The Solopreneur Tax Strategy Playbook

Read this first

This guide is educational. It is not tax, legal, payroll, retirement-plan, or investment advice. The right answer depends on entity type, state law, income level, family facts, payroll setup, plan documents, deadlines, and whether the records can support the position.

The recurring theme is simple: tax strategy starts before the tax return. If your bank feeds, cards, owner draws, reimbursements, contractor payments, and payroll are not clean, the best strategies either get missed or get implemented weakly.

Quick score: are you ready for strategy?

If you checked fewer than three boxes, your first tax strategy is monthly bookkeeping. Without current books, every other strategy becomes slower, weaker, or more expensive.

1. Paying your kids through the business

This can be a real planning idea, but it is not a magic transfer. The child needs a real job, reasonable pay for the work, time records, actual payment, and payroll treatment that matches the entity.

IRS Publication 15 says payments to a child under age 18 working for a parent's sole proprietorship or a partnership where each partner is a parent are not subject to Social Security and Medicare taxes; different rules apply for corporations and other structures.

Clearclose angle: we keep the books clean enough to show the labor expense, payment trail, and monthly records before year-end planning happens.

2. Solo 401(k): the savings example owners actually care about

A solo 401(k) can be powerful because the owner may have both employee deferral and employer contribution layers. The specific amount depends on earned income, plan design, timing, age, entity type, and other retirement plans.

Clearclose angle: monthly books make the contribution conversation possible before the deadline, while payroll and owner draws are still fixable.

3. Is an S election right for you?

An S election can reduce self-employment-tax exposure for some profitable owners, but it adds payroll, separate entity compliance, stricter compensation discipline, and more year-round administration.

The IRS says S corporations must pay reasonable compensation to shareholder-employees for services before non-wage distributions are made. That means the wage decision is part of the tax strategy, not a year-end guess.

Clearclose angle: we separate wages, draws, reimbursements, and expenses in QBO so the S-election analysis has numbers behind it.

4. Optimizing W-2 wages you pay yourself

For S-corp owners, the question is not "How low can the salary be?" The better question is "What compensation is defensible, supports the retirement plan, fits cash flow, and still leaves room for distributions?"

• Too low can create payroll-tax and audit risk.
• Too high can shrink distribution planning and retirement flexibility.
• Late payroll setup makes the whole year harder to correct.
• Books should show wages, payroll taxes, reimbursements, and owner distributions clearly.

5. Accountable plans and owner reimbursements

If an S-corp owner pays business expenses personally, reimbursements can become messy. Accountable-plan treatment generally requires a business connection, adequate accounting, and return of excess reimbursements within a reasonable period.

The practical habit: submit monthly reimbursement reports with receipts, mileage logs, and home-office support where applicable. Record the reimbursement in QBO instead of leaving personal-card charges scattered across the year.

Clearclose angle: monthly close questions catch reimbursement issues while receipts and explanations are still available.

6. Home office, storage, and the deduction owners skip or overclaim

Home office is not advanced, but the way it interacts with entity type and reimbursements can be. The IRS exclusive-use rule is strict, with exceptions for inventory/product sample storage and daycare facility use.

A Schedule C filer may compute the deduction directly. An S-corp owner usually needs a cleaner reimbursement approach because the corporation, not the shareholder personally, is the business entity.

7. Self-employed health insurance and HSA coordination

The self-employed health insurance deduction is not just "medical expenses." The IRS uses Form 7206 to determine the amount of self-employed health insurance deduction that may be claimed and reported on Schedule 1.

This area gets fact-specific fast: plan ownership, business income, marketplace coverage, spouse coverage, S-corp wage reporting, and HSA eligibility can all change the answer.

8. QBI: the pass-through deduction that should be modeled, not assumed

The qualified business income deduction can allow eligible pass-through owners to deduct up to 20% of qualified business income, subject to limits. IRS 2026 update pages also note that the QBI deduction was made permanent.

QBI interacts with retirement contributions, self-employed health insurance, self-employment tax, W-2 wages, specified service trade or business limits, and taxable income. That is why "maximize deductions" is not always the whole answer.

9. Estimated tax is cash-flow planning, not punishment

Self-employed owners often wait until a tax return tells them they are behind. The IRS FAQ says estimated payments can cover estimated income tax and self-employment tax.

Current books let you review quarterly profit, owner draws, payroll withholding, retirement funding, and the tax reserve before the year gets away from you.

10. Better deductions than the same five Google results

The IRS baseline is that business expenses must be ordinary and necessary: common and accepted in the field, and helpful or appropriate for the business.
