加州的州销售税率是多少？What is the California state sales tax rate?
州税率为 7.25%（Tax Foundation「2026 Sales Tax Rates」（截至 2026 年 1 月 1 日））。县、市等地方税在此基础上另外加收，加州税务局 CDTFA 城市与县税率表（2026 年 10 月）中最高的地方税率为 4.5%（综合 11.75%），所以总税率因地址而异。填入更高的地方税率时工具会提醒你确认，但仍会计算（上限 20%）。The state rate is 7.25% (Tax Foundation, 2026 Sales Tax Rates (as of 1 January 2026)). Counties, cities and districts add local rates on top; the highest local rate in the CDTFA city and county rate table (October 2026) is 4.5% (11.75% combined), so the total depends on the address. A higher local rate still calculates (up to 20%) but shows a warning to double-check.
怎么从含税价反推税前价？How do I back out the price from a total?
税前价 = 含税价 ÷ (1 + 综合税率)。选择「含税价 → 税前价」即可。Price = total ÷ (1 + combined rate). Choose Total incl. tax → price.
金额怎么取整？How are amounts rounded?
金额、税额和含税总价都按分（0.01）四舍五入；州税和地方税两项相加正好等于销售税合计。The amount, tax and total are rounded to the cent (0.01), and the state and local parts add up exactly to the total tax.
7.25% 里包括哪些？What does 7.25% include?
加州 7.25% 的州税率中含 1.25% 由州统一征收、分配给地方的部分（Tax Foundation 把它计入州税率）。各地「区域税」（district tax）再另外加收。California's 7.25% includes a 1.25% portion collected statewide for local governments (Tax Foundation counts it in the state rate). Local district taxes are added on top.
