# Facts recovered from blackbox.db (MCP return timed out; ingest succeeded) - **blackbox row id:** 37156 - **ts:** 2026-09-12T19:16:36 - **domain:** finance - **state:** flagged - **model_used:** l1_l2_admit:8b8da6e3dc3a - **confidence:** None - **source:** None ## Query US tax expenditures that benefit the wealthy and corporations, with annual federal revenue loss estimates: mortgage interest deduction, step-up basis at death, estate tax repeal, bonus depreciation, carried interest, offshore deferral, repatriation holiday, Puerto Rico Act 22, EB-5 visa. Give revenue loss per year where known. ## Result (verbatim from brain) Below is a detailed, sourced analysis of the US tax expenditures you listed, focusing on **annual federal revenue loss estimates** where available and credible. I've prioritized **official, nonpartisan estimates** from the Joint Committee on Taxation (JCT) and the U.S. Department of Treasury's Office of Tax Analysis (OTA), which are the gold standard for tax expenditure scoring. Where estimates are unavailable, outdated, or misleading (e.g., for hypothetical policies like "estate tax repeal" or one-time events like the repatriation holiday), I clarify the situation and provide the best available context. **Critical Notes Upfront:** 1. **"Tax Expenditure" Definition:** These are revenue losses due to special exemptions, exclusions, deductions, credits, preferential rates, or deferrals in the tax code. JCT/Treasury publish annual estimates. 2. **"Benefits the Wealthy/Corporations"**: While all listed items *can* benefit high-income individuals or corporations, the *degree* and *distributional impact* vary significantly. I note key distributional insights where JCT/OTA or reputable analyses (e.g., CBO, Tax Policy Center) provide them. 3. **Estimates are Point-in-Time:** Revenue loss estimates change yearly due to economic conditions, tax law changes (especially the 2017 TCJA), and methodological updates. I use the **most recent official annual estimates** (typically for FY 2023 or 2024 where available) from JCT's *Estimates of Federal Tax Expenditures for Fiscal Years 2023-2027* (released July 2023) and Treasury's *Tax Expenditures* report (FY 2023). Where JCT/Treasury doesn't provide an estimate, I state that clearly and note why. 4. **Avoiding Misconceptions:** Several items on your list are **not current, ongoing tax expenditures** as described (e.g., "estate tax repeal" isn't law; "repatriation holiday" was temporary). I clarify these to prevent misinformation. --- ### Analysis of Each Item | Item Description | Is it a Current, Ongoing Tax Expenditure? | Annual Federal Revenue Loss Estimate (Most Recent Official) | Source & Key Context | Distributional Impact (Wealthy/Corporate Benefit?) | | :---------------------------------------- | :---------------------------------------- | :---------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Mortgage Interest Deduction (MID)** | **Yes** | **~$25.0 billion** (FY 2023) | [JCT, *Estimates of Federal Tax Expenditures for FY 2023-2027*, Table 1, Line 25](https://www.jct.gov/publications/2023/jcx-23-23/)
*Note: Estimates fluctuate; was ~$20.5B in FY 2022 due to TCJA SALT cap interaction.* | **Moderate benefit to wealthy, but primarily benefits middle/upper-middle class.** JCT/OTA data shows ~50% of benefits go to taxpayers with AGI > $100k, but the *largest dollar share* goes to those $100k-$200k due to phaseout of itemizing for very high earners under TCJA. Top 1% gets ~15%. | | **Step-Up Basis at Death** | **Yes** | **~$50.0 billion** (FY 2023) | [JCT, *Estimates of Federal Tax Expenditures for FY 2023-2027*, Table 1, Line 112](https://www.jct.gov/publications/2023/jcx-23-23/)
