Best Georgia Estate Tax Resource for Surviving Spouses Facing the Portability Deadline

For surviving spouses in Georgia who may eventually accumulate significant assets, the most important estate tax deadline after a spouse's death is not the final income tax return — it is the nine-month window to file Form 706 for the portability election. Missing this deadline means permanently forfeiting the deceased spouse's unused federal estate tax exemption. No Georgia agency, no national tax software, and no free resource adequately explains what this deadline means, who it affects, and what happens when it is missed.

The best resource for a surviving spouse navigating this situation is a Georgia estate tax guide that explains the portability decision in plain language, combined with a CPA or estate attorney who actually prepares and files the Form 706. The guide handles the education; the professional handles the filing.

What the Portability Election Is

Under the federal estate and gift tax rules as updated by the One Big Beautiful Bill Act in July 2025, each individual has a $15 million federal estate tax exemption ($30 million for married couples under portability). This exemption protects estate assets from the 40% federal estate tax.

The key word is "under portability" — because portability is not automatic.

When the first spouse dies, their unused federal exemption does not automatically transfer to the surviving spouse. The executor of the first spouse's estate must file a complete IRS Form 706 (United States Estate Tax Return) within nine months of the date of death to formally elect portability and transfer the deceased spouse's unused exemption to the survivor.

If no Form 706 is filed within that window, the deceased spouse's exemption expires. The surviving spouse is left with only their own individual $15 million exemption rather than the combined $30 million.

Why This Matters for Georgia Surviving Spouses

Georgia has no state estate tax. Surviving spouses do not owe Georgia taxes on the estate transfer itself. But the federal estate tax exposure is real for wealthier estates, and the portability election is the mechanism that doubles the surviving spouse's protection.

Consider a Georgia couple where the combined marital estate — a home, investment accounts, business interests, retirement accounts — is worth $12 million at the time of the first spouse's death. The estate is entirely non-taxable; no Form 706 is legally required to avoid immediate tax. The executor does nothing.

Fifteen years later, the surviving spouse has accumulated additional assets. Their estate is now worth $18 million. Their individual exemption is $15 million (plus annual inflation indexing starting in 2027). The $3 million above their exemption is taxed at 40% — a $1.2 million federal tax bill.

If the executor had filed Form 706 for the portability election when the first spouse died, the surviving spouse would have had a combined $30 million in exemption (or close to it, accounting for inflation adjustments). The estate would owe nothing.

This is the portability trap: the decision must be made before anyone knows whether it will matter, and the window is only nine months.

Who This Is For

A Georgia estate tax guide combined with professional Form 706 preparation is the right approach for surviving spouses who:

• Are under the $15 million individual threshold today but could accumulate more over time
• Own significant real estate, business interests, or investment assets that are likely to appreciate
• Want to preserve optionality — making the election costs money but preserves a significant tax benefit if it turns out to be needed
• Are unsure whether portability applies to their situation and need a plain-language explanation before engaging an attorney

The portability decision is also relevant for spouses where one held most of the marital wealth. If the wealthier spouse dies first and the surviving spouse inherits substantially, the surviving spouse's estate may be large enough to eventually benefit from the combined exemption.

Who This Is NOT For

Surviving spouses who do not need to focus on portability:

• Combined estates that are clearly and permanently under $15 million with no expected significant appreciation
• Situations where no assets are passing through the taxable estate (all assets in trusts, beneficiary-designated accounts, or other non-probate mechanisms that pass outside the estate)
• Non-citizen surviving spouses — different rules apply; consult an estate attorney immediately

The Nine-Month Window: What It Requires

To elect portability, the executor must file a complete Form 706 within nine months of the date of death. A six-month extension is available (Form 4768), giving a total of 15 months. There is also a late portability election procedure under Rev. Proc. 2022-32 that allows certain estates to make the election up to five years after death, but this requires the estate to have been under the filing threshold and comes with additional complexity.

Form 706 requires:

• A complete inventory of all assets in the gross estate, with date-of-death valuations
• All deductions claimed against the estate
• A computation of the Deceased Spousal Unused Exclusion (DSUE) amount being transferred to the surviving spouse
• The surviving spouse's Social Security number

Preparing Form 706 solely for portability — not because estate tax is owed — typically costs $2,000 to $5,000 in professional fees for an estate attorney or CPA specializing in federal estate tax. The economic case: $2,000 to $5,000 now versus a potentially multimillion-dollar tax savings decades later.

The Other Tax Issues Surviving Spouses Face in Georgia

Portability is the highest-stakes decision, but surviving spouses in Georgia are also navigating several other concurrent obligations and opportunities:

Year's Support: The Property Tax Waiver

Under O.C.G.A. § 53-3-1, a surviving spouse has the right to petition the Georgia probate court for a Year's Support award — an allocation of estate assets for their support and maintenance for the 12 months following the death. A successful award:

• Takes absolute priority over all unsecured creditors (credit cards, medical bills)
• Can override the terms of the will if the surviving spouse was inadequately provided for
• Waives real property taxes on the family home for one full year under O.C.G.A. § 53-3-4

The 24-month filing window is strict. Remarriage before the petition is filed permanently forfeits the right. For a surviving spouse facing a significant property tax bill while managing estate administration, this petition can generate thousands of dollars in immediate cash-flow savings.

