The scene
The scene
Maria has worked from home three days a week for the past four years. Her electricity bill went up. She bought a desk and a chair. She uses her internet for work. She subscribes to two software tools she only uses for her job. She replaced her laptop last year because the old one could not handle a video conferencing setup.
She has never tracked any of it.
Each year, when tax time approaches, she opens her bank statements with the vague intention of pulling together the work-related expenses. The statements show twelve months of mixed personal and work charges. She cannot remember which laptop accessories were for work and which were for her kids' homework. She does not have the electricity bill broken down by working hours. She cannot find the receipt for the desk. The chair she bought on a card she no longer uses.
By the deadline, she gives up. She claims the standard work-from-home rate her tax agent suggests, which is something but probably less than what she could have claimed with proper records.
Across four years, the deductions she did not claim add up to several thousand dollars. Not because the expenses were not there. They were. Because she never tracked them in the moment, and reconstructing them after the year is over is too hard to do well.
Her colleague Elena has done it differently. Elena set up a separate folder in her email called "Tax expenses". Every time a work-related receipt arrives, she forwards it to that folder. Once a quarter she spends 15 minutes adding new expenses to a simple spreadsheet. At tax time, the spreadsheet is the deduction. No reconstruction needed.
Elena and Maria earn similar salaries. They have similar work-from-home setups. Elena claims meaningfully more in deductions each year. The difference is not knowledge. It is one folder and 15 minutes a quarter.
What your brain just did
What your brain just did
Our minds prefer doing a small task later to doing it now, even when doing it now costs almost nothing. Maria is not disorganised. Her brain treats each individual receipt as too small to bother with, the way all our brains do when an action is tiny and the consequences are distant. This behaviour has a name: Present Bias.
What to do instead, in one move
What to do instead, in one move
The fix is one folder and one reminder. Create an email folder labelled "Tax expenses". Set a quarterly calendar reminder to spend 15 minutes adding new receipts to a spreadsheet. The 15 minutes a quarter is the difference between reconstructing nothing at tax time and claiming what you legitimately spent.
TL;DR
- Situation: You incur work-related expenses through the year. You do not track them as they happen. At tax time, you cannot reconstruct them and you under-claim.
- What your mind does: It treats each individual tracking action as too small to bother with now, while the cumulative cost of not tracking is invisible until tax return time (this is called Present Bias, see below).
- Consequence: Years of legitimate deductions are not claimed, not because the expenses were not real, but because the records to substantiate them were never kept.
- What to do: One email folder, one quarterly 15-minute reminder. The system that makes tracking automatic outperforms any intention to "track better next year".
What to do
- Create an email folder labelled "Tax expenses". Every time a work-related receipt arrives by email, move it to that folder. The action takes three seconds.
- Set a recurring quarterly calendar reminder labelled "Add tax expenses to spreadsheet". Spend 15 minutes adding the quarter's receipts to a simple spreadsheet with date, vendor, amount, category.
- For physical receipts, photograph them with your phone and email them to yourself with "tax" in the subject. The photo plus email gets them into the same folder as the digital ones.
- For work-from-home specific expenses, keep a separate note of the dates you actually worked from home. Some calculation methods require this and reconstructing it after the year is much harder than tracking it weekly.
What not to do
- Do not plan to "track better next year" without changing the structure. The system, not the intention, is what produces the records.
- Do not skip small expenses because they feel too small. A $40 subscription times twelve months is $480 in expenses, which at a moderate marginal rate is over $150 in deductions. That is real money.
- Do not assume your tax agent can reconstruct the year for you. They work with what you give them. What you give them is what you tracked.
Tracking expenses is not the boring part of the deduction. It is the deduction.
Want to understand why this happens?
Present Bias is the brain's tendency to overweight immediate small costs and underweight delayed larger benefits.
For tracking expenses, the bias produces a specific pattern. Each individual act of tracking (moving an email, photographing a receipt, jotting down a date) takes seconds. The benefit (a deduction at tax time) arrives months later. The brain compares "do something tiny now" against "abstract benefit in the future" and consistently picks doing nothing now.
The bias is not laziness. The tracking actions really are tiny in isolation. The issue is that the brain cannot accurately model the cumulative benefit of doing the tiny action consistently over twelve months. So each individual instance gets skipped, and the cumulative outcome is the loss of records the brain never decided to lose.
It is not you. It is how every human brain handles small recurring tasks with delayed payoff.
What the research found
O'Donoghue and Rabin's 1999 research on Present Bias documented that people consistently postpone small actions with delayed rewards, even when the action would clearly serve them. The pattern is so robust that it explains a wide range of behaviours, from gym attendance to retirement contributions to expense tracking.
For tax records specifically, surveys conducted by tax agencies across multiple jurisdictions have repeatedly found that workers who could legitimately claim deductions often do not, primarily because they did not keep adequate records during the year. The deductions are not denied. They are not claimed.
The fix is to remove the moment of decision. By setting up a folder and a quarterly reminder, the tracking happens almost automatically. The brain does not have to decide each time. The system has already decided.
"We consistently prefer doing nothing now to doing something small now, even when the something small adds up to something large later." O'Donoghue and Rabin (paraphrased from Doing It Now or Later, 1999)
