S-Corp Basis & Reasonable Compensation Guide

How to track S-corp shareholder basis, calculate reasonable compensation, and document distributions without triggering audit flags.

5 stepsentity
1

Establish initial basis

Start with the shareholder's capital account balance at the beginning of the tax year. Include stock basis (original investment + capital contributions) and debt basis (loans from shareholder to the S-corp).

2

Track income and loss items

Increase basis by ordinary income, tax-exempt income, and excess depletion. Decrease basis by ordinary losses, nondeductible expenses, and distributions. Order matters — losses are limited to basis.

3

Calculate reasonable compensation

Determine what the S-corp officer/owner would earn for similar work in a comparable position. Factors: duties, time spent, skill level, local wages, and distributions vs. salary ratio.

4

Document the analysis

Record the reasonable compensation analysis each year. Include comparable salary data, the shareholder's role and hours, and the reasoning for the chosen amount.

5

Reconcile distributions

Compare total distributions to accumulated basis. Distributions in excess of basis trigger capital gains. Document the distribution policy and its relationship to compensation.
