Coastal SC STR Permit and Renewal Tracker: Short-Term Rental Permit, Renewal and Tax Filing Spreadsheet for Charleston Area and Myrtle Beach
A spreadsheet for short-term rental hosts in coastal South Carolina. Pick your area from a dropdown and the permit type, renewal rule, tax stack and official link fill in. Type your expiry dates and it counts down the days, turns red or gold as a renewal gets close, and lists everything due in the next 12 months in date order. Rules data is as of Oct 25, 2026.
What's inside
My Permits: room for 200 permits and licenses. Area, permit type, fees, renewal rule, tax stack and official link fill in from your area pick. Days to renewal turns red at 30 days or less, gold at 31 to 60, green after that.
Tax Filing Log: room for 300 returns. Pick the tax type and how often you file, enter gross receipts and the rate, and it works out the amount due. Status shows Filed, Late, Due this week or Upcoming.
Renewal Calendar: fills in by itself. Your renewals, your unfiled returns and 17 published town and county deadlines (Nov 15, 2026 to May 31, 2027) for the areas you track, sorted by date, with a count per month.
Area Reference: the rules for 12 areas, with permit, fees, caps, owner-occupancy, occupancy, renewal, taxes, recent changes and every official source link.
