Understanding every factor — USA rules
In Illinois (and most US states), vehicle sales tax depends on these core elements. Our calculator applies them exactly as the Illinois Department of Revenue does:
- Purchase price – the total sale amount before deductions. Always included.
- Trade‑in credit – Illinois subtracts trade‑in value from the price, lowering your tax.
- Rebates – manufacturer rebates are deducted before tax (federal standards agree).
- State rate (6.25%) – fixed for all vehicles in Illinois.
- Local rate (county/city) – varies from 0.25% to 1.25%. Use the table below as reference.
- Model year – does not change tax % but is used for registration class. We include it for your records.

Trade‑in and rebates consistently reduce the taxable base – that’s the rule in 48 US states, including Illinois.
📅 Model year & average retained value (for reference)
| Model year | Typical retained value % | Estimated taxable portion (if used) |
|---|---|---|
| 2026 | 95–100% | full price (new) |
| 2025 | 80–90% | dealer may use actual sale price |
| 2024 | 70–80% | still actual price, not NADA |
| 2023 | 60–72% | tax on selling price (not book) |
| 2022 | 50–65% | tax based on what you pay |
Illinois taxes the actual selling price, not the model year. This table helps you estimate depreciation but does not change tax rate.
📄 Other costs at dealership (USA)
| Fee type | Typical amount | Taxable? |
|---|---|---|
| Documentation fee | $150 – $350 | No (not part of sales tax) |
| Title & registration | $95 – $250 | No |
| License plates | $30 – $200 | No |
| Dealer preparation | often included | sometimes taxable, ask dealer |
These fees are not subject to Illinois sales tax but are due at purchase. The calculator focuses strictly on tax.
