Find an Audit, Report or Correct Office
Use the Massachusetts Office of the State Auditor to find independent audits of state agencies and contractors, understand public findings, report possible waste or abuse, and review specialized reports involving MassHealth, public benefits and local government.
This guide explains which official tool to use, what information to prepare, how to read an audit fairly, when a public-records request is appropriate, and which requests belong with another office.
Quick answer: choose the correct action
Use Audit Reports to find published findings, the waste-and-abuse form to suggest an area for a future state audit, the Bureau of Special Investigations to report suspected public-benefit fraud, and the public-records form to request existing records held by the State Auditor’s office.

Report possible waste or abuse effectively
Use this route when a Massachusetts state-funded program, agency or contractor may be losing or misusing public property or money, failing to serve residents effectively, or not meeting its responsibilities.
Prepare the tip before opening the form
Once the facts are organized, read the official instructions and use the online form. The form is intended for state-government operations that auditors may need to examine more closely.
Report suspected public-benefit fraud
The Bureau of Special Investigations investigates allegations involving covered public-assistance programs administered through agencies such as the Department of Transitional Assistance, Department of Children and Families and MassHealth.
Information that can help investigators
Use the official Mass.gov public-benefit-fraud reporting form.
9 a.m.–5 p.m., Monday–Friday.
Outside those hours, use extension 500 to leave a message.
After gathering the person, program and conduct details, use the BSI reporting page. Do not submit routine benefit-eligibility questions or an urgent safety emergency through this form.
Request public records from the State Auditor
File an OSA public-records request only when the record already exists and is held by the Office of the State Auditor. Audit reports and many recurring reports are already published, so search those first.

10 Ohio Property Tax Calculators & Auditor Tools
Built specifically for Ohio's 35% assessment ratio, current DTE forms, and 2026 Homestead, Owner-Occupancy, CAUV, Conveyance Fee, and Board of Revision rules. Every number reflects verified Ohio Department of Taxation amounts.

Verify with the official Ohio source
These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:
Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
