CT600L

When to use it

Didn't find your answer?

I've a client who is making an R&D claim to reduce tax (IW not claim the 14.5%). 
 

This is the first one I've done since 01 April 21 and Taxcalc has indicated that I need to include a CT600L. When I look at the boxes in that, I'm confused ... it seems that for R&D tax reducer claims, I don't complete it, only for RDEC claims and R&D cash back claims. 
 

So ... do I need to or not?

Thanks :)

No- CT600L not needed when R&D claim just reduces the net CT liability & doesnt generate a CT repayment by Tax Cr from loss surrender or RDEC claim.
