Deductions
Tax deductions explained: what actually lowers your bill
6 min read
A deduction reduces the income you are taxed on. Here is how to choose between the standard deduction and itemizing, plus the business write-offs we add back for new clients every season.
Standard deduction or itemized deductions
Every filer gets a choice: take the flat standard deduction for your filing status, or itemize your actual deductible expenses. You take whichever is larger; you do not get both.
Most W-2 households come out ahead with the standard deduction. Itemizing usually wins when you pay mortgage interest, have large state and local taxes, gave significant charitable gifts, or had heavy out-of-pocket medical costs.
- Mortgage interest reported on Form 1098
- State and local income or sales taxes plus property taxes (capped)
- Charitable cash and non-cash donations with receipts
- Medical and dental costs above the income threshold
Deductions you can claim without itemizing
Some deductions come off your income before the standard-versus-itemized decision, so you keep them either way.
- Student loan interest reported on Form 1098-E
- Traditional IRA and HSA contributions you qualify for
- Educator classroom expenses
- Self-employed health insurance premiums
- One half of self-employment tax
Self-employed write-offs people miss
If you drive, freelance, sell online, or run a business, your expenses are the difference between a painful bill and a fair one. These are the ones we most often add for new clients.
- Business mileage, tolls, and parking with a mileage log
- The work-use share of your phone and internet
- Platform, app, and payment-processing fees
- Supplies, software, and equipment used for the business
- A qualifying home-office space used regularly and exclusively for work
- The qualified business income deduction on your net profit
Keep the records, not just the memory
A deduction is only as good as the proof behind it. Save receipts, bank and card statements, mileage logs, and year-end platform summaries. Upload them with your return and we will sort out what belongs where.
This guide is general tax information, not advice about your specific situation. Amounts and thresholds change each year — we confirm the current figures on your return.
