1. RSUs (Restricted Stock Units): In-Depth Analysis

1.1. What Are RSUs and How Are They Taxed?

Restricted Stock Units (RSUs) are a form of equity compensation provided by employers, often vesting over a set period (e.g., 25% per year over 4 years). Your pay statement shows a Year-to-Date (YTD) RSU income of $321,171.72, indicating that a significant portion of your 2024 income comes from RSUs that vested during the year.

Taxation at Vesting

• Ordinary Income: When RSUs vest, their fair market value (FMV) on the vesting date is taxed as ordinary income. For you, $321,171.72 was added to your wages in 2024, reported on your W-2 (Box 1).
• Federal Tax Rate: Given your high income, you’re likely in the 37% federal tax bracket (for income over $609,350 single in 2024). The federal tax on $321,171.72 is approximately $118,833.54 (37%), though your employer withheld $27,699.40 YTD (per the pay statement), leaving a potential shortfall.
• Social Security and Medicare: RSUs are subject to payroll taxes:
  • Social Security: 6.2% up to the 2024 wage base limit ($168,600, likely adjusted from 2023’s $160,200). Your total wages (including RSUs) exceed this, so you’ve maxed out at $10,453.20 (6.2% of $168,600).
  • Medicare: 1.45% on all wages, plus 0.9% Additional Medicare Tax on wages over $200,000 (single). On $321,171.72, Medicare tax is $4,656.99 (1.45%), plus $1,029.60 (0.9% on the portion above $200,000), totaling $5,686.59.
• California State Tax: As a CA resident (or with CA-sourced income), RSUs are taxed at CA’s progressive rates (up to 12.3%, plus 1% Mental Health Services Tax if income exceeds $1 million). On $321,171.72, CA tax is approximately $39,504 (blended rate).

Taxation Upon Sale

If you sell RSU shares after vesting:

• Cost Basis: The FMV at vesting ($321,171.72) becomes your basis, since you were taxed on that amount.
• Capital Gain/Loss: If you sell for $350,000, your gain is $28,828.28. If sold within a year, it’s a short-term gain (taxed at 37%); if held over a year, it’s long-term (20% + 3.8% NIIT = 23.8%).
• Net Investment Income Tax (NIIT): The gain is subject to the 3.8% NIIT, adding $1,095.47.

1.2. Tax Strategies for RSUs

• Adjust Withholding: Your federal withholding ($27,699.40 YTD) is insufficient for the $118,833.54 tax on RSUs. Update your W-4 to increase withholding or make estimated tax payments (Form 1040-ES) to avoid penalties (IRC Section 6654).
• Maximize Pre-Tax Contributions: Contribute the maximum to your 401(k) ($23,500) and HSA ($4,150) to reduce AGI, saving $8,699 in federal tax (37%) and $3,108 in CA tax (12.3%).
• Timing Sales: Hold RSU shares for over a year to qualify for long-term capital gains rates (23.8% vs. 40.8% short-term).
• Charitable Donations: Donate RSU shares to charity (e.g., $10,000 worth). You avoid capital gains tax and deduct the FMV, saving $3,700 federally and $1,230 in CA tax.
• Offset with Losses: Use capital losses (discussed later) to offset RSU sale gains, reducing taxable income.

1.3. Compliance

• W-2 Reporting: Ensure your W-2 reflects $321,171.72 in Box 1.
• Schedule D/Form 8949: Report RSU sales, using Form 1099-B from your broker.
• Form 8960: Calculate NIIT on gains.

2. California State Tax Threshold: Detailed Breakdown

2.1. Filing Threshold for 2024

The California Franchise Tax Board (FTB) sets minimum income thresholds for filing a state tax return. For 2024 (filed in 2025), a single filer under 65 must file if:

• Gross Income: $22,177
• CA AGI: $17,742

Your total income ($471,171.72, including RSUs, Airbnb, and self-employment) far exceeds this threshold, requiring a CA return (Form 540 if a resident, Form 540NR if a nonresident with CA-sourced income).

2.2. CA Tax on Your Income

• CA AGI: After 401(k) ($23,500) and HSA ($4,150) contributions, your CA AGI is $443,521.72.
• Tax Rate: CA’s top rate is 12.3% (for income over $698,271 single). Your CA tax is approximately $44,352 (blended rate).
• Mental Health Services Tax: If your income exceeds $1 million, a 1% surcharge applies (not applicable here).