*Note: This is a major estimate; JCT lists it as "Exclusion of capital gains at death."* | **Strong benefit to the wealthy.** Tax Policy Center (TPC) analysis shows **over 80% of benefits accrue to the top 1% of earners**, and nearly 50% to the top 0.1%. Heirs avoid capital gains tax on appreciated assets (stocks, real estate, businesses) inherited at death. | | **Estate Tax Repeal** | **No (Hypothetical/Proposed)** | **Not Applicable (Current Law)** | **Current Law:** The federal estate tax exists (exemption ~$13.61M per individual in 2024). **Repeal is not law.**
**Hypothetical Estimate (if repealed *today*):** JCT scored the *2017 TCJA's estate tax changes* (which doubled the exemption) as reducing revenue by **~$40-50B/year** *relative to prior law*. A full repeal would cost more (~$60-80B/year based on pre-TCJA baselines). [See JCT JCX-68-17 for TCJA scoring]. | **Would be a significant benefit to the very wealthy.** TPC estimates ~80% of estate tax benefits go to the top 0.1%. Repeal would primarily benefit estates >$20M. *Crucially, this is NOT a current tax expenditure; it's a policy proposal.* | | **Bonus Depreciation** | **Yes (Phasing Down)** | **~$50.0 billion** (FY 2023) | [JCT, *Estimates of Federal Tax Expenditures for FY 2023-2027*, Table 1, Line 72](https://www.jct.gov/publications/2023/jcx-23-23/)
*Note: 100% bonus depreciation for qualified property placed in service after 9/27/17 and before 1/1/23. Phasing down: 80% in 2023, 60% in 2024, 40% in 2025, 20% in 2026, 0% after 2026 (unless extended).* | **Primarily benefits corporations and business owners (including wealthy individuals via pass-throughs).** JCT/OTA doesn't routinely publish detailed distributionals, but TPC and CBO analyses indicate benefits flow heavily to capital-intensive industries and high-income business owners. Significant corporate benefit. | | **Carried Interest** | **Yes** | **~$1.8 billion** (FY 2023) | [JCT, *Estimates of Federal Tax Expenditures for FY 2023-2027*, Table 1, Line 105](https://www.jct.gov/publications/2023/jcx-23-23/)
*Note: Listed as "Capital gains treatment of certain income of investment services partners (carried interest)."*
*Note: Estimates are small but politically salient; was ~$2.0B in FY 2022.* | **Benefits wealthy fund managers (private equity, hedge funds, real estate).** While the dollar amount is modest compared to other items, the *distributional impact is highly skewed*. TPC estimates **over 90% of benefits go to the top 0.1% of earners**. It allows compensation to be taxed at long-term capital gains rates (20% + NIIT) instead of ordinary income rates (up to 37% + NIIT). | | **Offshore Deferral** | **Yes (Modified by TCJA)** | **~$95.0 billion** (FY 2023) | [JCT, *Estimates of Federal Tax Expenditures for FY 2023-2027*, Table 1, Line 90](https://www.jct.gov/publications/2023/jcx-23-23/)
*Note: Listed as "Deferral of income from controlled foreign corporations (normal tax method)".*
*Critical Context: TCJA fundamentally changed this with GILTI. This estimate reflects the *remaining* deferral benefit under the new system (primarily for certain types of foreign income not fully subject to GILTI, or due to complexities). Pre-TCJA, this estimate was ~$100-130B/year.* | **Benefits multinational corporations.** The deferral allows corps to delay US tax on foreign profits until repatriation. Post-TCJA, GILTI aims to tax foreign income currently, but complexities, exceptions, and foreign tax credits mean significant deferral still occurs. Benefits flow to corporate shareholders (skewed wealthy) and executives. | | **Repatriation Holiday** | **No (One-Time, 2017-2018)** | **Not an Annual Loss; Was a *Gain* in 2018** | **This was NOT an ongoing tax expenditure.** It was a **one-time provision** in the 2017 TCJA (Section 965) imposing a **mandatory transition tax** on previously untaxed foreign earnings of CFCs, *whether or not repatriated*.
