Self employed and mileage

mrbilbo72

So need some help here when I submit my invoice later this weekend.

I'm self employed and pay tax under the construction industry scheme so flat rate of 20% at source then submit a tax return.

I've started getting work from a new company and they pay mileage at 20p a mile.

Do I add this amount to my total on the invoice to be taxed at source OR is it added after the tax deduction and then get paid my net amount + mileage. 

Any advice would be much appreciated been self employed for 15 years and never had this paid before.

Yes. See section 2.16:
