The non-resident declaration is far less stressful when the paperwork is already in order. The figures the tax office wants — rents received, the lease terms, the expenses you are deducting — are exactly the documents you generate during normal rental management: leases, monthly rent receipts, and a running record of works and charges.
Keeping these in one place, generated consistently and stored securely, turns the spring declaration into a copy-across exercise rather than a scramble. It also means that if the SIPNR ever asks for proof, you can produce a clean, dated trail in minutes.
The Rent — Lease & Short-Term app and its web companion are built around exactly that: ALUR-compliant leases, monthly quittances, and a year-round record of rents and deductible charges per property that exports a 2044-ready summary when spring comes — ready to copy across or hand to an adviser. They also run a free per-property compliance check — DPE letting-ban status, mandatory diagnostics, SIRET/LMNP, short-term registration and taxe de séjour — at adminlanding.com/french-rental-compliance, no account needed — useful when you manage the property from another country and can't easily keep track of which obligation falls due when. The first property is free, with 10 documents included. It produces the paperwork and the trail; it does not file your return for you.
