As the buyer of construction services, you must file a report on the contracts you have bought to the Tax Administration.

Private households are not required to file reports on contract details. See instructions for households filing reports on construction work.

What types of work must be reported?

You must report contract details if your company buys some of the following construction services from another company:

You must file a report if the value of a single contract is over €15,000 without VAT. 

You must file a separate report on contract details for each separate agreement. These may be verbal agreements or written agreements.

Remember to submit a report on your employees to the project supervisor

In addition to the contract details, you must also file monthly reports to the site’s project supervisor. You must include in your report all the employees of your company who are working at the shared construction site. 

Contact the project supervisor and ask how you should report this information.

Remember to keep filing reports on employee details as long as the contract is in force.

Frequently asked questions about filing reports

No, it is not enough if you just file a report when the work starts. You must file contract details for every month that is invoiced by the contractor. You must continue reporting even after the work has stopped if the contractor is still sending you invoices.

Enter the start date of construction work as the start date of the contract. If the end date of the contract is not yet known, enter the estimated end date. Give a more exact end date when it is known.

Yes, a contract can cover multiple sites. Every order is treated as a specific contract if a separate payment has been agreed upon. You must file a report if the value of a single contract is over €15,000 without VAT.

The payment may be based on a fixed sum total or on hours worked.

No, you do not need to file the report on contract details if work at the site has been interrupted. File the next report after the work has started again.

Use the new Business ID in your reports after the merger.

If you are submitting corrections to previous reports filed before the merger, use the old Business ID.

You do not need to report later work and renovation done during the warranty period if the contractor has already invoiced the total price of the contract.

You do have to file a report if the contractor invoices the contract’s final instalment after the warranty period has ended.

Any additional work that you buy during the warranty period that is not a part of the original contract is considered a separate agreement. If this additional work exceeds the threshold of €15,000, you must report the contract details.
