What We Do

Specialist iXBRL tagging. Nothing else. Serving Finnish listed companies, commercial filers and accounting firms.

Finnish iXBRL regulation now spans three separate mandates — ESEF for listed companies since 2021, the PRH commercial filing rollout from 2027, and mandatory audit assurance since December 2023. XBRTags handles all three under one fully managed service.

No software to licence. No taxonomy training for your team. No per-revision charges. You send the annual report — we return a validated, gateway-tested iXBRL file with audit-ready documentation. Most clients receive delivery within seven business days.

Is your company ready for the 2027 mandate?

From 2027, most Finnish companies required to appoint a statutory auditor must file financial statements in iXBRL via ytj.fi. The threshold is low — most companies with material business activity will be in scope. Run a dry-run now and know your readiness before it's mandatory.

Client Feedback

Mikko L.

CFO, Helsinki-listed industrial group

ESEF iXBRL

"The taxonomy update from FY 2023 to FY 2024 changed how our intangibles note was tagged. XBRTags handled it without us needing to know anything about it. The file was with Nasdaq CSF three days ahead of deadline."

Sanna L.

Partner, Helsinki-based audit firm

Multi-client partner

"We have eleven listed clients on Nasdaq Helsinki. Since partnering with XBRtags, our team submits the files and XBRTags returns validated packages. It's freed up time we now use on higher-value work."

Tiina M.

Finance Controller, Tampere manufacturing

PRH dry-run filing

"We ran a dry-run PRH iXBRL filing for FY 2024. XBRTags identified three areas where our management report structure needed to change. Invaluable preparation for the 2027 mandate."

3 Business Days — Standard

Competitors charge premium for 3-day delivery. We include it on every file.
