One ARG client wanted VAT advice and registration work to connect properly with future accounting. ARG explained how the technical VAT position affected returns, supporting records and the decisions that followed. The completed work left the client with a better organised file and a process that could be maintained beyond the initial task.
That practical connection matters whenever Bulgarian turnover, cross-border supplies or a change in activity may affect VAT status. The central question is not simply whether the business is profitable or small. It is whether the actual supplies, turnover timing and chosen scheme require registration, support a special regime or create deregistration risk.
ARG can help when you need to
Identify the person making each supply, its place of establishment, the customer’s status and the VAT place of supply. A foreign customer or foreign currency does not itself settle VAT treatment.
For a Bulgarian-established person, the 2026 domestic threshold is over €51,130 calendar-year turnover. Check Article 97a services and Article 99 EU acquisitions separately, even below that amount.
A domestic threshold application is due within seven days after exceedance; registration starts the next day. Foreign first supplies and reverse-charge services can require filing before tax becomes chargeable.
Prepare contracts, invoices, advances and the turnover calculation, plus authority to file. Plan invoicing, VAT registers, monthly returns and any VIES reporting from the effective date.
Bulgarian VAT registration can become compulsory before a business makes a profit or reaches its planned scale. For a taxable person established in Bulgaria, Article 96(1) of the Value Added Tax Act (ЗДДС) uses annual domestic turnover exceeding €51,130 from 1 January 2026. This is a calendar-year turnover test, not a profit test. The application is due within seven days after exceedance, and registration takes effect from the following day. A separate registration ground can apply even below the threshold. The NRA explains the current grounds and deadlines.
That is why this service starts with a registration review rather than with bookkeeping alone. A VAT decision changes invoicing, input tax recovery and the way the business presents itself to customers and suppliers. If you register too late, you risk noncompliance. If you register unnecessarily, you may create administrative burden and pricing issues that were not needed for the actual activity.
The domestic small-enterprise exemption has its own conditions. The business must be established in Bulgaria, remain at or below €51,130 domestic turnover in both the current and previous calendar years, and meet the requirements concerning ordinary registration and use of the EU small-enterprise scheme. Eligible domestic businesses do not need a separate application merely to use the domestic exemption. This does not erase obligations triggered by particular cross-border transactions. The NRA describes the domestic exemption separately from registration.
A “taxable person” is the person carrying on independent economic activity, not necessarily a limited company. A consultant working in their own name can therefore need a VAT review as much as a company selling goods. Employment itself is treated differently. Identify who supplies the goods or services under the contract before adding together sales or deciding whose VAT number belongs on the invoice.
A proper VAT review asks three things in order.
That review is commercially important because it tells you whether you can keep operating in the same way, whether invoices need to change, and whether the business should prepare for registration before the next supply. In a real advisory file, the decisive issue is often not the headline turnover alone, but how the supplies are characterised and where they are treated as taking place.
The place of supply is a legal rule identifying the country in which a transaction falls for VAT. It is not necessarily the customer’s postal address, the currency of payment or the location of a bank account. This is why foreign customers do not automatically make a sale exempt from Bulgarian VAT.
If you are planning market entry, a new contracting structure or a change in billing model, this is the point where VAT advice becomes part of wider establishment planning. A registration review is useful before the first invoices go out, because the VAT result can affect contract wording, pricing and downstream accounting.
The first step is to collect the facts that show where the business stands under the Bulgarian threshold test, then decide whether the small-enterprise route is genuinely available or whether mandatory registration is already in play.
For the 2026 domestic threshold, track qualifying turnover from the start of the calendar year and identify the actual day it exceeds €51,130. Article 168в defines the annual domestic turnover used by Article 96. A historical rolling twelve-month calculation and the former two-month acceleration rule do not describe this current test. Review the previous year as well where it affects eligibility for the small-enterprise exemption or deregistration. If correcting an older period, use the rules effective for that period rather than applying the 2026 test retrospectively. Current NRA registration guidance explains the calendar-year basis.
Reconcile the sales ledger to contracts, invoices, advance payments and the place-of-supply analysis. Include qualifying transactions in the domestic turnover calculation and document why any item is excluded. A transfer of a used business asset is not treated in the same way as an ordinary stock sale for this purpose. Certain financial, insurance and exempt property supplies can also matter, so excluding everything labelled “exempt” is not a reliable calculation method.
For example, a business with €50,000 of qualifying domestic turnover receives a further qualifying amount of €2,000 in the same calendar year. The threshold event is the date on which the statutory total exceeds €51,130; the business does not wait for its accountant to close the month. Check whether an advance payment contributes to that total and whether a credit note or cancelled contract actually changes the underlying taxable amount. Keep the calculation and supporting dates together.
