No one calls that a tax write off. That’s just normal operating expense, of course you can deduct depreciation expenses from taxes but as a business you don’t make decisions based on depreciation expenses and buying computers to save money on taxes. You’re buying assets to help you produce more and grow your profits at the end of the day which is the primary goal of the business. So I would argue those computers will make your employees more productive which will raise profits and taxes at the end of the day, which is perfectly normal.