2.3. Strategies

• Reduce CA AGI: Maximize pre-tax contributions (401(k), HSA) to lower your CA tax liability.
• Multi-State Credits: Your pay statement shows WA deductions (e.g., WA Paid Family Leave). Claim a credit for WA taxes paid on your CA return (Form 540, Line 61).
• Itemized Deductions: Deduct mortgage interest from your Airbnb property on CA Schedule CA (Section B), potentially exceeding the $5,540 standard deduction.

2.4. Compliance

• Filing Deadline: April 15, 2025, or October 15, 2025, with an extension.
• NOL Suspension: CA suspends Net Operating Losses (NOLs) for 2024 if net business income exceeds $1 million (not applicable here).

3. Combined Social Security Tax Over-Withholding by Two Companies

3.1. Background

You worked for one company until May 3, 2024, were unemployed from May 3 to July 31, and started with a second company on July 31. Both companies withheld Social Security tax, potentially leading to over-withholding.

Social Security Tax Basics

• Rate: 6.2% on wages up to the 2024 wage base limit ($168,600).
• Maximum Tax: $10,453.20 (6.2% of $168,600).

Your Situation

• First Company (Jan 1 - May 3): Assume you earned $60,000. Social Security tax withheld: $3,720 (6.2%).
• Second Company (July 31 - Dec 31): Your pay statement shows YTD earnings of $41,880.89 (excluding RSUs), with Social Security tax withheld of $9,856.61 YTD. Including RSUs ($321,171.72), your total wages are $362,052.61, but Social Security tax only applies to the first $168,600.
• Total Withheld: $3,720 (first company) + $9,856.61 (second company) = $13,576.61.
• Over-Withholding: You should only pay $10,453.20. The excess is $13,576.61 - $10,453.20 = $3,123.41.

3.2. Unemployment Period (May 3 - July 31)

• Unemployment Benefits: If you received unemployment benefits during this period, they’re taxable as ordinary income (Form 1099-G) but not subject to Social Security tax.
• Impact: This period doesn’t affect Social Security withholding but increases your taxable income if benefits were received.

3.3. Reclaiming Over-Withheld Tax

• Federal Return: On Form 1040, Line 25a, report total Social Security tax withheld ($13,576.61). The IRS will calculate your refundable credit for the excess ($3,123.41) as part of your refund (Line 34).
• CA Return: CA doesn’t tax Social Security benefits, so this over-withholding doesn’t affect your state return.

3.4. Strategies

• Coordinate with Employers: Request a refund of excess withholding from the second employer (they can adjust payroll). If not, claim it on your return.
• Monitor Future Withholding: Since you’ve maxed out Social Security tax, ensure the second employer stops withholding for the rest of 2024.

3.5. Compliance

• W-2s: Verify both W-2s (Box 4) reflect the correct Social Security tax withheld.
• Form 1040: Ensure the excess is claimed correctly to avoid delays in your refund.

4. Capital Tax When a Loss Occurred

4.1. Scenario

Assume you sold investments (e.g., stocks) in 2024 at a loss. For example, you bought stock for $50,000 and sold it for $40,000, incurring a $10,000 capital loss.

Tax Treatment

• Capital Loss: Report on Schedule D and Form 8949. The $10,000 loss can offset capital gains.
• Offsetting Gains: If you sold RSU shares for a $28,828.28 gain (as discussed), the $10,000 loss reduces your taxable gain to $18,828.28.
• Deduction Against Ordinary Income: If you have no gains, you can deduct up to $3,000 of the net capital loss against ordinary income (e.g., RSU income). The remaining $7,000 carries forward to 2025.
• NIIT: Losses reduce your net investment income, lowering your NIIT liability (e.g., on Airbnb income).

4.2. Strategies

• Harvest Losses: Sell other losing investments to offset RSU gains, reducing your tax liability.
• Carryforward: Use the $7,000 loss in future years to offset gains or income.
• Wash Sale Rule: Avoid repurchasing the same stock within 30 days, or the loss is disallowed (IRC Section 1091).

4.3. Compliance

• Form 1099-B: Use your broker’s 1099-B to report the sale.
• Schedule D: Calculate net gain/loss and carryforward.

5. Vehicle Transportation: 8,000 Out of 16,000 Miles for Commuting

5.1. Commuting Miles

You drove 16,000 miles total in 2024, with 8,000 miles for commuting between home and work. Unfortunately, commuting miles are not deductible for W-2 employees (per the Tax Cuts and Jobs Act, 2017-2025).

Tax Treatment

• Non-Deductible: The 8,000 commuting miles don’t qualify for a deduction, even at the 2024 standard mileage rate (~67 cents/mile).
• Other Miles: The remaining 8,000 miles might be deductible if they’re for business purposes (e.g., self-employment, Airbnb).

