The short answer
- Deadline: the 28th of the month after the stays - or the working day before, if the 28th is a weekend or public holiday.
- Penalty: 20% of that month's tax, added automatically.
- Waivers: none. DoT says the law gives it no discretion.
- What to do: send the complete return now, confirm the amount with DoT, pay tax plus 20%.
How the surcharge works
The surcharge is a flat 20% of the tax due for the late month. It does not depend on how many days late you are: a return that arrives on the 29th attracts the same 20% as one that arrives a week later. The DoT return form has its own surcharge line for this, below the tax total.
Each monthly return stands on its own. If you missed two months, each one carries 20% of its own tax; months filed on time are not affected. The deadline rules are set out in the Tourist Accommodation Tax guide. If a return is many months overdue, ask DoT whether anything beyond the 20% applies to your account rather than assuming.
On a true nil month - no stays at all - 20% of zero is zero. That does not make a missed nil return harmless; see the guide to nil returns for why it still needs filing.
A worked example
A host has four tourist stays that check out in September. The room charges - nights × nightly rate, before cleaning fees and Airbnb's host fee - add up to US$5,200.
| Line | Calculation | Amount |
|---|---|---|
| Room charges (Total Column L) | Sum of September stays | $5,200.00 |
| Tax (Total Column M) | 13% × $5,200.00 | $676.00 |
| Surcharge | 20% × $676.00 | $135.20 |
| Total if late | $676.00 + $135.20 | $811.20 |
Filed and paid by the October deadline, the host pays $676.00. One day late, $811.20. Another way to see it: being late turns the 13% tax into an effective 15.6% of the room charges for that month (13% × 1.2).
If you add the 13% to your guests' prices, the tax itself came from guests - but the surcharge does not. It comes out of your own margin. On a year of returns, a couple of late months can cost more than the time it would take to file them early.
What to do now
- Finish the return today. Use the DoT form, one row per stay that checked out in the month, with the guest folios or receipts as backup. The column-by-column guide walks through each field.
- Fill in the surcharge line. Show 20% of the tax total, and the tax plus surcharge as the amount due. Doing the sum yourself avoids a back-and-forth.
- Email it with the backup to DoT Accounts Receivable at ar@caymanislands.ky. A short covering line - the month, the property, and that you have included the surcharge - helps.
- Confirm before you pay. DoT's guidance is to send the documents first and confirm with Accounts Receivable (345-949-0623) before paying. Ask them to confirm the total including the surcharge, so you do not under-pay and end up with a balance outstanding.
- Pay by local ACH from a Cayman bank, wire, direct deposit or at the DoT cashier, and keep the payment reference with the return.
Waiting does not reduce the surcharge, and it leaves the return outstanding on your account. File the late month before you start on the current one.
Incomplete returns count too
The 20% is not only for returns that arrive late. A return that DoT considers incomplete - the wrong form, missing guest folios or receipts, or missing calculations - and that is not corrected by the 28th is treated the same way. Sending something on the 27th that DoT sends back is not the same as filing on time.
Check these before you send - the first three are what DoT names; the others are easy ways to invite a query:
- Using your own spreadsheet layout instead of the DoT return form.
- Sending the form without the folios or receipts for each stay.
- Room charges that do not match nights × rate, or tax that is not 13% of the room charge.
- Exempt stays with no reason in the Notes column.
- An unsigned form, or one missing the operator name and property details.
If DoT queries your return, answer the same day. Fixing it before the 28th keeps it on time.
Can the surcharge be waived?
No. DoT has said it cannot waive the 20% because the law makes no allowance for it. The only exceptions have been one-off relief granted by Cabinet during COVID in 2020–2021 - not something individual hosts can apply for. DoT also does not accept postal or bank delays as a reason: the deadline is when the return and payment have to reach DoT, not when you sent them.
That last point catches people out. Allow at least one business day for a bank transfer to reach DoT - transfer times vary by bank - so a transfer sent on the 28th can arrive late.
Avoiding it next time
- Work to a file-by date, not the 28th. Aim to file and pay one business day before the deadline. When the 28th falls on a weekend or public holiday, the deadline moves earlier, so your file-by date moves with it. The deadlines calendar lists every date worked out.
- Set reminders well ahead. One at two weeks, one at one week and a final one a couple of days out gives you time to chase a missing folio.
- Start the return early in the month. All the stays for last month have already checked out by the 1st. There is no reason to wait.
- Keep the backup as you go. Download each booking's receipt when the guest checks out, and collect proof for exempt guests before they arrive.
- Know who files. If a property manager handles the listing, agree in writing who sends the return. DoT looks to the licensed operator if it is missed.
- Price the tax in. If the 13% is built into your rates - see charging the tax to guests on Airbnb - the money is already there when the return is due.
Hosts.ky fills in the DoT form from your Airbnb bookings and emails you 14 and 7 days before each deadline, with a last call on the file-by date, and stops the early nudges once you have downloaded that month's return.
