Contracting was so
Does the employer expect a certain dress code? Gotta write off some new fits. Have to drive across town to pick up something for a job? Better get paid for the time to drive there and back, along with the gas it took. Always use your computer in a certain area in your home? Congratulations, you have a home office and can write off a percentage of your property taxes, mortgage interest, utilities, insurance, repairs and renovations as long as its connected to the office or necessary for the office to be functional (this can include bathrooms if clients use them!)
Felt like living as a 1%er. Literally anything can be a business expense, depending on when and where you do it.
