Ukraine Electronic Invoicing & Digital Tax Reporting — Self-Employed Skill v1.0

This skill explains how a Ukrainian self-employed person interacts with the State Tax Service's digital machinery: issuing and registering the VAT tax invoice (податкова накладна) in the Unified Register (ЄРПН), the risk engine that can freeze that registration (СМКОР), the electronic VAT administration system (СЕА ПДВ) and its VAT account, software fiscal receipts (ПРРО) for anyone taking money at retail, qualified electronic signatures (КЕП), the taxpayer portal (Електронний кабінет), and where SAF-T UA stands in 2026.

The single most important split: a non-VAT ФОП has light duties (keep primary documents, run a ПРРО if they take cash/card retail payments) and never touches ЄРПН. A VAT-registered taxpayer carries the full electronic burden — tax invoices, ЄРПН registration deadlines, the СЕА ПДВ VAT account, and exposure to СМКОР blocking.

Wartime note. Martial law has been in force since 24 Feb 2022 and remains in force in 2026. Several deadlines below run on the special martial-law schedule, which differs from the peacetime Tax Code baseline. When martial law ends the peacetime ЄРПН deadlines resume. Always confirm the current regime before quoting a date.

Conservative defaults

When facts are missing, assume the position that minimises filing risk and penalty exposure:

1. If unsure whether the client is VAT-registered → treat them as a non-VAT ФОП for invoicing (no ЄРПН, no tax invoice) but flag that VAT status must be confirmed, because if they are VAT-registered, missing ЄРПН registration is the costlier error.
2. Register the tax invoice as early as possible — never wait for the deadline; the ЄРПН penalty clock and the СМКОР blocking risk both grow with delay.
3. Assume a ПРРО is required for any cash or card retail settlement unless the client is clearly in an exempt category (e.g. Group 1 ФОП within its narrow exemption). Default to issuing a fiscal receipt.
4. Assume the supplier registers the tax invoice, not the buyer — only the seller can register a податкова накладна in ЄРПН.
5. Treat any "blocked invoice" as urgent — unblocking has its own deadlines; do not let it sit.
6. Pin amounts and thresholds to 1 January 2026 values and verify against tax.gov.ua before relying on a figure for a filing.

Section 2 — Who must do what

A. Non-VAT ФОП (single tax Group 1/2/3 non-VAT, or general-system non-VAT)

• Non-VAT ФОП obligations — A sole proprietor not registered for VAT has no податкова накладна and no ЄРПН obligations whatsoever. Their electronic duties are limited to: - Primary documents (первинні документи). Issue and keep invoices/acts (рахунок, акт виконаних робіт), contracts, and bank records to substantiate income. A non-VAT ФОП's "invoice" is a commercial document (рахунок-фактура / invoice), not a VAT податкова накладна — these are different things and must not be confused. - ПРРО fiscal receipts — required when the ФОП accepts cash or card payments at retail (see Section 4). Group 1 ФОП are largely exempt; Groups 2–3 generally must use a ПРРО. - Електронний кабінет for filing the single-tax declaration and viewing obligations, accessed with a КЕП. A non-VAT ФОП never registers anything in ЄРПН and is never blocked by СМКОР.

B. VAT-registered taxpayer (ФОП or company)

• VAT-registered taxpayer obligations — A taxpayer registered for VAT (mandatory once taxable supplies exceed ₴1,000,000 over 12 months, or voluntary before that) carries the full electronic load: - Issue a податкова накладна for each taxable supply (and розрахунок коригування / adjustment calculation for changes). - Register every податкова накладна in ЄРПН within the statutory deadline (Section 3). - Operate within СЕА ПДВ — the registration limit (∑Накл formula) and the VAT account (Section 3). - Survive СМКОР — risk monitoring may suspend (block) registration of an invoice. - Run a ПРРО if also doing retail settlements. - Authenticate everything with a КЕП. > A Group 3 ФОП may elect the 3% single-tax + VAT path (vs the 5% non-VAT path). Electing VAT pulls the ФОП fully into ЄРПН / СЕА ПДВ / СМКОР. Defer the rate-vs-VAT decision to ua-single-tax; this skill handles the mechanics once VAT-registered.

