Employment Type Awareness

Read USER.md to detect employment type. If unclear, ask the user. Tailor all advice to their situation:

W-2 Employee

• Focus: Above-the-line deductions (401k, Traditional IRA, HSA), retirement maximization, charitable giving, investment loss harvesting
• Home office deduction: NOT available for W-2 employees (TCJA suspended 2018–2025; verify annually if restored)
• Maximize employer benefits: 401k match, HSA, FSA, ESPP
• Review W-4 withholding annually
• Standard deduction vs. itemized analysis

Self-Employed / 1099 Contractor

• Focus: Schedule C deductions, SE tax (15.3%), QBI deduction (Section 199A), home office, business expenses, estimated quarterly payments
• Self-employment tax deduction (50% of SE tax, above-the-line)
• Solo 401(k) or SEP-IRA for retirement
• Health insurance premiums (100% deductible above-the-line if no employer plan available)
• Must make quarterly estimated tax payments

S-Corp Owner

• Reasonable salary + distributions strategy (save SE tax on distributions)

• Schedule C for side business; W-2 income on main return
• Business losses offset W-2 income dollar-for-dollar
• Track business vs. personal use percentages for shared assets
• Must show profit in 3 of 5 years to avoid hobby loss classification
• Estimated payments needed for business income (W-2 withholding may cover if adjusted)

Tax Strategies & Loopholes

Timing Strategies

• Bunch deductions: Alternate between standard and itemized deductions year-to-year. Bunch charitable giving and medical expenses into one year to exceed the standard deduction threshold.
• Accelerate expenses: Buy business equipment before Dec 31 to deduct in current year (Section 179)
• Defer income: If possible, push income into next year to lower current-year tax bracket
• Harvest losses: Sell losing investments before year-end to offset capital gains (watch wash sale rule — 30 days)

Section 179 & Bonus Depreciation

• Section 179: Deduct full cost of qualifying business equipment in year purchased (up to $1,220,000 for 2025 — check annually)
• Covers: computers, office furniture, software, vehicles (with limits), business equipment
• Heavy vehicles (GVWR > 6,000 lbs): Full purchase price eligible (no luxury vehicle cap)
• Bonus depreciation: Phasing down — 40% for 2025, 20% for 2026, 0% for 2027+ (unless extended by Congress)
• Applies to new AND used property
• Personal assets converting to business use: depreciable basis = LESSER of original cost OR FMV at conversion date

Augusta Rule (Section 280A)

• Rent your home for 14 days or fewer per year — income is TAX-FREE
• If you own a business, rent your home to your business for meetings/events
• Must charge fair market rate, document everything
• Business deducts the rent, you receive it tax-free

Home Office Deduction

• ONLY for self-employed / 1099 income — W-2 employees CANNOT claim (TCJA suspended 2018–2025; check if restored for 2026+)
• The IRS confirms: available for "homeowners and renters, all types of homes" including RVs that qualify as a home
• Simplified method: $5/sqft, max 300sqft = $1,500/year. Easy, no depreciation recapture.
• Actual method: Percentage of mortgage/rent, utilities, insurance, repairs, depreciation. More work but usually bigger deduction.
• Must be "regular and exclusive" use for business
• Must be your "principal place of business"
• ⚠️ Always verify current year rules at irs.gov — tax law changes frequently

QBI Deduction (Section 199A)

• 20% deduction on qualified business income for pass-through entities
• Available if taxable income below $191,950 (single) / $383,900 (married) — check annually
• Applies to: sole proprietors, S-corps, partnerships, LLCs
• Specified service businesses (consulting, financial services) phase out at income limits

Entity Structure Optimization

• S-Corp election: Pay yourself "reasonable salary" + take remaining profits as distributions (avoid SE tax on distributions)
• Generally beneficial when SE income exceeds ~$50–60k
• Must file Form 2553
• Adds complexity: payroll, separate return

Roth Conversion Ladder

• Convert Traditional IRA to Roth in low-income years
• Pay tax now at lower rate, grow tax-free forever
• "Backdoor Roth" for high earners: non-deductible Traditional IRA → convert to Roth
• Watch pro-rata rule if you have existing Traditional IRA balances

Mega Backdoor Roth

• After-tax 401(k) contributions → in-plan Roth conversion
• Can contribute up to $70,000 total (2025) including employer match
• Only works if employer plan allows after-tax contributions + in-service distributions

Charitable Strategies

• Donor-Advised Fund (DAF): Bunch multiple years of giving into one year, get immediate deduction, distribute to charities over time
• Appreciated stock: Donate stock held 1yr+ directly to charity. Deduct FMV, avoid capital gains entirely.
• QCD (Qualified Charitable Distribution): Age 70½+, donate up to $105,000 directly from IRA to charity. Counts toward RMD, excluded from income.

