What your books have to contain
Keeping books sounds like the part of self-employment that can be improvised until an accountant sorts it out in the spring. It is the opposite: the books are the evidence, and every number on your VAT reports and your annual return is only as good as the records behind it. When those records fail, the tax due stops being a calculation and becomes an estimate made by somebody else.
What decides which books you keep
Israeli bookkeeping requirements are not one rule for everyone. They are set out in the income tax bookkeeping instructions, which are divided into schedules by type of business: a professional selling their own time, a shop, a manufacturer, a builder, a driving school, an agricultural producer. Each schedule specifies the records that trade must keep, and turnover and staff numbers move some businesses into a heavier tier.
The practical consequence is that the first question is never how much bookkeeping you feel like doing. It is which schedule you fall under, and it is worth asking your accountant explicitly rather than assuming you are in the lightest one.
Single entry and double entry
Most small service businesses keep single-entry books: a record of income, a record of expenses, and the documents behind both. It is a list of what came in and what went out, and for a consultant or a tradesperson it is genuinely sufficient.
Larger businesses, and certain trades regardless of size, must keep double-entry books, where every transaction is recorded twice and the accounts balance. This produces a full ledger and a balance sheet rather than a list, requires proper accounting software and a bookkeeper who knows how to use it, and carries a later filing deadline for the annual return.
You do not choose freely between the two. Crossing a threshold moves you, and continuing to keep a list after the requirement changed means your books no longer comply.
What every business keeps
- Documents issued to customers, in unbroken numbered sequences, one sequence per document type. Invoices, receipts, credit notes, and where relevant transaction invoices and delivery notes.
- An income record, listing what was invoiced and what was received, tied to those documents.
- An expense record, with the supplier invoice or receipt behind every line.
- Bank records for the business, which is dramatically easier when the business has an account of its own.
- Anything the schedule adds for your trade: an inventory count, work sheets, an order book, a vehicle log.
The pattern behind all of it is that every figure traces to a document, and every document is findable. A book that says 3,400 on a line with nothing attached is not a record, it is a claim.
Digital books
Records may be kept electronically, and almost everyone does. The requirement that matters is integrity: once a document is issued or an entry is made, the system must not allow it to be silently altered afterwards. A correction is a new entry that references the old one, not a rewritten cell.
This is why a spreadsheet is a poor system of record even when the arithmetic in it is right. Nothing in a spreadsheet distinguishes a figure typed today from one typed a year ago, and nothing prevents last year's invoice from being reopened and changed. It is also why invoicing software freezes a copy of every document at the moment of issue rather than regenerating it from current settings: regenerating an old invoice after your address changed would silently produce a different document from the one the customer received.
Backups are part of compliance rather than good practice alone. Records that were lost are records you cannot produce, and the obligation to produce them does not soften because a laptop failed.
How long you keep it
Books and the documents behind them are kept for seven years. That covers issued documents, supplier invoices, receipts, bank statements and the ledgers themselves. Some categories run longer, and anything connected to an asset you still own is worth keeping until well after you dispose of it, because the purchase document is what establishes your cost when the gain is calculated.
Thermal paper receipts fade to blank inside that seven-year window, sometimes within one. A photograph taken on the day is the practical answer, and it is the one genuinely convincing argument for scanning receipts as they arrive.
When books are rejected
Books can be declared unacceptable, and this is the outcome the whole system is arranged to avoid. It follows from substantive failures rather than untidiness: no numbered sequence, missing documents behind entries, income that was not recorded, a required record that was never kept at all.
The consequences are serious and compounding. The assessing officer may determine your income to the best of their judgment rather than from your figures, which means the estimate replaces your books. Deductions and benefits that depend on acceptable books can fall away. Penalties attach. And credibility, once lost, colours every subsequent year, because the next examination starts from the assumption that your records need checking.
Almost none of this is caused by sophisticated problems. The common causes are a numbering sequence with gaps in it, cash income that never reached the books, and receipts that were never kept.
A cancelled document does not free its number for reuse. Issue the credit note, keep the cancelled document in the file, and carry on with the next number. A sequence with a hole in it is the single most recognizable defect in a set of books.
Year-end tasks
- Count the inventory if your trade holds any, at or near the end of the year, and keep the count sheets. This is a documented procedure, not an estimate written afterwards.
- Check every sequence for continuity, first to last, across each document type.
- Match the books to the VAT reports. The turnover in your books and the turnover you reported to VAT should agree, and finding out in March that they do not is much better than being asked about it later.
- Confirm every expense has its document, and drop the claims that do not.
- Reconcile the bank, so that money movements and recorded transactions agree.
A workable minimum for one person
For a single-person service business, a compliant system is small: invoicing software that issues numbered documents and freezes them, a separate business bank account, a folder of supplier invoices captured as they arrive, and an accountant who sees the whole thing periodically rather than once a year in a panic.
That is genuinely all of it. The failures in small-business bookkeeping are rarely failures of sophistication; they are documents that were never captured and sequences nobody checked.
Where automation helps, and where it does not
Capture is the step worth automating. A receipt photographed at the counter is in the books, and the same receipt in a jacket pocket is a deduction you paid for and never claimed. Scanning tools do this part well.
What they do not do is decide anything. Which schedule you fall under, whether an expense is a business one, what percentage is recognized, and whether a document is a tax invoice or a card slip are not reading problems. The receipt errors guide covers where the reading itself goes wrong, and the deductible expenses guide covers the part no model should be producing for you.
General information, not tax advice for your situation. The bookkeeping schedules, thresholds and retention rules change, so confirm what applies to your trade with the Israel Tax Authority or your accountant. Next: the annual return or choosing invoicing software.
