我老随便算了一下，聚聚税改给40万收入的双职工一年省了8w6

[DIYer]

你这智商真牛b，你现在用的就是他娘的聚聚时代的税制啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊，这个税改2025年就过期了，你要多交8万6啊

别搞笑了，我有不是聚聚当选后才开始交税的，我不相信40万年收入2016年的时候要交17万税。

[Jack12345]

拜登一遍遍大撒币给乌克兰是不是政府开支大？？

给乌克兰 没多少钱，你算一算就知道了。美国 没有派一个士兵。

如果不支持 乌克兰，让普丁得逞，以后美国要花 上百倍的钱，还要死伤无数

以前 杜鲁门总统 不支持老蒋，那点小钱 都不愿意花。结果后面 被迫打了 朝鲜战争和越南战争。死伤无数 花钱无数。现在乌克兰同样道理

以前打伊拉克 打阿富汗 才出的钱多，5万亿美元 都花出去了

[YouHi]

他除了丢人现眼还会啥？智商是遗传的，不能怪他。

属实。

[YouHi]

老领导借AI装傻，一群廊五分分钟上去舔。真是笑死个人了。

[Sunland]

chatgpt算的你也不过目一下就敢往上贴？
我都已经帮你摘出这两行了还问我没看懂？

当然是chatgpt啊，你没看懂啊，这个写错了而已，也就是说他有162，500 subject to 35%的税率，没啥问题啊

[/quote]

[Sunland]

他多算了七万，40万交17万的税， 42.5%。
小时候老师没强调要验算。

别搞笑了，我有不是聚聚当选后才开始交税的，我不相信40万年收入2016年的时候要交17万税。

[snowinwind]

这是啥数学水平？
2017年33%的税率区间是$233,351 - $416,700，你这里的taxable income才$379,200，怎么可能还有35%的税率？

TCJA is neutral for high income W2 families living in high state/local tax states, due to 10k SALT limit and AMT removal.

People who benefited significantly from TCJA - Schedule E income with large QBI (even SSTB are benefiting now with PTET).

[dustdevil]

这个算错了，总税收不是加起来，那些数字已经是累加过了的，这个拿任何一年1040gi读一下就清楚了。

40万收入，税改后大约省1万多一点的税，没有8万多那么多。

To compare the taxes under the 2017 tax system and the Tax Cuts and Jobs Act (TCJA) of 2018 for a married couple with a pre-tax income of $400,000 (40w), we will focus on the key differences in tax brackets, standard deductions, and exemptions between the two systems.

Key Changes in 2018 (TCJA):
Tax Brackets:

2017: 7 tax brackets, with the highest rate of 39.6% for incomes above $470,700 (married filing jointly).
2018 (TCJA): 7 tax brackets, with the highest rate of 37% for incomes above $600,000 (married filing jointly).
Standard Deduction:

2017: $12,700 for married filing jointly.
2018 (TCJA): $24,000 for married filing jointly (doubled).
Personal Exemptions:

2017: $4,050 per person (so $8,100 for a married couple).
2018 (TCJA): Personal exemptions were eliminated.
State and Local Tax (SALT) Deduction:

2017: Allowed unlimited deductions for state and local taxes.
2018 (TCJA): Capped SALT deductions at $10,000.
Child Tax Credit:

2017: $1,000 per child (phased out for higher incomes).
2018 (TCJA): Increased to $2,000 per child (higher phase-out limits).
Let's calculate and compare the approximate tax liability for a married couple with a $400,000 income under both tax systems.

1. 2017 Tax Liability:
Income: $400,000
Standard Deduction: $12,700
Personal Exemptions: $8,100 (for two people)
Taxable Income: $400,000 - $12,700 - $8,100 = $379,200
Using 2017 tax brackets:

Up to $18,650 taxed at 10% = $1,865
$18,650 to $75,900 taxed at 15% = $8,580
$75,900 to $153,100 taxed at 25% = $19,800
$153,100 to $233,350 taxed at 28% = $22,485
$233,350 to $416,700 taxed at 33% = $60,462
Remaining amount taxed at 35% ($379,200 - $416,700 = $162,500): $56,875
Total 2017 Tax Liability: $1,865 + $8,580 + $19,800 + $22,485 + $60,462 + $56,875 = $170,067

2. 2018 (TCJA) Tax Liability:
Income: $400,000
Standard Deduction: $24,000
Taxable Income: $400,000 - $24,000 = $376,000
Using 2018 tax brackets:

Up to $19,050 taxed at 10% = $1,905
$19,050 to $77,400 taxed at 12% = $7,008
$77,400 to $165,000 taxed at 22% = $19,266
$165,000 to $315,000 taxed at 24% = $36,000
Remaining amount taxed at 32% ($376,000 - $315,000 = $61,000): $19,520
Total 2018 (TCJA) Tax Liability: $1,905 + $7,008 + $19,266 + $36,000 + $19,520 = $83,699

Summary of Tax Liability:
2017 Tax Liability: $170,067
2018 (TCJA) Tax Liability: $83,699
Difference: The couple would save approximately $86,368 in taxes under the TCJA (2018) compared to 2017.
This comparison highlights that the TCJA generally reduced tax liability for higher-income earners by lowering tax rates and increasing standard deductions, though it eliminated personal exemptions and capped certain deductions like SALT.

我已经另外开主题了，married省了应该是1w6，gpt给我算错了。

这个算错了，总税收不是加起来，那些数字已经是累加过了的，这个拿任何一年1040gi读一下就清楚了。

40万收入，税改后大约省1万多一点的税，没有8万多那么多。

我已经另外开主题了，married省了应该是1w6，gpt给我算错了。

你又算错了 明明是16w

[snowinwind]

被人抓住就是GPT的错？你自己没脑子？40万收入17万的税，没有阶梯都超过40%了，但凡小学毕业都不会犯这个错吧！
你这还真是代表了川粉的智商水平。

那谁的税要多交？哪个收入层？

减少政府开支，大家的税都可以少交了。

以前打伊拉克 打阿富汗 才出的钱多，5万亿美元 都花出去了

就是这个算法，不用出兵，只要出点儿小钱就把欧洲和俄国这两个主要对手拖住，没有更划算的做法了。

看样子这一年到处哀嚎舔牎以为能省8万，结果发现屁也没省，有这点时间不如在后母堤坡门口多接几单。

trump税改总体是降个人所得税，但对于东西海岸的50w+收入的中产是加税。
现在chatgpt就可以很准确的计算这个，基本没错误，猛的一批。

···
For a married couple filing jointly with a W-2 income of \$1,000,000, a \$3,000,000 mortgage at 5% interest, living in California, and ignoring capital gains or losses:

- **Federal Tax Liability Increased by Approximately \$19,273** due to the TCJA.
- **State Tax Liability Remains Unchanged** at **\$96,009**.
- **Total Tax Liability Increased by Approximately \$19,273**.

This increase is primarily due to the **capping of the SALT deduction** and the **reduction of the mortgage interest deduction limit**, which significantly increased their taxable income under the new tax law.
···




calculate how much tax impact has trump tax cut and jobs act had for a couple with W2 income 1 million, with a mortgage of 3 mil, at 5% interest rate, living in california. Ignore capital gains or losses. Factor in effects from AMT in your calculation.





Sure, I'd be happy to help you calculate the **tax impact of the Trump Tax Cuts and Jobs Act (TCJA)** for a couple with a **W-2 income of \$1 million**, a **\$3 million mortgage at 5% interest**, living in **California**, while **ignoring capital gains or losses** and **factoring in the effects of the Alternative Minimum Tax (AMT)**.

---

## **Overview**

To determine the tax impact, we'll calculate the couple's **federal and state tax liabilities** both **before and after the TCJA**, including the effects of the AMT. The difference between the two scenarios will represent the tax impact of the TCJA on this couple.

---

## **Assumptions**

1. **Filing Status**: Married Filing Jointly.
2. **Income**: W-2 income of \$1,000,000.
3. **Mortgage**: \$3,000,000 at 5% interest (annual interest payments of \$150,000).
4. **State**: California residents.
5. **Deductions**: Itemized deductions include state and local taxes (SALT) and mortgage interest.
6. **AMT**: Effects are included in both pre-TCJA and post-TCJA calculations.
7. **Other Income/Deductions**: Ignoring capital gains, losses, and other potential deductions or credits for simplicity.

---

## **1. Pre-TCJA Tax Calculation (2017 Tax Year)**

### **A. Federal Income Tax**

#### **1. Calculate Itemized Deductions**

**a. State and Local Taxes (SALT):**

- **State Income Tax**: Calculated based on California's tax brackets.
- **Property Tax**: Estimated at **1%** of the property value (assumed \$3 million home), so **\$30,000**.

