For LAC to handle your company's taxes, payroll, and the reads that make both verifiable, your company grants Suomi.fi mandates to our filing entity. Grant the **full list below in one wizard pass** — it takes about five minutes, selecting everything at once means you never have to come back for a missing authorisation, and nothing is ever filed without a human review on our side. The Suomi.fi interface is shown in Finnish below; the flow is identical in the English UI. ## What you need * The right to grant mandates for your company — typically you're the CEO, or hold a registered right to represent the company alone. * Finnish online banking credentials, mobile certificate, or a certificate card for identification. ## Steps Go to [suomi.fi/e-authorizations](https://www.suomi.fi/e-authorizations) (Finnish: [suomi.fi/valtuudet](https://www.suomi.fi/valtuudet)), press **Identify yourself**, sign in, and choose to act on behalf of your company. You land on **Yrityksen valtuudet** (Company mandates). Press **Anna tai pyydä valtuuksia** → **Anna valtuuksia** (Grant mandates). Suomi.fi company mandates page (Yrityksen valtuudet) with the granted-mandates list and the grant-or-request button Step 1/7 asks for the mandate type. Pick **Asiointivaltuus** (mandate for transactions) — you're authorising an accounting firm to act on the company's behalf. Suomi.fi grant-mandates step 1 of 7: mandate type selection with Asiointivaltuus selected Step 2/7 (**Osapuolet**, parties): under *Lisää valtuutetut*, search by business ID and add: * **Name:** Bloom Systems Oy (operating as Last Accounting Company) * **Business ID (Y-tunnus):** 3616618-4 Suomi.fi grant-mandates step 2 of 7: Bloom Systems Oy 3616618-4 added as the authorised party Step 3/7 (**Valtuusasiat**): search and tick **every theme below** (the English title is followed by the exact Finnish title shown when your Suomi.fi interface is in Finnish). If the wizard is in Finnish, search using a distinctive word copied verbatim from the Finnish line instead of translating the English title yourself: 1. **Maintaining information on unemployment insurance contributions**
Työttömyysvakuutusmaksutietojen ylläpito — unemployment-insurance contributions and training compensations. 2. **Management of electronic messages**
Sähköisten viestien hallinnointi — authority message settings, reading, and sending messages for your company. 3. **Managing of tax affairs**
Veroasioiden hoito — VAT returns, tax-account reads, and the other Vero work LAC prepares for you. 4. **Ordering and retrieving records related to the payer’s earnings payment data**
Maksajan palkkatietoihin liittyvien aineistojen tilaaminen ja noutaminen — the official machine-readable record of payroll data filed for you. 5. **Processing of log, interface and report data related to income data**
Tulotietoihin liittyvien loki-, rajapinta- ja ilmoitustietojen käsittely 6. **Processing salary information**
Palkkatietojen käsittely 7. **Processing TyEL insurance and payment information**
TyEL-vakuutus- ja -maksutietojen käsittely 8. **Processing TyEL insurance, payment and earnings information**
TyEL-vakuutus-, maksu- ja ansiotietojen käsittely 9. **Reporting earnings payment data**
Palkkatietojen ilmoittaminen — payroll reporting to the Incomes Register. 10. **Reporting, updating, and retrieving tax information via the interface**
Verotukseen liittyvien tietojen ilmoittaminen, päivittäminen ja hakeminen rajapinnan kautta 11. **Submitting an interface application related to taxation, income and credit information and ordering certificates**
Verotukseen, tulotietoihin ja luottotietoihin liittyvän rajapintahakemuksen tekeminen ja varmenteiden tilaaminen The full list lets LAC resolve tax, payroll, pension, unemployment-insurance, message, and records matters for you without another Suomi.fi visit later. Every mandate is read or filing authority only — money never moves without you, and filings always pass a human review at LAC. Suomi.fi grant-mandates step 3 of 7: mandate theme search with Palkkatietojen ilmoittaminen selected Step 4/7 (**Valitut valtuusasiat**) lists what you picked — check all eleven themes are there. Leave the *valtuuden tarkenne* (mandate specifier) toggle off. Suomi.fi grant-mandates step 4 of 7: selected mandate themes review Step 5/7 (**Valtuuden vahvistajat**): if you can represent the company alone, Suomi.fi says so — just continue. (If your trade register entry requires shared representation, Suomi.fi routes you to co-confirmation here.) Suomi.fi grant-mandates step 5 of 7: mandate confirmers, confirmable alone Step 6/7 (**Voimassaolo**): set the validity period. We suggest the maximum, 25 years — you can revoke the mandate at any time. Suomi.fi grant-mandates step 6 of 7: validity period start and end dates Step 7/7 (**Yhteenveto ja vahvistus**): check the summary — assignee Bloom Systems Oy 3616618-4, your themes, the validity — and press **Vahvista** (Confirm). Suomi.fi grant-mandates step 7 of 7: summary and confirmation with selected mandate themes listed Suomi.fi confirmation page after granting the mandates The grants now show under **Annetut valtuudet** (Granted mandates). Back in the [LAC portal](https://app.lastaccountingcompany.com), press **I have granted these mandates** on the Suomi.fi onboarding step. We verify the mandate with the authorities before anything is filed. Suomi.fi company mandates page showing Bloom Systems Oy with granted mandates ## Revoking You stay in control: the mandate can be revoked at any time in Suomi.fi e-Authorizations under **Annetut valtuudet** (Granted mandates). If you revoke it, LAC can no longer file on your behalf and we'll reach out about next steps. ## Trouble? If Suomi.fi says you can't grant mandates alone (for example the trade register lists shared representation), Suomi.fi offers a **mandate application** flow, or another representative can co-confirm at step 5. Message us in the portal chat and we'll walk it through with you.
