I checked my bank account last Tuesday.
Not in the calm, responsible, I'm-on-top-of-my-finances way. In the 3am, one-eye-open, stomach-already-sinking way. The way where you know it's going to be bad but you look anyway because the not-knowing has become worse than the knowing.
There was a gym membership I forgot to cancel. Again. A subscription box I don't remember signing up for. Two late fees on bills I genuinely meant to pay on time. And about £47 worth of Amazon purchases that I couldn't identify but apparently seemed absolutely essential at 11pm on a Wednesday.
Sound familiar?
This is the ADHD tax. And if you've got ADHD, you're probably already nodding.
What the ADHD tax actually is
The ADHD tax isn't a real tax. It's the term the community uses for the hidden financial cost of living with a brain that processes time, urgency, and reward differently to everyone else's. It's the cumulative price you pay for executive dysfunction showing up in your bank account.
Late fees on bills you had the money for but didn't pay on time. Duplicate purchases because you forgot you already owned one. Impulse buys that felt life-changing at 11pm and meaningless by morning. Subscriptions bleeding quietly out of your account because cancelling requires three steps and your brain can't do three steps right now.
Research covered by UK financial platforms suggests adults with ADHD can end up paying upwards of £1,600 extra per year in avoidable costs. Late payment fees, impulse spending, forgotten direct debits, replacing things you've lost. According to ADHD UK, nearly half of adults with ADHD report regularly missing bill payments, compared to around 18% of the general population.
Sixteen hundred quid. Every year. Not because you're careless. Not because you don't care. Because your executive function has a different relationship with "later" than everyone else's does.
Why your brain keeps buying things you don't need
Here's the bit that actually made me stop beating myself up about the Amazon orders.
ADHD brains are chronically low on dopamine. That's not a metaphor. It's neurochemistry. Your prefrontal cortex, the part responsible for planning, impulse control, and reward evaluation, is running on less fuel than a neurotypical brain. So it goes looking for dopamine wherever it can find it.
And you know what gives you a beautiful, instant, no-effort dopamine hit?
Buying something.
Not owning it. Not using it. Buying it. The click. The confirmation email. The little rush of "this will change everything." That's the reward. The item itself is almost irrelevant. That's why you've got fourteen half-used journals, a spiralizer still in the box, and a drawer full of hobby supplies for hobbies you tried once.
Your brain isn't being stupid. It's being resourceful. It found a dopamine source and it keeps going back to it. The problem isn't your character. It's that the quick fix comes with a price tag.
And here's the kicker. The guilt you feel afterward? That also depletes dopamine. So you feel bad, which makes your brain crave another hit, which means another purchase, which means more guilt...
Every. Single. Time.
The shame spiral nobody talks about
This is the bit I really want to go deep on. Because the money itself is only half of it. The other half is what the money does to your sense of self.
It goes like this.
You miss a payment. Not on purpose. You meant to do it. You thought about doing it. You even opened the app and then got distracted and the payment just... didn't happen. So there's a late fee. And now you feel guilty. And the guilt makes you not want to look at your bank account. So you don't. And while you're not looking, another payment gets missed. And another fee lands. And the number gets worse. And the shame gets louder. And the avoidance gets stronger.
This isn't laziness. This is emotional dysregulation applied to your finances.
The NHS lists difficulties with emotional regulation as a core feature of ADHD in adults. Not an add-on. Not a personality quirk. A core feature. As of 2026, this is increasingly well understood by clinicians, but the average financial advice still assumes you can "just check your statements regularly" and "just set a budget." As if the "just" isn't the entire problem.
And the letters. God, the letters.
The brown envelopes you don't open. The emails you archive without reading. The voicemails you delete without listening to. Not because you don't care. Because your nervous system has decided that the information inside them is a threat, and the only available response is to look away.
I know people who've had bailiff letters sitting unopened on their kitchen counter for months. Not because they're irresponsible. Because their brain classified "opening this envelope" as emotionally equivalent to walking into traffic. The fear response is that real. That physical. That wildly disproportionate to what's actually inside the envelope.
