Ohio Accelerated Sales Tax Payments: Deadlines and Penalties

Ohio accelerated sales tax payments apply to vendors whose sales tax remittances reach or exceed $75,000 in a calendar year. If that’s you, on or before the 23rd of each month you must electronically prepay at least 75% of that month’s anticipated sales tax, then file the full monthly return by the 23rd of the following month with the prepayment credited against the total. The rules for vendors sit in ORC 5739.122; parallel provisions cover direct payment permit holders (ORC 5739.032) and out-of-state sellers and in-state consumers (ORC 5741.121), and they work essentially the same way.¹

Who Has to Prepay, and When It Starts

The $75,000 trigger is the tax actually remitted in a calendar year, not gross sales or profit. Once you cross it, the tax commissioner adds you to the accelerated payment list and sends notice, but the obligation exists whether or not you receive that notice.²

The start date is the piece most vendors misread. The statute uses the phrase “second ensuing year,” so accelerated payments begin the year after next, not the very next year. Cross $75,000 in 2025, and you begin prepaying in 2027.² That two-year lag gives you time to set up mid-month remittance systems and cash flow, but it also means a single quiet year isn’t enough to pull you out.

Calculating the 75% Prepayment

By the 23rd of each month, you owe at least 75% of the sales tax you anticipate collecting for that same month.² Sales are still happening when the payment is due, so you’re estimating.

The statute builds in a safe harbor for that reason. Your payment cannot trigger an underpayment charge as long as it equals or exceeds 75% of the tax you reported for the same month in the immediately preceding calendar year.² That gives you two workable methods:

Estimate from real-time sales through the filing date. More accurate, but it depends on tight bookkeeping.
Use 75% of the same month’s reported liability from last year. Simpler, and it eliminates the underpayment charge risk even if this year’s sales come in higher.

Vendors with stable month-to-month revenue usually default to the prior-year method because it is predictable and safe.

Filing Deadlines Each Month

Two deadlines run on a staggered schedule:

The accelerated prepayment is due on or before the 23rd of the current month, covering sales still being made.²
The monthly return (UST-1) is due on or before the 23rd of the following month, reconciling total tax for the completed month against the prepayment already made.³

April’s prepayment is due April 23. April’s full return is due May 23. If the 23rd falls on a weekend or state holiday, the deadline moves to the next business day.

How the Prepayment Gets Credited

When you file the UST-1, the Department of Taxation credits your accelerated payment against the month’s total liability, and you remit only the remaining balance.² If the month came in slower than expected and your prepayment exceeded actual liability, the overage carries forward as a credit to the next return period.¹

The UST-1 has a dedicated line for the accelerated payment. You can send the prepayment and the return balance together in one transaction on the return date, or send them separately. If you send them separately, leave the accelerated payment line blank on the return itself.¹

How to Submit Payment

All accelerated payments must be electronic.² The Ohio Business Gateway at business.ohio.gov handles both the return and the payment in a single session.¹ You have two funds-transfer options:

ACH Debit. You authorize the state to pull the payment from your account through the Gateway. The state initiates the withdrawal.⁴
ACH Credit. Your bank pushes the payment to the state’s account. You have to register through the Treasurer of State first and coordinate the transfer with your financial institution.⁴

Credit card payment is available through the Gateway too, with a convenience fee attached. ACH Debit is the simplest for most vendors because the whole process stays inside the Gateway. ACH Credit tends to suit businesses that want tight control over outbound transfer timing or that route payments through treasury management systems.

Underpayment Charges

If your prepayment comes in below 75% of your actual liability for the month, the tax commissioner may impose an additional charge of up to 5% of the underpaid amount.² This is separate from any late-filing penalties on the return itself.

The Department of Taxation does not assess this charge on every shortfall. It typically applies when all three of these are true at once: the prepayment falls substantially below 75% of actual liability, it also misses the prior-year safe harbor amount, and the vendor has a pattern of understating anticipated liability.¹ Even then, the charge can be waived if the vendor shows the shortfall came from an unanticipated swing in sales.

The cleanest defense is the prior-year method. Pay 75% of what you reported for the same month last year, and the underpayment charge cannot apply no matter how the current month turns out.²

How to Exit Accelerated Status

Getting out of the program takes two consecutive calendar years with sales tax remittances under $75,000. After that, you’re relieved of accelerated payment obligations starting the following year.² Climb back to $75,000 or more in a later year, and the two-year clock restarts.

You can also apply directly to the tax commissioner to be excused from accelerated remittance for a specific period. The commissioner may grant it for “good cause shown,” a phrase the statute leaves undefined.² Seasonal businesses with sharply uneven cash flow and vendors under temporary financial strain are the usual candidates.

Personal Liability If You Fall Behind

Sales tax is a trust fund tax. Customers pay it to you, and you hold it briefly before remitting it to the state. When a corporation, LLC, or business trust fails to remit, Ohio does not confine its collection to the business. Under ORC 5739.33 and Ohio Administrative Rule 5703-9-49, officers, employees, and trustees can be held personally liable for unpaid sales tax.⁵

When more than one person is responsible, liability is joint and several: the state can pursue any one of them for the entire amount rather than splitting it.⁵ That is what makes accelerated payment obligations especially high-stakes. Letting a $75,000-plus annual liability slide can create personal exposure that outlasts the business. If you’re an officer or managing member with signing authority over tax remittances, the entity’s liability shield does not cover this debt.