**i. California State Income Tax Calculation:**

California's tax brackets for Married Filing Jointly in 2017:

**Bracket**	**Taxable Income Range**	**Tax Rate**
1%	Up to \$16,030	1%
2%	\$16,031 – \$38,002	2%
4%	\$38,003 – \$59,978	4%
6%	\$59,979 – \$83,258	6%
8%	\$83,259 – \$105,224	8%
9.3%	\$105,225 – \$537,500	9.3%
10.3%	\$537,501 – \$645,502	10.3%
11.3%	\$645,503 – \$1,000,000	11.3%
12.3%	Over \$1,000,000	12.3%
**Additional Tax**	**Over \$1,000,000**	**1% Mental Health Services Tax**

**Calculating State Income Tax:**

- **Total State Income Tax**: Approximately **\$96,009** (detailed calculations provided in the appendix below).

**b. Total SALT Deduction:**

- **State Income Tax**: \$96,009
- **Property Tax**: \$30,000
- **Total SALT**: **\$126,009**

**c. Mortgage Interest Deduction:**

- **Interest Paid**: \$150,000
- **Deductible Limit**: Interest on up to **\$1,000,000** of mortgage debt.
- **Deductible Interest**: \$1,000,000 * 5% = **\$50,000**

**d. Total Itemized Deductions:**

- **Total Itemized Deductions**: **\$126,009 (SALT) + \$50,000 (Mortgage Interest) = \$176,009**

#### **2. Calculate Taxable Income**

- **Adjusted Gross Income (AGI)**: \$1,000,000 (since only W-2 income is considered)
- **Personal Exemptions**: Phased out at this income level.
- **Taxable Income**: **AGI - Itemized Deductions**

\[
\text{Taxable Income} = \$1,000,000 - \$176,009 = **\$823,991**
\]

#### **3. Calculate Federal Tax Liability**

Using **2017 federal tax brackets** for Married Filing Jointly:

**Bracket**	**Taxable Income Range**	**Tax Rate**
10%	Up to \$18,650	10%
15%	\$18,651 – \$75,900	15%
25%	\$75,901 – \$153,100	25%
28%	\$153,101 – \$233,350	28%
33%	\$233,351 – \$416,700	33%
35%	\$416,701 – \$470,700	35%
39.6%	Over \$470,700	39.6%

**Calculating Tax Liability:**

1. **10% Bracket**:

\[
\$18,650 \times 10\% = \$1,865
\]

2. **15% Bracket**:

\[
(\$75,900 - \$18,650) \times 15\% = \$57,250 \times 15\% = \$8,587.50
\]

3. **25% Bracket**:

\[
(\$153,100 - \$75,900) \times 25\% = \$77,200 \times 25\% = \$19,300
\]

4. **28% Bracket**:

\[
(\$233,350 - \$153,100) \times 28\% = \$80,250 \times 28\% = \$22,470
\]

5. **33% Bracket**:

\[
(\$416,700 - \$233,350) \times 33\% = \$183,350 \times 33\% = \$60,505.50
\]

6. **35% Bracket**:

\[
(\$470,700 - \$416,700) \times 35\% = \$54,000 \times 35\% = \$18,900
\]

7. **39.6% Bracket**:

\[
(\$823,991 - \$470,700) \times 39.6\% = \$353,291 \times 39.6\% = \$140,902.84
\]

**Total Federal Tax Liability (Before AMT):**

\[
\begin{align*}
\text{Total Tax} &= \$1,865 + \$8,587.50 + \$19,300 + \$22,470 + \$60,505.50 + \$18,900 + \$140,902.84 \\
&= **\$272,530.84**
\end{align*}
\]

#### **4. Calculate Alternative Minimum Tax (AMT)**

**a. AMTI Calculation:**

- **AMT Adjustments**: Add back SALT deductions.

\[
\text{Alternative Minimum Taxable Income (AMTI)} = \text{Taxable Income} + \text{SALT Deduction}
\]

\[
\text{AMTI} = \$823,991 + \$126,009 = **\$950,000**
\]

**b. AMT Exemption:**

- **2017 AMT Exemption for MFJ**: \$84,500
- **Exemption Phase-Out**: Begins at \$160,900 and is completely phased out by \$498,900 for MFJ.
- **At \$950,000**, the exemption is **fully phased out**.

