car benefit calcs

nena · January 2009

Hi There can anyone help me understand this calcs of car

car benefit 2007/8

list price 18100 *18%(150g co2) =3258*158/365=1410 (had from 06.04. to 09.09)

list price 28111*19% (140g co2)=5341*208/365=3043(had from 10.09-to 05.04)

Total car benefit 4453

Car fuel 16900*18%*158/365=1316
" " 16900*19%*208/365=1829

Car fuel benefit= 3145

i think the calc should be:

car benefit

list price 18100 *18%(150g co2) =3258*158/365=1410 (had from 06.04. to 09.09)

list price 28111*18% (Actual 138g=135g co2) =5341*207/365=2869

car Fuel 16900*18%=3042

I would be very grateful for any reviews on this,

Cheers

This is what I have come up with

Both are diesel so add 3%
There are 366 days last year and also in your calcs (158+208)
£14400 for fuel benefit for 07/08

So

Car 1

List price £18100
CO2 150g

So 150-140 = 10/5 = 2 + 15 + 3 (diesel) = 20%

18100 x 20% = 3620 x 158/366 = 1563

Car 2

List price £28111
CO2 140g

So 140-140 = 0 + 15 + 3 (diesel) = 18%

28111 x 18% = 5060 x 208/366 = 2876

Total Co car benefit = £4439

Fuel

14400 x 20% x 158/366 = 1243
14400 x 18% x 208/366 = 1473

Total fuel benefit = £2716

Feel free to correct me if I am wrong

car benefit calcs

Thanks
nena

burg · January 2009

have edited above to reflect the cars being diesel

Roughly what you were missing -

Both are diesel so add 3%

There were 366 days last year your calcs are accounting for 366 ays (158+208) but you have apportioned out of 365

Fuel benefit calculation value for 07/08 was £14400 (£16900 is 08/09)

Let me know if you want more explanation

car Benefits

Thanks Ian

The first car was registered 01.01.05 that makes it 1V euro emissions
would that change the calcs, its just the revenue have calculated
the figures of 4453 car benefit and 3145 Fuel benefit

working on yours it means that they have taken 443 too much.

I will have another look at car tables on HMRC website, but if you come up with anything i would be most grateful.

its good that people like you are willing to help.

Thanks

The co car is not too far out only £14 so not too bad

The fuel is out by £429.

I recalculated on the 08/09 tax year amount of £16900 which comes to £3188 which is fairly close.

Is it definately for 07/08?

I would check to see what HMRC say the CO2's are on each car.

nena · January 2009

Sorry Ian

The car benefit is based on 2008/9 tax year

I cannot seem to find the car tables on revenue site- its a minefield!!

Thanks

If it is 08/09 then the

fuel benefit I calculate as follows

16900 x 20% = 3380 x 158/366 = £1459

16900 x 18% = 3042 x 208/366 = £1729

Total fuel benefit = £3188

Only a difference overall of £29 compared to HMRC figs so not too bad

Try here for figures

Hi Ian

Ive just managed to find P11d WS2 sheets

From them i have for 18100= 18% car registered 01.05.05 column 1 150 co2

28111-18% registered 10.09.08 column 2 135g ( actual co2=138 rounded to 135)

is this right?

Fuel would then be 16900* for both cars at18%

Both these cars are Euro 1V Diesel

Cheers

I still get this for car 1 as its got 150g emmissions

150-140 = 10

so 10/5 = 2

Starting = 15%
CO2 = 2%
Diesel = 3%

15 + 2 + 3 = 20%

nena · January 2009

Hi Ian

pardon my lack of knowledge,
I can see that 140g being the threshold -150=10
Taking this from 15% to 17% plus 3% diesel=20%

But on the P11D WS2 (2009) working sheets it does not give any of that just a straight % in section 5a

Cheers Nena

Found this

The rules governing the calculation of the appropriate percentage change in three ways with effect from 2008/09.

The lower threshold, the CO2 emissions figure which determines the appropriate percentage for all cars, is reduced from 140 to 135

Diesel (not Euro IV) supplement: 3%
Diesel (Euro IV) first reg on/before 31/12/05 cancel supplement, above

Car 1

150 - 135 = 15 /5 = 3 + 15 + 3 = 21% cancel diesel as euro IV -3 = 18%

Car 2

135 - 135 = 0 + 15 + 3 = 18%

Got there!

Sorry didn't realise the rules had changed, thats some cpd for this year!

nena · January 2009

car benefit calcs

Yeah I just wish they would list a little more info about the car. If voters are just to look at the cars and dont know about them, then they wouldnt know that his has an LT1 swap and another car might have something else. It is the car of the month, but we are kinda basing it on just the apperance of the car. Oh well, its a close race.