The NRA’s approach means the legal question is not identical to gross revenue reporting. You have to decide which receipts count for VAT, when they count, and whether they belong in the Bulgarian turnover calculation at all. That is why customer type, supply location and existing VAT status are part of the factual file. A cross-border sale, a domestic taxable supply and a transaction outside the VAT base do not have the same effect.
For a business already operating in Bulgaria, the practical consequence is immediate. If the threshold has already been crossed, the filing deadline may already be running. That is the point at which a VAT registration review becomes a compliance control, not just a planning exercise. It also explains why a client should not wait for year-end accounts before asking the question.
A useful review separates the following elements.
Once those elements are clear, the business can see whether it has already crossed into mandatory registration or whether it remains below the threshold. That is the real value of the turnover exercise. It gives a defensible answer before the next invoicing or filing decision is made.
If the numbers are borderline, the safest next step is a documented turnover reconstruction rather than an assumption based on annual management accounts. That is the most reliable way to decide whether the registration clock has already started.
Purchasing a foreign advertising, software or consulting service can put Bulgarian VAT on the recipient through the reverse-charge mechanism. Article 97a therefore needs checking before the relevant advance or tax event. The same article can matter when a Bulgarian supplier provides qualifying business-to-business services taxable in another EU state, subject to the small-enterprise scheme exception. For goods acquired from another EU country, Article 99 has a separate €10,000 calendar-year acquisition threshold. These rules concern different transactions; neither should be replaced by a quick check of Bulgarian sales alone.

You need to choose the route that matches the actual supplies, not the route that sounds most convenient on paper. In Bulgarian VAT practice, that usually means deciding between ordinary domestic VAT registration under the Value Added Tax Act [ZDDS], participation in the EU small-enterprise regime, or a cross-border scheme such as OSS. The route matters because each one answers a different legal question. Ordinary registration asks whether the person is within the Bulgarian VAT system. The small-enterprise regime asks whether a person can remain outside ordinary domestic registration while still relying on a conditional EU framework. OSS answers a different problem, which is how to report certain cross-border B2C supplies without replacing the domestic registration analysis. The European Commission makes that separation clear on its One Stop Shop page, and the NRA says the special schemes are not a substitute for ordinary domestic VAT analysis.
Begin with where the supplier is established. A Bulgarian-established business uses the domestic rules described above. A business established in another EU state that validly uses the small-enterprise scheme in Bulgaria monitors both Bulgarian turnover and the €100,000 Union turnover ceiling. Another EU business outside that scheme may need registration before its first taxable Bulgarian supply, subject to the Union OSS and recipient-liable exceptions. A non-EU supplier has a corresponding first-supply analysis with the relevant Union or non-Union OSS exceptions. The NRA registration page sets out these separate routes under Article 96(1)–(4).
OSS is useful when the commercial model includes supplies that fall within the EU scheme framework, especially where the place of supply is in another Member State. But OSS does not eliminate the need to test whether Bulgarian domestic registration is already required. In other words, OSS can simplify reporting for particular cross-border sales, but it does not by itself answer whether the business is in or out of Bulgarian VAT registration. That is why ARG would not recommend treating OSS as a shortcut around the turnover review. The correct sequence is to identify the supply type, confirm the place of supply, and then decide whether the Bulgarian domestic rule or a special scheme governs that part of the business.
A practical example helps. If a company in Bulgaria sells mainly to Bulgarian customers, the domestic threshold analysis is central and OSS is usually not the starting point. If the same company also makes qualifying B2C cross-border sales into other EU Member States, OSS may be relevant for those supplies, but only after the domestic registration question is tested. A business with mixed supplies often needs both analyses at the same time.
The commercial reason for doing this carefully is simple. The wrong route can produce inconsistent invoicing, incorrect VAT treatment and avoidable reporting problems. The right route aligns the tax position with the actual sales model, which is especially important for businesses planning Bulgaria as a hub for regional trade.
For a Bulgarian-established person crossing the domestic threshold, submit the application within seven days after exceedance. Registration under Article 96(1) is effective from the following day, so the eventual receipt of the act must not become your assumed starting date. For foreign suppliers under Article 96(3) or (4), filing is generally required at least seven days before tax on the first relevant supply becomes chargeable. Under Article 97a, an advance can make tax chargeable before the final service is delivered. These differences make the signed contract and payment schedule as important as the sales total. Current filing rules should be applied to the actual registration ground.
