Side hustles from home compared: where arbitrage betting fits
If you are looking for extra income from home, arbitrage betting is one option among many, and for a lot of people not the best one. This comparison puts it next to six common alternatives and judges all seven by the same criteria: start capital, hours, skill, how far it scales, the risk of losing money, taxes in Austria and Slovakia, and what tends to end it.

Seven options in one sentence each
- Freelancing: you sell a skill such as writing, design, translation, programming or bookkeeping by the hour or by the project.
- Reselling: you buy second-hand or clearance goods and sell them on online marketplaces.
- Tutoring: you teach school subjects, languages or music, online or in person.
- Surveys and cashback: you are paid small amounts for opinions or get a share of your purchases back.
- Dividend investing: you own shares or funds and receive part of company profits.
- Matched betting: you turn bookmaker sign-up and reload bonuses into cash by covering every outcome. See matched betting.
- Sure bets (arbitrage betting): you back every outcome of an event at different bookmakers when their prices disagree enough to leave a small margin. See sure betting.
The comparison table
Arbitrage and matched betting are betting and only for adults (18+). If you're younger, the other ideas on this page are the ones for you.
Typical values for a beginner. Your own situation can differ. As of October 2026.
| Option | Start capital | Hours | Skill needed | Scales with | Risk of losing money | What tends to end it |
|---|---|---|---|---|---|---|
| Freelancing | Almost none | Flexible, but client deadlines | A skill people pay for | Rates and clients | Low (unpaid invoices) | Clients leave |
| Reselling | Small (stock) | Sourcing, photos, shipping | Knowing prices | Time and storage space | Medium (unsold stock) | Platform rules, space |
| Tutoring | None | Fixed appointments | Subject knowledge, patience | Your hours only | Very low | School holidays, fewer pupils |
| Surveys and cashback | None | Small bits of time | None | Barely | Very low (your time) | Low pay per hour |
| Dividend investing | Large for noticeable amounts | Very few | Basic finance | Capital | Market losses possible | Rarely ends; dividends can be cut |
| Matched betting | Small to medium | Per offer | Reading bonus terms carefully | Number of offers | Low per offer; mistakes cost | Offers run out, bonus bans |
| Sure bets | Medium, spread over several bookmakers | About 2 h, ongoing (our model at €2,000); bets come at short notice | Accuracy, discipline | Capital, until limits | Low per bet; voids and moved prices cause losses | Account limits |
The pattern: options that depend on your skill (freelancing, tutoring) carry the least risk of losing money but scale only with your hours. Options that depend on capital (dividends, sure bets) scale with money but put that money at some risk.
Sure bets, with their real downsides
A sure bet returns a small share of what you stake, usually 0.5–2% before the event, many below 1%. A €200 sure bet at 1% leaves about €2, if every leg is placed at the shown odds and stands. So the result depends on how much you stake over a month, not on a clever idea.
- Costs come first. ArbVantage costs €97 a month. At a 1% margin you need about €9,700 in stakes a month just to cover it.
- Money is tied up. It sits at several bookmakers at once until bets settle. See starting bankroll.
- Time is short-notice. Opportunities often last minutes, so it suits people who can react a few times a day.
- Limits set the ceiling. Bookmakers cut the stakes of winning accounts, some within weeks. This is what usually ends it. See bookmaker limits.
- Losses happen. A voided leg or a price that moves before you place the second bet turns a sure bet into an ordinary bet.
A full calculation with every assumption is in arbitrage betting as a side income.
Taxes in Austria and Slovakia
A general overview, not tax advice. Rules depend on your situation, so check with the tax office or a tax adviser.
- Freelancing, tutoring and regular reselling are generally taxable income. In Austria they are usually self-employed or business income, sometimes with a trade licence (Gewerbeschein) and social insurance. Employees in Austria can generally have up to €730 a year of other income without paying tax on it (§ 41 EStG). In Slovakia such work usually needs a trade licence (živnosť) or another registered form and goes into your tax return.
- Selling your own used things now and then is generally private, not business. Marketplaces report sellers with 30 or more sales or €2,000 or more a year to the tax office (EU DAC7 rules), so keep records.
- Dividends are taxed in Austria at the 27.5% capital gains tax (KESt), usually withheld by Austrian banks. In Slovakia a withholding tax applies; check the current rate with the Financial Administration.
- Betting winnings of private bettors are generally not subject to income tax in Austria. Austrian bookmakers pay a 5% betting fee (Wettgebühr) on stakes; most absorb it, some pass it on. In Slovakia, winnings from ÚRHH-licensed operators are generally exempt. Large-scale, systematic betting can be judged differently.

Who sure betting suits, and who it doesn’t
- you have money you can genuinely do without, and are fine spreading it over several bookmakers;
- you are careful with numbers and like checklists;
- you can react to an alert a few times a day;
- you keep records and look at them honestly;
- you see it as a side project that will end when accounts get limited.
- you need the money for rent, bills or debts;
- you want something you set up once and then leave alone;
- you don’t want to verify your identity at several bookmakers;
- open bets would stress you, or you might chase losses;
- you are under 18.
If you want to try it
Start small, with two or three licensed bookmakers and money you can spare. Learn the routine with modest stakes, record every bet and check after a month whether the realised margin covers your costs. If it doesn’t, stopping is a sensible result, not a failure.
Frequently asked questions
What is the best side hustle from home?
There is no single best one. If you have a skill, freelancing or tutoring carries the least risk of losing money. Sure betting needs capital and quick reactions, and its ceiling is set by bookmaker limits.
Is arbitrage betting a good side hustle for beginners?
It can be, if you have money you can do without, are careful with numbers and accept that accounts get limited over time. Software does the searching and the stake maths, but you place every bet yourself.
Do I have to pay tax on a side income in Austria or Slovakia?
Income from freelancing, tutoring or regular reselling generally has to be declared. Private betting winnings are generally treated differently. The rules depend on your situation, so check with the tax office or a tax adviser.
Why do sure bets stop working after a while?
Bookmakers limit the stakes of customers who win consistently. Over the months, fewer accounts accept full stakes, so the activity has a natural ceiling.
