Income basics
What counts as income, and the difference between the money agreed and the money you receive.
Income is money you receive, usually on a repeating basis. It can come from work you do, from something you own, or from support paid to you.
Different organisations count income differently. A bank assessing an application, a landlord and a tax authority may each include or exclude different items. Abiora explains the concepts; it does not decide what any organisation will accept.
Gross income is the full agreed amount before anything is taken off. Net income is what remains after deductions have been applied and is the amount that actually reaches your account.
Which deductions apply, and who removes them, depends entirely on the country and on your status. That is why the same gross amount produces a different net amount in two countries.
Some income arrives on the same date every month. Other income arrives when a client pays, when a season is good, or not at all in a quiet month.
When income is irregular, organisations usually ask for a longer history — several months or a full year — instead of a single document. That is a normal request and does not mean anything is wrong.
Employment income
Salary, wages, payslips and the deductions an employer applies.
Most payslips follow the same shape: who the employer is, which period is being paid, the gross amount, a list of deductions, and the net amount transferred.
The deduction names differ by country, and a line you do not recognise is not automatically an error. If gross minus the listed deductions does not equal the net, something on the document is missing or unclear — that is worth asking your employer about.
Where a withholding system exists, the employer removes certain amounts from your gross pay and sends them to the authority or scheme directly. Those amounts appear as separate lines on the payslip.
Employers may also pay their own contributions on top of your gross pay. Those employer contributions are not taken from you, even when the payslip lists them.
Self-employed income
Invoices, turnover, expenses and profit — and why nobody deducts tax for you.
Turnover is everything your clients paid you. Expenses are the costs of doing that work. Profit is turnover minus allowed expenses, and it is usually profit that counts as your income.
Which expenses are allowed is a country rule, not a general one. Abiora does not tell you what you may deduct — that belongs to the tax authority of your country.
Self-employed people have no employer to issue a payslip, so evidence is built from documents you or the authority produce: a submitted tax return, official confirmation of that return, invoices, and bank statements showing the money arriving.
Other income
Pensions, rent, benefits, family support and money received from abroad.
Pension payments, rent you receive, state benefits and regular family support can all be treated as income. Each usually has its own evidence: a pension statement, a tenancy agreement, a benefit award letter, or bank statements showing the transfers.
Money received from abroad is still income. Keeping the transfer receipts makes it far easier to evidence later.
Proof of income
Proof of income is any document that shows an organisation how much money you receive and where it comes from.
Banks, landlords, immigration offices and lenders ask for it because they need to see that the money is real and repeating, not a one-off.
It is a standard check. Being asked for proof of income is not a sign that you are suspected of anything.
Which documents are accepted is decided by the organisation asking, and can differ between two banks in the same country. Always check what that specific organisation lists.
Abiora explains income concepts and documents. It does not assess your income, does not decide what an organisation will accept, and is not a financial or tax adviser.
