TL;DR, The #1 tax mistake Los Angeles it consultants make:
Most Los Angeles it consultant owners miss significant deductions every year because their books don't capture industry-specific expenses separately. The most common mistake: not tracking hardware purchases for depreciation and missing home office deductions when working from home. These are fully deductible under IRS Publication 334 when tracked correctly, but only when tracked correctly.

IT Consultant owners in Los Angeles deal with a more complex financial picture than most realize. Professional services are generally not subject to California sales tax. Hardware and software sales may be taxable. LA city business tax applies. The result is a category of deductible expenses that many owners never fully capture.
The most costly mistake isn't dramatic. It's a quiet categorization error that surfaces at tax time, when it's already too late.
The #1 Mistake
For Los Angeles it consultants, the most commonly missed deduction involves not tracking hardware purchases for depreciation and missing home office deductions when working from home. These costs are real business expenses, and they're fully deductible under IRS Publication 334, but only when they're tracked separately in your bookkeeping records.
When they get lumped into a generic expense category, they can't be substantiated at tax time. Your accountant works with what you give them. If it's not in the books correctly, it doesn't get deducted.
This is exactly what Bench fixes.

What Los Angeles IT Consultants Can Deduct
If your books are properly categorized, Los Angeles it consultants can deduct:
- computer and server equipment depreciation
- software subscriptions
- vehicle expenses for on-site work
- home office
- professional certifications
These aren't aggressive write-offs. They're standard deductions for your industry, deductible under IRS Publication 334, but they require proper documentation to claim. (Source: IRS Publication 334, irs.gov/pub/irs-pdf/p535.pdf)
The California Tax Layer
Professional services are generally not subject to California sales tax. Hardware and software sales may be taxable. LA city business tax applies. Getting this right requires bookkeeping that tracks California-specific categories separately, not combined into general expenses where they lose their deductibility.
When Most Los Angeles IT Consultants Figure This Out
Usually after a tax season that didn't go the way they expected. A bigger bill than anticipated. An accountant who needed more time to sort through incomplete records. The realization that something's been off for a while. It's what happens when a business grows past what informal bookkeeping can handle.
