ID06 and the personnel ledger on Swedish sites: the checks a foreign workforce must pass

The Swedish Tax Agency, Skatteverket, requires the client commissioning a build to register the site and provide an electronic personnel ledger once construction work exceeds four price base amounts. Everyone active on site registers entry and exit, subcontractor staff included. ID06 is the industry card that ties each registration to a verified identity and a valid right to work.

What the Tax Agency asks of the client

The personnel ledger rules sit in Chapter 39 of the Tax Procedures Act (2011:1244) and put the first duty on the byggherre, the client commissioning the work, not on the contractor. Skatteverket requires that client to register the building site with the agency before work starts and to supply the equipment so an electronic ledger can be kept on the premises. The threshold is construction work that can be expected to exceed four price base amounts over the life of the project. The price base amount is set annually, so the threshold has to be recalculated each calendar year rather than carried over from the previous job.

The client may transfer the duties in writing to a contractor commissioned to carry out the whole of the work independently. The transfer must be written. Where the document is missing, Skatteverket still treats the client as responsible. For a foreign main contractor this is the point most often misread: an understanding reached at a site meeting moves nothing.

Every trader operating on the site then keeps its own part of the ledger. That applies to subcontractors at every tier. A staffing supplier placing twelve fitters with a subcontractor counts as active on the site, and each of those twelve appears in the ledger by name, not as a headcount.

Registration happens in immediate connection with starting and finishing work. The ledger must be available to Skatteverket at the site, and the records are kept for two years after the end of the calendar year they relate to. The agency may carry out unannounced inspection visits and is not obliged to give notice.

What the ID06 card actually proves

ID06 is not a government product. It is the construction sector's own system for identification and attendance registration, and most Swedish clients require it by contract. A card is issued only once the holder's identity has been verified against an accepted identity document and the employer is registered in the system. For a third country national the order also needs evidence of a valid right to work in Sweden, meaning a residence and work permit covering the employer and the occupation the permit was granted for.

The link between the two is straightforward. The ledger is the legal requirement, and ID06 is the tool the industry uses to satisfy it while controlling who passes the gate. When a card is blocked, for example because a work permit has expired, the holder drops out of gate access that same day. Plan permit renewals against the card's validity rather than against the end date in the employment contract.

The cost, the language rule and the usual failure

Skatteverket charges a control fee under Chapter 50 of the same act where the ledger falls short: the site was never registered, no ledger is kept, or a person active on site does not appear in it. The fee has two parts, one for the shortcoming itself and one for each person missing from the ledger. Both are tied to the price base amount and therefore move each year, and the agency charges a higher amount where the same breach recurs within a year of an earlier decision. Check the current year's figures with Skatteverket before pricing the risk, because the number follows the base amount.

The Work Environment Authority, Arbetsmiljöverket, adds a parallel duty that has nothing to do with tax. A worker must receive instructions and safety information in a language he or she understands. A briefing held in Swedish for a crew speaking Nepali or Serbian does not meet that requirement, and the gap shows up quickly in an inspection when nobody can say where the assembly point is. Translate safety rounds, work preparations and emergency routines before the first shift, and record that the briefing took place.

The costliest failure in practice sits at the seam between tiers. The main contractor registers its own staff correctly while a subcontractor's hired fitters work three days without appearing in the ledger, because neither party thought the registration was theirs. An inspection then produces a fee for each unregistered person, and the client starts questioning the whole supply chain at the same time. Write into the contract who keeps the ledger for each tier, and reconcile that list against the gate log every week.

The right to work underpins all of it, and right to work verification inside the EU sets out what an employer should see and retain before anyone reaches the gate. For third country nationals the permit itself governs what the card can carry, and the mechanics of the combined document are in the single permit directive explained. Processing time decides the start date, and the corridor by corridor comparison shows how far ahead the order has to be placed.

Sweden treats two checks as one door: the Tax Agency ledger answers who was on site, and ID06 answers whether they were entitled to be. A foreign workforce clears both when permits, cards and registration run on the same schedule as the material deliveries. To work through a specific crew ahead of a build start, the detail sits with our employer team.