A Georgia estate tax guide covers the Year's Support opportunity in practical terms that law firm blogs and national software do not.

The Final Joint Return and Refund Claims

The surviving spouse can file a joint return for the year of death — signing as the surviving spouse, not as a personal representative. If the couple was owed a Georgia state refund, that check may arrive in the deceased's name alone, triggering the GA-5347 refund claim process: notarized form, original unendorsed check, death certificate, and certified court appointment documentation.

The Homestead Exemption Transfer

Georgia's homestead exemption for the primary residence continues after a spouse's death — but must be updated with the county tax assessor's office. Unremarried surviving spouses of certain veterans and peace officers qualify for enhanced exemptions up to $121,812 under O.C.G.A. § 48-5-52.1.

What the Available Resources Cover (and Miss)

The gap: no single free resource covers all of these in the sequence a surviving spouse actually encounters them. The portability decision must be made in the first nine months. The Year's Support petition must be filed within 24 months. The refund claim arises immediately. The joint return is due April 15.

Tradeoffs Stated Honestly

The portability election costs real money to execute. Form 706 preparation is not a DIY filing even with a guide. It requires a professional. The $2,000 to $5,000 cost is justified only if the surviving spouse's estate might eventually benefit from the additional exemption.

Skipping portability is a permanent decision. There is no "revisit this later" option outside the formal extension and late election procedures. If you are uncertain whether portability matters for your situation, the cost of deciding wrong is asymmetric: the cost of making the election you didn't need is a few thousand dollars; the cost of skipping an election you did need can be millions.

A guide cannot tell you whether portability is worth electing for your specific estate. That requires a conversation with a CPA or estate attorney who knows your full financial picture. The guide explains the mechanics and the stakes; the professional advises on your specific situation.

Year's Support is often more immediately impactful for surviving spouses managing current cash flow. The property tax waiver, the creditor shield, and the will override can all generate more immediate financial benefit than a portability election that may or may not matter decades from now.

FAQ

Does every surviving spouse in Georgia need to file Form 706 for portability?

No. The portability election is only relevant if the surviving spouse's estate might eventually exceed their individual federal exemption. For couples with modest estates well under $15 million with no expectation of substantial appreciation, the portability election is probably not worth the cost to file. For couples with growing assets — real estate, business interests, significant investment portfolios — the election is worth careful consideration. A CPA or estate attorney familiar with the full financial picture should advise.

What happens if the nine-month window passes without filing?

The deceased spouse's unused exemption is permanently forfeited — unless the estate qualifies for the late portability election procedure under Rev. Proc. 2022-32, which requires the estate to have been below the estate tax filing threshold. This late election can be made up to five years after death but involves additional IRS scrutiny and procedural complexity. It is always preferable to file within the original nine-month window.

Can a surviving spouse file Form 706 themselves without a CPA?

Technically, there is no legal requirement to use a professional. Practically, preparing Form 706 requires a complete inventory of all estate assets with date-of-death valuations, an understanding of applicable deductions, and computation of the DSUE amount. This is a complex federal tax return that requires formal appraisals and estate planning knowledge. Most surviving spouses engaging a qualified estate attorney or CPA for Form 706 find the fee worthwhile relative to the potential savings.

Does the Year's Support petition affect the federal estate tax?

Year's Support is a Georgia state law mechanism operating within the probate court. Its effect on federal estate tax depends on how the award is structured. Assets passing to a surviving spouse generally qualify for the federal marital deduction, regardless of whether they pass through Year's Support or another mechanism. A CPA or estate attorney can advise on the interplay in complex estates.

What is the unremarried surviving spouse homestead exemption in Georgia?

Under O.C.G.A. § 48-5-52.1, unremarried surviving spouses of certain deceased veterans or peace officers may qualify for an enhanced homestead property tax exemption of up to $121,812. This exemption applies to the assessed value of the primary residence and must be applied for with the county tax assessor's office. The exact amount and eligibility criteria vary by the nature of the deceased spouse's service and cause of death.

Is a Georgia estate tax guide worth using if I am also hiring a CPA?

Yes — for different reasons. A guide explains the full landscape, including Georgia-specific provisions like Year's Support and the GA-5347 refund process that a CPA focused on federal tax returns may not address. Arriving at a CPA meeting with an informed understanding of the complete picture reduces billable time spent on orientation and helps you ask the right questions about the portability election, fiscal year election for the estate, and Form 501 thresholds.

The Georgia Final Tax and Estate Tax Guide covers the portability election decision, Year's Support mechanics, the GA-5347 refund claim, and every other tax obligation a surviving spouse faces after a death in Georgia — in plain language, in the order you encounter them.
