Self‑employed individuals may claim several adjustments to income on Schedule 1 (Form 1040). These adjustments reduce AGI and are available to sole proprietors, independent contractors, partners, and certain S corporation shareholders.

Deductible Part of Self‑Employment Tax

A taxpayer who carries on a trade or business as a sole proprietor or independent contractor is considered self‑employed. Partners also have self‑employment income through their distributive share of partnership earnings.

Self‑employment tax is computed on Schedule SE, and 50% of the self‑employment tax is deductible as an adjustment to income.

  • Deduction is taken on Schedule 1
  • Applies only to the employer‑equivalent portion of SE tax
  • Does not reduce net earnings for SE tax purposes

Self‑Employed Health Insurance Deduction

Taxpayers use Form 7206 to compute the self‑employed health insurance deduction.

They may deduct premiums paid for:

  • Medical insurance
  • Dental insurance
  • Qualified long‑term care insurance (subject to limits)
  • Coverage for spouse, dependents, and children under age 27 (even if not dependents)

Who Qualifies

One of the following must apply:

  • Net profit on Schedule C or Schedule F
  • Partnership income reported on Schedule K‑1, box 14, code A
  • Net earnings computed using optional SE methods
  • More‑than‑2% S corporation shareholder with premiums included in wages

Plan Must Be “Established Under the Business”

Rules differ by entity type:

  • Sole proprietors: policy may be in business or individual name
  • Partners: partnership must pay or reimburse premiums and report them as guaranteed payments
  • S corporation shareholders: corporation must pay or reimburse premiums and include them in Form W‑2, box 1

If reimbursement is not made, the plan is not considered established under the business.

Limitations

  • No deduction for any month the taxpayer is eligible for subsidized employer coverage (their own or spouse’s)
  • Deduction must be subtracted from medical expenses on Schedule A if itemizing

Self‑Employed Retirement Plan Contributions

Self‑employed taxpayers may deduct contributions (other than Roth) to:

  • SEP plans
  • SIMPLE plans
  • Qualified plans (profit‑sharing, money purchase, defined benefit, 401(k))

These deductions are taken on Schedule 1.

SEP Plans

A SEP plan allows contributions to a SEP‑IRA.

Contribution limit for 2025:

  • 25% of net earnings from self‑employment, or
  • $70,000, whichever is less

Contributions must be made in cash.

Defined Contribution Plans

Contribution limit for 2025:

  • 100% of net earnings, or
  • $70,000 (plus catch‑up contributions)

Catch‑Up Contributions (2025)

  • Age 50+: $7,500
  • Age 60–63: $11,250 (SECURE 2.0 “higher catch‑up”)

SIMPLE Plans

Two types:

  • SIMPLE IRA
  • SIMPLE 401(k)

Contribution limit for 2025:

  • $16,500
  • Age 50+ catch‑up: $3,500
  • Age 60–63 “higher catch‑up”: $5,250

Compensation for Self‑Employed Plan Contributions

Self‑employed taxpayers must compute “compensation” using net earnings from self‑employment, reduced by:

  • Employer‑equivalent portion of SE tax (7.65%)
  • Their own retirement plan contribution

Because the deduction and net earnings depend on each other, the contribution rate must be adjusted:

Example (Rewritten)

A taxpayer has:

  • $100,000 net income
  • $7,650 employer‑equivalent SE tax
  • SEP plan rate: 25%

Adjusted rate:

Contribution:

$92,350 * 0.20 = $18,470

Compensation after contribution:

$92,350 – $18,470 = $73,880

Net Earnings From Self‑Employment

Includes:

  • Sole proprietor net income
  • Partner’s distributive share of partnership income
  • Guaranteed payments to partners for services

Does not include:

  • S corporation shareholder distributions
  • Limited partner distributive share (unless for services)
  • Items excluded from gross income (except foreign earned income and foreign housing amounts)
