You reach line 20 of Schedule D and it asks whether lines 18 and 19 are both zero. Yours aren't — you sold a rental property, or a gold ETF, or you have a K-1 from a real estate partnership. So instead of the twenty-five-line worksheet in the 1040 instructions, you're sent to the Schedule D Tax Worksheet: roughly forty-seven lines buried in the Schedule D instructions, with no explanation of why it's twice as long.
The extra length exists for exactly one reason: two additional tax brackets that the shorter worksheet has no way to handle. This guide covers when you're required to use it, what those brackets are, how the calculation actually works, and the mistakes that make people overpay.

Schedule D line 20 is the decision point:
- Lines 18 and 19 both zero or blank → use the Qualified Dividends and Capital Gain Tax Worksheet in the Form 1040 instructions
- Either line 18 or line 19 is more than zero → use the Schedule D Tax Worksheet
You never complete both. Our line-by-line Schedule D instructions cover how you arrive at this fork.
What puts a number on line 18 — the 28% rate gain:
- Collectibles gains — art, antiques, rare coins, stamps, wine, and precious metals. This includes physical gold and silver, and, importantly, ETFs that hold physical metal, which are treated as collectibles despite trading like ordinary funds. A great many investors hit line 18 without realizing it, purely from a gold ETF position.
- Section 1202 gain — the taxable portion of a qualified small business stock gain where a partial exclusion applied. See QSBS and the Section 1202 exclusion.
What puts a number on line 19 — unrecaptured Section 1250 gain:
Depreciation recapture on real property, taxed at up to 25%. If you sold a rental property, or hold an interest in a real estate partnership or REIT that reported unrecaptured 1250 gain on a K-1 or 1099-DIV, this line has a number. Note that certain 1099-DIVs report unrecaptured Section 1250 gain in a dedicated box — a REIT holder can land here without ever selling real estate directly.
The Four Capital Gains Rates
The reason this worksheet exists is that "long-term capital gains rates" isn't one schedule — it's four ceilings applied to different asset categories:
| Category | Maximum rate | Where it comes from |
|---|---|---|
| Regular long-term gain and qualified dividends | 0% / 15% / 20% | Schedule D lines 15 and 16 |
| Unrecaptured Section 1250 gain | 25% | Schedule D line 19 |
| Collectibles and Section 1202 gain | 28% | Schedule D line 18 |
| Short-term gain | Ordinary rates | Schedule D line 7 |
The 25% and 28% figures are ceilings, not flat rates. If your marginal ordinary rate is below them, you pay the lower rate. Someone in the 12% bracket with a collectibles gain pays 12% on it, not 28%. The worksheet enforces that ceiling in both directions, which is a meaningful chunk of its length.
How the Worksheet Works
The Schedule D Tax Worksheet does the same conceptual job as the shorter one — split income into ordinary and preferential pieces, tax each at its own rate, add them up — but with five categories instead of three. Line numbering shifts between tax years; the sequence doesn't.
Block 1 — Establish the buckets.
Start from taxable income. Identify qualified dividends and net capital gain, then further identify the portions that are 28% rate gain (line 18) and unrecaptured 1250 gain (line 19). Subtract all preferential income from taxable income to get your ordinary income figure.
You now have four buckets: ordinary income, regular long-term gain and qualified dividends, unrecaptured 1250 gain, and 28% rate gain.
Block 2 — Fill the 0% bracket.
Bring in the 0% capital gains threshold for your filing status, see how much of it your ordinary income has already consumed, and tax whatever room remains at zero percent.
Block 3 — Fill the 15% bracket.
Bring in the 15% ceiling, subtract what's already been counted, and multiply the qualifying amount by 15%.
Block 4 — Fill the 20% bracket.
Regular long-term gain above the 15% ceiling is multiplied by 20%.
Block 5 — The 25% calculation.
Unrecaptured Section 1250 gain is stacked and taxed at the lower of 25% or your ordinary marginal rate. The worksheet does this by computing tax on ordinary income plus the 1250 gain using the tax table, then comparing against a 25% flat computation, and using whichever is smaller.
Block 6 — The 28% calculation.
The same treatment for collectibles and Section 1202 gain, capped at 28%.
Block 7 — Total and sanity-check.
