Advice needed.. I currently use simplified accounting for self assessment return, and flat rate for van. I purchased a new van at month 11 (100% business use) How do I record this purchase in my self assessment? Do I calculate flat rate for 11 months of the year for my old van as I would normally do and record the full cost less part ex value in with the total expenses? and going forward into 23/24 do I continue to use flat rate ? Any advice greatly appreciated.
