Short answer. Yes, and you should. The rule requires claims for money arising from contract to be filed whether they are due, not due, or contingent, and it provides that claims not yet due or contingent may be approved at their present value.

Waiting for maturity is the mistake
The instinct is to wait: the loan is not payable until next year, so there is nothing to demand yet. That instinct is wrong here, and expensively so. The rule sweeps in claims whether the same be due, not due, or contingent, and puts them all under the same filing period. A creditor who holds off until the debt matures may find the period in the notice has closed in the meantime, and the rule's consequence for that is that the claim is barred forever.
Contingent claims count too
The rule reaches beyond debts that are certain but not yet payable. A contingent claim — one that depends on something that may or may not happen, such as liability under a guarantee that has not yet been called on — is expressly included. This is worth noticing if you are unsure whether you are a creditor at all. Uncertainty about whether the estate will ever owe you is not a reason to stay out; on the rule's wording it is one of the situations the filing requirement was written to cover.
How an immature claim is valued
Filing early raises an obvious problem: how can an estate be closed while owing money that is not yet payable? The rule answers it directly by providing that claims not yet due or contingent may be approved at their present value. Rather than holding the estate open until maturity, the claim is brought forward and valued as at the present. So the effect of filing is not that you are paid the face amount today; it is that the claim is recognised and quantified rather than lost.
What to prepare
Because valuation is part of the process, the documents that establish the terms — the amount, the maturity date, the interest, and any condition the obligation depends on — do more work than a bare demand letter would. The source of the obligation matters too: the rule frames this category around claims arising from contract, express or implied. If you are unsure whether your claim fits, or how to put a present value on it, take the underlying documents to a lawyer well before the period in the notice expires.
