Road tax 2026/27

Mercedes-Benz SLK road tax in 2026/27

Road tax (VED) on a Mercedes-Benz SLK in 2026/27 depends on when it was first registered. One first registered between 1 March 2001 and 31 March 2017 pays by CO2 band: across the 126 versions in the Vehicle Certification Agency's CO2 database from 2001 to 2016, that is £35 (band C) to £790 (band M) for 12 months, most often £445 (band K). One first registered from 1 April 2017 pays the £200 standard rate each year after its first (plus £440 a year in years 2 to 6 if its list price was over £40,000, or £50,000 for an electric car registered from 1 April 2025). Cars first registered before March 2001 pay by engine size: £230 up to 1,549cc, £375 above.

Which Mercedes-Benz SLK is cheapest to tax

3% of the Mercedes-Benz SLK versions sold between 2001 and 2016 pay less than the £200 a newer car pays, because their CO2 figure puts them in a band below it. The cheapest listed was the SLK-Class SLK 250 d with 17'' & 18'' rear wheels ECO Start/Stop (2143cc diesel, A9) at 114g/km (£35); the dearest the SLK-Class Model Year 2010 SLK 55 AMG with 245/40 17" or 245/35 18" rear wheels (5439cc petrol, A7) at 288g/km (£790).

Of the 55,130 Mercedes-Benz SLKs licensed in the UK at 31 December 2025 (DfT), 81% were first used between 2002 and 2016 and so pay by CO2 band, 5% from 2018 onwards and pay the flat rate, and 6% before 2001, taxed by engine size; the remaining 8% were first used in 2001 or 2017, when the rules changed part-way through the year.

Mercedes-Benz SLK tax by year it was sold

Versions in the VCA database each year, taxed as if first registered then. Use the year on the V5C to narrow the range, then the CO2 figure to find the exact band.

VCA snapshots from July 2001 to August 2016; the August 2011 snapshot is published only as a spreadsheet and is not used, so 2011 counts only versions listed both before and after it.

Mercedes-Benz SLK registered from April 2017

The Mercedes-Benz SLK was last listed in the VCA database in September 2021, so it is no longer sold new. A used one first registered from 1 April 2017 pays the £200 standard rate, plus the Expensive Car Supplement if it applies.

Whether a particular Mercedes-Benz SLK pays the £440 Expensive Car Supplement depends on its original list price including options; 73 Auto's list-price reference does not confirm enough Mercedes-Benz SLK prices to say how many versions do. A registration check shows it for a specific car.

Limitations

Rates are the 2026/27 rates for a 12-month licence taken out from 2026-04-01; paying monthly or for six months costs slightly more. The CO2 figure is the official type-approval figure the VCA published when each version was on sale, which is normally the figure on the V5C, but a car's own V5C is what DVLA uses. Some versions were sold under a different model name (for example estate or MPV variants), and the VCA's list does not say how many of each were sold, so the version counts are not a guide to how common each band is on the road. The Expensive Car Supplement depends on the original list price including options, which the VCA list does not carry. Figures are calculated with 73 Auto's VED engine from the DVLA rate tables.
