What happens to my tax bill if I move?
What the new home is taxed at from scratch, versus carrying your old Prop 13 base with you under Prop 19 — and the gap between the two over ten years.

| Tax with the base transferred | $3,410 |
| Difference each year | $5,940 |
| Difference over ten yearsBoth bills grow at the 2% Prop 13 cap | $65,041 |
Transferring your Prop 13 base saves about $495 a month, $65,041 over ten years. For many owners over 55 this is the difference between being able to move and staying put.
Ten years of tax bills

Prop 19 base transfers are for a principal residence, for owners 55 or older, severely disabled, or rebuilding after a wildfire or disaster; up to three times; the replacement must be bought within two years. Your county assessor decides. Not tax advice.
