Catching Up After a Move or a Busy Season
Overdue filings in Spearfish tend to follow one of a few patterns. Someone relocates to the Black Hills and forgets the final return owed to the state they left. A homeowner lists a spare room or cabin for the rally and never registers to collect tax. A builder takes on more projects than the office can handle, and excise tax returns and the city licence renewal slide. A summer business shuts for the winter and nobody files the quiet-season returns. BOMCAS reconstructs the missing years and prepares the overdue filings for Spearfish clients remotely. Our role is preparing returns and schedules; we do not act as anyone's representative before the IRS, and if you need one we will coordinate with the person you appoint.
State penalties and voluntary disclosure are explained on our South Dakota late filing page. The cases below are the ones we see most in Spearfish.
Our Order of Work
- Pull IRS wage and income transcripts to see what was reported in your name.
- Look up the South Dakota sales tax and reemployment assistance accounts for open periods.
- Collect booking platform statements, deposits, invoices and pay records.
- Rebuild the income and expenses for each year.
- Prepare the returns and a summary of tax, penalties and interest.
- Agree a calendar so the same gaps do not reopen.
The State You Left
Leaving a state does not end its claim on the income you earned there. A part-year return is normally due for the year of the move, and nonresident returns may follow if you kept a rental, sold property or did work there afterwards. Some states compare federal data years later and send estimated assessments. We prepare the outstanding returns using the move date and the income that belongs to each period.
Unfiled Federal Years
Six years is the period the IRS normally looks for before it treats someone as compliant again. If the IRS has already prepared a return for you from wage and 1099 reports, it will not include your expenses or credits, and an original return usually brings the bill down. Penalty relief may be available for a first offence or for a documented hardship, and once filing is complete, monthly installment arrangements are common.
Short-Term Rentals
Hosts who took direct bookings, through a personal website, repeat guests or local listings, without collecting tax should get a South Dakota sales tax licence and report the past stays. If you approach the Department of Revenue before it contacts you, its voluntary disclosure process can shorten the period you must report and may reduce penalties. Platform bookings on which the marketplace collected tax are generally excluded, so we separate them first.
Builders and Trades
A contractor who did not file contractor's excise tax returns can rebuild receipts from contracts, draw requests and deposits. Renew or obtain the Spearfish contractor's licence before taking new jobs inside the city or the joint powers area. Work done in Wyoming without registering may have left Wyoming sales and use tax, unemployment insurance or workers' compensation balances that should be settled at the same time.
Withholding That Was Not Deposited
When an employer keeps employees' withheld tax instead of depositing it, the IRS can collect that amount personally from the owners or managers who controlled the payments. We match pay records to deposits, prepare the missing quarterly and annual forms and set a deposit routine that fits the business's cash flow.
Hotels Behind on the District Charge
The $2 room charge is reported to the city on its own monthly form. A hotel that missed months should total the room nights for each period from its property management system and bring the account current with the city finance office.
Letters With Deadlines
Proposed adjustments, requests for a missing return and state assessments all have response dates. Send us the letter as soon as it arrives, and we will gather the records and prepare the figures or returns needed.
After the Backlog
Monthly books, scheduled payroll and a filing calendar that includes the 2027 rate changes keep the account clean.
Spearfish Back Taxes and Late Filing Questions
I moved here two years ago and never filed in my old state. What now?
File the part-year return for the year of the move and any nonresident returns for income earned there afterwards.
I rented my house during the rally without a licence. What should I do?
Register for a sales tax licence and file past periods. Voluntary disclosure may limit penalties if you come forward first.
How many years of federal returns should I file?
The IRS usually expects the last six years, but your case may differ.
Will you contact the IRS for me?
No. We prepare returns and schedules only. If you need someone to speak for you, we will coordinate with the representative you appoint.
