PA Inheritance Tax 5 Percent Discount: How to Claim It Before the Window Closes

You are ninety days away from saving money that is yours to keep — and most executors in Pennsylvania never collect it.

The Commonwealth offers a five percent discount on inheritance tax payments made within three calendar months of the decedent's date of death. On a $400,000 estate passing to adult children, that discount is worth $900 at the 4.5% lineal rate — money that otherwise flows straight to the Pennsylvania Department of Revenue. On a larger estate with sibling or collateral heirs paying 12% or 15%, the savings scale accordingly.

The problem is the deadline. Three months is not long. When you factor in the time spent arranging a funeral, gathering paperwork, waiting for a death certificate, and finding a probate attorney, the ninety-day window can disappear before you have a complete picture of the estate's assets. This is where the estimated prepayment strategy comes in — and understanding it is the single most valuable procedural move an executor can make early in the administration process.

Why the Discount Exists

Pennsylvania's inheritance tax is due nine months after the date of death, along with Form REV-1500 (the Pennsylvania Inheritance Tax Return). The state created the five percent early-payment discount as a deliberate incentive to accelerate liquidity into state coffers. The Commonwealth would rather receive a slightly smaller tax check in month three than wait nine months for the full amount.

For you as the executor, this creates a rare alignment of interests. The discount reward is straightforward: pay early, pay less. The statute is unambiguous — any tax paid within three months of the date of death qualifies for the five percent reduction, regardless of whether the final REV-1500 has been filed yet.

The Core Problem: You May Not Know the Full Tax Yet

This is where inexperienced executors stall. They assume they need a complete and filed REV-1500 before they can send any money to the state. That assumption costs them the discount.

Pennsylvania allows — and actively encourages — estimated prepayments. You do not need to have completed the inheritance tax return to send a prepayment. You only need a reasonable estimate of the tax owed.

This is a legally recognized strategy. The executor calculates a good-faith approximation of the estate's taxable value and the resulting tax, remits that estimated amount to the Register of Wills within the three-month window, and then completes the formal filing at the nine-month mark. At that point, if the final tax calculation is higher than the prepayment, you pay the difference. If it is lower, you receive a refund. The five percent discount applies to the portion paid on time.

How to Calculate Your Estimate

You do not need a finalized appraisal or a complete inventory to run a workable estimate. You need a reasonable approximation of the gross taxable estate and the applicable rate.

Step 1: Identify the taxable assets.

Pennsylvania inheritance tax applies to all real and tangible personal property located in the Commonwealth, plus all intangible property (bank accounts, investment accounts, stocks, bonds) of a Pennsylvania resident decedent. Start with what you know: the approximate balance of bank accounts, the rough market value of any brokerage or retirement accounts, vehicles, and real estate.

Non-probate assets — joint accounts, TOD (Transfer-on-Death) accounts, and POD (Payable-on-Death) accounts — are also taxable in Pennsylvania. Do not exclude them from your estimate simply because they bypassed the Register of Wills.

Step 2: Apply the correct rate to each beneficiary.

Pennsylvania's inheritance tax rate depends on who is receiving the property, not on the total size of the estate:

• Surviving spouse and children age 21 or younger: 0% (exempt)
• Lineal descendants and ancestors (adult children, parents, grandchildren): 4.5%
• Siblings (full and half): 12%
• All other heirs (nieces, nephews, domestic partners, friends): 15%

In most estates, different beneficiaries receive different shares at different rates. Run the calculation separately for each class of beneficiary.

Step 3: Build in a conservative buffer.

Because this is an estimate, round up rather than down. If your real estate figure is uncertain, use the county tax assessment as a floor — not as a replacement for the required formal appraisal you will need for the REV-1500, but as a conservative minimum for the prepayment. Overpaying the estimate is harmless (you will receive a refund). Underpaying by a large margin means the unpaid balance does not qualify for the discount.

The Real Estate Appraisal Conflict

The single biggest obstacle to claiming the five percent discount is the real estate valuation problem. Pennsylvania requires that all assets on the REV-1500 be reported at fair market value as of the date of death. The Department of Revenue rejects county property tax assessments as a substitute for fair market value because assessed values routinely diverge from actual market conditions.

For the formal return, you will need a licensed appraiser. A competent residential appraisal typically takes two to four weeks from order to delivery — and you may be spending the first two weeks of the estate administration just obtaining death certificates, locating the will, and scheduling the probate appointment at the Register of Wills.

This is exactly why the estimated prepayment exists. Order the appraisal immediately after the death. Use the appraisal when it arrives to finalize your estimate, and send the prepayment before day ninety. You do not have to wait for the formal REV-1500 to capture the discount.

If the property has not been appraised by the three-month mark, use a conservative estimate based on comparable sales in the area or the listed tax assessment, and remit that amount. Adjustments can be made when you file the full return.

Where and How to Pay

The estimated prepayment does not go to the Pennsylvania Department of Revenue directly. It is submitted to the county Register of Wills in the county where the decedent was domiciled at the time of death. Each county has its own office, and some now accept payments electronically or by mail while others require in-person submission — check your county's specific procedures.

Include a clear written statement with the payment identifying it as an estimated prepayment on the estate of the decedent, referencing the date of death, the decedent's name, and the Social Security number. Keep a copy of the payment and any confirmation receipt as evidence that the payment was made within the discount window. This documentation is critical if the timing is ever challenged.

When you subsequently file the formal REV-1500 at the nine-month mark, you will credit the prepayment amount against the final liability.

What Happens If You Miss It

If the three-month window closes without a prepayment, the discount is permanently lost — there is no hardship exception and no late application. The remaining options are to pay the full tax by the nine-month deadline to avoid interest, or to file Form REV-1846 to request a six-month extension of the filing deadline.

One critical distinction: the extension extends the time to file the paperwork, not the time to pay the tax. The tax itself is due at nine months regardless. If you use the extension to delay filing but do not pay the underlying tax estimate, interest begins accruing immediately at the annually set penalty rate published by the Secretary of Revenue. The late filing penalty can reach 25% of the tax found due, or $1,000, whichever is less.

Missing both the discount window and the payment deadline is the kind of outcome that can trigger a surcharge petition against an executor by unhappy beneficiaries. They have every right to demand that you repay the estate for the discount you failed to capture.

The Lifetime Gifting Lookback

One often-overlooked factor in the estimate calculation: Pennsylvania claws back lifetime gifts made within one year of death. If the decedent made gifts to beneficiaries in the twelve months before they died, the value of those gifts (minus a $3,000 per-recipient annual exclusion) is added back into the taxable estate and taxed at the applicable beneficiary rate. If you are aware of any such gifts, include them in your estimate.

A Deadline That Rewards Speed

The five percent discount is Pennsylvania's way of incentivizing executors to move quickly and organize early. On estates with meaningful asset values, the savings are real and worthwhile. The strategy is straightforward — start gathering asset values within the first week, order a real estate appraisal immediately if real property is involved, and do not wait for a completed return before sending an estimated payment to the Register of Wills.
