What is a startup tax plan?

A startup tax plan is a year-round system that tracks income and expenses, selects the right entity, schedules estimated payments, and maps deductions and credits. The result is lower liabilities and fewer last-minute scrambles. This is the foundation of tax planning for startups.

Choose the right entity from day one

Entity choice shapes rates, payroll, and investor expectations. An LLC taxed as a partnership offers flexibility. S Corporation status can reduce self-employment taxes when wages and distributions are structured correctly. C Corporation treatment may fit venture-backed paths and stock option strategies. Revisit structure at key revenue or funding milestones.

Track everything and keep audit-ready records

Accurate books unlock deductions and clean filings. Separate business banking, automate receipt capture, and reconcile monthly. Consistent categorization prevents leakage on items like software, contractor payments, and travel. Strong records also make credits and grants easier to claim.

Essential deductions to map

• Home office and utilities: Apply the appropriate method and square footage rules.
  
• Equipment and software: Use Section 179 and bonus depreciation where it benefits cash flow.
  
• Health and retirement: HSAs and Solo 401(k) or SEP IRA contributions reduce taxable income.
  
• Professional support: The accountant role in tax planning includes spotting credits, modeling timing, and aligning payroll with equity plans.

Plan quarterly estimates and cash flow

Startups with variable income still need timely estimates. Create a safe-harbor plan, forecast quarterly, and true-up after major contracts or funding events. Schedule payroll tax deposits and sales tax filings on a shared calendar to avoid penalties that drain runway.

Time big moves before year-end

Two levers deliver outsized results: income and expense timing, and the placement of capital purchases. Model AMT exposure and equity events before exercising options or issuing bonuses. Lock retirement contributions and R&D documentation before deadlines.

Use tech that keeps founders out of spreadsheets

Tax rules shift. So does a young company. Run a quarterly check-in to test your entity, revisit estimates, refresh your deduction list, and capture new credits. Add a year-end review to confirm depreciation choices, stock comp, and state filings if operating across borders.