And then someone says "well, you should have opened it sooner" and you want to scream into the sun.
The system was not designed for your brain
Let's zoom out for a second. Because I think there's something bigger happening here that doesn't get said enough.
The entire financial system assumes consistent executive function.
It assumes you can remember when things are due. It assumes you'll check your statements. It assumes you'll cancel things you don't need. It assumes you'll compare deals, switch providers, read the fine print. It assumes, fundamentally, that you are paying steady, reliable attention to your money at all times.
And if your brain doesn't do steady and reliable? You get punished for it. Financially. Over and over and over.
The budgeting advice doesn't help either. "Track your spending." Mate, I can't track what day it is. "Set up a budget." I've set up 47 budgets. They last about as long as my gym memberships. "Use a budgeting app." Bold of you to assume I'll open it more than once.
Most financial literacy advice is neurotypical bullsh*t wearing a helpful hat. It assumes a brain that can plan ahead, delay gratification, maintain consistent habits, and engage with boring admin without emotional shutdown. That's not your brain. That's not mine either. And pretending it is just adds another layer of shame to the pile.
A 2025 qualitative study on rejection sensitivity in ADHD found that participants consistently described an internal expectation of criticism that shaped their behaviour even when no external pressure was present. Apply that to money. Every time you check your bank balance, part of your brain is bracing for the voice that says you should be better at this by now. No wonder you avoid looking.
What actually helps (from someone who's still figuring it out)
I'm not going to pretend I've cracked this. I haven't. Some months I'm brilliant and some months I'm back to 3am bank checks and a stomach full of dread. But there are things that have made the tax smaller. Not zero. Smaller.
Separate your money physically. Not in a spreadsheet. In actual separate pots or accounts. Monzo, Starling, whatever works. Put your bills money somewhere you literally can't impulse-spend it. Make it automatic. If the decision has already been made, your brain doesn't have to make it again every month. This single thing has saved me more money than any budgeting course ever could.
Automate everything you possibly can. Direct debits for every bill. Round-ups for savings. Standing orders for rent. If it requires you to remember to do it monthly, it won't get done. That's not a personal failing. That's just maths.
Body double for money admin. Sit with a friend, a partner, anyone, and open the letters together. Check the accounts together. Make it an event instead of a solitary shame spiral. There are online body doubling communities now where you can do your life admin alongside strangers who are also doing theirs. Use them. Financial admin is infinitely less terrifying when someone else is in the room.
Give yourself a "money date." Fifteen minutes, once a week. Not to budget. Not to plan. Just to look. To break the avoidance cycle. Put a timer on. When it goes off, you're done. The point isn't to fix everything in fifteen minutes. The point is to prove to your nervous system that looking at your money isn't going to kill you.
And honestly? Forgive the months where none of this works. Because some months your executive function is just not going to show up for money admin. That's going to happen. And when it does, the worst thing you can do is pile shame on top of it. The shame makes the avoidance worse. The avoidance makes the tax higher. Break the loop wherever you can, even if "wherever you can" is just "I'm going to not hate myself for this today."
You're not bad with money. Your brain is expensive to run.
That's the reframe I want to leave you with.
You are not financially irresponsible. You are not careless. You are not the person your bank statement suggests you are on a bad month.
You are a person with a brain that costs more to operate. More energy. More systems. More workarounds. More grace. And the world hasn't caught up to that yet. The financial system hasn't caught up. The advice hasn't caught up. The people telling you to "just budget" definitely haven't caught up.
The ADHD tax is real. But it's not a character flaw. It's a design flaw in a system that was never built for how your brain works.
And if nobody's said this to you today... you're doing better than you think. The fact that you're still here, still functioning, still paying most of the bills most of the time with a brain that makes every single one of those things harder than it should be?
That's not nothing. That's a lot.
...
If the shame spiral bit hit close to home, I wrote something about why rest feels like failing with ADHD that touches on the same nervous system patterns from a different angle. Worth a read if you're in that headspace.
And if you fancy something a bit lighter after all that, you can take the quiz and find out what flavour of chaos your brain is running today. No judgement. Mostly.
Tom.
