For Accounting Firms & CPAs

Give every client a portal that answers "where did this number come from?"

Stop fielding post-season calls. BasilTax creates a white-labeled verification portal for every client — tracing each line on their return to the exact source document. They self-serve answers. You retain clients and bill for the value.

The hidden cost of every tax season

You prepare excellent returns. But clients still don't understand what they signed — and that creates ongoing cost for your firm.

40%

of post-season calls

are clients asking "what does this number mean?" — questions a self-service portal eliminates entirely.

$200/hr

audit reconstruction

When the IRS sends a notice, you reconstruct what happened from scratch — billable but unpopular, and often written off.

15%

annual client churn

Clients leave when they feel uninformed. Transparency builds trust. Trust builds retention year over year.

How BasilTax works for your firm

Set up once. Every client gets their own verification portal automatically.

1

Upload client documents

Upload the same W-2s, 1099s, and statements you used to prepare the return. Or invite the client to upload directly into their portal.

2

Audit trail is generated instantly

Every number on the return is traced to a specific document, page, and field. No manual annotation required.

3

Share the portal with your client

Send a branded link. Clients see your firm's name and logo. They can explore their return, ask questions, and download audit-ready PDFs.

4

Clients self-serve — you focus on advisory

When clients have questions, they ask the portal. Answers come with document citations. You stop being a call center and start being a strategic advisor.

Client portal preview

Your client asks:

"Why do I owe $12,400 this year?"

Portal answer:

Your tax liability increased because you had $48,000 in additional capital gains this year (1099-B, Fidelity, pages 2–8) with no corresponding withholding. Your W-2 withholding covered your salary but not the investment income. See 1040 Line 24 vs Line 25d.

Turn transparency into revenue

Most firms offer this as a premium add-on. Clients gladly pay for peace of mind.

Frequently asked questions

How does BasilTax work for accounting firms?

You upload client documents (or invite clients to upload directly). BasilTax creates an audit trail tracing every number on the return to its source document with page references. Clients access their own branded portal to view the trail and ask questions — reducing your support burden.

Can I white-label the client portal with my firm's branding?

Yes. On Professional plans you add your logo and firm name. On Firm plans you get full white-labeling including a custom domain (e.g., verify.yourfirm.com) so clients never see BasilTax branding.

How do accounting firms monetize BasilTax?

Most firms offer audit-ready verification as a $50–$150 premium add-on per client. With 60%+ uptake typical in year one, the subscription pays for itself many times over while increasing client retention and satisfaction.

Is client data secure?

All SSNs and PII are redacted before AI processing. Data is encrypted at rest and in transit, never sold or shared, and never used for model training. Each client's data is isolated to their account.

What if my client gets an IRS notice?

Clients can pull up their BasilTax audit trail, find the exact source document and page number for any questioned amount, and respond to the IRS with confidence — often without needing to schedule a meeting with you.