State-Specific

• No state income tax states: TX, FL, NV, WA, WY, SD, AK, NH (interest/dividends only), TN (no wage tax)
• SALT cap workaround: Some states allow pass-through entity tax election (entity pays state tax, gets federal deduction, bypasses $10k SALT cap)

Proactive Monthly Nudges

When the tax-professional skill is consulted or during heartbeat checks, consider time-of-year context:

Tax Bracket Optimization

2025 Federal Tax Brackets (Single Filer)

(Update bracket thresholds annually — they adjust for inflation.)

Bracket Strategies

• Identify current bracket: Based on estimated taxable income (AGI − deductions)
• Optimize around thresholds: "You're $X away from the next bracket — a Traditional IRA contribution / additional 401k / business expense would keep you in the lower bracket"
• Roth conversion planning: Fill up the current bracket with Roth conversions (convert just enough to stay in current bracket, pay tax at known rate, grow tax-free)
• Capital gains brackets: Long-term capital gains taxed at 0% (up to ~$48k single), 15% (up to ~$533k), 20% above that. Plan sales around these thresholds.
• Income smoothing: If income varies year-to-year, accelerate deductions in high-income years, defer to low-income years

Estimated Tax Calculator

When Estimated Payments Are Required

• Expect to owe $1,000+ in tax after withholding and credits
• Self-employment income, investment income, rental income, etc.
• Penalty-free if you meet safe harbor rules

Safe Harbor Rules

• Pay 100% of prior year's tax liability through withholding + estimated payments — no penalty regardless of current year income
• 110% rule: If AGI exceeds $150,000 ($75,000 MFS), must pay 110% of prior year's tax
• Alternative: Pay 90% of current year's tax liability
• Meet either threshold to avoid underpayment penalty (Form 2210)

Calculation Method

1. Estimate current year total income (W-2 + 1099 + investments + other)
2. Subtract above-the-line deductions (401k, IRA, HSA, SE tax deduction, etc.)
3. Subtract standard deduction or estimated itemized deductions
4. Apply tax brackets to get estimated tax
5. Subtract W-2 withholding and credits
6. Divide remaining tax by 4 for quarterly payments
7. Compare against safe harbor amount — pay whichever strategy is preferred

Track Estimated Payments

Log in the expense file under estimatedPayments array:

{
  "quarter": "Q1",
  "dueDate": "YYYY-04-15",
  "amount": 2500,
  "paid": true,
  "datePaid": "YYYY-04-10",
  "confirmationNumber": "EFTPS-12345"
}

Audit Risk Assessment

Audit Red Flags 🚩

Documentation Levels

Low-Risk Deductions (standard records):

• W-2 withholding, standard deduction, basic retirement contributions
• Keep: W-2s, 1099s, contribution statements
• Standard recordkeeping is sufficient

Medium-Risk Deductions (detailed records + contemporaneous notes):

• Home office, vehicle expenses, business meals, charitable giving
• Keep: Receipts, mileage log (daily), home office measurements/photos, meal logs with business purpose
• Contemporaneous notes (recorded at or near the time of the expense)

High-Risk Deductions (professional documentation, appraisals):

• Large non-cash charitable donations (>$5,000 requires qualified appraisal)
• Section 179 on vehicles, business use of personal assets, entity structure deductions
• Keep: Professional appraisals, detailed business plans, formal agreements, photos/documentation of business use
• Consider professional tax preparer review

General Documentation Best Practices

• Receipt rule: Keep receipts for everything >$75 (IRS requirement). Best practice: keep ALL business receipts.
• Contemporaneous logs: Mileage, meals, and home office use should be logged when they happen, not reconstructed later
• Business purpose: Always document WHY an expense is business-related
• Photographic evidence: Home office setup, business equipment, vehicle condition
• Separate accounts: Use a dedicated business bank account and credit card

Life Event Tax Triggers

When the user mentions a life event, proactively walk through tax implications:

Marriage / Divorce

• Filing status change: Married Filing Jointly (usually best), Married Filing Separately, or back to Single
• Name change: Update SSA (Form SS-5) before filing
• Asset transfers: Transfers between spouses during marriage are tax-free (IRC §1041)
• Divorce: Property division is generally tax-free; alimony rules depend on divorce date (pre-2019: deductible by payer/income to recipient; post-2018: no tax effect)
• Review withholding: Immediately update W-4 after status change

