Construction Accountant in France for Builders and Contractors

In 2026, the construction and civil engineering sector is changing: energy transition (BBC renovation, environmental qualifications), site digitalization, material and skilled labor tensions, regulatory pressure (RE2025, environmental standards). Tradesmen, VSEs and SMEs in construction (masons, electricians, plumbers, carpenters, roofers, painters, general contractors) must deal with complex accounting, multi-rate VAT, specific payroll (Building and Civil Works agreements), and structurally high working capital requirements (WCR).

Hayot Expertise is the specialized accounting firm for construction that supports your development from Paris throughout France. We cover progress accounting by site, multi-rate construction VAT (20%, 10%, 5.5%, self-assessment), construction payroll (bad weather, travel allowances, paid leave fund), retention guarantees, subcontractor management (1975 law), and environmental qualifications. For a self-employed tradesman, a 10-employee masonry LLC or a 50-employee electrical contracting corporation, we aim to optimize your taxation, secure your cash flow and save you time to focus on your sites.

Construction is a labor- and material-intensive sector with long production cycles (several months for major renovation or new construction). For long-term contracts, French GAAP allows either the percentage-of-completion or the completed-contract method; progress accounting is strongly recommended for sites over 3 months. Construction WCR is structurally heavy: you buy materials and pay salaries during the site, you invoice by monthly work situations, and you often collect with 45 to 60 days delay, or more for public contracts (60-90 days).

Progress accounting and work in progress

Progress accounting (French GAAP, article 622-2) recognizes revenue as work progresses, not at final delivery. This smooths results and better reflects the economic reality of a long site.

Progress method:

1. Work in progress: valuation of work performed but not yet invoiced (account 34 Work in progress).
2. Work situations: monthly or bi-monthly invoicing to the project owner.
3. General and final statements: final balance at work reception.
4. Provisions for completion losses: if the estimated cost of the site exceeds the sale price, obligation to record a provision (account 1516).

Our firm implements analytical accounting by site: tracking actual costs (materials, labor, subcontracting, equipment rental) and comparison with budget forecast. You can see as work progresses whether a site is profitable or loss-making, and adjust future commercial proposals.

VAT in construction: multi-rates and self-assessment

Construction VAT has 3 applicable rates (20%, 10% and 5.5%) depending on work nature and building age, plus the reverse-charge mechanism in subcontracting.

20% VAT (standard rate)

• Work on new buildings (less than 2 years of completion).
• New construction work (significant extension increasing area by more than 10%).
• Simple maintenance work on professional premises.

10% VAT (intermediate rate)

• Renovation, improvement, transformation or development work on housing completed for more than 2 years.
• Conditions: work not constituting a new building (no complete raising, no total renovation of foundations, load-bearing walls, facades…).
• Examples: bathroom renovation, parquet flooring, window replacement, facade restoration.

5.5% VAT (reduced rate for energy efficiency work)

• Energy renovation work on dwellings completed at least two years earlier, whether or not the company holds the RGE environmental qualification.
• Eligible work: thermal insulation (attics, walls, floors), heat pump, solar water heater, double-flow mechanical ventilation, high-performance windows…
• The client certifies on the quote or invoice that the reduced-rate conditions are met (forms 1300-SD and 1301-SD are still accepted if they include all the items to be certified).

⚠️ Warning: the 5.5% rate does not depend on the company's RGE environmental qualification but on the nature of the work and the performance of the equipment; the qualification does condition the client's public grants (MaPrimeRénov', CEE, éco-PTZ).

VAT self-assessment (subcontracting between taxable persons)

Since 2014, VAT is self-assessed by the client (the main contractor, a taxable person) when a construction subcontractor invoices work. The subcontractor invoices excluding VAT and mentions "VAT self-assessment by the client (art. 283, 2 nonies CGI)". The client collects and deducts VAT simultaneously (the "Autres opérations imposables" line of the CA3).

Advantages: simplification, VAT neutrality for the client, fight against carousel fraud.

Risk: qualification error (forgetting to mention self-assessment) = tax adjustment.

Our firm secures construction VAT management: verification of applicable rate per site, management of simplified and standard certificates, self-assessment processing in subcontracting, monthly or quarterly CA3 declarations.

Retention guarantees: 5% at most and release one year after reception

The project owner can retain at most 5% of each work situation amount. This retention guarantee covers the reservations made at reception. It is released:

• one year after reception, even without a formal release, unless the project owner has served a reasoned objection by registered letter (law of 16 July 1971, art. 2).
• on public contracts, within thirty days after the guarantee period expires, or after the lifting of reservations notified during that period (article R. 2191-35 of the Public Procurement Code).

Alternative: replace retention guarantee with a bank guarantee (cost 1% to 2% of guaranteed amount), which avoids blocking your cash flow.

Our firm tracks retention guarantees (account 4117 Customers - Retention guarantees) and manages release in coordination with project owners.

Management accounting: analytical tracking by site

We implement rigorous analytical accounting:

• Tracking by site: materials, labor, subcontracting, equipment rental, site expenses.
• Monthly dashboard: gross margin per site, budget/actual variances, sites in progress, loss-making sites.
• Work in progress: valuation of performed work not yet invoiced, result management.
• Cash flow forecasts: work situations to be issued, retention guarantees to be released, supplier advances.

