One of the biggest worries I hear from landlords isn’t always about the tax itself.
It’s the records.
Looking back, many landlords have told me they spent months worrying because they couldn’t find everything they thought an Accountant would need.
Some couldn’t find older bank statements.
Others had misplaced tenancy agreements or receipts.
Some weren’t even sure where to begin looking.
Because of that, many delayed asking for professional advice.
By the time we first spoke, they often told me they wished they had contacted me sooner.
Not because they had suddenly found every document.
But because they realised missing records didn’t necessarily mean they couldn’t move forward.
Missing records are more common than you might think
One thing that often surprises people is that very few landlords arrive with years of perfectly organised paperwork.
Life happens.
People move house.
Bank accounts change.
Letting agents come and go.
Documents get misplaced.
When several years have passed, it’s completely understandable that some records may no longer be sitting neatly in a folder.
That doesn’t automatically mean your situation can’t be resolved.
The important thing is understanding what information is already available before worrying about what may be missing.
If you’re unsure what information you should be looking for in the first place, you can read my guide on What Information Should I Gather Before Speaking to an Accountant About Undeclared Rental Income?
Start with what you do know
Rather than focusing immediately on missing paperwork, it often helps to begin with the information you already know.
For example:
- When did you buy the property?
- Did you ever live in it yourself?
- Approximately when did you start renting it out?
- Is the property still rented today?
- Did you manage it yourself or use a letting agent?
Those answers help build the timeline.
Once the timeline is clear, it becomes much easier to identify which records are likely to be useful and where they might still be available.
You may already have more information than you realise
Many landlords initially tell me they don’t have much information.
As we talk through their circumstances, they often realise they already have quite a lot.
Perhaps they still have:
- Some bank statements.
- Mortgage statements.
- Letting agent statements.
- Tenancy agreements.
- Previous Self Assessment Tax Returns.
- Property purchase documents.
Not every document has to cover every year.
Often, those records provide an excellent starting point for understanding the overall picture.
Some records can often be obtained
Another common misconception is that once a document has been misplaced, it’s gone forever.
In many situations, that isn’t the case.
Older bank statements can often be requested from your bank.
Letting agents may still hold copies of statements or rental summaries.
Mortgage lenders may also have historical information available.

Exactly what can be obtained will depend on your own circumstances.
The important thing is not to assume that missing paperwork automatically prevents you from moving forward.

Don’t let missing records stop you asking for help
Looking back, one thing many landlords have told me is that they spent a long time trying to solve the problem on their own before speaking to an Accountant.
They wanted every answer.
Every figure.
Every document.
The interesting thing is that the first conversation isn’t about having everything.
It’s about understanding your circumstances, identifying what information is already available and deciding what the next steps should be.
Once you know where you stand, it becomes much easier to work out how any missing information can be dealt with.

Final Thoughts
If you have undeclared rental income and you’re worried because some of your records are missing, you’re certainly not alone.
Missing paperwork is often one of the biggest concerns landlords have before seeking professional advice.
The important thing is not to let that uncertainty delay the conversation.
Start with what you already know.
Gather whatever information you already have.
Then work with your Accountant to identify what else may be needed.
You may find you already have far more to work with than you first thought.
If you’d like professional advice on your own circumstances, you can book a Paid Tax & Property Consultation.
During the consultation we’ll:
- Understand your circumstances and establish a timeline.
- Discuss what information is already available and what may still need to be gathered.
- Talk through the possible next steps based on your individual situation.
The first conversation doesn’t solve everything.
But it often changes how the journey feels going forward.
