One date decides whether you have anything to compute on Form 4808: was the gift made on or before December 31, 1976? Gifts after that date are already integrated under the unified estate and gift tax system, so there is no IRC Section 2012 credit to claim. The first time a junior preparer pencils the credit onto a Form 706, that is the question to ask before anything else.

This 30-line worksheet (Rev. November 2016, Catalog No. 42021H) supports a Form 706 and runs two limitations. The allowable credit on line 30 is the smaller of the first limitation on line 12 or the second limitation on line 29, so both have to be worked, with the donor's figures sourced from the original Form 709.

Key Takeaways

• Form 4808, Computation of Credit for Gift Tax, is the IRS worksheet used to compute the IRC §2012 credit for gift tax on gifts made on or before December 31, 1976 that are included in the decedent's gross estate. No credit is allowed for gifts made after that date.
• It is not a standalone return. Complete the four header fields – Estate of, Date of death, Name of donee, and Schedule number – and attach Form 4808 to the estate's Form 706 as a supporting schedule.
• The 30-line form runs two limitations. The allowable credit on line 30 is the smaller of the total first limitation on line 12 or the second limitation on line 29, so both must be computed.
• Source the donor's gift figures from the original Form 709 (taxable gifts, specific exemption, and total gift tax paid), and use Column B for the portion of a split gift the spouse reported. When gifts span more than one pre-1977 year, run a separate Form 4808 for each year.

What Form 4808 actually is

A worksheet, not a standalone return

Form 4808, Computation of Credit for Gift Tax, is an IRS worksheet that supports a Form 706 estate tax return and computes the IRC §2012 credit for gift tax on gifts made on or before December 31, 1976 that are included in the decedent's gross estate. It is published by the Department of the Treasury – Internal Revenue Service, and the current version is the November 2016 revision (Catalog No. 42021H).

The form is identified by its header fields – Estate of, Date of death, Name of donee, and a Schedule number that ties it to the estate tax return. That header is the tell that Form 4808 is filed as a schedule of the estate return, never as a separate filing.

The §2012 credit, in plain terms

The legal authority is IRC §2012, which provides a credit against the federal estate tax for gift tax the decedent paid on gifts made on or before December 31, 1976 that are also included in the gross estate. The credit exists to prevent the same transfer from being taxed twice, once under the pre-1977 gift tax and again as part of the taxable estate.

No credit is allowed for gifts made after December 31, 1976. The Tax Reform Act of 1976 replaced the old §2012 credit for later gifts with the unified estate and gift tax system, which accounts for post-1976 gifts through adjusted taxable gifts on Form 706 instead.

A quick note on process control

If you run an estate or tax practice that handles §2012 computations only once in a while, consistency saves you from rework and unhappy review loops. Standard operating procedures around source documents, naming, and version control will cut your review time in half. This is the kind of delivery discipline our team at Accountably builds for firms, and we apply the same checklists when an estate engagement reaches back to decades-old gift records.

Who needs Form 4808 and when

You reach for Form 4808 only in a narrow situation: the estate's gross estate includes a gift the decedent made on or before December 31, 1976, the decedent paid gift tax on that gift, and you are now preparing the Form 706 estate tax return. When all three are true, the §2012 credit is on the table and the worksheet computes how much of it the estate can claim.

If the gift was made after December 31, 1976, stop. There is no §2012 credit to compute, because that gift is already handled through adjusted taxable gifts on Form 706. Confirming the gift date before you open the worksheet is the single most useful screen on this form.

Documents you need before you start

• The decedent's original Form(s) 709, the source for taxable gifts (Schedule A, line (j)), specific exemption (Schedule A, line (h)(3)), and total gift tax paid (page 1, line 8).
• The estate's draft Form 706, which supplies adjusted taxable gifts (page 1, line 4) and the tentative-tax figure for line 28.
• Estate tax values for the gifted property, so the estate-value side of the worksheet (lines 13 to 20) reflects what is actually included in the gross estate.
• The header details for the worksheet: Estate of, Date of death, Name of donee, and the Schedule number that ties it to the estate return.
• Records of any gift-splitting election on the original Form 709, so the spouse-reported portion can be allocated to Column B.

