VAT Filing in Montenegro: What Every Entrepreneur Must Know
Who must register for VAT
The registration threshold is €30,000 in taxable turnover over a rolling 12-month period. Cross that line, and VAT registration becomes mandatory. Stay below it, and you’re treated as a “small taxpayer” — outside the VAT system entirely.
What small-taxpayer status means (and the trap most people miss)
Being a small taxpayer isn’t just “you don’t charge VAT.” You must not charge or show VAT on invoices, you cannot deduct input VAT (it’s simply a cost you absorb), and you don’t maintain VAT books.
The trap: if you mistakenly show VAT on an invoice when you’re not a VAT taxpayer, the Tax Authority can force you to pay that VAT anyway — even if the error was unintentional.
Voluntary registration
If your turnover is below €30,000, you can choose to register by filing a written request — but voluntary registration commits you for a minimum of three years. This makes sense when you have significant input VAT to reclaim (equipment, fit-out, imports). It doesn’t make sense for B2C businesses without much input VAT, because adding 21% to your prices becomes a competitive problem.
Mandatory registration deadline
Once you cross €30,000, you must submit your registration application by the 20th of the month following the month you exceeded the threshold. Missing this is a punishable offence. The Tax Authority must issue a registration decision within 7 days. Your VAT status begins on the date in that decision, not the date you applied.
Registration uses Form PR PDV-1, submitted electronically via the IRMS portal (requires a qualified electronic signature certificate). Your VAT number is your PIB with the prefix “ME”.
VAT rates in 2026
Montenegro operates four tiers. Getting the rate wrong is one of the most common and expensive mistakes.
Standard rate: 21%
The default for any supply that doesn’t qualify for a reduced or zero rate.
Reduced rate: 7%
Covers specific essentials: basic foodstuffs (bread, flour, milk, meat, eggs, sugar), medicines, certain medical devices, textbooks, drinking water (not bottled — this distinction regularly causes errors), public passenger transport, agricultural inputs, menstrual products, and baby diapers.
These categories are defined narrowly. If your product sits on a boundary, check implementing guidance before you scale.
Reduced rate: 15%
Covers tourism and selected services: accommodation, food and drink service in hospitality (excluding alcoholic beverages, sugary soft drinks, and coffee), books, event tickets, marina services, solar panels, and hairdressing.
The hospitality exclusions catch businesses constantly. Charging 15% on alcohol, soft drinks, or coffee is wrong under the Law and shows up as “incorrect VAT calculation” in audits.
Zero rate: 0%
Primarily exports. You must still invoice correctly and maintain evidence supporting 0% treatment — a weak audit file turns 0% into 21% fast.
Recent change: Amendments from February 2026 extend VAT to construction land, effective 1 April 2026.
Monthly filing and payment
Once VAT-registered, the rule is simple: file and pay every month, whether or not you had activity.
Tax period: One calendar month. No quarterly option.
Deadline: Both the return and payment are due by the 15th of the following month. Even if you owe nothing, you must file a nil return. If the 15th falls on a weekend or holiday, the deadline extends to the next working day.
The return is prescribed by the Tax Authority and filed electronically. An amended form has been in use since the January 2025 tax period.
Important: When filing deadlines are extended (as happened during the IRMS portal rollout), payment deadlines often don’t move. Plan your VAT cash flow accordingly.
Invoices and records
VAT compliance is invoice-driven. Wrong invoices mean wrong returns.
Invoice requirements
VAT taxpayers must issue an invoice for every supply, including advance payments. For B2B supplies, a compliant invoice must contain: issue date and sequential number, seller’s name/address/VAT number, buyer’s name/address, date of supply, description and quantity, net amount, VAT rate, VAT amount, and gross amount.
For exempt or 0% supplies, state that VAT was not charged and reference the legal basis.
Electronic fiscalization
Montenegro requires real-time reporting of invoices to the Tax Authority. Fiscal invoices carry additional mandatory data: operator code, taxpayer identification code, unique invoice ID, and payment method. The Tax Authority cross-references fiscalized data against VAT returns — mismatches trigger scrutiny.
Records and retention
Maintain a sales invoice book, purchase invoice book, and (for importers) a record of import VAT paid. Retain all invoices, returns, and supporting documents for at least 5 years (20 years for real estate documentation).
Common mistakes that lead to penalties
Most VAT penalties aren’t about fraud — they’re about sloppy process.
- Late registration after crossing €30,000 — the 20th-of-next-month deadline is a punishable offence itself
- Late filing or not filing the monthly return
- Late payment even if you filed on time — treated as a more serious offence
- Wrong rate application — charging 7% on bottled water, 15% on alcohol/coffee in hospitality, or treating prepared food as “basic foodstuff”
- Claiming input VAT without proper documentation — a missing invoice means you lose the deduction
- Non-compliant invoices — missing VAT number, rate, or fiscal data
- Recordkeeping failures — not maintaining VAT books or not retaining documents for the required period
Penalties and interest
Fine ranges
| Offence type | Legal entity | Responsible person | Entrepreneur |
|---|---|---|---|
| Procedural (late filing, late registration, invoice issues) | €3,000–€10,000 | €800–€2,000 | €1,000–€4,000 |
| Substantive (incorrect calculation, late payment, wrong deductions, missing records) | €6,000–€20,000 | €1,500–€2,000 | €2,000–€6,000 |
Fiscalization fines are separate and steeper: €8,000–€40,000 for a legal entity that fails to issue fiscal invoices, €4,000–€20,000 for invoices missing fiscal data.
Late-payment interest
Beyond fines, late VAT payment accrues statutory default interest. For January–June 2026, the rate is 10.15% per year. Interest runs while disputes play out.
VAT refunds
If your deductible input VAT exceeds output VAT, the difference becomes a credit carried forward or a refund on request.
Processing deadlines: 60 days from filing (standard), or 30 days if you’re a predominant exporter or show excess input VAT in more than three consecutive periods. Outstanding tax debts are automatically offset against refunds.
Requesting a refund invites a risk review. The better your invoice file and reconciliation documentation, the less painful the process.