5.2. Business Use (Self-Employment/Airbnb)

Assume 4,000 of the remaining 8,000 miles were for your self-employment (e.g., house flipping) and 2,000 for Airbnb (e.g., buying supplies).

• Self-Employment: 4,000 miles x 67 cents = $2,680, deductible on Schedule C.
• Airbnb: 2,000 miles x 67 cents = $1,340, deductible on Schedule E (Line 6, “Auto and Travel”).

5.3. Strategies

• Track Business Miles: Use a mileage log app (e.g., MileIQ) to document business miles.
• Alternative Deduction: If actual expenses (gas, maintenance) exceed the standard rate, deduct those instead (prorated for business use).

5.4. Compliance

• Documentation: Keep a detailed log (date, purpose, miles) to substantiate deductions.
• Schedule C/E: Report mileage deductions accurately.

6. Airbnb Operation Loss (Income Minus Expenses)

6.1. Scenario

Your Airbnb income was $20,000, but expenses totaled $25,000 (e.g., mortgage interest, utilities, depreciation, $5,000 in devices), resulting in a $5,000 loss.

Tax Treatment

• Schedule E: Report income ($20,000) and expenses ($25,000) on Schedule E, resulting in a $5,000 loss.
• Passive Activity Loss Rules: Airbnb is typically a passive activity. Losses are limited to $25,000 if AGI is under $100,000 (phased out by $150,000). Your AGI ($426,521.72 after adjustments) exceeds this, so the loss is suspended.
• Real Estate Professional (REP): If you spend >750 hours and >50% of your work in real estate, the loss becomes non-passive, fully deductible against your RSU income.

6.2. Strategies

• Claim REP Status: Log your hours to qualify as an REP, allowing the $5,000 loss to offset other income.
• Carryforward: If not deductible, carry the loss forward to offset future rental income.
• Reduce MAGI: Lower your AGI with 401(k)/HSA contributions to potentially deduct more of the loss.

6.3. Compliance

• Form 8582: Calculate allowable passive losses.
• Time Logs: Document REP hours if claiming that status.

7. Gift Tax on $6,000 Given to Retired Father

7.1. Tax Treatment

You gave your retired father $6,000 in 2024. In the U.S., the donor (you) is responsible for gift tax, not the recipient.

Annual Exclusion

• 2024 Exclusion: Likely $18,000 per recipient (adjusted from 2023’s $17,000).
• Your Gift: $6,000 is below the exclusion, so no gift tax or reporting is required.

Lifetime Exemption

• If the gift exceeded $18,000, it would reduce your lifetime gift/estate tax exemption (~$13.61 million in 2024), but $6,000 doesn’t trigger this.

7.2. Impact on Father

• Not Taxable: Gifts are not taxable income to the recipient (IRC Section 102). Your father doesn’t report the $6,000 on his Form 1040.

7.3. Strategies

• Stay Under Exclusion: Keep gifts under $18,000 per person to avoid reporting.
• Splitting Gifts: If married, you and your spouse can give $36,000 per recipient without reporting.

7.4. Compliance

• No Action: Since $6,000 is below the threshold, no Form 709 (Gift Tax Return) is required.

8. Tax on Undocumented Cash Purchases ($5,000 Total) for Airbnb Devices

8.1. Scenario

You spent $5,000 in cash (no receipts) on used devices (e.g., TVs, fitness equipment) for Airbnb guests through an online market.

Tax Treatment

• Deductible Expense: These are ordinary and necessary expenses for your Airbnb business, deductible on Schedule E (Line 15, “Supplies,” or Line 19, “Other”).
• De Minimis Safe Harbor: If each item/invoice is $2,500 or less, expense the full $5,000 in 2024 (Reg. §1.263(a)-1(f)). If over $2,500 (e.g., one $3,000 TV), depreciate over 5 years (MACRS, ~$600 in Year 1).
• Lack of Receipts: The IRS requires substantiation, but the Cohan Rule allows reasonable estimates if you lack documentation. Document the purchase (date, amount, purpose) and take photos of the devices in use.

8.2. Strategies

• Reconstruct Records: Write a log: “June 2024, bought used TV and weights for $5,000 cash via online market for Airbnb guests.” This supports your deduction.
• Pro-Rate: If you use the devices personally, pro-rate the deduction (e.g., 200 rental days / 365 = 55%, so $2,750 deductible).
• Audit Prep: Keep photos and bank withdrawal records (if applicable) to show good faith.

8.3. Compliance

• Schedule E: Report the $5,000 (or pro-rated amount) as an expense.
• Form 4562: If depreciating, calculate Year 1 depreciation.
