Year-End Tax Closing: Keys to Optimizing Corporate Taxation
Corporate Income Tax is filed in July, but it is decided over the course of the year. By the time the return is due, almost every planning option is already closed off: the accounts have been drawn up, the transactions have been carried out, and the supporting documentation is whatever it happens to be.
The closing process starts in October, not December
A useful year-end review is done with enough time left to correct course. From the third quarter onward there is already enough data to estimate the year's result and, with that estimate in hand, to weigh decisions that carry a deadline: making an investment before year-end, adjusting directors' remuneration, formalizing a dividend distribution, or reviewing instalment tax payments to avoid both a surcharge and giving the Tax Agency an interest-free loan.
Accounting expense versus deductible expense
The taxable base starts from the accounting result, but it does not coincide with it. The recurring extra-accounting adjustments in small and medium-sized companies tend to cluster around a handful of items:
| Item | Usual treatment |
|---|---|
| Director's remuneration | Deductible if the position is provided for as remunerated in the bylaws and corresponds to real duties; otherwise it risks being treated as a non-deductible gratuitous transfer. |
| Client entertainment | Deductible up to a limit of 1 % of net turnover. |
| Fines and penalties | Not deductible, including late-payment surcharges. |
| Impairment of receivables | Deductible once six months have elapsed from the due date and subject to the requirements of article 13 of the Corporate Income Tax Act (LIS). |
| Vehicles with mixed use | Partial deductibility; requires evidence of the degree of business use and consistency with the input IGIC/VAT claimed. |
The common thread is evidence. An invoice is a necessary condition but not a sufficient one: the tax authorities require proof that the expense is real, that it correlates with income, and that it is properly recorded in the accounts.
Incentives lost through poor documentation
- Capitalization reserve. Allows the taxable base to be reduced for the increase in equity, provided a non-distributable reserve is set aside and the increase is maintained for the legally required period. It is lost when the reserve is not set aside within the deadline.
- Negative tax bases (tax losses carried forward). They do not expire, but their offset is capped as a percentage of turnover, and claiming them requires keeping the documentation from the year in which they were generated.
- R&D and innovation tax credit. Very valuable and heavily scrutinized on audit. Without a binding reasoned report, the risk of a tax adjustment on inspection is high.
- Free depreciation. Subject to changing requirements on workforce maintenance or asset type; the rules in force should be checked every year.
Particularities of the archipelago
A Canary Islands company operates under its own tax framework, which substantially changes the analysis: IGIC (Canary Islands General Indirect Tax, the local equivalent of VAT) instead of VAT, the Canary Islands Investment Reserve (RIC), the Canary Islands Investment Tax Credit (DIC) and, where applicable, the Canary Islands Special Zone (ZEC). The RIC, in particular, can reduce the taxable base very significantly, but it imposes obligations to actually invest the reserved amounts and maintain that investment over several years; failing to comply requires the company to regularize the position with interest.
Setting aside a RIC reserve without a realistic investment plan is one of the most frequent causes of tax regularization in the islands.
Checklist before 31 December
- Reconcile customer and supplier balances, and decide on uncollectible receivables.
- Review inventory and document any impairments.
- Verify that related-party transactions are valued at market price and properly documented.
- Check that the relevant corporate resolutions have been formalized in a public deed where required.
- Cross-check Form 347 (annual transactions return) against the customer and supplier ledgers.
- Reconcile withholdings made with the filed Forms 111, 115 and 123.
None of these points is complicated. All of them, however, turn up time and again in tax audit reports.
Two tax authorities, not one
A Canary Islands company is accountable to two separate tax authorities, and confusing them is a constant source of errors: the Spanish State Tax Agency (AEAT) for Corporate Income Tax, personal income tax withholdings, and other state-level obligations, and the Canary Islands Tax Agency for IGIC and other regionally administered taxes.
They run on separate calendars, electronic offices, and procedures. A request for information from one does not toll deadlines with the other, and an IGIC audit can run alongside a state tax inspection covering the same year without either authority being aware of the other.
