Self-Employment Tax Tips

How SE Tax Works

Self-employment tax covers both the employer and employee portions of Social Security (12.4%) and Medicare (2.9%) taxes, totaling 15.3%.

92.35% Rule

SE tax is calculated on 92.35% of net self-employment income, which accounts for the employer-equivalent portion.

Deductible Portion

You can deduct 50% of your SE tax when calculating your adjusted gross income, reducing your income tax burden.

Quarterly Payments

If you expect to owe $1,000+ in taxes, make quarterly estimated payments to avoid penalties. Due dates: Apr 15, Jun 15, Sep 15, Jan 15.
