What you actually need to win

Most successful property tax appeals turn on three to five comparable assessments from the same neighborhood in the past 12 months, not on legal arguments. The comps are the product. The form is paperwork. trimmytaxes.com hands you both for free and lets you file it yourself.

Real comps, not estimates

We pull recent neighborhood sales the assessor will actually accept as evidence.

What we look for

Your assessment vs. what your neighbors are actually taxed on.

The county values homes in bulk. When it misreads your street, three comparable properties on the same block prove it. That gap is your case, and it is worth thousands.
