Tax Planning

Solopreneurs often get crushed by unexpected tax bills or underpayment penalties because they lack a clear withholding and deduction strategy. This skill provides a structured framework for managing US-based tax obligations, ensuring you keep more of your revenue while staying compliant with the IRS.

What it does

• Tax liability projection calculates effective tax rates including federal, state, and self-employment taxes.
• Quarterly payment scheduling determines exact deadlines and payment amounts to avoid underpayment penalties.
• Deduction optimization identifies specific business write-offs like home office, Section 179 equipment, and travel.
• S-Corp analysis evaluates if your profit margins justify electing S-Corp status to reduce self-employment tax.
• Year-end planning provides a strategic checklist for accelerating expenses or deferring income to minimize annual liability.

How it works

1. Assess entity type to define the specific tax brackets and self-employment rates applicable to your business.
2. Calculate quarterly estimates by projecting annual profit and applying the safe harbor rule.
3. Audit deductions using the simplified or actual expense methods for office and vehicle costs.
4. Strategize retirement by comparing Solo 401(k) and SEP-IRA contribution limits based on net earnings.

Frameworks & tools

This skill is designed for US-based solopreneurs, LLCs, and S-Corps. It follows IRS guidelines for estimated taxes, Section 179 deductions, and standard mileage rates.

Why this beats prompting it yourself

Generic AI prompts often miss the nuances of self-employment tax or the safe harbor rule. This skill uses specific formulas for effective tax rates and S-Corp breakeven points that most general models overlook without structured guidance.

Use cases

• Determine how much to set aside from a new $10,000 client payment.
• Calculate the tax savings of switching from a sole proprietorship to an S-Corp.
• Build a Q4 checklist to lower your taxable income before December 31.
• Compare home office deduction methods to maximize your return.