Digital tools: integration with your business software (construction management tools) to automatically retrieve site costs.

Tax optimization: VAT, corporate tax, dividends, holding

Multi-rate construction VAT and self-assessment

• Verification of applicable rate per site (20%, 10%, 5.5%).
• Management of simplified and standard certificates (reduced-rate work).
• Self-assessment processing in subcontracting (mandatory mention on invoices).
• Monthly or quarterly CA3 declarations, VAT credit optimization.

Director compensation optimization

Construction LLC managers are often majority managers (self-employed, pay high social charges ~45% of net profit). Optimization strategies:

• Salary/dividend arbitration: for a majority manager, only the dividend fraction below 10% of share capital, share premiums and shareholder current accounts escapes self-employed social contributions; it is then subject to the 31.4% flat tax (2026 PFU) or income tax.
• Conversion to corporation: manager as employee, URSSAF contributions (~80% of net salary), and supplementary retirement (but no unemployment insurance, which the SAS president does not contribute to).
• Holding creation: dividend remittance with parent-subsidiary regime (near-exempt corporate tax), reinvestment or real estate asset management.

Our firm models scenarios and optimizes your overall compensation (salary, dividends, profit-sharing, director retirement savings) to maximize your after-tax disposable income.

Payroll and collective agreements in Building and Civil Works

Construction applies two main collective agreements:

• Building Agreements (manual workers: IDCC 1596 up to 10 employees, IDCC 1597 above; ETAM: IDCC 2609; managers: IDCC 2420): masons, plumbers, electricians, painters, roofers, carpenters.
• Civil Works Agreement (IDCC 1702): earthworks, roads, civil engineering, pipelines.

Travel and transport allowances

Construction employees are entitled to travel allowances (travel time between depot and site) and transport allowances (travel expenses). These allowances are exempt from social contributions within certain limits.

Examples:

• Short trips (less than 50 km): allowance of €7 to €12 per day depending on zones.
• Long trips (site requiring overnight stay): allowance of €50 to €90 per night + meal expenses.

Bad weather and building paid leave fund

• Bad weather compensation: in case of site stoppage due to weather (frost, snow, torrential rain…), employees can receive unemployment-bad weather allowance paid by the employer on the normal payday and then partly reimbursed by the construction paid-leave fund (CIBTP network) to which it contributes; the cost is pooled across the sector.

• Paid leave fund: in construction, paid leave is managed by an external fund. The employer pays monthly contribution (~20% of payroll) to the fund, which directly compensates the employee during leave.

Our firm outsources your construction payroll: calculation of travel allowances, bad weather management, declarations to paid leave funds, pay slips compliant with Building or Civil Works agreements, automated social declarations.

Environmental qualification and energy efficiency work

Environmental qualification has become necessary to access energy renovation markets (government energy grants, tax credits). It certifies your technical competence; it is not a condition of the 5.5% VAT rate.

Environmental qualifications by field:

• Eco-Craftsman (training + audit).
• Heat pump qualification (heat pumps).
• Solar qualification (solar water heater).
• Photovoltaic qualification (photovoltaic).
• Construction qualification (insulation, carpentry, ventilation…).

Accounting impact: training and certification expenses are deductible charges. Multi-year certifications can be capitalized and amortized over the period.

Our firm supports the environmental qualification process: tracking certification costs, tax optimization of training investments, management of 5.5% VAT certificates.

Construction certification and public contracts

Construction certification certifies your technical skills, human resources and references. It is often required to respond to public contracts (municipalities, departments, social landlords).

Advantages:

• Commercial credibility.
• Access to public contracts (thresholds from €100k to €5.404M excluding VAT depending on work).
• Financial guarantee: construction qualification facilitates obtaining bank guarantees.

Procedures: file constitution (balance sheet, site references, staff qualifications), audit visit, renewal every 4 years.

Our firm supports you in construction certification file constitution (accounting balance sheet, certificates, financial guarantees) and public tender response preparation.

Construction WCR management: advances, retentions, factoring

Construction WCR is heavy: 45 to 60 days of revenue on average, or even 90 days for public contracts. You finance materials and labor before collecting work situations.

Financing options:

• Client advances: request 10% to 30% advance on order (especially for individuals).
• Construction factoring: mobilize 80% to 90% of work situations amount upon issuance (cost 1% to 2.5% of revenue).
• Supplier credit: negotiate 45-60 days payment with material suppliers.
• Retention guarantee mobilization: replace with bank guarantee to free cash flow.

Our firm manages your WCR: 3-month cash flow forecasts, factoring negotiation with construction-specialized factors, customer account optimization (reminders, unpaid management).

Legal structuring: sole proprietorship, LLC, corporation, holding

The structure you choose affects your taxation and asset protection.

Sole proprietorship or micro-enterprise

• Classic sole proprietorship: income tax on actual profit (fully deductible charges), self-employed social charges (~45%).
• Micro-enterprise: flat-rate 50% deduction, but loss of actual charge deduction. Interesting if few charges (self-employed).