The registration file is built around turnover evidence. The NRA’s registration materials point to the turnover calculation logic under Article 96 ZDDS, which means the application should be supported by the records that prove the taxable turnover figure and the date on which the threshold was reached. In practice, ARG would expect to assemble sales ledgers, invoices, contract and order dates, customer data and the place of supply analysis, because the legal test is not just a financial total. It is a VAT classification exercise. If the evidence does not show which supplies counted and when they counted, the authority can question the application or the timing.
The application should make it clear why registration is due and from which legal ground. That matters because the ground affects the effective date and the authority’s review. The NRA guidance also shows that the same turnover logic is used for both registration and deregistration work, so the file should be internally consistent. If the business has changed its model during the year, the application should explain that change rather than leaving the authority to infer it from raw figures.
For a client, the practical decision is whether to file immediately or first rebuild the turnover record. If the threshold has clearly been crossed, delay increases risk. If the position is borderline, the better step is to confirm the exact turnover date and then file on the correct basis. That is especially important for businesses that invoice across borders or have mixed supply chains, because the wrong filing basis can distort future VAT returns and downstream accounting.
The NRA’s current procedure provides a seven-day period to check the ordinary registration ground and issue a registration act or reasoned refusal. Article 96(3) and (4), Article 97a and Article 99 registrations have a three-day period. These administrative periods do not extend the applicant’s filing deadline. The application must identify its ground and the date it arose. Arrange a monitored correspondence email and confirm who has authority to file; an adviser’s access to bookkeeping software is not authority to represent the business before the NRA. The NRA explains its registration checks.
In practical terms, the work is finished only when the file can answer three questions clearly. Why registration is due. What evidence proves the turnover position. When the deadline started running. If those points are coherent, the filing is much less likely to create follow on issues in returns, invoicing or later audits.
Yes, a deregistration risk can arise if the activity changes, the person terminates, or the VAT position no longer fits the registered status. The NRA says deregistration can be mandatory in several cases, so it is not only a voluntary choice by the taxpayer. The practical consequence is significant. Once deregistered, the person may no longer charge VAT or deduct input tax unless the law specifically allows otherwise. That means a business that keeps invoicing as if nothing changed can create an immediate mismatch between its legal status and its accounts.
Falling sales do not automatically end registration. The applicable Article 108 ground depends on the original basis and on whether another mandatory ground remains. A voluntarily registered person generally cannot deregister by choice until twelve months have passed from the beginning of the calendar year following registration. A domestic business that exceeded the national threshold in the previous year cannot leave that ground before the current calendar year ends. Prepare current and previous calendar-year turnover statements rather than reusing an old rolling-turnover worksheet. The NRA sets out the current restrictions.
The key practical effect is on output VAT charging and input tax recovery. If the person is no longer registered, those rules generally stop. That affects pricing, contract performance and bookkeeping immediately. A business that expects to deregister should therefore check open invoices, ongoing supplies and any input tax claims before the status changes. Otherwise, it can end up with transactions recorded under the wrong VAT regime.
The NRA also states that some deregistration events require action within 7 or 14 days depending on the event. That means the deadline is event specific, not one universal period. From a client perspective, the useful next step is to identify the exact reason the risk has appeared, then check whether the event has already triggered a filing duty. If the business is restructuring, ceasing a line of activity or simply falling below the threshold, those facts should be documented before any invoice or return is prepared on the assumption that registration will continue.
Before deregistration, separate three questions: whether the legal ground permits it, which event determines the effective date, and what tax is due for the final period. Article 111 can treat retained assets on which input VAT was deducted as a taxable supply, subject to its exceptions. Reconcile inventory and fixed assets with the input tax actually claimed. A business that bought equipment shortly before stopping trade can face a material final liability even though it has no new customer sales.
For a business that wants to keep trading cleanly after a change, the real next consideration is whether to adjust invoicing and input tax treatment before the status shifts, not after the first incorrect return has been filed.
Agree who issues invoices, keeps purchase and sales registers, checks customer VAT numbers and submits returns. The ordinary VAT period is the calendar month; the return and registers are generally due by the fourteenth of the next month, including a return for a month without transactions. A VIES return is also needed where the relevant EU transactions occur. The NRA filing guidance distinguishes these obligations. Registration for a restricted ground such as Article 97a should not be treated as an automatic right to recover all purchase VAT. Review the registration basis and the use of each purchase before claiming input tax.
“Input tax credit” means a legally permitted deduction of VAT on purchases against output VAT; it is not a bank credit or a guaranteed refund of every supplier invoice. The business must satisfy the applicable deduction conditions, hold appropriate documents and use the purchase for qualifying activity. Private use, exempt supplies and statutory restrictions require separate treatment. These questions should be settled when the accounting workflow is arranged, so that registration produces correct invoices and returns from the effective date.
