How to use OmaVero in English

OmaVero is reached from vero.fi. You log in with the same credentials you use for banking: your bank identifiers, or a mobile certificate (mobiilivarmenne) if your operator supports one.

The language selector sits at the top of the page. Choosing English switches the interface, and it remembers the choice for future visits.

Two honest caveats. Some letters and decisions are still generated in Finnish or Swedish even when the interface is English, and a few deeper pages fall back to Finnish. If you hit one, the page structure stays the same, so the position of the buttons still tells you where you are.

For a toiminimi, four things matter:

• Filing VAT returns for each tax period
• Applying for and adjusting prepayment tax (ennakkovero)
• Filing the business tax return, Form 5, once a year
• Finding your payment details: the amount due, the due date, and the reference number

Everything else in the service is either informational or does not apply to a small business.

From the front page, open the tax type for VAT (arvonlisävero) and choose the period you are filing for.

You are asked for a small number of figures:

• Tax on domestic sales, broken down by rate. For courier work this is your output VAT at 25.5%.
• Tax deductible for the period. This is your input VAT on business purchases.
• The service calculates the difference, which is what you pay or reclaim.

Before submitting, check the period at the top of the form. Filing correct figures into the wrong period is the most common self-inflicted error, and unpicking it means filing two corrections.

If you had no sales at all, you still submit the return with zeros. Skipping it is treated as a missed filing.

OmaVero shows the amount due, the due date, the bank account for payment, and a reference number.

Use the reference number shown for that specific liability. It is how Vero allocates your payment to the right tax and the right period. A payment sent without it, or with a reference copied from a different tax, can sit unallocated while the original liability continues to accrue late-payment interest.

Pay from your business account if you keep one separate. It makes the bookkeeping obvious later.

You do not grant access inside OmaVero itself. Mandates are managed in the separate Suomi.fi e-Authorizations service, and OmaVero then honours them.

Once a mandate for managing tax affairs is in place, your accountant sees your tax records in OmaVero and can file on your behalf. You keep full access yourself, and you can revoke the mandate at any time.

The mandate covers tax matters only. It does not reach your bank, Kela, or anything else.

Prepayment tax (ennakkovero) is how you pay income tax on business profit through the year instead of in one lump afterwards.

You apply for it in OmaVero by giving an estimate of your annual profit, meaning turnover minus expenses, not turnover. Vero sets instalments based on that estimate and sends you the payment details.

The part people miss is that the estimate can and should be revised. If you registered an estimate of €8,000 in January and by August you can see the year will land closer to €25,000, you change it in OmaVero rather than waiting. The instalments adjust from that point on.

Revising it in both directions is worth doing:

• Too low, and the shortfall arrives as back tax, potentially with interest.
• Too high, and you have lent Vero money for a year at no interest.

An estimate is not a commitment you are held to. It is an input you are expected to keep current.

A few things that regularly trip people up:

• The tax period shown by default is not always the one you mean to file. Check it every time.
• Filing a return is not the same as paying. Both have to happen.
• A return filed on time but paid late still accrues interest on the payment.
• Correcting a filed VAT return means submitting a replacement return for that period, not editing the original.
• Prepayment tax and VAT are separate liabilities with separate reference numbers. Do not merge the payments.