New Baby / Dependent

• Child Tax Credit: Up to $2,000 per qualifying child (check phase-out at $200k single / $400k married)
• Dependent Care FSA: Up to $5,000/year pre-tax for childcare
• 529 Plan: State tax deduction for contributions (varies by state)
• Head of Household: If unmarried with qualifying dependent — lower tax rates than Single
• EITC: If income qualifies, Earned Income Tax Credit is significant

Home Purchase / Sale

• Purchase: Mortgage interest deduction (up to $750k loan), property tax deduction (SALT cap $10k), points paid at closing may be deductible
• Sale: Capital gains exclusion — $250k single / $500k married (must live in home 2 of last 5 years)
• Home office: If you have a home office, portion of home sale may not qualify for exclusion (depreciation recapture)

Job Change

• 401(k) rollover: Roll old employer 401k into new employer plan or IRA. Do NOT cash out (10% penalty + income tax).
• Moving expenses: Not deductible for most taxpayers (TCJA suspended; only active military)
• Review withholding: Immediately update W-4 at new employer
• Negotiate: Sign-on bonus, relocation reimbursement, equity vesting schedule — all have tax implications
• Gap in employment: If between jobs, may have lower income year — opportunity for Roth conversion

Retirement

• RMDs (Required Minimum Distributions): Must begin at age 73 (SECURE 2.0 Act). Failure penalty: 25% of amount not withdrawn (reduced to 10% if corrected timely).
• Social Security taxation: Up to 85% of benefits may be taxable depending on combined income
• Medicare IRMAA surcharges: If income exceeds threshold (>$103k single, >$206k married), Medicare Part B and D premiums increase. Income is based on 2-year lookback.
• Roth conversions before RMDs: Strategic opportunity to convert in lower-income years before RMDs begin

Death of Spouse

• Surviving spouse filing status: Can file jointly for year of death; qualifying surviving spouse status for 2 years after if you have a dependent child
• Stepped-up basis: Inherited assets get cost basis stepped up to FMV at date of death (huge tax benefit)
• Estate tax: Federal exemption ~$13.6 million (2025). Most estates not affected. Check state estate/inheritance tax.
• Beneficiary designations: Review all retirement accounts, life insurance, bank accounts

Starting a Business

• Entity selection: Sole prop (simplest), LLC (liability protection), S-Corp (tax optimization) — see Entity Structure section
• EIN: Apply for free at irs.gov (instant online)
• Estimated payments: Required from day one if you expect to owe $1,000+
• Home office: Immediately deductible if you have a dedicated space
• Startup costs: First $5,000 deductible immediately; excess amortized over 15 years
• Business bank account: Open immediately to separate personal and business finances

Moving to a New State

• Residency rules: Most states define resident as living there 183+ days. Some use domicile (intent to remain).
• Multi-state filing: May need to file part-year returns in both old and new state
• Income allocation: W-2 income typically taxed by state where work is performed; business income may be apportioned
• Moving date matters: Moving mid-year means filing in both states
• No income tax states: Moving to TX, FL, NV, WA, WY, SD, AK eliminates state income tax

Multi-State Filing Awareness

When Multi-State Filing Is Required

• Lived in more than one state during the year
• Earned income in a state other than your resident state
• Work remotely for employer in a different state (some states claim taxing authority)
• Own rental property or business income in another state

Key Concepts

• Domicile: Your permanent home — where you intend to return. Only one domicile at a time.
• Residency: Where you physically live. Can be "resident" of one state and "statutory resident" of another (usually 183+ days).
• Source income: Income earned within a state's borders (work performed there, property located there, business operated there)
• Credits: Most states give credit for taxes paid to other states on the same income (avoid true double taxation)

States with No Income Tax

Alaska, Florida, Nevada, New Hampshire (interest/dividends only), South Dakota, Tennessee, Texas, Washington, Wyoming

Reciprocity Agreements

Some neighboring states have agreements where you only pay tax to your home state (e.g., VA/DC/MD, IL/IN/IA/KY/MI/WI). Check if your states have reciprocity.

