K-1 Tax Planning for Partnerships and LLC Owners

Updated September 10, 2026 · 6 min read · Montreux Wealth Management

In brief

K-1 tax planning for partnership and LLC owners means projecting pass-through income early, coordinating estimated tax payments, aligning retirement plan contributions with entity profits, and ensuring investment portfolio decisions account for irregular K-1 timing and character of income.

Why K-1s complicate planning

Schedule K-1 income may include ordinary business income, capital gains, dividends, and Section 179 deductions - often arriving late in tax season. Without projections, owners underpay estimated taxes or miss deduction timing opportunities.

Integrated strategies

Cash Balance Plans, pension contributions, and entity-level retirement structures should be modeled against projected K-1 income before year-end. Investment portfolios should maintain liquidity for tax payments without forced sales at unfavorable times.

Montreux provides K-1 preparation and coordinates planning with your broader wealth strategy.
