§ 103350 Local Sales Tax Authority

The board can add a small sales or use tax of up to half a percent before Jan 1 2026, as long as the total taxes stay under the state‑set limit, and the money must be spent on transportation projects.

Key Takeaways

  • •The board can only set the tax at 0.5% or less.
  • •The tax must be approved before Jan 1 2026.
  • •All money collected must be used for transportation‑related projects in the county.
  • •If another state‑mandated transactions and use tax already exists, the board can’t add this one.

Example

A local shop sells a $1,200 laptop after the board approved a 0.5% tax before the 2026 deadline.

The shop adds a $6 tax (1,200 × 0.5%) to the price, and that $6 goes into a fund that will be used for things like bus routes or bike lanes in San Mateo County.

How to Calculate

Tax amount = Purchase price × Tax rate (maximum 0.5%)

  1. Find the purchase price of the item.
  2. Use the tax rate that the board set (it can’t be higher than 0.5%).
  3. Multiply the price by the rate (express the rate as a decimal, e.g., 0.5% = 0.005).
  4. The result is the amount of tax to add.

A family buys a $850 refrigerator after the board approved a 0.4% tax.

Result: $850 × 0.004 = $3.40 tax
