Quarterly filings

Quarterly payroll filings, without the calendar anxiety.

If you have employees, you've got at least four recurring filings every quarter — federal 941, Minnesota withholding, Minnesota unemployment, and the year-end 940. Miss one and the penalty letters start. We file every cycle, on time, and reconcile to your books at year-end.

The quarterly rhythm

The same four dates, every year.

The filings cluster at the end of the month after each quarter — with January 31 carrying the year-end load on top.

What this covers

The payroll filings that don't run themselves.

Most payroll providers (Gusto, ADP, Paychex) handle the actual quarterly filings — but they only do it if their data is correct, the payments are funded on time, and someone is watching for state-side discrepancies. We act as the second pair of eyes: confirming filings went out, reconciling deposits to liability, responding to state notices, and filing the returns directly when you don't use a payroll service. For employers running payroll in-house or with smaller payroll providers, we handle every quarterly cycle end-to-end.

What we handle

The quarterly + annual filings, by name.

These are the recurring filings that touch every Minnesota employer with W-2 staff.

Federal Form 941

Quarterly

Federal employment tax return — wages, federal income tax withheld, Social Security and Medicare. Due Apr 30 · Jul 31 · Oct 31 · Jan 31.

Minnesota withholding

Quarterly

State income tax withholding reconciliation, filed through the Minnesota Department of Revenue's e-Services portal.

Minnesota unemployment (UI)

Quarterly

Wage report and tax payment to the MN Unemployment Insurance program. Due the last day of the month after each quarter.

Federal Form 940

Annual

Federal unemployment (FUTA) return, filed by January 31. The liability accrues quarterly and is deposited whenever it exceeds $500.

W-2 + W-3 + 1099-NEC

Year-end

W-2s to employees, 1099-NECs to contractors paid $2,000+ (2026), plus the W-3 and 1096 transmittals — all due January 31.

Notice + reconciliation

As needed

When the state flags a discrepancy between filings and deposits, we find the cause and respond. Most are bookkeeping mismatches, not real problems.

The blind spot

Payroll providers aren’t auditors of their own work.

They handle the mechanics well — but they only see the data you give them. These are the things that slip through, quietly, until a year-end notice or a state audit surfaces them:

  • A contractor misclassified as an employee (or the reverse)
  • A state rate that changed without your payroll setup updating
  • A deposit timing missed over a long holiday weekend
  • Filings that went out but don't match your books
  • A 1099-NEC contractor who never got set up to receive one
  • A state notice that landed in an inbox no one checks

We sit between your bookkeeping and your payroll provider, reconcile every quarter, and catch the small mismatches before they compound.

Common questions

What people ask us about this.

Four filings, four deadlines, four quarters.

Quarterly filings are predictable — until one slips and you spend three weeks responding to notices. We keep the cadence steady.
