Frequently asked questions
Quick answers about remote tax preparation with Zero Diff Labs.
Are you really 100% remote?
Yes. Zero Diff Labs works with clients entirely online: a short intro video call, secure cloud tools, and an encrypted client portal for documents.
How do I send you documents?
Only through our secure Client Portal, which is by invitation. Please don't email tax documents, and never send them through the website contact form. See how to send us documents.
What does "zero diff" mean?
Every figure on your return should tie back to its source (W-2s, 1099s, K-1s, closing statements, your books) with a difference of $0.00. We don't call a return done until it does. (It's also a nod to git diff, for the engineers: what changed from last year goes into the written analysis delivered with your return.)
What do I get with my return?
A written analysis and recommendations: a short summary of the results, what changed from last year, and recommendations for the year ahead. It's delivered alongside your return for review and e-signature. Questions can go through the portal or by email.
Who do you work with?
Individuals and families, plus real estate businesses: agents and brokers, investors and their LLCs, partnerships, and S corps, developers, and owners of retail and office properties.
Is Zero Diff Labs a licensed public accounting firm?
No. We provide tax preparation and bookkeeping services. We are not a licensed public accounting firm and do not provide audit, review, or other attest services. If a lender or investor requires attest-level financial statements, you'll need a licensed firm for that. See the disclaimer.
Which returns do you prepare?
Individual and business returns: individual (1040, including Schedule C), partnership (1065), and S corp (1120-S).
Can you work from my QuickBooks file?
Yes. As a Silver-tier Intuit ProAdvisor firm, we can work directly from your QuickBooks books. We can also work from year-end reports exported from your property management or accounting software.
How much does it cost?
Each return type has a starting-at price. Your final price depends on complexity and is confirmed in a written quote after a short call. See Pricing.
Do you offer bookkeeping?
Yes, as a secondary service alongside tax prep: monthly bookkeeping and reconciliation in QuickBooks Online (Small Business from $425/mo) and catch-up or cleanup at $200 per month behind. Monthly bookkeeping clients can get 15% off tax preparation. See Bookkeeping.
Which areas do you serve?
We serve clients nationwide, 100% remote.
