...I've selected the tiles which the tiler is purchasing.
Say they cost €1,000 plus VAT at 21% = €1,210 and labour is €500. Total = €1,710.
The tiler is charging VAT at 13.5% on the lot. Is this correct?
Do you mean he is charging you (€1,210 + €500) x 1.135 = €1,940.85?
In my view he should be charging (€1,000) X 1.05 = €1,050 for the tiles (Say 5% mark-up on the material costs)
So €1,050 + €500 = €1,550 + VAT = €1,550 X 1.21 = €1,875.50
Why, exactly?
"2/3 rds rule" only applies if material costs exceed 2/3s of total.
Otherwise, he can charge 13.5% for the lot.
When the materials portion of an invoice exceeds 2/3 rds of the invoice value net of VAT, than VAT is charged at the higher rate.What precisely is the two-thirds rule?
