Find the questions your tax return leaves unanswered.
You filed the return. What does it tell you about the year ahead? X1 reviews the returns you provide and explains questions worth taking to your CPA, with the supporting passages available to check.
Tax return reviews require membership. The calculators linked below can be used separately.

Household update
Considering a change in business structure
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.
Bring the income history and current business plans to your CPA.
Ask which assumptions to model before making a change. This example does not estimate tax savings.

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.
1.
Upload Your Return
Add your 1040, K-1s, and business returns. Choose what to share with your CPA.
2.
We Read the Fine Print
X1 reviews the planning topics supported by your return and keeps each finding connected to the evidence behind it.
3.
Prepare for your CPA meeting
See the questions to discuss first, followed by the full review and the supporting context.
Model a defensible salary range.
An S-corp salary should be defensible for the work performed and the facts of the business. Model a range, document the assumptions, and review it with your CPA.
1.
Plug In Your Numbers
Revenue, expenses, what you're currently paying yourself. Use your current figures.
2.
See What You're Really Paying
The calculator shows the real cost of different salary levels, under the assumptions you enter. It cannot predict audit risk or determine reasonable compensation.
3.
Find the Range That Makes Sense
Not a magic number. A defensible range. Take it to your CPA and have a conversation about the numbers and assumptions.
Model family employment before you act.
Family employment can be appropriate when the work, pay, records, and tax treatment are real. Model the scenario first, then confirm the requirements with your CPA.
1.
Tell Us About Your Kids
Ages, your business structure, and what kind of work they could actually do. Use actual duties and reasonable pay, then verify the treatment with your CPA.
2.
Learn the Rules First
Age limits, reasonable pay rates, documentation requirements, what counts as 'real work.' No shortcuts.
3.
See What It Could Save
Run the numbers on what shifting income to their bracket could mean. Then verify every bit of it with your CPA.
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.
Check the applicable tax year
Keep the review and the tax year together. Ask your CPA to confirm which rules apply before using an estimate for a new year.
Know who does what
Your CPA applies professional judgment to your full situation and handles tax advice and filing. X1 helps you understand the records and questions first.
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?
Keep the tax plan moving