Section 3 — Tax invoice (податкова накладна) & ЄРПН registration

What it is

• Податкова накладна (ПН) and ЄРПН — The податкова накладна (ПН) is the VAT document a registered supplier issues for each taxable supply. It is the buyer's basis for an input-VAT credit (податковий кредит) — but only once it is registered in ЄРПН. An unregistered ПН gives the buyer no credit, so timely registration is a commercial obligation as much as a tax one. The Єдиний реєстр податкових накладних (ЄРПН) is the single State-Tax-Service register through which all ПН and розрахунки коригування (РК / adjustment calculations) pass. Only the supplier registers a ПН; the buyer cannot.

When the ПН arises

• First event rule — By default a ПН is dated to the first event — the earlier of (a) payment received or (b) goods/services supplied (Tax Code Art. 187). The registration deadline runs from that ПН date. (Tax Code Art. 187)

Registration deadlines

ЄРПН registration deadlines — martial law

ПН/РК dated	Register in ЄРПН by
1st – 15th of the month	5th calendar day of the following month
16th – last day of month	18th calendar day of the following month

Registration is temporarily permitted on weekends during martial law (so a deadline falling on a weekend is not pushed forward, and you can register on the day). Verify the current working/weekend rule before relying on a weekend submission.

ЄРПН registration deadlines — peacetime baseline

ПН/РК dated	Register in ЄРПН by
1st – 15th of the month	last day of the same month
16th – last day of month	15th of the following month

• Outer backstop for registration — Outer backstop in either regime: ПН/РК cannot be registered later than the relevant maximum window the Tax Code allows (commonly cited as up to ~365 days for late registration before the right to register lapses) — verify the exact outer limit for the period in question.

Late-registration penalties

• Late registration penalty scaling — Penalties scale with the length of the delay, broadly 2% up to 25% of the VAT amount in the invoice (graduated by days late), with separate (heavier) rules for invoices that are never registered. Confirm the current banded percentages on tax.gov.ua before quoting them to a client.

СЕА ПДВ (electronic VAT administration) and the VAT account

• СЕА ПДВ, VAT account, registration limit — Registration of a ПН in ЄРПН is gated by the СЕА ПДВ (Система електронного адміністрування ПДВ). Each VAT payer has: - A dedicated electronic VAT account (електронний ПДВ-рахунок) opened automatically in the Treasury. The payer tops it up; funds there are used to pay VAT liabilities. - A registration limit (∑Накл / реєстраційна сума) — the maximum VAT amount of invoices the payer can register at any moment. Simplified, it is built up from the VAT on received registered invoices plus customs VAT paid plus money lodged on the VAT account, minus the VAT on issued registered invoices and VAT declared. If the registration limit is insufficient, the system will not let the supplier register the ПН until they top up the VAT account (or until incoming registered invoices raise the limit). This is a cash-flow trap that catches growing businesses — flag it whenever a client reports "the system won't register my invoice and it isn't blocked."

