Multi-state payroll tax is a three-part problem
Most tools only solve one or two parts — and the ones that solve all three take a cut of your float. TaxRails handles all three while your money stays in your accounts.
Three steps. Every state. Every quarter.
Multi-state payroll tax compliance isn't one task — it's three distinct operations that each require different tooling, access, and coordination.
Filing Creation
Generate the tax filings themselves — PDFs for record-keeping and the CSV, XML, or flat files that state agencies require for electronic submission.
Portal Submission
Log into each state's tax portal and upload the filing. Every state has its own portal, its own login, and its own quirks — a significant recurring burden at scale.
Tax Payment
Remit the actual tax payment to each state via ACH. This is where the float lives — and where most full-service solutions quietly earn money on your funds.
How the market solves it today
Every existing solution involves a trade-off between automation, control, and who earns the interest on your tax funds.
Payroll Providers
Full-service payroll platforms
Trade-off: They handle everything, but your funds are pre-funded into their accounts — and they keep the interest earned while your money sits there.
Filing Software
Tax filing automation tools
Trade-off: You keep the interest since funds never leave your control — but portal submission and payment remain fully manual across every state.
Managed Filing Services
Full-service tax filing providers
Trade-off: Full service, but they hold your funds and keep the interest. Built on legacy infrastructure that's slow to adapt.
Why Finance Leaders Choose TaxRails
TaxRails handles the full filing, submission, and payment workflow while your money stays in your accounts until the exact moment it needs to move.
End-to-End Automation
TaxRails handles every step of the compliance workflow — generating the required filing formats, submitting to state portals, and initiating ACH payments on the correct due dates. No manual portal logins, no spreadsheet management, no coordination overhead.
- PDF and electronic filing formats for every state
- Automated portal submission across all jurisdictions

Keep the Interest
Traditional managed tax services pre-fund their own accounts — which means your money sits in their system earning interest that belongs to you. TaxRails works directly with your existing bank infrastructure, so funds stay in your accounts until payment is due.
- Funds remain in your accounts until the due date
- No pre-funding into third-party accounts
- No counterparty risk from funds held outside your control
- Works with your existing banking relationships
"With TaxRails, funds stay in their accounts until the exact moment they need to move."
— Josh Cameron, Founder

- Unified payment dashboard tracks all transactions in real-time
- Detailed audit trail documents every step of the process
- Automatic verification with tax agencies confirms proper receipt
- Instant alerts identify potential issues before they become problems
"Before TaxRails, we had no real visibility into where payments stood across all our states. Now we have confirmation at every step."
— Craig C., Director of Finance

Eliminate manual work across every payroll cycle
Each payroll cycle, your team performs tedious manual tax calculations, payment scheduling, and reconciliation work. To do this properly requires daily bank account reconciliation — a time-intensive task someone must perform every single day. TaxRails automates it all:
- Automatic calculation of all tax obligations across jurisdictions
- Optimal payment scheduling to maximize your interest-earning period
- Real-time payment tracking through the ACH network
- Automatic reconciliation eliminates daily manual bank reconciliation

Frequently Asked Questions
TaxRails automates the login and file upload process for each state's tax portal. Rather than your team maintaining credentials and navigating each portal every quarter, TaxRails handles submission end-to-end — generating the required file format for that state and uploading it on your behalf. You get confirmation when each filing is accepted.
No. TaxRails integrates with your existing banking infrastructure via SFTP — the standard method preferred by financial institutions. You keep your current accounts and relationships. Funds stay in your accounts until the exact due date, so there's no pre-funding required.
Most managed tax services require you to pre-fund a pooled account they control — your money moves into their system days or weeks before the actual tax due date, and the interest earned during that period stays with them. TaxRails is different: payments are initiated directly from your bank accounts only when they're due, so the float always works in your favor.
Security is a top priority. TaxRails employs enterprise-grade encryption for all financial data in transit and at rest, implements multi-factor authentication and role-based access controls, and maintains comprehensive audit logs of all system activity. We use secure file transfer protocols (SFTP) to connect with financial institutions — the industry standard preferred by banks for its reliability and security.
TaxRails generates whatever format each state requires — CSV, XML, flat files, and PDFs for record-keeping. Different states have different requirements, and TaxRails handles that complexity automatically based on the jurisdiction.
