A tulorekisteri ilmoitus must be submitted electronically to the Incomes Register, typically as a palkkatietoilmoitus, within a few calendar days of the payment date. Verohallinto, Tulorekisteri and Suomi.fi govern how you submit, correct and receive notifications about these reports, and getting the process wrong carries real financial risk. This guide walks you through report types, submission methods, corrections and deadlines so your payroll runs stay compliant.
TL;DR:
- Most reporting errors are administrative, such as incorrect identity codes or payment dates, which can be caught early with a pre-flight checklist.
- Reporting deadlines are five days after payment, but submitting reports up to 45 days in advance reduces errors and last-minute corrections.
- Corrections require either replacing the entire report for data errors or nullifying and resubmitting for incorrect identifiers, with responsibility fully on the employer.
- Access to the Incomes Register is managed via Suomi.fi authorizations, which must be regularly updated and monitored to ensure timely notifications.
- Outsourcing tulorekisteri reporting to specialized providers can prevent recurring mistakes and streamline compliance, especially for organizations with high volumes or correction issues.

What to report: choosing the right income register notification
Three report types cover almost every payment you make as an employer, and picking the wrong one is one of the more common ways a tulorekisteri ilmoittaminen process goes wrong.
The palkkatietoilmoitus (earnings payment report) covers wages, holiday pay, fringe benefits, and mileage reimbursements. It must be submitted separately for each income earner, for each payment date. If you pay ten employees on the same day, you file ten reports, or one batch submission containing ten earner-level entries.
The työnantajan erillisilmoitus (employer's separate report) handles employer contributions, such as health insurance contributions, and is also how you notify Verohallinto that no wages were paid in a given month.
The etuustietoilmoitus (benefit payment report) applies to organisations paying statutory or voluntary benefits, such as pension providers or insurers, rather than typical wage payers.
Common payroll items map like this:
- Monthly salary, overtime, bonuses → palkkatietoilmoitus
- Tax-free mileage and expense reimbursements → palkkatietoilmoitus (specific income types)
- Fringe benefits (company car, meal vouchers) → palkkatietoilmoitus
- Employer's health insurance contribution → työnantajan erillisilmoitus
- No wages paid this period → työnantajan erillisilmoitus (nil notification)
- Pension or insurance benefit payments → etuustietoilmoitus
Detailed field-level guidance for each wage type sits in Verohallinto's wages reporting documentation, which is worth bookmarking if your payroll includes anything beyond standard salary.
How do you submit a tulorekisteri ilmoitus?
You have two practical routes: the free e-service, or an API integration through your payroll software. Larger employers with recurring monthly runs tend to favour integration once volumes justify the setup work; smaller employers often manage comfortably through the e-service alone.
Before you open the e-service, gather everything you need. The earnings payment report guidance confirms you cannot save an unfinished report as a draft, so incomplete data means starting over.
Have ready:
- The income earner's personal identity code or Business ID
- Payment date and pay period
- Gross amount, income type, and applicable tax withholding
- Any fringe benefit or reimbursement codes
- Employer's Business ID and authorised user credentials
The submission sequence itself runs predictably:
- Log in via Suomi.fi authentication
- Select the correct organisation if you manage several
- Choose the report type (palkkatietoilmoitus, työnantajan erillisilmoitus, or etuustietoilmoitus)
- Enter earner and payment details, checking each field against your payroll run
- Submit and note the confirmation reference number
If you submit through an accounting system rather than the e-service, your software needs a valid certificate to authenticate with the Incomes Register's API. Certificates expire and need periodic renewal, so build that into your annual compliance calendar rather than discovering it mid-payroll-run.
Pro Tip: You can submit reports in advance before the payment date. Employers running fixed monthly payroll schedules often report a few days early rather than scrambling within the standard reporting window, which gives you breathing room if something needs a quick fix.
Correcting errors: replacement report or nullification?
The employer, not the income earner and not the Incomes Register itself, is always responsible for correcting mistakes. The Verohallinto guidance for payers is explicit on this point: nobody else can fix your data for you.
Which correction method depends on what went wrong:
- Replacement report: use this for data errors, such as a wrong gross amount, an incorrect tax withholding figure, or a missing benefit code. The replacement overwrites the original entry entirely, so it must contain all correct fields, not just the corrected one.
- Nullification: use this when the fundamental identifiers are wrong, such as the wrong income earner, the wrong payment date, or a duplicate submission. Nullifying removes the report from the register; you then submit a fresh, correct report if the payment was genuine.
