Celsari
Celsari helps municipalities, school districts and nonprofits with three federal matters that run on deadlines: accessible public documents, refunds for clean energy projects, and ARPA closeout. We do the legwork and put the right professional in front of every decision.
The clerk, manager or finance director who handles one of these usually handles the other two. Each is driven by a rule or a deadline, and each is mostly organizing, checking and paperwork, which is what we do.
Due April 26, 2027 or 2028
The ADA rule requires the PDFs on your website to be readable by people with disabilities. We rebuild your current agendas, minutes, forms and notices, set up templates so new ones come out right, and keep a record of the work.
Filing season runs through spring 2027
Tax-exempt and government owners of solar, battery storage and EV charging projects can claim the federal credit as a direct payment. We find the projects, organize the paperwork and bring in a licensed tax preparer.
Spend by December 31, 2026
ARPA dollars not spent by the deadline go back to Treasury. We map the balances at risk and prepare the documentation to move them to eligible projects within Treasury’s rules, then help with final reporting.
Federal rules reward careful paperwork, and they punish guesses. So we stay in our lane and say plainly where it ends.
We never ask for your passwords. Anything that goes to the IRS or to Treasury is reviewed and submitted by your own people or by the licensed professional who signs it.
| Matter | Celsari | Decided and signed by |
|---|---|---|
| Documents | Inventory, triage, repair, templates, report | Your staff post the files and decide what to archive |
| Clean energy refunds | Find projects, gather and organize documents, keep the calendar | A licensed tax preparer determines the credit, prepares, signs and files the return |
| ARPA | Reconcile balances, draft the plan and the written justification, prepare portal entries | Your finance director reviews and submits; your auditor or counsel reviews larger moves |
Celsari is a service of RevHarvester LLC, a Maine company based in Portland. It is run by Matt Garbarino, who builds software that turns public records and published rules into plain, checkable work. We began with documents, because we measured the problem: in a first scan of 284 local government websites in Vermont, Maine and New Hampshire, 87% of the PDFs we tested failed a basic accessibility check. The refund and ARPA services followed because the same offices carry all three deadlines.
We would rather tell you we cannot help than sell you something you do not need. If your ARPA funds are already spent, or your project does not qualify, we will say so.
Tell us about your municipality, school district or organization. We will tell you honestly whether we can help, and what to ask your own advisers if we cannot.