**JCT Scored it as a *Revenue *GAIN***:** ~$338.8 billion over 10 years (2018-2027), with ~$300B+ in the first year (FY 2018). [See JCT JCX-68-17].
*It brought deferred earnings into the tax base *now*, increasing short-term revenue (though long-term effects are debated).* | **Corporations paid a one-time tax** (at 15.5% on cash, 8% on illiquid assets) on ~$2.6T of offshore earnings. While controversial, it was a *revenue raiser*, not a loss. Benefits to corporations came from the *lower rate* vs. potential future ordinary rates, but it increased immediate federal revenue. | | **Puerto Rico Act 22 (Now Act 60)** | **Indirect/Complex** | **No Reliable Federal Revenue Loss Estimate Available** | **Act 22 (now part of Act 60)** offers **100% exemption on Puerto Rico-sourced capital gains, dividends, and interest** for new residents who meet requirements.
**Federal Impact:** This primarily affects *Puerto Rican territorial taxes*, **not direct federal income tax**.
*Potential Federal Loss:* If individuals move to PR *solely* to avoid federal tax on *US-sourced* income (which Act 60 does *not* exempt), it could constitute illegal tax evasion. If they move and have *only* PR-sourced passive income, they may owe little/no federal tax (as PR-sourced income is generally exempt from federal tax for bona fide residents under IRC 933). **JCT/Treasury do not estimate a specific federal revenue loss** for Act 60/22 because:
1) It relies on bona fide residency tests (hard to model).
2) The primary tax benefit is territorial (PR), not federal.
3) Any federal loss would be indirect and small-scale compared to major expenditures. Estimates from advocacy groups (e.g., ITEP) suggesting large losses ($1B+) are highly speculative and not official. | **Primarily benefits wealthy individuals relocating to PR** (often crypto investors, entrepreneurs) seeking to avoid federal tax on *future* capital gains/dividends/interest *earned while bona fide PR residents*. However, the *direct federal revenue loss* is uncertain and likely modest compared to items like step-up basis or MID. Major criticism focuses on whether recipients maintain bona fide residency and whether it erodes the PR tax base without sufficient economic substance. | | **EB-5 Visa Program** | **Not a Tax Expenditure** | **Negligible Direct Federal Revenue Loss** | **EB-5** is an immigration program granting green cards for investment ($800k-$1.05M typically) in US businesses creating jobs.
**It is NOT a tax expenditure.** It does not create a special tax exemption, deduction, credit, or deferral in the Internal Revenue Code.
**Revenue Impact:** Any federal revenue effect is indirect and minimal:
* Potential *gain* from increased economic activity/jobs (taxable income).
* Potential *loss* if investors use it to structure investments for tax avoidance (e.g., pairing with foreign tax credits), but this is not the program's primary function and is hard to isolate.
JCT/Treasury **do not list EB-5 as a tax expenditure** in their annual reports. Any estimated impact would be buried in broader economic effects, not scored as a tax expenditure loss. | **Benefits foreign investors seeking residency** and US developers seeking capital. While some wealthy foreigners use it, it's not primarily a *US* tax avoidance tool for *US* citizens/corporations. Concerns exist about fraud and job creation efficacy, but it's not scored as a federal tax expenditure loss. | --- ### Key Summary & Caveats 1. **Largest Confirmed Annual Losses (FY 2023):** * Step-Up Basis at Death: **~$50.0 Billion** * Bonus Depreciation: **~$50.0 Billion** (phasing down) * Offshore Deferral (Post-TCJA): **~$95.0 Billion** (Note: This reflects the *remaining* deferral benefit under GILTI; pre-TCJA was higher) * Mortgage Interest Deduction: **~$25.0 Billion** * Carried Interest: **~$1.8 Billion** (small dollar amount, highly skewed benefit) 2. **Items That Are NOT Current Tax Expenditures (as described):** * **Estate Tax Repeal:** Not law; current estate tax exists. *Hypot ## Provenance none
