My understanding is that tax write-offs are deducted from the revenue, as in profit is revenue - expenses - write-offs, with different things being written of over different periods of time. So, let’s say vehicles are written off over 8 years, and I buy a truck for 40,000$, I can deduct 5,000$ each year from my revenue, meaning my taxable profits are 5,000$ less each year.
