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.
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 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.
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.
Keep the service. Keep your float.