Sum the ordinary tax and each bracket piece, then compare against tax on all taxable income at ordinary rates. You pay the smaller. As with the shorter worksheet, this final comparison guarantees the preferential calculation can never cost you more than plain ordinary treatment.
The Stacking Order That Determines Your Bill
Here's the part worth internalizing, because it's where the money is.
The categories stack in a specific order, from the bottom of your income upward:
- Ordinary income fills the lowest brackets
- Regular long-term gain and qualified dividends stack on top
- Unrecaptured Section 1250 gain stacks above that
- 28% rate gain sits at the top
This ordering is favorable to you. Because regular long-term gain gets first claim on the 0% and 15% brackets, the higher-rate categories are pushed up — but they're each capped, so pushing them up costs less than it would if the order were reversed.
The practical consequence: your ordinary income drives everything. A year with unusually low wages lets more of your regular gain sit in the 0% bracket, which in turn changes how much of your 1250 and collectibles gain gets taxed below its ceiling. This is why real estate sales and large collectibles dispositions are worth timing deliberately.
Where the Numbers Come From
Line 18 — 28% Rate Gain Worksheet. A short worksheet in the Schedule D instructions. It collects collectibles gains and losses from Form 8949, Section 1202 gain, and any 28% rate amounts passed through on a K-1. Collectibles losses offset collectibles gains here.
Line 19 — Unrecaptured Section 1250 Gain Worksheet. A longer worksheet, also in the Schedule D instructions. Sources include Form 4797 for property you sold directly, K-1 line entries from partnerships and S corporations, and the dedicated 1099-DIV box for REIT distributions. Our guide to Form 4797 vs Schedule D covers which form a property sale belongs on in the first place.
Both worksheets have to be completed before you can run the Schedule D Tax Worksheet, which is why this part of a return has a reputation.
Common Mistakes
- Using the short worksheet anyway. The most expensive error, and it usually goes the wrong direction — the shorter worksheet has no 25% or 28% bracket, so it understates tax and invites a notice.
- Missing a collectibles gain from an ETF. A physical-metal ETF produces collectibles treatment. Nothing on the 1099-B says so; the fund's tax literature does.
- Treating 25% and 28% as flat rates. They're ceilings. Filers in lower brackets pay their ordinary rate.
- Missing unrecaptured 1250 gain on a 1099-DIV. REIT investors frequently overlook it because they never sold real property.
- Forgetting collectibles losses. They offset collectibles gains on the 28% Rate Gain Worksheet before anything reaches Schedule D line 18.
- Omitting the 3.8% net investment income tax. It's computed separately on Form 8960 and isn't part of this worksheet at all.
FAQ
What is the Schedule D Tax Worksheet?
A worksheet in the Schedule D instructions that computes your tax when you have unrecaptured Section 1250 gain or 28% rate gain, handling brackets the shorter Form 1040 worksheet can't.
When do I use the Schedule D Tax Worksheet instead of the capital gains worksheet?
When Schedule D line 18 or line 19 is more than zero. If both are zero, use the Qualified Dividends and Capital Gain Tax Worksheet instead.
What is unrecaptured Section 1250 gain?
The portion of gain on real property attributable to depreciation you previously claimed. It's taxed at up to 25% rather than the normal long-term rates.
Why is my gold ETF taxed at 28%?
Funds holding physical precious metals are treated as collectibles for tax purposes, and collectibles gains carry a 28% maximum rate. The 1099-B won't flag this — the fund's tax documentation will.
Is the 28% rate a flat rate?
No, it's a ceiling. If your ordinary marginal rate is lower, you pay the lower rate. The worksheet enforces this.
Do I file this worksheet with my return?
No. It's a computation aid; only the resulting tax goes on Form 1040. Keep your copy with your records.
Does tax software handle this automatically?
Yes, provided the underlying transactions are categorized correctly. The categorization is the part that goes wrong — software can't know your ETF holds bullion unless the input says so.
Bottom Line
The Schedule D Tax Worksheet is the long version because the tax code has four capital gains ceilings, not one. You're routed here whenever collectibles, qualified small business stock, or real estate depreciation recapture enters the picture.
Two things matter more than the arithmetic. Confirm which worksheet Schedule D line 20 actually sends you to, and confirm your transactions are categorized correctly before you start — a misclassified collectibles gain or an overlooked 1250 amount on a 1099-DIV will produce a wrong answer no matter how carefully you fill in the lines.
