Revised tax card: a new rate mid-year

A revised tax card (muutosverokortti) fixes your withholding when income changes during the year. Here is when it pays off and why the new rate can look oddly high or low.

Checked by Radif Partners · Editorial policy · Calculation method

Order a revised tax card (muutosverokortti) when your 2026 income moves well away from what your current card assumes. Take a Helsinki employee whose pay rises in July from €3,000 to €3,800 a month: the old 10.5% card would withhold €4,284 over the year against a tax bill of €5,445, leaving €1,161 short. A revised card recovers that gap from the remaining paychecks, which is why it shows 16.0% rather than the full-year average of 13.5%. Vero estimates the tax for the whole year, subtracts what has already been withheld and spreads the rest over pay still to come. It works in reverse too: when income drops, the rest-of-year rate can fall as low as zero. You can order a new card in MyTax (OmaVero) at any time; it applies until the end of the year or your next change. Rates are rounded up to the half point and capped at 60%. The usual triggers are a raise, a second job, part-time work, unemployment and parental leave.

How the rest-of-year rate is worked out

The card you received in January assumes a whole year of income. A revised rate is not simply the rate for your new annual total. Vero takes three steps: it estimates your full-year tax on the updated income, deducts the tax already withheld at the old rate, and divides what is left by the pay you have still to receive. The result is rounded up to the next half point. The longer you wait after your income changes, the sharper that correction becomes, because every payslip on the wrong rate adds to the gap and fewer paychecks are left to absorb it.

To fill in the request you need an estimate of your total 2026 income, your pay to date and the tax already withheld, all of which appear on your latest payslip. Deductions the automatic card does not know about, such as the household tax credit (kotitalousvähennys), can be added at the same time.

Case 1: a raise in July

A Helsinki employee earns €3,000 a month on a card built for €36,000, with a 10.5% rate. From July the salary is €3,800. Annual income becomes €40,800, taxed at €5,445.

Final tax€5,445€5,445
Shortfall (−) or refund (+)-€1,161€93

On the old card the income limit would eventually be crossed and the additional rate would cover part of the gap. The left column shows the worst case, where the limit was set generously and the additional rate never applies. With the revised card withholding rises immediately and the year ends close to even.

Case 2: a second employer

Two employers is where tax cards go wrong most easily. Each payroll compares only its own payments against the limit, so neither notices that your combined pay has passed it. If the 10.5% rate from a €36,000 main job is also applied to €8,000 of side income, €4,620 is withheld across the year while tax on €44,000 is €6,604: a gap of €1,984. A card calculated on combined income gives 15.5%, applied by both employers. The extra euros are taxed at your marginal rate, not your average one, which is exactly what the old card misses.

Case 3: part-time, unemployment or parental leave

When income drops, the old card over-withholds. Here €3,500 a month falls to €2,000 in August. Income for the year is €34,500 and tax €3,412, but the old 14.0% rate would take €4,830. The first seven months have already covered nearly all of the year’s tax, so the revised rate for the rest of the year is 0.0%. Without the change, €1,418 would sit with Vero until the refund the following year.

Unemployment benefit and parental allowance are taxable, and whoever pays them uses the same tax card. When your salary stops altogether, build the new estimate from wages already received plus the benefits you expect, so the rate works for both.

Timing changes the rate

You might expect a raise that starts late in the year to send the rest-of-year rate soaring. If you revise the card in the same month the raise begins, it does not. Here the same €800 raise starts in three different months.

Helsinki, €3,000 to €3,800 a month, old rate 10.5%
New salary fromAnnual income (new limit)Full-year rateRest-of-year rate
March€44,00015.5%16.0%
July€40,80013.5%16.0%
October€38,40012.0%15.5%

The full-year rate moves a lot, the rest-of-year rate barely at all. Earlier months were withheld correctly for the old salary, so the only gap comes from the higher months, and those are the same months the gap is spread over. What hurts is delay: every higher payslip taxed at the old rate adds to the catch-up. If you know about a raise in advance, revise the card before the first higher payslip.

When to leave the card alone

  • The raise is too small to move your rate by even half a point.
  • Your limit already has room, and only a one-off item such as a bonus goes over it. The additional rate is set high precisely to handle that.
  • Only one or two paydays are left and the difference is a few tens of euros; the assessment will settle it.

For a big change, act at once: each payday on the wrong rate makes the year-end correction steeper. The tax card guide explains the card the revision replaces, the income limit page covers what happens on the old card, and the tax rate calculator has a field for salary already paid.

Frequently asked questions

Why is the rate on my revised tax card higher than my real tax rate?

Because it is also catching up on the months already paid. If too little was withheld early in the year, the gap is collected from the remaining paychecks. In the July raise example the full-year rate would be 13.5%, yet the revised card reads 16.0%. Next January’s automatic card is computed on a whole year again, so the high rate does not stick.

Is it worth revising my tax card for a small pay rise?

Often not. A modest raise is absorbed by the income limit and additional rate: on a €36,000 card in Helsinki the additional rate is 35.5%, which usually withholds enough on the excess. A revision makes sense when the raise moves your rate by half a point or more, or when you want to avoid interest on residual tax. Run the numbers first.

Can I lower my withholding rate if I go part-time?

Yes, and it is usually worth doing. When €3,500 a month drops to €2,000 in August, the old 14.0% card would withhold €4,830 for the year although tax is only €3,412. The revised rate for the remaining months is 0.0%, because the first months already covered almost the whole year’s tax.

I started a second job in Finland: do I need a new tax card?

You need a card that reflects both salaries, because neither employer sees what the other pays. Using a 10.5% card built for €36,000 on an extra €8,000 of side income means €4,620 withheld against tax of €6,604. A revised card on the combined income comes out at 15.5%, and the shortfall never builds up.