**c. Tentative Minimum Tax (TMT):**

- **AMT Rates**:

- 26% on the first \$187,800 of AMTI.
- 28% on AMTI exceeding \$187,800.

**Calculating TMT:**

1. **26% Rate**:

\[
\$187,800 \times 26\% = \$48,828
\]

2. **28% Rate**:

\[
(\$950,000 - \$187,800) \times 28\% = \$762,200 \times 28\% = \$213,416
\]

3. **Total TMT**:

\[
\$48,828 + \$213,416 = **\$262,244**
\]

**d. AMT Liability:**

- **AMT Liability**: TMT - Regular Tax Liability (before AMT)
- Since **Regular Tax (\$272,530.84) > TMT (\$262,244)**, **AMT does not apply**.

**e. Final Federal Tax Liability (Pre-TCJA):**

- **Federal Tax**: **\$272,530.84**

### **B. California State Income Tax**

**Total State Income Tax**: **\$96,009** (calculation detailed in the appendix).

---

## **2. Post-TCJA Tax Calculation (2018 Tax Year and Beyond)**

### **A. Federal Income Tax**

#### **1. Calculate Itemized Deductions**

**a. State and Local Taxes (SALT):**

- **SALT Deduction Cap**: **\$10,000**

**b. Mortgage Interest Deduction:**

- **Deductible Limit**: Interest on up to **\$750,000** of mortgage debt.
- **Deductible Interest**: \$750,000 * 5% = **\$37,500**

**c. Total Itemized Deductions:**

- **Total Itemized Deductions**: **\$10,000 (SALT Cap) + \$37,500 (Mortgage Interest) = \$47,500**

**d. Standard Deduction vs. Itemized Deductions:**

- **Standard Deduction (MFJ)**: \$24,000
- **Decision**: **Itemize deductions** (\$47,500 > \$24,000)

#### **2. Calculate Taxable Income**

- **Taxable Income**: **AGI - Itemized Deductions**

\[
\text{Taxable Income} = \$1,000,000 - \$47,500 = **\$952,500**
\]

#### **3. Calculate Federal Tax Liability**

Using **2018 federal tax brackets** for Married Filing Jointly:

**Bracket**	**Taxable Income Range**	**Tax Rate**
10%	Up to \$19,050	10%
12%	\$19,051 – \$77,400	12%
22%	\$77,401 – \$165,000	22%
24%	\$165,001 – \$315,000	24%
32%	\$315,001 – \$400,000	32%
35%	\$400,001 – \$600,000	35%
37%	Over \$600,000	37%

**Calculating Tax Liability:**

1. **10% Bracket**:

\[
\$19,050 \times 10\% = \$1,905
\]

2. **12% Bracket**:

\[
(\$77,400 - \$19,050) \times 12\% = \$58,350 \times 12\% = \$7,002
\]

3. **22% Bracket**:

\[
(\$165,000 - \$77,400) \times 22\% = \$87,600 \times 22\% = \$19,272
\]

4. **24% Bracket**:

\[
(\$315,000 - \$165,000) \times 24\% = \$150,000 \times 24\% = \$36,000
\]

5. **32% Bracket**:

\[
(\$400,000 - \$315,000) \times 32\% = \$85,000 \times 32\% = \$27,200
\]

6. **35% Bracket**:

\[
(\$600,000 - \$400,000) \times 35\% = \$200,000 \times 35\% = \$70,000
\]

7. **37% Bracket**:

\[
(\$952,500 - \$600,000) \times 37\% = \$352,500 \times 37\% = \$130,425
\]

**Total Federal Tax Liability (Before AMT):**

\[
\begin{align*}
\text{Total Tax} &= \$1,905 + \$7,002 + \$19,272 + \$36,000 + \$27,200 + \$70,000 + \$130,425 \\
&= **\$291,804**
\end{align*}
\]

#### **4. Calculate Alternative Minimum Tax (AMT)**

**a. AMTI Calculation:**

- **AMT Adjustments**: Add back SALT deduction (now only \$10,000).

\[
\text{AMTI} = \$952,500 + \$10,000 = **\$962,500**
\]

**b. AMT Exemption:**

- **2018 AMT Exemption for MFJ**: \$109,400
- **Exemption Phase-Out**: Begins at **\$1,000,000**, fully phased out at \$1,437,600.
- **At AMTI of \$962,500**, the couple gets the **full exemption**.

