If you are budgeting a highly skilled migrant hire for early 2027, assume the gross salary you commit to in Q1 is higher than the one you could commit to today, and that the difference is not symbolic. The hsm salary threshold employer obligation resets on 1 January every year, the IND publishes the new figures in the autumn, and from that date the new amount applies to every new application. Your existing permits are not retroactively broken, but your renewals, your extensions and anything still sitting in the IND queue behave differently from each other, which is where most payroll surprises come from.

The cheaper comparison is not always "hire in Q4 2026". Sometimes it is, and the arithmetic below shows when. But the bigger cost for most employers is not the new hire at all. It is the three or four people already on your payroll who were comfortably above the line in 2024 and have not had a market-rate adjustment since.

Below is the employer-side version of the reset: how the indexation is calculated, which of your current staff are exposed, how renewals and new applications diverge, and what a Q4 offer actually buys you compared with a Q1 one.

The number that resets every January, and who actually pays for it

Three things are worth being precise about, because HR teams routinely get one of them wrong.

It is a gross monthly salary criterion, not an annual one. The IND tests the gross monthly wage excluding holiday allowance (vakantiegeld). An employee on a package that averages out fine across the year can still fail the monthly test. Thirteenth-month payments, bonuses and variable pay generally do not count toward it, because the criterion wants a fixed, contractual, monthly amount paid into a Dutch bank account.

There are separate figures by age bracket and category. The main split is the under-30 rate and the 30-and-over rate, with a lower, separate amount for recent graduates of the orientation year (zoekjaar) and for people who graduated from a Dutch institution. Those brackets move independently each year, and an employee who crosses their 30th birthday mid-permit does not jump to the higher bracket for the remainder of that permit. The bracket is fixed at the moment of application.

The employer is the applicant. As a recognised sponsor (erkend referent), you file, you pay the application fee, and you carry the duty to inform the IND when something material changes. The employee does not have a parallel route to fix a shortfall. If the salary drops below their applicable criterion, that is your reporting obligation and your compliance exposure, not theirs. The duties that come with the status are covered in the guide to becoming an IND recognised sponsor, and they do not get lighter after the first year.

The criterion is per-employee, fixed at application, and indexed for everyone you hire after 1 January.

The indexation follows the development of Dutch contractual wages (the CAO wage index) as published by CBS, applied by ministerial regulation. It is mechanical, not discretionary, and that mechanism is exactly why employers underestimate it.

Dutch collective labour agreements in recent bargaining rounds delivered unusually large nominal increases. Those negotiated rises feed into the index that sets the IND salary threshold 2027 Netherlands figures. So the reset is not tracking inflation as you experience it in 2026; it is tracking wage settlements that were signed earlier and are still working through the data.

The practical effect: if you have been budgeting a flat 2 to 3 percent uplift for threshold movement because that is what it used to be, the planning number deserves revisiting. Do not take a figure from a blog, including this one. The official amounts appear on the IND's salary criteria page, usually published in the final weeks of the year, and the candidate-side breakdown of what changes on 1 January tracks them as they land. Build your budget around a range, confirm it in December, and do not sign offers for Q1 start dates with a number you pulled from a 2026 template.

One more thing that moves alongside it: the 30% ruling salary requirement has its own threshold and its own indexation, and it is not the same number as the HSM criterion. An offer can clear the HSM line and fail the ruling's test, which changes the employee's net position without changing yours. The eligibility mechanics sit in the 30% ruling guide, and it is worth knowing which number you are quoting when a candidate asks about take-home pay.

The payroll audit: which current HSM employees fall below the new line

Before you model new hires, find out what your current book looks like. The audit takes an afternoon and it is the highest-value hour in this whole exercise.

Pull every active HSM permit holder and, for each one, note four fields:

Then sort by the gap between current salary and the criterion you expect for 2027. The people at the top of that list are usually not recent hires. Recent hires were priced against a recent threshold. The exposure concentrates in two groups: employees hired three or more years ago whose salary has moved by less than the cumulative indexation, and employees who were hired under the under-30 bracket and are approaching a renewal in which the 30-and-over figure will apply.

That second group is the one that catches people out. An employee hired at 28 under the lower bracket, renewing at 31, is tested against the higher bracket at the new indexed level. The jump between "what we have been paying" and "what the renewal requires" can be substantial, and it arrives as a single step rather than a glide. The renewal-side view of this, from the employee's perspective, is in the highly skilled migrant permit renewal checklist. The numbers are the same, but the person reading that page is the one who will raise it with you in a one-to-one.

The threshold applies to both, but the moment it bites is different, and the difference drives your sequencing.

For a new application, the criterion in force on the date the IND receives a complete application is the one that applies. File on 18 December 2026 and the 2026 figure governs. File on 5 January 2027 and the 2027 figure governs. The start date on the contract matters less than the filing date, which is why some employers file in December for a February or March start. The contract has to be genuine and the salary has to be real from day one of employment, but the criterion is locked at filing.

