Fudged my tagging in Q1 and missed a few small VATable payments and receipts totalling about £29 of extra VAT owed.
I’ve now correctly tagged the transactions during Q2 and I see the extra money owed in the tax summary for the Q1 period. I’ve subsequently closed my VAT submission for Q2 - does the extra balance for Q1 get included into the numbers for the return in Q2?
