Is it worth registering for VAT voluntarily?

Yes, registering for VAT voluntarily can pay off even before you hit the mandatory EUR 45,000 threshold — but only when your clients are themselves VAT payers (B2B) and you incur a lot of input VAT. If you sell mainly to end consumers (B2C), voluntary registration usually either raises your price by 21% or eats into your margin, so there is no rush. In short, the decision comes down to two things: who your clients are, and how much VAT you pay on your own purchases.

In this article we explain when voluntary VAT (value added tax) registration actually helps and when it hurts: how input VAT recovery works, why your VAT-payer status matters to B2B partners, and how 21% VAT changes a B2C price. All figures here are indicative (2026) — always verify current rates and thresholds on the State Tax Inspectorate (VMI) website.

Voluntary VAT registration is not a tax break but a tool: in B2B it unlocks input VAT recovery, while in B2C it adds a 21% markup that someone still has to absorb.

What voluntary VAT registration is and how it differs from mandatory

For a Lithuanian business, the obligation to register as a VAT payer kicks in once turnover exceeds the EUR 45,000 threshold over the last 12 months (unchanged in 2026). We describe exactly when that duty triggers and how the period is counted in our article on the mandatory EUR 45,000 VAT threshold.

But the law also lets you register voluntarily — well before that threshold, even with very low turnover. This is often weighed by founders who have just started a business in Lithuania and immediately work with larger partners. Note that for a foreign (non-established) business there is no threshold at all — the obligation arises from the very first taxable transaction.

Advantage: input VAT recovery

The biggest plus of voluntary registration is the right to deduct input VAT. Once you are a VAT payer, you add output VAT to your sales but subtract all the VAT you paid when buying goods, services, equipment or materials. We explain exactly how this offset works, step by step, in our article on what VAT is and how it works.

For a non-VAT payer, input VAT is simply a cost — it is baked into the price and never comes back. For a VAT payer, that same VAT is recoverable. So if your activity involves a lot of taxable purchases (subcontracting, equipment, stock), voluntary registration can genuinely lower your costs.

Advantage: credibility with B2B partners

The second argument is status and credibility. When your clients are VAT payers themselves, the VAT you charge is no burden to them: they simply deduct that input VAT. Meanwhile, VAT-payer status signals that you operate seriously and can issue a proper VAT invoice.

Some larger buyers even avoid non-VAT payers, because purchases from them carry no deductible VAT. This matters especially if you operate through a UAB and want to look like an equal partner — and we cover what taxes a UAB pays separately.

Drawback: B2C prices jump by 21%

The biggest downside appears when working with end consumers (B2C). A private individual cannot deduct VAT, so the 21% VAT you charge is a pure price increase for them. You have two options, and both are painful:

• Raise the price by 21% — then you become more expensive than non-VAT competitors.
• Keep the same price — then you cover the VAT out of your margin, and your net earnings fall.

That is why in a purely B2C business (a hair salon, small retail to consumers, services to individuals) voluntary registration usually is not worth it until it becomes mandatory.

Which rate will you add: 21%, 12% or 5%?

Before calculating the price impact, check which rate applies to your product or service. The standard rate is 21%, but from 2026 reduced rates also apply: 12% (accommodation, passenger transport, catering, culture) and 5% (books, medicines). These and other changes are reviewed in our article on what changes for business from the 2026 reform.

If you sell reduced-rate goods, the price "jump" for a B2C client will be smaller than 21%, so the harm from voluntary registration is milder too. Always verify the exact rate for your activity with VMI.

When voluntary registration is genuinely worth it

To sum up, voluntary VAT registration usually pays off when:

• Most of your clients are VAT payers (B2B), so the VAT you charge is neutral to them.
• You have a lot of taxable purchase costs (subcontracting, equipment, goods) whose VAT you want to recover.
• You are investing in a launch — buying a lot of equipment or stock before you start earning, so recoverable input VAT accumulates immediately.
• You work with foreign or EU partners for whom your VAT-payer code is essential to the deal.

When it is better to wait until the EUR 45,000 threshold

It is better not to register voluntarily when:

• You sell mainly to individuals (B2C) and compete on price.
• You have little input VAT (e.g. you sell your time or expertise, not goods).
• You do not want the extra admin burden — VAT returns, bookkeeping and deadlines.

In these cases it is often smarter to stay a non-VAT payer until turnover naturally approaches the EUR 45,000 threshold.

EU distance selling: the EUR 10,000 threshold

If you sell goods or certain services to individuals in other EU countries (e.g. you run an online shop), track the EUR 10,000 EU distance-selling threshold separately. Once you exceed this combined annual threshold, sales to EU consumers generally must carry the destination country's VAT rate (often via the OSS system). Sometimes this in turn pushes you to register for VAT earlier — check the exact procedure with VMI.

Example: a B2B versus B2C calculation

Let us compare the same business in two scenarios (all figures indicative, rate 21%).

B2B scenario. Over a year you buy services and equipment for EUR 20,000 + EUR 4,200 input VAT, and you sell to VAT-paying clients for EUR 40,000.

• Not a VAT payer: that EUR 4,200 of VAT remains your cost — you do not recover it.
• VAT payer: you charge EUR 8,400 output VAT (21% of EUR 40,000), deduct EUR 4,200 input VAT and remit the difference to VMI — EUR 4,200. Your clients deduct that EUR 8,400 themselves, so their price does not really change.
• Benefit: registration lets you recover EUR 4,200 of input VAT per year.

B2C scenario. You sell a service to a consumer for EUR 100.

• Not a VAT payer: you keep the full EUR 100.
• VAT payer, keeping the price at EUR 100: the "hidden" VAT inside it is EUR 17.36 (100 − 100 / 1.21), which you hand to the state, leaving you EUR 82.64.
• VAT payer, adding VAT on top: the consumer pays EUR 121 — 21% more.

You can see the point: the very same decision brings a benefit in a B2B business and a loss (or a higher price) in a B2C one.

Check your own case

Before registering, calculate the specific impact on your prices:

• With the VAT calculator you will see prices with and without VAT in a minute — it instantly shows how much more expensive you would be for a B2C client, or how much you would recover from purchases.
• Add up your input VAT for the year — if it is large and your clients are VAT payers, registration is probably worth it.
• Verify current rates, thresholds and the registration procedure with VMI or consult an accountant.

Disclaimer: all figures (the EUR 45,000 threshold, the 21% / 12% / 5% VAT rates, the EUR 10,000 EU distance-selling threshold) are indicative and valid for 2026. This is not tax or legal advice — tax rules change, so before making a decision verify current information on the VMI or „Sodra" websites, or consult an accountant.
