What changed on 1 May
Regeringen announced on 30 April 2026 that tax on petrol and diesel is being reduced for the period 1 May to 30 September 2026.
The stated purpose is to soften the effect of higher fuel prices on households and companies after disruption in global energy markets.
The official household-sized estimate is simple: if the full tax cut reaches the final customer, petrol should be roughly SEK 1 per litre lower than it otherwise would have been, and diesel roughly SEK 0.40 per litre lower.
That wording matters. A tax cut can be hidden by oil-price moves, exchange rates, wholesale costs, and local station pricing.
The tax-table check
Skatteverket's fuel-tax tables show the mechanics behind the headline. For motor petrol in environmental class 1, the total tax was SEK 4.79 per litre from January through April 2026 and is SEK 3.97 per litre from May through September.
For diesel in environmental class 1, the total tax was SEK 3.961 per litre before May and is SEK 3.642 per litre from May through September.
Those differences are before the real-world noise of pump prices. The diesel tax-table drop is about SEK 0.319 per litre before VAT, which matches the government's roughly SEK 0.40 per litre consumer estimate once VAT is included.
The petrol difference is about SEK 0.82 before VAT, or roughly SEK 1 after VAT.
| Fill-up | Petrol estimate | Diesel estimate |
|---|---|---|
| 40 litres | About SEK 40 lower | About SEK 16 lower |
| 60 litres | About SEK 60 lower | About SEK 24 lower |
| 100 litres in a month | About SEK 100 lower | About SEK 40 lower |
How households should use it
- Compare litres, not total kronor. A larger tank or extra trips can erase the saving even if the litre price is lower.
- Use the same station or route. Station-level differences can be bigger than the diesel tax cut.
- Keep fuel separate from food and electricity. The last month already had separate policy changes and price moves, so avoid mixing them into one "cheaper month" assumption.
- Review again before October. The cut is temporary, so a commute-heavy budget should not treat it as a permanent reduction.
For a household that drives 120 litres of petrol per month, the full pass-through estimate is about SEK 120 per month. For 120 litres of diesel, it is about SEK 48.
Those amounts are useful, but they are not large enough to justify ignoring insurance, parking, repairs, loan payments, or route changes.
If fuel is part of a tight month, add the saving as a separate note when using the income impact calculator. Parents can keep commute costs separate from benefit choices in the parental benefit calculator and leave planner.
The practical test is boring and useful: record litres, price per litre, and station for the next two or three fill-ups. If the full cut appears, decide where that smaller monthly saving goes before it disappears into normal spending.
