When to Use

Use this skill when:

• User wants to set up a system to track tax deductions throughout the year
• User asks what expenses might be deductible
• User needs to organize documentation for tax-deductible expenses
• User wants a template for categorizing potential deductions
• User asks how to document expenses for tax purposes

Do NOT use this skill when:

• User wants to file their taxes (use tax-filing-prep)
• User needs to estimate quarterly tax payments (use quarterly-tax-estimator)
• User wants to understand tax-advantaged accounts (use tax-advantaged-optimizer)
• User wants specific tax advice for their situation (consult a tax professional)

Process

1. Identify the user's deduction context. Determine:

   • Filing status: Are they employed (W-2), self-employed, or both?
   • Itemizing vs. standard: Do they itemize deductions or take the standard deduction? [JURISDICTION: verify current standard deduction amounts and when itemizing makes sense]
   • Major deduction categories applicable: Based on their situation, identify which categories to track
   • Current tracking method: Are they starting from scratch or improving an existing system?

2. Build the deduction category framework. Present the common deduction categories. For each category, provide:

   • What qualifies [JURISDICTION: verify your country/state eligibility rules]
   • Documentation required to substantiate the deduction
   • Whether there is a cap or phase-out [JURISDICTION: verify current limits]
   • Tracking method recommendation

   Category 1: Medical and Health Expenses

   • Unreimbursed medical expenses above a percentage of adjusted gross income [JURISDICTION: verify the AGI threshold percentage]
   • Documentation: Receipts, insurance Explanation of Benefits (EOB), pharmacy records
   • Track: Date, provider, description, amount paid, insurance reimbursement received

   Category 2: Charitable Contributions

   • Cash donations to qualified organizations
   • Non-cash donations (clothing, goods) at fair market value
   • Documentation: Receipts, acknowledgment letters for donations above threshold [JURISDICTION: verify receipt requirements and limits]
   • Track: Date, organization, type (cash/goods), amount or estimated value

   Category 3: State and Local Taxes (SALT)

   • State income taxes or sales taxes paid
   • Local property taxes
   • [JURISDICTION: verify deductibility limits and caps on SALT deductions]
   • Documentation: Tax returns, property tax bills, pay stubs showing state tax withheld

   Category 4: Mortgage Interest

   • Interest paid on a qualifying mortgage [JURISDICTION: verify loan amount limits for deductibility]
   • Points paid on a mortgage origination
   • Documentation: Annual mortgage interest statement from lender
   • Track: Monthly payment breakdown showing interest portion

   Category 5: Education Expenses

   • Tuition and fees [JURISDICTION: verify which education expenses qualify as deductions vs. credits]
   • Student loan interest [JURISDICTION: verify deduction limits and income phase-outs]
   • Documentation: Tuition statements, student loan interest statements

   Category 6: Business and Self-Employment Expenses (if applicable)

   • Business supplies, equipment, software
   • Professional development and industry memberships
   • Business travel, meals (at deductible percentage) [JURISDICTION: verify deductible percentages]
   • Home office expenses [JURISDICTION: verify home office qualification rules]
   • Documentation: Receipts, mileage logs, home office measurements

   Category 7: Investment-Related Deductions

   • Investment management fees [JURISDICTION: verify if currently deductible]
   • Tax preparation fees [JURISDICTION: verify if currently deductible]
   • Documentation: Fee statements, invoices from tax professionals

   Category 8: Job-Related Expenses (if applicable)

   • Unreimbursed employee expenses [JURISDICTION: verify if currently deductible -- rules vary significantly]
   • Professional licenses and certifications
   • Union dues
   • Documentation: Receipts, employer non-reimbursement documentation

3. Create the tracking template. For each applicable category, build a tracking spreadsheet structure:

   • Date of expense
   • Category and subcategory
   • Vendor or payee
   • Description of expense
   • Amount
   • Documentation status (receipt collected: yes/no)
   • Notes (reimbursement status, special circumstances)

4. Set up the documentation system. Advise on organizing supporting documents:

   • Digital filing: One folder per category, named by year
   • Receipt capture: Photograph or scan receipts immediately (paper fades)
   • Monthly reconciliation: Review tracked expenses against bank/credit card statements
   • Annual summary: Total by category before filing

5. Establish a review schedule. Build a recurring process:

   • Weekly: Log new expenses, capture receipts
   • Monthly: Reconcile against statements, verify documentation completeness
   • Quarterly: Review category totals, identify missing documentation
   • Year-end: Final reconciliation, prepare totals for filing

6. Present the itemization threshold analysis. Help the user understand whether tracking matters for their situation:

   • Compare their expected total deductions against the standard deduction [JURISDICTION: verify current standard deduction for their filing status]
   • Note that tracking is valuable even if they take the standard deduction -- they may cross the itemization threshold unexpectedly
   • Self-employment deductions are separate from the itemize vs. standard decision

### Important Reminders

Rules

1. NEVER state specific deduction amounts, limits, or thresholds as facts -- always use [JURISDICTION: verify] placeholders
2. NEVER advise whether to itemize or take the standard deduction -- present the comparison framework
3. NEVER provide tax filing instructions -- this skill builds the tracking system, not the return
4. ALWAYS include documentation requirements for every deduction category
5. ALWAYS remind the user to verify eligibility rules with their jurisdiction's official source
6. Include both the standard deduction comparison and the tracking template
7. Include a review schedule with weekly, monthly, quarterly, and annual checkpoints
8. Mark every jurisdiction-specific detail with [JURISDICTION: ...] placeholder
9. If the user is self-employed, include both personal and business deduction categories
10. Note that tracking deductions is valuable even if the user takes the standard deduction

Edge Cases

• User does not know if they should itemize: Build the tracking system for all potential categories. At year-end, the totals will reveal whether itemizing exceeds the standard deduction. Tracking costs nothing; missing deductions costs money.
• User is self-employed: Self-employment deductions (business expenses) are deducted differently from personal itemized deductions [JURISDICTION: verify where business deductions are claimed]. Build separate tracking sections for personal and business expenses.
• User has income from multiple jurisdictions: Note that state and local deduction rules vary by jurisdiction. The tracking system should tag each expense with the relevant jurisdiction. Recommend consulting a tax professional who handles multi-state situations.
• User is new to tracking and overwhelmed: Start with the three largest categories likely to apply (charitable, medical, business/job expenses). Add categories in future months as the habit develops. A partial tracking system is better than none.
• User asks about audit protection: Note that documentation is the primary defense in an audit. The tracking system with receipts and records serves this purpose. [JURISDICTION: verify record retention requirements -- typically several years minimum].
• Mid-year start: Reconstruct year-to-date expenses from bank and credit card statements. Digital records make this feasible. Focus on large expenses first and fill in smaller ones as time allows.

Example

Input: "I'm self-employed and want to set up a system to track my tax deductions this year. I work from home and drive to client meetings."
