AITA for not helping my boyfriends sister pay off her taxes?

A ripple of tension hung in the crisp Montana air as Jane, a 34-year-old career woman, found herself at a crossroads with her boyfriend’s sister. After uprooting her life for love, Jane thought staying with family would weave her into their tight-knit world. Instead, her generosity—paying rent, wrangling farm animals, and playing stand-in mom—met an audacious demand that left her stunned. Picture this: a cozy ranch house, the smell of fresh coffee, and a conversation that turned her world upside down.

What started as a chance to bond became a lesson in boundaries. Jane’s story, shared on Reddit, captures the sting of entitlement and the courage to say “no.” As readers, we’re drawn into her dilemma: was she wrong to refuse a financial favor after giving so much? Her tale sparks curiosity and empathy, inviting us to explore family dynamics, fairness, and the cost of goodwill.

‘AITA for not helping my boyfriends sister pay off her taxes?’

I'm 34F, have no kids and my boyfriend, who is 36M, has been with me for almost 2 years. My boyfriend and I wanted to have some different scenery and decided to move from Georgia to Montana about 4 months ago now, where his family resides. I have a well paying job that allows me to travel from state to state with little to no hassle so it was no inconvenience.

My boyfriend on the other hand had to uproot and find other employment. I wanted to purchase a home, because I am able to, but my boyfriend insisted that he doesnt want me footing the entire bill and suggested we stay with his sister until he finds employment because he feels like a mooch having me pay for large bills without his help.

I was against it but I agreed anyways because I had never met his family and this gave me the opportunity to bond. His sister and I grew close pretty quickly. We got along well. I am able to work from home so I have been helping her around the house with chores, feeding the farm animals, taking care of her daughter and cleaning, as well as paying her $100 a week to stay with her.

My BF just got a job so we are waiting on his first check to go out home searching. Well, about 2 weeks ago his sister asked me to watch her daughter for the week so her and her husband could take a vacation. I said yes. They were gone 11 days.

When they got home her husband I heard her and her husband discussing their plan to ask me to pay off their land and home taxes, which was around $4k. The next morning she cornered me and asked me to pay off the taxes and said 'Since you guys have been here for a few months now I think it's only fair'.

My boyfriend heard this and said 'Yeah, staying here and watching your child and paying you rent, while cleaning your house and cooking. No. She is absolutely not paying your taxes.' I agreed with him and said no, which led to her telling us we had to leave immediately. So now we are in a hotel. AITA? After all, I have been staying with her for nearly 4 months..

Family dynamics can turn a cozy stay into a financial tug-of-war. Jane’s situation, where generosity met entitlement, highlights the delicate balance of give-and-take in blended households. The sister’s bold ask for $4,000 reflects a broader issue: unspoken expectations that erode trust. Each side has a point—Jane’s contributions were substantial, but the sister may feel stretched by hosting.

This scenario mirrors a growing trend. According to a 2021 Pew Research study, 16% of U.S. adults live in multigenerational households, often sparking financial disputes. Misaligned expectations can sour relationships, especially when money’s involved.

Dr. John Gottman, a renowned relationship expert, notes, “Trust is built in very small moments, which I call ‘sliding door’ moments”. Jane’s refusal was a stand for self-respect, but the sister’s demand suggests a missed “sliding door” to clarify boundaries early. Gottman’s insight underscores the need for open communication to prevent resentment.

To navigate this, Jane could propose a family meeting to reset expectations, ensuring contributions are valued without overstepping.

Take a look at the comments from fellow users:

Reddit’s hive mind didn’t hold back, serving up a mix of sass and solidarity. From calling out the sister’s entitlement to praising Jane’s boyfriend for having her back, the comments are a spicy blend of support and shade. Here’s what they said:

MariatheRipper − Nta you wouldn't see a dime of that back. Kudos to your boyfriend for being by your side.

[Reddit User] − NTA - it sounds like the sister is money grabbing and sees your help and contribution as reason to try and get more. I feel like you have been reasonable in paying rent and helping out but this is the time to put real distance between you.

The fact they left their child with you for a week and stayed away eleven days is a big red flag - asking you to pay off their taxes ( which are their responsability) is another big red flag. Don't wait for a third, these people don't see you as a future family member, you are a meal ticket they will bleed dry if you let them.

Sit down with your bf set out your boundaries with these people ( you might want to hang out with the kids and have them over, but never stay with them for more than a short space of time) and then stick to them.

Final_Commission4160 − NTA but your boyfriend sounds like a keeper.

Ciecie33 − NTA - Sounds like this was all figured out in advance and they were ok. But, once they got to know you and get a feeling of your income, they decided to ask for a big payday. You didn't mention what your boyfriend was doing to help out, has he been doing chores also ?

Mars1040 − NTA You're doing chores, you're paying rent, you're providing free childcare, I think you're doing enough for staying there. The sister and her husband seem very entitled.. Honestly, you're better off buying your own house anyway.

[Reddit User] − NTA. Her taxes are her own business. Also who the f**k is going on vacation during a pandemic?!

BoardwalkBetty − Montana minimum wage $8.50 per hour, babysitting for 11 days. Low end Montana Housekeeper salary estimate roughly $19,000 per year. 'rent' payment of $100 per week. 16 hours per day of active babysitting =$1,496.

Roughly 3 days per week x 16 weeks of active chore help = $3,507. $100 rent payment x 16 weeks =$1,600. You have already given the Sister at least $6,600 in cash and service. You are NOT in any obligation to her. You paid your way for room and board, while also allowing her to seize an opportunity to have alone time with her husband, away from their daily routine.

While I can understand you want to be helpful and seen in good faith and favor with someone you see as a future in-law, her forwardness in asking for money now will continue throughout your relationship if boundaries are not set up here in the beginning.

BrokenAshcraft − Whyd they take an 11 day vacation if they owe 4k in taxes? Nta.

PokimaneSimp69 − NTA, you pay rent and watched her kid for a week, you don't need to pay her taxes.

[Reddit User] − NTA. Holy ENTITLED behavior, Batman! You have done more than enough. Plus, you can't change rules / expectations like that out of nowhere. I wonder how much they could have paid on their taxes with that trip money.

These hot takes are pure Reddit gold, but do they capture the full picture? Maybe the sister’s stressed, but her tax grab feels like a plot twist nobody saw coming.

Jane’s Montana misadventure reminds us that family ties can tangle when money enters the chat. Her stand against an unfair ask sparks a bigger question: where’s the line between helping out and being taken advantage of? As Jane and her boyfriend settle into their hotel, they’re likely plotting their next move—hopefully with firm boundaries in tow. What would you do if a relative hit you with a wild financial demand?
