關於此工具
請輸入您的自僱淨利潤 (或S公司, W-2工資),年齡和年份.計算機將您的自雇稅款中一半扣除,應用員工延期限制,僱主20% (或25%) 的股份和追趕金額,並與SEP IRA比較總額.
單人經營者或 LLC
Your plan earnings are net profit minus half of self-employment tax. The employer share is 20% of those earnings (the 25% rate, applied after the contribution itself is deducted). You can also defer up to $24,500 in 2026 ($23,500 in 2025) as an employee, up to your earnings.
公司
The employer share is 25% of your W-2 wages, and you defer from your wages. The compensation counted is capped at $360,000 in 2026 ($350,000 in 2025).
總限數
Deferral plus employer money cannot exceed $72,000 in 2026 ($70,000 in 2025). Catch-up contributions are on top: $8,000 at 50 and over, $11,250 at ages 60 to 63 in 2026. A SEP IRA allows only the employer share, so a solo 401(k) usually lets you save more at modest incomes.
計算示例
A sole proprietor aged 45 with $100,000 of profit in 2026: half of self-employment tax is $7,065, plan earnings are $92,935, the employer share is $18,587 and you can add $24,500 of your own deferrals, for $43,087 in total. A SEP IRA would allow $18,587.

常見問題
Which profit do I enter?
Net profit from Schedule C (or your share of partnership income), before the deduction for half of self-employment tax.
雇主為何有20%的份額而不是25%?
For the self-employed the 25% rate applies after the plan contribution is deducted, which works out to 20% of net earnings.
