In Finland people who work from home and bought anything needed to work, for example a desk, chair, display or headphones, they get a tax refund.
I do feel too that the employer should provide the equipment and working environment.
I know the standard deduction was raised significantly to cover such items, and only a couple other deductions allowed in the simplified tax filing.
But if you want to go the complex route these things can still be deducted. Just may not be worth hiring a CPA to file your returns to get a couple hundred back as only the CPA wins in such a case....