СМКОР — blocking (зупинення реєстрації) of tax invoices

• СМКОР definition and layers — СМКОР (Система моніторингу відповідності ПН/РК критеріям оцінки ступеня ризиків; risk-criteria monitoring system, under CMU Resolution No. 1165) automatically screens each ПН/РК on submission. If it trips a risk criterion, registration is suspended (заблокована / зупинена) — the invoice is neither registered nor rejected; it is frozen pending documentary justification. Three layers the system checks: 1. Unconditional-registration criteria — small/low-risk invoices pass automatically. 2. Risky-taxpayer status (ризиковий платник) — if the payer is flagged as risky, its invoices block by default. Risk can be inherited (e.g. a new entity with the same director/founder/accountant as a flagged one is cross-matched and tagged) and must be actively contested. 3. Risk criteria for the operation — e.g. mismatch of input vs output product/service codes (УКТ ЗЕД / ДКПП): "bought bricks, sold construction services" looks anomalous and blocks. (CMU Resolution No. 1165)
• Data Table (Таблиця даних платника) pre-emption — Pre-empting blocks — the Data Table (Таблиця даних платника). A payer can file a Таблиця даних declaring its normal input and output codes. Once the tax commission accepts it, future invoices with those codes are not suspended for that reason — the single most effective protection against repeat blocking.
• Blocked invoice process — When an invoice is blocked: the payer files documentary explanations and supporting documents through the Електронний кабінет; the regional commission decides to register or refuse within the statutory window. A refusal can be appealed administratively to ДПС and then in court. Treat every block as time-sensitive — there are deadlines to submit documents and to appeal.

Section 4 — ПРРО fiscal receipts (software RRO)

• ПРРО definition — A ПРРО (програмний реєстратор розрахункових операцій) is the software fiscal cash register — a free State-provided app (and third-party equivalents) that issues fiscal receipts and reports settlements to ДПС in real time. It replaced/supplemented the old hardware РРО.

Who must use a ПРРО (or РРО)

ПРРО/РРО requirement by taxpayer type

Taxpayer	ПРРО / РРО required?
Group 1 ФОП	No — broad exemption, except sales of technically complex goods under warranty, medicines/medical devices, jewellery & precious-metal goods
Group 2 ФОП	Yes for cash/card settlement transactions (obligation does not depend on turnover or activity in 2026 — verify wording for the client's exact activity)
Group 3 ФОП	Yes for cash/card settlements; also triggered once income passes the РРО threshold
General-system FOP / companies	Yes for cash/card settlements

• Turnover trigger for ПРРО/РРО — ~220 minimum wages as of 1 January (≈ ₴1.9 m for 2026 — verify the exact minimum wage and resulting figure) UAH (verify exact figure)
• High-risk goods override — Certain high-risk goods (jewellery, medicines, technically complex goods, excisable goods) require a ПРРО regardless of turnover or group.

Fiscal receipt mechanics

• Fiscal receipt issuance and timing — - Issue a fiscal receipt (фіскальний чек) in paper or electronic form for every settlement. A non-fiscal "sales receipt" does not satisfy the obligation. - Card payments: the fiscal receipt must follow the bank transaction promptly (commonly cited as within ~5–10 minutes). A large gap between the bank transaction and the ПРРО receipt is itself a flagged violation. - Authenticate the ПРРО with a КЕП; receipts and the daily Z-report flow to ДПС.

Penalties

• ПРРО fiscal violation penalty — 100% of the value of goods/services sold with a fiscal violation for a first offence; 150% for each subsequent one % (Full (post-moratorium) fines in 2026 — verify current banding before quoting)

Important distinction. The фіскальний чек (ПРРО receipt, retail settlement evidence) and the податкова накладна (VAT document for ЄРПН) are entirely different documents serving different systems. A non-VAT ФОП issues fiscal receipts but never a ПН.

Section 5 — КЕП & Електронний кабінет

• Section intro —

Qualified electronic signature (КЕП)

• КЕП definition and options — A кваліфікований електронний підпис (КЕП) is the legally binding e-signature used to sign and submit everything electronic to the State — ПН, declarations, ПРРО receipts, appeals. Options: - File-based КЕП from an accredited provider (наприклад ПриватБанк, Дія, Вчасно, etc.). - Дія.Підпис (Diia mobile signature) — issued free to individuals/ФОП. - Cloud КЕП — stored with a provider, used without a hardware token. - BankID / MobileID for identification (read-level access to some services). КЕП for individuals/ФОП is commonly obtained free via Дія or bank apps (e.g. Privat24).

