ADP SmartCompliance Alternative

Full-service payroll tax — without giving up your float.

ADP SmartCompliance handles the work, but it impounds your tax funds into accounts it controls — and keeps the interest they earn. TaxRails handles the full workflow while your money stays in your accounts until the exact moment it's due.

Why Teams Switch

Three reasons companies choose TaxRails over ADP SmartCompliance

Keep your float

ADP pre-funds pooled accounts it controls — your money leaves your books days or weeks before it's due, and the interest stays with them. With TaxRails, funds never leave your accounts until the due date.

API-first, not a bundle

SmartCompliance is built to pull you deeper into the ADP ecosystem. TaxRails is standalone, API-first infrastructure that embeds into the payroll stack you already run — no re-platforming required.

Real visibility, real support

Trade ticket queues and opaque pooled-fund reporting for a unified dashboard that tracks every payment from initiation to agency receipt — and a team that answers.

The Real Cost

The float is not a footnote

Full-service tax providers like ADP require you to pre-fund a pooled account they control. Your money sits in their system between collection and the due date — and the interest earned on it belongs to them, not you.

Your money, their interest

Across dozens of jurisdictions and pay cycles, pre-funded tax dollars add up to a meaningful balance. At today's rates, the interest on that balance is real money — and it's leaving with your provider.

Counterparty risk

When your tax funds sit in a third party's pooled account, you're exposed to their solvency and controls. TaxRails initiates payment from your accounts, so funds you're responsible for never leave your control early.

Works with your bank

TaxRails integrates with your existing banking infrastructure via SFTP — the standard financial institutions prefer. No new accounts, no re-papering relationships, no pre-funding.

Customer Support

When a tax notice arrives, speed matters

State tax notices come with short response windows, and penalties and interest can keep accruing until the issue is resolved. That's why we commit to responding quickly and staying on every issue until it's closed.

48 hrs

A response within 48 business hours

Every support request gets a response from someone who knows payroll tax within 48 business hours. You'll know quickly who is handling your issue and what happens next.

Resolution as fast as we can get it

A response is where we start. We keep working the issue, whether that means a call with the agency, a corrected filing, or a penalty abatement request, until it's closed.

Notices are part of the service

We hold the filing and payment records for every remittance we execute, so we can usually resolve a notice by matching it to data we already have instead of rebuilding months of history.

Common Questions

Switching from ADP SmartCompliance

No. TaxRails is payroll-agnostic, API-first infrastructure. It works with whatever payroll system you run today — there's no requirement to adopt a broader platform or ecosystem.

Instead of pre-funding a pooled account weeks ahead, TaxRails initiates each payment directly from your bank account on the due date. The funds — and any interest they earn while held — stay with you until the moment they must move.

Yes. TaxRails holds the money transmitter licenses required to remit tax funds on behalf of employers, so remittance is executed by a licensed, regulated entity — without you taking on that licensing burden.

You'll hear back within 48 business hours, and we keep working the issue until it's resolved. With notices, speed decides whether a small discrepancy stays small or grows into penalties and interest, so we treat them as a priority.

Keep the service. Keep your float.
