**What**
- Selects the correct tax line for an item given a calculation context.
**For later PR**
- Consider optimizations. Some thoughts:
- Even with global sales the number of rates in the DB is not likely to grow beyond ~1000.
- Can large orders with hundreds of items optimize somehow?
- Does it make sense to write a custom SQL query to do this?
- Support combined rate.
**Test cases covered**
The selection of tax rates take the following priority:
1. specific product rules - province
2. specific product type rules - province
3. default province rules
4. specific product rules - country
5. specific product type rules - country
6. default country rules
There are test cases for each of them under the following data seed structure:
### **US**
- **Default Rate**: 2%
- **Sub-Regions**
- CA
- Default Rate: 5%
- Overrides
- Reduced rate (for 3 product ids): 3%
- Reduced rate (for product type): 1%
- NY
- Default rate: 6%
- FL
- Default rate: 4%
- **Overrides**
- None
### **Denmark**
- **Default rate:** 25%
- **Sub-Regions**
- None