Електронний кабінет

• Електронний кабінет portal structure — The Електронний кабінет платника (cabinet.tax.gov.ua) is the ДПС taxpayer portal. It has: - A public part (no login) — registers, forms, calendars, validity checks. - A private part — accessed with a КЕП (or Дія.Підпис / cloud КЕП / id.gov.ua), where the taxpayer files declarations, registers ПН/ЄРПН, monitors the СЕА ПДВ VAT account and registration limit, manages ПРРО, responds to СМКОР blocks, and views liabilities. Most self-employed e-filing in this skill happens through the Електронний кабінет, signed with a КЕП.

Section 6 — SAF-T UA status

• SAF-T UA definition — SAF-T UA (Standard Audit File for Tax — Ukrainian standardised XML accounting file) is Ukraine's standardised audit-data format, built for the tax authority's e-audit (електронний аудит) programme.
• SAF-T UA status as of May 2026 — Status as of May 2026 — verify before relying: - The general mandatory periodic SAF-T filing rollout was formally withdrawn (Ministry of Finance, mid-2025). The earlier phased plan (large taxpayers from 2025, all VAT payers by Jan 2027) is no longer the active mandate. - SAF-T UA persists as an on-demand obligation: large taxpayers must produce the SAF-T UA XML file on request during a tax audit, not as routine periodic reporting. - The e-audit system launched 1 January 2026 uses the SAF-T UA format as its data backbone; the current schema is SAF-T UA 2.0 (simplified structure published late 2024). - For a typical self-employed ФОП / small taxpayer, there is no routine SAF-T UA filing obligation in 2026. Small/medium taxpayers were never the immediate target, and the blanket "all VAT payers by 2027" requirement has been withdrawn.

Flag for the reviewer. The SAF-T timeline has changed repeatedly. Treat "small taxpayers have no SAF-T duty in 2026" as the working position but confirm against tax.gov.ua / a Ukrainian accountant for any client near the large-taxpayer threshold (₴500 m revenue over four quarters) or before advising on 2027.

Section 7 — Worked examples

Example 1 — Non-VAT Group 3 freelancer (no ЄРПН at all)

Olena is a Group 3 ФОП on the 5% (non-VAT) path, an IT consultant invoicing a foreign client.

• VAT-registered? No. → No податкова накладна, no ЄРПН, no СЕА ПДВ, no СМКОР.
• She issues a commercial invoice (рахунок-фактура) and signs an акт with the client; she keeps these as primary documents.
• No retail cash/card settlement → arguably no ПРРО for this work (bank-to-bank receipts for services to a business client). If she ever takes cash from individuals, the ПРРО question reopens.
• Files her single-tax declaration through the Електронний кабінет, signed with her КЕП (free via Дія).

Outcome: lightest digital footprint — primary documents + e-cabinet + КЕП only.

Example 2 — VAT-registered Group 3 ФОП issuing and registering a ПН

Petro is a Group 3 ФОП on the 3% + VAT path. He supplies services on 8 May 2026 for ₴120,000 incl. 20% VAT (₴20,000 VAT).

• First event = supply on 8 May → ПН dated 8 May.
• 8 May falls in the 1st–15th band → register in ЄРПН by 5 June 2026 (martial-law rule).
• Before registering, the system checks his registration limit (∑Накл) in СЕА ПДВ. If it is below ₴20,000, he must top up his VAT account to register.
• He registers via the Електронний кабінет, signed with his КЕП. Best practice: register the same week, not at the 5 June deadline.

Outcome: ПН registered on time; buyer gets input credit; no penalty.

Example 3 — A blocked invoice (СМКОР)

Same Petro registers a ПН where the output service code does not match his historical input codes. СМКОР suspends registration (зупинення реєстрації).

• The ПН is frozen, not rejected. The buyer cannot claim credit yet.
• Petro submits explanations + supporting documents through the Електронний кабінет within the statutory window; the regional commission decides.
• To prevent recurrence he files a Таблиця даних платника listing his normal input/output codes; once accepted, future invoices with those codes won't block for that reason.
• If refused, he appeals to ДПС and, if needed, to court.

Outcome: registration restored after documentary justification; Data Table filed to stop repeat blocks.

