Pennsylvania Inheritance Tax Deadline and 5% Discount

---

Pennsylvania inheritance tax is due within nine months of death, but a 5 percent discount applies if the tax is paid within three months. Missing these deadlines can increase the cost of the estate and expose the executor to penalties or interest. For Pittsburgh-area families administering an estate, understanding these two deadlines is the first step in protecting the estate’s value.

At Lebovitz & Lebovitz, P.A., we assist executors and families throughout Pittsburgh with Pennsylvania inheritance tax filings, deadline management, and estate administration. If a family member has recently died, early attention to the tax obligation protects the estate and preserves the discount.

Pennsylvania Inheritance Tax Deadlines

Pennsylvania inheritance tax returns and payment are due nine months from the date of the decedent’s death. This deadline applies to the filing of the REV-1500 return and to the payment of any tax owed. An extension for filing may be available, but an extension to file does not extend the deadline to pay. Tax not paid within nine months begins to accrue interest.

The earlier deadline that most estates should be targeting is three months from the date of death. Under Pennsylvania law, a 5 percent discount is applied to the inheritance tax if the estimated tax is paid in full within that three-month window. The discount is calculated on the amount paid, and it is available even before the final tax return is filed. Many estates pay an estimated amount within three months to capture the discount, then file and reconcile the final return by the nine-month deadline.

Both deadlines are strict. The three-month window does not extend for holidays, weekends, or estate complexity. Executors who are still gathering asset values at month two should consider paying a conservative estimate of the tax now and adjusting later, rather than waiting and losing the discount entirely.

Who Is Responsible for Paying

The executor of the estate is responsible for filing the Pennsylvania inheritance tax return and paying the tax from estate assets. In Pittsburgh and across Pennsylvania, if no will exists, the administrator appointed by the Register of Wills has the same obligation. Personal liability can attach to an executor who distributes estate assets to beneficiaries before the tax is paid and satisfied, leaving no funds to cover the obligation.

In some cases, the beneficiaries may be asked to contribute their share of the tax directly, particularly when assets pass outside the probate estate, such as through joint accounts or beneficiary designations.

How the 5% Discount Works

The discount is straightforward in concept. If the estimated tax is $20,000 and the estate pays that amount within three months of death, the actual tax owed is reduced by $1,000. The estate pays $19,000. The discount is not applied automatically. The estate must make the payment, and the payment must be received by the Pennsylvania Department of Revenue within the three-month window.

Many families miss the discount because they are still in the early stages of grieving, gathering account information, or waiting for asset appraisals. The three-month window feels distant in the first weeks after a death. Whether the family is in Fox Chapel or across the county, by the time the estate is organized and the executor has a working picture of the tax exposure, the window has often closed.

Cash flow is the other common barrier. Pennsylvania inheritance tax is calculated on the gross value of the taxable estate, not on liquid assets alone. An estate that holds real estate, retirement accounts, or business interests may have significant taxable value but limited cash available to pay the tax within three months. In those situations, the executor may need to borrow against estate assets, request a distribution from a liquid account, or make a partial payment on the amount that can be confirmed. The 5 percent discount applies to tax paid within three months. Whether a partial or estimated payment qualifies for the discount on the amount tendered depends on how the Department of Revenue treats the payment, and that treatment is not guaranteed. Executors facing a cash constraint should consult an attorney before assuming a partial payment will receive discounted treatment.

What Happens If the Deadline Is Missed

Inheritance tax not paid by the nine-month deadline accrues interest under Pennsylvania law. The interest rate is set annually by the Department of Revenue and compounds on the unpaid balance. Interest begins accruing from the date the tax was due, not from the date the return is filed.

Penalties may also apply for failure to file or for underpayment. The Department of Revenue has authority to assess penalties on top of interest, increasing the total cost to the estate. In cases where the estate has distributed assets before satisfying the tax, the Department can pursue the beneficiaries who received distributions.

Executor exposure is the risk that receives the least attention. An executor who misses the deadline, fails to file, or allows the tax obligation to go unpaid may face personal liability for the unpaid tax and associated interest. Courts take fiduciary obligations seriously, and beneficiaries who suffer a loss due to executor negligence around tax deadlines have legal remedies. An executor who is uncertain about the timeline, the filing obligations, or the cash available to pay should consult an attorney promptly rather than waiting.
