Tax returns, interpreted year over year.

Your tax return is the largest financial document your household produces each year. Tax Optimization reads last year's return against this year's structure, remembers what you decided last time, and packages the questions worth asking before your next CPA meeting.

Explore with a free account. Some planning and review tools require membership.

Tax review

Avery household

What changed since the last return?

Two years of income. A new question about business structure.

The 2024 and 2025 returns provide the income history. The household’s new update adds a separate question: should the business structure change? The returns alone cannot answer that.

Illustrative example. Fictional household.

Read the return before the next CPA meeting.

Upload last year's return and we'll read it for you. Not to file it. We look for the things worth asking your CPA about, retain every material finding in the complete review, and put the clearest priorities first.

  • Are there additional deductions?

Your structure changes between annual CPA meetings.

Your ownership, income, and family circumstances can change between annual meetings. A current, cited question helps your CPA focus on the decision that needs professional judgment.

Keep the Complete Review

Start with the priorities, then explore the full review and its supporting evidence.

Know the Risks

Every strategy has trade-offs. We show you the compliance considerations so you go in with eyes open.

Do the Math First

Run the numbers before the meeting. Know what's at stake. Come with scenarios, not just questions.

Share With Your CPA

Export your analysis and share it. Good CPAs love prepared clients. It makes their job easier.

Stay Current

Tax law moves every year. What worked last cycle might not work now. The tools stay current and your decision memory carries forward.

Complement, Don't Replace

We're not trying to fire your CPA. We're trying to make your CPA meetings worth the money.

Make the CPA meeting productive

A clear definition and a short checklist keep the conversation focused on decisions, not theory.

What tax optimization means here

Tax optimization in X1 means turning your real tax data into a set of questions, scenarios, and handoffs for your CPA. It is a planning workflow, not filing or advice.

Before your next conversation

  • Do you have last year's returns and K-1s ready to review?
  • Has income, ownership, or entity structure changed since last year?
  • Are you making decisions without running a scenario first?
  • Do you know which strategies are legal but not appropriate for you?
  • Can you summarize the decision in one paragraph for your CPA?
Questions to bring to your professional
  • Which two strategies are most worth modeling this quarter?
  • What would materially change my effective tax rate this year?
  • What documentation would you want before we adjust the salary split?