For an extension, you are tested against the criterion in force at the time of the extension application, in the bracket that applies then. This is the part employers describe as unfair, and it is simply how indexation works: a permit does not carry its original number forever. If the employee's salary has not kept pace, the extension is the point at which you either raise the salary or lose the permit.

For a change of role or a salary change mid-permit, your reporting duty applies. A promotion that increases salary is straightforward. A move to part-time hours is not, because the monthly criterion is a monthly amount, not an hourly rate. A four-day week at the same annual level fails if the monthly gross drops below the line. The mechanics of raises, promotions and reduced hours under an HSM permit are set out in the post on raises and promotions for highly skilled migrants.

There is a second-order effect here that affects hiring, not compliance. Candidates currently on an HSM permit elsewhere who want to move to you are also exposed to the reset, because a change of employer means a new application. Someone whose current salary clears the 2026 line but not the 2027 one becomes harder to hire in January than in November, at the same salary.

Model it as two scenarios for the same role, not as "hire now or hire later".

Scenario A: offer accepted and application filed in December 2026. You lock the 2026 criterion for that application. Your gross monthly commitment is the 2026 figure plus whatever premium the market demands for the role. The application fee, the recognised sponsor administration and the relocation support are unchanged by timing; those numbers sit in the breakdown of the cost of visa sponsorship in the Netherlands. What you have bought is a lower floor for as long as that permit runs.

Scenario B: offer accepted in January or February 2027. The 2027 criterion applies. On a single hire, the delta on gross monthly salary is modest in absolute terms. Multiply it by twelve months, add 8% holiday allowance, add employer social charges and pension, and it becomes a real line in a headcount budget. Over a permit cycle it compounds, because every subsequent raise is calculated from a higher base.

The honest counterweight: rushing a hire to beat the reset is a bad trade if it means hiring the wrong person. A mediocre senior engineer at the 2026 floor costs more over two years than a strong one at the 2027 floor. The timing argument only works where you already know the role, have a shortlist, and are waiting on a budget sign-off that could reasonably happen in November instead of February.

Where the hire before salary threshold increase logic genuinely holds:

Where it does not hold: a role you have not scoped, a candidate you have not met, or a salary band that sits 30% above the criterion anyway. In that last case the reset changes nothing about your offer and you should stop optimising for it.

The failure mode worth naming: an offer drafted in November against the 2026 figure, with a filing date that slips into January because a document was missing. The IND does not treat an incomplete application as filed. A missing legalised diploma, an unsigned employment contract, an apostille that took five weeks, and your December filing becomes a January one against a higher criterion.

Two protections. First, treat the application file as the deliverable, not the signed offer. Know which documents the candidate still needs to obtain from abroad before you promise a start date, and remember that document legalisation in some countries runs to months, not weeks. Second, write the offer so the salary clears the expected 2027 figure with room, even if you intend to file in December. If the filing slips, the offer survives.

The candidate-side checklist of what makes an offer eligible, which is useful to read before you draft one, is in is your highly skilled migrant offer eligible. Salary is the number everyone checks. The contract type, the duration, the Dutch bank account requirement and the role's genuine skill level are the parts that get offers rejected after the salary has been agreed.

For current staff who sit below the expected 2027 line, you have three options and only one of them is good.

Raise them in advance, as a planned compensation adjustment in the normal review cycle, and frame it as what it is: an indexation correction. It costs the same as doing it under duress at renewal, and it does not turn a retention conversation into a compliance conversation. An employee who learns from their own research that their permit renewal is at risk because of their salary will start looking, and they are easy to hire away.

Raise them at renewal, which works mechanically but concentrates the cost into the month you can least control and gives the employee a reason to negotiate from a position of leverage.

Do nothing and discover at renewal that the gap is larger than you can approve. This is the one that ends with a permit not extended and a vacancy you did not plan for.

For budgeting, a defensible approach is to take your audit list, apply a planning uplift to each person's criterion, calculate the shortfall, and add employer charges on top. Hold the total as a contingency line rather than distributing it, then confirm against the published IND figures in December and release what you do not need. The full picture of what sponsorship costs across fees, admin and salary floor sits alongside this in your headcount model, not as a separate exercise.

Confirm the current criterion and the bracket that applies to your candidate, check that the gross monthly figure excluding holiday allowance clears the expected 2027 number with margin, and know which documents are still outstanding before you commit to a filing date. If the role is approved and the only thing missing is candidates, a Featured Job Post is €99 per 30-day listing, pinned at the top of arrowlancer.com/jobs with a Featured badge, in front of people already searching for visa-sponsored roles. That buys you weeks of pipeline inside the current threshold window, which is the part of the timing you can still influence.
