Section 179 and Bonus Depreciation for Small Businesses
A practical guide to Section 179, bonus depreciation, equipment write-offs, bookkeeping records, cash flow tradeoffs, and tax-advisor questions.
This guide is educational and is not tax advice. Section 179, bonus depreciation, listed property, vehicle limits, state rules, and entity-specific results should be confirmed with a qualified tax professional.
Short answer
Section 179 and bonus depreciation can allow faster deductions for qualifying business property, but the best choice depends on eligibility, taxable income, placed-in-service date, business use, cash flow, financing, state rules, and tax-advisor guidance.
Checklist
- Save invoices, purchase agreements, financing documents, and placed-in-service dates.
- Confirm business-use percentage and whether the property qualifies.
- Separate equipment purchases from repairs, supplies, loan payments, and ordinary expenses.
- Review Section 179, bonus depreciation, regular depreciation, and state treatment with a tax professional.
- Track depreciation schedules and asset disposals year to year.
Common mistakes
- Buying equipment only for the deduction without checking cash flow or debt payments.
- Recording financed equipment payments entirely as expenses.
- Forgetting business-use rules, vehicle limits, or placed-in-service timing.
- Assuming federal depreciation treatment is the same for every state.
Examples for service businesses
- A landscaping company buying mowers or trucks should track purchase price, financing, business use, and placed-in-service date.
- A contractor purchasing equipment should separate the asset from the loan and monthly payments in QuickBooks.
- A service business should compare tax savings with cash reserves, debt load, and maintenance costs.
Section 179 and bonus depreciation in plain English
Depreciation is how a business recovers the cost of certain property over time. Section 179 and bonus depreciation are tax rules that may allow faster deductions for qualifying property than regular depreciation.
IRS Publication 946 explains Section 179, special depreciation allowance, MACRS, listed property, qualification rules, limits, elections, and recapture concepts.
The deduction is not the same as cash savings
A deduction can reduce taxable income, but it does not make equipment free. The business still pays cash, takes on debt, or uses financing.
Before purchasing equipment, compare expected tax benefit with payment timing, interest, maintenance, insurance, storage, and revenue impact.
Records your tax preparer needs
Keep purchase invoices, loan agreements, payment schedules, trade-in details, business-use notes, placed-in-service dates, and disposal records.
In QuickBooks, the equipment purchase, loan liability, interest, principal payments, and depreciation entries should not be mixed together as one generic expense.
