how do I fill in the sales forecast for my insurer

A revenue forecast is an estimate, not annual accounts

Enter here the amount that the enterprise itself expects for the coming year, with a brief explanation of the assumptions behind it — for example order portfolio, seasonal pattern or an ongoing contract that is ending or being added. There is no statutory prescribed format for this forecast: it is not data that comes from the Trade Register like statutory business data, and neither is it annual accounts that are publicly deposited. It is the enterprise's own statement, and the insurer uses it to assess the risk for the coming year — often together with a question about creditworthiness, where you can find more about this here.

If you do not have an internal forecast model, a substantiated estimate based on the latest turnover figures plus an expected growth or decline percentage is common practice. Some portals ask for a range instead of a fixed figure; then enter the range that best matches what has already been discussed internally, for example in a budget or management report. Note: this is different data from the question about deposited annual figures — see here the difference with the question of whether the annual accounts are deposited — a forecast looks ahead, annual accounts look back and are moreover an established, audited figure.

Why insurers ask for future figures

A revenue forecast is not laid down in a specific law that obliges insurers to request it; it is part of the insurer's own risk acceptance, comparable to the way banks conduct customer due diligence on the basis of Directive (EU) 2015/849 to prevent money laundering and terrorist financing, but aimed at assessing premium and cover instead of integrity risks. However, the question can be related to broader reporting obligations that work through the supply chain, such as sustainability reporting under Directive (EU) 2022/2464, in which forward-looking information — estimates of future performance — also plays a role for larger enterprises in the chain.
