How Deductions Work
- W-2 Employees
- 1099 Contractors
Federal Deductions
The Tax Cuts and Jobs Act (TCJA) of 2017 suspended the ability for W-2 employees to deduct unreimbursed business expenses on their federal return through 2025. W-2 employees are limited to the standard deduction on their federal return.TaxHomeBase still tracks your expenses because:- 5 states allow them — NY, CA, AL, HI, and AR didn’t conform to TCJA
- TCJA may expire — The suspension is scheduled to end after 2025
- Profitability tracking — Expenses are factored into per-assignment net profit
State-Level Deductions
If you work in a non-conforming state, TaxHomeBase automatically calculates your state deduction:| State | Floor | Rule |
|---|---|---|
| NY | 2% AGI | Deduct amount exceeding 2% of federal AGI |
| CA | None | Deductible from the first dollar |
| AL | 2% AGI | Same as NY |
| HI | 2% AGI | Same as NY |
| AR | 2% AGI | Same as NY |