**c. Tentative Minimum Tax (TMT):**

- **AMT Rates**:

- 26% on the first \$191,500 of AMTI.
- 28% on AMTI exceeding \$191,500.

**Calculating TMT:**

1. **26% Rate**:

\[
\$191,500 \times 26\% = \$49,790
\]

2. **28% Rate**:

\[
(\$962,500 - \$191,500) \times 28\% = \$771,000 \times 28\% = \$215,880
\]

3. **Total TMT**:

\[
\$49,790 + \$215,880 = **\$265,670**
\]

**d. AMT Liability:**

- **AMT Liability**: TMT - Regular Tax Liability (before AMT)
- Since **Regular Tax (\$291,804) > TMT (\$265,670)**, **AMT does not apply**.

**e. Final Federal Tax Liability (Post-TCJA):**

- **Federal Tax**: **\$291,804**

### **B. California State Income Tax**

**Total State Income Tax**: **\$96,009** (unchanged, as California did not conform to TCJA changes).

---

## **3. Comparing Pre-TCJA and Post-TCJA Tax Liabilities**

### **A. Federal Tax Liability**

- **Pre-TCJA Federal Tax**: \$272,530.84
- **Post-TCJA Federal Tax**: \$291,804

**Increase in Federal Tax Liability**:

\[
\$291,804 - \$272,530.84 = **\$19,273.16**
\]

### **B. California State Tax Liability**

- **Pre-TCJA State Tax**: \$96,009
- **Post-TCJA State Tax**: \$96,009

**No Change in State Tax Liability**

### **C. Total Tax Liability**

**Tax Component**	**Pre-TCJA**	**Post-TCJA**	**Difference**
**Federal Tax**	\$272,530.84	\$291,804	**+\$19,273.16**
**California State Tax**	\$96,009	\$96,009	\$0
**Total Tax Liability**	**\$368,539.84**	**\$387,813**	**+\$19,273.16**

---

## **4. **Tax Impact Summary**

The **Trump Tax Cuts and Jobs Act (TCJA)** resulted in an **increase of approximately \$19,273** in federal tax liability for the couple in this scenario. The **state tax liability remains unchanged**.

### **Key Factors Contributing to the Increased Federal Tax Liability:**

1. **SALT Deduction Cap**:

- **Pre-TCJA**: Full deduction of SALT (\$126,009).
- **Post-TCJA**: SALT deduction capped at **\$10,000**, effectively increasing taxable income by **\$116,009**.

2. **Mortgage Interest Deduction Limit**:

- **Pre-TCJA**: Interest on up to **\$1,000,000** of mortgage debt was deductible (\$50,000).
- **Post-TCJA**: Limit reduced to **\$750,000** of mortgage debt (\$37,500), decreasing the deduction by **\$12,500**.

3. **Tax Rate Changes**:

- While some tax brackets have lower rates post-TCJA, the loss of deductions led to a higher taxable income, pushing more income into higher tax brackets.

4. **AMT Adjustments**:

- **AMT exemption amounts increased**, and the phase-out thresholds were raised, but in both scenarios, AMT did not apply because the regular tax was higher.

---

## **Conclusion**

For a married couple filing jointly with a W-2 income of \$1,000,000, a \$3,000,000 mortgage at 5% interest, living in California, and ignoring capital gains or losses:

- **Federal Tax Liability Increased by Approximately \$19,273** due to the TCJA.
- **State Tax Liability Remains Unchanged** at **\$96,009**.
- **Total Tax Liability Increased by Approximately \$19,273**.

This increase is primarily due to the **capping of the SALT deduction** and the **reduction of the mortgage interest deduction limit**, which significantly increased their taxable income under the new tax law.

10.3%	\$537,501 – \$645,502	10.3%	(\$108,002) * 10.3% = **\$11,124.61**
11.3%	\$645,503 – \$1,000,000	11.3%	(\$354,497) * 11.3% = **\$40,058.84**
**Additional Tax**	**Over \$1,000,000**	**1%**	**Not Applicable**

3. **Total State Income Tax:**

\[
\begin{align*}
\text{Total Tax} &= \$160.30 + \$439.44 + \$879.04 + \$1,396.80 + \$1,757.28 + \$40,203.67 + \$11,124.61 + \$40,058.84 \\
&= **\$96,019.98**
\end{align*}
\]
