Form 8992 Schedule B is where many teams stall. Once you organize the CFC roster, pull the right I‑1 lines, and apply the stop rule without hesitating, you protect partner time and file clean.
Schedule B is the consolidated group’s official ledger of CFC level amounts for GILTI, prepared once for the group and filed with the consolidated return.
Key Takeaways
- You prepare one Schedule B for the entire consolidated group, then complete a consolidated Form 8992. Member level Forms 8992 are prepared for records, not filed.
- In Part I, list every CFC with the exact EIN or Form 5471 reference ID and every §958(a) 10% U.S. shareholder with EIN. Populate tested income or loss, QBAI, and interest items.
- Apply the stop rule fast. If Part I total in column (h), tested loss QBAI, equals or exceeds column (g), tested income CFC QBAI, you stop after Form 8992 Part I, line 3.
- If column (g) is greater than column (h), complete columns (i) through (n) and all of Part II, then build owner Forms 8992 and the consolidated Form 8992.
- Pull tested income or loss from Schedule I‑1 Line 6, QBAI from Line 8, tested interest expense from Line 9d, and tested interest income from Line 10c, converting to U.S. dollars as required.
What Schedule B is and when it applies
Schedule B functions like a master control sheet for a consolidated group. You use it when any member is a U.S. shareholder of a CFC within §958(a). Part I captures the CFC roster, owners, and the key amounts from each CFC’s Schedule I‑1. Part II converts those amounts into shareholder level allocations that carry to each owner’s Form 8992, then to the group’s consolidated Form 8992.
How the stop rule decides your path
Total Part I columns, then compare column (h) tested loss QBAI to column (g) tested income CFC QBAI.
- If column (h) equals or exceeds column (g), you stop. Enter the column (g) and (h) totals on Form 8992 Part I, lines 1 and 2, compute line 3, and you are done.
- If column (g) is greater, continue through columns (i) through (n) and complete Part II.
Who must appear on Schedule B
- Every CFC owned within §958(a) by any group member, identified with the exact EIN or the exact Form 5471 reference ID used on the I‑1.
- Each §958(a) 10% U.S. shareholder, with name and EIN, tied to the correct CFC line.
The critical link to Form 8992
Schedule B drives two outputs. First, each U.S. shareholder completes its own Form 8992 using the Schedule B Part II allocations. Second, you aggregate those owner forms line by line to prepare the consolidated Form 8992 that gets filed with Schedule B. If the stop rule hits, the consolidated Form 8992 stops after Part I, line 3.
Pulling the right data from Form 5471 Schedule I‑1
Key I‑1 lines you actually use
- Line 6, tested income or tested loss, drives Part I columns (e) and (f).
- Line 8, QBAI for tested income CFCs, feeds the QBAI components used for DTIR.
- Line 9d, tested interest expense, and Line 10c, tested interest income, feed the specified interest build. Convert functional currency amounts to U.S. dollars using the average rate.
Matching identifiers is non‑negotiable
Your Schedule B identifiers must mirror Form 5471. Use the same EIN or the same reference ID that appears on the I‑1. This one to one match is what keeps pro rata shares from double counting when a CFC appears on more than one line for different owners.
Roles and responsibilities at a glance
| Who | What appears | Why it matters |
| CFCs | Name, EIN or reference ID | Establishes scope of tested items |
| U.S. shareholders | Names and EINs | Drives correct pro rata allocations |
| QBAI amounts | Part I and Part II | Determine DTIR and the stop decision |
| Common parent | Consolidated filer | Files Schedule B and consolidated 8992 |
Complete one Schedule B for the group, then file it with the consolidated return. Provide a copy to each member.
Pro tip, lock your tie out early, then run the stop rule before you invest time in Part II. It saves review hours and reduces rework.
Ownership and pro rata shares that stand up in review
Compute once, reconcile everywhere
Identify each §958(a) 10% U.S. shareholder for every CFC line, then report that owner’s pro rata share of tested income or loss, QBAI, and tested interest items in the designated columns. Part I columns for owners must reconcile to the CFC level totals so the same CFC is not counted twice.
Aggregate without double counting
When you roll up tested income and tested loss for the group, total each CFC’s amounts once, even if that CFC appears on multiple lines. The instructions explicitly caution against reflecting the same CFC more than once in the Part I totals. That is how you keep Form 8992 Part I lines 1 and 2 clean and the stop rule accurate.
Specified interest, then DTIR, then GILTI
The interest pipeline you must trace
- Pull tested interest expense from I‑1 Line 9d and tested interest income from Line 10c.
- Record the CFC level amounts and each owner’s pro rata share in Part I.
- In Part II, sort and sum across the group to get consolidated tested interest expense and income, then compute consolidated specified interest expense, floored at zero, and allocate it back to owners.
Building DTIR the right way
For each owner, DTIR equals 10% of that owner’s share of consolidated QBAI, reduced by its share of consolidated specified interest expense. The math happens on Schedule B, then carries into each owner’s Form 8992 and finally to the consolidated Form 8992, unless you stopped after line 3.
Step by step, start to file
A quick path you can follow under pressure
- Complete Part I columns (a) through (h) for all CFCs and owners.
- Total Part I, then apply the stop rule using columns (g) and (h).
- If continuing, complete columns (i) through (n) and all of Part II.
- Build owner Forms 8992 from Part II.
- Aggregate to the consolidated Form 8992 and file it with Schedule B.
Map to the I‑1, then lock the tie out
Every tested figure on Schedule B must trace back to Schedule I‑1. Use Line 6 for tested income or loss, Line 8 for QBAI, Line 9d for tested interest expense, and Line 10c for tested interest income. Convert to U.S. dollars using the average annual rate and keep the exchange proofs.
