-resident controlling person. The difference is whether tax is also due, and that turns on the exemption routes above.

Structure	Foreign profit tax	Against the 13% gate	Realistic exemption route
Estonia OÜ (retained profit)	0% on retained profit	Fails	Active income, or the 2 million euro floor
US LLC (single-member)	Usually 0% US federal	Fails	Active income, or the 2 million euro floor
UK Ltd	19% to 25%	Likely passes (treaty exists)	Effective-rate test
Cyprus Ltd	12.5% headline	Fails on the headline	Active income, or the 2 million euro floor
Poland sp. z o.o.	9% small / 19% standard	9% fails, 19% passes	Depends on the rate actually paid

Two structures carry a second system of obligations. A US LLC is a КІК for Ukraine even though the US treats a single-member LLC as a disregarded entity, which is exactly why it usually has no US corporate tax and fails the 13% test. On the US side it still files Form 5472 with a pro-forma 1120; US advisers HCVT and Loeb & Loeb note the penalty for not filing Form 5472 is 25,000 dollars per form. Two compliance systems, both live.

The compliant pattern is the same across all of them: file the notification and the annual report every year, exempt or not; engineer for the active-income exemption with real functions, staff, and contracts; and decide deliberately between retaining and distributing.

The outcome that is worse than CFC

A foreign company managed from Ukraine can be treated as having its place of effective management in Ukraine, which makes it a Ukrainian corporate-tax resident. The law is explicit: management decisions and current operations carried out mainly from Ukraine, or, as a tie-breaker, the company’s bank accounts, accounting, or staff managed from Ukraine, point to Ukraine. A company in that position is not treated as a КІК at all. It pays Ukrainian corporate tax directly, which is worse than the CFC charge, and the same bank-account-control facts that make you a controlling person feed this argument. Keeping the Ukrainian team on a Ukrainian entity that sells to the foreign company at arm’s length is what avoids it. The Estonia OÜ guide and the open-a-company-abroad guide cover this in depth.

Penalties, and the moratorium that is not an amnesty

The penalties are set as multiples of the subsistence minimum for an able-bodied person, fixed at 1 January of the reporting year being sanctioned. For the 2025 report, filed in 2026, that base is 3,028 hryvnia. For a 2026 event or reporting year, it is 3,328. Using the wrong year inflates every figure, which is why vendor “2026 penalty” pages disagree with each other.

Violation	Statute multiple	For the 2025 report (base 3,028)
Non-filing of the annual report	100 subsistence minimums, per КІК	302,800 UAH
Late filing of the report	1 per day, capped at 50	up to 151,400 UAH
Non-filing of the notification	300 subsistence minimums, per fact	908,400 UAH
Continued non-filing (30+ days after the penalty deadline)	5 per day, capped at 300	up to 908,400 UAH
Failure to reflect a КІК or its data	3% of the company’s income or 25% of adjusted profit, whichever is greater, capped at 1,000	up to 3,028,000 UAH

Paying a fine does not discharge the duty to file. A single ignored КІК can stack the report penalty, the continued-non-filing penalty, and a missed notification well past a million hryvnia before the failure-to-disclose tier is even reached. For a 2026 event the same multiples run off 3,328: the non-filing notification alone is 998,400.

The wartime moratorium is real but narrow. It waives the reporting penalties (the first through eighth paragraphs of the rule) for violations from 1 January 2022 through martial law, on one condition: that you cure every overdue obligation within six months after martial law ends. Administrative and criminal liability for breaches of the CFC rules is also suspended for that period. As of late June 2026, martial law remains in force.

What the moratorium does not cover matters more than what it does. It does not waive the CFC tax itself, the late-payment interest on it, the penalty for not producing transfer-pricing documentation, or the penalty for not producing primary documents on request. The tax was never suspended and is always due. The reporting penalty is suspended, conditionally and temporarily, and the КІК statute of limitations runs seven years, not the usual three.

Enforcement: the data is already in

Detection is no longer the open question. Ukraine joined automatic exchange under the Common Reporting Standard and made its first exchange in September 2024. The tax authority now receives, every year, data on foreign accounts held by its residents and by entities those residents control. CRS reaches fintech and payment institutions, not only banks, and the United States, outside CRS, is covered by FATCA. Domestic law adds a second channel: banks, payment providers, and e-money issuers that spot a resident’s stake in a foreign company must report it to the tax authority.

The reported numbers show how routine this audience already is. The tax authority states that 17,173 controllers filed 58,220 КІК reports for 2022 to 2024, 98% of them by individuals, with assessed liabilities of 4.9 billion hryvnia. The geography is exactly these structures: Poland 23%, Cyprus 10%, the United States 10%, the United Kingdom 10%, Estonia 9%. The authority has said the next step is analysing the reports and auditing controllers who did not file. The open question has shifted from whether they can see the company to when they assess it.

So the timing window is the whole game. A taxpayer who self-corrects an understatement is freed from penalties and interest until martial law ends, and the КІК moratorium waives the reporting penalties on the same condition. An owner who files and pays now, voluntarily, before that query lands, escapes both. Waiting gambles on the end date of a window that closes six months after the war does.

If you never filed: the catch-up sequence

For an owner who skipped 2022 to 2024, the rational move is to cure now, while the penalties are suspended, rather than wait for a query. The sequence:

1. Confirm your Ukrainian tax residency and whether you were a controlling person, for each company and each year from 2022.
2. File the report for each year, full, or short now with the full report by year-end, with the foreign financial statements. Statements in English need no translation; in any other language they need a notarised Ukrainian translation.
3. File any missing notification for an acquisition or control event after 31 December 2021. Pre-2022 acquisitions need none.
4. Determine the exemption for each company. Active companies are usually exempt and the report shows the ground, with no tax. Passive companies compute adjusted profit and the 18% plus 5%, or 9% plus 5% if you distribute before filing.
5. Where tax is due for a prior year, self-correct to avoid interest, and rely on the moratorium for the reporting penalties. Both are conditional on acting during martial law and the cure window.
6. Keep substance and source-of-funds evidence, and expect a query as CRS data lands. Answer it on time, with translated documents.

For the typical active IT company, this is paperwork with zero tax, done cheaply while penalties are paused. No official price exists for the compliance work itself. Ukrainian agency rate cards put report preparation in the low-to-mid five figures of hryvnia per company per year, more where adjusted profit has to be computed or several entities are involved, with notarised translation as a recurring line for non-English statements.

Liquidating the company ends the obligation going forward, but it is not a clean escape. The one-time tax-free liquidation relief closed at the end of 2021. For any company you hold today, liquidation proceeds flowing to you as a Ukrainian resident are taxable as foreign income, broadly at 18% plus 5%, or 9% if structured as a dividend before the deadline. You still owe the report for every year you controlled the company, plus a notification on liquidation. Walking away without liquidating is worse: the company keeps generating obligations, so closing it is a deliberate project with its own tax cost.

Strip the fear away and КІК reduces to one line: for an active IT company it is a report you cannot skip and a tax you usually do not owe, and the only costly mistake is silence.

And if the real goal is simply to get cash to a Ukrainian founder at a low rate, weigh a foreign КІК against Diia.City before assuming the foreign company wins.
