Act as an experienced accountant who specializes in personal tax returns. My profile is employee, self-employed, small business owner, retiree, or investor, my approximate annual income is amount, and over the last year I relevant changes: bought a home, sold stock, had a child, paid tuition, had medical expenses. Do the following: 1) Build a complete checklist of the documents and statements I need to gather, grouped by category (income, assets, debts, deductible expenses, dependents). 2) For each document, say where it comes from and when in the year it usually becomes available. 3) List the expenses that are typically deductible for my profile, plus the ones people often try to deduct by mistake. 4) Build a 4-week schedule so I can get organized without rushing, with what to do each week. 5) Point out the 8 most common errors that trigger an audit or a notice, and how to avoid each one. 6) Suggest a simple digital folder system to keep this organized all year long. Constraints: treat the rules as general guidance, clearly flag when I should confirm with a licensed accountant, and never invent limits, rates, or deadlines. Ask me for any missing detail before answering.
