Your firm reviews, signs and files every return

Every busy season brings the same squeeze

More returns, fewer experienced preparers, and deadlines that do not move. Your seniors end up keying data instead of reviewing returns, and seasonal hires are slow to find and gone when the season ends.

Anviva takes the preparation load off your senior staff, so they spend the season reviewing, not keying.

How the overnight cycle works

01
Step One

You Send

At close of business, upload source documents or assign returns in your workflow system.

02
Step Two

We Prepare

India is 9.5 to 10.5 hours ahead of US Eastern time, so our workday runs while your office is closed. A preparer builds the return and workpapers, then a second reviewer checks the file and clears e-file diagnostics.

03
Step Three

You Review and File

You open a review-ready return with an open-items list and notes on every assumption. Your reviewer raises notes and we clear them. Your firm signs and files.

Standard returns sent by close of business are ready when your day starts. Complex returns get a committed date at intake.

Four return types, done well

Form 1040

Individual Returns

Form 1040 and schedules, including rental, self-employment and investment income, plus state returns.

Form 1065

Partnership Returns

Form 1065 and K-1s, from trial balance to completed return, with book-to-tax adjustments.

Form 1120-S

S Corporation Returns

Form 1120-S and K-1s, with shareholder basis schedules organized for review.

Form 1120

C Corporation Returns

Form 1120 with Schedule M-1 or M-3 reconciliation and fixed asset schedules.

Also available, scoped on request: trusts and estates, exempt organizations, multi-state returns, extensions and estimates, workpaper preparation and bookkeeping clean-up.

Security built around US rules

Secure Infrastructure

Your Systems, Not Ours

We work inside your hosted tax software or remote desktop. Client files are not downloaded to or stored on our devices.

Access Management

Controlled Access

Unique logins, multi-factor authentication and least-privilege access. Access is removed the same day a team member leaves your account.

Device & Staff Security

Managed People and Devices

Company-managed, encrypted laptops, background-checked staff and signed confidentiality agreements.

Regulatory Support

Built for Your Compliance Duties

We support your IRC Section 7216 consent process and your FTC Safeguards Rule vendor due diligence.

Start small, then scale

Most firms begin with a pilot, move to per-return work, and add a seat once volume is steady. Pricing is fixed and agreed up front.

Questions firms ask first

Your firm does. You review, sign and file every return. We prepare the return and workpapers under your supervision.
We work under your brand and never contact your clients. US rules require you to get client consent before return information is shared with a preparer outside the United States. We provide sample consent wording for your counsel to review and fit our workflow around your consent process.
Standard returns sent by your close of business are ready when your day starts. Complex returns get a committed date at intake.
We correct preparation errors at no charge and log each one so it feeds back into our checklists and training.
Your point of contact is reachable in a daily window from 8 to 11 am Eastern.
Not for per-return work. Dedicated seats have a 3-month minimum. Most firms begin with a 5-return pilot.