Example 4 — Group 2 ФОП taking card payments at retail (ПРРО)

Mariya is a Group 2 ФОП running a small café, non-VAT.

• Non-VAT → no ЄРПН/ПН.
• Cash/card retail settlements → she must run a ПРРО and issue a фіскальний чек for every sale; card receipts must follow the bank transaction promptly.
• ПРРО is signed/operated with her КЕП; daily Z-reports flow to ДПС.
• Failure to issue fiscal receipts → 100% / 150% penalties.

Outcome: no VAT machinery, but full ПРРО/fiscal-receipt discipline.

Section 8 — Tier 2 + Reference + Checklist

Tier 2 ambiguities (escalate to a credentialed Ukrainian accountant)

• Whether a specific activity/group combination triggers ПРРО (the exemptions and thresholds have edge cases — high-risk goods override the group exemption).
• The exact current ЄРПН outer registration window and the banded late-registration penalty percentages for the period in question.
• СМКОР unblocking strategy, Data Table drafting, and removal from ризиковий платник status — these are advisory/contentious and often litigated.
• SAF-T UA applicability for any client near the large-taxpayer threshold or planning past 2026.
• The VAT-vs-non-VAT election for a Group 3 ФОП (3% vs 5%) — defer to ua-single-tax.
• Anything during a martial-law deadline change — confirm the live regime.

Reference

• Tax Code of Ukraine (Податковий кодекс) — Art. 187 (date of liability), Art. 201 (tax invoices & ЄРПН).
• CMU Resolution No. 1165 — СМКОР risk criteria, blocking and Data Table procedure.
• Law No. 265/95-ВР on RRO/ПРРО and fiscal receipts.
• State Tax Service — tax.gov.ua / dps.gov.ua; portal cabinet.tax.gov.ua.
• PwC Worldwide Tax Summaries — Ukraine (VAT threshold ₴1 m, rate 20%, ЄРПН/СЕА overview).

Self-employed e-invoicing checklist

• Confirm VAT status — VAT-registered or not? (Determines whether ЄРПН applies at all.)
• Obtain/renew a КЕП (free via Дія / bank) and access the Електронний кабінет.
• Non-VAT: issue/keep primary documents (рахунок, акт); confirm whether a ПРРО is required and issue fiscal receipts for retail settlements.
• VAT-registered: for each supply, date the ПН to the first event and register in ЄРПН by the deadline (martial-law: 5th / 18th).
• Monitor the СЕА ПДВ registration limit (∑Накл) and top up the VAT account before registering when needed.
• File a Таблиця даних to pre-empt СМКОР blocking; treat any blocked invoice as urgent.
• Register invoices early, never at the deadline.
• Confirm there is no routine SAF-T UA filing duty for the client (small taxpayer) — flag if near the large-taxpayer threshold.

PROHIBITIONS

• Prohibitions list — - Do NOT issue or "register" a податкова накладна for a non-VAT ФОП — they have no ПН and no ЄРПН access. Confusing a commercial рахунок-фактура with a VAT податкова накладна is a category error. - Do NOT tell a buyer they can register a supplier's tax invoice — only the supplier registers in ЄРПН. - Do NOT quote ЄРПН registration deadlines without stating which regime (martial-law vs peacetime baseline) applies — they differ and the wrong one causes penalties. - Do NOT state exact late-registration or ПРРО penalty percentages, the ₴ ПРРО turnover trigger, or the SAF-T threshold as settled fact without verifying current figures on tax.gov.ua — they are pinned to the minimum wage and to changing law. - Do NOT assert that SAF-T UA is mandatory periodic reporting for small taxpayers — as of May 2026 it is on-demand for large taxpayers; verify before advising past 2026. - Do NOT advise on СМКОР unblocking, Data Tables, or risky-status removal as if routine — these are advisory/contentious matters for a credentialed practitioner. - Do NOT finalise any filing without КЕП-signed submission through the official Електронний кабінет. - Do NOT treat this skill as a substitute for credentialed review.
