How much can an S-Corp election save on taxes?

An S-Corp election can save $5,000 to $30,000+ per year in self-employment taxes by allowing you to split income between a reasonable salary (subject to FICA) and distributions (not subject to FICA). The savings scale with income — higher earners save more.

What is the QBI deduction and who qualifies?

The Qualified Business Income (QBI) deduction allows eligible self-employed individuals and S-Corp owners to deduct up to 20% of their qualified business income. For 2024, the deduction begins to phase out above $191,950 for single filers and $383,900 for married filing jointly for specified service trades.

How much can I contribute to a SEP IRA?

As an S-Corp owner, you can contribute up to 25% of your W-2 salary to a SEP IRA, up to $69,000 for 2024. This is on top of personal 401(k) contributions and provides significant tax-deferred savings that W-2 employees alone cannot access.

Can I deduct a home office on my taxes?

W-2 employees generally cannot deduct a home office after the 2017 tax reform. However, if you have a side business or are self-employed, you can deduct either the actual expenses or use the simplified method ($5 per square foot, up to 300 sq ft / $1,500). The business must use the space regularly and exclusively.

What are the tax advantages of an HSA?

An HSA (Health Savings Account) offers a triple tax advantage: contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. For 2024, you can contribute up to $4,150 (self) or $8,300 (family). After age 65, you can withdraw for any purpose (taxed as ordinary income, similar to a traditional IRA).

Understanding Each Strategy

S-Corp Election

As a sole proprietor, you pay 15.3% self-employment tax on every dollar of profit. An S-Corp lets you pay yourself a "reasonable salary" (subject to FICA) and take the rest as distributions (not subject to FICA). On $100K of business income, this can save $5,000–$10,000+ per year in self-employment tax alone.

SEP IRA

As an S-Corp owner-employee, you can contribute up to 25% of your W-2 salary to a SEP IRA — up to $69,000 for 2024. These contributions reduce your taxable income dollar-for-dollar and grow tax-deferred. Most W-2 employees are limited to $23,000 in 401(k) contributions, so the SEP IRA triples your retirement savings capacity.

Home Office Deduction

If you have a dedicated space used regularly and exclusively for your business, you can deduct it. The simplified method gives you $5 per square foot up to 300 sq ft ($1,500). The actual expense method can yield much more — a percentage of rent/mortgage, utilities, insurance, and repairs. W-2 employees cannot claim this, but side business owners can.

QBI Deduction (Section 199A)

The Qualified Business Income deduction lets eligible business owners deduct up to 20% of qualified business income. For a business earning $80K, that is a $16,000 deduction — worth $3,500–$5,000+ in real tax savings. Phase-out limits apply to specified service trades (law, medicine, consulting) above certain income thresholds.

HSA (Health Savings Account)

The HSA is the only account with a triple tax advantage: contributions are deductible, growth is tax-free, and qualified withdrawals are tax-free. For 2024 you can contribute $4,150 (self) or $8,300 (family), plus $1,000 if you are 55+. After age 65, it functions like a traditional IRA for non-medical withdrawals. The tax savings alone can be $1,500–$3,000+ per year.
