Plus 17 federal deadlines: estimated taxes, the annual return matched to your entity, and the employer filings if you hire.
These are the official pages behind the deadlines above. Always confirm a requirement with the agency itself.
Entity type, filing frequency, license dates, whether you have employees or subs. Two minutes, changeable anytime.
Only the South Dakota and federal deadlines that apply to your business, each with the official agency link.
You pick the lead time (default 14 days). The email says what is due, when, and where to file. That is the whole product.
Contractor Lane sends informational reminders with official source links. It is not legal, tax, licensing, insurance, or accounting advice, and it does not file anything for you. You remain responsible for every filing. Deadlines change — confirm with the agency.