Common pitfalls that drain partner time
Misclassifying group members
Missing an owner, misreading §958(a), or mismatching EINs will ripple through Part I and Part II. Confirm each owner meets the 10% test, belongs in the group, and is listed on the right CFC lines for the inclusion year. Reconcile the sum of the owners’ tested income or loss back to each CFC’s Line 6.
Incomplete intercompany eliminations
Intercompany items can inflate tested income, QBAI, or tested interest. Scrub transfers that duplicate depreciable basis and remove intercompany interest pairs before you populate the specified interest columns, or DTIR will be distorted. Anchor every adjustment to documented eliminations.
Wrong pro rata allocations
Use ownership for the inclusion year and carry four decimal precision in your workpapers to avoid rounding drift, then keep those percentages tied to the exact CFC identifiers on Schedule B. Do not compute DTIR or specified interest if the stop rule says stop.
High tax exclusion and the 18.9% threshold
What “high taxed” means for GILTI
The elective GILTI high tax exclusion can remove items from gross tested income if the effective foreign tax rate on a tested unit exceeds 90% of the section 11 rate. With a 21% corporate rate, the threshold is 18.9%. The final regulations apply the election at the tested unit level and set out consistency rules. Keep the effective rate workpapers with your Schedule B file.
How the election changes Schedule B
If you elect the exclusion for a CFC inclusion year and an item qualifies, you exclude that item from gross tested income on Form 5471 and reflect zero tested income for that item when you compile Schedule B. That changes Part I totals, which can flip the stop rule, and it changes DTIR downstream. Maintain consistent identifiers and retain your tested unit computations.
Keep an eye on policy changes that affect section 11 or section 250, since they shift the math behind high tax and the size of the section 250 deduction. Model year by year and document your assumptions.
Section 250 on Form 8993, where GILTI becomes deductible
Your Form 8992 result flows into Form 8993 to compute the section 250 deduction and any taxable GILTI after the income limitation. For tax years beginning on or after January 1, 2018 and before January 1, 2026, corporations generally deduct 50% of GILTI. After that, absent new law, the deduction percentage is scheduled to reduce to 37.5%. Confirm your year open date and track changes.
Practical tips for Form 8993 alignment
- Confirm Form 8992 GILTI ties exactly to the amount carried into Form 8993.
- Test the taxable income limitation and note any haircut.
- Keep a short memo in the file that shows the percentage used and the authority for the year.
Filing deadlines, extensions, and timing that prevents fire drills
- A calendar year C corporation files by the 15th day of the fourth month after year end. If the due date falls on a weekend or legal holiday, you file on the next business day.
- A timely Form 7004 generally grants an automatic 6 month extension. Special 7 month rules apply to certain June 30 year ends through specific transition periods, so check your facts.
- An extension gives you time to file, not time to pay. Interest and penalties apply to unpaid tax even if you extend.
If you stopped after line 3 because column (h) equaled or exceeded column (g), you still file Schedule B with the consolidated Form 8992 to preserve the outcome.
Recordkeeping that stands up to questions
Build a file your reviewers will love
- Complete Form 5471 packages for each CFC, including Schedule I‑1 with exchange rate proofs.
- A Schedule B tie out that cross references every Part I and Part II figure to I‑1 Lines 6, 8, 9d, and 10c.
- QBAI basis schedules using ADS, with average basis computations and support for dual use property.
- Part II interest workings showing consolidated expense, consolidated income, specified interest, and allocation back to owners.
Amending when numbers change
When to correct
Amend if an error changes Net CFC tested income, DTIR, specified interest, or any Schedule B totals that affect a shareholder’s GILTI. Fix upstream Form 5471 first, then rerun Schedule B and Form 8992, and update Form 8993 if needed. Observe the statute and include a short explanation.
How to course correct without more headaches
- Reconfirm identifiers, rebuild Part I totals, and retest the stop rule.
- Recompute Part II allocations, then each owner’s Form 8992, then the consolidated Form 8992.
- If a high tax election is involved, confirm timing and attach the tested unit workpapers that support the effective rate.
FAQs
How do foreign currency moves affect Schedule B?
They change tested income, QBAI, and interest components when you convert functional currency amounts to U.S. dollars and when exchange gains or losses flow through the tested unit. Use the average exchange rate for I‑1 Lines 6 through 10c and keep the conversion calculations.
Can I e‑file with a large Schedule B attachment?
Yes. You can file a computer generated Schedule B if it conforms to the IRS version and you expand it as needed. Provide a copy to each member and file Schedule B with the consolidated return.
How are partial year acquisitions or dispositions handled?
Prorate ownership for the inclusion year and ensure the right owners are listed on the right CFC lines for the portion of the year they owned stock. Keep acquisition and disposition dates in the tie out so Part I and Part II numbers reflect the correct owners.
How does Schedule B link to the section 250 deduction?
When Form 8992 is complete, its GILTI result flows to Form 8993 for the section 250 deduction. Through years beginning before January 1, 2026, corporations generally deduct 50% of GILTI, subject to the income limitation.
A practical checklist for every close
The 9 point “no rework” flow
- Identify all §958(a) 10% U.S. shareholders and all CFCs with exact EINs or reference IDs.
- Pull I‑1 Lines 6, 8, 9d, and 10c, convert to U.S. dollars, and log exchange proofs.
- Complete Part I columns (a) through (h), total, and test the stop rule.
- If continuing, complete columns (i) through (n) and all of Part II.
- Build owner Forms 8992 from Part II.
- Aggregate to the consolidated Form 8992 and file it with Schedule B.
- Prepare the section 250 computation on Form 8993 with the correct year percentage.
- Confirm due dates and file Form 7004 if you need time. Remember, extension to file is not extension to pay.
- Archive the tie out and note any high tax election decisions with tested unit proofs.
