4. Two reports, two separate deadlines

The Incomes Register takes two separate reports, and their deadlines get confused. The earnings payment report is filed for each payment within five calendar days of the payment date, and weekends and holidays count towards those five days. The employer's separate report is monthly and is due by the fifth of the following month.

The date that matters is when the pay was paid, not when it was calculated: if payment falls on the last day of a month and the report runs into the next, the clock still starts from the payment day. Where no wages were paid in a month, a regular employer still files a "no wages payable" report; silence counts as a missing report.

5. Who reads the report

The Incomes Register feeds many authorities at once rather than one: Vero reads it for tax, Kela for sickness and parental allowances, pension companies for pension accrual, unemployment funds for entitlement, insurers for accident cover. One incorrect report therefore has consequences in several places.

The effect on the employee is direct: a month reported short can mean a sickness allowance calculated too low, a work condition that appears unmet for unemployment benefit, or a gap in the pension record. Comparing your payslip against the Incomes Register data is the easiest way to catch that in the same month rather than years later.

6. Corrections and the late-filing charge

An incorrect report is not deleted and rewritten; a replacement report is filed and the earlier entry is superseded by reference. Keeping the report references therefore matters: without the reference a correction can register as a second entry, leaving the same wages reported twice.

A report filed late attracts a late-filing charge, and the charge runs per late report: a month caught up in one go can produce many small penalties rather than a single one. Even where payroll is outsourced the obligation stays with the employer — an accountant's delay does not discharge it — so checking that the reports were actually filed belongs on the employer's own routine.

7. What a payslip has to contain

A payslip is not merely a notice of payment but the most frequently produced document of an employment relationship, and its content is set by law. The gross pay, the hours or period worked, the pay basis applied, overtime and supplements, leave information, tax withheld, pension and unemployment insurance deductions, and the net sum paid all have to be visible. It should also be possible to see at what rate the deductions were made.

The readability of a payslip is not a matter of convenience but of legal protection. An employee can only check whether their pay complies with the collective agreement by reading it; and in a residence permit extension the payslip is the most direct evidence that the salary threshold is met. Keeping payslips systematically therefore matters after the employment has ended as well.

8. Why a correction should be made quickly

The mechanics are those of section 6: a replacement report that cites the original takes its place, and a report filed by mistake is cancelled; the original stays visible in the report history. What matters next is speed, because the same data is used by Vero, Kela, pension providers and insurers, and an error can produce different consequences at each of them.

The commonest errors are identifiable: a wrong payment date, an item entered short or in excess, a wrong income type code, and a report sent when no payment was made. Most close with a correction — but the effect on the employee may not be visible immediately. Income reported wrongly, for instance, produces a different picture in a Kela benefit calculation or in the income a person shows in a residence permit application. So telling the employee when a correction is made is the right approach.

9. Reporting benefits in kind and expense reimbursements

Benefits in kind provided alongside salary — phone, car, meals, housing — are reported at their monetary value and most are taxable. Those values are calculated on bases set annually; the company's own estimate is not enough. Failing to report benefits requires correction later, both in the employee's tax calculation and in an inspection of the company.

Expense reimbursements are a different category: mileage on work travel, per diems and repayment of costs incurred for work do not count as pay, but they are still reported and have to stay within the set limits. Anything above the limit is treated as pay. The commonest mistake is a sum that looks like a genuine reimbursement but is paid regularly and without receipts being treated as pay — which leads to retrospective correction for both tax and insurance contributions.

10. Reporting holiday pay, sickness and absences

Annual holiday pay, holiday compensation and the holiday bonus are separate income types and are reported under separate codes. Combining them into one item produces different results both in the employee's tax calculation and at Kela and the pension provider. Sick pay periods, unpaid leave and other absences should likewise appear in the reporting; they affect not only the sum paid but the calculation of the insured period.

In sickness allowance applications to Kela, these reports are used directly. An absence reported incompletely or wrongly delays the employee's application, and correcting it falls to the employer. So during long-term sickness, parental leave and unpaid leave, the accuracy of payslips and reports deserves closer checking than in ordinary months.

11. What payroll records do in an immigration file

In a permit extension, in permanent residence and in a citizenship application, the income record is one of the strongest documents available. An extract from the incomes register shows which employer paid what and when, verified by a third party; that outweighs a contract or a statement. Being able to obtain the extract in one's own name makes preparing the file easier.

So an error in payroll is not only an accounting matter. A period reported short appears as a gap in the work history in a permanent residence application; a wrongly reported figure can produce a finding that the salary threshold was not met. Downloading the extract and checking it before an extension application — and asking the employer to correct any discrepancy — is a step to take before filing rather than after.

12. Who runs payroll: in-house or outsourced?

Running payroll in-house is possible in a small company, but the obligation stays with the company in either case: even where a service is bought in, the company is responsible for the reports being correct and on time. The decision is therefore as much about who is responsible for which step, in writing, as it is about cost.

Where a service is used, three things should be clear in the contract: by what date data reaches the accountant, on what date the reports are filed, and who makes a correction in what time if there is an error. Where payroll is run in-house, what is needed is not software but a calendar: the payment day, the reporting day and the monthly employer report day fixed and owned by one person. In both models the commonest problem comes from data arriving late — and what solves that is an agreed date, not a tool.
