Personalliggare and ID06 on Site: What the Rules Are

A personalliggare is an electronic staff register that most construction sites in Sweden must keep, and ID06 is the industry card-and-reader system most firms use to run it. Together, personalliggare and ID06 answer the one question the Swedish Tax Agency (Skatteverket) can turn up unannounced to ask: exactly who is working on this site right now, and are they declared? Everyone on a covered site logs their arrival and departure, in real time, in a register that has to be available on site for inspection. It is not a health-and-safety sign-in sheet and it is not optional paperwork — it is a tax-enforcement tool with fixed fines attached, and on a byggarbetsplats the client and each contractor carry different, specific duties for keeping it right.

What a personalliggare actually is, and why it exists

Sweden brought the construction-site staff register in to attack undeclared labour — cash workers who never appear on any payroll. The register is deliberately dumb and deliberately live: a running list of every person present, stamped in when they start and out when they finish, so an inspector standing on site can count heads and match them against who is logged. If a person is on the scaffold but not in the register, that gap is the whole point of the law.

The register has to be electronic, kept available on or near the site, and it records each individual’s presence for each firm operating there. It is not a timesheet for payroll and it is not a competence check. Its single job is presence: who, and when.

Where the rules apply: the value threshold

The obligation is not triggered by the type of work but by its size. Construction activity expected to cost more than four price base amounts (prisbasbelopp) excluding VAT falls under the rules. The number of price base amounts is stable; the kronor value of one prisbasbelopp is set each year, so the cash threshold moves. Check the current figure at skatteverket.se before you assume a small job is exempt.

Below the threshold, and for a private individual having limited work done on their own home, the personalliggare duty generally does not bite. That exemption is narrower than people hope, so do not build a project plan around it without confirming the specifics for your job.

Who is responsible: byggherre, main contractor, each firm

The duties split three ways, and mixing them up is where sites get caught.

• The client (byggherre) must notify Skatteverket before work starts and make the electronic register equipment available on the site. The client can transfer these obligations to a contractor who runs the works, but only through a written agreement — a handshake does not move the duty.
• Each company on site keeps its own register of its own people. Your firm is responsible for your staff being logged, even when someone else supplies the equipment.
• Each individual registers without delay when they start and finish work on site. “I’ll do it at lunch” is already a breach.

The self-employed running the whole job themselves have lighter duties around registering their own presence, but the moment they bring anyone else on, the full machinery applies.

What ID06 is, and why it is not the government

Here is the point everyone gets wrong: the law requires a personalliggare; it does not require ID06. ID06 is a private industry standard, run by a company, that packages an ID card, a competence database, site access control and an electronic staff register into one system. It is the dominant way to meet the legal duty, and most large clients require it contractually — but that is a commercial requirement from the client, not a statutory one from Skatteverket.

The practical consequence: you can be fully legal without ID06 if your electronic register meets the rules, but you may not win the contract without it, because the main contractor writes ID06 into the terms. Read your site rules. If the client mandates ID06, that is the standard you order cards and readers against, separate from the legal minimum.

How registration works day to day

On a covered site the flow is simple and unforgiving:

• Every worker carries a valid ID card (an ID06 card on an ID06 site) that identifies them and their employer.
• They tag in at the reader when they arrive and tag out when they leave, every day, without delay.
• The register updates live and must be available for Skatteverket to inspect on the spot.
• Records are retained for a set period after the work ends, so an inspection months later can still be answered.

The failure modes are boring and common: a worker forgets to tag out and shows as present overnight, a subcontractor’s new starter has no card, a visiting delivery driver is unsure whether they count. Build tagging in and out into the same habit as putting on a hard hat and most of the risk disappears.

What Skatteverket checks, and what it costs to get wrong

Inspections (kontrollbesök) are unannounced by design. An inspector arrives, counts the people working, and cross-checks them against the register. If the register is missing, not up to date, or does not have someone who is clearly on site, they issue a control fee (kontrollavgift).

The fines have two parts: a fixed charge for not keeping a compliant register at all, plus a per-person charge for each individual who should be in it and is not. Both amounts are tied to the price base amount, so they move each year — do not quote a friend’s number from two years ago. Check the current control-fee amounts at skatteverket.se. Repeat breaches can be charged again. The sting is that the per-person fee scales: a big crew of unregistered people on one visit is an expensive afternoon.

If you have never met this: the equivalent elsewhere

Outside Sweden there is no direct copy, because the personalliggare is a tax instrument, not a safety one. The nearest reference points do different jobs:

So if you are used to a fire-register clipboard and a competence card, the Swedish system will feel familiar in shape but strange in purpose. The register is not there to get you out of the building in a fire; it is there so the state can see who is being paid.

Keeping your own record alongside the register

The legal register belongs to the site and, on an ID06 site, sits inside ID06. That is not the same as knowing your own hours. A common mess: the personalliggare says your fitter was on site, your payroll says something else, and nobody can reconcile them at month end.

Running your own attendance record in parallel closes that gap. A geofenced time clock in OdinTask logs when your people arrive at and leave a job, works offline when the site has no signal and syncs when it does, and exports to payroll. It does not replace ID06 on a site that mandates it — the legal register is still the legal register — but it gives you an independent, timestamped record of your own crew that you can check against the site register and against the invoice. When the two disagree, you find out from your own data, not from Skatteverket.

Getting it right without drama

• Confirm early whether the job is over the four price base amount threshold and who the byggherre has named as responsible.
• Get the transfer of the client’s duties in writing if it lands on you.
• Order the right cards for the site standard — ID06 if the client requires it — before the first worker turns up.
• Make tag-in and tag-out a non-negotiable daily habit for everyone, including short visits and new subcontractors.
• Keep your own attendance record so payroll, the invoice and the register all tell the same story.

None of this is clever. It is the same lesson as ROT paperwork or an egenkontroll: the rule is simple, the fine is fixed, and the only thing that goes wrong is the habit slipping on a busy day.
