Your declaration is an annual job, not an annual form

Both numbers set your premium. Most businesses treat the second one as a payroll report and the first one as a guess, and both of those habits cost money.

What the two declarations are

Since 1 July 2024 they are approved forms under the Act.

IN1, Declaration of Estimated Remuneration. Lodged when a policy starts or renews. It is what your premium is charged on for the year ahead.

IN2, Declaration of Actual Remuneration. Lodged at the end of the period. It is what your premium should have been, and the difference between the two is adjusted.

Every insurer publishes the identical forms, because an insurer cannot alter an approved form.

The estimate is not a formality

An estimate set low does not save you money. It defers it.

The gap between what you estimated and what you actually paid is adjusted at the end of the period, and the adjustment lands on you in one bill you did not plan for. What a low estimate buys is a cash flow problem twelve months out.

The reverse is also true and it is the one nobody notices. An estimate set high means you have been paying premium all year on wages you never paid. You get it back at adjustment, but you have funded your insurer's float in the meantime.

A genuine best estimate is the cheapest of the three.

The actual is where the errors are

Because it is usually built from a payroll report, and remuneration is a longer list than payroll.

Allowances. The grossed up taxable value of fringe benefits. Salary sacrificed superannuation, which payroll shows as a reduced gross. The labour component of payments to contractors who meet the definition of a worker. Accrued leave paid out on a termination, which usually gets excluded along with the termination payment it was paid beside.

And the reverse, which costs you the other way. Payroll tax, redundancy payments, payments in lieu of notice and compulsory superannuation are not remuneration, and they get declared more often than you would think, usually because somebody read a figure off a ledger account. What counts as remuneration

What changes between one year and the next

The declaration is annual because the answers move. Five things move quietly and nothing in the ordinary process re-tests any of them.

Your classification. It is set by your predominant business activity measured in wages, so a second activity growing from 30% of payroll to 55% changes the answer without anyone filing a thing. Is your classification right?

Your host mix, if you place workers. A labour hire firm placing into one industry at inception and three by year end has a different declaration than the one it lodged.

Your directors. Cover is optional in Western Australia and exists only where each director is named on the policy and their remuneration is declared at the time. A director who started working in the business this year is not covered by last year's arrangement.

Your contractors. Arrangements change, and whether someone meets the definition of a worker turns on the working arrangement rather than the invoice.

The rate schedule. WorkCover WA fixes recommended rates once a year on six years of claim experience for your whole industry. Your rate can move with nothing in your business changing. Why your premium changed

The dates, because they set your runway

Your insurer has obligations on timing and most employers never look at them.

For a renewal, the insurer invites renewal in writing at least 30 days before expiry, and provides full terms within 14 days of receiving the information they need, and before the policy expires.

For a new policy, a written quote with full terms within 14 days of the request.

And if either side intends to change the industry classification on a current policy, the other must be told at least one month before expiry.

That last one matters. A classification change arriving with the renewal notice is late, and the window to do anything about it is short. If the terms look wrong, the application to WorkCover WA has to be made within one month of the date you received the quote.

What we do

The same job, once a year, before the declaration is lodged rather than after.

We build or check the estimate from your actual rates, roster, allowances and superannuation treatment. We reconcile the actual figure against the payroll, the BAS or IAS, the general ledger wages accounts, superannuation and the FBT position, so the number you lodge has its working attached. We test the classification against the coding rules rather than assuming last year's answer still holds. And we tell you what changed and why.

Where a contractor or a working director needs a judgement rather than an arithmetic answer, you get the judgement and the provision it rests on.

The second year costs less than the first. Most of the work in year one is establishing positions that then hold: your classification, which contractors are workers, how each director is paid, and where the figures come from in your own system. After that it is maintenance.

What we do not do. We do not deal with your insurer, your broker or WorkCover WA on your behalf, and we do not lodge anything for you. We are not insurance brokers and we do not advise on which insurer or policy to choose.

Fees are fixed, agreed in writing before any work starts, and never a percentage of anything.