Step‑by‑step, filling Form 4808 correctly

Prepare the file the right way

Download Form 4808 from IRS.gov, save it locally, then open it in a current PDF reader. Some in‑browser viewers flatten fields or drop calculations, which can cause printing issues on multi-column forms like this one. Saving and working locally keeps the two computation columns intact.

The gift side, lines 1 through 12

• Complete the header: Estate of, Date of death, Name of donee, and Schedule number.
• Enter the gift tax amount on line 1, total the annual exclusion, marital deduction, and charitable deduction on line 5, and subtract line 5 from line 1 to reach the net amount of gift on line 6.
• Pull taxable gifts (line 7), specific exemption (line 8), and total gift tax paid (line 10) from the decedent's original Form 709.
• Compute the first limitation on line 11 as (line 6 / line 9) x line 10, then total it across columns on line 12.

The estate side, lines 13 through 30

Lines 13 to 20 work out the estate tax value of the gift, reducing it for any attributable marital deduction (line 17) and charitable deduction (line 18). Line 21 brings in the gross estate, lines 22 to 27 build the estate tax base plus adjusted taxable gifts, and line 28 carries the tentative-tax figure from Form 706. Compute the second limitation on line 29 as (line 20 / line 27) x line 28.

Finish on line 30

Enter the smaller of the total first limitation (line 12) or the second limitation (line 29) on line 30. That figure is the allowable §2012 credit. Form 4808 is not signed or issued by anyone at a counter; it is attached to the estate's Form 706 as a supporting schedule.

How the two limitations work

The two limitations are the heart of Form 4808, and the credit is the smaller of them, so neither can be skipped. The first limitation (line 11, totaled on line 12) pro-rates the gift tax actually paid: it multiplies total gift tax paid (line 10) by the ratio of the net gift amount (line 6) to total taxable gifts plus specific exemption (line 9).

The second limitation (line 29) pro-rates the estate tax. It multiplies the tentative-tax figure (line 28) by the ratio of the value of the gift in the estate (line 20) to the estate tax base plus adjusted taxable gifts (line 27). Whichever limitation is smaller caps the credit, which is why line 30 reads "enter line 12 or 29, whichever is smaller."

Split gifts and Column B

Form 4808 provides two computation columns, A and B. Column B is used only for the portion of the donor's gift that the spouse reported in the case of split gifts. If the decedent's original Form 709 elected gift-splitting under IRC §2513, allocate the spouse-reported portion to Column B and the donor-reported portion to Column A.

Putting an entire split gift into Column A misrepresents how the gift was originally reported and distorts the first limitation total on line 12. When you see a gift-splitting election on the source Form 709, set up both columns before you start entering figures.

One worksheet per pre-1977 year

When gifts from more than one full taxable year are included in the gross estate, you cannot fold them into a single computation. The form requires a separate computation of both limitations for each taxable year, which in practice means a separate Form 4808 for each pre-1977 year of gifts represented in the estate.

Where Form 4808 fits on the estate return

Form 4808 is a computation worksheet, not a return you file on its own. Once both limitations are computed and the smaller figure is on line 30, the worksheet is attached to the estate's Form 706 as a supporting schedule and filed with the estate tax return. The Schedule number in the header is what ties it back to that return.

Keep your source documents in the same file: the original Forms 709 that fed lines 7, 8, and 10, and the Form 706 pages that fed lines 4 and 28. If a reviewer or the IRS questions the credit, a clean trail from the worksheet back to those source figures is what resolves it quickly.

Common mistakes you can avoid

The same handful of errors come up every time Form 4808 lands in a review, and each one traces back to treating the worksheet like a simple credit grab instead of a sourced computation. Here are the patterns I flag most often.

Quick reference, line-by-line sources

Form 4808 line	What it holds	Where the figure comes from
Line 7	Taxable gifts	Form 709, Schedule A, line (j)
Line 8	Specific exemption allowed	Form 709, Schedule A, line (h)(3)
Line 10	Total gift tax paid	Form 709, page 1, line 8
Line 26	Adjusted taxable gifts	Form 706, page 1, line 4
Line 28	Tentative tax less aggregate gift taxes payable and applicable credit	Form 706, page 1, line 12 (8-2013 revision)
Line 30	Limitation of credit	Smaller of line 12 or line 29

Tip, save your completed PDF with a clear name, for example, F4808_EstateName_YYYYMMDD.pdf, then archive the source Form 709 and Form 706 pages in the same folder. Future you, or your reviewer, will thank you.

