Payroll tax compliance,
automated across every state.

Warp handles end-to-end payroll tax compliance across all jurisdictions: Federal (income tax withholding, Social Security, Medicare, FUTA), State (income tax, SUI, SDI, workers’ comp, paid family leave across all 50 states), and Local (city, county, and municipal taxes). We also handle year-end filings (W-2s, 1099s, state reconciliation reports) and monitor for regulatory changes.

When you hire an employee in a new state, Warp identifies all required registrations, submits applications to each agency, receives and stores credentials securely in your dashboard, and begins filing and paying taxes on schedule. Most registrations complete within 5-10 business days.

Our AI-powered notice resolution system detects incoming notices, triages by type and severity, researches the cause using payroll data and agency guidelines, and for routine notices (80% of cases) generates and submits responses automatically. Complex issues route to our compliance team with full context.

State tax compliance is included in all Warp plans. No per-state fees, no compliance add-ons. Automatic state registrations, quarterly filings, notice monitoring and resolution, and year-end filings are all included. We pass through government filing fees but never mark them up.

Yes. Our white-glove migration team ports all existing state tax account credentials, verifies account standing, syncs YTD payroll and tax data from your previous provider, and sets up ongoing monitoring from day one. Most migrations complete in 1-2 weeks with zero gaps in filings.

Most payroll providers treat compliance as an afterthought. Manual registrations, reactive notice handling, per-state fees. Warp is AI-native with proactive monitoring, all 50 states included, and full visibility into every registration, filing, and notice in one dashboard.

Payroll tax compliance covers all employer obligations to correctly calculate, withhold, remit, and report payroll taxes at the federal, state, and local level. This includes federal income tax withholding, Social Security and Medicare (FICA), federal and state unemployment insurance, and any applicable local taxes, plus recurring filings like Form 941 and year-end W-2s. Non-compliance carries steep penalties: the IRS charges up to 15% of unpaid taxes for late deposits alone, and state agencies add their own fines on top. Warp automates every filing and registration across 10,000+ jurisdictions, so you stay compliant without ever visiting a .gov site.

When a company employs people across multiple states, it must register with and remit payroll taxes in each state where employees work, not just where the company is incorporated. Requirements vary widely and include state income tax withholding accounts, state unemployment insurance (SUI) accounts, local jurisdiction taxes, and state-specific obligations like disability insurance in California and New York. Most states require separate registrations for withholding and unemployment, with different deadlines across all of them. Warp's AI agents open every required state account automatically when you add a new employee location and file every required form on time.

Staying compliant requires managing state registration deadlines, quarterly and annual filing schedules, and tax notices from agencies across every jurisdiction where you have employees. For most growing companies, the most reliable approach is a payroll platform that automates these obligations end to end. Warp handles state registrations, quarterly filings, W-2s, 1099s, and tax notice resolution automatically across 10,000+ jurisdictions. Every account also includes a dedicated Account Manager to guide you through multi-state expansion, so compliance never slows your hiring.
