This is the same with tax collection in the US (seen different versions of this done by IRS, California’s BOE and SF treasury)
It goes something like this: they send you a scary looking letter telling you there’s something off about your taxes, you then need to call them (because they don’t do email and mailing anything will go over the time limit to comply), then they tell you more in detail what the problem is and push you to amend your return forms, once you do, you’ve legally accepted liability for whatever extra taxes they convinced you you owed (and will have to pay)
What most people should actually do: they send you a scary letter, you tell them to audit you, usually they’ll stop here, if they audit you and make a final assessment against you, you tell them you want to go to court, they’ll almost definitely drop it at this point, unless you actually owe them taxes and it’s such an easy and big case that they are willing to go through the trouble
Most people will just amend their return forms and pay, because it’s just too scary to even think of going against these agencies
Sent me a letter saying that because I had filed my federal return with my Arkansas address I clearly lived in the state, and because I hadn't filed a state return they were assessing taxes on me for the entire year at the single rate.
I called and they said the same thing, I interrupted them and said "so should I tell California to fight you over this money, since I lived there until (XX/YY/ZZZZ)?" Oh and here's my AR lease, here's my CA lease, my CA tax return, me transferring my license to an AR drivers license, and me transferring my vehicle registration on (XX/YY/ZZZZ). Anything else I can help you get from the state, since you don't seem to have access, but do from the feds.
I got the most sheepish "this case is resolved" letter from them <72 hours later.
Perhaps you have had a different experience but the IRS has always been polite and helpful in the few cases where I had income tax disputes. The key is to follow the process instead of trying to argue with bureaucrats or treat them as enemies.
Compliance deadlines are measured in months. You have plenty of time to mail responses. Usually they'll put a hold on collection activities while you have a dispute pending.
It depends on the situation. They might be polite but unwilling to budge on the issue.
My mother had a problem back before "identity theft" became a common term. Apparently someone used her SS# with their employer. The IRS was coming after her about the unreported income. Hey, that's not mine! Contact your employer and get it fixed. I've never heard of them let alone worked for them and I can't find them, can you give me their address? (This was pre-internet.) No, we aren't allowed to, you need to get it fixed.
I went off to college at that point and never learned how it ended up.
