Every Date a Landlord Needs to Track — and When to Act on Each
The dates that actually cost money if missed are: the renewal decision window (start 90 days out), the non-renewal or rent-increase notice deadline (set by your state, often 30–60 days before the term ends), the security deposit return clock (state-set, often 14–30 days after move-out, and strict), insurance renewal, and the January information-return and tax deadlines.
Almost all of them are calculated backwards from a lease end date you already know. That is why they are trackable — and why missing one is avoidable rather than unlucky.
The short version
- Work backwards from the lease end date; every tenancy deadline is derived from it.
- Notice periods are state and city law and they vary a lot — look yours up once, write it into your tracker, and re-check it annually.
- The deposit-return clock is the least forgiving deadline a landlord has; several states impose penalties for missing it regardless of the merits.
- Amber at 30 days, red at 7. A deadline you only see on the day is not tracked.
- January is a deadline month for landlords too: information returns, and closing the previous year's books.
Most expensive landlord mistakes are not decisions. They're dates that passed. The renewal you meant to raise. The notice that needed to go out sixty days before, sent forty. The deposit statement that was due in twenty-one days and went out in thirty.
Every one of these is calculable in advance. Here is the full list, and how far ahead each one needs to be visible.
The dates driven by the lease
| Date | Typical timing | What happens if you miss it |
|---|---|---|
| Renewal decision | 90 days before lease end | You lose the runway to market the unit or negotiate; you renew by default |
| Renewal offer sent | 60–75 days before | Tenant starts looking elsewhere; you find out late |
| Non-renewal notice | State-set, often 30–60 days before | Tenancy may roll on, sometimes month-to-month, sometimes for a full term |
| Rent increase notice | State/city-set, often 30–90 days | Typically the increase cannot take effect until proper notice has run — and in some places the notice must be re-served from scratch |
| Lease end / move-out | The anchor date | Everything else is calculated from it |
| Move-out inspection | Day of or day after; some states require an offer of a pre-move-out inspection | You lose the condition comparison the deposit rests on |
| Deposit return + itemized statement | State-set, often 14–30 days after possession ends | In many states, forfeiture of deductions and statutory penalties |
The dates driven by the calendar
- Insurance renewal. Landlord policy and any umbrella coverage. Set a reminder 45 days out — that's when re-quoting is still possible.
- Property tax installments. Dates set by your county; often two per year.
- Mortgage escrow analysis. Annual; it's what changes your monthly payment without warning.
- Information returns (1099-NEC / 1099-MISC). Recipient and IRS deadlines land at the end of January. See do I have to send my handyman a 1099?
- Tax filing and estimated payments. Your return, plus quarterly estimates if rental income has pushed you into them.
- Annual safety checks. Smoke and CO alarm testing, furnace or HVAC servicing, any local rental registration or inspection scheme — many cities require registration renewal on a fixed cycle.
- Year-end close. Archive the year, start fresh files. Our year-end checklist walks the sequence.
The files that do this for you
The Landlord Ledger Toolkit is 4 Excel/Google Sheets workbooks, 3 editable Word templates and a printable PDF — rent tracking, Schedule E expense logging, maintenance, key dates, move-in/move-out, notices and screening. Built for 2–10 units. One payment, no subscription.
The two-color rule
A date you can see only on the day it falls due is not being tracked; it's being remembered, which is the thing you were trying to stop doing. The rule that works is embarrassingly simple:
- Amber at 30 days — enough time to draft, decide, or get a quote.
- Red at 7 days — enough time to act badly but not to fail entirely.
Implemented in a spreadsheet, that's a column that subtracts today's date from the deadline and a conditional format. Implemented in your head, it's the thing that fails during a busy month — which is precisely the month it matters.
Tracking dates across several leases without software
With four tenancies you have roughly twenty-five live dates. That is genuinely more than memory handles, and genuinely less than justifies $30 a month of property-management software. The middle path is one sheet with one row per obligation: what, which unit, the anchor date it derives from, the notice period, the computed due date, and a status.
The important design choice is that the due dates are computed, not typed. Enter the lease end date and your state's notice period once, and let the sheet work out that non-renewal notice must be served by October 3. Typed dates go stale the moment a lease is extended; computed ones don't.
The one to be most careful with
If you only rigorously track one deadline, make it the deposit return. Many states treat it as close to strict liability: miss the window and you can lose the right to deduct at all, sometimes with statutory damages on top, regardless of how justified the deductions were. It is the only common landlord deadline where being right about the money doesn't save you from being late. Documenting the deduction properly is the other half of that job.

Questions landlords ask about this
How far before a lease ends should I decide on renewal?
About 90 days. That leaves time to decide on terms, make an offer around 60-75 days out, and still market the unit properly if the tenant declines — while staying ahead of most states' non-renewal notice deadlines.
When do I have to tell a tenant I am not renewing?
It is set by state and sometimes city law, and commonly falls between 30 and 60 days before the term ends, with longer periods in some jurisdictions and for longer tenancies. Check your own state's requirement and record it in your tracker rather than relying on a general rule.
What is the deadline to return a security deposit?
State law sets it, and it commonly falls between 14 and 30 days after the tenancy ends. Many states penalize late returns severely, including forfeiting the right to deduct at all, so it is the single deadline most worth tracking precisely.
What landlord tax deadlines exist besides the filing deadline?
Information returns to contractors and the IRS at the end of January, quarterly estimated tax payments if your rental income requires them, property tax installments set by your county, and your year-end bookkeeping close.
How do I track dates across several leases without buying software?
One sheet, one row per obligation, with the due date computed from the lease anchor date and your state's notice period rather than typed in. Add a days-remaining column with amber at 30 days and red at 7.