Before correcting anything, check the original submission in the e-service history and read any error message carefully. A rejected field often points straight to the problem.
A simple example: if you entered €2,400 instead of €2,040 for gross salary, submit a replacement report with the correct amount. If you accidentally filed the report under the wrong employee's identity code, nullify it and file a new report under the correct person.
Deadlines, advance reporting and penalties
The standard deadline is five calendar days from the payment date, with limited exceptions for certain in-kind benefits and specific household employer situations. Miss it, and you risk an ilmoituspuutemaksu, a penalty fee that Verohallinto can apply for late or incorrect reporting.
Reporting window in practice: you can file as early as 45 days before payment, but no later than five calendar days after it. That forty-five-day window exists precisely so payroll teams with predictable pay dates can report ahead of time rather than working against the clock.
Verohallinto treats accurate, timely reporting as a legal obligation, not a courtesy. Penalty amounts vary depending on the nature of the violation and the payer's reporting history, and authorities tend to intervene more firmly where errors repeat rather than for a single isolated slip. Building advance reporting into your payroll calendar is the simplest defence against ever testing that threshold.
Authorisations and Suomi.fi messages: who sees what
Access to the Incomes Register runs through Suomi.fi authorisations, which means someone in your organisation, typically a company director or an appointed accountant, must grant e-service access to whoever handles your payroll reporting.
Once a user identifies themselves in the e-service, Suomi.fi messages activate automatically, replacing postal correspondence with electronic notifications and documents delivered straight to the Suomi.fi inbox. The message archive holds documents dating back to 2022.
Run through this checklist to avoid missed notifications:
- Confirm which staff member holds active Suomi.fi authorisation for your organisation
- Check that the authorised person actually logs into their Suomi.fi inbox regularly, not just the payroll system
- Update authorisations promptly when payroll staff change roles or leave
- If you outsource payroll, confirm whether your accounting partner or your own team receives the notifications
Common reporting mistakes and how to avoid them
Most errors that trigger a replacement report or a penalty warning are administrative rather than complex tax mistakes: a transposed identity code, a payment date one day off, a missing income type code. A short reconciliation step, matching payroll run totals against report figures before submission, catches most of these errors before they reach Verohallinto.
Build a pre-flight checklist matching the register's required fields: identity code, payment date, gross amount, withholding, and benefit codes. Run it every single payroll cycle, not just when something feels unusual.
Keep certificate renewals and Suomi.fi authorisations on a recurring calendar reminder rather than reacting when access fails mid-submission. Document every correction, both the original error and the fix, so you have a clear trail if Verohallinto ever queries repeated corrections.
Pro Tip: If your organisation submits several reports each month and corrections keep recurring, that pattern usually signals a process gap rather than bad luck, and it's often the point at which outsourcing to an accounting partner becomes the more efficient choice.
What actually matters when reporting to the income register
Most guidance on tulorekisteri ilmoittaminen focuses on the mechanics of filling in fields, and that's useful, but it misses the bigger issue: accuracy at first submission matters more than speed. Because the register feeds data in real time to close to 400 authorised public bodies, a wrong figure doesn't just sit in a queue waiting to be caught. It can ripple into a benefit calculation or a tax assessment before you've noticed the mistake yourself.
The conventional advice tells employers to "report on time." That's necessary but insufficient. The five-day deadline is a floor, not a target. Employers who treat the 45-day advance window as their default, rather than an emergency backup, give themselves room to catch errors before they become corrections. Reactive payroll teams, filing on day four or five under pressure, are the ones who end up nullifying reports and explaining discrepancies to Verohallinto.
If there's one priority worth adopting above all others, it's building the reconciliation habit before submission, not after. Corrections are manageable. Repeated corrections are what draw scrutiny.

Let Finovate handle your tulorekisteri reporting
There are services that give Finnish employers a way to hand off tulorekisteri reporting entirely, rather than building internal checklists and hoping certificates never lapse at the wrong moment. Such payroll teams manage submissions, corrections, authorisation setup, and ongoing monitoring of Suomi.fi notifications, so nothing sits unread while a deadline passes.
If you're weighing up whether to outsource, consider contacting a provider with your current payroll schedule, employee count, and whether you're handling wages, employer contributions, or benefit payments. That's enough information to scope the work. Businesses managing correction backlogs or repeated ilmoituspuutemaksu warnings tend to see the fastest improvement once reporting moves to a dedicated team.
