Marion County property tax bills officially went digital this year. Starting with the spring 2026 invoice, the Marion County Treasurer's office offers full paperless billing — your TS-1 tax statement delivered electronically instead of in the mailbox. The rollout was announced by Treasurer Barbara A. Lawrence's office in September 2025 and covered by WISH-TV, and the spring cycle that just closed on May 11 was the first one where Indianapolis owners could skip paper entirely.
If you own property in Marion County, paperless billing is worth setting up before the fall installment — but it comes with real legal pitfalls that the enrollment page doesn't dwell on. Here is how the system works, who should use it, and where it can bite you.
What actually changed
Until this year, every Marion County parcel generated a mailed TS-1 statement twice a year — spring and fall — printed and posted by the treasurer's office in the City-County Building. With paperless billing enrolled:
- Your tax bill is delivered electronically through InvoiceCloud, the county's payment vendor
- You get an email notification when each installment bill is ready
- You view, download, and pay the bill from the same portal
- The paper statement stops coming
The due dates themselves did not change. For 2026, installments are due May 11, 2026 (the spring deadline moved off the usual May 10 because of the calendar) and November 10, 2026. Paperless enrollment has zero effect on when money is owed — only on how the bill reaches you.

How to enroll, step by step
Enrollment runs through the county's InvoiceCloud portal:
- Go to invoicecloud.com/indy
- Click Register Now (if you already have an InvoiceCloud account from paying online in prior years, just sign in at the top right instead)
- Add your parcel information — you'll want your 18-digit Marion County parcel number, which appears on any prior TS-1 statement or in the AribaTax property lookup
- Click Search Invoices to link the parcel's billing history to your account
- Opt in to paperless delivery in your account settings
Once enrolled, repeat step 3 and 4 for each additional parcel you own. Every parcel must be linked individually — enrolling one rental does not enroll your portfolio.
Note
The 60-parcel ceiling. Owners of more than 60 parcels are not eligible for paperless billing under the treasurer's program rules. Large landlords and institutional owners will keep receiving paper statements and should continue managing bills through their existing bulk processes.
If anything goes sideways during registration, the treasurer's tax information line is 317-327-4444, and the office publishes program details at treasurer.indy.gov. The office itself is in the City-County Building at 200 East Washington Street, Suite 1060.
The legal pitfall: an ignored e-bill is still a bill
Here is the part that matters more than the convenience pitch. Indiana law is blunt about non-delivery: under IC 6-1.1-22-8.1, failure to receive a tax statement does not relieve you of the obligation to pay on time, and it does not waive penalties. That rule predates paperless billing — owners have lost late-penalty disputes for decades after mail went astray — and it applies with equal force to an email that lands in your spam folder.
The penalty math makes this concrete. Indiana imposes a 5% penalty on a late installment if you have no prior delinquencies and pay within 30 days, and 10% otherwise. On a $4,000 installment, that's $200 to $400 lost to a filtered email.
So if you go paperless:
- Whitelist the sender. Add the InvoiceCloud notification address to your contacts the day you enroll.
- Don't rely on the notification at all. Calendar both due dates — May 11 and November 10 for 2026 — and treat the email as a reminder, not the trigger.
- Log in once per cycle even if no email arrives. The bill exists in the portal whether or not the notification reached you.
- Keep your email current. If you change email providers, updating your InvoiceCloud profile is now as important as filing a change of address with the post office used to be.
Warning
Spring 2026 already happened. If you enrolled in paperless billing early, missed the email, and blew past May 11, the penalty has already attached. Pay the delinquent installment now to stop it at the lower tier, and call 317-327-4444 about your situation — but do not expect "I didn't see the email" to succeed as a penalty waiver argument. The statute forecloses it.
If your mortgage company pays your taxes
A large share of Indianapolis homeowners never write a tax check — the escrow line in the monthly mortgage payment covers it, and the servicer pays the county directly. Two notes for this group:
You can still enroll, and probably should. Paperless enrollment gets you the actual TS-1 statement, which shows your assessed value, your deductions, the certified tax rate applied to your parcel, and your circuit breaker cap credit. Escrowed homeowners who never see their statement routinely miss a dropped homestead deduction or an assessment spike until the escrow analysis arrives a year later. Reviewing the e-bill each cycle is the cheapest audit you can run on your servicer — and on the assessor.
Enrollment does not redirect the payment obligation. The servicer pulls tax data through its own channels; your paperless setting doesn't interfere. But if you refinance or your loan is sold mid-year, escrow handoffs are exactly when payments fall through cracks. An owner who can see the bill and confirm "paid" status in the portal catches that in days instead of months.
For landlords and multi-parcel owners
If you hold between two and 60 Marion County parcels, paperless billing is a genuine workflow upgrade — with caveats:
- Link every parcel and verify the count. After enrollment, confirm the portal shows an invoice for each parcel you own. A parcel you forgot to link still generates a paper bill to whatever mailing address the auditor has on file, which may be a property you sold, a prior office, or a tenant's mailbox.
- Use one account, not one per LLC email. Consolidating parcels under a single login gives you one dashboard for the whole portfolio at each installment.
- Export and archive each statement. Download the PDF every cycle. Tax statements back up your Schedule E deductions, and pulling historical statements later is slower than saving them now.
- Watch newly acquired parcels. A parcel you bought in March may not have your information attached for the spring bill. Search for the new parcel in the portal immediately after closing rather than waiting for a notification that will go to the prior owner.
Over 60 parcels? You're excluded from the program — plan on paper statements and bulk payment files, and confirm your mailing address for every entity with the treasurer before the fall run.
What this doesn't change
Paperless billing is a delivery mechanism, nothing more. It does not affect:
- Your assessed value. That comes from the assessor via the Form 11 notice — Marion County's 2026 notices mailed April 28, and the deadline to appeal them on Form 130 is June 15, 2026, five days from today. The tax bill is downstream of that fight.
- Your deductions and credits. Homestead, over-65, and the new $300 homestead credit from SEA 1 all flow through the auditor regardless of billing format. The e-bill is simply where you verify they showed up.
- Payment methods. You can enroll in paperless delivery and still pay by mailed check, in person, or via escrow.
Bottom line
Enroll — the spring cycle proved the system works, and seeing your own TS-1 each cycle is the best habit in property tax hygiene. Set it up at invoicecloud.com/indy this month, link every parcel, whitelist the sender, and put November 10 on your calendar with your own reminder. The county's email is a courtesy. The deadline is the law.