Why the November 2016 revision still applies

Practitioners sometimes search for a newer Form 4808, assuming the November 2016 version is outdated. It is not. The IRS has not reissued the form because the §2012 credit applies only to gifts made on or before December 31, 1976, and that population of gifts cannot grow. Use the November 2016 revision (Catalog No. 42021H) for 2025 estate filings; no later revision exists and none is needed.

The one revision wrinkle to watch is on line 28. Form 4808 references Form 706 line 12 of the 8-2013 revision for "tentative tax less aggregate gift taxes payable and applicable credit amount." Later Form 706 revisions renumber their lines, so do not copy line 12 blindly from whatever Form 706 you are filing.

Map line 28 to the right Form 706 value

• Find the value labeled "tentative tax less aggregate gift taxes payable and applicable credit amount" on the Form 706 revision you are actually filing.
• Carry that value to Form 4808 line 28, even if it is no longer on line 12 of your Form 706.
• Tie adjusted taxable gifts on line 26 to Form 706 page 1, line 4, which is stable across revisions.
• Document the Form 706 revision used, so a reviewer can retrace the mapping.

Practical PDF tips that prevent bad output

• Save the form first, then open it in a current PDF reader before entering figures.
• Keep both computation columns visible so split gifts are not accidentally collapsed into Column A.
• Print from the reader rather than a browser button to preserve the field layout.
• Save a final, locked copy once you finish, so the working file is not overwritten by accident.

Reusable Checklists

These checklists are copy-paste ready for your estate-engagement SOPs, so the §2012 credit on Form 4808 gets computed and reviewed the same way every time.

Keep 4808 Season From Stalling

Form 4808 rarely drives its own deadline, but it lands on your desk in the middle of an estate engagement where the Form 706 filing date is already fixed. Because the worksheet reaches back to gifts made on or before December 31, 1976, the records you need are often decades old, and reconstructing the original Form 709 figures is where the work stalls. Missing a single pre-1977 gift, or copying the wrong figure from the source returns, can send the whole §2012 computation back for rework.

The fix is to treat Form 4808 as a sourcing exercise before it becomes a math exercise. Most of the delay comes from chasing the donor's original gift data, not from the limitation formulas themselves.

• Pull the decedent's original Forms 709 first, so taxable gifts (line 7) and total gift tax paid (line 10) trace to a source document before anyone touches line 11.
• Run a separate Form 4808, with both limitations, for each pre-1977 taxable year represented in the gross estate rather than aggregating years into one computation.
• Allocate split gifts correctly, with the donor-reported portion in Column A and the spouse-reported portion in Column B.
• Compute both limitations every time, the total first limitation on line 12 and the second limitation on line 29, then carry the smaller figure to line 30.
• Map the line 28 tentative-tax figure to the Form 706 revision you are actually filing, since the worksheet references the August 2013 revision.

When estate volume spikes, this is exactly the kind of structured, source-document-driven work our tax preparation and review teams handle inside your workflow, so the §2012 credit gets computed once and reviewed clean.

FAQs

What is Form 4808 used for?

Form 4808, Computation of Credit for Gift Tax, is an IRS worksheet that computes the IRC §2012 credit against the federal estate tax for gift tax the decedent paid on gifts made on or before December 31, 1976 that are included in the gross estate. No credit is allowed for gifts made after that date.

Is Form 4808 filed on its own?

No. Form 4808 is a computation worksheet, not a standalone return. It carries an Estate of, Date of death, Name of donee, and Schedule number header, and it is attached to the estate's Form 706 as a supporting schedule.

How is the allowable credit on Form 4808 determined?

The 30-line form runs two limitations. The allowable credit on line 30 is the smaller of the total first limitation on line 12 or the second limitation on line 29, so both must be computed before you can enter the credit.

Do gifts made after 1976 qualify for the Form 4808 credit?

No. The form's own title states no credit is allowed for gifts made after 12/31/76. Post-1976 gifts are integrated under the unified estate and gift tax system and are accounted for through adjusted taxable gifts on Form 706, not through Form 4808.

Which Form 4808 revision is current?

The November 2016 revision (Catalog No. 42021H) is still the current version. The IRS has not reissued it because the underlying §2012 credit applies only to pre-1977 gifts and the computation has not changed. Use the November 2016 revision for 2025 estate filings.