⚠️ Limit: difficulty recruiting, weak commercial credibility for large sites.

LLC or corporation

• LLC: majority manager = self-employed (charges 45%), minority manager = employee (charges 80%).
• Corporation: president = employee (charges 80%), statutory flexibility, stock options possible.

Construction holding: if you develop several activities (masonry + electrical, or competitor takeover), creating a holding corporation allows:

• Pooling profits (tax integration).
• Dividend remittance with parent-subsidiary regime (near-exempt corporate tax).
• Financing acquisitions (LBO).

Our firm structures your legal and tax setup: LLC/corporation creation, sole proprietorship to company conversion, holding creation, shareholders' agreement.

Initial situation:

• General electrical contracting LLC, €1.2M revenue, 8 employees + 2 majority managers (self-employed).
• New construction sites (buildings, offices, shops) and renovation (individuals, condominiums).
• Basic accounting: no analytical tracking by site, poorly managed VAT (20% rate applied by default), retention guarantees not tracked.
• Tight cash flow: €180k WCR (60 days of revenue), €50k bank overdraft.
• Manager compensation: 100% self-employed salary (45% social charges).

What the engagement covers:

1. Analytical accounting by site implementation: creation of site codes, cost allocation (materials, labor, subcontracting, equipment rental), actual gross margin calculation per site. Result: identification of 3 loss-making sites (negative margin) out of 15 sites in progress → adjustment of future commercial proposals.

2. Construction VAT optimization:

• Application of 10% rate on renovation sites (housing > 2 years): €12k collected VAT savings per year (recovered in cash via VAT credit).
• Self-assessment compliance with electrical subcontractors: correction of €5k wrongly collected VAT.
• Environmental qualification obtained for energy efficiency work (charging stations, photovoltaic installations): government grant eligibility.

1. Optimized manager compensation plan:

• Reduction of self-employed salary from €80k to €50k per manager.
• Distribution of €30k dividends per manager (31.4% flat tax, 2026 PFU = €9.4k taxes, vs 45% self-employed social charges = €13.5k).
• Annual savings: about €4k per manager, i.e., around €8k/year for both managers.

1. Construction factoring: factoring contract with financing of 85% of work situations upon issuance. Cost 1.8% of invoiced revenue (€21.6k/year), but immediate cash gain of €150k → bank overdraft reduction, early supplier payment with discounts (2% discount negotiation if cash payment = €12k savings/year).

Results after 12 months:

• Tax and social savings: about €8k/year (manager compensation optimization).
• Cash gain: +€150k (factoring), bank overdraft reduced to €0.
• Visibility: monthly dashboard shared with both managers (margin per site, WCR, 3-month cash flow).
• Commercial performance: abandonment of loss-making sites, refocus on profitable sites (margin > 35%), revenue stabilized at €1.2M but net profit up +25%.

Month 1: Audit and takeover

• Full accounting and tax audit (tax regime, VAT, payroll, status of sites in progress)
• Catch-up on any backlog (DSN, VAT, social and tax filings)
• Pennylane setup, bank and cash register integration, analytical link by site

Month 2: Management structuring

• Site-by-site dashboard (actual margin, WCR per project, progress rate)
• CIBTP payroll reliability, IDCC collective agreement review, minimum wages
• VAT optimization plan (5.5% / 10% / 20% plus construction subcontracting self-assessment)
• First review of retention guarantees in progress and follow-up plan

Month 3: First quarterly review

• Quarterly meeting with the director and consolidated KPIs (gross margin, net margin, collection rate)
• Tax optimization plan (legal status, dividends, holding if relevant)
• RGE / QUALIBAT recommendations if new build or energy renovation grows

Not tracking profitability by site: you may believe you are earning money, yet some sites run at a loss. Set up rigorous analytical accounting.

Mismanaging construction VAT: applying 20% by default when 10% or 5.5% would apply. Check each site with a construction accountant.

Forgetting self-assessment in subcontracting: invoicing VAT to a taxable client exposes you to a tax adjustment.

Neglecting construction payroll: errors on travel allowances, miscalculated CIBTP contributions and unprovisioned bad-weather stoppages create labor litigation and URSSAF adjustment risks.

If you operate a foreign-owned construction entity in France, post foreign workers to French sites, or subcontract for a French general contractor, the same rules apply to you, but the friction points are different. The reverse-charge mechanism (autoliquidation, article 283, 2 nonies CGI) is where overseas operators stumble most: as a subcontractor to a taxable client, you invoice excluding VAT with the mandatory wording, and a missing mention triggers a tax adjustment regardless of where your head office sits.

Three points we watch closely for cross-border construction clients:

• Payroll and posting: workers on French sites fall under the Building or Civil Works collective agreements (IDCC 1596 or 1597 for building workers depending on headcount, 1702 for civil works), with the external paid-leave and bad-weather funds (CIBTP network). These obligations follow the site, not the employer's nationality.
• VAT positioning: confirm your status as taxable client or subcontractor before the first invoice.
• Structuring: a French holding can rationalize a foreign group's local activities.