Allocation and Apportionment

• W-2 income: Usually apportioned by days worked in each state
• Business income: May use sales factor, payroll factor, or property factor depending on state
• Investment income: Generally taxed only by resident state

Full-Time RVer Considerations

• Must establish domicile in one state (driver's license, voter registration, vehicle registration, mail forwarding address)
• That state is your resident state for tax purposes
• If you work while traveling through other states, technically may owe tax to those states (enforcement varies)
• Popular domicile states for RVers: South Dakota, Texas, Florida (no income tax + easy residency)

RV-as-Home Tax Rules

An RV qualifies as a "home" for federal tax purposes if it has sleeping, cooking, and toilet facilities. This opens several deductions:

Mortgage Interest Deduction

• If the RV is financed, loan interest may be deductible as home mortgage interest
• RV can be your primary residence or second home
• Subject to the $750,000 mortgage limit (combined across all qualified homes)
• Report on Schedule A (itemized deductions)

Home Office in RV

• Same rules as traditional home office: regular and exclusive use as your principal place of business
• Simplified method: $5/sqft, max 300sqft = $1,500
• Actual method: percentage of RV costs (loan interest, insurance, park fees, utilities, maintenance, depreciation)
• Only available for self-employed / 1099 income — not W-2 employees

Property Tax on RV

• May be deductible as personal property tax (not real property tax)
• Varies by state and county — some jurisdictions assess personal property tax on RVs, some don't
• Vehicle license tax (ad valorem portion) may qualify as deductible personal property tax
• Subject to SALT cap ($10,000 combined state/local/property)

Full-Time RVer Special Considerations

• Domicile state: Must establish legal domicile (driver's license, voter registration, mail forwarding)
• Mail forwarding services: Available in SD, TX, FL — these states also have no income tax
• Voter registration: Register in domicile state
• Insurance: Must match domicile state
• Health insurance: ACA marketplace based on domicile ZIP code
• Business address: Use domicile address or registered agent for business filings

Document Retention Guide

How Long to Keep Tax Records

Digital Record Keeping Tips

• Scan all paper receipts and store digitally (paper fades)
• Organize by year and category
• Back up to cloud storage
• Save bank/credit card statements (backup documentation)
• Screenshot or save digital receipts (email confirmations, app purchases)

Integration Hooks

Mechanic Skill Integration

When the mechanic skill (skills/mechanic/SKILL.md) logs a vehicle service:

• If the vehicle has business_use: true or a business_use_percent > 0 in data/mechanic/state.json, the maintenance expense is deductible
• Deductible amount = cost × business_use_percent (if using actual expense method)
• NOT separately deductible if using standard mileage rate (already included in rate)
• The mechanic skill should suggest logging deductible portions to data/tax-professional/YYYY-expenses.json

Card Optimizer Integration

• Purchase categories from skills/card-optimizer/SKILL.md can help identify potentially deductible expenses
• Business purchase categories: office supplies, software, travel, gas, internet
• Cross-reference data/card-optimizer/cards.json for spending category analysis

Data Paths

• Tax profile: data/tax-professional/tax-profile.md (user's tax-relevant info: filing status, employment, deductions)
• Tax expenses: data/tax-professional/YYYY-expenses.json
• Tax return analyses: data/tax-professional/YYYY-return-analysis.md
• Mechanic state: data/mechanic/state.json
• Card data: data/card-optimizer/cards.json

Staying Current

⚠️ Tax law changes frequently. Before applying any strategy:

1. Verify current-year rules at irs.gov
2. Check if TCJA provisions have been extended, modified, or expired
3. Confirm current year's standard deduction, mileage rates, contribution limits
4. Search for "[deduction name] [current year] IRS" to get latest guidance

Key rates to verify annually:

• Standard mileage rate (business, charity, medical)
• Standard deduction amount
• Tax bracket thresholds (adjust for inflation annually)
• Retirement contribution limits (401k, IRA, HSA)
• Section 179 expense limit
• Bonus depreciation percentage (phasing down: 60%→40%→20%→0%)
• SALT deduction cap (currently $10,000 — may change)
• Child Tax Credit amount and phase-out thresholds
• QBI deduction income thresholds
• Estate tax exemption amount

Important Disclaimers

⚠️ This is educational guidance, not professional tax advice. Always confirm major decisions with a licensed CPA or tax attorney.

Key rules:

• Keep receipts for everything over $75 (IRS documentation requirement)
• Keep receipts for ALL business expenses regardless of amount (best practice)
• Maintain a contemporaneous log for mileage, meals, and home office
• Business expenses must be "ordinary and necessary" for your trade
• Personal expenses are NEVER deductible — mixed-use items need allocation
• The IRS looks at "substance over form" — must have legitimate business purpose
